While nasal endoscopy is typically used for diagnosis and sinus surgery, endoscopy can be combined with powered instrumentation to perform nasal septal surgery. Powered Endoscopic Nasal Septum Surgery (PENSS) is an easy, effective and quick alternative to traditional headlight approaches to septoplasty. PENSS limits the dissection to the area of the deviation and markedly reduces the extent of subperichondrial dissection. This is particularly valuable in patients who have undergone prior septal cartilage resection. PENSS was used in 2,730 patients over 8 years. Surgical indications and technique are discussed. These patients had either isolated nasal septal deformities associated with other rhinologic pathology (sinusitis, adenoid hypertrophy polyps and external nasal deformity). PENSS was utilized with video assistance to allow an enhanced view of the endoscopic operative field. These patients were operated upon in an outpatient surgical suite and were seen for a post-operative video endoscopic evaluation at 5, 10, 15 and 20 days after surgery. The patients who had associated functional endoscopic sinus surgery were evaluated as needed until 6 weeks after surgery. There were no delayed complications. Endoscopic resection of septal spurs, deformities and deviations can be performed safely alone or in combination with endoscopic sinus surgery with minimal additional morbidity.

The practice of routine nasal packing after nasal surgery is usually customary and not evidence based. Post operative complications, while uncoumon, are sometimes pack related. A retrospective analysis of 110 patients who underwent a variety of nasal operations was performed to determine the incidence of complications when nasal packs were not routinely inserted 9 cases (8.2%) [6 out of these were revision surgeries] needed nasal packing for haemostasis at the end of surgery. 4 cases (3.6%) required to be packed in the immediate post operative period. One patient who required nasal packing developed a unilateral adhesion. No patient developed septal hematoma. The need for routine nasal packing is not supported. Packing should be indicated where there continuous bleeding at.

Staphylococcus aureus nasal carriage in HIV patients remains incompletely characterized. The aim of the present study was to describe epidemiologic and molecular features of S. aureus nasal colonization in HIV outpatients. HIV outpatients with no history of hospitalization within the previous 2 years were screened for S aureus nasal colonization. Three samples were collected from each patient, and the risk factors for colonization were assessed. Nasal carriage was classified as persistent colonization, transient colonization, or no colonization. Persistent colonization was subdivided into simple (same DNA profile) or multiple (different DNA profiles) using pulsed-field gel electrophoresis (PFGE) for genotyping the strains of S. aureus. A total of 111 patients were evaluated, of which 70 (63.1%) had at least 1 positive culture for S aureus. Patients in clinical stages of AIDS were more likely to be colonized than non-AIDS patients (P = .02). Among the patients with S aureus nasal carriage, 25.2% were transient carriers and 39.4% were persistent carriers. PFGE analysis showed that the persistent colonization was simple in 24 patients and multiple in 17 patients. The HIV patients had a high rate of S. aureus nasal colonization. The most common characteristic of colonization was simple persistent colonization showing the same genomic profile.

Vitreoretinal surgery has benefited from great advances opening the opportunity for outpatient management. We report on the 6-month experience of outpatient surgery for vitreoretinal diseases. From November 2007 to April 2008, 270 patients benefited from a vitreoretinal surgery, with 173 retinal detachments, 63 epiretinal membranes, and 34 other procedures. Only 8.5% (n=23) of the patients had to stay at the hospital one or two nights. The main reasons were the distance from the hospital and surgery on a single-eye patient. The questionnaire given after the surgery showed that almost all the patients were satisfied with the outpatient setting. In contrast, the financial results showed a loss of income of around 400,000 euros due to the low level of payment of outpatient surgery in France by the national health insurance system. Vitreoretinal surgery can be achieved in outpatient surgery with an improvement in the information given to the patients and the overall organization of the hospitalization. However, the current income provided with vitreoretinal outpatient surgery is highly disadvantageous in France, preventing this method from being generalized.

Introduction There is change in nasalance post endonasal surgery which is not permanent. Objectives The objective of this study is to evaluate the long-term nasalance changes following different types of endonasal surgeries. Methods We included in this study patients who underwent sinonasal surgery at the Otorhinolaryngology Department in Zagazig University Hospitals from February 2015 until March 2016. We divided the patients into two groups according to the surgeries they underwent: Group (A) was the FESS group and group (B), the septoturbinoplasty group. We checked nasalance using a nasometer before and after the sinonasal surgery. Results Nasalance increased at one month after the operation in both groups. However, it returned to nearly original levels within three months postoperatively. Conclusion FESS, septoplasty, and turbinate surgery may lead to hypernasal speech. This hypernasal speech can be a result of change in the shape and diameter of the resonating vocal tract. Hypernasal speech in these circumstances may be a temporary finding that can decrease with time. Surgeons should inform their patients about the possibility of hypernasality after such types of surgery, especially if they are professional voice users. PMID:28382115

This study attempted to determine if sevoflurane in oxygen inhaled via a nasal hood as a sole sedative agent would provide an appropriate level of deep sedation for outpatient third molar surgery. Twenty-four patients scheduled for third molar removal were randomly assigned to receive either nasal hood inhalation sevoflurane or an intravenous deep sedation using midazolam and fentanyl followed by a propofol infusion. In addition to measuring patient, surgeon, and dentist anesthesiologist subjective satisfaction with the technique, physiological parameters, amnesia, and psychomotor recovery were also assessed. No statistically significant difference was found between the sevoflurane and midazolam-fentanyl-propofol sedative groups in physiological parameters, degree of amnesia, reported quality of sedation, or patient willingness to again undergo a similar deep sedation. A trend toward earlier recovery in the sevoflurane group was identified. Sevoflurane can be successfully employed as a deep sedative rather than a general anesthetic for extraction of third molars in healthy subjects.

The author describes his experience with 400 intranasal laser surgical procedures done with the carbon dioxide laser and the surgical microscope. Procedures include excision and vaporization of polyps, turbinates, tumors, telangiectasia, synechia, nasal stenosis, intranasal cysts, papillomata, and septal spurs. The author describes a suction speculum and drape of his own design which provide smoke free access to the internal nose, and protection of the alar rim and the face from laser energy. Relief of obstruction is comparable to that obtained from the more traditional means of intranasal surgery. Intraoperative and early and delayed post operative bleeding is less with laser surgery than with any other means. Avoidance of technical problems is emphasized in this manuscript, since intranasal laser surgery is in some respects difficult to perform. Included are practical suggestions about patient positioning, use of protective devices, and patient selection.

Nasal airway obstruction (NAO) is a common health problem with 340,000 patients undergoing surgery annually in the United States. Traditionally, otolaryngologists have focused on airspace cross-sectional areas and nasal resistance to airflow as objective measures of nasal patency, but neither of these variables correlated consistently with patients' symptoms. Given that the sensation of nasal airflow is also associated with mucosal cooling (i.e., heat loss) during inspiration, we investigated the correlation between the sensation of nasal obstruction and mucosal cooling in 10 patients before and after NAO surgery. Three-dimensional models of the nasal anatomy were created based on pre- and post-surgery computed tomography scans. Computational fluid dynamics (CFD) simulations were conducted to quantify nasal resistance and mucosal cooling. Patient-reported symptoms were measured by a visual analog scale and the Nasal Obstruction Symptom Evaluation (NOSE), a disease-specific quality of life questionnaire. Our results revealed that the subjective sensation of nasal obstruction correlated with both nasal resistance and heat loss, but the strongest correlation was between the NOSE score and the nasal surface area where heat flux exceeds 50 W /m2 . In conclusion, a significant post-operative increase in mucosal cooling correlates well with patients' perception of better nasal patency after NAO surgery.

Surgeries to correct nasal airway obstruction (NAO) often have less than desirable outcomes, partly due to the absence of an objective tool to select the most appropriate surgical approach for each patient. Computational fluid dynamics (CFD) models can be used to investigate nasal airflow, but variables need to be identified that can detect surgical changes and correlate with patient symptoms. CFD models were constructed from pre- and post-surgery computed tomography scans for 10 NAO patients showing no evidence of nasal cycling. Steady-state inspiratory airflow, nasal resistance, wall shear stress, and heat flux were computed for the main nasal cavity from nostrils to posterior nasal septum both bilaterally and unilaterally. Paired t-tests indicated that all CFD variables were significantly changed by surgery when calculated on the most obstructed side, and that airflow, nasal resistance, and heat flux were significantly changed bilaterally as well. Moderate linear correlations with patient-reported symptoms were found for airflow, heat flux, unilateral allocation of airflow, and unilateral nasal resistance as a fraction of bilateral nasal resistance when calculated on the most obstructed nasal side, suggesting that these variables may be useful for evaluating the efficacy of nasal surgery objectively. Similarity in the strengths of these correlations suggests that patient-reported symptoms may represent a constellation of effects and that these variables should be tracked concurrently during future virtual surgery planning.

BACKGROUND The efficiency of nasal surgeries can be determined by objective or subjective methods. We have assessed the effect of nasal obstruction after different nasal surgeries using Acoustic Rhinometry (AR) and Nasal Obstruction Symptom Evaluation (NOSE) Scale. METHODS Between May 2011 and May 2012, 40 young adult patients and 10 healthy volunteers as control group who referred to Otorhinolaryngology Clinic in Eskisehir Military Hospital due to nasal obstruction were enrolled. Depending on operation, patients were divided into four equal groups. Group 1: Septoplasty, Group 2: Septoplasty with sprader graft, Group 3: Septorinoplasty and Group 4: Septorhinoplasty with spreader graft. The patients completed NOSE scale, 1 week before and 1 month after the surgery and AR measurements. RESULTS There were a significant improvement in mean NOSE scores of patients and statistical difference was found between pre and post-operational values for each group. There was a statistically significant change of the mean minimal cross section areas (MCA) of the deviated side of nasal passages measured by AR between pre and postoperative period. CONCLUSION In patients with nasal obstruction, functional nasal surgeries which were performed after appropriate medical examination and with right operation methods had a positive impact on quality of life and patient satisfaction. We observed that nasal findings were correlated with NOSE scores and MCA values. So, we suggest that NOSE scale and AR to be used for evaluation of the efficiency of functional nasal surgeries.

To (1) quantify mucosal cooling (ie, heat loss) spatially in the nasal passages of nasal airway obstruction (NAO) patients before and after surgery using computational fluid dynamics (CFD) and (2) correlate mucosal cooling with patient-reported symptoms, as measured by the Nasal Obstruction Symptom Evaluation (NOSE) and a visual analog scale (VAS) for sensation of nasal airflow. Prospective. Academic tertiary medical center. Computed tomography (CT) scans and NOSE and VAS surveys were obtained from 10 patients before and after surgery to relieve NAO. Three-dimensional models of each patient's nasal anatomy were used to run steady-state CFD simulations of airflow and heat transfer during inspiration. Heat loss across the nasal vestibule and the entire nasal cavity, as well as the surface area of mucosa exposed to heat fluxes >50 W/m(2), were compared pre- and postoperatively. After surgery, heat loss increased significantly on the preoperative most obstructed side (P < .0002). A larger surface area of nasal mucosa was exposed to heat fluxes >50 W/m(2) after surgery. The best correlation between patient-reported and CFD measures of nasal patency was obtained for NOSE against surface area in which heat fluxes were >50 W/m(2) (Pearson r = -0.76). A significant postoperative increase in mucosal cooling correlates well with patients' perception of better nasal patency after NAO surgery. Computational fluid dynamics-derived heat fluxes may prove to be a valuable predictor of success in NAO surgery.

Objective To evaluate whether virtual surgery (VS) performed on 3D nasal airway models can predict post-surgical, biophysical parameters obtained by computational fluid dynamics (CFD). Methods Pre- and post- surgery CT scans of a patient undergoing septoplasty and right inferior turbinate reduction (ITR) were used to generate 3D models of the nasal airway. Prior to obtaining the post-surgery scan, the pre-surgery model was digitally altered to generate three VS models: 1) right ITR only, 2) septoplasty only, and 3) septoplasty with right ITR. The results of the VS CFD analyses were compared with post-surgical CFD outcome measures including nasal resistance, unilateral airflow allocation, and regional airflow distribution. Results Post-surgery CFD analysis and all VS models predicted similar reductions in overall nasal resistance, as well as more balanced airflow distribution between sides, primarily in the middle region, when compared with the pre-surgery state. In contrast, virtual ITR alone produced little change in either nasal resistance or regional airflow allocation. Conclusions We present an innovative approach for assessing functional outcomes of nasal surgery using CFD techniques. This preliminary study suggests that virtual nasal surgery has the potential to be a predictive tool that will enable surgeons to perform personalized nasal surgery using computer simulation techniques. Further investigation involving correlation of patient-reported measures with CFD outcome measures in multiple individuals is underway. PMID:21502467

Nasal obstruction is one of the most frequent symptoms in the ear, nose, and throat (ENT) setting. It can be evaluated either subjectively or objectively. In a subjective way, a visual analog scale (VAS) and the Sino-Nasal Outcome Test 20 (SNOT 20) can rapidly quantify the degree of obstruction, whereas the most commonly used objective methods are nasal endoscopy and active anterior rhinomanometry (AAR). It is still a matter of controversy to what extent the sense of nasal obstruction is associated with objective measures for nasal space and airflow. The aim of the study was to evaluate nasal breathing before and after functional nasal surgery by video-rhino-hygrometer (VRH) comparing the results with widely accepted methods. Twenty patient candidates for septoplasty and inferior turbinate reduction were included in the study. SNOT-20, VAS, nasal endoscopy, and AAR were analyzed and compared with VRH values. Before surgery VRH showed variability of nasal respiratory flow between individuals and between nostrils. After surgery we had an increase (p < 0.05) of airflow in both nostrils. VRH data were found to be correlated with VAS and SNOT-20 values (p < 0.05) both pre- and postoperatively. Despite the statistically significant correlation of AAR with SNOT-20 and VAS, no statistically significant correlation between AAR and VRH was found. VRH provides an immediate, easy, and noninvasive assessment of nasal respiration. For these reasons it can be used, in association with rhinoscopic data and other instrumental tests, to evaluate nasal breathing in daily ENT practice.

Solcoseryl is a biological agent, which accelerates the healing tissue procedure. This influence was studied during the nasal septum surgery. In 25 patients the postoperational nasal plug was inserted with the Solcoseryl and in 10 (control) with the paraffin. The cytologic verifications were performed before and after the surgery. In the solcoseryl group the mucosa regeneration procedure was accelerated and the inflammation reduced.

To evaluate whether virtual surgery performed on 3-dimensional (3D) nasal airway models can predict postsurgical, biophysical parameters obtained by computational fluid dynamics (CFD). Presurgery and postsurgery computed tomographic scans of a patient undergoing septoplasty and right inferior turbinate reduction (ITR) were used to generate 3D models of the nasal airway. Prior to obtaining the postsurgery scan, the presurgery model was digitally altered to generate 3 virtual surgery models: (1) right ITR only, (2) septoplasty only, and (3) septoplasty with right ITR. The results of the virtual surgery CFD analyses were compared with postsurgical CFD outcome measures including nasal resistance, unilateral airflow allocation, and regional airflow distribution. Postsurgery CFD analysis and all virtual surgery models predicted similar reductions in overall nasal resistance, as well as more balanced airflow distribution between sides, primarily in the middle region, when compared with the presurgery state. In contrast, virtual ITR alone produced little change in either nasal resistance or regional airflow allocation. We present an innovative approach for assessing functional outcomes of nasal surgery using CFD techniques. This preliminary study suggests that virtual nasal surgery has the potential to be a predictive tool that will enable surgeons to perform personalized nasal surgery using computer simulation techniques. Further investigation involving correlation of patient-reported measures with CFD outcome measures in multiple individuals is under way.

Nasal surgeries constitute an extensive manipulation of the nasal mucosa and therefore of structures related to trigeminal and olfactory sensitivity. While olfactory changes due to nasal surgery are relatively well investigated, there are only very few studies regarding trigeminal sensitivity. Aim of the present study was to investigate sensory changes after nasal surgery with special regard to the trigeminal sensitivity. In 38 patients prior to and around 12 weeks after nasal surgery the following psychophysical measures were performed: odor identification, odor discrimination, phenyl ethyl alcohol odor threshold, sensitivity to trigeminal stimuli, trigeminal detection thresholds and trigeminal pain thresholds. These results were compared to those of a control group (43 healthy volunteers). Psychophysical olfactory and trigeminal testing showed no major changes in patients after surgery compared to the control group. Independent from the time of measurement higher trigeminal detection thresholds were found in patients compared to healthy subjects, meaning that trigeminal thresholds were already increased before surgery. The present study revealed a decreased trigeminal sensitivity in patients already before surgery. It may be hypothesized that patients also exhibit a decreased sensitivity for nasal airflow, which may also contribute to the patients' impression of impaired nasal breathing.

The experience of 55 consecutive individuals undergoing outpatient vitreoretinal surgery was evaluated. Objective variables, including preoperative and intraoperative information, subjective postoperative pain, and discomfort were measured with a previously validated 100 mm visual analogue scale. Patients also ranked the overall experience. Average pain and discomfort scores in the recovery room were 21.8 and 22.6 and overnight were 26.7 and 30.4 (scale 0 to 100), respectively. Eighty eight per cent of subjects were satisfied with the experience. Elevated pain and discomfort scores were statistically correlated with scleral buckling, prolonged surgical or recovery room time, requirement for parenteral pain medications, and high intraocular pressure on the first postoperative visit. None of the patients needed further hospital treatment. This study suggests that vitreoretinal surgery in an appropriately selected population does not require routine inpatient care. PMID:1739718

CFD-derived heat fluxes may prove to be a valuable predictor of success in NAO surgery. PMID:24154749
Background Nasal colonization with methicillin-resistant Staphylococcus aureus (MRSA) is a well defined risk factor for subsequent bacteremia and death in various groups of patients, but its impact on outcome in patients receiving long-term hemodialysis (HD) is under debate. Methods This prospective interventional cohort study (performed 2004 to 2010) enrolled 289 HD outpatients of an urban dialysis-unit. Nasal swab cultures for MRSA were performed in all patients upon first admission, at transfer from another dialysis facility or readmission after hospitalisation. Nasal MRSA carriers were treated in a separate ward and received mupirocin nasal ointment. Concomitant extra-nasal MRSA colonization was treated with 0.2% chlorhexidine mouth rinse (throat) or octenidine dihydrochloride containing antiseptic soaps and 2% chlorhexidine body washes (skin). Clinical data and outcome of carriers and noncarriers were systematically analyzed. Results The screening approach identified 34 nasal MRSA carriers (11.7%). Extra-nasal MRSA colonization was observed in 11/34 (32%) nasal MRSA carriers. History of malignancy and an increased Charlson Comorbidity Index were significant predictors for nasal MRSA carriers, whereas traditional risk factors for MRSA colonization or markers of inflammation or malnutrition were not able to discriminate. Kaplan-Meier analysis demonstrated significant survival differences between MRSA carriers and noncarriers. Mupirocin ointment persistently eliminated nasal MRSA colonization in 26/34 (73.5%) patients. Persistent nasal MRSA carriers with failure of this eradication approach had an extremely poor prognosis with an all-cause mortality rate >85%. Conclusions Nasal MRSA carriage with failure of mupirocin decolonization was associated with increased mortality despite a lack of overt clinical signs of infection. Further studies are needed to demonstrate whether nasal MRSA colonization represents a novel predictor of worse outcome or just another

To demonstrate the effect of individual components of functional nasal airway surgery in a patient with multifactorial obstruction and to discuss the potential benefit of computational fluid dynamics (CFD)–aided virtual surgery. A 53-year-old woman underwent septoplasty,turbinate reduction, and nasal valve repair. Presurgery and postsurgery digital nasal models were created from computed tomographic images, and nasal resistance was calculated using CFD techniques. The digital models were then manipulated to isolate the effects of the components of the surgery, creating a nasal valverepair alone model and a septoplasty/turbinate reduction alone model. Bilateral nasal resistance in the postsurgery model was approximately 25% less than presurgery values.Similarly, CFD analysis showed reductions in nasal resistance of the virtual models: 19% reduction with intranasal surgery alone and 6% reduction with nasal valve repair alone. Most of the reduction in nasal resistance was accomplished with performance of septoplasty and inferior turbinate reduction. The contribution of nasal valve repair was less in comparison but not insignificant.This pilot study implies that CFD-aided virtual surgery may be useful as part of preoperative planning inpatients with multifactorial anatomical nasal airwayobstruction

Patients undergoing nasal surgery have historically been routinely followed up in consultant led clinics some months after surgery. It has been noted that a significant proportion of these patients either did not attend these appointments or did not require them, impacting on the efficiency of ENT outpatient clinics. A quality improvement project was undertaken to assess this problem and to propose a new patient pathway whereby patients are contacted by ENT nursing staff by telephone three months following surgery. During these telephone conversations only 9.5% of patients requested outpatient follow-up and all of these patients were discharged upon their follow-up. The project demonstrates that nurse-led follow up is an efficient, effective and safe way of managing patient care post-nasal surgery. PMID:26734352

The aim of this study was to analyze the influence of deviated nasal septum (DNS) type on nasal mucociliary clearance, quality of life (QoL), olfactory function, and efficiency of nasal surgery (septoplasty with or without inferior turbinate reduction and partial middle turbinectomy). Fifty patients (20 females and 30 males) with septal deviation were included in the study and were divided into 6 groups according to deviation type after examination by nasal endoscopy and paranasal computed tomography. The saccharin clearance test to evaluate the nasal mucociliary clearance time, Connecticut Chemosensory Clinical Research Center smell test for olfactory function, and sinonasal outcome test-22 (SNOT-22) for patient satisfaction were applied preoperatively and postoperatively at the sixth week after surgery. Nasal mucociliary clearance, smell, and SNOT-22 scores were measured before surgery and at the sixth week following surgery. No significant difference was found in olfactory and SNOT-22 scores for any of the DNS types (both convex and concave sides) (P > 0.05). In addition, there was no difference in the saccharin clearance time (SCT) of the concave and convex sides (P > 0.05). According to the DNS type, the mean SCT of the convex sides showed no difference, but that of the concave sides showed a difference in types 3, 4, 5, and 6. These types had a prolonged SCT (P < 0.05). Olfactory scores revealed no difference postoperatively in types 5 and 6 but were decreased significantly in types 1 to 4 (P < 0.05). There was no significant difference in the healing of both the mucociliary clearance (MCC) and olfactory functions. SNOT-22 results showed a significant decrease in type 3. All DNS types disturb the QoL regarding nasal MCC and olfaction functions. MCC values, olfactory function, and QoL scores are similar among the DNS types. Both sides of the DNS types affect the MCC scores symmetrically. Septal surgery improves olfaction function and QoL at the

Cartilage tissue engineering is a rapidly progressing area of regenerative medicine with advances in cell biology and scaffold engineering constantly being investigated. Many groups are now capable of making neocartilage constructs with some level of morphological, biochemical, and histological likeness to native human cartilage tissues. The application of this useful technology in articular cartilage repair is well described in the literature; however, few studies have evaluated its application in head and neck reconstruction. Although there are many studies on auricular cartilage tissue engineering, there are few studies regarding cartilage tissue engineering for complex nasal reconstruction. This study therefore highlighted the challenges involved with nasal reconstruction, with special focus on nasal cartilage tissue, and examined how advancements made in cartilage tissue engineering research could be applied to improve the clinical outcomes of total nasal reconstructive surgery.

ABSTRACT Objective: This paper deals with the investigation of the effects of nasal septal deviation evaluated by acoustic rhinometry (ARM) in the success of tympanoplasty surgery. Subject and Methods: All patients who underwent tympanoplasty surgery by the same surgeon were reviewed. The patients with nasopharyngeal or nasal masses, polyps, symptoms of allergic rhinitis or rhinosinusitis, or concha bullosa were excluded from the study. Forty patients who underwent tympanoplasty at least one year ago were included in the study. The patients were divided into two groups according to the graft success results. Acoustic rhinometry evaluations of the patients were performed. Results: There were 25 and 15 cases in the intact graft (group A) and re-perforated group (group B), respectively. For the same side of the operated ear, ARM values of group A were 0.47 cm 2 at the first narrowest cross-sectional area (MCA 1), 0.43 cm2 at the second narrowest cross-sectional area (MCA 2), 1.51 cm3 volume at the first 2 cm of the nasal cavity (Vol 1) and 3.33 cm3 volume between the second and fifth cm of the nasal cavity (Vol 2). Acoustic rhinometry values of group B were 0.50 cm2, 0.47 cm2, 1.60 cm3 and 3.19 cm3 for MCA 1, MCA 2, Vol 1, and Vol 2, respectively. Conclusion: The results of this study showed that nasal septal deviation may not affect the success of tympanoplasty surgery, and septoplasty may not be necessary before ear surgery. PMID:26624593

The aim of the study was to determine the incidence of olfactory disorders before and following nasal and paranasal sinus surgery. It was a prospective observational study. Over a 6-month period, all patients who had been listed for nasal and paranasal sinus surgery underwent preoperative and postoperative evaluation of their sense of smell. A questionnaire and the 'Smell Diskettes Test' were used to assess olfaction. One hundred and eighty-four patients were studied. Preoperatively, 19 patients (10.3%) had an impaired sense of smell (8.1% before septoplasty, 6.1% before rhinoplasty and 17.1% before endoscopic sinus surgery). Only 16 (84%) of these patients were aware of their impaired sense of smell. Following surgery, four patients (2.5%) who were normal preoperatively developed impaired olfaction on questioning, and this was supported by testing it. In the subgroup that had a septoplasty, no patient developed hyposmia compared to one patient (2.6%) after rhinoplasty and one patient (3%) after endoscopic sinus surgery. No patient developed anosmia. Preoperatively, 10.3% of patients had an altered sense of smell, making it desirable that this is documented in order to avoid postoperative claims that this was caused by surgery. It also helps to audit the results of surgery.

To assess the cost-effectiveness of outpatient sinonasal surgery in terms of clinical efficacy and control of expenses. A retrospective study was conducted from January 2014 to January 2016. Patients scheduled for outpatient sinonasal surgery were systematically included. Clinical data were extracted from surgical and anesthesiology computer files. The cost accounting methods applied in our institution were used to evaluate logistic and technical costs. The standardized hospital fees rating system based on hospital stay and severity in diagnosis-related groups (Groupes homogènes de séjours: GHS) was used to estimate institutional revenue. Over 2years, 927 outpatient surgical procedures were performed. The crossover rate to conventional hospital admission was 2.9%. In a day-1 telephone interview, 85% of patients were very satisfied with the procedure. All outpatient cases showed significantly lower costs than estimated for conventional management with overnight admission, while hospital revenue did not differ between the two. This study confirmed the efficacy of outpatient surgery in this indication. Lower costs could allow savings for the health system by readjusting the rating for the procedure. More precise assessment of cost-effectiveness will require more fine-grained studies based on micro costing at hospital level and assessment of impact on conventional surgical activity and post-discharge community care.

Introduction There are often multiple anatomic factors that contribute to nasal obstruction, creating difficulty in deciding which components to address for a successful outcome. The purpose of this pilot study is to demonstrate the effect of individual components of functional nasal airway surgery in a patient with multifactorial obstruction and discuss the potential benefit of computational fluid dynamics (CFD)-aided virtual surgery. Methods A 53 year old female underwent septoplasty, turbinate reduction, and nasal valve repair. Pre- and post-operative digital nasal models were created from CT images and nasal resistance was calculated using CFD techniques. The digital models were then manipulated to isolate the effects of the components of the surgery, creating a nasal valve repair alone model and a septoplasty/turbinate reduction alone model. Results Bilateral nasal resistance on the post-operative model was approximately 25% less than pre-operative values. Similarly, CFD analysis showed reductions in nasal resistance of the virtual models: 19% reduction with intranasal surgery alone and 6% reduction with nasal valve repair alone. Conclusions Most of the reduction in nasal resistance was accomplished with performance of septoplasty and inferior turbinate reduction. The contribution from nasal valve repair was less in comparison but not insignificant. This pilot study implies that CFD-aided virtual surgery may be useful as part of pre-operative planning in patients with multifactorial anatomic nasal airway obstruction. PMID:22508896

The purpose of this study is to identify the correlation between maxillary movement and nasal soft tissue changes on three-dimensional reconstructed cone beam computed tomography (CBCT) images after Le Fort I osteotomy. The authors also investigate the long-term change of alar base width (ABW) to determine the effect of cinch suture. The authors retrospectively studied 52 subjects (14 males and 38 females) who were treated by bimaxillary orthognathic surgery including Le Fort I osteotomy and mandibular ramus surgery. The landmarks and planes were established on three-dimensional reconstructed CBCT images. The authors measured each parameters preoperatively, 1 month postoperatively, and 1 year postoperatively. There was no significant correlation between the horizontal movement of A-point and the widening of ABW (P < 0.038), nor was there a significant correlation between the vertical movement of A-point and the change of ABW (P < 0.61). There was no significant correlation between horizontal and vertical movement of anterior nasal spine and the widening of ABW, nor was there a significant correlation between the nasal tip length and the vector of maxillary movement. There was no significant correlation between the ABW widening and the vector of surgical maxillary movement. The effect and stability of the alar base cinch suture is difficult to determine and require further investigation.

Purpose To evaluate the clinical outcomes of ambulatory buckling surgery, comparing outpatient- with inpatient-based surgery. Methods The authors performed a retrospective study of 80 consecutive cases of rhegmato genous retinal detachment from January 2009 to December 2011 treated by scleral buckling surgery. Two groups of patients were defined according to inpatient (group 1) or outpatient (group 2) surgery, and a comparison of several parameters between these two groups was performed. Results Of the 80 subjects in this study, the average age of group 1 (50 patients) was 49.7 years, and that of group 2 (30 patients) was 47.5 years. There were no statistically significant differences in the average logarithm of the minimum angle of resolution-visual acuity, the condition of the lens, or the presence of retinal lattice degeneration prior to the surgery between the groups. There were no statistically significant differences in the patterns of tear or retinal detachment or in surgical procedure between the groups. Comparing the best-corrected visual acuity after 6 months with that prior to the surgery, the changes in group 1 and group 2 were 0.26 and 0.31, respectively. The functional success rates of group 1 and group 2 after 6 months were 90% and 93%, respectively, and the anatomical success rates of group 1 and group 2 after 6 months were 94% and 96%, respectively, but these were also statistically insignificant. Conclusion Hospitalization is not essential for buckling surgery in uncomplicated rhegmatogenous retinal detachment surgery. PMID:24812485

The aim of this study is analysing the impact of the systematic versus occasional videoconferencing discussion of patients with two respiratory referral units along 6 years of time over the efficiency of the in-person outpatient clinics of a thoracic surgery service. Retrospective and comparative study of the evaluated patients through videoconferencing and in-person first visits during two equivalents periods of time: Group A (occasional discussion of cases) between 2008-2010 and Group B (weekly regular discussion) 2011-2013. Data were obtained from two prospective and electronic data bases. The number of cases discussed using e-consultation, in-person outpatient clinics evaluation and finally operated on under general anaesthesia in each period of time are presented. For efficiency criteria, the index: number of operated on cases/number of first visit outpatient clinic patients is created. Non-parametric Wilcoxon test is used for comparison. The mean number of patients evaluated at the outpatient clinics/year on group A was 563 versus 464 on group B. The median number of cases discussed using videoconferencing/year was 42 for group A versus 136 for group B. The mean number of operated cases/first visit at the outpatient clinics was 0.7 versus 0.87 in group B (P=.04). The systematic regular discussion of cases using videoconferencing has a positive impact on the efficacy of the outpatient clinics of a Thoracic Surgery Service measured in terms of operated cases/first outpatient clinics visit.

Determine the influence of general anaesthesia with closed-loop systems in the results of outpatient varicose vein surgery. Retrospective observational study including data from 270 outpatients between 2014 and 2015. The patients were divided into 2 groups according to the type of general anaesthesia used. The CL Group included patients who received propofol in closed-loop guided by BIS and remifentanil using TCI, and the C Group received non-closed-loop anaesthesia. Age, sex, surgical time, discharge time and failure of outpatient surgery were recorded. Quantitative data were checked for normal distribution by the method of Kolmogorov-Smirnov-Lilliefors. Differences between groups were analysed by a Student-t-test or Mann-Whitney-Wilcoxon test, depending on their distribution. Categorical data were analysed by a Chi-squared test. We used Kaplan-Meier estimator and the effect size (calculated by Cohen's d) to study the discharge time. Statistical analysis was performed using R 3.2.3 binary for Mac OS X 10.9. There were no significant differences in age, sex and surgical time and failure of outpatient surgery. Discharge time was different in both groups: 200 (100) vs. 180 (82.5) minutes, C Group and CL Group, respectively (data are median and interquartile rank); P=.005. The use of closed-loop devices for the hypnotic component of anaesthesia hastens discharge time. However, for this effect to be clinically significant, some improvements still need to be made in our outpatient surgery units.

Piezosurgery is a recently developed system for cutting bone without necrosis and nonmineralized tissues damage. The aim of this work has been to test Piezosurgery as a new bony scalpel in nasal surgery. In this nonrandomized study, we have performed Piezosurgery in the excision of malignant nasal tumors through a paralateronasal approach. We have used Piezosurgery on 10 patients affected by nasal adenocarcinoma. The piezoelectric device uses low-frequency ultrasonic waves (24.7-29.5 kHz); the applied power can be modulated between 2.8 and 16 W and is programmed in accordance to the density of the bone. The equipment consists of 2 hand pieces, 2 inserts, and 2 peristaltic pumps; the microvibrations that are created in the piezoelectric hand piece cause the inserts to vibrate linearly between 60 and 210 mum. In all the patients, Piezosurgery provided excellent control without bleeding and harming effects on the adjacent structures. No patients experienced adverse effects. Piezosurgery is a new and revolutionary osteotomy technique using the microvibrations of scalpels at ultrasonic frequency, so that soft tissue will not be damaged even upon accidental contact with the cutting tip. The safety of Piezosurgery as regards soft tissues was confirmed. No adverse effects were detected during unintentional contact with the tumor, nerve, vessel, and mucoperiosteum; this renders the piezoelectric device ideal for this application.

To investigate the effect of the addition of Tonimer gel spray into nasal mucosa care on nasal mucosal findings and patient comfort in the postoperative period of endonasal surgery. 40 patients who underwent endonasal surgery were included in the study. For the postoperative nasal care, isotonic saline was applied to both nasal cavities, and subsequently, Tonimer nasal gel spray was additionally applied to the right nasal cavity. Patients were examined on the 2nd, 7th, and 15th postoperative days. The findings of the examinations were scored with respect to crusting and the patient nasal comfort was assessed using the visual analog scale (VAS). The VAS values which measure patient comfort and crusting were significantly lower on the Tonimer side compared to control (p < 0.01). Tonimer and saline combination was found to be superior to saline per se in decreasing crusting and improving patient nasal comfort in the postoperative period. Copyright (c) 2007 S.

One aspect of the definition of institutional value for any program is based on the return on investment (ROI) for that program. Program requests for future resource allocations depend, in part, on that information. The purpose of this project was to determine the ROI for initial outpatient visits only for our General Thoracic Surgery (GTS) program. The number of GTS outpatient visits, studies, and requested consultations ordered by GTS surgeons only was determined after review of the hospital database and office records for the calendar year 2003. Only charges associated with the initial outpatient visits (no inpatient or physician charges) were included. Charges were based on hospital finance department data. The ROI for GTS outpatient services was calculated using total hospital costs and hospital collections. There were 689 initial outpatient GTS visits. The majority were for lung cancer (48%), benign lung diseases (21%), and esophageal diseases (14%). Total outpatient charges were 1.25M dollars and by disease process were lung cancer (644,000 dollars), benign lung disease (90,000 dollars), esophageal disease (159,000 dollars), and other (357,000 dollars). The most significant hospital charges were the following: radiology (850,000 dollars), laboratory studies (82,000 dollars), gastrointestinal medicine studies (59,000 dollars), and cardiology (42,000 dollars). Total operational costs for the GTS clinic were 415,000 dollars and hospital collections were 513,000 dollars, yielding an ROI of 98,000 dollars or an operating margin of 19%. An operating margin of 19% for GTS outpatient services is better than most Fortune 500 companies. Acquisition of this type of information by GTS surgeons may be helpful for future program development and institutional resource allocation.

In many centers, computed tomography (CT) scan is preferred over plain film radiographs in the setting of acute nasal injury because CT scan is thought to be more sensitive in predicting nasal bone fracture. However, the usefulness of CT scans in predicting the need for surgery in acute nasal injury has not been well-studied. We conducted a retrospective review of 232 patients with known nasal bone fracture and found very similar rates of surgery in patients with a diagnosis of nasal fracture by CT scan as by nasal radiographs (41 and 37%, respectively). This suggests that experienced clinical examination remains the gold standard for determining the need for surgery in isolated nasal trauma, regardless of CT findings. PMID:24436764

ABSTRACT Objective: To identify pediatric caregivers' reactions in outpatient surgery settings. Methods: A quantitative descriptive/exploratory survey-based study involving application of a semi-structured questionnaire to 62 caregivers in two hospitals. Results: Most caregivers (88.7%) were mothers who submitted to preoperative fasting with their children. Nervousness, anxiety and concern were the most common feelings reported by caregivers on the day of the surgery. Conclusion: Medical instructions regarding preoperative procedures had significant positive impacts on patient care, and on patient and caregiver stress levels. PMID:27759831

Unplanned readmission following surgery is a quality metric that helps surgeons assess initiatives targeted at improving patient care. We utilized the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database to determine the rates, causes, and predictors of unplanned 30-day readmissions after outpatient elective hand and elbow surgery. The ACS-NSQIP database was queried using hand-and-elbow-specific Current Procedural Terminology (CPT) codes to retrospectively identify patients who had undergone outpatient hand or elbow surgery in 2012 and 2013. Patients who required an unplanned readmission to the hospital within 30 days were compared with those who were not readmitted. Preoperative patient characteristics, intraoperative variables, complications, and mortality were compared between the cohorts. Cox proportional hazard models were used to determine independent associations with 30-day unplanned readmission. A total of 14,106 outpatient hand or elbow surgery procedures were identified between 2012 and 2013, and 169 (1.2%) of them were followed by an unplanned readmission. The leading causes of readmission included postoperative infections (19.5%), pain (4.7%), thromboembolic events (4.1%), and pulmonary complications (3.0%). The causes of approximately 1/3 of the readmissions were missing from the database, and these readmissions were likely unrelated to the principal procedure. Independent predictors of readmission included an age of 70 to 84 years (hazard ratio [HR] = 2.83, 95% confidence interval [CI] = 1.67 to 4.78), smoking (HR = 2.23, 95% CI = 1.57 to 3.18), a lower hematocrit (HR = 2.19, 95% CI = 1.38 to 3.46), renal dialysis (HR = 3.32, 95% CI = 1.60 to 6.91), and an elbow procedure (with or without a hand procedure) (HR = 2.19, 95% CI = 1.57 to 3.04). The prevalence of unplanned readmission following outpatient hand and elbow surgery is low. Several modifiable factors, including preoperative smoking and anemia, are

Patients with eosinophilic nasal polyposis frequently require surgery, and recurrence rates are high. We sought to assess the efficacy and safety of mepolizumab versus placebo for severe bilateral nasal polyposis. This randomized, double-blind, placebo-controlled trial recruited patients aged 18 to 70 years with recurrent nasal polyposis requiring surgery. Patients received 750 mg of intravenous mepolizumab or placebo every 4 weeks for a total of 6 doses in addition to daily topical corticosteroid treatment. The primary end point was the number of patients no longer requiring surgery at Week 25 based on a composite end point of endoscopic nasal polyp score and nasal polyposis severity visual analog scale (VAS) score. Secondary end points included change in nasal polyposis severity VAS score, endoscopic nasal polyp score, improvement in individual VAS symptoms (rhinorrhea, mucus in throat, nasal blockage, and sense of smell), patient-reported outcomes, and safety. One hundred five patients received mepolizumab (n = 54) or placebo (n = 51). A significantly greater proportion of patients in the mepolizumab group compared with the placebo group no longer required surgery at Week 25 (16 [30%] vs 5 [10%], respectively; P = .006). There was a significant improvement in nasal polyposis severity VAS score, endoscopic nasal polyp score, all individual VAS symptom scores, and Sino-Nasal Outcome Test patient-reported outcome score in the mepolizumab compared with placebo groups. Mepolizumab's safety profile was comparable with that of placebo. In patients with recurrent nasal polyposis receiving topical corticosteroids who required surgery, mepolizumab treatment led to a greater reduction in the need for surgery and a greater improvement in symptoms than placebo.

Purpose The aim of the study was to compare the efficacy of parecoxib for postoperative analgesia after endoscopic turbinate and sinus surgery with the prodrug of acetaminophen, proparacetamol. Materials and Methods Fifty American Society of Anesthesiology (ASA) physical status I-II patients, receiving functional endoscopic sinus surgery (FESS) and endoscopic turbinectomy, were investigated in a prospective, randomized, double-blind manner. After local infiltration with 1% mepivacaine, patients were randomly allocated to receive intravenous (IV) administration of either 40 mg of parecoxib (n = 25) or 2 g of proparacetamol (n = 25) 15 min before discontinuation of total IV anaesthesia with propofol and remifentanil. A blinded observer recorded the incidence and severity of pain at admission to the post anaesthesia care unit (PACU) at 10, 20, and 30 min after PACU admission, and every 1 h thereafter for the first 6 postoperative h. Results The area under the curve of VAS (AUCVAS) calculated during the study period was 669 (28 - 1901) cm·min in the proparacetamol group and 635 (26 - 1413) cm·min in the parecoxib group (p = 0.34). Rescue morphine analgesia was required by 14 patients (56%) in the proparacetamol group and 12 patients (48%) in the parecoxib (p ≥ 0.05), while mean morphine consumption was 5 - 3.5 mg and 5 - 2.0 mg in the proparacetamol groups and parecoxib, respectively (p ≥ 0.05). No differences in the incidence of side effects were recorded between the 2 groups. Patient satisfaction was similarly high in both groups, and all patients were uneventfully discharged 24 h after surgery. Conclusion In patients undergoing endoscopic nasal surgery, prior infiltration with local anaesthetics, parecoxib administered before discontinuing general anaesthetic, is not superior to proparacetamol in treating early postoperative pain.

To summarize the efficacy of Sorbalgon strips used in endoscopic sinus surgery (ESS), to explore a better nasal packing materials. From Jan. 2000 to Apr. 2003., 2013 cases with Sorbalgon strips for nasal packing of nasal chronic sinusitis and polyps after endoscopic sinus surgery, and compared with packing of Aureomycin ointment gauze. The hemostasia effect and nasal cavity response were observed. Sorbalgon strips had effectiveness at controlling hemorrhage in ESS. Comparing with aureomycin ointment gauze, Sorbalgon strips had less bleeding when being removed (P < 0.01), and the nasal cavity response was gentle (P < 0.01). The packing time with Sorbalgon strip was no more than 24 hour. No any adverse event was observed. Sorbalgon strips are a better nasal packing material used in ESS.

Throat packs are employed in nasal surgery to prevent contamination of the upper aerodigestive tract. Their use is thought to reduce the risk of aspiration and post-operative nausea and vomiting. However, use of throat packs may also be accompanied by increased throat pain. In order to inform our clinical practice, the evidence base for throat pack insertion was reviewed. A search was made of the Pubmed database from the 1950s to March 2008. Four randomised, controlled, clinical trials were reviewed. All the trials had significant methodological weakness. In all but one, no power calculations were done. There were inconsistencies in the measurement of pain and heterogeneity of rhinological procedures. The one adequately powered trial could not demonstrate a difference in post-operative nausea and vomiting with the use of throat packs (beta error = 20 per cent). Further, adequately powered trials are required involving patients undergoing rhinological procedures with a higher risk of blood contamination (e.g. functional endoscopic sinus surgery), in order to provide definitive evidence on the morbidity of throat packs in rhinological procedures.

Music has long been known to reduce anxiety, minimize the need for sedatives, and make patients feel more at ease. The purpose of the study was to evaluate the effect of music in elderly outpatients undergoing elective cataract surgery with retrobulbar block and monitored anaesthetic care using fentanyl or alfentanil and midazolam. One hundred and twenty one patients were prospectively and randomly assigned to hear: relaxing suggestions, white noise, operating room noise or relaxing music via audio-cassette headphones. Vital signs were documented before and after retrobulbar block and every 15 min thereafter. Anxiety was assessed using the State-Trait Anxiety Inventory (STAI) before and after surgery. Visual analogue scales (VAS) were used to assess anxiety and patient satisfaction postoperatively with a standardized questionnaire. Between group comparisons were made using Chi-Square, or ANOVA, where appropriate. There were no differences between groups in STAI or anxiety VAS scores at any time. Differences were noted in systolic blood pressure, but not in other vital signs. Patients' ratings of the whole operative experience, satisfaction with the tape played, general level of relaxation and preference for the chosen tape for subsequent surgery were different (music > relaxing suggestions > white noise and OR noise, P < 0.05). Elderly patients undergoing cataract surgery under retrobulbar block were more satisfied with their experience if they heard relaxing music, rather than relaxing suggestions or white noise or OR noise. The type of auditory stimuli to which the patients were exposed did not influence the level of anxiety.

German ENT clinics currently do not attach great importance to outpatient surgical procedures. However, up-to-date data on the proportion of outpatient surgeries are not yet available. In a retrospective study, outpatient surgical procedures using anesthesia or sedation at a German ENT clinic were analyzed as an illustrative case study. In 2010, the proportion of outpatient surgeries performed under anesthesia or sedation in relation to the total number of surgeries performed under anesthesia or sedation was no more than 3.1%. Although a broad range of surgeries was offered, mainly adenoidectomies were carried out. In view of the increasingly limited financial resources in the German health care system and considering the situation in international health care systems, the significance of outpatient surgical procedures in ENT clinics is expected to increase in the future. Future-oriented clinic organization should therefore include sufficient capacity for outpatient surgeries. The basic requirement is realistic cost reimbursement by the insurers.

To examine nasal airway function using a disease-specific quality-of-life survey instrument in subjects undergoing Le Fort I osteotomy without simultaneous rhinosurgical procedures. We conducted a prospective cohort study of nasal airway function in consecutive Le Fort I osteotomy patients, who had not received simultaneous rhinosurgical procedures, between 2007 and 2008 at Kaiser Permanente Oakland Medical Center. We administered the Nasal Obstruction Symptom Evaluation (NOSE) survey before and 3 months after surgery. Clinical and radiographic examinations were performed, and the relevant medical and demographic factors were analyzed. The initial study sample comprised 55 patients, of whom 5 were excluded. Of the remaining 50 patients (median age 21 years, 60% women), the maxilla was advanced (median 4 mm, interquartile range 3 to 5) with minimal vertical change. During the follow-up period (median 5.5 months), significant improvement was seen in the NOSE scores for the cohort, with a median decrease of 10 units (P = .0005). Patients with moderate nasal obstruction (preoperative NOSE score >25) had the greatest improvement (P < .001). Those with severe nasal obstruction (preoperative NOSE score >50) improved, however, this did not reach statistical significance (P < .0625). The NOSE scores worsened in 10 patients; of these, 6 had minimal change. However, 4 had significant worsening, with 2 having symptomatic complaints. No predictor variables were identified in this small subgroup; however, individual case analyses revealed 1 subject with postoperative turbinate inflammation on the side of maxillary segmentalization and 1 had nasal septal buckling. Our overall findings have suggested that nasal airway function improved after maxillary advancement and that subjects with greater preoperative NOSE scores (>25) were more likely to experience relief of nasal obstructive symptoms.

Patients with nasal polyposis (NP) complain of several sinonasal symptoms that impact their sleep and quality of life. However, data on sleep disorders related to NP symptoms, before and after surgery, is poor. The aim of the present study was to analyze sleep complaints related to each NP symptom, before and after surgery, using the Dynachron questionnaire. 63 patients operated for NP were included in this prospective study. They filled the DyNaChron questionnaire one day before surgery (V0), 6 weeks (V1) and 7 months (V2) after surgery. The self-ratings (0-10 point visual analog scale) of nasal obstruction, anterior rhinorrhea, postnasal discharge, cough and 5 items related to sleep disturbances, due to each symptom of chronic nasal dysfunction, were extracted from the questionnaire and analyzed. There was significant improvement of symptoms and symptom-related sleep disturbance scores at V1 and V2 compared to baseline scores. Before surgery, moderate/severe sleep disorders that patients attributed to nasal obstruction (the patient thinks it is due to nasal obstruction rather than a clinical test to show nasal obstruction) or anterior rhinorrhea were reported in two thirds of patients, postnasal discharge in one half, and chronic cough in one third. After surgery, less than 10% of patients reported moderate/severe sleep disorders at V1. There was a mild increase of patients who rated moderate/severe sleep disorders at V2 in comparison to V1. The correlation between scores of nasal obstruction and its impacts on sleep quality was weak before surgery and strong afterwards. Nasalization improved sleep quality significantly at 6 weeks and at 7 months after surgery. However, there was a mild increase of complaints related to postnasal discharge and cough at 7 months after surgery.

The objectives of outpatient surgery are to reduce the risks connected to hospitalization, to improve postoperative recovery and to decrease the health costs. Few studies have been performed in the field of thoracic surgery and there remains great scope for progress in outpatient lung surgery. The purpose of this article is to present a revue of the current situation and the prospects for the development of out patient thoracic surgery.
Specialty providers claim to offer a new competitive benchmark for efficient delivery of health care. This article explores this view by examining evidence for price competition between ambulatory surgery centers (ASCs) and hospital outpatient departments (HOPDs). I studied the impact of ASC market presence on actual prices paid to HOPDs during 2007-2010 for four common surgical procedures that were performed in both provider types. For the procedures examined, HOPDs received payments from commercial insurers in the range of 3.25% to 5.15% lower for each additional ASC per 100,000 persons in a market. HOPDs may have less negotiating leverage with commercial insurers on price in markets with high ASC market penetration, resulting in relatively lower prices. © The Author(s) 2016.

Background: Obstructive sleep apnea (OSA) is a common sleep disorder and is characterized by airway collapse at multiple levels of upper airway. The effectiveness of nasal surgery has been discussed in several studies and shows a promising growing interest. In this study, we intended to evaluate the effects of nasal surgery on the upper airway dimensions in patients with OSA using three-dimensional (3D) reconstruction of cone-beam computed tomography (CT). Methods: Twelve patients with moderate to severe OSA who underwent nasal surgery were included in this study. All patients were diagnosed with OSA using polysomnography (PSG) in multi sleep health centers associated with Massachusetts General Hospital, Massachusetts Eye and Ear Infirmary and the Partners Health Care from May 31, 2011 to December 14, 2013. The effect of nasal surgery was evaluated by the examination of PSG, subjective complains, and 3D reconstructed CT scan. Cross-sectional area was measured in eleven coronal levels, and nasal cavity volume was evaluated from anterior nasal spine to posterior nasal spine. The thickness of soft tissue in oral pharynx region was also measured. Results: Five out of the 12 patients were successfully treated by nasal surgery, with more than 50% drop of apnea–hypopnea index. All the 12 patients showed significant increase of cross-sectional area and volume postoperatively. The thickness of soft tissue in oral pharynx region revealed significant decrease postoperatively, which decreased from 19.14 ± 2.40 cm2 and 6.11 ± 1.76 cm2 to 17.13 ± 1.91 cm2 and 5.22 ± 1.20 cm2. Conclusions: Nasal surgery improved OSA severity as measured by PSG, subjective complaints, and 3D reconstructed CT scan. 3D assessment of upper airway can play an important role in the evaluation of treatment outcome.

Obstructive sleep apnea is a major complication of pharyngeal flap surgery. The purpose of the present study is to predict preoperatively the risk of upper airway obstruction after surgery. We performed an overnight sleep study preoperatively and postoperatively in 16 pediatric patients considered for pharyngeal flap surgery. Preoperative sleep study was done for two nights, once in normal breathing condition and once with complete nasal occlusion by packing of nostril with tampon gauze. In preoperative sleep recordings in normal breathing condition, all subjects had a normal apnea hypopnea index (AHI) less than 5/h. In preoperative recording with complete nasal occlusion, five patients exceeded 5/h in AHI. In particular, for two patients who had AHI higher than 15/h, we gave up a surgery in one case and performed pharyngeal flap operation for the other following a tracheotomy for severe disturbance of oral breathing. The remaining 14 subjects underwent surgery without airway obstructive complications. There was strong correlation between preoperative AHI with nasal tampon gauze and AHI at two weeks postoperatively (r = 0.88 P < .0001). There was no significant correlation between preoperative AHI in normal breathing condition and postoperative AHI (P > .05). These results exhibit preoperative sleep study with complete nasal airway occlusion represent postoperative breathing condition well during early postoperative period. Preoperative sleep study with complete nasal airway occlusion with nasal tampons could be useful for predicting the risk of upper airway obstruction secondary to pharyngeal flap surgery.

In the present study, we reconstructed upper airway and soft palate models of 3 obstructive sleep apnea—hypopnea syndrome (OSAHS) patients with nasal obstruction. The airflow distribution and movement of the soft palate before and after surgery were described by a numerical simulation method. The curative effect of nasal surgery was evaluated for the three patients with OSAHS. The degree of nasal obstruction in the 3 patients was improved after surgery. For 2 patients with mild OSAHS, the upper airway resistance and soft palate displacement were reduced after surgery. These changes contributed to the mitigation of respiratory airflow limitation. For the patient with severe OSAHS, the upper airway resistance and soft palate displacement increased after surgery, which aggravated the airway obstruction. The efficacy of nasal surgery for patients with OSAHS is determined by the degree of improvement in nasal obstruction and whether the effects on the pharynx are beneficial. Numerical simulation results are consistent with the polysomnogram (PSG) test results, chief complaints, and clinical findings, and can indirectly reflect the degree of nasal patency and improvement of snoring symptoms, and further, provide a theoretical basis to solve relevant clinical problems.

To describe the efficacy of Functional Endoscopic Sinus Surgery(FESS) in our set up in comparison with other published studies to treat primary and recurrent nasal polyposis. This descriptive study was conducted in 02 years at Ear Nose Throat Department Combined Military Hospital (CMH) Multan from October 2013 to October 2015. Convenient sample comprising 116 patients of both sexes of age group from 18 to 60 years were selected from ENT Out Patient Department, with documented diagnosis of nasal polyposis that underwent functional endoscopic sinus surgery. Out of 116 patients, 15 (12.9%) had recurrent nasal polyposis while 101 (87.1%) had primary nasal polyposis. Patients were assessed clinically. Preoperative nasal endoscopy and CT scan of nose and paranasal sinuses were performed in every patient to assess the extent of disease and evaluate the surgical anatomy. Patients were followed up 03 monthly, 06 monthly and after 01 year. Clinical signs of nasal polyposis were evaluated by nasal endoscopy at each follow up visit. There were 116 patients with documented diagnosis of nasal polyposis. Among these, 75 (64.7%) were male and 41 (35.3%) were female patients. Mean age of presentation in males was 39.1 years and that of females was 36.7 years. Only 15 patients (12.9%) developed recurrent disease within a year. Functional endoscopic sinus surgery is preferred as a primary treatment modality for primary and recurrent nasal polyposis. Mucosal polyps can be carefully debrided, the natural ostia enlarged, the ethmoid sinuses are unroofed, and sphenoid sinuses are opened in nasal cavity and sinus nasal mucosa is mostly preserved due to excellent visualization and surgical technique. Improvement in symptoms with minimal chance of recurrence may be expected in more than 90% patients.

Introduction: The creation of Outpatient Surgery (OPS) units to combine the quality of medical attention and rationalize costs allows for greater efficiency in the use of resources. Aim: To report our series of patients undergoing surgery at the OPS units integrated into our Hospital (Type II): Patients and method: Between May 1994 and March 1998, 832 outpatients, of a total of 5230, underwent surgery at our General Surgery Unit. The criteria for exclusion from the programme depended on the patient and the enviroment or resulted from the operation itself. Results: Mean patient age was 47.5 years; there were 420 males and 412 females. Surgery was performed for 229 inguinofemoral hernias, 47 umbilical-epigastric hernias, nine incisional hernias, 193 pilonidal sinuses, 156 mammary nodules, 65 varicose veins, 64 arteriovenous fistulae and 69 proctology operations. The most common anesthesia techniques performed were rachianesthesia and local anesthesia. Eight point seven percent of the patients required admission (OPS failure), the most frequent causes being excessive pain, orthostatic-syncopal hypotension, nausea and vomiting and urine retention. There was no morbidity or mortality. Conclusion: OPS is a highly efficient procedure for resolving the most common pathologies in General Surgery. The anesthesia technique was an important factor in the rate of failure.

To identify pediatric caregivers' reactions in outpatient surgery settings. A quantitative descriptive/exploratory survey-based study involving application of a semi-structured questionnaire to 62 caregivers in two hospitals. Most caregivers (88.7%) were mothers who submitted to preoperative fasting with their children. Nervousness, anxiety and concern were the most common feelings reported by caregivers on the day of the surgery. Medical instructions regarding preoperative procedures had significant positive impacts on patient care, and on patient and caregiver stress levels. Identificar as reações dos acompanhantes de crianças submetidas à cirurgia ambulatorial. Estudo survey descritivo/ exploratório, de caráter quantitativo, realizado em dois hospitais com 62 acompanhantes que responderam um questionário semiestruturado. Constatou-se que a maioria dos acompanhantes era formada por mães (88,7%) e permaneceu em jejum junto das crianças. Todos os acompanhantes referiram sentimentos identificados como nervosismo, ansiedade e preocupação. A orientação médica aos procedimentos pré-operatórios foi de grande importância, não somente para o cuidado da criança, mas também do acompanhante, visando diminuir ao máximo o estresse vivenciado por eles.
Dramatic changes in outpatient surgery have occurred in recent years, but the basic care needs of surgical patients remain constant. Most outpatients face the same spiritual and coping issues that inpatients do, but outpatient surgery requires that patients cope with the surgery at an accelerated pace. This phenomenological study describes the meanings of the lived spiritual experiences of patients transitioning through major outpatient surgery. Analysis of interviews with participants resulted in four distinct themes: a point in time, holy other, vulnerability in the OR, and appraisals of uncertainty. Ways that health care providers can provide holistic case include developing an understanding of the patient's overall experience, understanding the patient's goals, and supporting the patient's own coping mechanisms and resources. Additional research should be conducted to explore interventions related to patients' spiritual well-being in outpatient settings.

Ambulatory or outpatient anaesthesia is performed in patients who are discharged on the same day as their surgery. Perioperative complications such as postoperative nausea and vomiting (PONV), postoperative behavioural disturbances and cardiorespiratory complications should be minimized in ambulatory anaesthesia. The choice of anaesthetic agents and techniques can influence the occurrence of these complications and thus delay in discharge. The objective of this review was to evaluate the risk of complications (the risk of postoperative nausea and vomiting (PONV), admission or readmission to hospital, postoperative behavioural disturbances and perioperative respiratory and cardiovascular complications) and recovery times (time to discharge from recovery ward and time to discharge from hospital) comparing the use of intravenous to inhalational anaesthesia for paediatric outpatient surgery. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (2013, Issue 8); MEDLINE (1948 to 1 October 2013); EMBASE (1974 to 1 October 2013); Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) (1982 to 1 October 2013). We also handsearched relevant journals and searched the reference lists of the articles identified. We included randomized controlled trials comparing paediatric outpatient surgery using intravenous versus inhalational anaesthesia. Two review authors independently assessed trial quality and extracted the data. When necessary, we requested additional information and clarification of published data from the authors of individual trials. We included 16 trials that involved 900 children in this review. Half of all the studies did not describe the generation of randomized sequence and most studies did not describe adequate allocation sequence concealment. The included studies showed variability in the types and combinations of drugs and the duration of anaesthesia, limiting the meta-analysis and interpretation

Objective: To investigate the clinical features of epistaxis in the posterior fornix of the inferior nasal meatus and compare the treatment outcomes of endoscopic surgery and conventional nasal packing for this intractable form of epistaxis. Methods: Between August 2011 and August 2014, the medical records of 53 adult patients with idiopathic epistaxis in the posterior fornix of the inferior nasal meatus diagnosed by nasal endoscopy were obtained from our department. Of these, 38 patients underwent endoscopic surgery (surgery group) and 15 received a nasal pack (packing group). The patients’ background characteristics, incidence of re-bleeding, extent of discomfort after treatment as assessed using a 10-point visual analogue scale (VAS) and incidence of nasal cavity adhesion after treatment were analysed. Results: There were no significant differences in background characteristics between the two groups. The incidence of re-bleeding (0/38 vs. 4/15, surgery vs. control, P = 0.001), VAS score for discomfort (2.4 ± 1.4 vs. 7.6 ± 1.0, surgery vs. control, P = 0.001) and incidence of nasal cavity adhesion after treatment (2/38 vs. 7/15, surgery vs. control, P = 0.007) were significantly lower in the surgery group than in the packing group. Conclusion: Endoscopic surgery is superior to conventional nasal packing for the management of epistaxis in the posterior fornix of the inferior nasal meatus. During surgery, it is crucial to expose the bleeding sites by shifting the inferior turbinate inward by fracture. PMID:26870097

Staphylococcus aureus nasal colonization is a risk factor for surgical site infection. We conducted a retrospective case-control study of 1,708 consecutively enrolled patients to identify criteria that places orthopaedic surgery patients undergoing spine and total joint arthroplasty surgery at risk for nasal colonization by MRSA and MSSA. Multivariate analysis showed obesity and asthma as significant risk factors for MRSA colonization. The identification of these two risk factors for MRSA colonization may help decolonization programs target patients with these factors for treatment prior to surgery, which could potentially lead to reductions in the rates of surgical site infections.

Conventional treatment for nasal augmentation utilizes autologous grafts, allografts, or synthetic implants such as silicon implants. Silicon implants could protrude/expose or induce nasal bone resorption. Autologous grafts are usually associated with donor site morbidity and the volume of harvested tissue is limited. We had developed a new method for nasal augmentation using cultured autologous chondrocytes (CAC). The current report presents the results of a study using that method with a larger number of patients and an improved graft technique for the nasal tip. Approximately 1 cm2 of cartilage was harvested from the auricular concha and treated with collagenase, and then chondrocytes were obtained. In our multilayer culture system the chondrocytes formed immature cartilaginous tissues with a gelatinous chondroid matrix. They were injection-grafted into the subcutaneous pocket of the nasal dorsum. The chondrocytes with a gelatinous chondroid matrix change from a soft gel to hard neocartilage tissue within 2 to 3 weeks and then stabilize. The authors have used this procedure over a 6-year period on 75 cases: 58 secondary augmentation rhinoplasties following silicon implantation and 17 primary augmentation cases. The results have been satisfactory and long-lasting. Grafting of CAC is an optional method for nasal augmentation and could be used for a wide range of facial augmentation cases.

Nasal packing is routinely used in septal surgery to prevent postoperative bleeding. To demonstrate the possibility of transeptal suture as a safe and effective way to avoid nasal packing and to improve efficiency. This is a prospective, descriptive, inferential cost study comprising 92 patients. Two randomized groups of patients were analyzed, one with nasal packing and the other with transeptal suture. In the group of transeptal suture no patient experienced postoperative bleeding, and a statistically significant reduction of pain and headache was demonstrated. At the same time, we improved efficiency by saving on material costs. Transeptal suture is an effective and safe alternative to classic nasal packing in septal surgery. Moreover, it improves the efficiency of the intervention by saving costs. Copyright © 2015 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial. Published by Elsevier Editora Ltda.

The Internet has become an important source of medical information for patients. However, the availability of this resource for individuals in the lower socioeconomic groups is limited, a concept termed the digital divide. To evaluate this phenomenon, we conducted a survey study to quantify the accessibility and use of the Internet for obtaining medical information in an outpatient hand surgery clinic population. A 28-question survey was distributed to 207 patients concerning computer accessibility, Internet use for medical and nonmedical information, Internet trust and security, and patient economic demographics. After analysis of the data, we found individuals in households with higher incomes had a greater likelihood of owning computers than those in lower income brackets. As income increases, the time spent on the Internet also increases. Another statistically significant trend was that higher income patient households thought that Internet information was trustworthy, secure, and private compared with the lower income brackets. We concluded that clinical settings where the predominant patient population earns less than $18,000 may not benefit or use physician Internet-based services or information. The concept of the digital divide seems to be a real phenomenon in the clinical practice of orthopaedics.

The aim of this study was to evaluate the effects of inferior turbinate surgery on nasal airway heating capacity using computational fluid dynamics (CFD) simulations. Heat transfer simulations were performed for a normal nasal cavity and others with severely enlarged inferior turbinates, before and after three simulated surgical procedures: (1) resection of the lower third free edge of the inferior turbinate, (2) excision of the head of the inferior turbinate, and (3) radical inferior turbinate resection. The models were run with three different environmental temperatures. The changes of airflow pattern with the reduction of inferior turbinate affected heat transfer greatly. However, the distribution of wall heat flux showed that the main location for heat exchange was still the anterior region. Under the cold environment, the nasal cavities with the head of inferior turbinate reduction were capable of heating the inspired air to 98.40% of that of the healthy one; however, for the case with lower third of inferior turbinate excised, the temperature was 11.65% lower and for the case with radical inferior turbinate resection, 18.27% lower temperature compared with the healthy nasal cavity. The healthy nasal cavity is able to warm up or cool down the inspiratory airflow under different environmental temperature conditions; for the nasal cavities with turbinate surgeries, partial inferior turbinate reduction can still sustain such heating capacity. However, too much or total turbinate resection may impair the normal function of temperature adjustment by nasal mucosa.

Obese patients are considered at risk of respiratory failure after cardiothoracic surgery. High-flow nasal cannula has demonstrated its non-inferiority after cardiothoracic surgery compared to noninvasive ventilation (NIV), which is the recommended treatment in obese patients. We hypothesized that NIV was superior to high-flow nasal cannula for preventing or resolving acute respiratory failure after cardiothoracic surgery in this population. We performed a post hoc analysis of a randomized, controlled trial. Obese subjects were randomly assigned to receive NIV for at least 4 h/d (inspiratory pressure, 8 cm H2O; expiratory pressure, 4 cm H2O; FIO2 , 0.5) or high-flow nasal cannula delivered continuously (flow, 50 L/min, FIO2 0.5). Treatment failure (defined as re-intubation, switch to the other treatment, or premature discontinuation) occurred in 21 of 136 (15.4%, 95% CI 9.8-22.6%) subjects with NIV compared to 18 of 135 (13.3%, 95% CI 8.1-20.3%) subjects with high-flow nasal cannula (P = .62). No significant differences were found for dyspnea and comfort scores. Skin breakdown was significantly more common with NIV after 24 h (9.2%, 95% CI 5.0-16.0 vs 1.6%, 95% CI 1.0-6.0; P = .01). No significant differences were found for ICU mortality (5.9% for subjects with NIV vs 2.2% for subjects with high-flow nasal cannula, P = .22) or for any of the other secondary outcomes. Among obese cardiothoracic surgery subjects with or without respiratory failure, the use of continuous high-flow nasal cannula compared to intermittent NIV (8/4 cm H2O) did not result in a worse rate of treatment failure. Because high-flow nasal cannula presents some advantages, it may be used instead of NIV in obese patients after cardiothoracic surgery. Copyright © 2017 by Daedalus Enterprises.

The short route is an outpatient surgical unit characterised by immediate proximity to the operating theatre. It is an organisational and architectural concept in which the patient management aims to be personalised and safe. After the procedure, patients are monitored for as long as necessary, as with traditional outpatient surgery, before being discharged.

Chronic Rhinosinusitis with Nasal Polyposis (CRSwNP) is a chronic disease that has a major impact on generic and disease-specific quality of life. Little is known about the influence of CRSwNP on sleep and what effect surgery for CRSwNP has on sleep quality. The aim of the study was to investigate sleep quality in patients with CRSwNP before and after endoscopic surgery. Forty-two patients filled out four validated sleep questionnaires and one sino/nasal, disease specific quality of life questionnaire before surgery and three months later. A healthy control group filled out the same questionnaires at baseline and after three months. An impact on sleep patterns was found in all sleep questionnaires and surgery clearly improved the quality of sleep. The Sino-nasal outcome test sum score decreased from median 51,5 to 26,5. Epworth sleepiness scale showed a decline in score from score 7.5 to 6.0. Surgery also reduced the risk for obstructive sleep apnoea in 13 patients evaluated by the Berlin Questionnaire and Multivariable Apnea Prediction Index. Patients with CRSwNP had impaired sleep quality, daytime sleepiness, nasal patency, and risk for sleep apnea, all of which improved after corrective surgery.

The outpatient surgery program from our department has started in 2014 to improve patient access to surgery and to reduce the surgical waitlist. Focused on the thoracic surgery, the most common intervention is the surgical treatment of primary hyperhidrosis by thoracic sympathectomy by video-assisted thoracoscopic surgery (VATS). It is performed according to the patient's symptoms, with section or application of surgical clips between R2-R5. Retrospective study including all the patients submitted to thoracic sympathectomy by video- -assisted thoracoscopy surgery from our department's outpatient surgery program from January 2014 to January 2016. In our outpatient program we performed 198 thoracic sympathectomy by VATS. The mean age of the patients was 32,8 years old. 63,6% of the patients were females and 36.4% were males. From the 198 endoscopic thoracic sympathectomy performed, 181 (91,4%) were performed bilatellary with section between R3-R5, 12 (6,1%) were performed with the application of surgical clips in R2-R4 and 3 (1.5%) could not be performed due to the presence of pleuropulmonary adhesions. One of the patients was re-operated due to recurrent symptoms and another patients had surgery to remove the surgical clips (bilaterally in R2) due to exaggerated abdominal compensatory hyperhidrosis. Three patients had pneumothorax. The surgical treatment of primary hyperhidrosis was the most frequent procedure in our outpatient surgery program. The procedure without the use of a thoracic drainage allowed its inclusion in the outpatient surgery program. Excluding 3 patients, all the patients were discharged within 12 hours after the surgery. The good results and the reduction of the surgical waitlist encourage the cardiothoracic outpatient surgery program.

Abstract Background: Nasal surgeries have been applied to obstructive sleep apnea (OSA) patients with nasal obstruction for decades. However, the efficiency of nasal surgery in improving OSA remains controversial. The aim of this study was to identify whether isolated nasal surgery can improve apnea–hypopnea index (AHI). Methods: Computerized searches were performed in MEDLINE, Web of Science, Cochrane Library, and Scopus from January 1, 2000 to April 30, 2016. A total of 18 articles and 587 participants were included. There were 1 randomized controlled trials, 2 nonrandomized trials, 11 prospective studies, and 4 retrospective studies. Data regarding study design (prospective/retrospective clinical trial, randomized, and controlled), population size, participant characteristics (age, gender, and body mass index), surgical intervention, and outcomes (AHI, Epworth sleep scale [ESS]) was collected. Results: Statistically significant improvement in AHI (subgroup 1: weighted mean difference [WMD] [95%confidence interval (CI)], −4.17 [−7.62, −0.73]; subgroup 2: WMD [95%CI], −4.19 [−7.51, −0.88]; overall: WMD [95%CI], −4.15 [−6.48, −1.82]) and ESS (subgroup 1: WMD [95%CI], −2.14 [−3.08, −1.19]; subgroup 2: WMD [95%CI], −4.70 [−5.95, −3.44]; overall: WMD [95%CI], −4.08 [−5.27, −2.88]) was revealed. Conclusion: Both AHI and ESS improved significantly after isolated nasal surgery, but the improvement of AHI is slightly significant. Future randomized controlled trials are needed to confirm the long-term benefits of nasal surgery on OSA. PMID:28151900

Mupirocin applied to the anterior nares four times daily usually eliminates Staphylococcus aureus, including methicillin resistant, within 48 hours. Prophylactic intranasal mupirocin is safe, inexpensive and effective in reducing the overall sternal wound infection after open-heart surgery. This study was designed to determine whether decreasing nasal bacterial colonization by applying mupirocin intra nasally decreases mediastinal, sternal, pulmonary and cutaneous infections after open-heart surgery. After institutional approval and informed consent, 392 patients were included in a randomized, prospective study. Nasal cultures were taken for all patients before surgery. Patients were divided in two groups: Group I (n = 190) receiving mupirocin in the anterior nares 4 times daily for 48 hours before surgery; Group II (n = 202) was the control group. Patients were followed for a month after surgery. All mediastinal, sternal, pulmonary and cutaneous infections were documented and treated with appropriate antibiotics. A Student test for quantitative data and a chi2 test for qualitative data were used for statistical analysis. p < or = 0.05 was considered significant. The two groups had the same demographic characteristics and risk factors. Nasal carriage of Staphylococcus was 36.2% in the two groups. Neither mediastinitis nor sternitis were noticed in any of the two groups. There was no statistical difference between the groups according to the frequency of the cutaneous infections (Group I: 19/190 - Group II: 13/202) and pneumonia (Group I: 7/190 - Group II: 13/202). In patients who had nasal carriage of Staphylococcus, nasal decontamination has not shown a statistical difference of cutaneous infections of the lower limbs nor pneumonia. Although nasal decontamination reduced the incidence of sternal wound infection (Gr I 0/190 - Gr II 4/202 ; p = 0.017). Staphylococcus aureus, in the control group, induced more cutaneous infections (30.8% vs 11.7% ; p = 0.048). The

Background: Nose is used as a corridor in endoscopic endonasal transsphenoidal approach (EETSA) for pituitary adenoma. Thus, it may affect the nasal airway patency, function and sinonasal-related quality of life. The aim of this study is to objectively and subjectively evaluate these effects. Methods: In this prospective study, 43 patients with pituitary adenoma who were candidates for EETSA from March 2012 to October 2013 were enrolled. The patients were evaluated preoperatively using acoustic rhinometry and rhinomanometry (with/without the use of decongestant drops) and asked to complete the 22-Item Sinonasal Outcome Test (SNOT-22) questionnaire. The tests were repeated at one and three months postoperatively. The preoperative data were compared with the first and second postoperative ones using paired-sample t-test. Results: Without the use of decongestant drops, the total airway resistance increased significantly (p=0.016), and the nasal airflow decreased significantly (p=0.031) in the first postoperative evaluation. However, in the 3rd postoperative month, the difference was not significant. With the use of decongestant drops, the objective parameters showed no significant changes compared to preoperative data even at the first evaluation. The SNOT- 22 scores also did not differ significantly in 1st and 3rd postoperative months. The first postoperative SNOT-22 showed a strong correlation with the second minimal cross-sectional area on simultaneous evaluation, and with the preoperative total airway resistance. Conclusion: EETSA has a transient adverse effect on the nasal patency that quickly improves, making it a safe approach for the sinonasal system. Rhinomanometry is the most sensitive test for detecting these nasal functional changes objectively. PMID:27493923

In 2008, Medicare implemented a new payment policy for ambulatory surgical centers (ASCs), which aligns the ASC payment system with that used for hospital outpatient departments and reimburses ASCs approximately 65% of what hospitals receive for the same outpatient surgery. The authors assess patient selection across ASCs and hospital outpatient departments for four common surgeries (colonoscopy, hernia repair, knee arthroscopy, cataract repair), using data on procedures performed in Florida from 2004 to 2008. The authors construct measures of patient illness severity and cost risk and find that ASCs benefit from positive selection. Nonetheless, the degree of selection varies by surgery type and patient population. While similar studies in other states are needed, the findings suggest that modifications to the Medicare outpatient payment system may be appropriate to account for the different populations that each setting attracts.

An eyelid or orbital lipogranuloma can occur following nasal packing with liquid paraffin, petroleum jelly or an antibiotic-based cream. It usually presents a few weeks or months after the initial procedure. We present a report of three such cases of sclerosing lipogranuloma involving the eyelid, which occurred following a sinonasal surgery where nasal packing using petroleum jelly was performed. The typical clinical course and the classical histopathological features are highlighted. All cases were diagnosed by histopathological examination as sclerosing lipogranuloma. Complete surgical removal resulted in complete resolution on 1 month follow-up. The diagnosis is based on a high degree of suspicion following a detailed history of prior use of lipid-based products for nasal packing following endonasal surgery. Histopathology is diagnostic. Surgical excision is the treatment of choice, however, due to its infiltrative nature, it may be difficult to obtain a complete cure. PMID:25750223

Surgical treatment for chronic rhinosinusitis with nasal polyps (CRSwNP) is often followed by polyp regrowth with return of symptoms. The purpose of this study is to identify clinical factors that influence the time interval to revision sinus surgery in patients with nasal polyps. Retrospective cohort study. Records of 299 individuals who underwent two or more surgeries for the diagnosis of nasal polyps by the senior author (RM) from 1987 through 2011 were reviewed. The time between surgical interventions were compared to patient demographics, comorbidities, endoscopic examination, computed tomography (CT) stage, extent of surgery, and pathologic findings. The mean time interval between polyp surgeries was 4.87 ± 3.61 years (range 0.7-18.6 years). The median time to revision surgery was shorter in patients who smoked compared to nonsmokers (2.82 vs. 4.31 years, respectively, P = .022) and longer in patients who underwent middle turbinate resection rather than preservation (4.56 vs. 3.93 years, respectively, P = .048). Kaplan-Meier survival analysis confirmed these findings, but the beneficial effect of turbinectomy appeared to dissipate by 8 years. Neither a history of asthma nor advanced CT stage influenced the time to revision surgery. The time course between sinus surgeries in patients with regrowth of nasal polyps appears to be affected by certain modifiable extrinsic factors, including smoking on the part of the patient and operative technique on the part of the surgeon. The performance of middle turbinate resection during sinus surgery appears to extend the time interval until a revision procedure is required. © 2013 The American Laryngological, Rhinological and Otological Society, Inc.
Background: Rhinoplasty has traditionally been preferred for correction of nasal defects. Long-term clinical experience with hyaluronic acid (HA) injection as an alternative or complement to rhinoplasty is presented. Methods: A retrospective review of the author’s clinical experience with HA gel for nasal reshaping from 1997 to 2012 was conducted, with treatments performed during 1998, 2005, and 2012 selected for detailed review. Results: More than 250 patients were treated for nasal reshaping with HA since 1997. In addition to being a complement to surgery, HA injection successfully addressed nasal defects that would have been difficult to correct surgically. The effect persisted for >1 year in most patients (>5 y in some patients), with individual variations. No serious complications occurred. When comparing the 3 years reviewed in detail, new indications for nasal reshaping with HA gel became evident over time, which was also reflected by the increase in number of patients treated (1998: n = 2; 2005: n = 22; 2012: n = 51). Of these patients, 55 (73%) received HA injection instead of rhinoplasty, 20 (27%) received HA injection after rhinoplasty, and 5 (7%) underwent rhinoplasty after HA injection. The mean injection volume was 0.4 mL HA gel/treatment. All patients were satisfied with the primary outcome of treatment. Retreatment was performed in 32 patients (43%). Conclusions: Injection of HA gel is a valuable tool for nasal reshaping. It can also be used for correction of minor postrhinoplasty defects in appropriate patients. PMID:27975025

Realistic 3-D models of the human nasal passages were developed pre and post virtual uncinectomy and Middle Meatal Antrostomy. A 3-D computational domain was constructed by a series of coronal CT scan images from a healthy subject. Then a virtual uncinectomy intervention and maxillary antrostomy were performed on the left nasal passage by removing the uncinate process and exposing the maxillary sinus antrum. For several breathing rates corresponding to low or moderate activities, the airflows in the nasal passages were simulated numerically pre and post virtual routine maxillary sinus endoscopic surgery. The airflow distribution in the nasal airway, maxillary and frontal sinuses were analyzed and compared between pre and post surgery cases. A Lagrangian trajectory analysis approach was used for evaluating the path and deposition of microparticles in the nasal passages and maxillary sinuses. A diffusion model was used for nanoparticle transport and deposition analysis. The deposition rate of the inhaled micro and nanoparticles in the sinuses were evaluated and compared for pre and post operation conditions. The results showed that after maxillary sinus endoscopic surgery, the inhaled nano and microparticles can easily enter this sinus due to penetration of the airflow into the sinus cavity. This was in contrast to the preoperative condition in which almost no particles entered the sinuses. These results could be of importance for a better understanding of the effect of sinus endoscopic surgery on patient exposure to particulate pollution and inhalation drug delivery. The significantly higher airflow rate and particle deposition in the sinus could be a reason for the discomfort reported by some patient after maxillary sinus endoscopic surgery.

Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) have been shown to suppress expression of periostin, a matricellular protein that is markedly elevated in nasal polyp tissue. The purpose of this study was to determine whether use of these antihypertensive agents affects the time to revision sinus surgery in patients with polyp regrowth. Case series with chart review. Academic medical center. Records were reviewed for 330 patients who underwent ≥2 operations for chronic sinusitis with nasal polyps from April 1987 through August 2015. The time between surgical interventions was compared with patient demographics and clinical characteristics, including use of ACEIs and ARBs. Sixty patients were taking ACEIs or ARBs during the study period, of which 32 had concurrent asthma. The mean interval between polyp operations was 61.0 ± 45.2 months (range, 2-228.6 months). Among patients with asthma (n = 197), the mean time to revision surgery was prolonged by >2 years for those taking ACEIs or ARBs (81.0 vs 54.5 months, P = .006). A similar impact on time to revision surgery was not observed for nonasthmatics taking these medications (61.0 vs 65.2 months, P = .655). Use of ACEIs and ARBs is associated with an increased time to revision sinus surgery among patients with concurrent nasal polyps and asthma. A possible mechanism of this observed effect is suppression of periostin expression through inhibition of the angiotensin pathway. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

Turbinate reduction surgery may be indicated for inferior turbinate enlargement when conservative treatment fails. The aim of this study was to evaluate the effects of inferior turbinate surgery on nasal aerodynamics using computational fluid dynamics (CFD) simulations. CFD simulations were performed for the normal nose, enlarged inferior turbinate and following three surgical procedures: (1) resection of the lower third free edge of the inferior turbinate, (2) excision of the head of the inferior turbinate and (3) radical inferior turbinate resection. The models were constructed from MRI scans of a healthy human subject and a turbulent flow model was used for the numerical simulation. The consequences of the three turbinate surgeries were compared with originally healthy nasal model as well as the one with severe nasal obstruction. In the normal nose, the bulk of streamlines traversed the common meatus adjacent to the inferior and middle turbinate in a relatively vortex free flow. When the inferior turbinate was enlarged, the streamlines were directed superiorly at higher velocity and increased wall shear stress in the nasopharynx. Of the three surgical techniques simulated, wall shear stress and intranasal pressures achieved near-normal levels after resection of the lower third. In addition, airflow streamlines and turbulence improved although it did not return to normal conditions. As expected, radical turbinate resection resulted in intra-nasal aerodynamics of atrophic rhinitis demonstrated in previous CFD studies. There is little evidence that inspired air is appropriately conditioned following radical turbinate surgery. Partial reduction of the hypertropic turbinate results in improved nasal aerodynamics, which was most evident following resection of the lower third. The results were based on a single individual and cannot be generalised without similar studies in other subjects.

Nasal polyposis is an invalidating disease which develops through chronic inflammation which leads to tissue oedema and eventually polyps. Treatment is aimed at eliminating polyps, resolving rhinitis symptoms, re-establishing nasal breathing and olfaction and preventing recurrence. The pathogenesis can be explained, in part, by degranulation of mast cells and release of mediators attracting eosinophils which, in turn, can cause tissue damage and oedema. Neurovascular reflexes and factors related to the complex anatomy of ethmoidal labyrinth may be responsible for the onset and persistence of oedema. This would offer a rationale to treatments modifying ethmoid anatomy and blocking neurovascular reflexes in the management of nasal polyposis. The advent of microsurgery and of diagnostic and operative endoscopy has led, over the last twenty years, to earlier detection and to less traumatic and more precise surgical treatment of nasal polyps. With these techniques resection of parasympathetic innervation is also possible, which is in keeping with the proposed rationale and cannot be easily achieved by conventional surgery. To evaluate the impact of this resection on the management of nasal polyposis a review of data has been made in a series of patients with diagnosis of nasal polyposis established by clinical examination, resistant to pharmacological therapy and treated between 1983 and 1998 at the Oto-Neuro-Ophthalmology Department of Florence University (Italy). Patients were treated by conventional surgery (386 cases), by microsurgery without resection of the parasympathetic component of the vidian nerve (97 cases), or by microsurgery with resection of this latter component (94 cases). The rate of recurrence and of major post-operative complications, respectively, were: 39.9% and 4.4% for patients treated by conventional surgery; 37.1% and 6.2% with microsurgery without resection of parasympathetic innervation; and 25.5% and 2.1% with resection of this innervation

Some surgical procedures are rarely done on an outpatient basis. The primary objective of this study was to assess the safety of outpatient surgical shoulder stabilisation using the Latarjet procedure. The Latarjet procedure is safe when performed on an outpatient basis provided the patients are managed according to a specifically designed programme starting at the decision to undergo surgery and ending at the end of the early postoperative period. Consecutive patients with unidirectional anterior shoulder instability managed in 2013-2014 by primary open, minimally invasive surgery involving coracoid process transfer as described by Latarjet was included prospectively. One of the surgeons routinely offered outpatient surgery to patients who met none of the usual exclusion criteria (age>60years, ASA 3-4, and long distance from home to hospital). Standardised protocols were applied for anaesthesia and analgesia. The primary evaluation criterion was failure of the admission modality, defined as inpatient admission of a patient after outpatient surgery either without prior discharge or within 1week after discharge. Secondary evaluation criteria were early postoperative symptoms and functional outcomes after at least 1year. All self-reported criteria were entered online by the patients. Of 46 included patients, 17 had outpatient surgery and 29 inpatient surgery. There were 41 males and 5 females, with a mean age of 25.3±6.4years. No significant baseline differences were found between the two groups. None of the outpatients required inpatient admission or readmission. No postoperative complications were recorded. After a mean follow-up of 18.5±5.2months, the two groups showed no significant differences for return to sports, apprehension, avoidance behaviours, or functional outcomes. Most patients were satisfied with their management and outcomes. No serious adverse events were recorded in this first French prospective evaluation of the safety of open, minimally

Children's coping self-statements, levels of anxiety, degree of behavioral adjustment, as well as levels of maternal state anxiety and parenting style, and demographic variables were used to predict the reactions of 61 children to elective day surgery. Results indicated that elective day surgery was not psychologically traumatic for most children. However, the use of negative self-statements and both low and high maternal anxiety were found to be related to increased anxiety of the children experiencing elective day surgery.

Although medical intervention is the first option for treatment of nasal polyps, surgery is still a therapeutic option for symptomatic cases that do not respond or partially respond to medical intervention. However, there is a need for high-level evidence for the preoperative use of steroids in nasal polyposis surgery. We aimed to assess the perioperative effect of preoperative use of oral prednisolone for advanced-stage diffuse nasal polyposis. Prospective, double-blind, randomized, placebo-controlled study. A visual analog scale (VAS) was evaluated for smell, nasal discharge, nasal obstruction, facial pressure, headache, butanol smell threshold, and peak nasal inspiratory flow (PNIF) before and after the use of study drug. Perioperative bleeding volume, visibility of operative field, operative time, hospital stay, and complication rate were also evaluated. The improvement in the corticosteroid group (CG) in the VAS scores, butanol thresholds, and PNIF values showed statistically significant differences compared to the placebo group (PG) (P < .05). The perioperative bleeding volume, visibility score, operative time, and hospital stay for CG/PG were 141 mL/384 mL, 2.4/3.4, 61 min/71.6 min, and 1.1 day/1.8 day, respectively (P < .05). The difference between the complication rates for the two groups did not show any statistically significant difference (P = .214). Preoperative administration of systemic corticosteroids improves the perioperative visibility by reducing blood loss and shortens the operation time. We recommend the use of preoperative corticosteroid for the safety of the patients. The optimum dose and duration have not been established and require further studies. 1b. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

In this study we utilized computational fluid dynamic (CFD) techniques to construct a numerical simulation of nasal cavity airflow pre and post virtual functional endoscopic surgery (FESS). A healthy subject was selected, and CFD techniques were then applied to construct an anatomically and proportionally accurate three-dimensional nasal model based on nasal CT scans. A virtual FESS intervention was performed numerically on the normal nasal model using Fluent software. Navier-Stokes and continuity equations were used to calculate and compare airflow, velocity, distribution and pressure in both the pre and post FESS models. In the post-FESS model, there was an increase in airflow distribution in the maxillary, ethmoid and sphenoid sinuses, and a 13% increase through the area connecting the middle meatus and the surgically opened ethmoid. There was a gradual decrease in nasal resistance in the posterior ethmoid sinus region following FESS. These findings highlight the potential of this technique as a powerful preoperative assessment tool to aid clinical decision-making.

We report the case of a 63-year-old patient admitted to the ICU for an acute respiratory failure one week after an outpatient cataract surgery that revealed a nemaline rod myopathy. We present this rare myopathy whose particularities are its aetiology, which can be inherited, mostly with a congenital onset, or sporadic, and the variability of the age at presentation. We discuss the exceptional onset of severe unknown underlying diseases in the context of outpatient surgery. Copyright © 2012 Société française d’anesthésie et de réanimation (Sfar).

Objectives To investigate bacterial flora of clinically healthy conjunctiva and nasal cavity among patients prior to refractive surgery, as well as the characteristics of patients with methicillin-resistant Staphylococcus aureus (MRSA) colonisation. Design Observational and cross-sectional study. Setting A single-centre study in Japan. Participants 120 consecutive patients pre-refractive surgery. Primary and secondary outcome measures methods Samples were obtained from the right conjunctival sac and the nasal cavity of 120 consecutive patients prior to refractive surgery and were then measured for the levels of the minimum inhibitory concentration (MIC) of antibiotics. Patients were interviewed regarding their occupation, family living situation and any personal history of atopic dermatitis, asthma, smoking or contact lens wear. Results Propionibacterium acnes (P. acnes) (32.5%) and Staphylococcus epidermidis (4.2%) were detected from the conjunctival sac. S. epidermidis was the most commonly isolated (68.3%) in the nasal cavity. Of the 30 patients (25.0%) with colonisation by S. aureus, 2 patients, both of whom were healthcare workers with atopic dermatitis, were found to be positive for MRSA in the nasal cavity. A history of contact lens wear, asthma or smoking, as well as patient gender and age, was not associated with MRSA colonisation. Conclusions There were only 2 patients who were colonised with MRSA, both of whom were healthcare workers with atopic dermatitis. P. acnes was predominantly found in the conjunctival sac. Further study is needed to investigate the involvement between nasal and conjunctival flora, and risk factors for infectious complications. PMID:27160843

Background: The proportion of outpatient surgeries performed in physician offices has been increasing over time, raising concern about the impact on outcomes. Objective: To use a private insurance claims database to compare 7-day and 30-day hospitalization rates following relatively complex outpatient surgical procedures across physician offices, freestanding ambulatory surgery centers (ASCs), and hospital outpatient departments (HOPDs). Methods: A multivariable logistic regression model was used to compare the risk-adjusted probability of hospitalization among patients after any of the 88 study outpatient procedures at physician offices, ASCs, and HOPDs over 2008-2012 in Florida. Results: Risk-adjusted hospitalization rates were higher following procedures performed in physician offices compared with ASCs for all procedures grouped together, for most procedures grouped by type, and for many individual procedures. Conclusions: Hospitalizations following surgery were more likely for procedures performed in physician offices compared with ASCs, which highlights the need for ongoing research on the safety and efficacy of office-based surgery.

There has been a dramatic decline in the number of orthognathic surgery cases over the past 15 to 20 years. This decrease is a result of several compounding factors including decreasing coverage by major medical insurance companies and increasing health care costs. The difficulty associated with making orthognathic surgery financially practical has turned the interest of many oral and maxillofacial surgeons away from orthognathic procedures. The combination of these factors has resulted in decreased availability of surgeons participating in the correction of dentofacial deformities and has forced orthodontists and patients, without surgical correction as an option, to settle for less-than-ideal treatment results. To reverse this trend and make surgery more affordable and available, surgeons must work to make surgical treatment more acceptable to patients. This can be accomplished in several ways. First, the oral and maxillofacial surgery profession must reinforce the importance and value of orthognathic surgery to insurance providers, patients, and referring clinicians, as well as to surgeons within our own specialty. Alternative methods for providing high-quality surgical services at a reasonable cost must be explored including providing options for cost-effective outpatient surgical care, making better arrangements for financial assistance, and exploring options to obtain coverage from third-party providers. Outpatient surgery in facilities that can substantially reduce cost can be an effective way of providing quality treatment that is affordable to patients. Efficient, safe, and effective outpatient orthognathic surgery will help patients benefit from this valuable service.

Objectives To identify the incidence and the risk factors of emergence agitation in adults undergoing general anesthesia for nasal surgery. Methods We retrospectively examined 792 patients aged ≥18 years who underwent general anesthesia for elective nasal surgery between July 2012 and August 2013. Patients in the postanesthesia care unit with a Richmond Agitation Sedation Scale≥+1 at any time were considered to have emergence agitation. Results The overall incidence of emergence agitation is 22.2%. From multivariate regression analysis, the following six variables were found to be significantly associated with emergence agitation (P<0.05): younger age, recent smoking, sevoflurane anesthesia, postoperative pain on the numerical rating scale (NRS)≥5, presence of a tracheal tube, and presence of a urinary catheter. Presence of a tracheal tube was the greatest risk factor, increasing the risk of developing emergence agitation by approximately fivefold (odds ratio, 5.448; 95% confidence interval, 2.973 to 9.982). Younger age was also a strong risk factor (odds ratio, 0.975 for each 1-year increase; 95% confidence interval, 0.964 to 0.987). Current smoking, sevoflurane anesthesia, postoperative pain of NRS≥5, and the presence of a urinary catheter nearly doubled the risk of emergence agitation. Conclusion Emergence agitation following general anesthesia is a common complication in adult nasal surgery patients. To reduce the occurrence and consequences of agitation episodes, elimination of the associated risk factors is necessary, especially in at-risk patients. PMID:25729495

The number of outpatient orthopedic surgeries performed within North America continues to increase. The impact of this change in services on patient outcomes is largely unknown. The objective of this review is to compare patient outcomes and associated costs for outpatient orthopedic surgeries traditionally performed in hospital to inpatient surgeries, as well as to summarize the eligibility and preoperative education requirements for outpatient orthopedic surgery in North America. We performed a systematic review of Medline, Pubmed and Embase databases for articles comparing the clinical and economic impact of outpatient orthopedic surgical procedures versus inpatient procedures in North America. We reported on requirements for inpatient versus outpatient care, preoperative education requirements, complications and patient outcomes, patient satisfaction, and when available total mean costs. Nine studies met the inclusion criteria for this review. Eligibility requirements for outpatient orthopedic surgery within the included studies varied, but generally included: patient consent, a caregiver at home following surgery, close proximity to an outpatient center, and no history of serious medical problems. Preoperative education programs were not always compulsory and practices varied between outpatient centers. All of the reviewed studies reported that outpatient surgeries had similar or improved level of pain and rates of nausea. Outpatients reported increased satisfaction with the care they received. As expected, outpatient procedures were less expensive than inpatient procedures. This review found that outpatient procedures in North America appear to be less expensive and safe alternatives to inpatient care for patients who are at lower risk for complications and procedures that do not necessarily require close hospital level care monitoring following same day surgery.

Third molar surgery in the oral and maxillofacial surgery office has been a predictable model for evaluating the efficacy of sedatives and analgesics. In this setting, butorphanol plus diazepam and fentanyl plus diazepam were compared for surgical effectiveness and postoperative recovery. The comparison of butorphanol to a known sedative combination was clinically very satisfactory. It appears from this data that butorphanol has a pharmacologic place in outpatient conscious sedation.

The goal of this article was to analyze possibilities of the vitreoretinal surgery under the outpatient conditions and to set its limitations. During the period January 1st-September 30th, 2004, there were performed 95 operations of 78 eyes in 77 patients. Number of men and women was practically equal; the age ranged 17-86 years (average 62.6 years). We operated on mostly the retinal detachment. These as well as other procedures, including also the extreme surgery with relaxing retinectomy, extraction of the subretinal tractions and membranes, silicone oil implantation or extraction, or operations combined with the cataract surgery and intraocular lens implantation. Surgeries were performed under local anesthesia combined with analgesia and sedation introduced by anesthesiologist, who was always present and monitored the patient. Surgeries were performed by means of A.V.I. lens and Biom as well, with the assistance of a doctor, and later on, solely of a theatre nurse. The surgeon performed the operations by herself and long-term followed up the patients. The variety of vitreoretinal procedures did not differ from those performed at the departments of ophthalmology at university hospitals. The retinal detachment surgery was more often performed by means of cryosurgical procedure than pars plana vitrectomy undoubtedly because of early recognition of the beginning detachment. All vitreoretinal procedures may be performed on the outpatient basis. The only limiting factors are the physical condition of the patient and an acute ocular disease demanding urgent surgery in a facility with permanent service. Vitreoretinal surgery in outpatient facility performed under local anesthesia is well tolerated by the patients and the postoperative care under outpatient conditions is of equal quality as in inpatient facilities.

It is unclear whether chronic rhinosinusitis (CRS) patients with both nasal polyps and asthma have different quality of life (QOL) improvement after functional endoscopic sinus surgery (FESS). We aimed to determine whether CRS patients with asthma and nasal polyps had a greater QOL improvement after FESS compared to patients without asthma or polyps. This retrospective analysis included adult CRS patients who underwent FESS between 2007 and 2011. QOL was measured using the 22-item Sino-Nasal Outcome Test (SNOT-22). Variables collected included baseline demographics, clinical factors, SNOT-22 scores before FESS, and 1 month, 3 months, and 6 months post-FESS. Groups tested were asthma alone, polyps alone, asthma and polyps, and no asthma or polyps. Linear mixed-effects regression model was performed to calculate β-coefficients, which represent the adjusted mean QOL differences. Among the 376 patients included, 40.16% had both asthma and polyps (n = 151), 14.36% had asthma alone (n = 54), 19.45% had polyps alone (n = 75), and 25.53% had no asthma or polyps (n = 96). After adjusting for all factors, there were significantly more QOL improvements in patients with both asthma and nasal polyps from baseline to 1-month (β-coefficient = -10.05; 95% CI, -15.86 to -4.23; p = 0.001) and 3-month follow-up (β-coefficient = -8.27; 95% CI, -14.98 to -1.56; p = 0.016), and patients with asthma alone from baseline to 6-month follow-up (β-coefficient = -8.78; 95% CI, -17.45 to -0.11; p = 0.047), when compared to patients without asthma or nasal polyps. CRS patients with both asthma and nasal polyps or asthma alone experience a larger QOL benefit from FESS immediately after FESS compared to CRS patients without asthma or polyps. © 2014 ARS-AAOA, LLC.

This prospective, observational study explored the need for pain-related unscheduled contact with healthcare services after outpatient surgery. We hypothesised that 10% of outpatients would have pain-related unscheduled contact with healthcare services, and that the incidence would differ depending on the type of surgical procedure. In total, 905 patients who had undergone one of five common outpatient surgical procedures (knee or shoulder arthroscopy, surgical correction of hallux valgus, laparoscopic cholecystectomy or laparoscopic gynaecological procedures) completed an electronic questionnaire one week and eight weeks after surgery. Data from 732 patients (81%) were available for analysis. Within the first eight weeks after surgery, 150 patients (20.5%) had made unscheduled contact with healthcare professionals, in 247 cases due to pain that was most frequent in the first postoperative week. Risk factors were female sex, unemployment and laparoscopic cholecystectomy. The most frequent healthcare contact was with the general practitioner (46.4%), and the most frequent outcome was further information and guidance (41.2%). We have demonstrated that a minority of patients still needed to make contact with health services after outpatient surgery, most often due to inadequate pain management. This finding should be considered when planning postoperative monitoring and care, and developing postoperative patient education.
Background: Mediastinitis caused by methicillin-resistant Staphylococcus aureus (MRSA) is a serious complication after pediatric cardiac surgery. An outbreak of surgical site infections (SSIs) provided the motivation to implement SSI prevention measures in our institution. Methods: Subjects comprised 174 pediatric patients who underwent open-heart surgery after undergoing preoperative nasal culture screening. The incidence of SSIs and mediastinitis was compared between an early group, who underwent surgery before SSI measures (Group E, n = 73), and a recent group, who underwent surgery after these measures (Group R, n = 101), and factors contributing to the occurrence of mediastinitis were investigated. Results: The incidence of both SSIs and Mediastinitis has significantly decreased after SSI measures. With regard to factors that significantly affected mediastinitis, preoperative factors were “duration of preoperative hospitalization” and “preoperative MRSA colonization,” intraoperative factors were “Aristotle basic complexity score,” “operation time,” “cardiopulmonary bypass circuit volume” and “lowest rectal temperature.” And postoperative factor was “blood transfusion volume.” Patients whose preoperative nasal cultures were MRSA-positive suggested higher risk of MRSA mediastinitis. Conclusions: SSI prevention measures significantly reduced the occurrence of SSIs and mediastinitis. Preoperative MRSA colonization should be a serious risk factor for mediastinitis following pediatric cardiac surgeries. PMID:25641035

Corticosteroids are frequently used in a range of otorhinolaryngologic conditions due to their anti-inflammatory and antiedematous properties. In this meta-analysis, we aimed to assess the role of preoperative steroids for attenuating intraoperative bleeding during endoscopic sinus surgery among patients with nasal polyps. PubMed, SCOPUS, EMBASE, the Web of Science, and Cochrane database. Literature was screened from January 1980 to January 2016. Five articles comparing patients who were preoperatively administered steroids (steroid groups) with patients who received a placebo or no treatment (control group) were included for analysis, which encompassed intraoperative bleeding, endoscopic surgical field visibility, operative time, and side effects during endoscopic sinus surgery. Intraoperative bleeding and operative time during endoscopic sinus surgery in the steroid group were significantly reduced as compared with the control group. Additionally, the preoperative administration of steroids had a significant effect on improving endoscopic surgical field visibility during sinus surgery. There were no significant adverse effects reported in the enrolled studies. In subgroup analyses of these results, steroids showed similar effects on intraoperative bleeding regardless of administration type (topical or systemic). This study demonstrated that the preoperative administration of steroids in patients with nasal polyps could effectively reduce intraoperative bleeding. However, the duration of treatment and dosing standard require further investigation, and more trials need to be included. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

Zalpelon was compared with triazolam for oral sedation in a third molar surgery model using a double-blind crossover design. Factors such as anxiolysis, amnesia, and quality of sedation were assessed. Of the 14 participants who completed the study, zaleplon sedation was found to be similar to triazolam sedation in all regards except that recovery from zaleplon was more rapid. PMID:16596911

Objectives To assess biodegradable nasal packing effectiveness for improving postoperative symptoms and mucosal healing after endoscopic sinonasal surgery as compared with conventional/non-packing groups. Methods Relevant articles were searched on PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials. We included randomized controlled trials (RCTs) that compared biodegradable packings with conventional packings or no packing, reporting postoperative symptoms and/or mucosal healing outcomes. Results This review included 19 studies, of which 11 compared biodegradable packings with conventional packings. Meta-analysis found that biodegradable packings significantly improved postoperative symptoms: bleeding at removal, pain at removal, pain in situ, and nasal blockage. Mucosal healing outcomes were inconsistent within studies, with no data could be pooled. Eight studies compared biodegradable packings with non-packing group. Postoperative symptom data in this comparison could not be pooled: A protective or equal effect on postoperative bleeding was reported in different studies; no difference was reported in pain status and nasal blockage. As for mucosal healing, meta-analysis showed that two arms of comparison had similar effect on synechiae, edema, infection and granulation at each time point. Conclusion The limiting evidence suggests that biodegradable nasal packings are statistically better than conventional packings in postoperative symptoms, and probably comparable to non-packing group, as in this comparison we could not carry out meta-analysis. No beneficial or detrimental effect on postoperative mucosal healing could be determined based on existing evidence. PMID:25526585

There are concerns in Europe regarding the service provision and accessibility of multidisciplinary cardiac rehabilitation (MDCR) in general, and particularly in ambulatory settings. This paper analyses the utilization of outpatient MDCR and its determinants after cardiac revascularization or valve surgery in Belgium. Claims rehabilitation data for all patients discharged in 2007 after a percutaneous cardiac intervention or cardiac surgery were available from the Belgian Common Sickness Funds Agency. Logistic regressions were performed to identify patients demographic and socioeconomic characteristics associated with the uptake of outpatient MDCR during the year following the hospital discharge. A total of 29,021 patients were included. During the hospitalization for the cardiac procedure, 44% were offered inpatient MDCR. After discharge, only 15.6% followed at least one session of outpatient MDCR. The chance of attending outpatient MDCR was lower for female, disabled, and older patients, as well as unemployed patients. The absence of an authorized MDCR centre in the neighbourhood of the patient's residence decreased the chance of attending outpatient MDCR, while living in a neighbourhood with a high education and income level increased this probability. These results confirm the low rates of MDCR attendance found in a previous study performed by the European Association of Cardiovascular Prevention and Rehabilitation. The study shows specific patient groups that should be targeted in priority, i.e. women, elderly, unemployed patients, disabled persons, and patients with a low socioeconomic status.

The objective of the study was to elucidate the characteristics of spatial distribution of nasal polyps in the ostiomeatal complex (OMC) and the corresponding correlation with long-term quality of life in patients who underwent endoscopic sinus surgery. 107 patients with unilateral or bilateral nasal polyps who had undergone functional endoscopic sinus surgery from September 2009 to June 2010 were enrolled in this study. Distribution of nasal polyps in the study subjects was documented. Long-term quality of life assessment was carried out at 1-year after surgery by SNOT-20 analysis. Observation of a total of 214 sides of rhinal cavities revealed that nasal polyps were distributed inside the OMC at 573 sites out of the total 635 sites (90.2 %), and predominantly distributed at the middle turbinate, the ethmoid sinus, the middle meatus, the uncinate process, the maxillary sinus, and the ethmoid bulla and significantly differed from the nasal polyps which were found outside the OMC (P < 0.01). Statistical analysis indicated that pre-operative Sinonasal Outcome Test 20 (SNOT-20) scores and 1-year post-operative scores were statistically significant (P < 0.05). The score changes of the left maxillary sinus, both sides ethmoid bulla were significant, respectively (P < 0.05). Nasal polyps predominantly distribute in the OMC. The differences among the sites of nasal polyps do not significantly impact the long-term score for quality of life except for the maxillary sinus and ethmoid bulla.

To study the airflow velocity, trace, distribution, pressure, as well as the airflow exchange between the nasal cavity and paranasal sinuses in a computer simulation of nasal cavity pre and post virtual endoscopic sinus surgery (ESS). Computational fluid dynamics (CFD) technique was applied to construct an anatomically and proportionally accurate three-dimensional nasal model based on a healthy adult woman's nasal CT scans. A virtual ESS intervention was performed numerically on the normal nasal model using Fluent 6.1.22 software. Navier-Stokes and continuity equations were used to calculate and compare the airflow characteristics between pre and post ESS models. (1) After ESS flux in the common meatus decreased significantly. Flux in the middle meatus and the connected area of opened ethmoid sinus increased by 10% during stable inhalation and by 9% during exhalation. (2) Airflow velocity in the nasal sinus complex increased significantly after ESS. (3) After ESS airflow trace was significantly changed in the middle meatus. Wide-ranging vortices formed at the maxillary sinus, the connected area of ethmoid sinus and the sphenoid sinus. (4) Total nasal cavity resistance was decreased after ESS. (5) After ESS airflow exchange increased in the nasal sinuses, most markedly in the maxillary sinus. After ESS airflow velocity, flux and trace were altered. Airflow exchange increased in each nasal sinus, especially in the maxillary sinus.
Background. This prospective, controlled, parallel-group observational study investigated the efficacy of a spray containing hyaluronic acid and dexpanthenol to optimise regular treatment after nasal cavity surgery in 49 patients with chronic rhinosinusitis. Methods. The control group received standard therapy. Mucosal regeneration was determined using rhinoscopy sum score (RSS). Pre- and postoperative nasal patency was tested using anterior rhinomanometry. The participants were questioned about their symptoms. Results. Regarding all RSS parameters (dryness, dried nasal mucus, fibrin deposition, and obstruction), mucosal regeneration achieved good final results in both groups, tending to a better improvement through the spray application, without statistically significant differences during the whole assessment period, the mean values being 7.04, 5.00, 3.66, and 3.00 (intervention group) and 7.09, 5.14, 4.36, and 3.33 (control group). No statistically significant benefit was identified for nasal breathing, foreign body sensation, and average rhinomanometric volume flow, which improved by 12.31% (control group) and 11.24% (nasal spray group). Conclusion. The investigational product may have additional benefit on postoperative mucosal regeneration compared to standard cleaning procedures alone. However, no statistically significant advantage could be observed in this observational study. Double-blind, controlled studies with larger populations will be necessary to evaluate the efficacy of this treatment modality. PMID:25104962

To evaluate the influence of endoscopic sinus surgery on olfactory disorder caused by chronic sinusitis and nasal polyps, by testing the olfactory function of seventy-four patients before and after endoscopic sinus surgery,and evaluate the outcomes of olfactory dysfunction after endoscopic sinus surgery in patients with choinc rhinosinusitis and the related factors. The olfactory function of the seventy-four patients with chronic sinusitis and nasal polyps were tested by the T&T olfactory testing method at pre-operation and four weeks,twelve weeks, twenty-four weeks of post-operation. Patients were divided into two groups, according to whether combined with allergic rhinitis. Data were achieved by the scores of endoscopic appearances of Kennedy, and CT staging system of Lund-Mackey. Parallel processing standard endoscopic operation and processing specification during peri operation period. Analysing the degree of olfactory rehabilitation in chronic sinusitis and nasal polyps with allergic rhinitis. (1) Compared with the level of olfactory function, significant improvement was found at first month;however, the olfactory function level 4 weeks after operations was significantly statistically different with that 12 weeks and 24 weeks after operations; (2) Lund-Mackey sinus CT higher score is related to the worse degree of postoperative nasal olfactory rehabilitation (P < 0.05). (3) The higher scores of endoscopic appearances of Kennedy is related to the worse degree of postoperative nasal olfactory rehabilitation (P < 0.05). (4) Allergic rhinitis is one of the factors of olfactory rehabilitation in chronic rhinosinusitis with olfactory dysfunction olfactory rehabilitation, the olfactory rehabilitation of patients with allergic rhinitis is worse than that in the patients with no allergic rhinitis. (5) Course of disease is one of the factors of chronic rhinosinusitis with olfactory dysfunction olfactory rehabilitation. Longer the course of disease, worse the olfactory

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a highly prevalent disease of the nasal cavity and paranasal sinus, but its exact etiology is still unclear and remains a difficult-to-treat condition. Endoscopic sinus surgery (ESS) is an effective treatment for medically recalcitrant CRSwNP. There are independent variables that can predict surgical outcomes in patients with CRSwNP. To evaluate ESS efficacy in CRSwNP treatment and to establish prognostic factors for disease recurrence. Eighty-five patients with CRSwNP submitted to ESS, and a minimum follow-up of 9 months was selected. Patient demographics, occupational organic exposure (e.g., cotton, fuel gas, wood dust) and inorganic dust exposure (e.g., bleach, metals, cement), comorbidities, previous nasal surgeries, pre- and postoperative symptoms, ear, nose and throat examination findings, computed tomography results, and medical and surgical treatment information were collected from medical records. Statistical analysis was performed. All rhinologic symptoms improved after surgery, in a statistically significant way, with the best recovery rate for nasal obstruction and the worst for hyposmia. The major and minor complications rates were 1.2 and 15.3%, respectively. Disease recurrence occurred in 31% of the patient, but only 7% required surgical reintervention. Multivariate logistic regression analysis identified occupational dust exposure (p = 0.001) and non-immunoglobulin E (IgE) mediated asthma (p = 0.012) as independent predictive variables in CRSwNP recurrence, unlike the other tested variables: age, sex, IgE-mediated asthma, allergic rhinitis, smoking habits, nasal polyps endoscopic grade, Lund-Mackay score, and postoperative topical corticoid use. The adjusted logistic model presented a good discriminatory capacity with a receiver operating characteristic area under the curve of 0.82 (95% confidence interval, 0.73-0.91; p < 0.001). ESS proved to be an effective treatment in CRSwNP but with a

Intracranial air is a common finding after many neurosurgical procedures and trauma to the head. In patients requiring transport via air to reach a destination there is risk of expansion of the intracranial air and development of neurological complications. Though relatively uncommon after functional endoscopic sinus surgery (FESS), pneumocephalus may be encountered. We describe one of our patients in whom intracranial air was introduced during FESS. Following the procedure she required commercial air transportation from our center to her home. A 45-min commercial flight to the destination was safely completed without the patient experiencing any neurological sequellae. This case highlights the controversy surrounding air travel with pneumocephalus and provides an example of safe commercial air travel after diagnosis of post-FESS pneumocephalus.

Pain relief after surgery is an essential component of postoperative care. The purpose of this study was to compare the efficacy of intravenous acetaminophen and intravenous meperidine in pain relief after outpatient urological surgery. In a prospective, randomized, double-blind clinical trial, 100 outpatients of urological surgery were studied in two groups of acetaminophen (A) and meperidine (M). Patients in group A received 1g of acetaminophen in 100 mL saline within 15 minutes and patients in group M received a single intravenous injection of meperidine 0.5 mg/kg, 15 minutes prior to the end of operation. Postoperative pain was recorded using visual analog scale (VAS). Vital signs, nausea, vomiting, dizziness and respiratory depressions were compared between the two groups. Pain severity in patients treated with intravenous acetaminophen six hours after the operation within one-hour interval was significantly lower than meperidine group (P < 0.0001). Ninety patients in the meperidine group and five patients in the acetaminophen group required additional doses of analgesics. Nausea was significantly lower in acetaminophen group than meperidine group. Intravenous acetaminophen reduced pain following outpatient urological surgery more significantly than meperidine.

This prospective study assesses outcomes at 6 weeks and 7 months after radical ethmoid surgery in 65 patients with nasal polyposis using a new and detailed instrument, the DyNaChron questionnaire, which was filled in the day prior to surgery and at 6 weeks and 7 months after surgery at follow-up visits. Before surgery, the leading bothersome symptoms were olfactory disturbances (7.74 ± 2.81) and nasal obstruction (6.66 ± 2.28). After surgery (6th week and 7th month), there was a clear improvement of all symptoms including nasal obstruction, olfactory disturbances, anterior rhinorrhea, postnasal discharge, facial pain/headache and cough in comparison to baseline (p < 0.0001). Nasal obstruction was the most improved symptom (effect size of 2.24). At 7th post-operative month, the sense of smell continued to improve slightly. By contrast, the postnasal discharge score that was significantly improved at 6th post-operative week tended to worsen at 7 months (p = 0.0045). Before surgery, strong psychosocial impacts were observed in association with nasal obstruction and anterior rhinorrhea. The physical impacts of each symptom were proportionally correlated to the symptom score before and after surgery. The quality of life (QOL) related to each symptom was clearly better at 6 weeks and remained steady at 7 months after surgery. In conclusion, olfactory disorders and postnasal rhinorrhea were the main remaining symptoms after sinus surgery despite a global improvement of symptoms and quality of life. The earlier time point to stabilize QOL outcomes of endoscopic sinus surgery could be suggested at 6 weeks after surgery.

The rate of hospital-based acute care (defined as hospital transfer at discharge, emergency department [ED] visit, or subsequent inpatient hospital [IP] admission) after outpatient procedure is gaining momentum as a quality metric for ambulatory surgery. However, the incidence and reasons for hospital-based acute care after arthroscopic shoulder surgery are poorly understood. We studied adult patients who underwent outpatient arthroscopic shoulder procedures in New York State between 2011 and 2013 using the Healthcare Cost and Utilization Project database. ER visits and IP admissions within 7 days of surgery were identified by cross-matching 2 independent Healthcare Cost and Utilization Project databases. The final cohort included 103,476 subjects. We identified 1867 (1.80%, 95% confidence interval [CI], 1.72%-1.89%) events, and the majority of these encounters were ER visits (1643, or 1.59%, 95% CI, 1.51%-1.66%). Direct IP admission after discharged was uncommon (224, or 0.22%, 95% CI, 0.19%-0.24%). The most common reasons for seeking acute care were musculoskeletal pain (23.78% of all events). Nearly half of all events (43.49%) occurred on the day of surgery or on postoperative day 1. Operative time exceeding 2 hours was associated with higher odds of requiring acute care (odds ratio [OR], 1.28; 99% CI, 1.08-1.51). High-volume surgical centers (OR, 0.67; 99% CI, 0.58-0.78) and regional anesthesia (OR, 0.72; 99% CI, 0.56-0.92) were associated with lower odds of requiring acute care. The rate of hospital-based acute care after outpatient shoulder arthroscopy was low (1.80%). Complications driving acute care visits often occurred within 1 day of surgery. Many of the events were likely related to surgery and anesthesia (eg, inadequate analgesia), suggesting that anesthesiologists may play a central role in preventing acute care visits after surgery.

The evaluation of patient satisfaction provides important information about subjective quality indicators from the patient's perspective. In Germany, cataract surgery is mostly done ambulatory in a special surgery or in a hospital. This study examines if there are differences in global patient satisfaction of either outpatient setting and if there are different determinants of global satisfaction with regard to the outpatient settings. The survey comprises ambulatory operated cataract patients in Saxony between 2014 and 2015. A total of 4800 cataract patients sent back a standardized, written questionnaire. Regression analysis identified determinants of global patient satisfaction in both groups. The most influencing parameters for the global satisfaction were satisfaction with the treatment outcome, atmosphere and facilities in the surgery or hospital as well as the staff's level of kindness. Results of the conducted study show most identified determinants of patient satisfaction are associated with service variables, such as atmosphere and facilities in surgery or hospital and waiting time in surgery or hospital. These aspects should be focused on to improve patient satisfaction in cataract patients.

This study aimed to develop a multidisciplinary coded dataset standard for nasal surgery and to assess its impact on data accuracy. An audit of 528 patients undergoing septal and/or inferior turbinate surgery, rhinoplasty and/or septorhinoplasty, and nasal fracture surgery was undertaken. A total of 200 septoplasties, 109 septorhinoplasties, 57 complex septorhinoplasties and 116 nasal fractures were analysed. There were 76 (14.4 per cent) changes to the primary diagnosis. Septorhinoplasties were the most commonly amended procedures. The overall audit-related income change for nasal surgery was £8.78 per patient. Use of a multidisciplinary coded dataset standard revealed that nasal diagnoses were under-coded; a significant proportion of patients received more precise diagnoses following the audit. There was also significant under-coding of both morbidities and revision surgery. The multidisciplinary coded dataset standard approach can improve the accuracy of both data capture and information flow, and, thus, ultimately create a more reliable dataset for use outcomes and health planning.

Our purpose was to investigate the influences of nasal pretreatment with a mixed solution of epinephrine and lidocaine (E-L pretreatment) on the systemic hemodynamics and the mucosa of the inferior nasal concha, which is carried out for expansion of the nasal cavity and the prevention of mucosal injury before nasotracheal intubation. Subjects included 29 adult patients undergoing oral and maxillofacial surgery. This study consisted of 2 parts. In part 1 (n = 18), the effects of E-L pretreatment on the systemic hemodynamics were studied before (pre-Anesth group, n = 10) and after (post-Anesth group, n = 8) induction of anesthesia. Changes of the mucosal volume and the blood flow of the inferior nasal concha also were observed by optic bronchoscopy and noncontact type laser-Doppler flowmetry, respectively. In part 2 (n = 11), changes in the serum concentrations of epinephrine and lidocaine after the E-L pretreatment were determined by high performance liquid chromatography and enzyme immunoassay, respectively. The heart rate increased at 2 and 3 min after E-L pretreatment in pre-Anesth group (P < .05), but not in post-Anesth group. The cross section of the nasal cavity decreased from 66% to 42% (n = 8, P < .05). The mucosal blood flow decreased from 60 to 22 AU (n = 8, P < .01). The serum epinephrine concentration increased from 24 to 185 pg/mL. The E-L pretreatment provided characteristic evidence for useful expansion of the nasal cavity and for reduction of the nasal mucosal blood flow with less systemic hemodynamic effects, although further investigation is needed for the determination of the proper epinephrine concentration in E-L pretreatment.

Takotsubo cardiomyopathy (TC) is characterized by reversible left ventricular (LV) apical ballooning and no significant coronary artery stenosis. New variants of TC with localized wall motion abnormality or inversed pattern with hyperdynamic apex have been reported. We present the case of a 24-year-old female with atypical presentation of TC occurring in the setting of paranasal sinus surgery under local anaesthesia with post-surgical nasal packing. She did not demonstrate ST-segment elevation on electrocardiogram, but transient moderate LV systolic dysfunction and localized wall motion abnormality affecting basal to mid-ventricular anterior and anteroseptal wall. She rapidly and completely recovered without sequelae.

The purpose of this research is to determine the cause of nasal perforation symptoms and to predict post-operative function after nasal perforation repair surgery. A realistic three-dimensional (3D) model of the nose with a septal perforation was reconstructed using a computed tomography (CT) scan from a patient with nasal septal defect. The numerical simulation was carried out using ANSYS CFX V13.0. Pre- and post-operative models were compared by their velocity, pressure gradient (PG), wall shear (WS), shear strain rate (SSR) and turbulence kinetic energy in three plains. In the post-operative state, the crossflows had disappeared, and stream lines bound to the olfactory cleft area had appeared. After surgery, almost all of high-shear stress areas were disappeared comparing pre-operative model. In conclusion, the effects of surgery to correct nasal septal perforation were evaluated using a three-dimensional airflow evaluation. Following the surgery, crossflows disappeared, and WS, PG and SSR rate were decreased. A high WS.PG and SSR were suspected as causes of nasal perforation symptoms.

In the present study, the effects of endoscopic sphenoidotomy surgery on the flow patterns and deposition of micro-particles in the human nasal airway and sphenoid sinus were investigated. A realistic model of a human nasal passage including nasal cavity and paranasal sinuses was constructed using a series of CT scan images of a healthy subject. Then, a virtual sphenoidotomy by endoscopic sinus surgery was performed in the left nasal passage and sphenoid sinus. Transient airflow patterns pre- and post-surgery during a full breathing cycle (inhalation and exhalation) were simulated numerically under cyclic flow condition. The Lagrangian approach was used for evaluating the transport and deposition of inhaled micro-particles. An unsteady particle tracking was performed for the inhalation phase of the breathing cycle for the case that particles were continuously entering into the nasal airway. The total deposition pattern and sphenoid deposition fraction of micro-particles were evaluated and compared for pre- and post-surgery cases. The presented results show that sphenoidotomy increased the airflow into the sphenoid sinus, which led to increased deposition of micro-particles in this region. Particles up to 25 μm were able to penetrate into the sphenoid in the post-operation case, and the highest deposition in the sphenoid for the resting breathing rate occurred for 10 μm particles at about 1.5%.

Meta-analysis of both large outcome studies as well as cohort studies support the safety and efficacy of Endoscopic Sinus Surgery for Chronic Rhinosinusitis. The efficacy of endoscopic sinus surgery is demonstrated in the improvement of both disease-specific and generic QOL as well as objective measures. However, this must be interpreted together with a well-recognized long-term 15-20 % revision rate, seen more often in patients with ASA trias and cystic fibrosis as well as osteitis and previous surgery. The effect of surgery is higher in managing nasal obstruction (effect size 1.7) and less so hyposmia (effect size 0.8). Allergy has an additive role on the symptomatology of CRS; however, its role if any on the outcome of ESS for CRS is unclear. The concurrent presence of aspiring sensitivity and asthma is associated with increased disease burden and more revision surgeries. Improved phenotyping of CRS may lead in the future to better tailoring of surgical treatments.

Gabapentin and pregabalin has been shown to reduce postoperative pain effectively. In this meta-analysis, we aimed to assess the role of preoperative gabapentinoids for attenuating postoperative pain after nasal surgery in patients via a meta-analysis of the literature. PubMed, Scopus, and Cochrane Database. Literature was screened from inception to December 2015. Nine articles to compare the preoperative administered gabapentinoid (gabapentinoids groups) with a placebo or analgesics (control group) were included for analysis of the outcomes of interest, which included postoperative pain scores, analgesic intakes, or side effects, such as sedation, nausea and vomiting, blurred vision, operative bleeding, dizziness, and headache, during a 24-hour postoperative period. The pain score reported by the physician and need for analgesics during the first 24 hours, postoperatively, in the gabapentinoids group significantly reduced compared with the control. Additionally, the gabapentinoids had no significant effect on the incidences of side effects except blurred vision compared with the control during the 24 hours postoperatively. In the subgroup analyses of these results according to operation type, these subgroups showed similar effects on reducing postoperative pain and adverse effects. Preoperative gabapentinoids could attenuate postoperative pain without significant adverse effects in patients who undergo nasal surgery. However, blurred vision may be a handicap that requires consideration for use and education for patients. Further clinical trials will be of help in supporting the results of this study.

The objective of this investigation was to evaluate the practice of spinal anaesthesia among French anaesthetists in inpatient and outpatient settings. A questionnaire was sent to members of the French Association of Anaesthetists involved in regional anaesthesia during the first 4months of 2015. The questionnaire included items on the practice of spinal anaesthesia (type of needle, local anaesthetic available, puncture and disinfection techniques, etc.) and on the anaesthetic techniques usually used in 5 surgical situations eligible for outpatient surgery (knee arthroscopy, inguinal hernia, transobturator tape, haemorrhoids, varicose veins in the lower limbs). Responses from 703 anaesthesiologists were analysed. Spinal anaesthesia was usually performed in a sitting position (76%) using a Whitacre needle (60%) with a 25 G (57%) diameter. Ultrasound before puncture was reported in 26% of cases due to obesity or spinal abnormalities. Among the 5 surgical situations eligible for outpatient spinal anaesthesia, the technique was typically proposed in 29-49% of cases. Bupivacaine was the most used local anaesthetic. Concerns over delays in attaining readiness for hospital discharge, urine retention, operation length, and surgeon's preference were the main reasons for choosing another anaesthetic technique in these situations. New local anaesthetics are beginning to be used for outpatient spinal anaesthesia due to their interesting pharmacodynamic profile in this context. This study will provide a basis for evaluating future changes in practice. Copyright © 2016 Société française d'anesthésie et de réanimation (Sfar). Published by Elsevier Masson SAS.

In this study, we aimed to clarify the prognostic factors affecting the ethmoid condition during a long-term follow-up after endoscopic sinus surgery in patients with chronic rhinosinusitis with nasal polyps (CRSwNP). Thirty-six patients with CRSwNP underwent surgery from December 2008 to February 2012. All surgeries were performed by one surgeon, and all patients were followed up for at least 2 years postoperatively. We investigated the association of postoperative endoscopic findings with clinical parameters, mucosal eosinophil count and mRNA expression of CCL11, IL-5, and IFN-gamma in nasal polyps. Seventeen patients (47.2%) had severe mucosal edema, and the patency of each sinus was not confirmed during the >2-year follow-up. The mucosal eosinophil count and two eosinophil-associated factors, namely the CCL11 and IL-5 mRNA levels, were higher in the severe mucosal edema group than in the control group. The severe mucosal edema group was divided into two subgroups: the steroid-responsive and -resistant groups. Five patients (13.9%) had frank polyp formation because the oral steroids were less effective. The mucosal eosinophil count was significantly different among the four groups, including the control group (p=0.001); however, the CCL11, IL-5, and IFN-gamma mRNA levels were not significantly different. Although the IL-5 mRNA level was not significantly different among the four groups, it tended to increase when the sinus condition worsened. In the severe mucosal edema group, a higher IL-5 mRNA level was associated with earlier severe mucosal edema in the ethmoid cavity. The IL-5 mRNA level is associated with the time of severe edema formation in the ethmoid cavity. This finding permits early intervention on the postoperative course and would prevent polyp recurrence. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

To evaluate whether an ophthalmologist-led, non-anesthesia-supported, limited monitoring pathway for phacoemulsification/intraocular lens cataract surgery, can be performed safely with only a medical emergency team providing support. Retrospective, observational, cohort study. All patients who underwent elective phacoemulsification/intraocular lens surgery under topical anesthesia in the ophthalmology outpatient unit between January 1, 2011, and December 31, 2012. Cataract surgery was performed by phacoemulsification under topical anesthesia. The intake process mainly embraced ophthalmic evaluation, obtaining a medical history, and proposing the procedure. A staff ophthalmologist performed the procedure assisted by 2 registered nurses in an independent outpatient clinic operating room within the hospital. The clinical pathway was without dedicated presence of or access to anesthesia service. Perioperative monitoring was limited to blood pressure and plethysmography preoperatively and intraoperatively. Patients were offered supportive care and instructed to avoid fasting and continue all their chronic medication. The primary outcome measure was the incidence of adverse events requiring medical emergency team (MET) interventions throughout the pathway. Secondary outcome measures were surgical ocular complication rates, use of oral sedatives, and reported reasons to perform the surgery in the classical operation room complex. Within the cataract pathway, 6961 cases (4347 patients) were eligible for analysis. Three MET interventions related to the phacoemulsification/intraocular lens pathway occurred in the 2-year study period, resulting in an intervention rate of 0.04%. None of the interventions was intraoperative. All 3 patients were diagnosed as vasovagal collapse and recuperated uneventfully. No hospital admittance was required. Eight other incidents occurred within the general ophthalmology outpatient unit population during the study period. Cataract surgery can

To study the effect of functional endoscopic sinus surgery (FESS) in patients with chronic rhinosinusitis (CRS) and nasal polyps (NP) with concomitant asthma. The study was designed to evaluate prospectively whether FESS can influence parameters of asthma in patients with CRS with nasal polyps. One hundred thirty seven patients were recruited from the ENT-Allergy and Panedoscopy Clinic of the ENT Department. All selected patients underwent medical therapy for CRS and NP for 12 weeks, and in case of no improvement, they proceeded to surgical treatment. They also underwent pre- and post-treatment subjective and objective measurements for CRS and asthma. In the study, 86 patients were finally evaluated who completed the protocol and were followed up for a period of 12 months. The patients showed statistically significant improvement of the objective measurements for asthma, from baseline to six and twelve months follow-up. No significant increase was found in the proportion of patients with well or very well overall asthma-control during the follow-up period. There was a clear improvement in the use of bronchodilators, oral steroids and need for hospitalization for asthma. Obviously, there is a link between CRS with NP and asthma. The data analysis of our study supports the hypothesis that FESS could have beneficial effect on both diseases improving objective and subjective measurements.

To investigate the classification, incidence and influential factors of severe complications occurred in endoscopic sinus surgery (ESS) and how to deal with them. One thousand and one hundred two patients with chronic sinusitis and nasal polyps treated by ESS were analyzed. Twenty-one patients had severe complications. The types of complication included intraorbital hematoma (n=3), medial rectus injury (n=2), blindness (n=1), intracranial, hematoma (n=1), cerebrospinal rhinorrhea (n=3), nasolacrimal duct injury (n=3), nasal septum perforation (n=2), hemorrhage (n=2), thrombosis in legs (n=2) and asthma (n=2). The total incidence of severe complications was 1.91% (21/1102), most of which were complications in orbit (0.54%) and cranium (0.36%). The extent of the lesion, the surgical history of the patients, the technique and experience of the surgeons were the most important influential factors to severe complications. Although there are many influential factors to severe complications in ESS, subjective factors are the more important, especial, the technique and the experience of the surgeon.

Cataract surgery is an ideal candidate for outpatient care. In 2013, in the Toulouse University Hospital, outpatient care rate for phacoemulsification was 75.8%. We conducted this study to identify the barriers that limit the development of outpatient cataract surgery in our establishment. A retrospective observational study was conducted. We included all patients who underwent phacoemulsification (Medical Act Code BFGA004) as a traditional inpatient in 2013. We excluded admissions for which the medical, anesthesia or nursing records, as well as scheduling sheets, were incomplete. Patients were classified according to the reason for inpatient hospitalization and the type of surgery: cataract as primary surgery or cataract as combined procedure. Two hundred and ninety-eight stays were included with a mean age of 66.8 ± 16.8 years, and a male/female ratio of 0.76. The indication for inpatient hospitalization was a social, surgical or anesthetic reason in the following respective proportions: 41, 34 and 8% of cases. Failure of ambulatory care represented 7% of cases. Social isolation represented 89% of social reasons. In a combined gesture, the reason was surgical in 89% of cases. Development of outpatient surgery requires the participation of all involved. Taking into account the social factors is an essential element for developing ambulatory surgery. Social isolation is a frequent situation requiring a societal response. With regard to surgical considerations, practice patterns must target outpatient combined procedures in particular.

To determine the effects on time, cost, and complication rates of integrating physician assistants (PAs) into the procedural components of an outpatient oral and maxillofacial surgery practice. This is a prospective cohort study of patients from the Department of Plastic and Oral Surgery at Boston Children's Hospital who underwent removal of 4 impacted third molars with intravenous sedation in our outpatient facility. Patients were separated into the "no PA group" and PA group. Process maps were created to capture all activities from room preparation to patient discharge, and all activities were timed for each case. A time-driven activity-based costing method was used to calculate the average times and costs from the provider's perspective for each group. Complication rates were calculated during the periods for both groups. Descriptive statistics were calculated, and significance was set at P < .05. The total process time did not differ significantly between groups, but the average total procedure cost decreased by $75.08 after the introduction of PAs (P < .001). The time that the oral and maxillofacial surgeon was directly involved in the procedure decreased by an average of 19.2 minutes after the introduction of PAs (P < .001). No significant differences in postoperative complications were found. The addition of PAs into the procedural components of an outpatient oral and maxillofacial surgery practice resulted in decreased costs whereas complication rates remained constant. The increased availability of the oral and maxillofacial surgeon after the incorporation of PAs allows for more patients to be seen during a clinic session, which has the potential to further increase efficiency and revenue.

Venous thromboembolism is a serious surgical complication. Risk stratification does not reliably predict which patients will be affected, and anticoagulants introduce additional risks. The Doppler ultrasound scan is the definitive test for the detection of deep vein thrombosis. This prospective, controlled study was undertaken to determine the feasibility of Doppler ultrasound imaging as a screening tool for deep vein thromboses in plastic surgery outpatients. Doppler ultrasound screening was offered to 100 consecutive outpatients undergoing a variety of cosmetic plastic surgeries. Total intravenous anesthesia was administered by propofol infusion, and a laryngeal mask airway was inserted. SAFE (spontaneous breathing, avoid gas, face up, and extremities mobile) principles were observed. No patient received anticoagulants. Ultrasound scans were performed before surgery, 1 day after surgery, and approximately 1 week after surgery. Deep veins of the lower extremities, including the calf veins, were analyzed by compression, color Doppler imaging, and Doppler waveform analyses. Twenty-five control participants who did not undergo surgery were evaluated with ultrasonography. A survey was administered to all participants after the scans. No thromboses were detected in the outpatient or control group. Few survey respondents reported discomfort during the scan, and most indicated that ultrasound scans are a valuable screening tool for blood clots. Doppler ultrasound imaging of the lower extremities is a valuable, noninvasive method for detecting deep venous thromboses in plastic surgery outpatients. Additional study of this modality is warranted. LEVEL OF EVIDENCE 2: Diagnostic. © 2015 The American Society for Aesthetic Plastic Surgery, Inc.

Delphi Panel expert panel consensus and narrative literature review. To obtain expert consensus on best practices for patient selection and perioperative decision making for outpatient anterior cervical surgery (anterior cervical disc fusion (ACDF) and cervical total disc replacement (CTDR)). Spine surgery in ambulatory settings is becoming a preferred option for both patients and providers. The transition from traditional inpatient environments has been enabled by innovation in anesthesia protocols and surgical technique, as well as favorable economics. Studies have demonstrated that anterior cervical surgery (ACDF and CTDR) can be performed safely on an outpatient basis. However, practice guidelines and evidence-based protocols to inform best practices for the safe and efficient performance of these procedures in same-day, ambulatory settings are lacking. A panel of five neurosurgeons, three anesthesiologists, one orthopedic spine surgeon, and a registered nurse was convened to comprise a multidisciplinary expert panel. A three-round modified-Delphi method was used to generate best-practice statements. Predetermined consensus was set at 70% for each best-practice statement. A total of 94 consensus statements were reviewed by the panel. After three rounds of review, there was consensus for 83 best-practice statements, while 11 statements failed to achieve consensus. All statements within several perioperative categories (and subcategories) achieved consensus, including preoperative assessment (n = 8), home-care/follow-up (n = 2), second-stage recovery (n = 18), provider economics (n = 8), patient education (n = 14), discharge criteria (n = 4), and hypothermia prevention (n = 6). This study obtained expert-panel consensus on best practices for patient selection and perioperative decision making for outpatient anterior cervical surgery (ACDF/CTDR). Given a paucity of guidelines and a lack of established care pathways for ACDF/CTDR in same

Epidemiological and molecular data on community acquired methicillin resistant Staphylococcus aureus (CA-MRSA) are still scarce in both Egypt and Saudi Arabia. There is almost no data regarding methicillin resistant Staphylococcus aureus (MRSA) prevalence in both countries. This study was conducted to investigate the prevalence and molecular epidemiology of S. aureus and MRSA nasal carriage among outpatients attending primary health care centers in two big cities in both countries. A total of 206 nasal swabs were obtained, 103 swabs from each country. S. aureus isolates were characterized by antibiotic susceptibility, presence of mecA and PVL genes, SCCmec-typing and spa typing, the corresponding Multi locus sequence typing clonal complex was assigned for each spa type based on Ridom StaphType database. MRSA was detected in 32% of the Egyptian outpatients while it was found in 25% of the Saudi Arabian outpatients. All MRSA isolates belonged to SCCmec type V and IVa, where some isolates in Saudi Arabia remained nontypeable. Surprisingly PVL(+) isolates were low in frequency: 15% of MRSA Egyptian isolates and 12% of MRSA isolates in Saudi Arabia. Two novel spa types were detected t11839 in Egypt, and t11841 in Saudi Arabia. We found 8 spa types among 20 isolates from Egypt, and 12 spa types out of 15 isolates from Saudi Arabia. Only two spa types t008 and t223 coexisted in both countries. Four clonal complexes (CC5, CC8, CC22, and CC80) were identified in both Egypt and Saudi Arabia. However, the data collected lacked a representation of isolates from different parts of each country as only one health center from each country was included, it still partially illustrates the CA-MRSA situation in both countries. In conclusion a set of control measures is required to prevent further increase in MRSA prevalence. Copyright © 2014 Elsevier Editora Ltda. All rights reserved.

Context: Postoperative throat complaints such as postoperative sore throat (POST), dysphagia, and hoarseness frequently arises after tracheal intubation and throat packing for patient undergoing general anesthesia. This condition is very disturbing to patient. Avoiding POST is a major priority for these patients because preventing postoperative complications contributes to patient satisfaction. Aims: To describe and analyze the postoperative throat effects of nasopharyngeal packing and oropharyngeal packing in patients undergoing nasal surgery. Settings and Design: A randomized comparative study. Subjects and Methods: After obtaining approval of Ethical Committee 40 patients were included in study. After this patient were randomly allocated into two groups of 20 each. Group A - in which the oropharynx was packed and Group B - inwhich the nasopharynx was packed. General anesthesia were given and throat packing was done and patients were interviewed postoperatively for any throat complications such as sore throat, difficulty in swallowing (dysphagia), hoarseness of voice, throat irritation, and any other symptom pertaining to the study were noted and data were analyzed. Statistical Analysis Used: T-test to compare the age, while Chi-square test and Fisher's exact test were used to compare sex distribution, sore throat, dysphagia, hoarseness, and throat irritation. Results: Results showed statistically significant difference in incidence and severity of POST in Group A patients when compared to Group B patients to be more. Patients in Group A had a higher incidence of dysphagia when compared to their Group B counterparts. With respect to the incidence of hoarseness and throat irritation, there was no statistical significance between the groups. Conclusion: We concluded that the site of pharyngeal packing influences the incidence and severity of POST and as well as the incidence of dysphagia after general anesthesia. The use of nasopharyngeal packing in the patients

To evaluate and compare the face mask (FM) and oral mask (OM) ventilation techniques during anesthesia emergence regarding tidal volume, leak volume, and difficult mask ventilation (DMV) incidence. Prospective, randomized, crossover study. Operating room, training and research hospital. American Society of Anesthesiologists physical status I and II adult patients scheduled for nasal surgery. Patients in group FM-OM received FM ventilation first, followed by OM ventilation, and patients in group OM-FM received OM ventilation first, followed by FM ventilation, with spontaneous ventilation after deep extubation. The FM ventilation was applied with the 1-handed EC-clamp technique. The OM was placed only over the mouth, and the 1-handed EC-clamp technique was used again. A child's size FM was used for the OM ventilation technique, the mask was rotated, and the inferior part of the mask was placed toward the nose. The leak volume (MVleak), mean airway pressure (Pmean), and expired tidal volume (TVe) were assessed with each mask technique for 3 consecutive breaths. A mask ventilation grade ≥3 was considered DMV. DMV occurred more frequently during FM ventilation (75% with FM vs 8% with OM). In the FM-first sequence, the mean TVe was 249±61mL with the FM and 455±35mL with the OM (P=.0001), whereas in the OM-first sequence, it was 276±81mL with the FM and 409±37mL with the OM (P=.0001). Regardless of the order used, the OM technique significantly decreased the MVleak and increased the TVe when compared to the FM technique. During anesthesia emergence after nasal surgery the OM may offer an effective ventilation method as it decreases the incidence of DMV and the gas leak around the mask and provides higher tidal volume delivery compared with FM ventilation.

PURPOSE AND RESULTS: The aim of this prospective study was to determine the incidence of postoperative bleeding after oral surgery under local anaesthesia performed in outpatients with haemostatic disorders within a 5-year period (2003-2007). One hundred twenty one (70 males, 51 females) out of 2,056 outpatients with different haemostatic disorders (acquired or hereditary) were included in this study. The following data were recorded: medical history and general condition; medications; indication for the surgical procedure; specification of local anaesthesia; applied surgical techniques, considering the kind of haemostatic disorder; and peri- or postoperative bleeding complications. Postoperative bleeding was observed in 12 patients (9.9%). In three cases, inpatient treatment became necessary. The management of two patients with a haemostatic disorder (von Willebrand s disease and haemophilia A) is presented in short case reports. In a heterogeneous group of 121 outpatients with known haemostatic disorders, a combination of a few haemostatic agents with appropriate operative technique enables an effective wound management. In cases of failed local interventions after postoperative bleeding, further diagnostic investigations are required.

Nationally 62% of individuals in Ireland have internet access. Previous published work has suggested that internet use is higher among those with low back pain. We aimed to determine the levels of internet access and use amongst an elective spinal outpatient population and determine what characteristics influence these. We distributed a self-designed questionnaire to patients attending elective spinal outpatient clinics. Data including demographics, history of surgery, number of visits, level of satisfaction with previous consultations, access to the internet, possession of health insurance, and details regarding use of the internet to research one's spinal complaint were collected. 213 patients completed the questionnaire. 159 (75%) had access to the internet. Of this group 48 (23%) used the internet to research their spinal condition. Increasing age, higher education level, and possession of health insurance were all significantly associated with access to the internet (p < 0.05). A higher education level predicted greater internet use while possession of insurance weakly predicted non-use (p < 0.05). In our practice, internet access is consistent with national statistics and use is comparable to previous reports. Approximately, one quarter of outpatients will use the internet to research their spinal condition. Should we use this medium to disseminate information we need to be aware some groups may not have access.

Although the safety of topical nasal steroids is well established for nasal spray forms, data regarding the safety of steroid irrigations is limited. We studied the effect of long-term budesonide nasal irrigations (>6 months) on hypothalamic-pituitary-adrenal axis (HPAA) function and intraocular pressure (IOP) in patients post-endoscopic sinus surgery. This was retrospective case series. Adrenal function was assessed by using the high-dose cosyntropin stimulation test. A total of 48 patients were assessed, with a mean duration of budesonide irrigations of 22 months. Stimulated cortisol levels were abnormally low in 11 patients (23%). None reported to have symptoms of adrenal suppression. Three of 4 patients who repeated the study being off budesonide for at least 1 month returned to near normal levels. Logistic regression analysis revealed that concomitant use of both nasal steroid sprays and pulmonary steroid inhalers was significantly associated with HPAA suppression (p = 0.024). Patients with low stimulated cortisol levels were able to continue budesonide irrigations under the supervision of an endocrinologist without frank clinical manifestations of adrenal insufficiency. IOP was within normal limits in all patients. Long-term use of budesonide nasal irrigations is generally safe, but asymptomatic HPAA suppression may occur in selected patients. Concomitant use of both nasal steroid sprays and pulmonary steroid inhalers while using daily budesonide nasal irrigations is associated with an increased risk. Rhinologists should be alerted to the potential risks of long-term use of budesonide nasal irrigations, and monitoring for HPAA suppression may be warranted in patients receiving long-term budesonide irrigation therapy. © 2016 ARS-AAOA, LLC.

The authors examined the economic patterns of outpatient aesthetic and reconstructive plastic surgical procedures performed within an academic health center. For fiscal years 2003 and 2004, the University of Michigan Health System's accounting database was queried to identify all outpatient plastic surgery cases (aesthetic and reconstructive) from four surgical facilities. Total facility charges, cost, revenue, and margin were calculated for each case. Contribution margin (total revenue minus variable direct cost) was compared with total case time to determine average contribution margin per operating suite case minute for subsets of aesthetic and reconstructive procedures. A total of 3603 cases (3457 reconstructive and 146 aesthetic) were identified. Payer mix included Blue Cross (36.7 percent), health maintenance organization (28.7 percent), other commercial payers (17.4 percent), Medicare/Medicaid (13.5 percent), and self-pay (3.7 percent). The most profitable cases were reconstructive laser procedures ($66.20; n = 361), scar revision ($36.01; n = 25), and facial trauma ($32.17; n = 64). The least profitable were hand arthroplasty ($13.93; n = 35), arthroscopy ($17.25; n = 15), and breast reduction ($17.46; n = 210). Aesthetic procedures (n = 144) yielded a significantly higher contribution margin per case minute ($24.21) compared with reconstructive procedures ($22.28; n = 3093) (p = 0.01). Plastic surgical cases performed at dedicated ambulatory surgery centers ($28.60; n = 1477) yielded significantly higher contribution margin per case minute compared with those performed at hospital-based facilities ($25.58; n = 2123) (p < 0.01). Use of standardized accounting (contribution margin per case minute) can be a strategically effective method for determining the most profitable and appropriate case mix. Within academic health centers, aesthetic surgery can be a profitable enterprise; dedicated ambulatory surgery centers yield higher profitability.

This paper quantifies the registration and fusion display errors of augmented reality-based nasal endoscopic surgery (ARNES). We comparatively investigated the spatial calibration process for front-end endoscopy and redefined the accuracy level of a calibrated endoscope by using a calibration tool with improved structural reliability. We also studied how registration accuracy was combined with the number and distribution of the deployed fiducial points (FPs) for positioning and the measured registration time. A physically integrated ARNES prototype was customarily configured for performance evaluation in skull base tumor resection surgery with an innovative approach of dynamic endoscopic vision expansion. As advised by surgical experts in otolaryngology, we proposed a hierarchical rendering scheme to properly adapt the fused images with the required visual sensation. By constraining the rendered sight in a known depth and radius, the visual focus of the surgeon can be induced only on the anticipated critical anatomies and vessel structures to avoid misguidance. Furthermore, error analysis was conducted to examine the feasibility of hybrid optical tracking based on point cloud, which was proposed in our previous work as an in-surgery registration solution. Measured results indicated that the error of target registration for ARNES can be reduced to 0.77 ± 0.07 mm. For initial registration, our results suggest that a trade-off for a new minimal time of registration can be reached when the distribution of five FPs is considered. For in-surgery registration, our findings reveal that the intrinsic registration error is a major cause of performance loss. Rigid model and cadaver experiments confirmed that the scenic integration and display fluency of ARNES are smooth, as demonstrated by three clinical trials that surpassed practicality.

A considerable challenge arises when passage of an endotracheal tube between the teeth is impossible because of severe trismus and the presence of concomitant contraindications to nasotracheal intubation. We report a novel technique to circumvent the need for tracheostomy by using the retromolar space for oral fibreoptic intubation. A 50-yr-old female with a history of pharyngeal cancers treated with surgery and radiotherapy presented for right dacryocystorhinostomy. She had undergone left dacryocystorhinostomy after nasotracheal intubation one week earlier. This time, orotracheal intubation was requested since surgery would involve the right nostril and left nasal intubation might dislodge the recently placed nasolacrimal tube. Due to severe trismus, the patient's interincisor distance was only 9 mm, and it was impossible to pass a 6.0 mm endotracheal tube through that gap. A flexible bronchoscope loaded with a 6.0 mm tracheal tube was inserted through the retromolar space into the pharynx and maneuvered through the vocal cords for endotracheal intubation. The retromolar space is located between the last molar and the ascending ramus of the mandible. Even with complete mandibular occlusion, it is usually able to accommodate a 7.0 mm endotracheal tube. Despite its hidden location, it can be used successfully for orotracheal fibreoptic intubation. With practice, the expertise achieved in performing this technique will confer a much needed option for securing the airway in this challenging situation.

Background The conventional treatment of obesity presents unsatisfactory results on weight loss and its long-term sustainability, therefore bariatric surgery has been suggested as an effective therapy, determining sustainable long-term weight loss, reversal of components of cardiometabolic risk and improved quality and life expectancy. Aim To investigate the clinical component of the cardiometabolic risk in patients undergoing bariatric surgery assisted on outpatient basis. Methods The sample consisted of 47 patients with ages between 18 and 60 years, 72% females. Diabetes mellitus, hypertension, and dyslipidemia were prospectively evaluated by using the Assessment of Obesity-Related Co-morbidities scale. Results Occurred improvement in these co-morbidities within 12 months after surgery. Co-morbidities resolved were greater than those improved. Conclusion The study revealed that the Assessment of Obesity-Related Co-morbidities is a system that can be effectively used to quantify the degree of reduction of the severity of the cardiometabolic risk in response to bariatric surgery.

To evaluate the impact of intravenous midazolam dose on the duration of recovery room stay for patients undergoing outpatient third molar surgery. Using a retrospective cohort study design, a sample of patients undergoing outpatient third molar surgery under intravenous sedation at Mayo Clinic from 2010 to 2014 was identified. All patients underwent extraction of all 4 third molars during a single operative procedure and the age range was limited to 14 to 29 years. The primary predictor variable was the total dose of intravenous midazolam administered during sedation. The primary outcome variable was recovery room length of stay (LOS) after completion of surgery. Multiple covariates also abstracted included patient age, gender, American Society of Anesthesiologists (ASA) score, duration of surgical procedure, complexity of surgical procedure, types and dosages of all intravenous medications administered during sedation, and volume of crystalloid fluid administered perioperatively. Univariable and multivariable models were developed to evaluate associations between the primary predictor variable and covariates relative to the primary outcome variable. The study sample was composed of 2,610 patients. Mean age was 18.3 years (SD, 3.0 yr; range, 14 to 29 yr) and gender distribution was 52% female. Mean dosage of midazolam administered was 4.1 mg (SD, 1.1 mg; range, 0.5 to 10.0 mg). Variables predicting shorter LOS at multivariable analysis included older age (P < .001), male gender (P = .004), and administration of larger crystalloid fluid volumes (P < .001). Variables predicting longer LOS included higher ASA score (P < .001), administration of ketamine (P < .001), and administration of ketorolac (P < .001). The dose of midazolam administered during sedation was not found to be significantly associated with prolonged recovery room LOS in univariable or multivariable settings. Dosage of intravenous midazolam does not appear to significantly impact the

The purpose of this study was to explore the effectiveness of the aromatherapy product QueaseEASE (QE) for decreasing postdischarge nausea (PDN) in patients undergoing outpatient abdominal surgery. Prospective exploratory study. Informed Consent was obtained preoperatively from a convenience sample of adult patients scheduled for outpatient abdominal surgery procedures. Prior to discharge, subjects were instructed in the use of QE and given instructions on how to rate their nausea on a 0-10 scale. They recorded nausea scales > 0 any time they occurred for the next 24 hours, used the QE, and recorded their nausea scales 3 minutes later. A study nurse called subjects the next day to collect the information. The sample included 70 outpatients who underwent abdominal surgery. Twenty-five participants (36%) reported experiencing PDN and their concomitant use of QE. There was a significant difference in mean age of those reporting PDN (37 years) versus those without nausea (48 years, P = .004) as well as a significant difference in mean intravenous fluid intake during hospitalization of those reporting PDN (1,310 mL) versus those without nausea (1,511 mL, P = .04). The PDN group had more female participants (72% vs 42%, P = .02), more participants that were less than 50 years of age (84% vs 53%, P = .02), and received more opioids (100% vs 76%, P = .006) than the no nausea group. The 25 PDN participants reported 47 episodes of PDN in which they used QE. For all of the 47 PDN episodes experienced, participants reported a decrease in nausea scale (0 to 10) after the use of QE; for 22 (47%) of the PDN episodes experienced, a nausea scale of 0 after using QE was reported. The mean decrease in nausea scale for all 25 participants was 4.78 (±2.12) after using QE. This study found that the aromatherapy QE was an effective treatment of PDN in select same-day abdominal surgery patients. Copyright © 2015 American Society of PeriAnesthesia Nurses.

Background The association between early outpatient follow-up and 30-day readmission has not been evaluated in any surgical population. Our study characterizes the relationship between outpatient follow-up and early readmissions among surgical patients. Methods We queried the medical record at a large, tertiary care institution (July 2008-December 2012) to determine rates of 30-day outpatient follow-up and readmission for general or vascular surgical procedures. Results The majority of discharges for general (84% of 7552) and vascular (75% of 2362) surgery had a follow-up visit before readmission or within 30 days of discharge. General surgery patients who were not readmitted had high rates of follow-up (88%) and received follow-up at approximately 2-weeks post-discharge (median time 11 days after discharge). In contrast, readmitted general surgery patients received first follow-up at one week (a median time of 8 days); 49% had follow-up. Vascular surgery patients showed a similar trend. Over half of patients readmitted after follow-up were readmitted within 24 hours of their most recent outpatient visit. Conclusions Current routine follow-up does not occur early enough to detect adverse events and prevent readmission. Early outpatient care may prevent readmission in some patients, but often serves as a conduit for readmission among patients already experiencing complications. PMID:25239351

Determine whether transconjunctival local anesthesia using 2% lidocaine gel decreases pain perception in comparison with transcutaneous anesthesia in patients undergoing outpatient eyelid surgery. This is a randomized controlled clinical trial. This study approved by an institutional review board and adhered to the Declaration of Helsinki and the Health Insurance Portability and Accountability Act. A total of 120 patients undergoing bilateral upper or lower eyelid surgery were enlisted. Topical 2% lidocaine gel was administered to the palpebral conjunctiva for 1 minute, followed by a local transconjunctival injection. Local anesthetic was administered to the contralateral eyelid by a transcutaneous approach without use of topical anesthetic. Both injections were 1 ml of 1% lidocaine with epinephrine 1:100,000 on a 30-gauge needle. After each injection, patients rated the pain on a 0-to-10 visual analog scale. Patients were also asked for preference between the 2 sides. The mean pain scores were 2.33 (standard deviation 0.98) for the transconjunctival side and 3.42 (standard deviation 0.88) for the transcutaneous side. The reduction in pain scores for lidocaine gel-treated sides was statistically significant (p < 0.001) when controlling for side of intervention, upper versus lower eyelid procedures, sex of participants, and type of procedure. In addition, 85% of participants found the transconjunctival injection to be less painful than the transcutaneous (p < 0.001). Transconjunctival local anesthesia in conjunction with topical anesthesia with 2% lidocaine gel provides a clinically and statistically significant decrease in perceived pain when compared with transcutaneous anesthesia in patients undergoing outpatient eyelid surgery.

The problem with prepuce retraction is caused not only by its narrowing, called phimosis, but also frequently by the inner prepuce adhesion to glans. The spontaneous prepuce retraction is received in 80% cases of boys up to the age of two, whereas in remaining cases, after the age of two it is necessary to take up the medical treatment. The purpose of the research was to estimate the effectiveness of conservative therapy using steroid ointments which was undertaken in boys referred to Outpatient Paediatric Surgery Centre with recognition of phimosis. Cases of 315 boys referred to Outpatient Paediatric Surgery Centre due to phimosis were analyzed between April 2004 and May 2007. At the first appointment the boys were divided into 3 main groups: I--children with foreskin adhesion without visible stenosis (near 20%), who had the prepuce adhesion released in a local anaesthetic with Emla cream; II--children with narrowed foreskin (phimosis) who were treated with the use of conservative therapy by means of topical steroids (about 70%); III--children with stenosed prepuce (phimosis) developed to a large extent, who were immediately qualified to a surgery therapy without trying the conservative therapy (near 10%). Among all patients about 1/5 needed the prepuce adhesion releasing with the use of Emla ointment only. High efficiency of conservative treatment with topical steroids was revealed both in primary and acquired phimosis. Reduction of the therapy time of children treated with topical steroids because of primary phimosis in relation to those treated surgically was taken into account. Conservative treatment of phimosis is highly effective and safe method which may also be an initial stage to operative treatment or to cure scarring after surgical treatment as well.

To study sevoflurane inhalation general anesthesia using the laryngeal mask airway (LMA) and nasal endotracheal (ET) intubation to maintain the airway in pediatric day-case dental surgery. A total of 171 children aged 2 to 7 years received elective day-case dental surgical procedure under general anesthesia. Children were randomly grouped into LMA groups (L) and nasal ET intubation group (N). In L groups, LMA was inserted after induction of anesthesia using 8% sevoflurane and were allowed to breathe spontaneously. Rocuronium and remifentanil were given intravenously during 8% sevoflurane induction by nasal ET intubation in the N group . The time of anesthetic induction, maintenance, recovery, surgical access, and bispectral index score were recorded. Postoperative nausea and vomiting and the incidence of adverse events during induction and recovery period were also recorded. The insertion time of LMA was significantly shorter than nasal ET (P < 0.05). The incidence of airway complications, the surgeons' access, and bispectral index were not different between the 2 groups. However, recovery time was significantly shorter in group L (P < 0.05). The incidence of sore throat and postoperative nausea and vomiting (P < 0.01) were much less in group L as well. Sevoflurane inhalation anesthesia through LMA is a safe and reliable method for pediatric day-case dental surgery.

The study aimed to determine the natural history of Staphylococcus aureus nasal colonization in hemodialysis outpatients. Surveillance cultures were taken from patients presenting for hemodialysis or routine care to identify S. aureus nasal carriers. A prospective cohort study was performed to identify risks for persistent colonization. Detailed microbiologic and molecular studies of colonizing isolates were performed. Only 23/145 (15.9%) dialysis patients were persistently colonized, and only HIV-positive status was associated with persistence (P = 0.05). Prior hospitalization was the only risk factor for methicillin-resistant S. aureus carriage (OR 2.5, P = 0.03). In isolates from patients with ≤42 days of vancomycin exposure, vancomycin minimum bactericidal concentrations (MBCs) increased with duration of exposure. Among dialysis patients, S. aureus colonization was limited and transient; only HIV status was associated with persistence. Nevertheless, duration of vancomycin exposure was associated with increasing vancomycin MBCs. Vancomycin exposure in S. aureus carriers may be involved in increasing resistance. PMID:21334154

Mental health conditions, including psychiatric and substance abuse diagnoses, have been associated with poor postoperative outcomes, but no studies have quantified the relationship to date. The authors examine the association between mental health conditions and immediate postoperative outcomes as defined by further hospital-based acute care within 30 days of surgery. California State Ambulatory Surgery, Inpatient, and Emergency Department Databases were used to identify all adult patients undergoing outpatient cosmetic plastic surgery between January 2007 and October 2011. Patients were subgrouped by the presence of mental health or substance abuse conditions. Primary outcome was the need for hospital-based acute care (admission or emergency department visit) within 30 days after surgery. Multivariable logistic regression models compared outcomes between groups. Of 116,597 patients meeting inclusion criteria, 3.9% and 1.4% had either a psychiatric or substance abuse diagnosis, respectively. Adjusting for medical comorbidities, patients with psychiatric disorders more frequently required hospital-based acute care within 30 days postoperatively than those without mental illness diagnoses (11.1% vs 3.6%; adjusted odds ratio [AOR], 1.78 [95% confidence interval, 1.59-1.99]). This was true both for hospital admissions (3.5% vs 1.1%; AOR, 1.61 [1.32-1.95]) and emergency department visits (8.8% vs 2.7%; AOR, 1.88 [1.66-2.14]). The most common acute diagnoses were surgical in nature, including postoperative infection, hemorrhage, and hematoma; the median hospital admission charge was $35 637. Similar findings were noted among patients with a substance abuse diagnosis. Mental health conditions are independently associated with the need for more frequent hospital-based acute care following surgery, thus contributing to added costs of care. A patient's mental health should be preoperatively assessed and appropriately addressed before proceeding with any elective procedure

Soft tissue changes secondary to Maxillary orthognathic surgery are many fold. The alar flare is one among them, which affects the appearance of the patient. Cinch suture has been used to prevent alar flare; but the presence of anaesthetic tube hinders cinching. So, the study was aimed to assess an efficacy of modified nasal to oral tube switch technique for modified alar cinching to prevent alar flare after orthognathic and nasal corrective surgeries. Patients were randomly allocated in each group, who underwent modified alar base cinching with and without nasal to oral tube switch. Changes in alar base width, upper lip length was measured with Digital Vernier Caliper and nasolabial angle (Cotg-Sn-Ls) on lateral cephalogram at 1st, 3rd, 6th, and 12th months after surgery. The time taken and ease of tube switch were noted. The data obtained were tabulated and interpreted using a test of significance. Study results showed no statistical significant difference in perinasal soft changes among both groups. But tube switch appears to be beneficial to prevent alar flare. Modified alar base cinching was performed effectively in patients with a modified tube switch technique. It increased positive results in comparison with non-shift. The technique of tube switch used is effective in prevention of alar flare. Because of small sample size and limited period of follow up, our study suggests multi centre, randomized studies to know the technical difficulties of tube switch for cinching and aesthetic results with varying anaesthetist and the surgeon's experience.

Primary hyperhidrosis is a frequent dysfunctional disorder characterized by excessive sweating in amounts greater than required for physiological needs. Surgery remains the mainstay of treatment when there is no response to medical therapies. Traditionally, thoracoscopic sympathectomy is performed routinely by means of general anesthesia with endotracheal intubation. Here we report the least invasive management for hyperhidrosis surgery, a nonintubated bilateral single port thoracoscopic sympathectomy in the context of an outpatient program. PMID:26807412

Topical cooling with ice slush as an adjunct for myocardial protection during cardiac surgery has been shown to cause freezing injury of the phrenic nerves. This can cause diaphragmatic dysfunction and respiratory complications. Twenty (n=20) male patients between the ages of 40 and 60 years were equally randomised to undergo elective coronary artery bypass grafting (CABG) with either cold cardioplegic arrest with topical ice slush cooling or cold cardioplegic arrest without the use of ice slush. The sniff nasal inspiratory force (SNIF) was used to compare inspiratory muscle strength. There was no difference in the preoperative SNIF in the two randomised groups. In the immediate postoperative period, the ice slush group had worse SNIF (33.5±9.6cm H2O versus 47.8±12.2cm H2O; p=0.009). The pre-home discharge SNIF was still significantly lower for the ice slush group despite a noted improvement in SNIF recovery in both groups (38.3±10.6cm H2O versus 53.5±13.2cm H2O; p=0.011). Two patients in the ice slush group had left diaphragmatic dysfunction with none in the control group. The use of topical ice slush is associated with freezing injury of the phrenic nerves. This will adversely affect the inspiratory muscle force which may lead to respiratory complications after surgery.

Objective Assess whether the presence of mucosal eosinophilia correlates with surgical outcomes in patients with chronic rhinosinusitis. Study Design Prospective cohort Setting Tertiary medical center Subjects and Methods Adult patients with chronic rhinosinusitis were prospectively enrolled and demographic data and medical comorbidities recorded. Preoperative quality-of-life (QOL) was measured by the Chronic Sinusitis Survey (CSS), Rhinosinusitis Disability Index (RSDI), and Short Form-36 General Health Survey (SF-36). Sinus mucosal specimens were collected at the time of surgery and the degree of eosinophilia quantified. Postoperative QOL was measured and differences in QOL improvement were compared between those with and without eosinophilia. Results A total of 102 patients had both histopathologic and QOL outcome data available for review. Follow-up averaged 16.5 months. Patients with eosinophilia showed significantly less improvement in the RSDI total (17.9 vs 25.0; p=0.044), RSDI functional (5.7 vs 8.8; p=0.018), CSS medication (3.6 vs 17.3; p=0.013), SF-36 general health (0.6 vs 9.6; p=0.008), SF-36 physical role (16.1 vs 34.7; p=0.036), and SF-36 vitality (11.9 vs 21.2; p=0.034) scales than those without eosinophilia. The greatest improvement in QOL was seen in patients without eosinophilia or polyps and the least improvement seen in those with eosinophilia but without polyps. Conclusion The presence of mucosal eosinophilia at the time of surgery consistently predicted less improvement in both disease-specific and general QOL compared to those without eosinophilia. The impact of eosinophilia on outcomes was greatest for patients without nasal polyposis, a group which demonstrated the least improvement in QOL measures. PMID:20096225

Outpatient wound care plays an integral part in any plastic surgery practice. However, compliance with hand hygiene measures has shown to be low, due to skin irritation and lack of time. The objective of this trial was to determine whether single-use, long-acting antiseptics can be as effective as standard multiple-use hand hygiene methods in an outpatient surgical setting. A prospective, randomized controlled trial was performed in the authors' outpatient plastic surgery clinic at Rutgers New Jersey Medical School, Newark, NJ to compare the efficacy of an ethyl alcohol-based sanitizer (Avagard D Instant Hand Aniseptic, 3M Health Care, St. Paul, MN), a benzalkonium chloride-based sanitizer (Soft & Shield, Bioderm Technologies, Inc, Trenton, NJ, distributed by NAPP Technologies, Hackensack, NJ ), and soap and- water handwashing. Subjects included clinic personnel, who were followed throughout the course of a 3-hour clinic session with hourly hand bacterial counts taken. During the course of the trial, 95 subjects completed the clinic session utilizing 1 of the hand hygiene methods (36 ethyl alcohol-based sanitizer, 38 benzalkonium chloride-based sanitizer, and 21 soap-and-water handwashing). There was no difference between hand bacterial counts using the different methods at 4 hourly time points (P greater than 0.05). Hand bacterial counts increased significantly over the 3-hour clinic session with the ethyl alcohol-based sanitizer (9.24 to 21.90 CFU, P less than 0.05), benzalkonium chloride-based sanitizer (6.69 to 21.59 CFU, P less than 0.05), and soap-and-water handwashing (8.43 to 22.75 CFU, P less than 0.05). There does not appear to be any difference in efficacy between single-use, long-acting sanitizer, and standard multiple-use hand hygiene methods. Hand bacterial counts increased significantly over the course of the 3-hour clinic session regardless of the hand hygiene measure used. Hand condition of subjects was improved with the ethyl alcohol

Nasal packing is commonly performed after functional endoscopic sinus surgery (FESS). However, nasal packing is associated with higher cost (owing to the cost of packing materials), patient discomfort, delayed wound healing, and concern about toxic shock syndrome. Some surgeons have been performing FESS without packing, but there are few studies that show its safety. The purpose of this study was to evaluate the safety of electrocauterization and no packing. A total of 490 patients who underwent bilateral FESS for chronic rhinosinusitis were included in this retrospective study, 242 in the nasal packing group and 248 in the electrocauterization and no-packing group. Electrocauterization was performed by using a suction coagulator. Rates of immediate (first 24 hours after surgery) and delayed postoperative bleeding were compared. Patient characteristics, including concomitant disease and medication history, and Lund-Mackay computed tomography score were also assessed Results: There were no significant differences in age; sex; Lund-Mackay score; use of anticoagulant drugs; or prevalence of hypertension, diabetes, or asthma between the two groups. In the electrocauterization and no-packing group, there were fewer patients with allergic rhinitis and more smokers. Primary bleeding did not occur in the nasal packing group, but 11 patients (4.4%) had delayed bleeding. Primary bleeding occurred in four patients (1.7%) in the electrocauterization and no-packing group, and five patients (2.1%) had delayed bleeding. There were no significant differences in primary (p = 0.058) and secondary bleeding (p = 0.142) between the two groups. All bleeding was minor and easily controlled. Multivariate logistic regression analysis ruled out significant correlation between no packing and postoperative bleeding. This study provided evidence that, in terms of postoperative hemorrhage, the safety of the electrocauterization and no-packing technique after FESS was comparable with that of

To investigate if precultivation of human engineered nasal cartilage grafts of clinically relevant size would increase the suture retention strength at implantation and the tensile and bending stiffness 2 weeks after implantation. SUMMARY BACKGROUND INFORMATION: To be used for reconstruction of nasal cartilage defects, engineered grafts need to be reliably sutured at implantation and resist to bending/tension forces about 2 weeks after surgery, when fixation is typically removed. Nasal septum chondrocytes from 4 donors were expanded for 2 passages and statically loaded on 15 x 5 x 2-mm size nonwoven meshes of esterified hyaluronan (Hyaff-11). Constructs were implanted for 2 weeks in nude mice between muscle fascia and subcutaneous tissue either directly after cell seeding or after 2 or 4 weeks of preculture in chondrogenic medium. Engineered tissues and native nasal cartilage were assessed histologically, biochemically, and biomechanically. Engineered constructs reproducibly developed with culture time into cartilaginous tissues with increasing content of glycosaminoglycans and collagen type II. Suture retention strength was significantly higher (3.6 +/- 2.2-fold) in 2-week precultured constructs than in freshly seeded meshes. Following in vivo implantation, tissues further developed and maintained the original scaffold size and shape. The bending stiffness was significantly higher (1.8 +/- 0.8-fold) if constructs were precultured for 2 weeks than if they were directly implanted, whereas tensile stiffness was close to native cartilage in all groups. In our experimental setup, preculture for 2 weeks was necessary to engineer nasal cartilage grafts with enhanced mechanical properties relevant for clinical use in facial reconstructive surgery.

The relationship between nasal surgery and its effect on continuous positive airway pressure (CPAP) device therapeutic treatment pressures and CPAP device use has not been previously systematically examined. To conduct a systematic review and meta-analysis evaluating the effect of isolated nasal surgery on therapeutic CPAP device pressures and use in adults with obstructive sleep apnea (OSA). MEDLINE, Scopus, Web of Science, and The Cochrane Library were searched through July 15, 2014. The MOOSE consensus statement and PRISMA statement were followed. Eighteen studies (279 patients) reported CPAP data after isolated nasal surgery. Seven studies (82 patients) reported preoperative and postoperative mean therapeutic CPAP device pressures and standard deviations (SD), which reduced from 11.6 ± 2.2 to 9.5 ± 2.0 centimeters of water pressure (cwp) after nasal surgery. Pooled random effects analysis demonstrated a statistically significant pressure reduction, with a mean difference (MD) of -2.66 cwp (95% confidence interval (CI), -3.65 to -1.67); P < 0.00001. Eleven studies (153 patients) reported subjective, self-reported data for CPAP use; and a subgroup analysis demonstrated that 89.1% (57 of 64 patients) who were not using CPAP prior to nasal surgery subsequently accepted, adhered to, or tolerated it after nasal surgery. Objective, device meter-based hours of use increased in 33 patients from 3.0 ± 3.1 to 5.5 ± 2.0 h in the short term (<6 mo of follow-up). Isolated nasal surgery in patients with OSA and nasal obstruction reduces therapeutic CPAP device pressures and the currently published literature's objective and subjective data consistently suggest that it also increases CPAP use in select patients. © 2015 Associated Professional Sleep Societies, LLC.

Background Pain after arthroscopic shoulder surgery is often severe, and establishing a pain treatment regimen that does not delay discharge can be challenging. The reported ability of ketamine to prevent opioid-induced hyperalgesia has not been investigated in this particular setting. Methods 300 adult patients scheduled for shoulder arthroscopy under general anesthesia were recruited for this observational clinical trial and were allotted to either receive 1mg/kg IV bolus of ketamine before surgery (ketamine group, KG) or to a control group (CG) without ketamine. NRS pain scores were obtained on the operative day and on postoperative days 1 and 2 and compared between groups. Secondary variables were blood pressure, heart rate, process times, satisfaction with the anesthetic and unwanted effects. Results Pain severity did not differ significantly between the groups at any time. Propofol injection rate and cumulative dose were higher in the KG. Heart rates and blood pressures were similar. Time to emergence and time in PACU were longer and vomiting was more frequent in patients given ketamine. Conclusion Preoperative low-dose ketamine added to a general anesthetic does not reduce perioperative pain after outpatient shoulder arthroscopy. It increases procedural times and the incidence of PONV. PMID:28352709

Dental implants have been in routine clinical use for over three decades and are a predictable treatment modality. However, as with all other aspects of dentistry, complications occur. A 50-year-old female patient with complaints of a long ongoing unpleasant altered nasal airflow presented herself at the VU University Medical Center Amsterdam. Visual inspection of the right nasal cavity revealed that the apical part of a dental implant placed in the upper right first incisor region had perforated the nasal floor and was partially protruding into the nasal cavity. Subsequent treatment consisted of a transnasal resection of the apical part of the dental implant to the level of the nasal floor. After a 12-month follow-up period, the patient reported having no altered nasal airflow. In conclusion, dental implants protruding into the nasal cavity can cause an alteration to the airflow. Furthermore, a partial removal of the apical part of the dental implant is a viable method of treating dental implants that extend into the nasal cavity.

The aim of this study is to assess the distance between the anterior nasal spine and the sphenoidal rostrum related to the LeFort I surgery in a Turkish population sample. We retrospectively reviewed multidetector computerized tomography (MDCT) scans of 209 patients (134 males and 75 females). The images were obtained on a 64-MDCT scanner. The imaging parameters were 0.5 × 64 mm slice thickness, 0.5/0.3 mm increment, 120 kV, 250 mAs, 0.5 sn rotation time, 0.641 pitch, and 512 matrix. The distance between the anterior nasal spine and the sphenoidal rostrum was assessed with the Vitrea 2 software program. The study group consisted of 134 male (mean age 57.90 ± 5.86) and 75 female (mean age 54.84 ± 4.31) patients. The distance between the anterior nasal spine and the sphenoidal rostrum was ranging between 40.4 and 70.9 mm (average 58.3 ± 5.9) in males and 45.0 and 63.2 mm in (average 55.2 ± 4.3) females. In addition, no statistically significant differences were found between genders. The results of the current study showed that after 40 mm proceeding of the ball end nasal osteotome, the surgeons must be aware of penetrating the sphenoidal rostrum.
Ambulatory surgery centers (ASCs) are freestanding facilities that provide services to patients who do not require an overnight stay. The number of ASCs has grown rapidly over the past fifteen years, as have the number of surgical procedures performed at them. ASCs now compete with hospital outpatient departments. This study examined the revenue side of ASC growth by using a large national claims database that contains information on actual prices paid. For six common outpatient surgical procedures, prices paid to ASCs on the whole grew in line with general medical care prices, while overall prices paid to hospital outpatient departments for the same procedures climbed sharply. This provides no evidence that ASCs are successfully pressuring hospital outpatient departments to lower their prices. Not unexpectedly, private insurers paid ASCs considerably more than Medicare paid ASCs for the same procedures. Medicare currently pays ASCs a legislated percentage of what it pays hospital outpatient departments for the same services, but there is a considerable discrepancy between this ratio and the ratio of payments by private insurers across provider types and procedures. This finding questions the wisdom of using a single ratio for ASC payments to hospital outpatient department payments. Project HOPE—The People-to-People Health Foundation, Inc.

Commercial gelatin-based packing materials are available under different names and compositions to be used after endoscopic sinus surgery (ESS). The purpose of this study was to investigate the efficacy of Spongostan and Cutanplast nasal packing on patients' subjective symptoms, hemostasis, and wound healing following ESS. One hundred adult patients with chronic sinusitis requiring the same extent of ESS were included. Following surgery, one nasal cavity was packed with Cutanplast and the other one with Spongostan. Patients' subjective symptoms while the packing was in situ, hemostatic properties, degree of remaining amount of packing materials, postoperative wound healing, and the cost of the pack were evaluated. Cutanplast and Spongostan are equally effective in the control of postoperative bleeding following ESS. However, Cutanplast packing was significantly more comfortable than Spongostan for nasal obstruction, postnasal drip, rhinorrhea, and headache. Furthermore, the Cutanplast packing was significantly less painful at all time points. The remaining amount of the pack was significantly lower in the Cutanplast than Spongostan packing. Spongostan packing appears to impair wound healing within the sinus cavities up to 3 months postoperatively. Cutanplast was less expensive than Spongostan as used in this study. Cutanplast may be more useful gelatin-based packing material than Spongostan in terms of efficacy and cost-benefit after ESS.

Objective: The aim of this study was to compare esmolol to nitroglycerine in terms of effectiveness in controlling hypotension during nasal surgery. Materials and Methods: After approval by our institutional Ethics Committee, 40 patients were recruited and randomized into two drug groups: esmolol (Group E) and nitroglycerine (Group N). In group E, a bolus dose of 500 μg/kg esmolol was administered over 30 sec followed by continuous administration at a dose of 25–300 μg/ kg/min to maintain systolic arterial pressure at 80 mmHg. In group N, nitroglycerine was administered at a dose of 0.5–2 μg/kg/min. Results: During the hypotensive period, systolic arterial pressure, diastolic arterial pressure, mean arterial pressure, and heart rate were decreased 24%, 33%, 27% and 35%, respectively, in group E (p<0.001, p<0.001, p<0.001, p<0.001) and were decreased 30%, 33%, 34% and 23%, respectively, in group N (p<0.001, p<0.001, p<0.001, p<0.001). The decrease in heart rate was higher in group E during the hypotensive period (p=0.048). During the recovery period, diastolic arterial pressure and heart rate were decreased 9% and 18%, respectively, in group E (p=0.044, p<0.001). Systolic arterial pressure, diastolic arterial pressure, and mean arterial pressure were decreased 7%, 3% and 7%, respectively, in group N (p=0.049, p=0.451, p=0.045). Conclusion: Esmolol provides hemodynamic stability and good surgical field visibility and should be considered as an alternative to nitroglycerine. PMID:25610218

Intraarticular (IA) local anesthetics are often used for the management and prevention of pain after arthroscopic knee surgery. Recently, IA tramadol was also used for the management of these patients. However, the IA combination of local anesthetic and tramadol has not been evaluated in arthroscopic outpatients. Our primary aim in this study was to evaluate the analgesic effect of an IA combination of bupivacaine and tramadol when compared with each drug alone using visual analog scale (VAS) pain scores in patients undergoing day-care arthroscopic knee surgery. Additionally, we assessed analgesic demand. Ninety ASA I/II patients undergoing arthroscopic partial meniscectomy, performed by a single surgeon under general anesthesia, were assigned in a randomized, double-blind manner into three groups: group B (n = 30) received 0.25% bupivacaine, group T (n = 30) received 100 mg tramadol, and group BT (n = 30) received 0.25% bupivacaine and 100 mg tramadol to a total volume of 20 mL by the IA route after surgery. Postoperative pain scores were measured on a VAS, at rest and on mobilization at 0.5, 1, 2, 4, 6, 8, 12, and 24 h. Duration of analgesia, the subsequent 24 h consumption of rescue analgesia, time to ambulation, and time to discharge were evaluated. In addition, the systemic side effects of the IA injected drugs were also assessed. The results showed significantly lower VAS pain scores in group BT (P < 0.1) when compared with groups T and B. Group BT had a later onset of postsurgical pain and longer time to first rescue analgesic than groups B and T. The 24 h consumption of analgesic was significantly less in group BT when compared with the other two groups (26.7% of the patients required rescue analgesia in group BT, whereas this number was 90% in group B and 86.7% in group T). In addition, time in hours to discharge and time to unassisted ambulation were significantly shorter in group BT when compared with groups T and B, and this was not associated with any

Objective An anaesthetic approach and surgery are important treatment strategies in patients with thyroid dysfunction due to potential complications. We investigated the prevalence of thyroid disorders, the significance of thyroid function tests (TFTs) with respect to anaesthesia in the preoperative period and the need for routine examinations. Methods A total of 10,600 patients who were admitted to the anaesthesiology outpatient clinic for surgery were retrospectively screened and enrolled between 2011 and 2013. Evident hypothyroidism was defined as free tetra-iodothyronine (fT4) <0.7 ng dL−1 and thyroid-stimulating hormone (TSH) >4 mIU mL−1, and subclinical hypothyroidism was defined as TSH >4 mIU mL−1 with normal free hormone levels. Evident hyperthyroidism was defined as fT4 >1.7 ng dL−1 and TSH <0.1 mIU mL−1, and subclinical hyperthyroidism was defined as TSH <0.1 mIU mL−1 with normal free hormone levels. Statistical analysis was conducted using the Statistical Package for the Social Sciences (SPSS) version 17.0. Independent samples t-test and one-way analysis of variance were used to compare the difference between groups. Results Of the participants, 8.5% were found to have hypothyroidism, 2.5% had hyperthyroidism, 3.5% received treatment and 2.5% had their treatment postponed. The likelihood of hypothyroidism was greater among females, and no difference was found between genders with respect to hyperthyroidism. Conclusion We believe that TFTs are important because of regional factors. However, given the high cost of TFTs and because thyroid dysfunction risk increases with age, we concluded that routine TFTs in young patients with normal physical examination findings are not mandatory.

The objective of the study was to compare the effect of sinonasal surgery vs. medical treatment on asthma in patients with chronic rhinosinusitis with or without nasal polyps. We executed a PRISMA guidelines-based systematic search of the following databases: PubMed, CENTRAL, Embase, Scopus and CINAHL. The search ran from database inception until 26 Feb 2014. We included controlled clinical trials comparing surgical intervention with medical intervention in patients with chronic rhinosinusitis with or without nasal polyps. We included only English papers. We used a pre-defined data collection form. Two authors independently assessed study quality. We assessed directness of evidence and risk of bias using pre-defined criteria. Our search yielded 2004 original articles, six of which satisfied our inclusion criteria. One article was excluded from further review because no comparison could be made of the subgroup of operated asthmatic patients versus the non-surgical control group. Only one study used objective pulmonary function measurements in asthmatics undergoing sinonasal surgery and therefore had the highest directness of evidence. Also it had a low risk of bias. Patient characteristics, treatments and outcome measures varied across studies, as did the observed effect. Risk of bias was high in most studies. Patient characteristics, treatment and outcome measurement differed across studies, making a comparison of the effects difficult. There is a risk of publication language bias. There is insufficient evidence either for or against sinonasal surgery for asthma control as compared to medical treatment.

Background: The relationship between nasal surgery and its effect on continuous positive airway pressure (CPAP) device therapeutic treatment pressures and CPAP device use has not been previously systematically examined. Study Objectives: To conduct a systematic review and meta-analysis evaluating the effect of isolated nasal surgery on therapeutic CPAP device pressures and use in adults with obstructive sleep apnea. Methods: MEDLINE, Scopus, Web of Science, and The Cochrane Library were searched through July 15, 2014. The MOOSE consensus statement and PRISMA statement were followed. Results: Eighteen studies (279 patients) reported CPAP data after isolated nasal surgery. Seven studies (82 patients) reported preoperative and postoperative mean therapeutic CPAP device pressures and standard deviations, which reduced from 11.6 ± 2.2 to 9.5 ± 2.0 centimeters of water pressure (cwp) after nasal surgery. Pooled random effects analysis demonstrated a statistically significant pressure reduction, with a mean difference of −2.66 cwp (95% confidence intervals, −3.65 to −1.67); P < 0.00001. Eleven studies (153 patients) described subjective, self-reported data for CPAP use; and a subgroup analysis demonstrated that 89.1% (57 of 64 patients) who were not using CPAP prior to nasal surgery subsequently accepted, adhered to, or tolerated it after nasal surgery. Objective, device meter-based hours of use increased in 33 patients from 3.0 ± 3.1 to 5.5 ± 2.0 h in the short term (< 6 mo of follow-up). Conclusion: Isolated nasal surgery in patients with obstructive sleep apnea and nasal obstruction reduces therapeutic CPAP device pressures and the currently published literature's objective and subjective data consistently suggest that it also increases CPAP use in select patients.

To describe the long-term outcome of a cohort of children with symptomatic adenotonsillar hypertrophy treated with aqueous nasal beclomethasone. The children enrolled completed a 4-week single-blind, saline solution controlled crossover study of aqueous beclomethasone (total: 400 micro g/d). In a 24-week open-label follow-on study, beclomethasone 200 micro g/d was offered to all patients. During a 100-week follow-up, the degree of nasal obstruction and the frequency of adenotonsillectomy were assessed. Fifty-three children of the 60 enrolled completed the study. After the 4-week crossover trial, the severity of nasal obstruction of 24 children (45%) significantly decreased during the use of nasal steroids, but no child improved when saline solution was used. At 24, 52, and 100 weeks, the 24 children who had initially improved showed a significant decrease of the severity of nasal obstruction and of the frequency of adenotonsillectomy (54% vs 83%) compared with the 29 children who had not responded after the initial steroidal therapy. Evidence from this study suggests that 45% of children with adenoidal hypertrophy improved after 2 weeks of steroidal therapy. Among these children, an additional 24-week treatment at a lower steroid dosage was associated with a significant 52- and 100-week clinical improvement and with reduction of adenotonsillectomy compared with children (55%) who had not responded after the initial 2-week steroidal therapy.

Although significant, the issue of health literacy (HL) among parents attending pediatric surgery outpatient clinics has received little attention. The objectives of this study are to determine the HL skills of parents attending the pediatric surgery outpatient clinic at McMaster Children's Hospital and to describe parent satisfaction with plain language materials. This cross-sectional study was conducted at the pediatric surgery outpatient clinic at McMaster Children's Hospital. Using convenience sampling for 4 months, parents were recruited and interviewed regarding their demographic status. The Newest Vital Sign tool was used to assess HL. Feedback on the plain language education material was received. Seventy-nine individuals were recruited, with a recruitment rate of 62%. Seventy-one percent had adequate HL. English as a first language and Canada as the place of birth were significantly correlated with adequate HL (r = 0.367, P < .001; r = 0.259, P < .05). Parents reported satisfaction with the plain language material, regardless of their HL level. Twenty-nine percent of parents showed inadequate HL, likely an underestimate owing to study limitations. Parents expressed satisfaction with the plain language material, emphasizing the need for clear, effective communication with patients and families. Future directions include evaluating staff knowledge of a universal precautions approach to health communication and the accessibility of plain language materials. Copyright © 2012 Elsevier Inc.

The aesthetic nasal proportions have played a significant role in rhinoplasty practice. On the other hand, psychological variables also play a crucial role in rhinoplasty. It is of paramount importance for facial plastic surgeons to consider both sides to achieve a more satisfactory outcome. The present study aimed to compare aesthetic nasal proportions between primary rhinoplasty candidates and a demographically matched control group to determine whether patients having rhinoplasty have different aesthetic nasal proportions compared with healthy adults who are not interested in rhinoplasty. Sixty patients having rhinoplasty were selected consecutively from a surgical clinic. A control group ( n = 60) with the same demographic characteristics was selected. Photographs were taken using a digital camera on a fixed zoom setting. All images were captured at a distance of 1.5 m. Frontal and right lateral views were used to compare nasolabial angle, nasofrontal angle, nasofacial angle, alar width, intercanthal distance, nasal length, and width-to-length ratio. Independent t tests were used for comparisons. Independent t tests verified that nasofrontal angle, nasal length, and width-to-length ratio were significantly different between the two groups ( p < 0.01). Effect sizes ranged between 0.11 and 0.69. Aesthetic proportions were not significantly different in four factors. Nasolabial angle, nasofacial angle, alar width, and intercanthal distance were not different ( p > 0.05). Four major aesthetic nasal proportions were statistically similar in a group of patients having rhinoplasty and a control group with no interest in rhinoplasty. Surprisingly, the patients having rhinoplasty showed a mean width-to-length ratio closer to aesthetic ideal. Therefore, applying for rhinoplasty may have strong psychological reasons (e.g., body dysmorphic symptoms) compared with realistic aesthetic appraisals.

These case studies describe three cases of unilateral nasal vestibular stenoses caused by chemical cauterization. Each case was treated with CO2-laser surgery together with intraoperative topic application of mitomycin or prolonged vestibular stenting for prevention of restenosis. Two patients received intraoperative mitomycin application and one patient received prolonged vestibular stenting. Results were documented using high-resolution photographs. The follow up period ranged from 1 year and 3 months to 4 years and 9 months. All patients improved after CO2-laser surgery. No complications were reported. We consider CO2-laser surgery for relief of nasal vestibular stenosis as a feasible surgical technique for relieve of nasal vestibular stenosis. Prolonged vestibular stenting seems to be an important factor for the prevention of restenosis in which the value of intraoperative mitomycin application without prolonged vestibular stenting remains uncertain.

Functional endoscopic sinus surgery (FESS) is considered to be the standard procedure for chronic rhinosinusitis with nasal polyps (CRSwNP). However, for CRSwNP that accompanies asthma, the results are not satisfying. Extensive endoscopic sinus surgery (EESS) aimed at reducing the inflammatory load has been indicated as a viable option for refractory chronic rhinosinusitis. To evaluate the clinical outcomes and safety of EESS (middle turbinate and superior turbinate resection and total ethmoidectomy) for patients with CRSwNP and with asthma. This was a prospective, single-institute cohort study conducted in a tertiary teaching hospital. Patients with CRSwNP and with asthma who were proceeding to surgery were enrolled. There were 23 patients in the EESS group and 24 patients in the FESS group. The preoperative disease severity was evaluated by the visual analog scale (VAS), Lund-Kennedy (L-K) endoscopy score, computed tomography Lund-Mackay score, asthma control test (ACT), and pulmonary function test. Clinical outcomes were comparatively evaluated between the two groups after a 1-year follow-up by using the VAS score, the postoperative endoscopic score (E score), L-K score, ACT score, and pulmonary function test. The disease severity (general VAS score, endoscopic L-K score, computed tomography score, ACT score) showed no significant differences between the two groups before surgery (p > 0.05). One year after surgery, both groups achieved significant improvement in the VAS score and endoscopic L-K score. The EESS group showed better improvement in the olfactory VAS score and E score compared with the FESS group (mean [standard deviation] change of olfactory VAS, 6.00 ± 3.67 versus 3.30 ± 3.44, p = 0.015; mean [standard deviation] E score, 0.31 ± 0.18 versus 0.66 ± 0.26, p < 0.001). No significant differences were found in the change of general nasal symptom VAS score, other individual VAS scores (nasal congestion, discharge, headache and/or facial pain), L

This study aimed to evaluate the influence of maxillary impaction orthognathic surgery on nasal respiratory function and the efficacy of bone trimming at the inferior edge of the pyriform aperture. The participants were 10 patients (3 male and 7 female patients) with mandibular prognathism who underwent bimaxillary orthognathic surgery with maxillary impaction. The surgical procedures performed were Le Fort I osteotomy with bone trimming at the inferior edge of the pyriform aperture and bilateral sagittal split osteotomy. Three-dimensional models of the nasal cavity were reconstructed from preoperative and postoperative computed tomography images. Furthermore, we remodeled the nasal valve region based on the postoperative models by adding a 1-mm and 2-mm stenosis to investigate the effects of bone trimming at the inferior edge of the pyriform aperture on the pressure effort. The 3-dimensional models were simulated with computational fluid dynamics, and the results of the pressure effort and the cross-sectional area (CSA) were compared for the anterior, middle, and posterior parts of the nasal cavity. The Wilcoxon signed rank test and Spearman rank correlation coefficients were used for statistical comparisons (P < .05). In the preoperative and postoperative models, there were considerable correlations between the CSA and the pressure effort in each part of the nasal cavity. The postoperative pressure effort showed a tendency to decrease and the CSA showed a tendency to increase in each part of the nasal cavity. In four 2-mm stenosis models, the pressure effort in the anterior nasal cavity was larger than the preoperative pressure effort and the CSA of the anterior nasal cavity was smaller than the preoperative CSA. Bone trimming at the inferior edge of the pyriform aperture appears to be useful for avoiding nasal respiratory complications with maxillary impaction.

OBJECTIVE Nasal endoscopy is an important part of the clinical evaluation of patients with chronic rhinosinusitis. However, its objectivity and inter-rater agreement have not been well studied, especially in patients who have previously had sinus surgery. METHODS Patients with a history of endoscopic sinus surgery for chronic rhinosinusitis were prospectively enrolled from a tertiary rhinology practice. Fourteen endoscopic nasal examinations were recorded using digital video capture software. Each patient also underwent computerized tomography (CT) and completed the Sinonasal Outcome Test (SNOT-22). Blinded review of inflammatory and anatomic findings for each video was independently performed by 5 academic rhinologists at separate institutions. Comparisons were performed using the unweighted Fleiss’ kappa statistic (Kf) and the prevalence- and bias-adjusted kappa (PABAK). RESULTS There were no significant correlations between age, Lund-Mackay score or SNOT-22 score. Inter-rater agreement was variable across the characteristics studied. Mean PABAK was excellent for the assessment of polyps (Kf =0.886); moderate for the assessments of middle turbinate (MT) integrity (Kf =0.543), MT position (Kf =0.443), maxillary sinus patency (Kf =0.593) and ethmoid sinus patency (Kf =0.429); fair for discharge (Kf =0.314), synechiae (Kf =0.257) and middle meatus patency (Kf =0.229); and poor for MT mucosal changes (Kf =0.148) and uncinate process (Kf =0.126). CONCLUSIONS The current study was notable for variability in the inter-rater agreement among the inflammatory and anatomic attributes that were examined. Further standardization of nasal endoscopy with regard to interpretation may improve the reliability of this procedure in clinical practice. PMID:22696506

The foremost limitation of local anesthetic solutions for spinal anesthesia in the outpatient setting is prolonged motor blockade and delayed ambulation. The purpose of this study was to determine if the addition of intrathecal fentanyl to low-dose spinal mepivacaine provides adequate anesthesia with shorter duration of functional motor blockade for ambulatory knee surgery compared with spinal mepivacaine alone. Following institutional review board approval and informed consent, 34 patients undergoing unilateral knee arthroscopy were enrolled in this study. The patients were randomly assigned to receive either 30 mg of isobaric mepivacaine 1.5% plus fentanyl 10 microg (M + F group) or 45 mg of isobaric mepivacaine 1.5% alone (M group) intrathecally. Postoperatively, the times to achieve sensory block regression to the S1 dermatome and to attain functional motor block recovery enabling ambulation were recorded. All assessments were blinded. The time to completion of Phase I recovery was shorter in the M + F group (104.6 +/- 28.4 min) than in the M group (129.1 +/- 30.4 min; P = 0.023). Regression of sensory blockade to S1 was earlier in the M + F group (118.4 +/- 53.5 min) than in the M group (169.7 +/- 38.9 min; P = 0.003). Patients in the M + F group (176.4 +/- 40.3 min) were able to ambulate significantly earlier than those in the M group (205.6 +/- 31.4 min; P = 0.025). No cases of transient or persistent neurological dysfunction were noted. When compared with 45 mg isobaric mepivacaine 1.5%, an intrathecal dose of 30 mg isobaric mepivacaine 1.5% plus 10 microg fentanyl produces reliable anesthesia, hastens block regression, shortens stay in Phase I recovery, and enables earlier ambulation for patients undergoing unilateral knee arthroscopy (Registration no. NCT00803725).

Prior research has indicated that children with developmental delay (DD) experience qualitative and quantitative differences in health care (Boulet et al., 2009). In the perioperative setting, there is concern that children with DD may be more likely to experience postoperative complications including agitation and nausea/vomiting than typically developing patients (TDP). Differences in the administration and dosage of perioperative opioids may contribute to this, however, empirical investigations are lacking. The purpose of this research was to compare the experience of postoperative nausea/vomiting and agitation, as well as to examine perioperative opioid administration, among children with DD as compared to TDP. Retrospective original research. Operating room, postanesthesia care unit. 1145 patients (1-20.9years, ASA I-III, 23.9% with a history of DD) who had undergone outpatient dental surgery involving extraction/restorations under general anesthesia. Data was obtained and analyzed from the medical records of both DD and TDP across a five-year period. Data included the experience of agitation, nausea/vomiting, as well as perioperative medication administration. Postoperative agitation and nausea/vomiting did not differ significantly between the DD and TDP groups. Children with DD were significantly less likely to receive opioids during both the intra and postoperative period (χ(2)=10.02, p=0.001 and χ(2)=8.08, p=0.003, respectively). Further, higher dosage of intraoperative opioids was predictive of reduced administration of postoperative opioids among TDP; however, no significant association was observed between the dosage of intraoperative opioids and administration of postoperative opioids in the DD group. Children with DD experience similar rates of postoperative complications including nausea/vomiting and agitation as TDP. DD children were less likely to receive both intra and postoperative opioids than TDP. Importantly, while the dosage of

Congenital anatomic deformities or acquired weakness of the lateral crura of the lower lateral cartilages after rhinoplasty could cause alar rim deformities. As lower lateral cartilages are the structural cornerstone of the ala and tip support, deformities and weakness of the alar cartilages might lead to both functional and esthetic problems. In this article, we are introducing sliding alar cartilage flap as a new technique to reshape and support nasal tip. One hundred sixty consecutive patients between 18 and 55 years of age (mean age: 27.51) were included in the study between January 2007 and May 2008. Of the total number of patients 60 were male and 100 of them were female. None of the patients had rhinoplasty procedure including lower lateral cartilage excision previously. Sliding alar cartilage technique was used in an open rhinoplasty approach to shape the nasal tip in all patients. This technique necessitates about 2 to 3 minutes for suturing and undermining the alar cartilages. The follow-up period was between 4 and 18 months. In no patients any revision related to the sliding alar cartilage technique was required. Revision was applied in 3 patients due to thick nasal tip skin and in one patient due to unpleasant columellar scar. In this article, we are presenting the "sliding alar cartilage flap" as a new technique for creating natural looking nasal tip. This technique shapes and supports nasal tip by spontaneous sliding of the cephalic portion of the lower lateral cartilage beneath the caudal alar cartilage, with minimal manipulation, without any cartilage resection, or cartilage grafting.

Previous work has established that physician attire influences patients' perceptions of their physicians. However, research from different specialties has disagreed regarding what kinds of physician attire might result in increased trust and confidence on the part of patients. The purpose of this study was to investigate how surgeon attire affects patients' perceptions of trust and confidence in an urban orthopaedic outpatient setting. Eighty-five of 100 patients solicited completed a three-part questionnaire in the outpatient orthopaedic clinic at an urban teaching hospital. In the first section, participants viewed eight images, four of a male surgeon and four of a female surgeon wearing a white coat over formal attire, scrubs, business attire, and casual attire, and rated each image on a five-level Likert scale. Participants were asked how confident, trustworthy, safe, caring, and smart the surgeon appeared, how well the surgery would go, and how willing they would be to discuss personal information with the pictured surgeon. The participant ranked all images from most to least confident in the second part and the last section obtained demographic information from the patients. Surveys were scored using a five-level Likert scale and a Friedman test was used to detect statistical significance when comparing all attires. For multiple pairwise comparisons, a Bonferroni correction was applied. The white coat on the male surgeon elicited modestly higher ratings in confidence (mean difference [MD], 0.367 ± 0.737; 95% CI, 0.202-0.532; p < 0.001), intelligence (MD, 0.216 ± 0.603; 95% CI, 0.077-0.356; p = 0.027), surgical skill (MD, 0.325 ± 0.658; 95% CI, 0.175-0.474; p < 0.001), trust (MD, 0.312 ± 0.613; 95% CI, 0.173-0.451; p < 0.001), ability to discuss confidential information (MD, 0.253 ± 0.742; 95% CI, 0.087-0.419; p = 0.023), caring (MD, 0.279 ± 0.655; 95% CI, 0.124-0.432; p = 0.006), and safety (MD, 0.260 ± 0.594; 95% CI, 0.125-0.395; p = 0.002) compared

The combination of acetaminophen, codeine, and caffeine (Tylenol 3, T3) is a standard postoperative analgesia after breast surgery despite the adverse effects and variable efficacy of narcotics. This study compared the efficacy of a nonnarcotic approach (acetaminophen and ibuprofen; AcIBU) to T3 after outpatient breast surgery. This double-blind randomized equivalence trial involved patients undergoing outpatient breast surgery. Patients were randomized (stratified by procedure type) to receive AcIBU or T3 four times daily for 7 days, or until free of pain. Pain intensity, measured four times daily by the visual analog scale, was the primary outcome; secondary outcomes were pain relief with analgesic, days until freedom from pain, adverse effects, discontinuation of drug as a result of adverse effects, and patient satisfaction. There were 71 patients randomized to AcIBU and 70 patients to T3. Repeated measures analysis showed no significant difference in average pain intensity over 7 days (AcIBU 19.9 mm vs. T3 20.6 mm; P = 0.78). Similarly, there was no significant difference in pain relief with analgesic (P = 0.46). Although no difference in the incidence of adverse effects was observed (P = 0.94), discontinuation of the study drug as a result of adverse effects was more common with T3 (19 % vs. 6 %; P = 0.018). No significant differences were identified in days until freedom from pain or patient satisfaction; 92 % of AcIBU and 89 % of T3 patients were satisfied with their pain control (P = 0.55). AcIBU is a safe, effective method of pain control after outpatient breast surgery. Compared to T3, it provides at least equivalent analgesia and has a more tolerable adverse effect profile.

The effect of functional endoscopic sinus surgery (FESS) was evaluated in 20 patients with chronic sinusitis. The physiological function of sinus mucosa and its mucociliary transport mechanism was assessed pre and post operatively in patients undergoing FESS by performing Saccharin clearance test. The effect of functional sinus surgery on nasal mucosa was evaluated using scanning electron microscopy and study of the ultrastructure of cilia in pre and post operative patients and correlation with histopathological examination. The mucociliary transport mechanism of the sinus mucosa improved 6 weeks following surgery. Histopathologically there was evidence of improvement in the ciliary population and decrease in inflammation, ulceration, fibrosis, vascular congestion, edema, squamous cell metaplasia, basement membrane thickening and polyp formation in comparison to the diseased mucosa sampled preoperatively. Scanning electron microscopic examination revealed considerable increase in the ciliary area as well as the orientation of cilia. Subjective improvement 6 weeks following surgery was confirmed by decrease in saccharin test time. This study revealed that FESS is an effective surgical procedure in chronic sinusitis and improves the overall function of the sinuses.

The main purpose of the study was to determine the impact of uvulopalatopharyngoplasty (UPPP) on nasalance and nasality. It was hypothesized that nasalance would change from the presurgical to the postsurgical condition because the surgical protocol involves removal of palatal tissue. An additional objective of the study was to provide objective and subjective data about changes in voice and articulation after UPPP. Because the surgical procedure of UPPP does not involve laryngeal tissue, it was hypothesized that the voice characteristics remain relatively stable. Because of removal of effective velar length, articulation problems of the uvular /R/ can occur in the Dutch language. Prospective study in which 26 men were studied before (1 week before UPPP) and after (3 weeks after UPPP) surgery. The Nasometer was used to obtain nasalance scores. The mirror-fogging test, a perceptual evaluation of each subject's readings, and the Gutzmann and the Bzoch hypernasality tests were used for the assessment of nasality. For the assessment of articulation, a phonetic analysis was performed. Voice assessment included a perceptual rating of the voice and a determination of fundamental frequency. No significant differences were found between the conditions before and after surgery regarding nasalance (except for the vowel /i/), nasality, and voice. Regarding articulation, only 1 patient showed a derhotacized /R/. The findings of the study indicate that UPPP does not have an impact on nasality, voice, and articulation. Regarding nasalance, no significant nasalance change occurred after UPPP, except for the high vowel /i/.

Objectives Budesonide nasal irrigation was introduced recently for postoperative management of patients with chronic rhinosinusitis. The safety and therapeutic effectiveness of this procedure is becoming accepted by many physicians. The objective of this study was to evaluate the efficacy of postoperative steroid irrigation in patients with chronic rhinosinusitis and asthma. Methods This prospective study involved 12 chronic rhinosinusitis patients with nasal polyps and asthma who received oral steroid treatment for recurring or worsening disease. The 22-item Sinonasal Outcomes Test (SNOT-22) and Lund-Kennedy endoscopy scores were checked before nasal budesonide irrigation, and 1, 2, 4, and 6 months after irrigation. We also calculated the total amount of oral steroids and inhaled steroids in the 6 months before irrigation and the 6 months after it. Results The mean SNOT-22 score improved from 30.8±14.4 before irrigation to 14.2±8.7 after 6 months of irrigation (P=0.030). The endoscopy score also improved from 7.4±4.7 before irrigation to 2.2±2.7 after 6 months (P<0.001). The total amount of oral steroid was decreased from 397.8±97.6 mg over the 6 months before irrigation to 72.7±99.7 mg over the 6 months after irrigation (P<0.001). Conclusion Nasal irrigation with budesonide is an effective postoperative treatment for chronic rhinosinusitis with asthma, which recurs frequently, reducing the oral steroid intake. PMID:27440128

To assess the efficacy of dexpanthenol nasal spray compared with normal saline spray in the postoperative treatment of patients with chronic rhinosinusitis (CRS) who underwent endoscopic sinus surgery (ESS). A prospective, randomized controlled study was conducted in CRS patients who underwent ESS. The enrolled patients had never been operated intranasally. These patients received either dexpanthenol or normal saline nasal spray intranasally four times a day for six weeks post-operatively. Fifty CRS patients were recruited in the present study. Age ranged from 23 to 63 years (means 43.4 +/- 11.2 years). Forty-four percent of patients were diagnosed as CRS without nasal polyps (NP) (CRSs NP) and 56% were CRS with NP (CRSw NP). Twenty-five cases were randomly assigned to use dexpanthenol nasal spray whereas the other 25 cases used normal saline nasal spray. The preoperative severity of CRS, determined by the computerized tomography (CT) scan scoring system of Lund-McKay was 13.9 +/- 6.2 in the dexpanthenol group and 13.6 +/- 6.9 in the normal saline group, which were not statistically different (p > 0.05). The endoscopic scoring was 10.2 +/- 2 in the dexpanthenol group and 10.7 +/- 3 in the normal saline group, which were not statistically different (p > 0.05). The mucociliary transit time improvement (time difference between pre- and post-treatment by nasal spray) was 8.4 +/- 3.3 minutes in the dexpanthenol group and 1.7 +/- 1.2 minutes in the normal saline group, which were statistically different (p < 0.05). The majority of the postoperative symptom scores and all of the endoscopic scores of the dexpanthenol group were not statistically different from those of the normal saline group. However, dexpanthenol nasal spray has superior efficacy compared with normal saline nasal spray on improvement of mucociliary clearance and nasal discharge in the postoperative care of CRS patients after ESS.

The purpose of the study was to define the therapeutic profile of outpatient gamma knife surgery (GKS) for vestibular schwannoma (VS) by using sequential tumor volumetry to quantify changes following treatment. A total of 111 patients met the inclusion criteria. The median follow-up duration was 7 years (range 5-9.6 years). Thirty-seven patients (33%) had undergone surgery before GKS and 10 (9%) had neurofibromatosis Type 2 (NF2). The median VS volume was 1.6 cm3 (range 0.08-8.7 cm3). The actuarial 6-year tumor control rate after a single GKS treatment was 95%. Tumor swelling was observed in 43 patients (38.7%). Recurrence was significantly associated with NF2 (p < 0.003) and the reduced dose (p < 0.03) delivered to these tumors. The incidence of facial nerve neuropathy was mainly determined by surgery prior to GKS (p < 0.0001). Facial nerve radiation toxicity was mild and transient. No permanent facial nerve toxicity was observed. Trigeminal neuropathy occurred in 13 patients, and this was correlated with the VS volume (p < 0.02). The median hearing loss was -10 dB (range + 20 dB to -70 dB). The risk of hearing loss was correlated with age and transient tumor swelling (p < 0.05) but not with dose parameters or NF2. Outpatient GKS is feasible, effective, and safe. Its therapeutic profile compares favorably with that of microsurgery.

This study assessed efficacy of clarithromycin "long-term" macrolide therapy as an adjunct to maintenance therapy with nasal corticosteroids to prevent recurrence of nasal polyps (NP) after functional endoscopic sinus surgery (FESS). A total of 66 patients with chronic rhinosinusitis and bilateral NP were randomized into 3 study arms, 22 patients in each arm. After FESS, patients in the first and second groups were treated with clarithromycin 250 mg/day for 12 and 24 weeks, respectively, whereas patients in the third group did not receive any clarithromycin. Patients in all 3 groups received maintenance therapy with mometasone furoate 400 μg/day. Patient assessment was conducted before the surgery and 6, 12, and 24 weeks after surgery, using a visual analogue scale (VAS), 20-item SinoNasal Outcome Test (SNOT-20), acoustic rhinometry, rhinomanometry, saccharin transit time, nasal endoscopy, computed tomography (CT) of paranasal sinuses, and measurement of the level of eosinophil cationic protein (ECP) in their nasal secretions. The study confirmed efficacy of "long-term" macrolide therapy, resulting in significant improvement of all parameters except acoustic rhinometry and VAS in both clarithromycin groups as compared to the control. Concentration of ECP in the nasal secretions increased dramatically after surgery, then returned to baseline levels after 12 and 24 weeks of treatment with clarithromycin. In the control group, ECP level continued to increase and was significantly higher at the endpoint. Both groups with clarithromycin showed significantly better endoscopic and CT scores than the control group at the end point. "Long-term" low-dose clarithromycin 250 mg/day is able to control eosinophilic inflammation and prevent early relapse of NP after FESS. © 2014 ARS-AAOA, LLC.

Chronic rhinosinusitis with nasal polyps (CRSwNP) is rare in children and has a major impact on Quality of Life (QoL). Functional endoscopic sinus surgery (FESS) has proven to be an effective treatment, but it is still unclear what long-term outcomes are in children with CRSwNP. The objective of this study was to assess long-term results of FESS in children with CRSwNP. We performed a combined prospective and retrospective study. A QoL questionnaire was send to all children with CRSwNP who received FESS between the year 2000-2010. Almost half of these children also filled in this questionnaire preoperatively. Forty-four Children underwent FESS. From 18 patients, we also prospectively collected preoperative QoL questionnaires. The mean follow-up period was 4.0 years (+- 2.9). The mean age at surgery was 13 years (+-2.9). Of these children, 9 had CF and 10 children asthma. R-SOM scores showed a significant improvement both in general symptoms as well as several different domains when comparing pre- and postoperative questionnaires. Only 5 of 44 patients needed a subsequent intervention. In children with CF this was 3 of 9. This study demonstrates that long-term results of FESS in children with CRSwNP are good. QoL has improved significantly, especially in nasal symptoms, showing that FESS is a good treatment in children with CRSwNP. Furthermore, even children with CF show good results.

Short-acting regional anesthetics have already been successfully used for peripheral nerve blocks in an ambulatory surgery setting. However, the impact on direct and indirect perioperative costs comparing 2 different short-acting local anesthetics has not been performed yet. Observational, prospective, case-control, cost-minimization study. Operating room, regional hospital One hundred adult American Society of Anesthesiologists status I-III patients scheduled for popliteal block after minor ambulatory foot surgery. Application of 30 mL chloroprocaine 3% or of 30 mL mepivacaine 1.5% for anesthesia. Cost-minimization evaluation. Direct and indirect perioperative costs were calculated. Block success, onset time and block duration, patient satisfaction, and unplanned outpatient visits or readmissions after discharge were also assessed. Onset time (sensory: 4.3 ± 2.4 vs 11.5 ± 3.2 minutes; motor: 7.1 ± 3.7 vs 18.4 ± 4.5 minutes) and block duration (sensory: 105 ± 26 vs 317 ± 46 minutes; motor: 91 ± 25 vs 216 ± 31 minutes) were significantly shorter (P < .001) when chloroprocaine 3% was used. This translated to P < .001, basically due to a faster discharge home 55 ± 1 vs 175 ± 2 minutes; P < .001) in favor of chloroprocaine 3%, without negatively affecting either block efficacy or patients satisfaction. There were no unplanned outpatient visits or readmissions and no complications in the follow-up at 6 weeks. We conclude that the more expensive chloroprocaine 3% for ambulatory foot surgery can reduce total perioperative costs and reduce length of stay in outpatient patients. Moreover, the saved time and personal resources could be used for additional cases, further increasing the revenues of an ambulatory surgical center. Copyright © 2016 Elsevier Inc.

Treatment of nasal turbinate hypertrophy with bipolar radiofrequency-induced thermotherapy (RFITT) is a common indication in patients affected by chronic vasomotor rhinitis. Nonetheless, there are no reports about the safety of such a surgical procedure in cochlear implant (CI) users, due to concerns that the spread of electrical current and heat could damage the CI inner component. We report two cases of CI recipients successfully and safely undergoing RFITT performed by means of the Olympus® Celon-ProBreath bipolar coagulation electrode. Copyright © 2011 Elsevier Ireland Ltd.

In this study, we evaluated the effects of targeted sinonasal surgery on nasal and maxillary sinus airflow patterns. A patient, who underwent right balloon sinuplasty and left uncinectomy for recurrent maxillary sinus barometric pressure, and concomitant septoplasty and bilateral inferior turbinate reduction for deviated nasal septum and inferior turbinate hypertrophy, was selected. Two 3D models representing both pre- and post-operative sinonasal morphology were constructed. The models were then used to evaluate nasal and maxillary sinus airflow patterns during respiration at ventilation rates of 7.5 L/min, 15 L/min and 30 L/min using computational fluid dynamics. The results showed that septoplasty and inferior turbinate reduction increased the nasal volume by 13.6%. The airflow patterns in the nasal cavity showed reasonably decreased resistance and slightly more even flow partitioning after the operation. Maxillary sinus ventilation significantly increased during inspiration in the left sinus after uncinectomy, and during expiration in right sinus after balloon sinuplasty. This study demonstrates computational fluid dynamics simulation is a tool in the investigation of outcomes after targeted, minimally invasive sinonasal surgery. Copyright © 2014.

We present an anatomical mapping of the most important muscles influencing the nose, incorporating constant anatomical structures, and their spatial correlations. At our disposal were the midfaces of 18 bodies of both sexes, obtained by informed consent from body donors aged between 60 and 80 years. Macroscopically, we dissected the nasal regions of eight corpses, six midfaces were prepared according to plastination histology, four by creating plastinated slices. On their way from their periosteal origin to the edge of the skin, the muscles of the nose cross the subcutaneous adipose tissue, dividing it into superficial and deep layers. The individual muscle fibers insert into the skin directly at the reticular corium. Sometimes, they reach the border of the epidermis which represents a special arrangement of corial muscle attachments. The course of the anatomical fibers of individual nasal muscles presented macroscopically and microscopically in this study offers surgeons a detailed overview of the anatomically important muscular landmarks of the midface. © 2014 Wiley Periodicals, Inc.

Narcotics are used extensively in outpatient general surgery but are often poorly tolerated with variable efficacy. Acetaminophen combined with NSAIDs is a possible alternative. The objective of this study was to compare the efficacy of acetaminophen, codeine, and caffeine (Tylenol No. 3) with acetaminophen and ibuprofen for management of pain after outpatient general surgery procedures. A double-blind randomized controlled trial was performed in patients undergoing outpatient inguinal/umbilical/ventral hernia repair or laparoscopic cholecystectomy. Patients were randomized to receive acetaminophen plus codeine plus caffeine (Tylenol No. 3) or acetaminophen plus ibuprofen (AcIBU) 4 times daily for 7 days or until pain-free. Pain intensity, measured four times daily by visual analogue scale, was the primary outcome. Secondary end points included incidence of side effects, patient satisfaction, number of days until patient was pain-free, and use of alternative analgesia. One hundred forty-six patients were randomized (74 Tylenol No. 3 and 72 AcIBU), and 139 (95%) patients completed the study. No significant differences in mean or maximum daily visual analogue scale scores were identified between the 2 groups, except on postoperative day 2, when pain was improved in AcIBU patients (p = 0.025). During the entire week, mean visual analogue scale score was modestly lower in AcIBU patients (p = 0.018). More patients in the AcIBU group, compared with Tylenol No. 3, were satisfied with their analgesia (83% versus 64%, respectively; p = 0.02). There were more side effects with Tylenol No. 3 (57% versus 41%, p = 0.045), and the discontinuation rate was also higher in Tylenol No. 3-treated patients (11% versus 3%, p = 0.044). When compared with Tylenol No. 3, AcIBU was not an inferior analgesic and was associated with fewer side effects and higher patient satisfaction. AcIBU is an effective, low-cost, and safe alternative to codeine-based narcotic analgesia for outpatient

Background Guidelines recommend that adults with congenital heart disease (CHD) undergo noncardiac surgery in regionalized centers of expertise, but no studies have assessed whether this occurs in the United States. We hypothesized that adults with CHD are less likely than children to receive care at specialized CHD centers. Methods Using a comprehensive state ambulatory surgical registry (California Ambulatory Surgery Database, 2005–2011), we calculated the proportion of adult and pediatric patients with CHD who had surgery at a CHD center, distance to the nearest CHD center, and distance to the facility where surgery was performed. Results Patients with CHD accounted for a larger proportion of the pediatric population (n = 11,254, 1.0%) than the adult population (n = 10,547, 0.07%). Only 2,741 (26.0%) adults with CHD had surgery in a CHD center compared to 6,403 (56.9%) children (p<0.0001). Adult CHD patients who had surgery at a non-specialty center (11.9±15.4 miles away) lived farther from the nearest CHD center (37.9±43.0 miles) than adult CHD patients who had surgery at a CHD center (23.2±28.4 miles; p<0.0001). Pediatric CHD patients who had surgery at a non-specialty center (18.0±20.7 miles away) lived farther from the nearest CHD center (35.7±45.2 miles) than pediatric CHD patients who had surgery at a CHD center (22.4±26.0 miles; p<0.0001). Conclusions Unlike children with CHD, most adults with CHD (74%) do not have outpatient surgery at a CHD center. For both adults and children with CHD, greater distance from a CHD center is associated with having surgery at a non-specialty center. These results have significant public health implications in that they suggest a failing to achieve adequate regional access to specialized ACHD care. Further studies will be required to evaluate potential strategies to more reliably direct this vulnerable population to centers of expertise. PMID:25247694

Background Due to cost-containment efforts, preparation programs for outpatient surgery are currently not available to the majority of children and parents. The recent dramatic growth in the Internet presents a unique opportunity to transform how children and their parents are prepared for surgery. In this article we describe the development of a Web-based tailored preparation program for children and parents undergoing surgery (WebTIPS). Development of Program A multidisciplinary taskforce agreed that a Web-based tailored intervention comprised of intake, matrix and output modules was the preferred approach. Next, the content of the various intake variables, the matrix logic and the output content was developed. The output product has a parent component and a child component and is described in http://surgerywebtips.com/about.php. The child component makes use of preparation strategies such as information provision, modeling, play and coping skills training. The parent component of WebTIPS includes strategies such as information provision, coping skills training, relaxation and distraction techniques. A reputable animation and Web-design company developed a secured Web-based product based on the above description. Conclusions In this article we describe the development of a Web-based tailored preoperative preparation program that can be accessed by children and parents multiple times before and after surgery. A follow-up article in this issue of Anesthesia & Analgesia describes formative evaluation and preliminary efficacy testing of this Web-based tailored preoperative preparation program. PMID:25790212

Postoperative mucosal regeneration of the middle ear cavity and the mastoid cavity is of great importance after middle ear surgery. However, the epithelialization of the mucosa in the middle ear is retarded because chronic inflammation without epithelialization aggravates gas exchange and clinical function. These environmental conditions in the middle ear lead to postoperative retraction and adhesion of the newly-formed tympanic membrane. Therefore, if the mucosa on the exposed middle ear bone surface can be rapidly regenerated after surgery, the surgical treatments for cholesteatoma and adhesive middle ear disease can potentially be improved. In this study, we successfully generated a cell sheet designed for the postoperative treatment of cholesteatoma. We used nasal cells to create an artificial middle ear mucosal cell sheet with a three-dimensional (3D) configuration similar to that of the middle ear mucosa. The sheets consisted of multi-layered mucosal epithelia and lower connective tissue and were similar to normal middle ear mucosa. This result indicates that tissue-engineered mucosal cell sheets would be useful to minimize complications after surgical operations in the middle ear and future clinical applications are expected.

To establish the safety of staged interpolation flaps performed in an outpatient dermatologic clinic setting. A retrospective chart review was performed of patients who underwent staged interpolation flap reconstruction by a single dermatologic surgeon after tumor clearance using Mohs micrographic surgery from 2000 to 2012 at the Department of Dermatology, Medical University of South Carolina. Six hundred fifty-three staged flaps were performed in 639 patients (mean age 65) between June 2000 and November 2012. Types of flaps included paramedian forehead flaps (n = 291, 45%), two-stage melolabial flaps (n = 256, 39%), retroauricular flaps (n = 58, 9%), interpolated paranasal flaps (n = 40, 6%), and Abbe or Abbe-Estlander flaps (n = 8, 1%). No major complications were observed. Of the minor complications, problems related to bleeding were the most prevalent; active bleeding requiring physician intervention was seen in 8.4% and hematoma formation in 0.4% of flaps. Postoperative infections were seen in 1.7% of patients after the initial surgery and 3.4% after division of the pedicle. Primary or secondary dehiscence was seen in 0.5%. Partial full-thickness flap necrosis was seen in 2.3% and total flap necrosis in 0.6%. The rate of complications associated with dermatologic surgeons performing interpolated flaps in an outpatient setting under local anesthesia is low. Our complication rates are equal to or lower than published complication rates from other surgical specialties. © 2013 by the American Society for Dermatologic Surgery, Inc.

Nasal obstruction is a frequent complaint in otorhinolaryngology outpatient clinics, and nasal valve incompetence is the cause in most cases. Scientific publications describing surgical techniques on the upper and lower lateral cartilages to improve the nasal valve are also quite frequent. Relatively few authors currently describe surgical procedures in the piriform aperture for nasal valve augmentation. We describe the surgical technique called pyriform plasty and evaluate its effectiveness subjectively through the NOSE questionnaire and objectively through the rhinomanometry evaluation. To compare pre- and post-pyriform plasty nasal airflow variations using rhinomanometry and the NOSE questionnaire. Eight patients submitted to pyriform surgery were studied. These patients were screened in the otorhinolaryngology outpatient clinic among those who complained of nasal obstruction, and who had a positive response to Cottle maneuver. They answered the NOSE questionnaire and were submitted to preoperative rhinomanometry. After 90 days, they were reassessed through the NOSE questionnaire and the postoperative rhinomanometry. The results of these two parameters were compared pre- and postoperatively. Regarding the subjective measure, the NOSE questionnaire, seven patients reported improvement, of which two reported marked improvement, and one patient reported an unchanged obstructive condition. Regarding the rhinomanometry assessment, of 96 comparative measurements between the preoperative and postoperative periods, we obtained 68 measurements with an increase in nasal airflow in the postoperative period, 26 negative results, and two cases that remained unaltered between the preoperative and postoperative periods. When analyzing the results obtained in this study, we can conclude that the piriform plasty surgical procedure resulted in nasal airflow improvement in most of the obtained measurements.

Background: We sought to compare the effectiveness of oxygen (O2) treatment administered by an O2 mask and nasal continuous positive airway pressure (NCPAP) in infants after congenital cardiac surgery. Methods: In this retrospective observational study, 54 infants undergoing corrective cardiac surgery were enrolled. According to the anesthesiologist's preference, the patients ventilated for more than 48 h were either put on NCPAP or O2 mask immediately after extubation. From pre-extubation to 24 h after treatment, arterial blood gas and hemodynamic data were measured. Results: After 24 h of NCPAP institution, the patients showed a significant improvement in oxygenation compared to O2 mask group. Respiratory rate (per minute) decreased from 31.67 ± 4.55 to 24.31 ± 3.69 (P < 0.0001), PO2 (mmHg) increased from 112.12 ± 22.83 to 185.74 ± 14.81 (P < 0.0001), and PCO2 (mmHg) decreased from 42.88 ± 5.01 to 37.00 ± 7.22 (P < 0.0076) in patients on NCPAP. In this group, mean pediatric cardiac surgical Intensive Care Unit (PCSICU) stay was 4.72 ± 1.60 days, with only 2 (11.11%) patients requiring re-intubation. Conclusion: NCPAP can be used safely and effectively in infants undergoing congenital cardiac surgery to improve oxygenation/ventilation. It also reduces the work of breathing, PCSICU stay, and may reduce the likelihood of re-intubation. PMID:28163425

The aim of the present prospective, randomized, double-blind, and placebo-controlled investigation (approved by the Ethical Committee of Padova University Hospital [Italy]) was to assess the effect of a nasal gel containing a combination of silver sucrose octasulfate and potassium sucrose octasulfate (Silsos gel® [SG]) in wound healing after endoscopic sinus surgery (ESS) for chronic rhinosinusitis in terms of: nasal symptoms (SNOT22), endoscopic appearance of the sinonasal mucosa (Lund-Kennedy score), nasal air flow (anterior active rhinomanometry), evidence of mucosal inflammatory processes (nasal cytology and histology), and microbiological growth. Thirty-four patients with chronic rhinosinusitis were randomized on a 1:1 ratio to receive after ESS either SG or placebo (contained only the excipients [carbopol and propylene glycol] in the same concentrations as in SG). Judging from the present prospective investigation on patients who underwent ESS for chronic rhinosinusitis, treatment with SG seems to enable a significantly faster improvement in specific symptoms (assessed on the validated SNOT22 scale) than placebo. Patients treated with SG also had a quicker improvement in the endoscopic appearance of their nasal mucosa after ESS than patients treated with placebo. These endoscopic improvements in the SG group were also confirmed at the long-term follow-up, while the same did not apply to the placebo-treated group. Copyright © 2015 Elsevier Inc.

OBJECTIVE In an era of escalating health care costs and pressure to improve efficiency and cost of care, ambulatory surgery centers (ASCs) have emerged as lower-cost options for many surgical therapies. Anterior cervical discectomy and fusion (ACDF) is one of the most prevalent spine surgeries performed, and the frequency of its performance is rapidly increasing as the aging population grows. Although ASCs offer significant cost advantages over hospital-based surgical centers, concern over the safety of outpatient ACDF has slowed its adoption. The authors intended to 1) determine the safety of the first 1000 consecutive ACDF surgeries performed in their outpatient ASC, and 2) compare the safety of these outpatient ACDFs with that of consecutive ACDFs performed during the same time period in the hospital setting. METHODS A total of 1000 consecutive patients who underwent ACDF in an ACS (outpatient ACDF) and 484 consecutive patients who underwent ACDF at Vanderbilt University Hospital (inpatient ACDF) from 2006 to 2013 were included in this retrospective study of patients' medical records. Data were collected on patient demographics, comorbidities, operative details, and perioperative and 90-day morbidity. Perioperative morbidity and hospital readmission were compared between the outpatient and inpatient ACDF groups. RESULTS Of the first 1000 outpatient ACDF cases performed in the authors' ASC, 629 (62.9%) were 1-level and 365 (36.5%) were 2-level ACDFs. Mean patient age was 49.5 ± 8.6, and 484 (48.4%) were males. All patients were observed postoperatively at the ASC postanesthesia care unit (PACU) for 4 hours before being discharged home. Eight patients (0.8%) were transferred from the surgery center to the hospital postoperatively (for pain control [n = 3], chest pain and electrocardiogram changes [n = 2], intraoperative CSF leak [n = 1], postoperative hematoma [n = 1], and profound postoperative weakness and surgical reexploration [n = 1]).

Calcium alginate is a biodegradable gel-transforming agent widely used for nasal packing. It can reduce pain and improve comfort. However, few randomised controlled trials have compared the efficacy of calcium alginate nasal packing with that of other biodegradable gel-transforming materials. Prospective, randomised, single-blinded controlled study. Yonsei University Severance Hospital, a tertiary academic medical centre. Twenty-seven patients (54 nostrils) with chronic rhinosinusitis who were scheduled for bilateral endoscopic sinus surgery were enrolled. After surgery, one nostril was packed with calcium alginate and the other with carboxymethyl cellulose. Only patients with an intersinus chronic rhinosinusitis severity score difference of ≤1 were included. Visual analogue scale (VAS) scores for postoperative pain, discomfort from nasal discharge and pain during packing removal were analysed. Two independent rhinologists who were blinded to the assessments separately scored adhesions, oedema and infection by endoscopic digital photography at 1, 4 and 8 weeks postoperatively. There were no significant differences in VAS scores for postoperative pain, discomfort from nasal discharge or pain during packing removal between calcium alginate packings and carboxymethyl cellulose packings. Inter-rater variability of adhesion, oedema and infection scores was acceptable. Adhesion severity and oedema scores at 4 weeks were significantly lower with calcium alginate packing than with carboxymethyl cellulose. Infection severity scores also tended to be lower with calcium alginate than with carboxymethyl cellulose, but the difference was not significant. Calcium alginate nasal packing is associated with reduced severity of oedema and adhesions after endoscopic sinus surgery. © 2015 John Wiley & Sons Ltd.

The problem of professional liability in case of adverse outcomes or failures secondary to surgery is very sensitive in many countries of the European Community. In Italy, a recent sentence of the Supreme Court concerning a patient who underwent septoplasty raised considerable doubts in relation to the guidance to be followed in disputes related to an alleged professional liability, further exacerbating the juridical orientation of recent years in this context. This ruling involves any surgery, as well as rhinologic surgery, and calls into question most regulatory and legal principles that have traditionally been adopted by the Italian Civil Law. The sentence states that the plaintiff is only required to document the failure of surgical treatment, but not the breach of the duty of care by the surgeon, thus shifting the burden of proof to the physician-debtor. It also considers that, in assessing the degree of negligence, reference should be made to the qualifications of the surgeon, according to principles that are not covered by current regulations, denying that in general surgery (i.e., not with aesthetic purposes) the surgeon must only to act with diligence and need not guarantee a favourable outcome. This series of statements, complementing one another and evolving more unfavourably towards physicians, facilitate legal disputes for speculative purposes through complainants, with obvious health and socio-economic implications.

Chronic rhinosinusitis with nasal polyps is a chronic disease frequently seen in otorhinolaryngological practice. Along with its chronic disease burden it creates high societal costs. Therapy consists of long-term use of medication and, if insufficient, endoscopic sinus surgery. No consensus exists on the right timing and extent of disease that warrants surgery. Furthermore, there is lack of clinical knowledge about the benefit of surgery over medication only. The current trial evaluates the clinical effectiveness and cost-effectiveness of endoscopic sinus surgery in addition to drug treatment versus medication exclusively in the adult patient group with nasal polyps. A prospective, multicentre, superiority, randomised controlled (PolypESS) trial in 238 patients aged 18 years or older selected for primary or revision endoscopic sinus surgery by the otorhinolaryngologist was designed. Patients will be randomised to either endoscopic sinus surgery in addition to medication or medical therapy only. Relevant data will be collected prior to randomisation, at baseline and 3, 6, 12, 18 and 24 months after start of treatment. Complete follow-up will be 24 months. Primary outcome is disease-specific Health-related Quality of Life quantified by the SNOT-22 after 12-month follow-up. Secondary outcomes are generic Health-related Quality of Life, cost-effectiveness, objective signs of disease and adverse effects of treatment. Subgroup analyses will be performed to verify whether treatment effects differ among patient phenotypes. The PolypESS trial will investigate tailored care in adult patients with chronic rhinosinusitis with nasal polyps and will result in improved clinical pathways to help to determine in which circumstances to perform surgery.

Opioids are frequently used for treatment of moderate to severe short-term pain, but concerns exist about this treatment approach. Ketorolac tromethamine nasal spray, a nonsteroidal anti-inflammatory, is indicated for the short-term management of moderate to moderately severe pain requiring analgesia at the opioid level. However, there are no direct comparison studies between ketorolac nasal spray and opioids. The objective of this study was to use an effect size analysis to compare the effectiveness of ketorolac nasal spray with oral combination opioid formulations in treating moderate to severe short-term pain. An effect size analysis of three randomized, double-blind, placebo-controlled studies of third molar extraction surgery compared pain relief with ketorolac nasal spray and commonly prescribed combination opioids including hydrocodone/acetaminophen (APAP), oxycodone/APAP, oxycodone/ibuprofen and tramadol HCl/APAP. Effect size comparisons were made using total pain relief scores (TOTPAR6 or TOTPAR8; the weighted sum of pain relief scores through 6 or 8 h). Pain relief was measured using a five-point categorical rating scale (0 = none; 4 = complete). The effect size equivalent correlation, r, was determined using an online effect size calculator. The treatment effect size r compared with placebo was classified using established criteria (small = 0.20-0.49, moderate = 0.50-0.79 and large = ≥ 0.80). TOTPAR6 data indicated a moderate effect size for ketorolac nasal spray 31.5 mg (0.51) and oxycodone/ibuprofen 5/400 mg (0.64) and a small effect size for hydrocodone/APAP 7.5/500 mg (0.24) and oxycodone/APAP 5/325 mg (0.32). TOTPAR8 data indicated small effect sizes for ketorolac nasal spray (0.48), hydrocodone/APAP 10/650 mg (0.43), tramadol HCl/APAP 75/650 mg (0.35) and tramadol HCl/APAP 37.5/325 mg (0.17). The treatment effect sizes of ketorolac nasal spray were similar to or higher than the opioid comparators after third molar surgery, a well-accepted pain

In a randomized double-blind, parallel groups study, 39 patients undergoing surgical removal of impacted third molar teeth received either temazepam 40 mg by mouth (as soft gelatin capsules) followed at 35 min by i.v. saline, or oral placebo followed at 35 min by i.v. diazepam 10 mg (Diazemuls). Rapid onset of significant anxiolytic activity and psychomotor depression was seen following temazepam, while the pattern and duration of postoperative sedation measured with standard psychometric tests, were similar for both treatments. Ratings by the surgeon and by the patients indicated that sedation following the two treatments was comparable. No significant cardiovascular complications were found with either treatment. The findings indicate that rapidly acting oral benzodiazepines such as temazepam provide safe, effective alternatives to i.v. diazepam for sedation in outpatients undergoing minor surgical procedures.

Research Objective To compare quality outcomes from surgical procedures performed at freestanding ambulatory surgery centers (ASCs) and hospital-based outpatient departments (HOPDs). Data Sources Patient-level ambulatory surgery (1997–2004), hospital discharge (1997–2004), and vital statistics data (1997–2004) for the state of Florida were assembled and analyzed. Study Design We used a pooled, cross-sectional design. Logistic regressions with time fixed-effects were estimated separately for the 12 most common ambulatory surgical procedures. Our quality outcomes were risk-adjusted 7-day and 30-day mortality and 7-day and 30-day unexpected hospitalizations. Risk-adjustment for patient demographic characteristics and severity of illness were calculated using the DCG/HCC methodology adjusting for primary diagnosis only and separately for all available diagnoses. Principal Findings Although neither ASCs nor HOPDs performed better overall, we found some difference by procedure that varied based on the risk-adjustment approach used. Conclusions There appear to be important variations in quality outcomes for certain procedures, which may be related to differences in organizational structure, processes, and strategies between ASCs and HOPDs. The study also confirms the importance of risk-adjustment for comorbidities when using administrative data, particularly for procedures that are sensitive to differences in severity. PMID:22568615

This study investigated whether the addition of 25 microg fentanyl to an ultra-low (sub-anaesthetic) dose of intrathecal bupivacaine provides adequate anaesthesia for out-patient anorectal surgery, without increasing side-effects or delaying hospital discharge. Patients were randomly allocated to receive 2.5 mg 0.5% bupivacaine plus 25 microg fentanyl (group BF, n = 18) or 5 mg 0.5% bupivacaine alone (group B, n = 17). There were no significant differences in intra-operative outcomes, but mean recovery and discharge times were significantly shorter in group BF. There were no between-group differences in hypotension, bradycardia or respiratory depression and post-operative complications were comparable, apart from pruritus which was significantly more frequent in group BF. Fewer patients requested analgesic medication in the early post-operative period in group BF than in group B. In conclusion, 25 microg intrathecal fentanyl added to ultra-low dose (2.5 mg) bupivacaine provided good-quality spinal anaesthesia and reduced post-operative analgesic requirement in patients undergoing ambulatory anorectal surgery.

Multiple chemical sensitivity syndrome is a group of complex disorders that include psychiatric disorders, chronic fatigue and/or respiratory problems. This syndrome could be triggered by specific allergens and toxins that cause neurophysiological sensitization and the appearance of the clinical symptomatology. Anaesthesia for these patients always poses a challenge for the anaesthetist, because they need to find and use drugs that do not trigger or aggravate the symptoms of the disease. Therefore, sevoflurane in these circumstances might be "the ideal anaesthetic". Performing general anaesthesia with sevoflurane as the sole anaesthetic agent, together with a series of environmental measures formed the basis for successful anaesthesia and surgery in our patient with a multiple chemical sensitivity syndrome.

The purpose of this study was to assess the safety and efficacy of intranasal procedures carried out simultaneously with bimaxillary orthognathic surgery. The authors executed a retrospective cohort study derived from patients treated by a single surgeon at 1 institution from 2004 through 2013 with a minimum follow-up of 1 year (range, 1 to 10 yr). An index study group consisting of a consecutive series of patients with symptomatic chronic obstructive nasal breathing (CONB) and a bimaxillary developmental dentofacial deformity (DFD) also involving the chin were identified. They underwent a minimum of: Le Fort I osteotomy, bilateral sagittal ramus osteotomies, septoplasty, inferior turbinate reduction (ITR), and osseous genioplasty. Study variables included age at operation, gender, pattern of presenting DFD, presence of obstructive sleep apnea, segmentation of the maxilla, and airway management. The primary outcome variable studied was residual CONB. During the study period, 262 patients met the inclusion criteria. Their age at operation averaged 25 years (range, 13 to 63 yr) and 134 were female (51%). The major patterns of presenting DFD included long face (29%) and maxillary deficiency (25%). No patients required nasal packing, reintubation, tracheostomy, or blood transfusion. In 6 of the 262 patients (2%), the intranasal procedures did not resolve nasal breathing difficulties. In these patients, procedures recommended included synechiae release (n = 3), revision septoplasty (n = 3), and further ITR (n = 4). An association between age at time of surgery and non-segmental Le Fort I osteotomy with the occurrence of residual nasal obstruction was confirmed. When completing septoplasty and ITR through a Le Fort I, airway management need not be altered from standard protocol. The management of CONB in conjunction with orthognathic surgery is highly effective, with few complications. Non-segmental Le Fort I in patients at least 40 years of age is more likely to be

Nasal packs are indispensable in ENT practice. This study reviews current indications, effectiveness and risks of nasal packs and stents. In endoscopic surgery, nasal packs should always have smooth surfaces to minimize mucosal damage, improve wound healing and increase patient comfort. Functional endoscopic endonasal sinus surgery allows the use of modern nasal packs, since pressure is no longer required. So called hemostatic/resorbable materials are a first step in this direction. However, they may lead to adhesions and foreign body reactions in mucosal membranes. Simple occlusion is an effective method for creating a moist milieu for improved wound healing and avoiding dryness. Stenting of the frontal sinus is recommended if surgery fails to produce a wide, physiologically shaped drainage path that is sufficiently covered by intact tissue. PMID:22073095

Individuals who abuse prescription opioids often use leftover pills that were prescribed for friends or family members. Dental surgery has been identified as a common source of opioid prescriptions. We measured rates of used and unused opioids after dental surgery for a pilot program to promote safe drug disposal. We conducted a randomized controlled trial of opioid use patterns among patients undergoing surgical tooth extraction at a university-affiliated oral surgery practice. The primary objective was to describe opioid prescribing and consumption patterns, with the number of unused opioid pills remaining on postoperative day 21 serving as the primary outcome. The secondary aim was to measure the effect of a behavioral intervention (informing patients of a pharmacy-based opioid disposal program) on the proportion of patients who disposed or reported intent to dispose of unused opioids. (NCT02814305) Results: We enrolled 79 patients, of whom 72 filled opioid prescriptions. On average, patients received 28 opioid pills and had 15 pills (54%) left over, for a total of 1010 unused pills among the cohort. The behavioral intervention was associated with a 22% absolute increase in the proportion of patients who disposed or reported intent to dispose of unused opioids (Fisher's exact p=0.11). Fifty-four percent of opioids prescribed in this pilot study were not used. The pharmacy-based drug disposal intervention showed a robust effect size but did not achieve statistical significance. Dentists and oral surgeons could potentially reduce opioid diversion by moderately reducing the quantity of opioid analgesics prescribed after surgery. Copyright © 2016.

The use of elastomeric devices for ambulatory intravenous pain treatment in Major Ambulatory Surgery (MAS) has been described to improve postoperative pain management. The objective of the study was to describe the first 3 years experience of the use of elastomeric devices for ambulatory intravenous pain treatment in MAS implemented at our site since 2010. Data were retrieved from the medical records for all patients who, between January 2010 and March 2014, underwent surgical procedures at the ambulatory surgical centre at our hospital and were prescribed a home-based continuous intravenous analgesia. Data were retrieved from the medical records of 1128 patients. The most frequent surgical interventions included orthopedic and proctology surgeries. 80 % of patients were discharged home without pain; during the first 48 h after discharge roughly 40 % of subjects were completely free of pain, 50 % reported mild pain (VAS 1 to 3) and 9 % reported higher pain scores (4 and above). Peripheral nerve block was associated to better pain control in the immediate postoperative period. Vomiting in the first 24 h was 4.6 % before introducing haloperidol into the drug schemes, and 2.6 % thereafter. Complications related with the intravenous route required treatment withdrawal in 1.1 % cases. Only 3.5 % of patients returned to the hospital in the first 72 h, mainly for non-pain related reasons. Overall, 99.5 % of patients were satisfied with the treatment received at home. Our initial experience suggest that outpatient multimodal intravenous analgesia in patients undergoing day-case surgery is a feasible alternative in our setting, that allows an effective management of postoperative pain with a small rate of adverse events and complications requiring readmission.

For plastic surgeons, independent development of outpatient surgical centers and specialty facilities is becoming increasingly common. These facilities serve as important avenues not only for increasing access and efficiency but in maintaining a sustainable, competitive specialty advantage. Certificate of Need regulation represents a major hurdle to plastic surgeons who attempt to create autonomy in this fashion. At the state level, Certificate of Need programs were initially established in an effort to reduce health care costs by preventing unnecessary capital outlays for facility expansion (i.e., managing supply of health care resources) in addition to assisting with patient safety and access to care. The purpose of this study was to examine the effect of Certificate of Need regulations on health care costs, patient safety, and access to care and to discuss specific implications of these regulations for plastic surgeons. Within Certificate of Need states, these regulations have done little, if anything, to control health care costs or affect patient safety. Presently, Certificate of Need effects coupled with recent provisions in the Medicare Modernization Act banning development of specialty hospitals may restrict patient access to ambulatory surgical and specialty care. For the plastic surgeon, these effects not only act as an economic barrier to entry but can threaten the efficiencies gained from providing surgical care in an ambulatory setting. An appreciation of these effects is critical to maintaining specialty autonomy and access to fiscal policy.

To explore use of 'Invitations to Ask Questions' (IAQs) by plastic surgeons in outpatient consultations, and consider how type of IAQ impacts on patients' responses to, and recollection of, IAQs. Descriptive study: 63 patients were audio recorded in consultation with 5 plastic surgeons, and completed a brief questionnaire immediately after the consultation. Consultation transcripts were analyzed using inductive qualitative methods of Discourse Analysis and compared with questionnaire findings. A taxonomy of IAQs was developed, including three types of IAQ (Overt, Covert, and Borderline). Overt IAQs were rarely identified, and almost all IAQs occurred in the closing stages of the consultation. However, when an overt IAQ was used, patients always recollected being asked if they had any questions after the consultation. Patients are rarely explicitly offered the opportunity to ask questions. When this does occur, it is often in the closing stages of the consultation. Clinicians should openly encourage patients to ask questions frequently throughout the consultation, and be mindful that subtle differences in construction of these utterances may impact upon interpretation. Clear communication, of message and intention, is essential in clinical encounters to minimize misunderstanding, misinterpretation, or missed opportunities for patients to raise concerns.

Nasal polyps are associated with the inflammation of the nasal cavity and the sinus mucosa. When medical treatment cannot solve a patient's problem, a functional endoscopic sinus surgery may be indicated. Bleeding impairs the surgery field during operation and increases the operation risk and time. Pre-operative corticosteroids can reduce bleeding during surgery. In this study, we have evaluated the effect of pre-operative single-dose prednisolone (1 mg/Kg/dose 24 h before surgery) versus 5-day prednisolone (1 mg/Kg/day before operation) on the bleeding volume and the surgery field quality during FESS. In this mono blind randomized clinical trial, 80 patients with bilateral nasal polyps were randomly assigned in two groups. The first group (A) received a single dose of 1 mg/Kg/dose prednisolone on the day before the surgery. The second group (B) received 1 mg/Kg/day prednisolone for 5 days before the operation. The patients were operated on under general anesthesia through the same protocol. The mean arterial blood pressure was 70-80 mm Hg in both groups. The surgeons were not aware of the patients' group. The bleeding volume and the surgeons' opinion about the surgery field quality were recorded at the end of the procedure and analyzed by Chi-square and t test. The two groups were not significantly different in their overall demographic and clinical characteristics. The mean bleeding volume during the operation was 266.5 ± 96.31 ml in group A and 206 ± 52.81 ml in group B; there was a significant difference between the groups (P value = 0.038). There was no significant difference between the groups in the surgeons' opinion about the surgery field quality (P value = 0.09). In conclusion, unlike a single dose (1 mg/kg/dose), treatment with 5-day prednisolone (1 mg/kg/day) can reduce blood loss during FESS more efficiently and may improve the surgery field quality slightly. But this difference is not clinically significant.
Rhinoplasty is a surgical procedure that aims to improve nasal aesthetics and nasal breathing. The aesthetic improvement of the nose is usually judged subjectively by the patient and the surgeon, but the degree of improvement of nasal obstruction is difficult to assess by clinical examination only. The measurement of peak nasal inspiratory flow (PNIF) is a reliable tool that has been shown to correlate with other objective methods of assessing nasal breathing and with patients' symptoms of nasal obstruction. Twenty-three consecutive patients undergoing rhinoplasty have been evaluated by measurement of PNIF before and after surgery. All but three patients had an increase in PNIF after surgery. The mean preoperative PNIF was 86.5 L/min and the mean postoperative PNIF was 123.0 L/min ( P < 0.001). Not surprisingly, the greatest improvement in PNIF was achieved when bilateral spreader grafts were used. This study suggests that rhinoplasty does improve nasal breathing.

ASPAN guidelines for the prevention of unplanned perioperative hypothermia define normothermia as a core temperature between 36 and 38 degrees C and an acceptable level of warmth. Over a six-month period, more than 30% of the same-day surgery patients experienced hypothermic core temperatures on admission to the preoperative unit. The purpose of the study was to compare two preoperative warming methods (forced-air gowns vs traditional warmed cotton blankets) on oral body temperatures, and patients reported "thermal" comfort in ambulatory surgery patients. A repeated measures experimental design study included 150 subjects in Pre-op who were randomly assigned to either the control warmed blankets group or the experimental forced-air gown group. Oral temperatures and thermal comfort assessments were measured every 30 minutes while the patients were in Pre-op, and on admission and discharge from the Phase I PACU. There was no significant difference in postoperative temperature between the subjects warmed with blankets and the warm-air gowns. Subjects warmed with the warm-air gowns reported higher comfort scores after 30 minutes of warming than those warmed with blankets. The change in comfort score from baseline to 30 minutes post warming was greater in the warm-air gown group (P = .001), indicating that warm-air gowns contribute to patients' increased thermal comfort.

The aim of this study was to evaluate the levels of fear and anxiety in patients undergoing different types of minor oral surgery procedures by using conventional rating scales adjusted to the population characteristics. A demographic form and translated versions of the Modified Dental Anxiety Scale (MDAS) and Dental Fear Survey (DFS) were completed by 500 patients having hard or soft tissue pathologies, third molar removal, implant placement, tooth extraction procedures and 200 non-clinical participants. MDAS and DFS were highly correlated (r = 0.79; P < 0.05). The structural properties of the MDAS were similar to the original, but the DFS required substantive changes to achieve comparable measurement properties. Anxiety levels decreased with age and were greater in females, those with higher education and following a previous unpleasant experience (P < 0.05 for all). The third molar group scored higher than most of the surgical categories in both questionnaires (P < 0.05 for each). DFS showed they tended to avoid surgical procedures and were more susceptible to environmental and chair-side effects (P<0.05 for all). Regarding oral surgery, third molar patients should be targeted to increase overall comfort of the treatment. Assessments should be adjusted to cultural differences.

Surgery is a highly stressful event for children and caregivers. Extensive effort has been made to improve preoperative care in order to alleviate worry about the surgical procedure itself. This study tested the impact of an educational multimedia intervention on the cognitive, emotional, and physiological responses of children undergoing surgery, as well as on parental state anxiety. Children (n = 90) were assigned to three different groups: an educational multimedia intervention (experimental group), an entertainment video game intervention (comparison group), and a control group (no intervention). Children who received the educational multimedia intervention reported lower level of worries about hospitalization, medical procedures, illness, and negative consequences than those in the control and in the comparison groups. Parental state anxiety was also lower in the both the educational and the entertainment video game interventions compared to the control group. These findings suggest that providing information to children regarding medical procedures and hospital rules and routines is important to reduce their preoperative worries, and also relevant for parental anxiety.

Background Nasal packs are utilized nearly by otorhinolaryngologists for controlling epistaxis and post nasal procedures. Complications have been reported due to them; therefore the use of antibiotics is a common practice among otorhinolaryngologists. Objective To detect microbiological flora associated with nasal packing and find evidence to support the benefit of systemic antibiotics with it. Method A prospective, analytical study was conducted on 51 patients presenting to the Department of ENT, KUSMS from June to September 2015 who required nasal packing. Approval of the local Institutional review committee (IRC) was taken. The mid part of the pack was collected in a sterile bottle under aseptic technique and sent to microbiology department. Specimen collection, culture, identification tests were done according to the guidelines by American Society for Microbiology. Data were collected using the individual patient records and Microsoft Office Excel 2007. Statistical analysis was performed with SPSS 16.0. Result Among the 51 cultures; 33 (64.7%) were positive. In 18 (35.3%) cultures no organism was grown. Statistical analysis did not show significance between duration of pack kept with microbial growth (p=0.051) or the type of pack kept (p=0.212) .It showed significance with foul smell of the pack to the growth (p <0.001). Conclusion Microbiological flora was associated with nasal pack. Antibiotic soaked nasal packs have lesser incidence of positive bacterial growth when compared with plain nasal packs. Nasal packs kept for less than 48 hours have lesser incidence of positive bacterial growth when compared with nasal packs kept for more than 48 hours. Therefore, administering systemic antibiotics in cases when we plan to keep the pack for longer duration is recommended.

Intravenous midazolam in doses of between 0.07 mg/kg and 0.1 mg/kg has been recommended for sedation in dentistry and some medical procedures and investigations. This study examined the variable sensitivity of patients to midazolam. One hundred and thirty-four fit but anxious patients between the ages of 16 and 63 years received midazolam intravenously for sedation for minor oral surgery. Doses required ranged from 0.04 to 0.40 mg/kg. Nineteen patients required doses less than 0.07 mg/kg; 59 patients required doses greater than 0.1 mg/kg. The mean dose per kilogram required for males was significantly less than for females. The wide variation in sensitivity to midazolam is confirmed.

Studies that evaluate the predictors and causes of unplanned re-operation in outpatient plastic surgery. This study retrospectively reviewed the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) and identified all plastic surgery outpatient cases performed in 2011. Multiple logistic regression analysis was utilised to identify independent risk factors and causes of unplanned reoperations. Of the 6749 outpatient plastic surgery cases identified, there were 125 (1.9%) unplanned re-operations (UR). Regression analysis demonstrated that body mass index (BMI, OR = 1.041, 95% CI = 1.019-1.065), preoperative open wound/wound infection (OR = 3.498, 95% CI = 1.593-7.678), American Society of Anesthesiologists (ASA) class 3 (OR = 2.235, 95% CI = 1.048-4.765), and total work relative value units (RVU, OR = 1.014, 95% CI = 1.005-1.024) were significantly predictive of UR. Additionally, the presence of any complication was significantly associated with UR (OR = 15.065, 95% CI = 5.705-39.781). In an era of outcomes-driven medicine, unplanned re-operation is a critical quality indicator for ambulatory plastic surgery facilities. The identified risk factors will aid in surgical planning and risk adjustment.

The objective of this study was to evaluate safety, cost effectiveness and patient acceptability, of performing a wide variety of gynaecological procedures, including endometrial resections, in a clinic using only local analgesia. Eight hundred and seventeen consecutive gynaecological procedures were performed under local analgesia only, with no sedation, including endometrial resections, cone biopsies, terminations of pregnancy, hysteroscopies, and local vaginal and plastic vulval procedures, as well as many combined procedures (figure 1) in a day-surgery ward annexe in the Department of Gynaecology, St John's District General Hospital, Chelmsford Essex. The main outcome measures were patient acceptability, safety and encountered side-effects of procedures performed under local analgesia as well as evaluation of cost-effectiveness and reduction in theatre waiting list times. A high degree of safety and patient acceptability was achieved, with other considerable benefits being short waiting times and much quicker recovery. The only complications were from the endometrial resection group, with only 8 (3.6%) of these requiring intravenous sedation intraoperatively, and 6 (2.7%) requiring overnight admission. No transfers to theatre during any procedure occurred. Savings per procedure, in cost and in patient's time, were very considerable. The local analgesia approach for a wide variety of gynaecological procedures in a combined outpatient theatre is safe and is highly acceptable to patients. There are also considerable benefits in cost and patient convenience, with a reduction in operating list waiting time, which in the current economic climate are worth considering.

With the purpose of decreasing the existing variability in the criteria of preoperative evaluation and facilitating the clinical decision-making process, our hospital has a protocol of preoperative tests to use with ASA I and ASA II patients. The aim of the study was to calculate the economic impact caused by clinicians' non-adherence to the protocol for the anaesthesiological evaluation of ASA 1 and ASA II patients. A retrospective study of costs with a random sample of 353 patients that were seen in the consultation for Anesthesiology over a period of one year. Aspects related to the costs, patient's profiles and specialties were analysed, according to the degree of fulfillment of the protocol. The lack of adherence to the the protocol was 70%. 130 chest X-rays and 218 ECG were performed without indication. This generated an excess costs of 34 € per patient. Taking into account the expenses of both tests and the attended population undergoing ambulatory surgery during the one-year period, an excess spending for the hospital of between 69.164 € and 83.312 € was estimated. Clinical variability should be reduced and the creation of synergies between the different departments should be enhanced in order to adjust the request for unnecessary complementary tests to decrease health care and to improve the quality of patient care.

Purpose Prevention of cough during emergence after nasal surgery is important for avoiding surgical site bleeding. We investigated the remifentanil effect-site concentration in 50% (EC50) of the elderly patients undergoing nasal surgery for smooth emergence without cough and compared it with that of adult patients. Methods Twenty-two elderly (aged 65–80 years) and 25 adult patients (aged 20–60 years) with an American Society of Anesthesiologists physical status I/II undergoing nasal surgery were enrolled. Anesthesia was maintained with sevoflurane and remifentanil. Remifentanil EC50 and EC95 for preventing cough were determined using the modified Dixon’s up-and-down method and isotonic regression with bootstrapping approach. Recovery profiles were also recorded. Results With Dixon’s up-and-down method, the EC50 of remifentanil in elderly patients (2.40±0.25 ng/mL) was not significantly different from that of adults (2.33±0.30 ng/mL) (P=0.687). With isotonic regression, the EC95 of remifentanil in elderly patients (3.32 [95% confidence interval: 3.06–3.38] ng/mL) was not significantly different from that of adults (3.30 [95% confidence interval: 2.96–3.37] ng/mL). However, eye opening time (14.1±3.8 vs 12.0±2.9 seconds), extubation time (17.2±4.1 vs 14.0±3.0 seconds), and postanesthesia care unit duration (44.5±7.6 vs 38.7±3.4 minutes) in elderly patients were significantly longer than those in adults (P<0.05). Conclusion Remifentanil EC50 for preventing cough after nasal surgery with sevoflurane anesthesia did not differ between elderly and adult patients. However, delayed awakening and respiratory adverse events may warrant attention in elderly patients. PMID:27672319

Nasal polyps are smooth outgrowths assuming a shape of grapes, formed from the nasal mucosa, limiting air flow by projecting into a lumen of a nasal cavity. Up to now the surgical resection is the best method of their treatment, but etiology and pathogenesis of the nasal polyps is not yet fully established. The aim of the study was the assessment of the selected lysosomal exoglycosidases activity in the nasal polyps. In this study the activity of β-galactosidase, α-mannosidase and α-fucosidase was determined in the tissue of the nasal polyps obtained from 40 patients (10F, 30M) and control tissues derived from mucosa of lower nasal conchas obtained during mucotomy from 20 patients (10F, 10M). We observed significant lower values of GAL, FUC and tendency to decrease of MAN and GLU concentration in nasal polyps (P) in comparison to control healthy nasal mucosa (C). In nasal polyp tissue (P) no differences of GAL, MAN and FUC specific activity in comparison to control mucosa (C) were found. Our research supports bioelectrical theory of the nasal polyps pathogenesis and directs attention at research on glycoconjugates and glycosidases of the nasal mucosa extracellular matrix.

We present an audit of primary cleft palate surgery in our unit including rates of two important post-operative complications. Multidisciplinary audit clinics ran from March 1998 to April 2002 to follow up all local patients with a cleft lip or palate who had undergone primary palatal surgery in our unit. One hundred and forty eight patients were studied. Patient ages at follow-up ranged from 3 years and 10 months to 17 years and 4 months. Two surgeons performed the primary surgery. One hundred and twenty eight Wardill-Kilner and 20 Von Langenbeck repairs were performed. We found a 4.7% rate of oro-nasal fistula development requiring surgical closure, and a 26.4% rate of velopharyngeal insufficiency (VPI) requiring subsequent pharyngoplasty. We noted that the type of cleft involved affected the rate of VPI, 16% of patients with unilateral cleft lip and palate versus 29.2% of patients with a solitary cleft palate requiring secondary surgery. Outcome of surgery was determined by a 'Cleft Audit Protocol for Speech' (CAPS) speech therapy assessment at follow-up clinics. Only 14.9% of all patients assessed demonstrated any degree of hypernasality.

To investigate the conjunctival and nasal flora and the antibiotic susceptibility profiles of isolates from patients undergoing cataract surgery. Observational and cross-sectional study. A single-centre study in Taiwan. 128 consecutive patients precataract surgery. Conjunctival and nasal cultures were prospectively obtained from 128 patients on the day of cataract surgery before instillation of ophthalmic solutions in our hospital. Isolates and antibiotic susceptibility profiles were identified through standard microbiological techniques. Participants were asked to complete a questionnaire on healthcare-associated factors. The positive culture rate from conjunctiva was 26.6%, yielding 84 isolates. Coagulase-negative Staphylococci were the most commonly isolated organisms (45.2%), and 35% of staphylococcal isolates were methicillin-resistant. Among staphylococcal isolates, all were susceptible to vancomycin, and 75%-82.5% were susceptible to fluoroquinolones. Methicillin-resistant isolates were significantly less susceptible than their methicillin-sensitive counterparts to tobramycin, the most commonly used prophylactic antibiotic in our hospital (28.6% vs 69.2%; p=0.005). The positive culture rate from nares for Staphylococcus aureus was 21.9%, and six isolates were methicillin-resistant. No subjects had S. aureus colonisation on conjunctiva and nares simultaneously. There were no associated risk factors for colonisation of methicillin-resistant Staphylococci. CONCLUSION: The most common conjunctival bacterial isolate of patients undergoing cataract surgery was coagulase-negative Staphylococci in Taiwan. Because of predominant antibiotic preferences and selective antibiotic pressures, Staphylococci were more susceptible to fluoroquinolones but less to tobramycin than in other reports. Additionally, methicillin-resistant Staphylococci exhibited co-resistance to tobramycin but not to fluoroquinolones. © Article author(s) (or their employer(s) unless otherwise stated

We used a computational fluid dynamics (CFD) model to study the inspiratory airflow profiles of patients with anterior nasal cavity stenosis who underwent curative surgery, by comparing pre- and postoperative airflow characteristics. Twenty patients with severe anterior nasal cavity stenosis, including one case of bilateral stenosis, underwent computed tomography (CT) scans for CFD modelling. The pre- and postoperative airflow characteristics of the nasal cavity were simulated and analyzed. The narrowest area of the nasal cavity in all 20 patients was located within the nasal valve area, and the mean cross-sectional area increased from 0.39 cm2 preoperative to 0.78 cm2 postoperative (P<0.01). Meanwhile, the mean airflow velocity in the nasal valve area decreased from 6.19 m/s to 2.88 m/s (P<0.01). Surgical restoration of the nasal symmetry in the bilateral nasal cavity reduced nasal resistance in the narrow sides from 0.24 Pa.s/mL to 0.11 Pa.s/mL (P<0.01). Numerical simulation of the nasal cavity in patients with anterior nasal cavity stenosis revealed structural changes and the resultant patterns of nasal airflow. Surgery achieved balanced bilateral nasal ventilation and decreased nasal resistance in the narrow region of the nasal cavity. The correction of nasal valve stenosis is not only indispensable for reducing nasal resistance, but also the key to obtain satisfactory curative effect.

The objective of the study is to investigate the impact of receiving daily WeChat services on one's cell phone on adherence to corticosteroid nasal spray treatment in chronic rhinosinusitis (CRS) patients after functional endoscopic sinus surgery (FESS). This study was a two-arm, randomized, follow-up investigation. Patients with chronic rhinosinusitis with/without nasal polyps following bilateral FESS were randomised to receive, or to not receive, daily WeChat service on their cell phone to take corticosteroid nasal spray treatment. A prescription of budesonide aqueous nasal spray 128 µg bid was given to all the subjects. Then they returned to the clinic after 30, 60, 90 days. The primary study outcome was adherence to nasal spray treatment, whereas secondary outcomes were change in endoscopic findings and SinoNasal Outcome Test-20 (SNOT-20). On the whole, there was a significant inter-group difference in the change of adherence rate (F = 90.88, p = 0.000). The WeChat group had much higher adherence rate than the control group during the follow-up. In terms of postoperative endoscopic scores and SNOT-20, except granulation score, no significant differences were observed between the two randomization groups. WeChat services are already after a short period of observation associated with improved adherence to corticosteroid nasal spray treatment in CRS patients after FESS.

Nasal polyps occur in 1-4% of the population, usually occurring in the setting of an underlying local or systemic disease. The most common associated condition is chronic rhinosinusitis (CRS). A high prevalence of nasal polyps is also seen in allergic fungal rhinosinusitis, aspirin-exacerbated respiratory disease, Churg-Strauss syndrome, and cystic fibrosis. In the setting of CRS, nasal polyps are not likely to be cured by either medical or surgical therapy; however, control is generally attainable. The best medical evidence supports the use of intranasal corticosteroids for maintenance therapy and short courses of oral corticosteroids for exacerbations. The evidence for short- and long-term antibiotics is much less robust. For patients with symptomatic nasal polyposis nonresponsive to medical therapies, functional endoscopic sinus surgery provides an adjunctive therapeutic option.

Complex surgical procedures are increasingly performed in an outpatient setting, with emphasis on rapid recovery and case turnover. In this study, the combination of rocuronium for neuromuscular blockade (NMB) reversed by single-dose sugammadex was compared with succinylcholine followed by spontaneous recovery in outpatient surgery. This multicenter, randomized, safety assessor-blinded study enrolled adults undergoing a short elective outpatient surgical procedure requiring NMB and tracheal intubation. Patients were randomized to NMB with either rocuronium 0.6 mg/kg for tracheal intubation with incremental doses of rocuronium 0.15 mg/kg and subsequent reversal with sugammadex 4.0 mg/kg at 1-2 posttetanic counts or succinylcholine 1.0 mg/kg for intubation with spontaneous recovery. The primary efficacy end point was the time from sugammadex administration to recovery of the train-of-four ratio to 0.9; for succinylcholine, time from administration to recovery of the first twitch (T1) to 90% was assessed. From 167 patients enrolled, 150 received treatment. The all-subjects-treated population comprised 70 patients in the rocuronium-sugammadex group and 80 in the succinylcholine group. Geometric mean (95% confidence interval) time from the start of sugammadex administration to recovery of the train-of-four ratio to 0.9 was 1.8 (1.6-2.0) minutes. Geometric mean (95% confidence interval) time from succinylcholine administration to recovery of T1 to 90% was 10.8 (10.1-11.5) minutes. Health outcome variables were similar between the groups. Adverse events were reported in 87.1% and 93.8% of patients for rocuronium-sugammadex and succinylcholine, respectively. In conclusion, rocuronium for intubation followed by sugammadex for reversal of NMB offers a viable treatment option in outpatient surgery without prolonging recovery duration or jeopardizing safety.

The time-driven activity-based costing (TD-ABC) method is a novel approach to quantify the costs of a complex system. The aim of this study was to apply the TD-ABC technique to define the overall cost of a routine outpatient endoscopic sinus surgery (ESS) from the perspective of the Canadian government payer. Costing perspective was the Canadian government payer. All monetary values are in Canadian dollars as of December 2012. Costs were obtained by contacting staff unions, reviewing purchasing databases and provincial physician fee schedules. Practical capacity time values were collected from the College and Association of Registered Nurses of Alberta. Capacity cost rates ($/min) were calculated for all staff, capital equipment, and hospital space. The overall cost for routine outpatient ESS was $3510.31. The cost per ESS case for each clinical pathway encounter was as follows: preoperative holding ($49.19); intraoperative ($3296.60); sterilization ($90.20); postanesthesia care unit ($28.64); and postoperative day ward ($45.68). The 3 major cost drivers were physician fees, disposable equipment, and nursing costs. The intraoperative phase contributed to 94.5% of the overall cost. This study applied the TD-ABC method to evaluate the cost of outpatient ESS from the perspective of the Canadian government payer and defined the overall cost to be $3510.31 per case. © 2013 ARS-AAOA, LLC.

The employment of a diversity of prosthetic materials and several types of mesh different in construction is opening a new chapter in hernia surgery and tension-free techniques are becoming a "golden standard" for repairing abdominal wall defects, whereas the conventional methods, i.e., the tension techniques are performed on young patients having small direct, indirect, or femoral hernias. The aim of this retrospective study is to present the results of using Prolene Hernia System (PHS), Ultrapro Hernia System (UHS) and 3D Patch (3DP) devices in the treatment of inguinal, femoral, umbilical and small incisional hernias in outpatient surgery. From January 2006 to January 2009, 70 patients were operated on for abdominal wall hernias (54 inguinal, 4 femoral, 8 umbilical and 4 small incisional hernias) using PHS, UHS and 3DP devices. All the patients underwent surgery under local infiltrative anaesthesia. All the surgical operations were performed by a single surgeon, 19 of them in the General Hospital and 51 in a private polyclinic. The mean size of the hernia defect in the inguinal, femoral and umbilical hernias was 2.5 cm (1-4 cm), while in the incisional hernias it was 4.5 cm (3-6 cm). The mean operating time was 2.4 hrs (2-6 hrs). There were no requirement for urinary drains. The mean follow-up was 18 months (0-36 months). The incidence of infection, chronic pain and recurrence was 0%. Three of the patients had complications: seroma in one patient with an incisional hernia and hematoma in two patients after inguinal hernia repair. The employment of PHS, UHS and 3DP devices, which have not yet been widely accepted in our hospitals, has had outstanding results in outpatient surgery. In addition, the type of anaesthesia and the 3D mesh construction prepare the way for a short hospital stay, smooth recovery and a swift return to normal activity.

Computational fluid dynamics (CFD) is a mathematical tool to analyse airflow. We present a novel CFD software package to improve results following nasal surgery for obstruction. A group of engineers in collaboration with otolaryngologists have developed a very intuitive CFD software package called MeComLand®, which uses the patient's cross-sectional (tomographic) images, thus showing in detail results originated by CFD such as airflow distributions, velocity profiles, pressure, or wall shear stress. NOSELAND® helps medical evaluation with dynamic reports by using a 3D endoscopic view. Using this CFD-based software a patient underwent virtual surgery (septoplasty, turbinoplasty, spreader grafts, lateral crural J-flap and combinations) to choose the best improvement in nasal flow. To present a novel software package to improve nasal surgery results. To apply the software on CT slices from a patient affected by septal deviation. To evaluate several surgical procedures (septoplasty, turbinectomy, spreader-grafts, J-flap and combination among them) to find the best alternative with less morbidity. The combination of all the procedures does not provide the best nasal flow improvement. Septoplasty plus turbinoplasty obtained the best results. Turbinoplasty alone rendered almost similar results to septoplasty in our simulation. CFD provides useful complementary information to cover diagnosis, prognosis, and follow-up of nasal pathologies based on quantitative magnitudes linked to fluid flow. MeComLand®, DigBody® and NoseLand® represent a non-invasive, low-cost alternative for the functional study of patients with nasal obstruction.

In this paper we present our procedure for the treatment, histopathological diagnosis, and resection of skin cancer in the nasal pyramid and its subsequent reconstruction. Because we are dealing with the most important anatomical feature of the face our goal is an aesthetic reconstruction [2,4] according to the anatomical subunits criterion of Burget . First, a histopathological diagnosis is made to determine the nature of the tumor. Then, we proceed with the resection according to the Mohs Micrographic Surgery [1,5,7]. Then we begin with the first step of the nasal reconstruction.

Parenteral opioids are the standard of care for treating moderate to severe postsurgical pain. This randomized, double-blind, dose-ranging study compared the safety and efficacy of intranasal (IN) morphine with intravenous (IV) morphine and placebo. In total, 187 postbunionectomy patients with moderate to severe pain were randomized to receive IN morphine 3.75 mg, 7.5 mg, 15 mg, or 30 mg, IV morphine 7.5 mg, or placebo in the single-dose phase and IN morphine 7.5 mg or 15 mg thereafter. The primary outcome was a dose-response assessment for total pain relief based upon visual analog scales. Secondary endpoints included pain intensity, pain relief, patient global evaluation, and time to rescue medication. Safety assessments included adverse events and nasal examination. A statistically significant linear dose response was observed over the IN morphine dose range for 4-hour total pain relief. Patients reported statistically significant pain relief and pain intensity differences following IV morphine and IN morphine at doses of 7.5 mg and greater within 30 minutes postdose, compared with placebo. Median times to rescue medication were 124 and 140 minutes for IN morphine 7.5 mg and 15 mg dosage groups, respectively, and 130 minutes for IV morphine. Local adverse events associated with IN morphine were transient and mostly mild (bad taste, nasal congestion, throat irritation, and sneezing). Systemic adverse events, regardless of route of administration, were dose-related and consistent with expected opioid effects. By multiple measures of pain intensity and pain relief, IN morphine provides sustained analgesia in postsurgical patients and thus may offer a safe and less invasive alternative to IV morphine.

Prophylactic antibiotics have been shown to prevent surgical site infection (SSI) after some gastrointestinal, orthopedic, and plastic surgical procedures, but their efficacy in clean, elective hand surgery is unclear. Our aims were to assess the efficacy of preoperative antibiotics in preventing SSI after clean, elective hand surgery, and to identify potential risk factors for SSI. We queried the database from an outpatient surgical center by Current Procedural Terminology code to identify patients who underwent elective hand surgery. For each medical record, we collected patient demographics and characteristics along with preoperative, intraoperative, and postoperative management details. The primary outcome of this study was SSI, and secondary outcomes were wound dehiscence and suture granuloma. From October 2000 through October 2008, 8,850 patient records met our inclusion criteria. The overall SSI rate was 0.35%, with an average patient follow-up duration of 79 days. The SSI rates did not significantly differ between patients receiving antibiotics (0.54%; 2,755 patients) and those who did not (0.26%; 6,095 patients). Surgical site infection was associated with smoking status, diabetes mellitus, and longer procedure length irrespective of antibiotic use. Subgroup analysis revealed that prophylactic antibiotics did not prevent SSI in male patients, smokers, or diabetics, or for procedure length less than 30 minutes, 30 to 60 minutes, and greater than 60 minutes. Prophylactic antibiotic administration does not reduce the incidence of SSI after clean, elective hand surgery in an outpatient population. Moreover, subgroup analysis revealed that prophylactic antibiotics did not reduce the frequency of SSI among patients who were found to be at higher risk in this study. We identified 3 factors associated with the development of SSI in our study: diabetes mellitus status, procedure length, and smoking status. Given the potential harmful complications associated with

The main issues in nasal surgery are to stabilize the nose in the good position after surgery and preserve the cartilages and bones in the favorable situation and reduce the risk of deviation recurrence. Also it is necessary to avoid the synechia formation, nasal valve narrowing, hematoma and bleeding. Due to the above mentioned problems and in order to solve and minimize them nasal packing, nasal splint and nasal mold have been advised. Patients for whom the nasal packing used may faced to some problems like naso-pulmonary reflex, intractable pain, sleep disorder, post operation infection and very dangerous complication like toxic shock syndrome. We have two groups of patients and three surgeons (one of the surgeons used post operative nasal packing in his patients and the two others surgeons did not).Complications and morbidities were compared in these two groups. Comparing the two groups showed that the rate of complication and morbidities between these two groups were same and the differences were not valuable, except the pain and discomfort post operatively and at the time of its removal. Nasal packing has several risks for the patients while its effects are not studied. Septoplasty can be safely performed without postoperative nasal packing. Nasal packing had no main findings that compensated its usage. Septal suture is one of the procedures that can be used as alternative method to nasal packing. Therefore the nasal packing after septoplasty should be reserved for the patients with increased risk of bleeding.

Patients with a body mass index (BMI) ≥30 kg/m(2) experience more severe atelectasis following cardiac surgery than those with normal BMI and its resolution is slower. This study aimed to compare extubation of patients post-cardiac surgery with a BMI ≥30 kg/m(2) onto high-flow nasal cannulae (HFNC) with standard care to determine whether HFNC could assist in minimising post-operative atelectasis and improve respiratory function. In this randomised controlled trial, patients received HFNC or standard oxygen therapy post-extubation. The primary outcome was atelectasis on chest X-ray. Secondary outcomes included oxygenation, respiratory rate (RR), subjective dyspnoea, and failure of allocated treatment. One hundred and fifty-five patients were randomised, 74 to control, 81 to HFNC. No difference was seen between groups in atelectasis scores on Days 1 or 5 (median scores = 2, p = 0.70 and p = 0.15, respectively). In the 24-h post-extubation, there was no difference in mean PaO2/FiO2 ratio (HFNC 227.9, control 253.3, p = 0.08), or RR (HFNC 17.2, control 16.7, p = 0.17). However, low dyspnoea levels were observed in each group at 8 h post-extubation, median (IQR) scores were 0 (0-1) for control and 1 (0-3) for HFNC (p = 0.008). Five patients failed allocated treatment in the control group compared with three in the treatment group [Odds ratio 0.53, (95 % CI 0.11, 2.24), p = 0.40]. In this study, prophylactic extubation onto HFNC post-cardiac surgery in patients with a BMI ≥30 kg/m(2) did not lead to improvements in respiratory function. Larger studies assessing the role of HFNC in preventing worsening of respiratory function and intubation are required.

Ambulatory surgery is on the rise, with an unmet need for optimum pain control in ambulatory surgery centers worldwide. It is important that there is a proportionate increase in the availability of acute pain-management services to match the rapid rise of clinical patient load with pain issues in the ambulatory surgery setting. Focus on ambulatory pain control with its special challenges is vital to achieve optimum pain control and prevent morbidity and mortality. Management of perioperative pain in the ambulatory surgery setting is becoming increasingly complex, and requires the employment of a multimodal approach and interventions facilitated by ambulatory surgery pain specialists, which is a new concept. A focused ambulatory pain specialist on site at each ambulatory surgery center, in addition to providing safe anesthesia, could intervene early once problematic pain issues are recognized, thus preventing emergency room visits, as well as readmissions for uncontrolled pain. This paper reviews methods of acute-pain management in the ambulatory setting with risk stratification, the utilization of multimodal interventions, including pharmacological and nonpharmacological options, opioids, nonopioids, and various routes with the goal of preventing delayed discharge and unexpected hospital admissions after ambulatory surgery. Continued research and investigation in the area of pain management with outcome studies in acute surgically inflicted pain in patients with underlying chronic pain treated with opioids and the pattern and predictive factors for pain in the ambulatory surgical setting is needed.

To evaluate the impact of FESS in children with chronic rhinosinusitis with nasal polyps, regarding their overall postoperative quality-of-life (QoL) and constituent QoL domains. Potential differences between cystic fibrosis (CF) sufferers and non-sufferers, or cases with recurrent sinonasal polyposis versus single-operations were also explored. 39 children were studied. The mean patient age was 10.9 years; four children suffered from cystic fibrosis. The children (or parents) completed the Glasgow Benefit Inventory for Children (GCBI) at least six months after their operation. The Mann-Whitney test compared the GCBI scores between non- and CF sufferers, as well as children with and without recurrent polyposis. The median overall QoL score was 98. There were no statistically significant differences between CF sufferers and non-sufferers regarding their overall QoL, or the respective individual QoL domains, apart from their physical postoperative activity (p = 0.04). Twelve children demonstrated recurrent polyposis (30.7%); among them three were cystic fibrosis sufferers. No statistically significant differences were identified in the overall QoL score, or individual GCBI subscale scores between children with recurrent polyposis versus single-operations. Children with recurrent polyposis but not CF performed better regarding their overall QoL (p = 0.021) and medical status (p = 0.015), compared to their CF counterparts. FESS performed for chronic rhinosinusitis with nasal polyps in children is associated with improved postoperative QoL, irrespective of the presence of CF (although the latter needs to be confirmed in larger patient cohorts). The absence of appreciable differences in the overall QoL, or its constituent domains, between single and re-operated children, indicate that the positive effect of FESS outweighed the burden of re-operation. Appropriate preoperative informed consent in cases of recurrent sinonasal polyposis necessitates acknowledging worse

Bacterial endophthalmitis is a sight threatening infection of the interior structures of the eye. Incidence in the US has increased in recent years, which appears to be related to procedures being performed on an aging population. The advent of outpatient intravitreal therapy for management of age-related macular degeneration raises yet additional risks. Compounding the problem is the continuing progression of antibiotic resistance. Visual prognosis for endophthalmitis depends on the virulence of the causative organism, the severity of intraocular inflammation, and the timeliness of effective therapy. We review the current understanding of the pathogenesis of bacterial endophthalmitis, highlighting opportunities for the development of improved therapeutics and preventive strategies. PMID:22521570

The cleft nasal deformity is a complex challenge in plastic surgery involving the skin, cartilage, mucosa, and skeletal platform. Ever since Blair and Brown first described the intricacies of the cleft pathology in 1931, the appropriate approach has been extensively debated in the literature with respect to timing, technique, and extent of surgical intervention. In this article, the authors review the literature and summarize the various modalities for achieving a successful rhinoplasty in the patient with a cleft nasal deformity. PMID:24179452

Background The purpose of this two-phase project was to conduct formative evaluation and test the preliminary efficacy of a newly developed web-based, tailored behavioral preparation program (WebTIPS) for children undergoing outpatient surgery and their parents Methods Phase I enrolled 13 children aged 2–7 years undergoing outpatient elective surgery and their parents for formative evaluation of WebTIPS. Parent participation focus groups which are common in qualitative research and are a method of asking research participants about their perceptions and attitudes regarding a product or concept. In phase II, children age 2–7 years in two medical centers were randomly assigned to receive the WebTIPS program (n = 38) compared to children receiving standard of care (n = 44). The primary outcome of phase II was child and parent preoperative anxiety. Results In phase I, parents reported WebTIPS to be both helpful (p < 0.001) and easy to use (p < 0.001). In phase II, children in the WebTIPS group (36.2 ± 14.1) were less anxious than children in the standard of care group (46.0 ± 19.0) at entrance to the operating room (p = 0.02; Cohen’s d = 0.59) and introduction of the anesthesia mask (43.5 ± 21.7 vs. 57.0 ± 21.2, respectively, p = 0.01; Cohen’s d = 0.63). Parents in the WebTIPS group (32.1 ± 7.4) also experienced less anxiety compared to parents in the control group (36.8 ± 7.1) in the preoperative holding area (p = 0.004; Cohen’s d = 0.65). Conclusions WebTIPS was well received by parents and children and led to reductions in preoperative anxiety. PMID:25790213

Traditionally, rhinoseptoplasty for nasal bone fracture is only considered after an unsatisfactory outcome from initial closed reduction. However, better surgical outcomes may be achieved if rhinoseptoplasty is performed at the same time as the nasal bone fracture reduction. This study investigated the surgical outcomes of patients who underwent rhinoseptoplasty concomitantly with nasal bone fracture reduction according to their computed tomography image-based nasal bone fracture classifications. Case series with chart review. Academic tertiary care medical center. Fifty-six patients who underwent rhinoseptoplasty concomitantly with nasal bone fracture reduction were enrolled in this study. Nasal bone fractures were classified into 6 types by computed tomography scans. Two independent facial plastic surgeons evaluated the outcomes 6 months postoperatively using a visual analog scale. The nasal tip projection and rotation were measured using the pre- and postoperative profile views. The satisfaction scores of type I, IIo, and IIIo fractures without septal fracture were significantly higher than those of type II, III, and IV fractures with septal fractures. Among the patients, 82.1% underwent lower vault surgery. The nasal tip projection and rotation were increased after surgery in patients without septal fractures, whereas the tip rotation was elevated but the projection was unchanged postoperatively in patients with septal fractures. Rhinoseptoplasty for acute nasal bone fractures can be performed at the same time as nasal bone fracture reduction. However, nasal bone fracture with septal fracture should be managed carefully.

Costal cartilage is an important reconstructive tissue for correcting nasal deformities. Warping of costal cartilage, a recognized complication, can lead to significant functional and aesthetic problems. The authors present a technique to prevent warping that involves transverse slicing of the sixth-seventh costal cartilaginous junction, that when sliced perpendicular to the long axis of the rib, provides multiple long, narrow, clinically useful grafts with balanced cross-sections. The aim was to measure differences in cartilage warp between this technique (TJS) and traditional carving techniques. Costal cartilage was obtained from human subjects and cut to clinically relevant dimensions using a custom cutting jig. The sixth-seventh costal cartilaginous junction was sliced transversely leaving the outer surface intact. The adjacent sixth rib cartilage was carved concentrically and eccentrically. The samples were incubated and standardized serial photography was performed over time up to 4 weeks. Warp was quantified by measuring nonlinearity of the grafts using least-squares regression and compared between carving techniques. TJS grafts (n = 10) resulted in significantly less warp than both eccentrically (n = 3) and concentrically carved grafts (n = 3) (P < 0.0001). Warp was significantly higher with eccentric carving compared with concentric carving (P < 0.0001). Warp increased significantly with time for both eccentric (P = 0002) and concentric (P = 0.0007) techniques while TJS warp did not (P = 0.56). The technique of transverse slicing costal cartilage from the sixth-seventh junction minimizes warp compared with traditional carving methods providing ample grafts of adequate length and versatility for reconstructive requirements.

Bilateral cleft lip nose deformity is a multi-factorial and complex deformity which tends to aggravate with growth of the child, if not attended surgically. The goals of primary bilateral cleft lip nose surgery are, closure of the nasal floor and sill, lengthening of the columella, repositioning of the alar base, achieving nasal tip projection, repositioning of the lower lateral cartilages, and reorienting the nares from horizontal to oblique position. The multiplicity of procedures in the literature for correction of this deformity alludes to the fact that no single procedure is entirely effective. The timing for surgical intervention and its extent varies considerably. Early surgery on cartilage may adversely affect growth and development; at the same time, allowing the cartilage to grow in an abnormal position and contributing to aggravation of deformity. Some surgeons advocate correction of deformity at an early age. However, others like the cartilages to grow and mature before going in for surgery. With peer pressure also becoming an important consideration during the teens, the current trend is towards early intervention. There is no unanimity in the extent of nasal dissection to be done at the time of primary lip repair. While many perform limited nasal dissection for the fear of growth retardation, others opt for full cartilage correction at the time of primary surgery itself. The value of naso-alveolar moulding (NAM) too is not universally accepted and has now more opponents than proponents. Also most centres in the developing world have neither the personnel nor the facilities for the same. The secondary cleft nasal deformity is variable and is affected by the extent of the original abnormality, any prior surgeries performed and alteration due to nasal growth. This article reviews the currently popular methods for correction of nasal deformity associated with bilateral cleft lip, it's management both at the time of cleft lip repair and also secondarily

Although the successful use of the Ho:YAG laser in nasal turbinate surgery had been reported no clinical study had been performed to assess the clinical outcome in longterm. By means of a pulsed Ho:YAG laser emitting at λ=2080nm (1J/pulse, 3-8 Hz) 57 patients suffering from nasal obstruction due to allergic rhinitis and vasomotoric rhinitis were treated under local anesthesia. The study was conducted by standardized questionnaire, photo documentation, allergy test, mucocilliar test, rhinomanometry, radiology and histology. Within 2 weeks after laser treatment a significant improvement of nasal airflow correlating to the extent of the ablated turbinate tissue could be determined. This effect lasted up until 1 year post treatment resulting in an improved quality of life in more than 80 percent of the patients. Side effects like nasal dryness and pain were rare (<4%), no immediate complications were observed. The total treatment time takes 3-8 min and nasal packing was not necessary after the laser procedure. In conclusion Ho:YAG laser treatment can be performed as an outpatient procedure under local anesthesia with excellent ablation of soft tissue in a short treatment time with promising results.

To evaluate the effect of pre-operative octenidine (OCT) decolonization on surgical site infection (SSI) rates. Before-and-after cohort study. Patients undergoing an elective isolated coronary artery bypass graft (CABG) procedure: control group (1(st) January to 31(st) December 2013), N=475; intervention group (1(st) January to 31(st) December 2014), N=428. The intervention consisted of nasal application of OCT ointment three times daily, beginning on the day before surgery, and showering the night before and on the day of surgery with OCT soap. A median sternotomy was performed in 805 (89.1%) patients and a minimally invasive direct coronary artery bypass procedure was performed in 98 (10.9%) patients. Overall, there was no difference in SSI rates between the control and intervention groups (15.4% vs 13.3%, P=0.39). The rate of harvest site SSIs was significantly lower in patients in the intervention group (2.5% vs 0.5%, P=0.01). Patients who had undergone a median sternotomy in the intervention group had a significantly lower rate of organ/space sternal SSIs (1.9% vs 0.3%, P=0.04). However, there was a trend towards an increased rate of deep incisional sternal SSIs (1.2% vs 2.9%, P=0.08). Multi-variate analysis did not identify a significant protective effect of the intervention (odds ratio 0.79, 95% confidence interval 0.53-1.15, P=0.27). Pre-operative decolonization with OCT did not reduce overall SSI rates in patients undergoing an elective isolated CABG procedure, but significantly decreased harvest site and organ/space sternal SSIs. Randomized controlled trials, including controlled patient adherence to the intervention, are required to confirm these observations and to determine the clinical utility of OCT in pre-operative decolonization.

Objectives Speech intelligibility is severely affected in children with congenital profound hearing loss. Hypernasality is a problem commonly encountered in their speech. Auditory information received from cochlear implants is expected to be far superior to that from hearing aids. Our study aimed at comparing the percentages of nasality in the speech of the cochlear implantees with hearing aid users and also with children with normal hearing. Methods Three groups of subjects took part in the study. Groups I and II comprised 12 children each, in the age range of 4-10 years, with prelingual bilateral profound hearing loss, using multichannel cochlear implants and digital hearing aids respectively. Both groups had received at least one year of speech therapy intervention since cochlear implant surgery and hearing aid fitting respectively. The third group consisted of age-matched and sex-matched children with normal hearing. The subjects were asked to say a sentence which consisted of only oral sounds and no nasal sounds ("Buy baby a bib"). The nasalance score as a percentage was calculated. Results Statistical analysis revealed that the children using hearing aids showed a high percentage of nasalance in their speech. The cochlear implantees showed a lower percentage of nasalance compared to children using hearing aids, but did not match with their normal hearing peers. Conclusion The quality of speech of the cochlear implantees was superior to that of the hearing aid users, but did not match with the normal controls. The study suggests that acoustic variables still exist after cochlear implantation in children, with hearing impairments at deviant levels, which needs attention. Further research needs to be carried out to explore the effect of the age at implantation as a variable in reducing nasality in the speech and attaining normative values in cochlear implantees, and also between unilateral versus bilateral implantees.

Context: Nasal cleft deformity is a complicated problem. Utilization of nasal stent in post septorhinoplastyaims at establishing and maintaining airway patency, tissue position, and reduces tissue contracture after surgery. Case Report: A 16-year-old female patient presented with history of surgical reconstruction of congenital cleft lip and cleft palate with secondary septorhinoplasty of nasal cleft deformity. Patient was referred for nasal stent 1 week after septorhinoplasty. This case report provides a novel technique for fabrication of esthetic nasal stent after postseptorhinoplasty for secondary cleft nose deformity correction. Conclusion: This case report presents a simple, convenient technique for nasal stent fabrication for prevention of restenosis for cleft nose deformity post secondary septorhinoplasty. Provision of nasal stent allows breathing, maintains esthetics, comfort, nasal patency, and contour with minimal discomfort. PMID:25789253

To study the pulmonary function and nasal resistance characteristics of patients with chronic nose-sinusitis and nasal polyps (CRSwNP), to explore the evaluation role of nasal resistance in nasal ventilation function and the effect of endoscopic sinus surgery on pulmonary function in patients with CRSwNP. Fifty CRSwNP patients that met the study criteria were selected . The patients were performed endoscopic surgeries according to Messerklinger surgical procedures under general anesthesia. Extent of surgery was based on preoperative CT showing the range of the lesion of disease and endoscopic findings. Perioperative treatments contained intranasal corticosteroids, cephalosporin or penicillin antibiotics, nasal irrigation and other treatments. Main outcome measures included visual analog scale (VAS), endoscopic Lind-Kennedy scores, nasal resistence, pulmonary function in patientsone week before and after surgery, three months and six months after surgery. Pulmonary function includes forced expiratory volume in one second (FEV1), forced vital capacity FEV1/FVC and peak expiratory flow (PEF). The study found that there were significantly positive correlations among VAS score, Lund-Kennedy score and nasal resistance (P < 0.05) in CRSwNP patients, but there is a significantly negative correlation between VAS score, Lund-Kennedy score, nasal resistance and pulmonary function indexes of FEV1, FVC and PEF (P < 0.05). The VAS score, Lund-Kennedy score and nasal resistance values of CRSwNP patients were decreased significantly after comprehensive treatments with nasal endoscopic operation as the major one, the difference was statistically different (P < 0.05). And the pulmonary function indexs (FEV1, FVC, PEF) were significantly increased after surgery in CRSwNP patients. The nasal resistance can objectively and reliably reflect the degree of nasal congestion and the recovery of nasal function in CRSwNP patients after endoscopic sinus surgery.

The nasal cycle represents a significant challenge when comparing pre- and post-surgery objective measures of nasal airflow. Computational fluid dynamics (CFD) simulations of nasal airflow were conducted in 12 nasal airway obstruction patients showing significant nasal cycling between pre- and post-surgery computed tomography scans. To correct for the nasal cycle, mid-cycle models were created virtually. Subjective scores of nasal patency were obtained via the Nasal Obstruction Symptom Evaluation (NOSE) and unilateral visual analog scale (VAS). The correlation between objective and subjective measures of nasal patency increased after correcting for the nasal cycle. In contrast to biophysical variables in individual patients, cohort averages were not significantly affected by the nasal cycle correction. The ability to correct for the confounding effect of the nasal cycle is a key element that future virtual surgery planning software for nasal airway obstruction will need to account for when using anatomic models based on single instantaneous imaging.

Suturing of the nasal septum after septal surgery is a commonly performed procedure designed to prevent complications such as septal haematoma and bleeding. It is also useful for closing any inadvertent tears of the septal mucosa and providing additional support for the cartilage pieces retained in septoplasty. In addition, the suture can be placed through the middle turbinates, stabilising them during the healing process. Placing knots for interrupted sutures in the posterior and middle part of the nasal septum can be technically difficult. We describe a continuous suturing technique for approximating the mucosal flaps following septal surgery.

Fibromyalgia (FM) is a chronic pain syndrome characterized by generalized pain. It is known that obese patients have more skeletal muscle pain and physical dysfunction than normal weight patients. Therefore, it is important that the early diagnosis of FM be attained in obese patients. To determine the prevalence of FM in a group of obese patients with indication of bariatric surgery. The patients were recruited from the Bariatric Surgery outpatient clinic of Hospital de Clínicas of UFPR (HC-UFPR) before being submitted to surgery. Patient assessment consisted in verifying the presence or absence of FM using the 1990 and 2011 ACR criteria, as well as the presence of comorbidities. 98 patients were evaluated, of which 84 were females. The mean age was 42.07 years and the BMI was 45.39. The prevalence of FM was 34% (n=29) according to the 1990 criteria and 45% (n=38) according to the 2011 criteria. There was no difference in age, BMI, Epworth score and prevalence of other diseases among patients who met or not the 1990 criteria. Only depression was more common in patients with FM. (24.14% vs. 5.45%). The same findings were seen in patients that met the 2011 criteria. The prevalence of FM in patients with morbid obesity is extremely high. However, BMI does not differ in patients with or without FM. The presence of depression may be a risk factor for the development of FM in these patients. Copyright © 2017.

Although nitrous oxide (N2O) is used commonly during anesthesia, clinically relevant advantages-disadvantages of using this agent are not well established in the ambulatory setting. This study in women undergoing ambulatory gynecologic surgery compares outcomes in patients administered total intravenous anesthesia with propofol versus the propofol plus N2O. The primary outcome was the time to home readiness. Secondary outcomes included the incidence of postanesthetic adverse events. Women presenting for elective ambulatory termination of pregnancy or gynecologic laparoscopy were induced with an intravenous sleep dose of propofol and fentanyl. After induction, subjects were randomly allocated to maintenance anesthesia with propofol alone or propofol plus 65% N2O. Patients were assessed by a blinded observer in the postanesthetic care unit at 20-min intervals to determine home readiness. Postoperative pain and nausea were measured with visual analog scales. Postoperative analgesics and antiemetics were recorded. The incidence of adverse events occurring after hospital discharge was assessed by a telephone interview 24 h postoperatively. A total of 740 patients received propofol alone, and 750 patients received propofol plus N2O. Mean home readiness times were not significantly different between treatment groups. There were no significant differences between groups in pain scores, nausea scores, analgesia administration, or antiemetic administration before discharge. There were no significant differences in the frequency of adverse events for 24 h after discharge from hospital. Omission of N2O from a propofol-based anesthetic for ambulatory gynecologic surgery does not affect time to home readiness or the incidence of postoperative adverse events up to 24 h after discharge from hospital. (Key words: Awareness; outpatient surgery; total intravenous anesthesia.)

We have always been searching for the ideal local anesthetic for outpatient spinal anesthesia. Lidocaine has been associated with a high incidence of transient neurological symptoms, and bupivacaine produces sensory and motor blocks of long duration. Preservative-free 2-chloroprocaine (2-CP) seems to be a promising alternative, being a short-acting agent of increasing popularity in recent years. This study was designed to compare 2-CP with bupivacaine for spinal anesthesia in an elective ambulatory setting. A total of 106 patients were enrolled in this randomized double-blind study. Spinal anesthesia was achieved with 0.75% hyperbaric bupivacaine 7.5 mg (n = 53) or 2% preservative-free 2-CP 40 mg (n = 53). The primary endpoint for the study was the time until reaching eligibility for discharge. Secondary outcomes included the duration of the sensory and motor blocks, the length of stay in the postanesthesia care unit, the time until ambulation, and the time until micturition. The average time to discharge readiness was 277 min in the 2-CP group and 353 min in the bupivacaine group, a difference of 76 min (95% confidence interval [CI]: 40 to 112 min; P < 0.001). The average time for complete regression of the sensory block was 146 min in the 2-CP group and 329 min in the bupivacaine group, a difference of 185 min (95% CI: 159 to 212 min; P < 0.001). Times to ambulation and micturition were also significantly lower in the 2-CP group. Spinal 2-chloroprocaine provides adequate duration and depth of surgical anesthesia for short procedures with the advantages of faster block resolution and earlier hospital discharge compared with spinal bupivacaine.

The aim of this study is to report our preliminary experiences with regard to safety and feasibility of three-dimensional (3D) endoscopic lacrimal surgeries with a recently launched latest generation 3D endoscope. A 4-mm rigid three-dimensional (3D) endoscope (TIPCAM 1S 3D ORL(R), Karl Storz, Tuttlingen, Germany) was used. Fifteen patients who underwent various endoscopic lacrimal procedures by a single surgeon (MJA) were included. The procedures included probing with nasolacrimal intubation, cruciate marsupialization of intranasal cysts for congenital dacryoceles, powered endoscopic dacryocystorhinostomy, post-operative stent removal with ostium granuloma excision. The implementation, visualization, optical performance, ease of tissue handling and complications were noted. Ten surgical observers filled a questionnaire to rate their experiences. Enhanced depth perception was found to be very beneficial intraoperatively. Greater anatomical delineation facilitated improved hand-eye coordination and dexterity. Intraoperative assessment and handling of tissues and surgical manoeuvring were precise and did not require the additional spatial cues that the surgeon derives from a two-dimensional image. These benefits were more appreciated in the complex cases. The setup was easy on previous endoscopic platforms and did not consume any additional time. All the surgical procedures were completed successfully without any complications. The surgical observers unanimously noted enhanced anatomical understanding and surgical learning as compared to the routine 2D planes. Operating in 3D planes enhances depth perception, dexterity and precision. Although initial results are promising, further randomized studies with head-on comparisons between 3D and 2D would help formulate specific guidelines.

Capnometry detects hypoventilation earlier than pulse oximetry while supplemental oxygen is being administered. We compared the end-tidal CO2 (PETCO2 ) measured using a newly developed oxygen nasal cannula with a CO2-sampling port and the PaCO2 in extubated subjects after abdominal surgery. We also investigated whether the difference between PaCO2 and PETCO2 is affected by resting, by spontaneous breathing with the mouth consciously closed, and by deep breathing with the mouth closed. Adult post-abdominal surgery subjects admitted to the ICU were enrolled. After extubation, oxygen was supplied at 4 L/min using a capnometry-type oxygen cannula. The breathing frequency, PETCO2 , and PaCO2 were measured after 30 min of oxygen supplementation. PETCO2 was continuously measured during rest, during breathing with the mouth consciously closed, and during deep breathing with the mouth closed. The difference between PETCO2 and PaCO2 during various breathing patterns was analyzed using the Bland-Altman method. Twenty subjects were included. The bias ± SD (limits of agreement) for breathing frequency measured by capnometry compared with those obtained by direct measurement was 0.4 ± 3.6 (-6.7 to 7.4). In PETCO2 compared with PaCO2 , the biases (limits of agreement) were 14.8 ± 8.2 (-1.3 to 30.9) at rest, 10.2 ± 6.4 (-2.3 to 22.7) with the mouth closed, and 7.7 ± 5.6 (-3.2 to 18.6) for deep breathing with the mouth closed. PETCO2 determined using the capnometry device yielded unreliable and widely ranging values under various breathing patterns. However, deep breathing with the mouth closed decreased the difference between PETCO2 and PaCO2 , as compared with other breathing patterns. PETCO2 measurements under deep breathing with mouth closed with a capnometry-type oxygen cannula improved the prediction of the absolute value of PaCO2 in extubated post-abdominal surgical subjects without respiratory dysfunction.

Nasal defect repair has been one of the more challenging areas of reconstructive surgery due to the lack of uniform nasal skin thickness and complex contours. Currently, algorithms for medium to large nasal soft tissue defects have been well defined by various authors. Small defects, arbitrarily defined as 1 cm or less, still present significant challenges. In this article, the authors examine the options available to repair small soft tissue nasal defects and the appropriate situations in which each method is best suited. PMID:24872751

Patients suffering from nasal obstruction due to external nasal valve dysfunction may benefit from either corrective surgery or a conservative approach with a nasal dilator. At present, devices for widening the external nasal valve region can be applied externally or endonasally. It remains unknown to what extent the en dona sal dilator Airmax® objectively improves the nasal flow and can be offered as an alternative for surgery. Thirty patients suffering from nasal obstruction due to external nasal valve problems were proposed to use the nasal dilator for 4 weeks as an alternative for corrective surgery. The improvement of nasal flow by the dilator was evaluated by measuring the peak nasal inspiratory flow (PNIF). Then, patients were asked for their willingness to continue to use the nasal dilator or to undergo nasal valve surgery. The endonasal dilator improved the mean PNIF from baseline values with a mean increase of 176.1 o/o. After a 4 week trial period, 19 of 30 patients expressed the intention to continue the use of the nasal dilator. Inappropriate size, local irritation and/or aesthetic nasal complaints were mentioned by the other patients as reasons for discontinuation of using the nasal dilator. The endonasal dilator Airmax® represents a powerful device to improve nasal breathing in the target patients and therefore represents a good alternative for corrective surgery.

The purpose of this 2-phase project was to conduct a formative evaluation and to test the preliminary efficacy of a newly developed Web-based Tailored Intervention for Preparation of parents and children undergoing Surgery (WebTIPS). Phase 1 enrolled 13 children 2 to 7 years of age undergoing outpatient elective surgery and their parents for formative evaluation of WebTIPS. Parent participation focus groups are common in qualitative research and are a method of asking research participants about their perceptions and attitudes regarding a product or concept. In phase 2, children 2 to 7 years of age in 2 medical centers were assigned randomly to receive the WebTIPS program (n = 38) compared with children receiving the standard of care (n = 44). The primary outcome of phase II was child and parent preoperative anxiety. In phase 2, parents reported WebTIPS to be both helpful (P < 0.001) and easy to use (P < 0.001). In phase 2, children in the WebTIPS group (36.2 ± 14.1) were less anxious than children in the standard of care group (46.0 ± 19.0) at entrance to the operating room (P = 0.02; Cohen d = 0.59) and introduction of the anesthesia mask (43.5 ± 21.7 vs 57.0 ± 21.2, respectively, P = 0.01; Cohen d = 0.63). Parents in the WebTIPS group (32.1 ± 7.4) also experienced less anxiety compared with parents in the control group (36.8 ± 7.1) in the preoperative holding area (P = 0.004; Cohen d = 0.65). WebTIPS was well received by parents and children and led to reductions in preoperative anxiety.

The aim of this study was to perform a systematic review of the treatment of nasal bone fractures. The search terms ("nasal bone fracture" AND complication) and ("nasal bone fracture" AND [anosmia OR olfaction OR olfactory nerve OR smell]) and (anosmia AND ["nasal preparation" OR "nasal antiseptics"]) were used to search PubMed and SCOPUS. Of the 500 titles, 40 full papers were reviewed. One paper was excluded, and 3 mined papers were added. Ultimately, 12 papers were analyzed. The overall deformity rate was 10.4% ± 4.8%. No significant differences were found between patients who underwent closed reduction (14.7% ± 7.3%) and those who underwent open reduction (9.4% ± 4.4%), between those who underwent local anesthesia (5.8% ± 4.5%), and those who underwent general anesthesia (8.8% ± 3.8%), or between those who received timely treatment (5.7%) and those whose treatment was delayed (9.0%). Septal deviation occurred in 10.0% of patients as a sequela of nasal bone fracture. The nasal obstruction rate was 10.5% ± 5.3%. Fewer patients of nasal obstruction occurred in the open reduction patients (6.9% ± 4.4%) than in the closed reduction patients (15.2%). One patient of epiphora and 1 patient of diplopia were reportedAmong the 77 patients with nasal bone fractures, 29 (37.7% ± 11.3%) complained of olfactory disturbances. No significant associations were found between the type of fracture and the presence of olfactory disturbances. It is recommended for providers to explain to patients that approximately one-tenth of nasal bone fractures exhibit deformity, septal deviation, or nasal obstruction after surgery. Surgeons should take considerable care to avoid the olfactory mucosa during reduction surgery.

The objectives of this study were to compare history and physical examinations (H&Ps) done by community-based physicians and dentist anesthesiologists for children undergoing general anesthesia for dental rehabilitation. One hundred sixty-eight records were evaluated from the Nationwide Children's Hospital Dental Surgery Center of patients anesthetized between June 2006 and March 2007. These patients had H&Ps completed by both a community-based physician and a dentist anesthesiologist prior to general anesthesia. H&P forms were reviewed by the 3 authors to identify missing data, American Society of Anesthesiologists (ASA) classification, and impact on care. There was a statistically significant difference with respect to 10 of 17 sections examined, with the community-based physicians' H&Ps tending to be incomplete more often. Over 20% of community-based physicians made no mention of the history of present illness. One third of all physician H&Ps were missing vital sign recordings. No significant difference was noted between the physicians' and dentist anesthesiologists' ratings of ASA status. The physician H&P altered course of anesthesia treatment in <1% of studied cases. Statistically significant deficiencies were noted in the physician H&P in 60% of categories. PMID:18547151

Nasal bone fracture is a common injury, but its repair can be unexpectedly difficult. To date, intranasal gauze packing has been used to support the nasal bone in position and to maintain contact between the mucosa of the septum and the cartilage. This gauze packing, however, has a tendency to shift, resulting in an inflammatory response characterized by a foul odor until removal, which detracts from the comfort of the patient. We developed a novel device, the nasal bone clip (NBC), which provides a satisfactory nasal airway and improved comfort. A 1.2-mm Kirschner wire and a small piece of hydrocolloid wound dressing are used. The single wire is bent into a double-curved shape, after which each of the 2 tips is curled with pliers. The end of the wire in the nasal passage is covered with a piece of wound dressing to protect the mucosa. After reduction, the external portion of the wire is inserted on the surface of the splint. The NBC was applied in 14 cases: 12 instances of fresh fractures and 2 of old fractures; there were 8 men and 6 women; their mean age was 19.9 years. Complications were not observed; moreover, no patients exhibited problems during the treatment. The advantages of the NBC are that all materials are available in the operating room or outpatient department, it is low cost, it is readily installable and detachable, it affords superior support for gauze packing, it provides effective external splinting with intranasal support, it never disturbs the nasal airway, and it offers comfort.

Septal suturing following nasal septoplasty, a valid alternative for nasal packing? After septal surgery most surgeons still routinely perform nasal packing since this is generally recommended. The aims of packing are numerous: haemostasis, prevention of haematoma, increase septal flap apposition, closure of dead space and prevention of displacement of the replaced cartilage. However, nasal packing is not an innocuous procedure and may lead to cardiovascular changes, continued bleeding, nasal injury, hypoxia, foreign body reaction or infection. The major disadvantage of nasal packing is patient discomfort--usually necessitating hospital stay--and the need to administer antibiotics. Therefore alternatives were sought. Sessions, Lee and Vukovic conceived and reported in the eighties forms of continuous septal suturing, but are not widely used. A similar technique of septal suturing after nasal septoplasty without nasal packing was used in 226 consecutive surgical procedures and reviewed retrospectively. Complications like postoperative episodes of bleeding, infections, septal haematomas, septal perforations or synechia were not noted. On one patient a recurrence of the septal deviation occurred. Patients reported almost no discomfort. Moreover, the septal surgery procedure could be carried out on a day-surgery basis. Readmission of a patient was never necessary. Based on these observations the septal suturing technique is a valid alternative to intranasal packing following septal surgery.

To compare 3 combinations of 0.5% levobupivacaine (L) and 1% mepivacaine (M) for popliteal block for hallux valgus surgery. Prospective, double blind study of 120 patients undergoing unilateral hallux valgus outpatient surgery with posterior popliteal block with ultrasound-guided single injection. Patients were randomly allocated into three groups: G1: 20mL L+10mL M; G2: 10mL L+20mL M; and G3: 15mL L+15mL M. Recorded variables were: time of block, onset and reversal times for tibial and peroneal nerves block; postoperative pain until the 7(th) day by means of visual analogue scale (VAS), simple descriptive scale and the quality of nocturnal rest, complications, and patient satisfaction. ANOVA and chi2 were applied in the statistical analysis, with a P<0.05 considered significant. Groups were homogeneous for demographic and surgical characteristics. None of the patients required intraoperative complementary analgesia or anaesthesia. Block onset was significantly longer in G1 than in G2 and G3 (39.4±14.7 versus 32.2±16.5 and 33.2±12minutes). Recovery time from sensory and motor block was significantly longer in G1 than in G2 and G3 (29.5±9.3 versus 22.2±8.2 and 24.8±7.9hours). Postoperative pain level was below VAS 30 (1-100) in the three groups; none of the patients experienced severe pain. Maximum pain level appeared at 24h postoperatively. Patient satisfaction was high and there were no complications. Block onset time and anaesthetic efficacy was adequate in the three groups. The combination of 20mL levobupivacaine 0.5% with 10mL mepivacaine 1% provide a good alternative for a lasting postoperative analgesia.

Venous thromboembolic events have several known major risk factors such as prolonged immobilization or major surgery. Pulmonary embolism has rarely been reported after an outpatient vasectomy was completed. We present the rare case of a healthy 32-year-old Caucasian male with no known risk factors who presented with pleuritic chest pain 26 days after his outpatient vasectomy was performed. Subsequently, he was found to have a pulmonary embolism as per radiological imaging. We explore the association between outpatient vasectomies and venous thromboembolic events. A review of the literature is also included. PMID:26989373

Nasal intermittent positive pressure ventilation is likely to have an increasing role in the management of acute ventilatory failure, weaning, and chronic ventilatory problems. Further improvements in ventilator and mask design will be seen. Appropriate application is likely to reduce both mortality and admissions to intensive care, while domiciliary use can improve life expectancy and/or quality of life in chronic ventilatory disorders. As with any new technique, enthusiasm should not outweigh clear outcome information, and possible new indications should always be subject to careful assessment. Images Figure 2 PMID:9799887

Neurinoma grows in the modulated nerve with Schwann cells, and is observed for all positions of the body. It is comparatively rare for neurinoma to grow in the nasal cavity and paranasal sinuses, however. We report a case of neurinoma of the nasal septum. A 24-year-old man seen for nasal obstruction was found in anterior rhinoscopy to have a tumor of the bilateral nasal cavity. Computed tomography (CT) showed a soft tissue density mass in the anterior part of the nasal cavity. Because we suspected neurinoma from biopsy, we resected the tumor by Denker's operation under general anesthesia. We found that it originated from the nasal septum. Histopathological findings of the tumor indicated an Antoni A type neurinoma. After surgery, cartilago costalis was transplanted the plastic surgery to correct the defect in the nasal septum. The post operative course was good and no signs of recurrence were seen. This is the 19th case found in the literature.

The secondary nasal surgery represents a challenging surgical procedure. The difficulties in fact are several: the surgeon must make an effort to achieve the functional and aesthetic consequences of the previous surgical procedure, has to correct the aesthetic and functional imperfections, and has to work on a fibrotic and altered framework.The goal of the secondary nasal surgery is then to restore the normal nasal proportions correcting any functional inability unresolved by the previous surgery or determined by it.The aim of our study is to present our experience in dorsum reconstruction using Medpor. It became necessary as a result of previous surgery procedures responsible for an important sagittal projection deficiency.In the past the autologous grafts were used to restore the correct anatomical relationships.With the improvement in the surgical procedure, the alloplastic implants become of a wider use. Among these, Medpor represents the first choice because of its own intrinsic characteristics.Between 2004 and 2014, 18 patients underwent nasal dorsum reconstruction procedure using Medpor. Medpor was used to reconstruct the nasal dorsum and to augment the columella, supporting the nasal tip.The 18 patients treated by Medpor reported an aesthetic and functional improvement.Medpor represents a safe method in the secondary rhinoplasty to restore the nose anatomy and functionality and to achieve good aesthetic results.

Deformities of the maxilla may exist on all planes, and we treat these problems by mobilizing and repositioning the maxilla on all planes. Some authors have examined the effects of maxillary movement on the nasal airway. In clinical, practice, active anterior rhinomanometry is the most reliable and frequently used method to assess nasal respiratory function. The purpose of this study was to evaluate changes in nasal airflow and nasal airway resistance after maxillary movement performed by active anterior rhinomanometry. We studied 25 patients (18 female patients and 7 male patients; aged 16-30 years) in this clinical trial. Three days before surgery and 6 months after surgery, after a rest period of 30 minutes, active anterior rhinomanometry with a tube was performed at a fixed transnasal pressure of 150 Pa. The surgical treatment plan included bimaxillary surgery consisting of a 1-piece Le Fort I osteotomy combined with a bilateral sagittal split osteotomy. Mean and median total nasal airflow and nasal resistance rate were calculated before surgery and after surgery and compared by use of SPSS software (version 11.5; SPSS, Chicago, IL) and paired t test. An increase in nasal airflow (P = .009) and a decrease in nasal resistance (P = .022) were observed in the maxillary impaction and advancement group. In the maxillary impaction and setback group, there was a significant difference in nasal resistance changes (P = .027); however, postsurgical nasal airflow compared with presurgical values showed no statistically significant difference (P = .244). Impaction and advancement of the maxilla can improve nasal respiratory function, but maxillary impaction and setback reduce nasal respiratory function. Hence candidates for maxillary impaction and setback must be informed about decreased nasal respiratory function.

The internal nasal branch of the infraorbital nerve (ION) runs down the nose and around the ala to be distributed to the nasal septum and vestibule. The aim of this study was to measure the internal nasal branch around the ala of the nose and discuss its possible relevance in clinical/surgical practice. Twelve sides from seven specimens derived from fresh frozen and embalmed Caucasian cadaveric heads were dissected. The specimens included three males and four females. The ages of the cadavers at death ranged from 65 to 84 years. The diameter of the internal nasal branch, horizontal distance from the lateral contour of the ala (Point A) to the branch (distance H) and vertical distance from the bottom part of the ala (Point B) to the branch (distance V) were recorded. Distance H ranged from -1.6 to 1.5 mm on right sides and -1.0 to 1.5 mm on left sides. The diameter of the nerves at Point A ranged from 1.3 to 1.8 mm on right sides and 1.3 to 1.6 mm on left sides. Distance V ranged from -1.5 to 1.0 mm on right sides and -2.3 to 1.1 mm on left sides. The diameter of the nerves at Point B ranged from 0.7 to 1.3 mm on right sides and 0.8 to 1.2 mm on left sides. The results of this study are the first to detail the topography of the internal nasal branch of the ION. Clin. Anat. 30:817-820, 2017. © 2017Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

To evaluate the expression and location of epithelial sodium channels (ENaCs) in human nasal polyp and normal nasal mucosa, and to characterize the relevance of ENaCs to the development of NPs. Nasal polyp tissue from 17 patients and nasal mucosa from ten patients were obtained through endoscopic sinus surgery. The mRNA concentrations of ENaC-α, β, and γ were detected by real-time polymerase chain reaction. The expression of ENaC-α was detected using western blot and immunofluorescence techniques. The distribution of ENaC-α in mucosal tissue was observed using a laser scanning confocal microscope. The transcriptional expression of three subunits of ENaC was in the following order: α > β > γ, in both groups. The transcriptional expression of α, β, and γ subunits of ENaC was elevated in nasal polyp compared to nasal mucosa (p < 0.01). ENaC-α expression was higher in nasal polyp than in nasal mucosa (p < 0.05). Immunofluorescent staining indicated that ENaC-α protein was distributed in the epithelial cell apical membrane. The expression of ENaC is upregulated in human nasal polyp, which might in turn facilitate the formation and development of nasal polyp.

The outpatient monitoring of patients sometimes involves emergency situations. In their practice, the nurses who visit the patient's home are confronted with the limits of their intervention. Faced with these delicate situations team coordination is a strength and the reactivity of the caregivers often contributes to a satisfactory outcome for the patient.

The pathogenesis of nasal polyps still is not clear. This disease is believed to be inflammation related. Previous research has indicated that apoptosis in inflammatory cells is an important factor in the resolution of inflammation. Survivin is regarded as a novel member of the group of inhibitors of apoptosis proteins. It is overexpressed in a number of tumor types. The objective of this study was to investigate the expression of the survivin gene in human nasal polyps. We investigated the expression of survivin in nasal polyps of adult patients with chronic rhinosinusitis. Specimens of nasal polyps were harvested during endonasal sinus surgery (n=22), and the normal mucosa surrounding the nasal polyp tissues or inferior turbinate tissues served as control (n=7). Immunohistochemical staining, reverse transcription polymerase chain reaction (RT-PCR), and Western blotting were performed for detecting the expression of survivin in the nasal polyps. This study has clearly shown that immunoreactivity of survivin significantly increased in the nasal polyp compared with nasal mucosa specimens surrounding nasal polyps (p<0.001). The higher expression of survivin Western blotting and RT-PCR also was observed in the nasal polyp but not in normal nasal mucosa. With a markedly increased expression of survivin in nasal polyps at both the mRNA and the protein levels, we believe the elevated expression of survivin might play an important role of development in nasal polyps.

To determine (1) the use of outpatient services for all surgical breast procedures for breast cancer and (2) the influence of payer and state on the use of outpatient services for complete mastectomy in light of state and federal length-of-stay managed care legislation. Healthcare Cost and Utilization Project representing all discharges from hospitals and ambulatory surgery centers for five states (Colorado, Connecticut, Maryland, New Jersey, and New York) and seven years (1990-96). Longitudinal, cross-sectional analyses of all women undergoing inpatient and outpatient complete mastectomy (CMAS), subtotal mastectomy (STMAS), and lumpectomy (LUMP) for cancer were employed. Total age-adjusted rates and percentage of outpatient CMAS, STMAS, and LUMP were compared. Independent influence of state and HMO payer on likelihood of receiving an outpatient CMAS was determined from multivariate models, adjusting for clinical characteristics (age < 50 years, comorbidity, metastases, simple mastectomy, breast reconstruction) and hospital characteristics (teaching, ownership, urban). In 1993, 1 to 2 percent of CMASs were outpatient in all states. By 1996, 8 percent of CMASs were outpatient in Connecticut, 13 percent were outpatient in Maryland, and 22 percent were outpatient in Colorado. In comparison, LUMPs were 78 to 88 percent outpatient, and by 1996, 43 to 72 percent of STMASs were outpatient. In 1996, women were 30 percent more likely to receive an outpatient CMAS in New York, 2.5 times more likely in Connecticut, 4.7 times more likely in Maryland, and 8.6 times more likely in Colorado compared to New Jersey. In addition, women with Medicare, Medicaid, or private commercial insurance were less likely to receive an outpatient CMAS compared to women with an HMO payer. LUMP is an outpatient procedure, and STMAS is becoming primarily outpatient. CMAS, while still primarily inpatient, is increasingly outpatient in some states. Although clinical characteristics remain important

Transnasal ethmoidectomy is a current treatment in selected cases of nasal polyposis, and with its complicated anatomy offers a proper opportunity for microsurgery. Ten years' experience of microsurgical ethmoidectomy in 155 patients with nasal polyposis is reported. The surgical anatomy of the ethmoid sinus is reviewed with attention to the requirements of the microsurgical approach, and the operative procedure is described. The microsurgical approach is discussed both as a part of the treatment of nasal polyposis and as a new development in rhinologic surgery. Advantages of the technique are the objective safety against risks of the ethmoid area and enhanced sense of security for the surgeon.

The aim of the study was to define and solve main problems in nasal defects reconstruction procedures planning. Fifty-two patients with nasal defects treated in Central Research Institute of Dentistry and Maxillofacial Surgery in 2010-2015 were included in the study. In 28 cases the defects were reconstructed by means of paramedial forehead flap. The authors highlight typical procedure pitfalls mainly associated with the planning stage. The study results prove paramedical forehead flap to be the most useful tool for subtotal and total nasal defects reconstruction but meticulous procedure planning is a must for success.

Objectives (1) Develop a method to account for the confounding effect of the nasal cycle when comparing pre- and post-surgery objective measures of nasal patency. (2) Illustrate this method by reporting objective measures derived from computational fluid dynamics (CFD) models spanning the full range of mucosal engorgement associated with the nasal cycle in two subjects. Study Design Retrospective Setting Academic tertiary medical center. Subjects and Methods A cohort of 24 nasal airway obstruction patients was reviewed to select the two patients with the greatest reciprocal change in mucosal engorgement between pre- and post-surgery computed tomography (CT) scans. Three-dimensional anatomic models were created based on the pre- and post-operative CT scans. Nasal cycling models were also created by gradually changing the thickness of the inferior turbinate, middle turbinate, and septal swell body. CFD was used to simulate airflow and to calculate nasal resistance and average heat flux. Results Before accounting for the nasal cycle, Patient A appeared to have a paradoxical worsening nasal obstruction in the right cavity postoperatively. After accounting for the nasal cycle, Patient A had small improvements in objective measures postoperatively. The magnitude of the surgical effect also differed in Patient B after accounting for the nasal cycle. Conclusion By simulating the nasal cycle and comparing models in similar congestive states, surgical changes in nasal patency can be distinguished from physiological changes associated with the nasal cycle. This ability can lead to more precise comparisons of pre and post-surgery objective measures and potentially more accurate virtual surgery planning. PMID:25450411

To select an effective nasal cavity packing hemostasia material in functional endoscopic sinus surgery. The hemostasia effect and nasal cavity response between vaseline gauze strip and Sorbalgon was compared after FESS. There was a good hemostasia result when using Sorbalgon to pack the nasal cavity in FESS. Only gently headache and nasal cavity pain was found after packing. Few bleeding was taken after nasal wadding drawn out, and the nasal mucosa response was gentle. Sorbalgon is a satisfactory nasal packing material in nasal cavity and sinus operation.
The OPERA trial - comparison of early nasal high flow oxygen therapy with standard care for prevention of postoperative hypoxemia after abdominal surgery: study protocol for a multicenter randomized controlled trial.
Futier, Emmanuel; Paugam-Burtz, Catherine; Constantin, Jean-Michel; Pereira, Bruno; Jaber, Samir
Respiratory support following postoperative extubation is of major importance to prevent hypoxemia and subsequent respiratory failure and reintubation. High-flow nasal cannula oxygen (HFNC) delivers a flow-dependent positive airway pressure and improves oxygenation by increasing end-expiratory lung volume. Whether application of HFNC may have therapeutic advantages over conventional oxygen therapy for respiratory support in the early postextubation surgical period remains to be established. The Optiflow for prevention of post-extubation hypoxemia after abdominal surgery (OPERA) trial is an investigator-initiated multicenter randomized controlled two-arm trial with assessor-blinded outcome assessment, randomizing 220 patients with intermediate to high risk of pulmonary complications after abdominal surgery to receive HFNC or conventional oxygen therapy following extubation, stratified by the presence of epidural analgesia and center. The primary outcome measure is the percentage of patients with postoperative hypoxemia one hour after tracheal extubation. Secondary outcome measures are postoperative pulmonary complications, need for noninvasive ventilation and intubation for respiratory failure. The OPERA trial is the first randomized controlled study powered to investigate whether early application of HFNC following extubation after abdominal surgery prevents against postoperative hypoxemia and pulmonary complications.

The nose is the most prominent aesthetic feature of the facial profile. Nasal length, tip rotation, and tip projection are integral aspects in analysis of the nasal profile. In most rhinoplasties the surgeon has the difficult task of increasing or maintaining tip projection of an underprojected or normally projected nasal tip. Less commonly, the rhinoplastic surgeon is presented with an overprojected nasal tip, and efforts are focused on deprojecting the nasal profile. In this article, the authors present a discussion of the overprojected tip, elucidating strategies of analysis, etiologies, and management of the nasal profile and give clinical examples.

Nasal trauma is a common consequence of athletic competition. The nasal bones are the most commonly fractured facial bone and are particularly at risk during sports participation. Acute management of trauma to the nose includes thorough evaluation of all injuries and may require immediate management for repair of facial lacerations, epistaxis control, or septal hematoma drainage. Nasal fractures can often be addressed with closed reduction techniques; however, in the setting of complex nasal trauma, an open approach may be indicated. Using appropriate treatment techniques, posttraumatic nasal sequelae can be minimized; most patients report satisfactory long-term nasal form and function.

Nasal intubation technique was first described in 1902 by Kuhn. The others pioneering the nasal intubation techniques were Macewen, Rosenberg, Meltzer and Auer, and Elsberg. It is the most common method used for giving anesthesia in oral surgeries as it provides a good field for surgeons to operate. The anatomy behind nasal intubation is necessary to know as it gives an idea about the pathway of the endotracheal tube and complications encountered during nasotracheal intubation. Various techniques can be used to intubate the patient by nasal route and all of them have their own associated complications which are discussed in this article. Various complications may arise while doing nasotracheal intubation but a thorough knowledge of the anatomy and physics behind the procedure can help reduce such complications and manage appropriately. It is important for an anesthesiologist to be well versed with the basics of nasotracheal intubation and advances in the techniques. A thorough knowledge of the anatomy and the advent of newer devices have abolished the negative effect of blindness of the procedure. PMID:27994382

Rhinosinusitis is a common condition with adults experiencing 2-5 episodes per year. The European Positional Paper on Rhinosinusitis and Nasal Polyps (EP3OS) published in 2005 and updated in 2007 provided evidence-based guidelines on the management of sinus disease promoting a conservative approach to treatment. This study examines the effect of EP3OS on sinus surgery uptake and acute admissions for sinusitis in England and Wales. A retrospective study using the national electronic health databases of England (Hospital Episodes Statistics, HES online) and Wales (Patient Episodes Database of Wales, PEDW) was undertaken from 2000 to 2010 using the OPCS-4 codes E12-E17 (sinus surgery) and ICD10 code J01 (acute admission for sinusitis). Data were analysed for effect following the introduction of the EP3OS in 2005 using linear regression and Chi squared analysis. 116,370 sinus procedures and 10,916 acute admissions for sinusitis were made during the study period. No significant decrease in sinus surgery procedures occurred following the introduction of the EP3OS as may have been expected (p > 0.05), although subgroup analysis suggested a significant increase in Wales (p < 0.05). In addition, significant increases in acute admissions for sinusitis were observed following the introduction of EP3OS (p < 0.05). However, subgroup analysis suggested this was not the case in Wales (p > 0.05). The EP3OS appears to have had little impact on the rates of sinus surgery but more conservative approaches to managing of sinus disease may have led to an increase in acute admissions. Further research is required to investigate whether changes in practice were adopted.

Nasal septal hematoma is a rare but potentially serious complication of nasal trauma. Proper management consists of early recognition, prompt surgical evacuation of the hematoma, and antimicrobial therapy if a secondary nasal septal abscess is suspected. Clindamycin is recommended as initial therapy until the results of cultures and susceptibility studies are available.

Chronic nasal disease is often a challenge to diagnose. Computed tomography greatly enhances the ability to diagnose chronic nasal disease in dogs and cats. Nasal computed tomography provides detailed information regarding the extent of disease, accurate discrimination of neoplastic versus nonneoplastic diseases, and identification of areas of the nose to examine rhinoscopically and suspicious regions to target for biopsy.

Altered nasality influences speech intelligibility. Automatic speech recognition (ASR) has proved suitable for quantifying speech intelligibility in patients with different degrees of nasal emissions. We investigated the influence of hyponasality on the results of speech recognition before and after nasal surgery using ASR. Speech recordings, nasal peak inspiratory flow and self-perception measurements were carried out in 20 German-speaking patients (8 women, 12 men; aged 38 ± 22 years) who underwent surgery for various nasal and sinus pathologies. The degree of speech intelligibility was quantified as the percentage of correctly recognized words of a standardized word chain by ASR (word recognition rate; WR). WR was measured 1 day before (t1), 1 day after with nasal packings (t2), and 3 months after (t3) surgery; nasal peak flow on t1 and t3. WR was calculated with program for the automatic evaluation of all kinds of speech disorders (PEAKS). WR as a parameter of speech intelligibility was significantly decreased immediately after surgery (t1 vs. t2 p < 0.01) but increased 3 months after surgery (t2 vs. t3 p < 0.01). WR showed no association with age or gender. There was no significant difference between WR at t1 and t3, despite a post-operative increase in nasal peak inspiratory flow measurements. The results show that ASR is capable of quantifying the influence of hyponasality on speech; nasal obstruction leads to significantly reduced WR and nasal peak flow cannot replace evaluation of nasality.

Objectives This study aimed to evaluate the hypothesis that relief of nasal obstruction in subjects with obstructive sleep apnea (OSA) would lead to reduce OSA severity and to discuss the available evidence on the clinical efficacy of nasal surgery as a treatment modality for OSA. Study Design Twenty-five subjects who had reduced patency of nasal cavity and narrowing of retroglossal or retropalatal airways were diagnosed with OSA and underwent nasal surgery, such as septoplasty or turbinoplasty to correct nasal pathologies. The effect of the surgery on nasal patency was quantified by measuring minimal cross-sectional area (MCA) using acoustic rhinometry. The watch-PAT-derived respiratory disturbance index (RDI), apnea and hypopnea index (AHI), lowest oxygen saturation, and valid sleep time were measured before and after nasal surgery. Results The present study shows that the AHI and RDI decreased significantly and the lowest oxygen saturation and valid sleep time rose after nasal surgery in 25 OSA subjects. In addition, a reduction in subjective symptoms was observed in subjects and mean MCA increased after nasal surgery. Fourteen subjects were classified as responders and 11 subjects as non-responders. Responders showed considerable improvement of their subjective symptoms and the AHI and RDI were significantly lower after surgery. We found that the changes between pre- and post-operative AHI and RDI values were minimal in 11 non-responders. However, daytime somnolence and REM sleep time improved after nasal surgery in non-responders. Conclusions Our study provides evidence that the surgical treatment of nasal pathology improves nasal airway patency and reduces OSA severity in 56% subjects. Furthermore, correction of nasal pathology appears to result in improved sleep quality in both responder and non-responders OSA subjects. PMID:24896824

Packing of the nasal cavity following routine nasal surgery is a common but controversial practice. We aimed to evaluate nasal packing practices among UK ENT consultants for common nasal operations. A questionnaire was sent to 648 consultant ENT surgeons regarding their packing practice in patients undergoing nasal surgery. Data were collected regarding rhinology subspecialty interest, number of nasal operations performed per year, likelihood of packing for six common nasal procedures, and types of pack used. In all, 282 (43.5%) replies were received. Fifty-four (78.3%) rhinologists claimed to perform >100 nasal operations per year versus 64 (31.8%) non-rhinologists (P < 0.005). For specific operations, there was a universal trend towards less routine packing (>70% frequency) in the rhinologist group (P < 0.005). Surgeons who specified a subspecialty interest in rhinology packed significantly less often than the non-rhinologists for common nasal operations. There was great variation in the type of pack favoured by different surgeons.

A 20-year-old man with nasal obstruction underwent septoplasty due to nasal septal deviation. Nasal packs were inserted at the end of surgery and removed 48 hours after surgery. Twenty-four hours after removal of nasal packs, there was necrosis in both sides of septal mucosa and in bilateral inferior turbinates. Nasal swab culture was performed from both nasal cavities. Enterobacter cloacae was isolated from samples. Two weeks after surgery, nasal septum perforation was unavoidable. To our knowledge, this is the first case in literature describing septal mucosal necrosis caused by this pathogen after septoplasty. Mucosal necrosis and perforation as septoplasty complications should be kept in mind, the result of causes both common and, as in the present case, unusual.

Taking advantage of a natural experimental situation, we compared, retrospectively, functional results after nasalization and ethmoidectomy for diffuse nasal polyposis. Nasalization was a radical ethmoidectomy systematically removing all the bony lamellae and mucosa within the labyrinth, with large antrostomy, sphenoidotomy, frontotomy, and middle turbinectomy (Surgeon 1, 39 consecutive patients operated on between March and September 1991). Ethmoidectomy was a less systematic procedure, that was adapted to the extent of the pathology (Surgeon 2, 37 consecutive patients, operated on between October 1991 and November 1994). In May 1994, a third physician mailed a questionnaire simultaneously to all patients including 10-point visual analog scales 34/39 patients in the nasalization group (age: 28-71 years: 20 asthmatics; follow-up: 32-36 months), and 29/37 patients in the ethmoidectomy group (age: 26-65 years: 9 asthmatics: follow-up: 18-31 months) participated in the study. The overall nasal improvement was 8.8 +/- 0.2 (mean +/- SEM) after nasalization and 5.9 +/- 0.6 after ethmoidectomy (p = 0.0001). Olfaction improvement was similar in both groups 6 months after surgery, remained at the same level 36 months after nasalization (6.9 +/- 0.7), but decreased to 4.2 +/- 1 points 24 months after ethmoidectomy (p = 0.02). Asthma improvement remained significantly better after nasalization (p = 0.05), and the need for systemic steroids was also lower (p = 0.03). Results of this study suggest that when dealing with nasal polyposis, the more radical the surgery, the better the functional results.

Clinical studies were performed to assess the clinical outcome of laser assisted endonasal turbinate surgery in long-term. By means of a pulsed Ho:YAG laser emitting at (lambda) equals 2100nm 57 patients suffering form nasal obstruction due to allergic rhinitis and vasomotoric rhinitis were treated under local anesthesia. Furthermore 50 patients were treated by means of light of a diode laser. The light was fed into a fiber being introduced into a fiber guidance system which serves for suction of smoke and pyrolyse products. The distal part of this system could be bent in the range of -5 degrees up to 45 degrees due to the optical axes of the fiber. The study was conducted by a standardized questionnaire, photo documentation, allergy test, mucocilliar function test, rhinomanometry, radiology and histology. Within 2 weeks after laser treatment a significant improvement of nasal airflow correlating to the extent of the ablated turbinate tissue could be determined. This effect lasted up until 1 year post treatment resulting in an improved quality of life in more than 80 percent of the patients. Side effects like nasal dryness and pain were rare, no immediate complications were observed. The total treatment time took 3-8 minutes/turbinate and nasal packing was not necessary after the laser procedure. In conclusion laser treatment by means of the fiber guidance system can be performed as an outpatient procedure under local anesthesia with excellent ablation of soft tissue in a short treatment time with promising results. It will become a time and cost effective treatment modality in endonasal laser surgery.

Twelve patients with nasal polyposis were examined with magnetic resonance imaging (MRI) prior to surgical ethmoidectomies (20 ethmoidectomies). MRI signal was analyzed in correlation with surgical findings in order to define the semiology of nasal and sinuses polyps. One of the most important point of this semiology is based on the analysis of sequences after administration of gadolinium. MRI seems an interesting method for analysing the extension of nasal polyposis and could be useful for ENT surgeons before an endoscopic nasal surgery.

Successful anesthetic management of children undergoing outpatient surgery requires that the surgeon and anesthesiologist be actively involved in all aspects of management. Guidelines should be established in consultation with the surgeons, nurses, and administrators to ensure proper selection and preoperative preparation of patients. The psychological evaluation and preparation of children, and the use of pharmacologic premedication when indicated, will ensure a pleasant experience for all involved. The anesthesiologist should choose a specific anesthetic agent and a technique that are appropriate for each individual child. Use of "routine" induction techniques is rarely, if ever, appropriate. Early ambulation and discharge are very desirable in outpatients. Long-acting drugs and techniques that are associated with excessive drowsiness or nausea and vomiting should not be utilized. Special attention must be paid to the analgesic requirements of the child. Regional blocks should be used whenever possible to supplement "light" general anesthesia and to limit the need for narcotics during recovery. Specific criteria for discharge ensure the safety and protection of the child and staff.
We treated 102 cases of polyps of the nasal cavity and nasal sinuses with Nd:YAG laser surgery or routine surgical removal between January 1987 and August 1988. During a follow up period of 18 - 36 months, the postoperative recurrent rates were 40.6% (24/54) and 66.6% (32/48), respectively, for the laser surgery group and the routine surgical removal group. Laser therapy of nasal polyps has the advantage of less bleeding, no postoperative packing of the nose needed, and lower postoperative recurrence rates. It seems laser surgery may be better than surgical removal alone in the treatment of nasal polyps.

Heating and humidification of the respiratory air are the main functions of the nasal airways in addition to cleansing and olfaction. Optimal nasal air conditioning is mandatory for an ideal pulmonary gas exchange in order to avoid desiccation and adhesion of the alveolar capillary bed. The complex three-dimensional anatomical structure of the nose makes it impossible to perform detailed in vivo studies on intranasal heating and humidification within the entire nasal airways applying various technical set-ups. The main problem of in vivo temperature and humidity measurements is a poor spatial and time resolution. Therefore, in vivo measurements are feasible only to a restricted extent, solely providing single temperature values as the complete nose is not entirely accessible. Therefore, data on the overall performance of the nose are only based on one single measurement within each nasal segment. In vivo measurements within the entire nose are not feasible. These serious technical issues concerning in vivo measurements led to a large number of numerical simulation projects in the last few years providing novel information about the complex functions of the nasal airways. In general, numerical simulations merely calculate predictions in a computational model, e.g. a realistic nose model, depending on the setting of the boundary conditions. Therefore, numerical simulations achieve only approximations of a possible real situation. The aim of this review is the synopsis of the technical expertise on the field of in vivo nasal air conditioning, the novel information of numerical simulations and the current state of knowledge on the influence of nasal and sinus surgery on nasal air conditioning.

Obtaining remote patient-reported outcomes (PRO) is limited by low patient response rates and resource-intensive collection methods. We hypothesized that an e-mail-delivered Web-based data collection tool would outperform the traditional methods of telephone and standard mail for collecting long-term Boston Carpal Tunnel Questionnaire (BCTQ) scores at a minimum of 1 year following carpal tunnel release (CTR). We conducted a randomized trial of 969 patients who underwent CTR at a tertiary medical center within the past 5 years. Participants were randomized to the PRO collection methods of mail, telephone, and e-mail. The primary outcome was survey response rate at 1 year after surgery. Secondary analyses included data completeness and the effect of time from surgery, mode effects, and patient modality preference. At 1 year from surgery, the response rates were 64% for telephone and 42% for both mail and e-mail. Ninety-nine percent of telephone surveys were complete compared with 88% and 83% for mail and e-mail, respectively. There was no significant difference in the overall response rate at 1 or 5 years after surgery, nor in the BCTQ score between the modalities. A higher response rate and increased survey completeness was achieved by telephone contact methods compared with standard mailings or Web-based methods for PRO collection after CTR 1 to 5 years after surgery. A Web-based method demonstrated response rates equivalent to those of standard mail, was the most preferred modality, and offered logistical advantages such as automation and immediate integration with outcome databases. Obtaining PRO routinely after treatment may increase in importance. A Web-based interface may assist clinicians in decreasing the resource utilization typically associated with more traditional methods used to obtain outcome data.

A total of 100 outpatients in the North-East of Scotland were given a simple anaesthetic of propanidid, nitrous oxide, oxygen, and halothane. The study was undertaken to assess what happened to patients when they left hospital after outpatient surgery. An outpatient questionnaire was used, and results show that 31% of patients journeyed home unaccompanied by a responsible person, 73% of car owners drove within 24 hours of the operation, and 9% drove themselves home. Postoperative symptoms of drowsiness (26%), headache (27%), nausea (22%), and dizziness (11%) were recorded, and a higher incidence of symptoms was recorded when surgery exceeded 15 minutes. A new form for outpatient operative procedures in Aberdeen has been devised with modern legal implications in mind. PMID:4643394

The risk of complications warrants treatment of most dislocated nasal fractures. Other injuries including other facial fractures and septal haematoma must be treated if present at the initial presentation. The usual treatment for a simple nasal fracture is closed reduction in local anaesthesia after five to seven days. Complicated cases require open reduction in general anaesthesia. Later revision of the deviated nose may become necessary in patients suffering from complications such as persistent nasal stenosis and/or deformity.

OBJECTIVE: To determine (1) the use of outpatient services for all surgical breast procedures for breast cancer and (2) the influence of payer and state on the use of outpatient services for complete mastectomy in light of state and federal length-of-stay managed care legislation. DATA SOURCES: Healthcare Cost and Utilization Project representing all discharges from hospitals and ambulatory surgery centers for five states (Colorado, Connecticut, Maryland, New Jersey, and New York) and seven years (1990-96). STUDY DESIGN: Longitudinal, cross-sectional analyses of all women undergoing inpatient and outpatient complete mastectomy (CMAS), subtotal mastectomy (STMAS), and lumpectomy (LUMP) for cancer were employed. Total age-adjusted rates and percentage of outpatient CMAS, STMAS, and LUMP were compared. Independent influence of state and HMO payer on likelihood of receiving an outpatient CMAS was determined from multivariate models, adjusting for clinical characteristics (age < 50 years, comorbidity, metastases, simple mastectomy, breast reconstruction) and hospital characteristics (teaching, ownership, urban). PRINCIPAL FINDINGS: In 1993, 1 to 2 percent of CMASs were outpatient in all states. By 1996, 8 percent of CMASs were outpatient in Connecticut, 13 percent were outpatient in Maryland, and 22 percent were outpatient in Colorado. In comparison, LUMPs were 78 to 88 percent outpatient, and by 1996, 43 to 72 percent of STMASs were outpatient. In 1996, women were 30 percent more likely to receive an outpatient CMAS in New York, 2.5 times more likely in Connecticut, 4.7 times more likely in Maryland, and 8.6 times more likely in Colorado compared to New Jersey. In addition, women with Medicare, Medicaid, or private commercial insurance were less likely to receive an outpatient CMAS compared to women with an HMO payer. CONCLUSIONS: LUMP is an outpatient procedure, and STMAS is becoming primarily outpatient. CMAS, while still primarily inpatient, is increasingly

There is no uniform grading system for nasal dorsal deformities currently in general use among surgeons who perform rhinoplasty. Given the popularity of this procedure among both the general public and surgeons, it is time that there was a uniform system describing dorsal deformities. Such a system has value in the education of students of rhinology and cosmetic nasal surgery. We have developed one such system, and applied it to 100 cases. In all cases it accurately describes the major pathological conditions of the dorsum, if present, as noted on physical examination. We have found application of this system to be facile.

Teeth exceeding the normal dental complement that have erupted into the nasal cavity are a rare pathological entity. This case report describes a female patient with recurrent complaints and fetid discharge from the left nasal cavity. The suspected clinical diagnosis of a supernumerary nasal tooth was confirmed by computed tomography. After endoscopic removal, the tooth was examined using X-ray microtomography and thin-section preparations; these findings are presented for the first time. A literature search identified 25 supernumerary nasal teeth in 23 patients.

The nose and the nasal airway is highly complex with intricate 3-dimensional anatomy, with multiple functions in respiration and filtration of the respired air. Nasal airway obstruction (NAO) is a complex problem with no clearly defined "gold-standard" in measurement. There are 3 tools for the measurement of NAO: patient-derived measurements, physician-observed measurements, and objective measurements. We continue to work towards finding a link between subjective and objective nasal obstruction. The field of evaluation and surgical treatment for NAO has grown tremendously in the past 4-5 decades and will continue to grow as we learn more about the pathophysiology and treatment of nasal obstruction.

Nasal problems are a commonly encountered diseases in the ENT (ear, nose, and throat) specialty. People with nasal problems usually seek medical therapy. When the problem cannot resolved by medical therapy then surgery becomes an option. According to statistics of the ENT unit where author served in 2006, 255 patients underwent nasal surgery. Swelling and pain are the most common discomfort symptoms for patients after nasal surgery. After data collection, it was found that only 16.7% of patients were willing to use ice packs, because they attached poorly (100%), were difficult to secure (100%), and were inconvenient to use (83.3%). After seeking an alternative ice pack replacement, the group decided to use a latex glove filled with 50 gm crushed ice and water in its index and middle fingers, tied with shoe laces and tied to the ears. The project involved three periods: preparation, execution, and evaluation. The results showed that 96.7% of patients were willing to use the new ice pack. The satisfaction rate for use of the new ice pack was 96.7%. The results of this project might improve patients' quality of care, as well as cost reduction.

After four nasal aesthetic functional surgeries in a period of 18 months, a 46-year-old woman was evaluated who presented with moderate functional alteration, saddle-nose deformity, and total loss of the septal cartilage. Four months before presentation the patient sustained severe nasal trauma, resulting in depression of the nasal bridge without loss of function. Her problem was diagnosed initially as a consequence of an infected septal hematoma and loss of the septal cartilage. Based on this diagnosis, the patient was subjected, in an 18-month period, to four reconstructive surgeries by different specialists, without any improvement and with worsening of clinical presentation. During the authors' physical examination of the patient, she demonstrated marked nasal cutaneous retraction, atrophic nasal conchae with total loss of the septal cartilage, and a large loss of septal bone. Three nasal mucosa biopsies were acquired and the authors proceeded to carry out complete nasal reconstruction using external cranial table and rib cartilage. Histopathologically, a lesion was noted that was compatible with angiocentric lymphoma, for which treatment was administered according to this type of illness. The authors point out the importance of establishing an adequate diagnosis in the face of an apparently obvious clinical case, present cross-disciplinary treatment, and discuss the study protocol that should be used for this type of pathology. They present their reconstructive technique of the nasal structure using a combination of bone tissue and cartilage, the results, and the current state of the patient.

As the number of ambulatory surgery procedures continues to grow in an aging global society, the implementation of evidence-based perioperative care programs for the elderly patients will assume increased importance. Increasing evidence supports the expanded use of ambulatory surgery for managing elderly patients undergoing elective surgery procedures. This review article describes the demographics of ambulatory surgery in the elderly population. This review article describes the effects of aging on the responses of geriatric patients to anesthetic and analgesic drugs used during ambulatory surgery. Important considerations in the preoperative evaluation of elderly outpatients with co-existing diseases, as well as the advantages and disadvantages of different anesthetic techniques on a procedural-specific basis, and recommendations regarding the management of common postoperative side-effects (including delirium and cognitive dysfunction, fatigue, dizziness, pain, and gastrointestinal dysfunction) after ambulatory surgery. Finally, we discuss the future challenges related to the continued expansion of ambulatory surgery practice in this growing segment of our surgical population. The role of anesthesiologists as perioperative physicians is of critical importance for optimizing surgical outcomes for elderly patients undergoing ambulatory surgery. Providing high-quality, evidence-based anesthetic and analgesic care for elderly patients undergoing elective operations on an ambulatory basis will assume greater importance in the future.

Mucous membrane grafts are used for various indications in oculoplastics. The authors report the use of nasal floor mucosa as a new donor site for mucous membrane grafts. Following adequate anesthesia and vasoconstriction, the nasal floor is visualized with a 30° endoscope. Next, the interior turbinate is medialized, and the nasolacrimal duct is identified and preserved. Anterior, posterior, medial, and lateral incisions are made through the nasal mucosa to the nasal bone. The mucosa is dissected off the nasal bone with a periosteal elevator. Nasal saline irrigation is used postoperatively to aid healing. Histologic analysis of the harvested graft and mucosa from the inferior and middle turbinates were analyzed histologically for the number of mucin-producing cells per high power field and compared. Nasal floor mucosa provides ample tissue for grafting with little donor site morbidity. The surgery is technically easy to learn and perform. There is less risk for blood loss compared with harvesting tissue from the turbinates and less postoperative discomfort compared with buccal mucosal grafts. The grafts have been used in 9 different patients for a variety of ocular indications. Histologically, the nasal floor mucosa contains statistically more mucin-secreting cells than other nasal site, which can be helpful especially in cases of ocular surface disease. In 1 case, biopsy of the grafted tissue at postoperative year 2 showed survival of the respiratory mucin-secreting cells under histologic examination. Nasal floor mucosa should be considered a donor site when a mucous membrane graft is needed. The surgery is safe, easy to perform, and has less morbidity than either a nasal turbinate graft or a buccal mucosal graft.

Ultrasonography has recently been used in assessment and diagnosis of maxillofacial trauma because it is easy and quick to perform, inexpensive, portable, and noninvasive. The aim of this study was to estimate ultrasonography as an intraoperative repositioning control of nasal bone fractures. We studied 32 patients with suspected nasal bone fracture. We performed preoperative computed tomography (CT) for evaluation of the type and extent of nasal bone fractures. We also took external photographs for evaluation of external deviation of the nose and nasal deformity. During surgery, we performed real-time ultrasonography-guided closed reduction using a 10 MHz linear transducer. After 1 year, we performed postoperative evaluation with CT and external photography. We classified patients into three groups according to their CT score. Patients were 23 males and 9 females aged 8-39 years. Clinical symptoms were pain, nasal swelling, nasal bleeding, and localized depression at the trauma site. In almost all patients, postoperative external photographs showed a symmetrical nasal dorsum without external deformity, and postoperative CT showed stabilization of bony fragments and good alignment of the nasal bone. Postoperatively, the CT score was 3 (excellent) in 25 patients, 2 (good) in 5 patients, and 1 (fair) in 2 patients. We suggest that ultrasonography is very useful for evaluating intraoperative repositioning of nasal bone fractures.

Changes of nasal dimensions can influence the air-conditioning capacity of the nose because of alterations of airflow patterns. The goal of this study was to evaluate the correlation between intranasal temperature and humidity values and nasal dimensions, assessed by means of acoustic rhinometry. Eighty healthy volunteers (40 men and 40 women; median age, 51 years; range, 20-84 years) were enrolled in the study. In total, 160 nasal cavities were examined. All volunteers underwent a standardized acoustic rhinometry. Additionally, intranasal air temperature and humidity measurements at defined intranasal detection sites within the anterior nasal segment were performed. There was no statistically significant difference between the right and left side of the nose regarding air temperature, absolute humidity, and acoustic rhinometric values. A negative correlation was established between the rhinometric nasal volumes/minimal cross-sectional areas and air temperature and absolute humidity values at the three intranasal detection sites. According to our results, nasal volumes and cross- sectional areas relevantly influence nasal air conditioning. A healthy nasal cavity with smaller volumes and cross-sectional areas seems to present a more effective air-conditioning function than a too "wide" open nose because of changes in airflow patterns. This observation should be considered as a limitation for overly extensive nasal surgery especially of the turbinates.

Restoring nasal lining is one of the essential parts during reconstruction of full-thickness defects of the nose. Without a sufficient nasal lining the whole reconstruction will fail. Nasal lining has to sufficiently cover the shaping subsurface framework. But in addition, lining must not compromise or even block nasal ventilation. This article demonstrates different possibilities of lining reconstruction. The use of composite grafts for small rim defects is described. The limits and technical components for application of skin grafts are discussed. Then the advantages and limitations of endonasal, perinasal, and hingeover flaps are demonstrated. Strategies to restore lining with one or two forehead flaps are presented. Finally, the possibilities and technical aspects to reconstruct nasal lining with a forearm flap are demonstrated. Technical details are explained by intraoperative pictures. Clinical cases are shown to illustrate the different approaches and should help to understand the process of decision making. It is concluded that although the lining cannot be seen after reconstruction of the cover it remains one of the key components for nasal reconstruction. When dealing with full-thickness nasal defects, there is no way to avoid learning how to restore nasal lining.

This study aimed to compare two sampling methods for nasal nitric oxide in healthy individuals and allergic rhinitis patients, and to examine the within-subject reliability of nasal nitric oxide measurement. The study included 23 allergic rhinitis patients without concomitant asthma and 10 healthy individuals. For all participants, nitric oxide levels were measured non-invasively from the lungs through the mouth (i.e. the oral fractional exhaled nitric oxide) and the nose. Nasal nitric oxide was measured by two different methods: (1) nasal aspiration via one nostril during breath holding and (2) single-breath quiet exhalation against resistance through a tight facemask (i.e. the nasal fractional exhaled nitric oxide). Compared with healthy participants, allergic rhinitis patients had significantly higher average oral and nasal nitric oxide levels. All methods of nitric oxide measurement had excellent reliability. Nasal nitric oxide measurement is a useful and reliable clinical tool for diagnosing allergic rhinitis in patients without asthma in an out-patient setting.

Objective measures can be used to assist the clinician to diagnose and treat nasal obstruction and also to quantify nasal obstruction in research. Objective measurements of nasal obstruction are as important as objective measurements of lung function. peak nasal inspiratory flow (PNIF), acoustic rhinometry (AR) and rhinomanometry (RM), with their specific peculiarity, assess different aspects of nasal obstruction. From the studies available in the literature, it seems that these methods roughly correlate with each other and that all of them can be alternatively utilized very well in research as well as in clinical practice. This review describes the various methods that can be used to measure nasal patency, airflow and resistance, mainly peak nasal inspiratory flow, rhinomanometry and acoustic rhinometry. PNIF has been demonstrated to be reproducible and as good an indication of objective nasal patency as formal rhinomanometry and has the advantage to be cheap, simple and suitable for serial measurements and for home use even in the paediatric population. PNIF normative data are available for children, adults and elderly subjects, and the availability of unilateral PNIF normal values allows evaluation of nasal sides separately. Just as in the lower airways, objective and subjective evaluation gives different information that together optimizes the diagnosis and the treatment of our patients. We argue that PNIF should be used regularly in every outpatient clinic that treats patients with nasal obstruction. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Background With the movement towards bundled payments, stakeholders should know the true cost of the care they deliver. Time-driven activity-based costing (TDABC) can be used to estimate costs for each episode of care. In this analysis, TDABC is used to both estimate the costs of anesthesia care and identify the primary drivers of those costs of 11 common oncologic outpatient surgical procedures. Methods Personnel cost were calculated by determining the hourly cost of each provider and the associated process time of the 11 surgical procedures. Using the anesthesia record, drugs, supplies and equipment costs were identified and calculated. The current staffing model was used to determine baseline personnel costs for each procedure. Using the costs identified through TDABC analysis, the effect of different staffing ratios on anesthesia costs could be predicted. Results Costs for each of the procedures were determined. Process time and costs are linearly related. Personnel represented 79% of overall cost while drugs, supplies and equipment represented the remaining 21%. Changing staffing ratios shows potential savings between 13-28% across the 11 procedures. Conclusions TDABC can be used to estimate the costs of anesthesia care. This costing information is critical to assessing the anesthesiology component in a bundled payment. It can also be used to identify areas of cost savings and model costs of anesthesia care. CRNA to anesthesiologist staffing ratios profoundly influence the cost of care. This methodology could be applied to other medical specialties to help determine costs in the setting of bundled payments. PMID:27637823

This is a method to evaluate both specific sensitivity to allergens in the nasal mucosa, IgE-mediated hypersensitivity, and antiinflammatory and antiallergic drugs efficacy, whose objectives are for research in diagnosis and treatment. The method is based in allergen extracts delivery in the nasal mucosa and the post-challenge measurement of rhinitis symptoms, vasoactive mediators release quantification and nasal obstruction degree evaluated by rhinomanometry. Nasal allergen challenge is a procedure of diagnostic and therapeutic evaluation usefulness, that must be performed in selected patients, in adequate facilities, by experts physicians, with standardised allergen dosages, in an specific nasal area, with objective measurements (rhinomanometry, mediators and secretions of the allergic response) and symptoms scoring that allow get reliable results in patients with allergic rhinitis under study.

The great interest in mucosal vaccine delivery arises from the fact that mucosal surfaces represent the major site of entry for many pathogens. Among other mucosal sites, nasal delivery is especially attractive for immunization, as the nasal epithelium is characterized by relatively high permeability, low enzymatic activity and by the presence of an important number of immunocompetent cells. In addition to these advantageous characteristics, the nasal route could offer simplified and more cost-effective protocols for vaccination with improved patient compliance. The use of nanocarriers provides a suitable way for the nasal delivery of antigenic molecules. Besides improved protection and facilitated transport of the antigen, nanoparticulate delivery systems could also provide more effective antigen recognition by immune cells. These represent key factors in the optimal processing and presentation of the antigen, and therefore in the subsequent development of a suitable immune response. In this sense, the design of optimized vaccine nanocarriers offers a promising way for nasal mucosal vaccination.

Objectives This computational study aims to: (1) Use virtual surgery to theoretically investigate the maximum possible change in nasal aerodynamics after turbinate surgery; (2) Quantify the relative contributions of the middle and inferior turbinates to nasal resistance and air conditioning; (3) Quantify to what extent total turbinectomy impairs the nasal air conditioning capacity. Study Design Virtual surgery and computational fluid dynamics (CFD). Setting Academic tertiary medical center. Subjects and Methods Ten patients with inferior turbinate hypertrophy were studied. Three-dimensional models of their nasal anatomies were built based on pre-surgery computed tomography scans. Virtual surgery was applied to create models representing either total inferior turbinectomy (TIT) or total middle turbinectomy (TMT). Airflow, heat transfer, and humidity transport were simulated at a 15 L/min steady-state inhalation rate. The surface area stimulated by mucosal cooling was defined as the area where heat fluxes exceed 50 W/cm2. Results In both virtual total turbinectomy models, nasal resistance decreased and airflow increased. However, the surface area where heat fluxes exceed 50 W/cm2 either decreased (TIT) or did not change significantly (TMT), suggesting that total turbinectomy may reduce the stimulation of cold receptors by inspired air. Nasal heating and humidification efficiencies decreased significantly after both TIT and TMT. All changes were greater in the TIT models than in the TMT models. Conclusion TIT yields greater increases in nasal airflow, but also impairs the nasal air conditioning capacity to a greater extent than TMT. Radical resection of the turbinates may decrease the surface area stimulated by mucosal cooling. PMID:27165673

The aim of this review was to discuss recent developments in paediatric anaesthesia, which are particularly relevant to the practitioner involved in paediatric outpatient anaesthesia. The use of a pharmacological premedication is still a matter of debate. Several publications are focussing on nasal dexmedetomidine; however, its exact place has not yet been defined. Both inhalational and intravenous anaesthesia techniques still have their advocates; for diagnostic imaging, however, propofol is emerging as the agent of choice. The disappearance of codeine has left a breach for an oral opioid and has probably worsened postoperative analgesia following tonsillectomy. In recent years, a large body of evidence for the prevention of postoperative agitation has appeared. Alpha-2-agonists as well as the transition to propofol play an important role. There is now some consensus that for reasons of practicability prophylactic antiemetics should be administered to all and not only to selected high-risk patients. Perfect organization of the whole process is a prerequisite for successful paediatric outpatient anaesthesia. In addition, the skilled practitioner is able to provide a smooth anaesthetic, minimizing complications, and, finally, he has a clear concept for avoiding postoperative pain, agitation and vomiting.

Thyroidectomy is increasingly being performed as an outpatient procedure. In this study, we aim to examine patient characteristics and clinical factors associated with outpatient thyroid surgeries as compared to inpatient procedures. A cross-sectional study for the period of 2007-2010. Inpatients and outpatients were selected from the Nationwide Inpatient Sample and State Ambulatory Surgery and Services Databases, respectively. All patients were adults (≥18 years) who underwent thyroidectomy in the States of Florida and New York. A total of 25,267 outpatients, and 8219 inpatients were included. Outpatients were more likely to be female, White, have private insurance, and have one or no comorbidities (p < 0.001 each). Thyroid surgeries performed for thyroid conditions other than malignancy were more common in the outpatient settings (p < 0.05 each). High-volume surgeons were more likely to perform ambulatory thyroidectomy (p < 0.001). Post-outpatient thyroidectomy complications were higher for lower volume surgeons (p < 0.001). Moreover, hospital charges for outpatient surgeries performed by lower volume surgeons were significantly higher compared to high-volume surgeons (p < 0.001). Racial and economic disparities exist in the utilization of ambulatory thyroidectomy. Experienced surgeons are more likely to provide ambulatory thyroidectomy, and surgeries performed by them are associated with more favorable outcomes and lower hospital charges.

Tip deformities resulting from previous nasal surgery range from mild to profound. For the mild deformity, morbidity is low and successful correction is usually achieved with a modest and targeted surgical adjustment. However, for the profound deformity, overt cosmetic deformities and corresponding functional impairment are the byproducts of severe derangements in skeletal architecture. Hence, for the severely damaged nasal tip, a complex surgical revision in which the decimated nasal tip framework is reconstructed with autologous cartilage grafts is essential. However, rebuilding the decimated nasal tip is a challenging and risky procedure that is best left to the seasoned rhinoplasty specialist. Careful assessment of the previously operated tissues, combined with an accurate cosmetic analysis, must be juxtaposed with the patient's cosmetic desires to derive an individualized and effective treatment plan. Atraumatic soft tissue technique, combined with a strategic yet balanced and judicious application of graft material, often culminate in satisfactory surgical outcomes. Proper assessment, technical skill, and sound clinical judgment are all critical ingredients in successful restoration of the surgically compromise nasal tip.

Numerous studies have reported an association between nasal obstruction and obstructive sleep apnea syndrome (OSAS), but the precise nature of this relationship remains to be clarified. This paper aimed to summarize data and theories on the role of the nose in the pathophysiology of sleep apnea as well as to discuss the benefits of surgical and medical nasal treatments. A number of pathophysiological mechanisms can potentially explain the role of nasal pathology in OSAS. These include the Starling resistor model, the unstable oral airway, the nasal ventilatory reflex, and the role of nitric oxide (NO). Pharmacological treatment presents some beneficial effects on the frequency of respiratory events and sleep architecture. Nonetheless, objective data assessing snoring and daytime sleepiness are still necessary. Nasal surgery can improve the quality of life and snoring in a select group of patients with mild OSAS and septal deviation but is not an effective treatment for OSA as such. Despite the conflicting results in the literature, it is important that patients who are not perfectly adapted to CPAP are evaluated in detail, in order to identify whether there are obstructive factors that could be surgically corrected.

Closed reduction is generally recommended for acute nasal bone fractures, and rhinoplasty is considered in cases with an unsatisfactory outcome. However, concomitant rhinoplasty with fracture reduction might achieve better surgical outcomes. This study investigated the surgical techniques and outcomes in patients who underwent rhinoplasty and fracture reduction concomitantly, during the acute stage of nasal bone fracture. Forty-five patients who underwent concomitant rhinoplasty and fracture reduction were enrolled. Nasal bone fractures were classified into 3 major types (type I, simple fracture; type II, fracture line that mimics nasal osteotomy; and type III, comminuted fracture) based on computed tomography images and preoperative facial images. Two independent otolaryngology-head and neck surgeons evaluated the surgical outcomes and telephone based survey were made to evaluate patients satisfaction. Among 45 patients, there were 39 males and 6 females. Type I was the commonest type of fracture with 18 patients (40%), while the most frequently used surgical technique for corrective surgery was dorsal augmentation with 44 patients (97.8%). The mean visual analogue scale satisfaction score of the surgeons and patients were 7.62 and 8, respectively, with no significant differences between fracture types. Concomitant rhinoplasty with fracture reduction can be performed for acute nasal bone fracture patients, and it might lead to better aesthetic outcomes.

Setup computational fluid dynamics (CFD) model of the nasal cavity in patients with Crouzon syndrome analyze inspiratory airflow hydrokinetics of its nasal cavity. After changing the morphosis structure of the nasal cavity by operation, compare the preoperative and postoperative alteration of the airflow field of the nasal cavity and evaluate the effect of operation on the physiological function of nasal ventilation. Eleven patients with Crouzon syndrome were underwent spiral computed tomographic laminar scanning to obtain DICOM data and establish the CFD model. The field features of the nasal cavity with inspiratory static state phase were simulated and analyzed by the Fluent software. The changed data on preoperative and postoperative flow field in the nasal cavity in 5 of 11 patients were compared and analyzed. The nasal cavity of a patient with Crouzon syndrome reflected the structural features of relatively short and high-vaulted anteroposterior diameter. The nasal valve was the narrowest region in the nasal cavity and was the key region of producing obvious pressure drop. The inspiratory static state phase reflected comparatively high local airflow rate (approximately 2.469 m/s) and sheer force of the nasal wall. With the distance increasing from the anterior naris, the pressure inside the nasal cavity was decreased gradually. The pressure drop in the nasal cavity before the front end of the concha nasalis inferior (approximately 2 cm from anterior naris) accounted for most of the pressure of the whole nasal cavity (69%-88% of the overall pressure in nasal cavity and 79.24% on average). Osteotomy advancement and distraction osteogenesis increased the anteroposterior diameter of the nasal cavity and the changed nasal resistance. By analyzing the structure of the nasal cavity of patients with Crouzon syndrome and the CFD numerical simulation of patients after the procedure, airflow distribution in patients' nasal cavity and the effect of the surgery on the

Surgical treatment of nasal bone fractures in children is a complex and challenging task not only to maxillofacial surgeons but exceeding to ears, nose, and throat and plastic surgeons. Twelve child patients including 9 boys (75%) and 3 girls (25%) with nasal bone fractures were seen at the Maxillofacial Surgery Department at Ramadi Teaching Hospital during the period of December 2009 to December 2010. Fractured nasal bone is reduced to its anatomic position with Walsham forceps, and the dislocated or disrupted nasal septum with Asch forceps. The most common cause of the injury was road traffic accident and motorcycle accident 5 (42%); nasal deviation was found in 9 cases (75%), and depression in 2 (17%). In 9 patients (75%), injuries were isolated, and 3 (25%) were associated with other facial bone fractures. Significant advances have been made in the management of these injuries, decreasing the incidence of secondary deformities.

With the movement towards bundled payments, stakeholders should know the true cost of the care they deliver. Time-driven activity-based costing (TDABC) can be used to estimate costs for each episode of care. In this analysis, TDABC is used to both estimate the costs of anesthesia care and identify the primary drivers of those costs of 11 common oncologic outpatient surgical procedures. Personnel cost were calculated by determining the hourly cost of each provider and the associated process time of the 11 surgical procedures. Using the anesthesia record, drugs, supplies and equipment costs were identified and calculated. The current staffing model was used to determine baseline personnel costs for each procedure. Using the costs identified through TDABC analysis, the effect of different staffing ratios on anesthesia costs could be predicted. Costs for each of the procedures were determined. Process time and costs are linearly related. Personnel represented 79% of overall cost while drugs, supplies and equipment represented the remaining 21%. Changing staffing ratios shows potential savings between 13% and 28% across the 11 procedures. TDABC can be used to estimate the costs of anesthesia care. This costing information is critical to assessing the anesthesiology component in a bundled payment. It can also be used to identify areas of cost savings and model costs of anesthesia care. CRNA to anesthesiologist staffing ratios profoundly influence the cost of care. This methodology could be applied to other medical specialties to help determine costs in the setting of bundled payments. Copyright © 2015 Elsevier Inc. All rights reserved.

The authors present a case of Pyogenic Granuloma (PG) arising from the nasal septum in the posterior nasal cavity of a patient male sex, caucasian, 32 years old, with a previous history of cranioencephalic trauma, several neurosurgeries for different subsequent neurological problems and the use of a nasogastric tube for feeding (nasal intubation) during 30 days. He underwent surgery in St. Vincent de Paul Hospital (Rio de Janeiro) on May 18, 1993, for the tumor removal and straightening of the nasal septum. Under endoscopic guidance the complete excision of the tumor mass was perfectly done thanks to the excellent exposure of the lesion, provided by the enlarged telescopic view, and the wide access afforded by the septum straighttening plus the cartilaginous septum mobilization through the maxilla-premaxilla approach of Cottle, allied to the lateralization and volume reduction of the right inferior nasal concha, simultaneously performed, thus making lateral rhinotomy or "degloving" unnecessary. The patient is until now (2004) completely free of the lesion operated on. This is the first report in the literature of such a lesion associated to nasal intubation as the triggering agent.

Traditional upper blepharoplasty is a subtractive form of surgery that involves the excision of variable amounts of skin, muscle, and fat from the eyelid. The goal of surgery is to improve field of vision and/or appearance. While surgical debulking of the eyelid may improve appearance early on, the volume loss inherent to this process (especially fat excision) can contribute to a hollowed appearance with an associated deep and sunken superior sulcus. This skeletonized look may be mitigated by repositioning a prominent nasal fat pad, if present, to the central upper eyelid. The charts of patients who underwent upper blepharoplasty with repositioning of the nasal fat pad (as described in this manuscript) to the central arcus marginalis of the superior orbital rim during surgery were reviewed. Patients with a history of previous eyelid surgery or trauma or who had concurrent ptosis or other eyelid malpositions were excluded from the study. Also excluded were patients who did not manifest prominent nasal fat pads at surgery. Postoperative interval follow up was consistent until 6 months after surgery and more sporadic thereafter, as patients more frequently missed appointments. Postoperative healing issues, patient complaints, complications, and subjective physician and patient satisfaction assessments were noted. Final results were gauged on each patient's final visit after surgery. Seventy-six patients were included in the study. Forty-eight patients (63%) were women, and 28 patients (37%) were men. The surgical procedure was uneventful in all patients. The average patient age was 66 years and the mean follow up was 11 months (range 6-22 months). There was one case of postoperative pseudo-Brown syndrome, which resolved with steroid injections. There were 2 cases of postoperative presumed mechanical ptosis, early in the series, lasting for 2 weeks, which in both cases responded to oral steroids. Subjectively, there was no new or worsening superior sulcus hollowness

IMPORTANCE Nasal tip revision remains one of the most challenging surgical procedures for facial plastic surgeons to perform. OBJECTIVE To describe preoperative and postoperative findings related to nasal tip functional and aesthetic aspects following revision rhinoplasty using the "tripod" technique. DESIGN, SETTING, AND PARTICIPANTS A retrospective descriptive study was performed in patients who underwent revision rhinoplasty between 2007 and 2012 at a clinic in Bogota, Colombia. A preoperative diagnosis of nasal tip deformity was made on the basis of photographic records and compared with postoperative nasal tip findings in patients who required the tripod technique. Photographs were evaluated before and after surgery every month for the first 3 months, and after 6, 9, and 12 months postoperatively. MAIN OUTCOMES AND MEASURES Nasal projection, tip rotation, columellar and alar retraction, alar pinch, lack of tip definition, and nasal tip asymmetry. RESULTS Sixty-four of the 69 patients who received revision rhinoplasty using the tripod technique during the study period were enrolled in the study. The tripod technique improved all of the following aesthetic and functional parameters (all P < .001). Nasal tip definition improved in 43 of 49 patients (88%). After surgery, projection was normal in 28 of 40 patients (70%) who had underprojection and overprojection preoperatively, and rotation improved in 29 of 38 patients (76%) who had overrotation or underrotation preoperatively. Columellar retraction improved after surgery in 18 of 24 patients (75%). The alar region improved in 41 of 52 patients (79%) who had alar retraction and/or pinch preoperatively, and inspiratory collapse improved in 49 of 50 patients (98%). CONCLUSIONS AND RELEVANCE The tripod technique is an efficient surgical alternative for nasal tip reconstruction during revision rhinoplasty. This technique allows the destroyed cartilaginous framework to be recreated and returns original nasal tip

Nasalance represents a measure of the relative amount of oral and nasal acoustic energy produced by a speaker. Literature shows changes in nasalance after surgery of the oropharynx. The aim of this prospective study was to evaluate the outcome of speech and nasalance scores after Le-Fort-I-Osteotomy. A total of 20 individuals with normal speech development were examined preoperatively and 6 weeks postoperatively with the Nasometer 6200 (Kay-Elemetrics, USA) after bimaxillary surgery. The tone materials used comprised the standardized text passage: "Ein Kindergeburtstag", the vowels: /a/, /e/, /i/, /o/, /u/ and a syllable repetition subtest. All patients showed changes in nasalance scores 6 weeks postoperatively. There were no significant changes reading the standard text. The syllable repetition test showed significant changes for repetition of "ma ma ma" and "na na na" (p=0,003, respectively p=0,033). Intonation of the vowel /a/1 also revealed significant changes regarding the pre- and postoperative values (p=0,006). However, the obtained values had no significant impact on the nasality characteristics of speech. This study confirms that maxillary osteotomies can result in significant changes of nasalance scores. However these changes do not have any impact on normal speech and voice.

Each of the three types of ethmoidectomy: intra-nasal, trans-antral and external, has its supporters and detractors who argue about the efficacy and safety of the procedures. One hundred and five ethmoidectomies for nasal polyps are reviewed retrospectively. Regardless of the approach used, approximately half of these had recurrence of polyps and some patients had several revision operations. There were six complications specific to the surgery. None was serious but most occurred with external ethmoidectomy. The limitations of ethmoidectomy for nasal polyps, the reasons for the good safety record and the best means of training juniors in the procedures are discussed.

Objectives (1) Analyze the relationship between intranasal airflow distribution and subjective nasal patency in healthy and nasal airway obstruction (NAO) cohorts using computational fluid dynamics (CFD). (2) Determine whether intranasal airflow distribution is an important objective measure of airflow sensation that should be considered in future NAO virtual surgery planning. Study Design Cross-sectional. Setting Academic tertiary medical center and academic dental clinic. Subjects and Methods Three-dimensional models of nasal anatomy were created based on computed tomography scans of 15 patients with NAO and 15 healthy subjects and used to run CFD simulations of nasal airflow and mucosal cooling. Subjective nasal patency was quantified with a visual analog scale (VAS) and the Nasal Obstruction Symptom Evaluation (NOSE). Regional distribution of nasal airflow (inferior, middle, and superior) was quantified in coronal cross sections in the narrowest nasal cavity. The Pearson correlation coefficient was used to quantify the correlation between subjective scores and regional airflows. Results Healthy subjects had significantly higher middle airflow than patients with NAO. Subjective nasal patency had no correlation with inferior and superior airflows but a high correlation with middle airflow (| r| = 0.64 and | r| = 0.76 for VAS and NOSE, respectively). Anterior septal deviations tended to shift airflow inferiorly, reducing middle airflow and reducing mucosal cooling in some patients with NAO. Conclusion Reduced middle airflow correlates with the sensation of nasal obstruction, possibly due to a reduction in mucosal cooling in this region. Further research is needed to elucidate the role of intranasal airflow distribution in the sensation of nasal airflow.

Nasal tip mechanical stability is important for functional and cosmetic nasal airway surgery. Palpation of the nasal tip provides information on tip strength to the surgeon, though it is a purely subjective assessment. Providing a means to simulate nasal tip deformation with a validated model can offer a more objective approach in understanding the mechanics and nuances of the nasal tip support and eventual nasal mechanics as a whole. Herein we present validation of a finite element (FE) model of the nose using physical measurements recorded using an ABS plastic-silicone nasal phantom. Three-dimensional photogrammetry was used to capture the geometry of the phantom at rest and while under steady state load. The silicone used to make the phantom was mechanically tested and characterized using a linear elastic constitutive model. Surface point clouds of the silicone and FE model were compared for both the loaded and unloaded state. The average Hausdorff distance between actual measurements and FE simulations across the nose were 0.39 ± 1.04 mm and deviated up to 2 mm at the outermost boundaries of the model. FE simulation and measurements were in near complete agreement in the immediate vicinity of the nasal tip with millimeter accuracy. We have demonstrated validation of a two-component nasal FE model, which could be used to model more complex modes of deformation where direct measurement may be challenging. This is the first step in developing a nasal model to simulate nasal mechanics and ultimately the interaction between geometry and airflow.

If the septal component of a nasal injury is adequately managed, usually the entire nasal injury will be well managed. Major or minor nasal trauma can cause cartilage fracture, deviation, dislocation, hematoma, or abscess formation, and the various associated sequelae, some of them life-threatening. A negative x-ray report should never be used as a substitute for a complete intranasal examination in any child with nasal trauma. Any nasal abnormality should be referred for immediate evaluation and treatment.

The literature surrounding pediatric burns has focused on inpatient management. The goal of this study is to characterize the population of burned children treated as outpatients and assess outcomes validating this method of burn care. A retrospective review of 953 patients treated the burn clinic and burn unit of a tertiary care center. Patient age, burn etiology, burn characteristics, burn mechanism, and referral pattern were recorded. The type of wound care and incidence of outcomes including subsequent hospital admission, infection, scarring, and surgery served as the primary outcome data. Eight hundred and thirty children were treated as outpatients with a mean time of 1.8 days for the evaluation of burn injury in our clinic. Scalds accounted for 53% of the burn mechanism, with burns to the hand/wrist being the most frequent area involved. The mean percentage of TBSA was 1.4% for the outpatient cohort and 8% for the inpatient cohort. Burns in the outpatient cohort healed with a mean time of 13.4 days. In the outpatient cohort, nine (1%) patients had subsequent admissions and three (0.4%) patients had concern for infection. Eight patients from the outpatient cohort were treated with excision and grafting. The vast majority of pediatric burns are small, although they may often involve more critical areas such as the face and hand. Outpatient wound care is an effective treatment strategy which results in low rates of complications and should become the standard of care for children with appropriate burn size and home support.

"As the septum goes, so goes the nose". A well-known phrase by Maurice Cottle forms the pillar of septoplasty. Since the inception of septal surgeries, numerous methods of septoplasty have been described. But, if not performed meticulously, may lead to deformity. For a successful surgery, understanding the anatomy and addressing the anterior nasal spine and maintaining the tip integrity is vital. To study the outcomes of "ROUND ABOUT technique" to correct deviated nasal septum which focuses on the importance of anterior spine and hence maintain the tip integrity. This was a prospective, single-centre outcome study of 35 patients with symptomatic nasal obstruction. Here, we describe a method of elevating the mucoperichondrial and mucoperiosteal flaps bilaterally, without transecting the quadrilateral cartilage of the septum. The Sino Nasal Outcome Test-22 (SNOT-22) Questionnaire was administered pre-operatively and after 3 months following surgery. The post-operative follow-up period ranged from 3 to 6 months (mean= 4.5 months) to evaluate the functional and aesthetic outcomes of the performed procedure. A total of 35 patients underwent surgery by this technique who presented with deviated nasal septum and variable degrees of nasal obstruction. To assess the statistical outcome, Paired t-test was applied. Mean SNOT-22 scores decreased significantly from 40.02 pre-operatively to 18.65 three months after surgery. The results sustained after 6 months (p-value <0.0001), 85% of these patients had improved breathing post-operatively and none of the patients complained any aesthetic criticisms. The patients were content and the requirement of medications post-operatively were minimal. The ROUND ABOUT technique is a very effective and safe method in correcting the septal deviations especially the ones with caudal or dorsal deflections. It also helps in maintaining the tip integrity and addressing the anterior nasal spine. It avoids the complications of conventional

Unilateral sinus disease (USD) can sometimes be difficult to accurately diagnose before surgery. The application of nasal nitric oxide (nNO) for USD diagnosis and its surgical outcome in USD has not been reported in the literature. We prospectively enrolled sixty-six USD patients who underwent endoscopic sinus surgery for fungal rhinosinusitis (n = 19), chronic rhinosinusitis (CRS) without nasal polyps (n = 13), CRS with nasal polyps (n = 12) and sinonasal mass lesions (n = 22). nNO levels were measured preoperatively and at three and six months postoperatively. Correlations between nNO levels and potential clinical parameters, type of disease, disease severity, and disease-related quality of life (QOL) were assessed. Unlike bilateral CRS, in USD, nNO levels did not correlate with disease severity or postoperative QOL improvements. Except for fungus group, there were no differences in nNO levels between lesion and non-lesion sides in all the other groups. nNO levels on both sides were significantly elevated six months postoperatively in all groups. Fungal rhinosinusitis patients had the lowest preoperative nNO levels, and a cutoff of 239.3 ppb had the best sensitivity (79.0%) and specificity (87.2%) for preoperative diagnosis. While preoperative nNO levels cannot serve as an alternative marker for disease severity of USD, they were lower in fungal rhinosinusitis patients than in other USD patients and may be useful for more accurate diagnosis prior to surgery.

Nasal congestion is a common symptom in rhinitis (both allergic and nonallergic), rhinosinusitis and nasal polyposis. Congestion can also be caused by physical obstruction of nasal passages and/or modulation of sensory perception. Mucosal inflammation underlies many of the specific and interrelated factors that contribute to nasal congestion, as well as other symptoms of both allergic rhinitis and rhinosinusitis. A wide range of biologically active agents (eg, histamine, tumor necrosis factor-α, interleukins, cell adhesion molecules) and cell types contribute to inflammation, which can manifest as venous engorgement, increased nasal secretions and tissue swelling/edema, ultimately leading to impaired airflow and the sensation of nasal congestion. Inflammation-induced changes in the properties of sensory afferents (eg, expression of peptides and receptors) that innervate the nose can also contribute to altered sensory perception, which may result in a subjective feeling of congestion. Increased understanding of the mechanisms underlying inflammation can facilitate improved treatment selection and the development of new therapies for congestion. PMID:20463823

The objective of this study was to describe outcomes for patients who underwent titanium mesh reconstruction of full-thickness nasal defects without internal lining repair. This is a retrospective cohort study. Patients with through-and-through nasal defects were identified at a single academic institution between 2008 and 2016. Nasal reconstruction was performed with either titanium mesh and external skin reconstruction without repair of the intranasal lining or traditional three-layer closure. Five patients underwent titanium mesh reconstruction and 11 underwent traditional three-layer repair. Median follow-up was 11 months (range, 2-66 months). The only significant difference between groups was older age in patients undergoing titanium reconstruction (mean, 81 vs. 63 years; difference of 18; 95% confidence interval [CI], 4-32 years). Defect extent including overall size and structures removed was similar between groups (p > 0.05). Paramedian forehead flap was the most common external reconstruction in both groups (100% for titanium mesh and 73% for three-layer closure). Time under anesthesia was significantly shorter for titanium mesh reconstruction (median, 119 vs. 314 minutes; difference of 195; 95% CI, 45-237). Estimated blood loss and length of hospital stay were similar between groups (p > 0.05). Complication rates were substantial although not significantly different, 40 and 36% in titanium and three-layer reconstruction, respectively (p > 0.05). All patients with complications after titanium reconstruction had prior or postoperative radiotherapy. Titanium mesh reconstruction of through-and-through nasal defects can successfully be performed without reconstruction of the intranasal lining, significantly decreasing operative times. This reconstructive technique may not be suitable for patients who undergo radiotherapy.
The shift of surgeries to outpatient settings could be healthy for medical hotels, those amenity-equipped facilities originally developed to ease patients out of costly acute-care beds. Because fewer hospitals have a pressing need to use such alternative lodging, some medical hotels are hoping to hitch their fortunes to the outpatient trade, keeping patients overnight after surgeries that don't require hospital admission.
Efficacy of augmenting a subacromial continuous-infusion pump with a preoperative interscalene block in outpatient arthroscopic shoulder surgery: a prospective, randomized, blinded, and placebo-controlled study.

This study's purpose was to determine the effectiveness of adding a preoperative interscalene brachial plexus block to standard postoperative management, including oral narcotics and a subacromial bupivacaine infusion pump, after arthroscopic shoulder surgery. After performing a prospective power analysis and obtaining institutional board approval, we conducted a randomized placebo-controlled trial of 53 patients separated into a preoperative interscalene brachial plexus group and a control group. Group 1 received an interscalene block with 30 mL of 0.5% ropivacaine. Group 2 received a placebo with 10 mL of saline solution. All patients postoperatively received an arthroscopically placed subacromial infusion pump catheter for 72 hours and oral narcotics. Pain scores on a visual analog scale (VAS) and narcotic pill use were recorded at 6, 12, 20, 32, 40, 52, 60, 72, and 80 hours. Preoperative pain scores between groups were not significant (P > .05). A statistically significant difference was found for decreased pain scores at 6 hours after discharge in patients receiving an interscalene block (P = .001) (VAS of 30.9 in group 1 v 61.8 in group 2). There was also a decrease in the number of narcotic pills taken at the 6-hour time interval (P = .1) (0.6 pills v 1.1 pills). Group 1 had a rebound phenomenon 20 hours after discharge. Pain scores spiked as the effects of the block wore off (P = .08) (net change in VAS score increase, 25.0 v 10.3). No other statistical or clinical differences were observed. The addition of a preoperative interscalene block to a postoperative subacromial infusion pump provided significant improvement of pain control only at 6 hours after discharge. Twelve hours after discharge, this benefit had disappeared. A rebound phenomenon of increased pain at 20 hours was seen after the interscalene block had worn off. After 20 hours, no statistically significant or clinically applicable differences were found. Level I, randomized controlled trial

Chondrosarcoma of the nasal septum is a rare malignancy. When it occurs, early diagnosis is difficult because patients generally present with common, non-specific sinonasal complaints. This is the report of a 62-year-old woman who presented with a 1-month history of nasal obstruction, headache and anosmia. Nasal endoscopy showed a nasal mass obstructing both nasal cavities not separable from the septum. A wedge biopsy of the nasal mass was taken. Histopathology was suggestive of chondrosarcoma. The tumour was removed by an endoscopic approach. The clinical presentation, diagnosis and treatment of this case as well as a review of the literature are discussed. PMID:22669930

We present a case of confusing white foreign body in the nasal cavity detected during Endoscopic Sinus Surgery (ESS) in a 35-yr-old male which turned out to be a malposition of classic laryngeal mask airway (LMA). Although malposition of LMA is a known entity to the anesthesiologist, if ventilation is adequate, back folded LMA in nasal cavity might not be recognized by the surgeon and lead to catastrophic consequences during endoscopic sinus surgery. In principle, misfolding and malpositioning can be reduced by pre usage testing, using appropriate sizes, minimizing cuff volume, and early identification and correction of malposition.

Nasal polyps and hypertrophic lower nasal conchae are common disorders of nasal cavity. The majority of etiopathogenetic theories indicate inflammatory background of polyps and hypertrophic concha. N-acetyl-β-D-hexosaminidase and β-glucuronidase are lysosomal exoglycosidases revealing accelerated activity in inflammatory processes. The aim of the study was to evaluate the catabolism of glycoconjugates in nasal polyps and hypertrophic nasal concha basing on the activity of N-acetyl-β-D-hexosaminidase (HEX) and β-glucuronidase (GLU). Material consisted of nasal polyps taken from 40 patients during polypectomy in patients with chronic rhinosinusitis with nasal polyps (CRSwNP) and hypertrophic lower nasal conchae taken from 20 patients during mucotomy. The activity of HEX, HEX A, HEX B and GLU in supernatant of homogenates of nasal polyps and hypertrophic lower nasal concha tissues has been estimated using colorimetric method. Statistically significant decrease has been observed in concentration of the activity (per 1mg of tissue) of HEX (p<0.05), HEX B (p<0.001) and specific activity (per 1mg of protein) of HEX B (p<0.001) in nasal polyps tissue in comparison to hypertrophic lower nasal conchae tissue. Decrease in the activity and specific activity concentration of the majority of examined lysosomal exoglycosidases (increasing in inflammations) in comparison to hypertrophic lower nasal conchae suggests electrolytes disorders and questions the inflammatory background of nasal polyps.

Intelectin-1 is a new type of Ca(2+)-dependant soluble lectin in humans that has affinity for galactofuranose in carbohydrate chains of bacterial cell walls, indicating that intelectin-1 may play a role in immune defense against bacteria. The purpose of the current study was to determine the expression of intelectin-1 mRNA and protein and to localize intelectin-1 protein in nasal polyps and tissues from control subjects. Normal sphenoid sinus mucosa was obtained from 10 patients undergoing surgery for pituitary tumor. Nasal polyp samples were obtained from 10 patients undergoing endoscopic sinus surgery for chronic polypoid rhinosinusitis. Real-time polymerase chain reaction (PCR) was performed for intelectin-1 mRNA. Immunofluorescent staining was done for localization of intelectin-1 and quantitatively analyzed using computer-based image analysis. Western blot analysis was performed. Real-time PCR and Western blot analysis showed that intelectin-1 expression in nasal polyps was increased compared with normal sinus mucosa. Using immunofluorescent staining, intelectin-1 was strongly stained in epithelium and submucosa of nasal polyps, and faint staining was found in normal sinus mucosa. Intelectin-1 is expressed in human sinus mucosa and is increased in patients with nasal polyps. These results suggest a possible contribution for intelectin-1 in the pathophysiology of nasal polyps.

The effects of Le Fort I osteotomy on the nasal airway are controversial. This study aimed to evaluate nasal airway changes after Le Fort I. 25 patients underwent conventional Le Fort I osteotomy and were separated into three groups depending on the type of surgery they underwent. 11 patients needed maxillary impaction, 9 underwent maxillary advancement, and 5 had both maxillary impaction and advancement. Rhinological examinations, anterior rhinomanometry and acoustic rhinometry were carried out 1 week before surgery and 3 months after that. Wilcoxon and χ(2) tests were used for data analysis. The samples included 19 females and 6 males with a mean age of 22.4 ± 3.32 years. Rhinomanometric assessment showed that total nasal airflow was increased from 406 ± 202 ml/s to 543 ± 268 ml/s in all three groups. Significant decrease in nasal airway resistance was seen in all three groups. Acoustic rhinometry revealed a significant decrease in total nasal volume but an increase in the cross-sectional areas of isthmus nasi (IN) and inferior concha. The rhinomanometric measurements showed improvements in the total nasal airflow after Le Fort I osteotomy with alar base cinch suture in cases where the impaction was not higher than 5.5mm.

Objective Rhinoplasty, a surgical procedure that alters the shape or appearance of the nose while preserving or enhancing the nasal airway, ranks among the most commonly performed cosmetic procedures in the United States, with >200,000 procedures reported in 2014. While it is difficult to calculate the exact economic burden incurred by rhinoplasty patients following surgery with or without complications, the average rhinoplasty procedure typically exceeds $4000. The costs incurred due to complications, infections, or revision surgery may include the cost of long-term antibiotics, hospitalization, or lost revenue from hours/days of missed work. The resultant psychological impact of rhinoplasty can also be significant. Furthermore, the health care burden from psychological pressures of nasal deformities/aesthetic shortcomings, surgical infections, surgical pain, side effects from antibiotics, and nasal packing materials must also be considered for these patients. Prior to this guideline, limited literature existed on standard care considerations for pre- and postsurgical management and for standard surgical practice to ensure optimal outcomes for patients undergoing rhinoplasty. The impetus for this guideline is to utilize current evidence-based medicine practices and data to build unanimity regarding the peri- and postoperative strategies to maximize patient safety and to optimize surgical results for patients. Purpose The primary purpose of this guideline is to provide evidence-based recommendations for clinicians who either perform rhinoplasty or are involved in the care of a rhinoplasty candidate, as well as to optimize patient care, promote effective diagnosis and therapy, and reduce harmful or unnecessary variations in care. The target audience is any clinician or individual, in any setting, involved in the management of these patients. The target patient population is all patients aged ≥15 years. The guideline is intended to focus on knowledge gaps, practice

Angiomatous nasal polyps are a rarely reported subtype of inflammatory sinonasal polyps that are characterized by extensive vascular proliferation and ectasia. Compromise of their vascular supply may occasionally lead to infarction, resulting in clinical, radiological and pathological features that simulate a neoplastic process. In the present paper, the salient characteristics of this unusual entity are described. The clinical, radiological and pathological features of two patients with infarcted angiomatous nasal polyps are presented. Grossly, the polyps had an unusual inhomogenous appearance and texture and were associated with a foul odor. CT findings included bony expansion and destruction. MRI findings included markedly inhomogenous contrast enhancement on T1-weighted images. Histopathologically, both cases showed abundant vascular ectasia, with widespread intraluminal thrombosis and necrosis. Recanalization and reparative changes were also present. Angiomatous nasal polyps are poorly documented in the literature. Although entirely benign, they may simulate neoplastic processes, thus awareness of their existence is of considerable importance.

Septal deviation constitutes an important component of both esthetic deformity and airway compromise in patients with cleft lip and palate (CLP). The posterior parts of the nasal septum presented greater deviation than the anterior parts in patients with complete unilateral CLP. Le Fort I down-fracture provides better access to the nasal septum than intranasal incision during rhinoplasty, especially to the posterior part. This study objectively and subjectively evaluated the nasal function after Le Fort I osteotomy combined with septoplasty in patients with complete unilateral CLP. Twenty-three patients with complete unilateral CLP presenting with nasal obstruction and septum deviation were included (12-combined surgery group; 11-control group). Types of septum deviation in the patients were analyzed. Presurgical and 6-month-postsurgical acoustic rhinometry (AR) was performed for objective assessment; and the nasal obstruction symptom evaluation (NOSE) scale was used for subjective assessment. The authors used SPSS to compare the baseline and follow-up results. Acoustic rhinometry assessment showed improvements in the nasal minimal cross-sectional area (MCA), nasal resistance, and nasal volumes in 12 patients who received combined surgery. For the 2 groups, significant improvements in nasal breathing were documented (by NOSE scores) at 6 months after surgery. Simultaneous management of the maxillary dysplasia (Le Fort I osteotomy) and intranasal pathology (septoplasty) were effective for relief of nasal airway obstruction in patients with complete unilateral CLP. The combination of objective (AR) and subjective (NOSE scale) assessments allowed better evaluation of the nasal function.

To use computational fluid dynamics (CFD) technology to help providers understand (1) how septal perforations may alter nasal physiology and (2) how these alterations are influenced by perforation size and location. Computer simulation study. Facial plastic and reconstructive surgery clinic. With the aid of medical imaging and modeling software, septal perforations of 1 and 2 cm in anterior, posterior, and superior locations were virtually created in a nasal cavity digital model. The CFD techniques were used to analyze airflow, nasal resistance, air conditioning, and wall shear stress. Bilateral nasal resistance was not significantly altered by a septal perforation. Airflow allocation changed, with more air flowing through the lower-resistance nasal cavity. This effect was greater for anterior and posterior perforations than for the superior location. At the perforation sites, there was less localized heat and moisture flux and wall shear stress in superior perforations compared with those in anterior or posterior locations. For anterior perforations, a larger size produced higher wall shear and velocity, whereas in posterior perforations, a smaller size produced higher wall shear and velocity. Septal perforations may alter nasal physiology. In the subject studied, airflow allocation to each side was changed as air was shunted through the perforation to the lower-resistance nasal cavity. Anterior and posterior perforations caused larger effects than those in a superior location. Increasing the size of anterior perforations and decreasing the size of posterior perforations enhanced alterations in wall shear and velocity at the perforation.

The nasal cavity and parasinusal cancer are rare (10% of tumors of the head and neck) and are mainly represented by squamous cell carcinoma of the nasal cavity or the maxillary sinus and adenocarcinoma of the ethmoid sinus (occupational disease, wood dust). The most common clinical sign is nasal obstruction, but tumors can also manifest as rhinorrhea and/or epistaxis (usually unilateral signs). A magnetic resonance imaging of the facial structure is systematic for staging before treatment. The treatment consists of a first surgery if the patient is operable with a resectable tumor. If it is not the case, the treatment consists of radiotherapy (RT) associated with chemotherapy (CT) according to the initial data (T3/T4 or N+). After first surgery, RT is indicated (except T1N0 with complete resection) associated with a CT based on postoperative data (capsular effraction or incomplete resection). Lymph node irradiation is considered case by case, but is indicated in any nodal involvement. RT must be an intensity modulated RT (IMRT), static or dynamic, and must be imagery guided (IGRT). According to ICRU 83, doses to organs at risk and target volumes must be carried. Finally, after a post-treatment baseline imaging between 2 and 4 months, monitoring will be alternated with the ENT surgeon every 2 or 3 months for 2 years, then every 4 to 6 months for 5 years.

To evaluate the effectiveness of topical anaesthesia with cocaine versus lidocaine plus adrenaline for outpatient transcanalicular and endonasal dacryocystorhinostomy (TCLDCR) with diode laser under sedation. A double blind randomised clinical trial was designed using topical anaesthesia for outpatient TCLDCR in the treatment of adult epiphora. A total of 92 patients were enrolled, and randomly allocated to be operated on under sedation and topical anaesthesia with cocaine 4% pledgets versus sedation and topical anaesthesia with lidocaine 2% plus 1/100.000 adrenaline pledgets. Main outcome measures were postoperative comfort, evaluated by a visual analogue scale, presence of secondary effects (blood pressure, heart rate), and resolution of epiphora, evaluated by Munk's scale and endoscopic control. Patients in both groups reported being comfortable during and immediately after TCLDCR. Visualization of the operative field was adequate, and surgery was successfully completed in all cases. Complications were more common in the cocaine group: Sixteen patients from the cocaine group had high blood pressures, versus 2 patients from the lidocaine group (RR=8). Mean blood loss was 6.09 ml in cocaine group, versus 2.05 ml in lidocaine group (RR=6). Both parameters were statistically significant (p=1,1×10(-9)). There were no cases of postoperative epistaxis requiring nasal packing or hospital admission in any group. Success rate was similar in the 2 groups (86.96% group 1 and 89.13% group 2), after 6 months of follow-up. The combination of topical lidocaine and adrenaline is more effective for outpatient transcanalicular and endonasal dacryocystorhinostomy than topical cocaine. Patient comfort was adequate in both groups, but high blood pressure and blood loss more common after cocaine. Copyright © 2012 Sociedad Española de Oftalmología. Published by Elsevier Espana.

Nasal polyposis complicated the course of fibrosis in 157 (26%) of 605 patients. Onset before age 5 years or after age 20 years was rare. Polyposis was the initial symptom of cystic fibrosis in 13 patients. Common symptoms included obstruction to nasal air flow, mouth breathing, epistaxis, and rhinorrhea. Intranasal and oral corticosteroids and antihistamines were ineffective in preventing recurrences but did occasionally afford symptomatic relief of obstruction. Nineteen (31%) of 62 patients who never had surgery had spontaneous and permanent disappearance of polyps. Simple polypectomy was an adequate procedure for patients with substantial nasal symptoms. There were no visual complications. Other surgical complications were rare. Children and adolescents with nasal polyps should have sweat tests by pilocarpine iontophoresis to rule out cystic fibrosis.

Rhinoliths are calcified masses located in the nasal cavity and may cause symptoms such as nasal obstruction, fetid odour and facial pain. They are usually diagnosed incidentally on radiographic examinations or depending on the symptoms. In this paper we report a 27-year-old Caucasian woman with a calcified mass in the right nasal cavity causing nasal obstruction, anosmia and facial pain. The calcified mass was removed by endonasal approach. PMID:25759270

There are few implant materials which have been successfully used for nasal reconstruction. Of these, the medpor implant is the most accepted alloplastic material for reconstruction of the nasal framework. Here, an unusual complication of a medpor implant in nasal reconstruction is presented. A 24-year-old medical student suffering from a saddle nose deformity after a primary rhino plasty was admitted to our department. The medpor nasal implant was used to restore the nasal dorsum. The surgical result was appreciated by the patient. No problem was encountered during two years after surgery. Recently, the patient suffered from an asymmetry of the nasal dorsum. The physical examination revealed a step on the nasal dorsum with caudal mobility of the implant. The nasal implant was suspected to be broken. Multislice CT scan and ultrasonographic imaging of the implant were obtained. The radiologic evaluation of the region confirmed the fracture of the medpor nasal implant. Nasal reconstruction with a medpor implant is a good choice with low complication rates. This is the first case in the literature reporting a broken medpor nasal implant. Moreover, in this study a new method is described for imaging the medpor implant material.

Objective We evaluated postoperative changes in nasal cavity volume and their effects on nasal function and symptoms after endoscopic endonasal transsphenoidal approach for antero-central skull base surgery. Study Design Retrospective chart review at a tertiary referral center. Methods We studied 92 patients who underwent binostril, four-hand, endoscopic endonasal transsphenoidal approach surgery using the bilateral modified nasoseptal rescue flap technique. Pre- and postoperative paranasal computed tomography and the Mimics® program were used to assess nasal cavity volume changes at three sections. We also performed several pre- and postoperative tests, including the Connecticut Chemosensory Clinical Research Center test, Cross-Cultural Smell Identification Test, Nasal Obstruction Symptoms Evaluation, and Sino-Nasal Outcome Test-20. In addition, a visual analog scale was used to record subjective symptoms. We compared these data with the pre- and postoperative nasal cavity volumes. Results Three-dimensional, objective increases in nasal passage volumes were evident between the inferior and middle turbinates (p<0.001) and between the superior turbinate and choana (p = 0.006) postoperatively. However, these did not correlate with subjectively assessed symptoms (NOSE, SNOT-20 and VAS; all nasal cavity areas; p≥0.05) or olfactory dysfunction (CCCRC and CCSIT test; all nasal cavity areas; p≥0.05). Conclusion Skull base tumor surgery via an endoscopic endonasal transsphenoidal approach altered the patients’ nasal anatomy, but the changes in nasal cavity volumes did not affect nasal function or symptoms. These results will help surgeons to appropriately expose the surgical field during an endoscopic endonasal transsphenoidal approach. PMID:27010730

Computational fluid dynamics (CFD) is a mathematical tool to analyse airflow. As currently CFD is not a usual tool for rhinologists, a group of engineers in collaboration with experts in Rhinology have developed a very intuitive CFD software. The program MECOMLAND(®) only required snapshots from the patient's cross-sectional (tomographic) images, being the output those results originated by CFD, such as airflow distributions, velocity profiles, pressure, temperature, or wall shear stress. This is useful complementary information to cover diagnosis, prognosis, or follow-up of nasal pathologies based on quantitative magnitudes linked to airflow. In addition, the user-friendly environment NOSELAND(®) helps the medical assessment significantly in the post-processing phase with dynamic reports using a 3D endoscopic view. Specialists in Rhinology have been asked for a more intuitive, simple, powerful CFD software to offer more quality and precision in their work to evaluate the nasal airflow. We present MECOMLAND(®) and NOSELAND(®) which have all the expected characteristics to fulfil this demand and offer a proper assessment with the maximum of quality plus safety for the patient. These programs represent a non-invasive, low-cost (as the CT scan is already performed in every patient) alternative for the functional study of the difficult rhinologic case. To validate the software, we studied two groups of patients from the Ear Nose Throat clinic, a first group with normal noses and a second group presenting septal deviations. Wall shear stresses are lower in the cases of normal noses in comparison with those for septal deviation. Besides, velocity field distributions, pressure drop between nasopharynx and the ambient, and flow rates in each nostril were different among the nasal cavities in the two groups. These software modules open up a promising future to simulate the nasal airflow behaviour in virtual surgery intervention scenarios under different pressure or

The purpose of this study was to determine the performance of normalized nasal acceleration (NNA) relative to nasalance as estimates of nasalized versus nonnasalized vowel and sentence productions. Participants were 18 healthy speakers of American English. NNA was measured using a custom sensor, and nasalance was measured using the KayPentax Nasometer II. Speech stimuli consisted of CVC syllables with the vowels (//, /æ/, /i/, /u/) and sentences loaded with high front, high back, low front, and low back vowels in both nasal and nonnasal contexts. NNA showed a small but significant effect of the vowel produced during syllable stimuli but no significant effect of vowel loading during sentence stimuli. Nasalance was significantly affected by the vowel being produced during both syllables and sentences with large effect sizes. Both NNA and nasalance were highly sensitive and specific to nasalization. NNA was less affected by vowel than nasalance. Discrimination of nasal versus nonnasal stimuli using NNA and nasalance was comparable, suggesting potential for use of NNA for biofeedback applications. Future work to improve calibration of NNA is needed to lower intersubject variability.

The purposes of this study were to derive nasalance norms for monolingual Greek speakers, to examine nasalance scores as a function of gender and to draw cross-linguistic comparisons based on normative data. Participants read aloud a corpus of linguistic material, consisting of (1) a nasal text, an oral text and a balanced text; (2) a set of nasal sentences and four sets of oral sentences and (3) repetitions of each of 12 syllable types (8 oral and 4 nasal). The last two sets of material corpus were based on an adaptation of the Simplified Nasometric Assessment Procedures Test (SNAP test) test ( MacKay and Kummer, 1994 ) in Greek, called the G-SNAP test. Eighty monolingual healthy young adult speakers of Greek, 40 males (mean age = 21 years) and 40 females (mean age = 20.5 years), with normal hearing and speech characteristics and unremarkable history were included in the study. The Nasometer (model 6200-3) was used to derive nasalance scores. Mean normative nasalance for spoken Greek was 25.50%, based on the G-oronasal text (with 8.6% nasals). Nasalance scores did not differ significantly with respect to gender. Finally, spoken Greek consistently yielded lower nasalance scores than other languages examined in past work. The aforementioned normative data on nasalance of young adult speakers of Greek are valid across gender and have direct clinical utility as they provide valuable reference information for the diagnosis and management of Greek adults with resonance disorders caused by velar dysfunction.

One of the major causes of chronic nasal obstruction is the nasal septum deformation and increase of the lower nasal turbinates. The number of septoplasty--operations ranges from 14% to 44,2% of all ENT-operations. The results of surgery are swelling of the tissues and damaged ciliar epithelium, that leads to the inparament of the mucociliar transport. In the postoperati e period the nasal cavity should be cleaned. Drugs, that are used, should reduce swelling, improve regeneration and should not supress ciliar activity. The results of supervisory, non-interventional study have shown, that application of Nasiс after septoplasty and submucose vasotomy of inferior nasal turbinates increases reparative process and leads to more rapid recovery of respiratory function of nasal cavity.

Malignant tumors in the nasal region may be treated by means of invasive surgical procedures, with large facial losses. Nasal prostheses, retained by osseointegrated facial implants, instead of plastic surgery, will, in most patients, offer good biomechanical and cosmetic results. This clinical report describes the prosthetic rehabilitation of a patient with nasal cancer who had the entire nasal vestibule removed in a single-stage surgical procedure in order to shorten the rehabilitation time. The nasal prosthesis was built on a 3-magnet bar and was made of platinum silicone with intrinsic pigmentation, thereby restoring the patient's appearance and self-esteem. The authors concluded that single-stage implants may reduce the rehabilitation time to as little as 1 month, and the correct use of materials and techniques may significantly improve the nasal prosthesis.

Proteomics-based approach was applied to analyze and compare the difference of proteins among human nasal inverted papilloma (NIP), nasal polyposis and normal nasal mucosa, in order to screen different proteins as marker. The total proteins of NIP, nasal polyposis and normal nasal mucosa were separated by two-dimensional gel electrophoresis (2-DE). Protein image obtained by using the gel of Calibrated GS-800 Densitometer system, and determined different protein spots. Six differential proteins between NIP and nasal polyp tissue were identified, which were galectin-1, Manganese-superoxide dismutase, galectin-7, trichostatin A, prohibitin and transferring. All of them were increased in NIP. Six differential proteins were possibly involved in NIP, which provided a new way for discriminating NIP from nasal polyposis. The data would be good for the establishment of NIP protein 2-DE map.

Abnormalities of the external shape of the nose are often felt as cosmetically disturbing. In many cases an additional hampering of the respiratory function of the nose is seen and causes pathological nasal airflow patterns. For the functional outcome of aesthetic-surgery of the nose, knowledge of nasal flow is essential. In the medical literature there are some discrepancies between the relationship of nasal shape and nasal flow. We investigated typical airflow patterns in different abnormalities of the external nose. We performed fluid dynamic experiments on exact, anatomical nasal models and functional nasal models (so-called modified Mink boxes). We investigated the inspiratory flow pattern in nose-models with typical variations of the shape of the external nose. There were typical airflow patterns for every external nasal abnormalities. The normal nose shows a disturbance of the streamlines over the entire nasal cavum. Under physiological flow velocities we find laminar and turbulent flow. The pathological variations of the nasal shape show mostly different airflow patterns and characteristics. The main reason for that is a deformed or anatomically false configurated inflow area (vestibulum, isthmus and anterior cavum). During rhinoplasty the reconstruction of the nasal inflow area has to be taken into account.

There are many scaffold materials of repairing nasal alar cartilage defects. Auricuiar cartilage was used extensively in terms of its abundant tissues, good elasticity, little donor-site malformation, good plasticity etc. The authors dissected auricular cartilage and nasal alar cartilage, measured cartilage's morphous data and found some similar territories with nasal alar cartilage in the structure of auricular cartilage. An anatomical study was performed using 10 adult cadavers acquired through Plastic Surgery Hospital, Peking Union Medical College, Beijing, China. Seven male and three female cadav-ers were included in the study. Harvest 20 auricular cartilage specimens and 20 nasal alar cartilage specimens. Then, Computed Tomography Scan on the auricular cartilage and nasal alar cartilage were performed. The datas were imported into mimics and three-dimensional reconstructions of the auricular cartilage and nasal alar cartilage were carried on. Parts of the auricular cartilage, such as conchal fossa, tragus, intertragic notch, and cymba of auricular concha, curs of helix and curs of helix, triangular fossa, are ana-tomically similar to nasal alar cartilage. This study reports the anatomy of auricular cartilage and nasal alar cartilage, found some territories in the auricular cartilage, such as conchal fossa, tragus, intertragic notch, and cymba of auricular concha, curs of helix and curs of helix, triangular fossa, are anatomically similar to nasal alar cartilage. This research provides the anatomical basis that auricular cartilage was used to repair the nasal cartilage defect.

This study assesses the efficacy of alar suspension sutures in the management of nasal valve collapse causing nasal obstruction. These sutures are inserted between the vestibular skin and lateral crura and hitched to the periosteum of the medial inferior orbital margin; this is a variation of the alar (change everywhere) suspension suture technique. A retrospective review of patients who underwent alar suspension suture insertion between January 2009 and December 2010 in the management of nasal obstruction was undertaken. Symptoms of nasal obstruction were assessed using the Visual Analogue Scale (VAS) and peak inspiratory flow rate (PIFR). This was measured preprocedure and repeated at 3, 6, and 12 months postoperatively. A total of 35 patients were identified, and 26 were included in the study; 90% of patients were satisfied with the outcome of surgery, supported by improvement in the VAS and PIFR scores. The mean difference in VAS preprocedure and postprocedure was 4.97 (P value = 0.00), and the average improvement in PIFR was 25.5 L/min (P value = 0.00). Our study shows a significant improvement in patient's symptoms following insertion of alar suspension sutures.

Open reduction through an intercartilaginous incision was useful for treating delayed-diagnosed nasal bone fractures because it resulted in a successful outcome with minimal complications. Nasal bone fractures are generally managed with closed reduction, which is usually inadequate and results in airway obstruction with a delayed diagnosis of nasal bone fracture when bone healing and fibrotic adhesions around the bone fragment have progressed. This study investigated the surgical outcome of open reduction through an intercartilaginous incision for delayed-diagnosis nasal bone fractures. The study enrolled 18 patients who underwent open reduction through an intercartilaginous incision to correct delayed-diagnosis nasal bone fractures. Three independent otorhinolaryngologists evaluated the outcomes 4-35 months (average 12.7 months) postoperatively as excellent, fair or poor. The time from injury to surgery was 11-39 days (20-39 days in adults and 11-30 days in children). The 18 cases included 16 primary repairs and two revisions. A Kirschner wire was inserted in six (33.3%) patients who had unstable reduced nasal bones. Postoperatively, l5 (83%) patients had excellent results, two (11%) had fair, and one (6%) had a poor outcome. No patient experienced any complication.

Computer modelling of fluid flows is a mature technology used widely in engineering. The process, known as computational fluid dynamics (CFD), allows accurate prediction of fluid flow and associated phenomena based on the mathematical laws governing fluid behaviour. A fluid may be defined as any substance that can flow and thus both liquids and gases behave as fluids. The mathematical predictions of CFD can therefore be applied to nasal airflow. In current clinical practice, it is only possible to perform a few limited measurements of nasal airflow, and the clinical relevance of these measurements is questionable. Computer models are not limited by the anatomical inaccessibility of the nasal cavities, and a detailed objective characterisation of airflow can therefore be provided in all areas of an individual nose. In addition, the ability to remodel computer simulations offers a potential predictive tool for planning nasal surgery. This article provides an overview of the basic concepts of computational fluid dynamics, and a summary of the current capabilities of this technology in the characterisation of nasal airflow. The objective is to give otorhinolaryngologists a basic understanding of the computer modelling of nasal airflow, and the background information with which to evaluate CFD-based rhinology literature.

In contrast to the multitude of investigations regarding aesthetic changes in nasal surgery, few data are available concerning nasal function. This is especially important for cleft patients with a compromised nasal respiration.In this prospective study, 68 cleft patients, who underwent nasal surgery, were evaluated concerning aesthetic and respiratory outcome. To assess nasal respiration, active anterior rhinomanometry, rhinoresistometry, and acoustic rhinometry were performed preoperatively and 6 months postoperatively (without and with nasal decongestion, according to international standards). For analyzing the changes in aesthetic parameters, photographs from 3 directions, which were taken preoperatively and at least 6 months postoperatively, were compared. Thus, 57 angles and relations of lines were created out of 54 anthropometric points. The Wilcoxon test was used to compare preoperative and postoperative data (P < 0.05). Regarding aesthetic outcome, a significant improvement in many parameters was seen. The noses postoperatively proved to be significantly narrower and more symmetric and showed a better projection.Although analysis of functional respiratory data showed a significant increase in nasal volume, no change in nasal airflow and hydraulic diameter could be found.Whereas aesthetic improvement of the cleft nose is a goal, which can be achieved regularly, nasal respiration still seems to be a challenge in cleft patients. This study highlights the necessity of taking functional data to learn more about the effects of surgery. Objective methods to assess nasal respiratory function are important for planning and performing nasal surgery and are a means of quality control.

Usually, the nasal sequels of unilateral cleft patient are just considered as an esthetic problem to be addressed after the growth spurt of adolescence. This very narrow vision has led the cleft lip and palate treatment to a deadend. Actually, nasal sequels are the worst in terms of consequence on facial growth. 75% of complete unilateral cleft children are more oral than nasal breathers. Today, we know about the bad consequences of oral breathing on facial growth. It is not surprising to observe a high rate of small maxilla with cleft maxilla scars. In the fetus, the unilateral cleft nose deformities are well explained by the rupture of the facial envelope and the ventilatory dynamics of the amniotic fluid. Every step of the primary treatment threatens the nasal air way patency, whether when repairing lip and nose, suturing the hard palate that is the floor of the nose, or closing the alveolar cleft which controls the width of the piriform aperture. The functional and esthetic nasal sequels reflect the initial deformity, but are also the surgeon's skill and protocol choice. Before undertaking treatment, we must analyze the deformity at every level. Usually, the best option is to reopen the cleft completely to perform a combined revision of the lip, nose, and alveolar cleft after an adequate anterior maxillary expansion. If nasal breathing is necessary for an adequate facial growth, 25 years of experience showed us that it was very difficult to erase the cortical imprint of an early oral breathing pattern. So it is essential to establish a normal nasal breathing mode at the initial surgery. When the initial surgery is efficient and/or the secondary repair is successful, the final esthetic rhinoplasty, when indicated, is just performed for the sake of harmonization, with a classic internal approach and a few refinements.

Rhinoplasty often requires the use of grafting material, and the goal of the specific graft dictates the ideal characteristics of the material to be used. An ideal material would be biologically inert, resistant to infection, noncarcinogenic, nondegradable, widely available, cost-effective, readily modifiable, and easily removable, have compatible biomechanical characteristics, retain physical properties over time, and not migrate. Unfortunately, no material currently in existence meets all of these criteria. In modern rhinoplasty, autologous grafts are the gold standard against which all other nasal implants are measured and offer the safest long-term results for most patients. They are easily manipulated, have inherent stability and biomechanical characteristics similar to the native nasal framework, and confer minimal risk of complications. Modern homologous and alloplastic materials have gained considerable support in recent years because they are readily available in endless quantity, do not require a second surgical site for harvest, and are generally considered safe if most circumstances, but they confer additional risk and have biomechanical characteristics different from that of the native nasal framework. To address some of these issues, we provide a contemporary review of autologous, homologous, and alloplastic materials commonly used in rhinoplasty surgery.

To investigate the impact of airflow communication between bilateral nostril sides on nasal ventilation. In addition, we try to validate the efficacy of the Draf III procedure from the aerodynamics perspective. One health model and two disease models were constructed. These included 2 patients with nasal septum perforation and 1 patient who received the Draf III procedure. With the computational fluid dynamics method, indices such as airflow velocity and wall shear stress in the nasal cavity were detected and compared among the 3 subjects. The main pathway for airflow in the nasal cavity is the common meatus. Little airflow exchange occurred in the patient who underwent the Draf III procedure, and the wall shear stress around the communication site was as low as in the adjacent areas. However, when airflow communication occurred in the lower part of the nasal cavity, the airflow velocity and wall shear stress were obviously altered, and the ventilation function of the nasal cavity was impaired. Airflow communication in the upper part of the nasal cavity has little impact on nasal ventilation. Nonetheless, airflow communication occurring in the lower part of the nasal cavity disturbs the overall airflow distribution and a repair procedure is necessary. © 2013 S. Karger AG, Basel.

Health insurance companies commonly require a trial of corticosteroid nasal spray prior to authorizing nasal surgery, even in patients with severe to extreme anatomical nasal obstruction, despite lack of data supporting such medical therapy. To provide a model for the comparative analysis of medical vs surgical treatment for nasal obstruction to help maximize health care benefit per dollar spent and to explore the cost-effectiveness of corticosteroid nasal spray in patients with severe to extreme nasal airway obstruction on Nasal Obstruction Symptom Evaluation (NOSE) scores. A cost-efficiency frontier economic evaluation was performed. The economic perspective was that of the health care third-party payer. Effectiveness data were obtained from NOSE score questionnaires in 179 patients. An incremental cost-effectiveness ratio was determined from the cost and efficacy data. Comparative treatment groups were medical therapy with corticosteroid nasal spray vs surgical therapy for nasal airway obstruction. The study was conducted between January 1, 2011, and December 30, 2013. The time horizon included 1, 2, and 5 years. Data analysis was completed June 1, 2015. The primary outcome was cost per quality-adjusted life-year (QALY). A modified Markov decision tree model was used. Costs were obtained from the Medicare 2015 physician fee schedule, and the mean was determined (owing to geographic disparity) along with wholesale and generic pharmaceutical pricing. Among 100 men and 79 women evaluated (mean [SD] age, 37.9 [12.9] years), surgical repair of severe nasal airway obstruction cost $6537 and produced a total of 1.15 QALYs at 1 year. Medical treatment involved a trial of corticosteroid nasal sprays, which cost $520 and produced a total of 1.03 QALYs. The surgical approach was markedly more effective but at greater short-term cost. In cases of extreme nasal obstruction, medical treatment cost $520.73 with 1.004 QALYs, demonstrating an incremental cost-effectiveness ratio

Respiratory physiology and pathology are strongly dependent on the airflow inside the nasal cavity. However, the nasal anatomy, which is characterized by complex airway channels and significant individual differences, is difficult to analyze. Thus, commonly adopted diagnostic tools have yielded limited success. Nevertheless, with the rapid advances in computer resources, there have been more elaborate attempts to correlate airflow characteristics in human nasal airways with the symptoms and functions of the nose by computational fluid dynamics study. Furthermore, the computed nasal geometry can be virtually modified to reflect predicted results of the proposed surgical technique. In this article, several computational fluid mechanics (CFD) issues on patient-specific three dimensional (3D) modeling of nasal cavity and clinical applications were reviewed in relation to the cases of deviated nasal septum (decision for surgery), turbinectomy, and maxillary sinus ventilation (simulated- and post-surgery). Clinical relevance of fluid mechanical parameters, such as nasal resistance, flow allocation, wall shear stress, heat/humidity/NO gas distributions, to the symptoms and surgical outcome were discussed. Absolute values of such parameters reported by many research groups were different each other due to individual difference of nasal anatomy, the methodology for 3D modeling and numerical grid, laminar/turbulent flow model in CFD code. But, the correlation of these parameters to symptoms and surgery outcome seems to be obvious in each research group with subject-specific models and its variations (virtual- and post-surgery models). For the more reliable, patient-specific, and objective tools for diagnosis and outcomes of nasal surgery by using CFD, the future challenges will be the standardizations on the methodology for creating 3D airway models and the CFD procedures.

Nasal deviation is a common complaint in otorhinolaryngology and plastic surgery. This condition not only causes impairment of nasal function but also affects quality of life, leading to psychological distress. The subjective assessment of quality of life, as an important aspect of outcomes research, has received increasing attention in recent decades. Quality of life is measured using standardized questionnaires that have been tested for reliability, validity, and sensitivity. The aim of this study was to evaluate health-related quality of life, self-esteem, and depression in patients with nasal deviation. Sixty patients were selected for the study. Patients with nasal deviation (n = 32) were assigned to the study group, and patients without nasal deviation (n = 28) were assigned to the control group. The diagnosis of nasal deviation was made by digital photogrammetry. Quality of life was assessed using the Medical Outcomes Study 36-Item Short Form Health Survey questionnaire; the Rosenberg Self-Esteem/Federal University of São Paulo, Escola Paulista de Medicina Scale; and the 20-item Self-Report Questionnaire. There were significant differences between groups in the physical functioning and general health subscales of the Medical Outcomes Study 36-Item Short Form Health Survey (p < 0.05). Depression was detected in 11 patients (34.4 percent) in the study group and in two patients in the control group, with a significant difference between groups (p < 0.05). Nasal deviation is an aspect of rhinoplasty of which the surgeon should be aware so that proper psychological diagnosis can be made and suitable treatment can be planned because psychologically the patients with nasal deviation have significantly worse quality of life and are more prone to depression.

In order to characterize acoustic properties of nasal and nasalized vowels, these sounds will be considered as a dynamic trend from an oral configuration toward an [n]-like configuration. The latter can be viewed as a target for vowel nasalization. This target corresponds to the pharyngonasal tract and it can be modeled, with some simplifications, by a single tract without any parallel paths. Thus the first two resonance frequencies (at about 300 and 1000 Hz) characterize this target well. A series of measurements has been carried out in order to describe the acoustic characteristics of the target. Measured transfer functions confirm the resonator nature of the low-frequency peak. The introduction of such a target allows the conception of the nasal vowels as a trend beginning with a simple configuration, which is terminated in the same manner, so allowing the complex nasal phenomena to be bounded. A complete study of pole-zero evolutions for the nasalization of the 11 French vowels is presented. It allows the proposition of a common strategy for the nasalization of all vowels, so a true nasal vowel can be placed in this nasalization frame. The measured transfer functions for several French nasal vowels are also given.

ABSTRACT Objective: In recent years, various investigators have shown considerable interest in the use of macrolide antibiotics for treatment of chronic rhinosinusitis and nasal polyposis. The aim of this study was to evaluate the clinical effects of preoperative long-term, low-dose clarithromycin administration in patients with nasal polyposis. Methods: Eighty nasal polyp patients (42 non-atopic and 38 atopic) were included in this prospective, non-placebo controlled investigation and randomized equally to either the combined clarithromycin-surgical or surgical group. Forty patients received 500 mg of clarithromycin daily for eight weeks, and, after evaluation, they were treated by functional endoscopic sinus surgery (FESS). The other 40 patients were treated only surgically. The nasal symptom scores and endoscopic scores after macrolide treatment/surgical treatment, and after six and 12 months of follow-up were evaluated. Results: After clarithromycin therapy, we found improvement in symptom scores in 25/40, and improvement in endoscopic scores in 19/40 patients. We found no significant difference in nasal symptom score between allergic and non-allergic patients regarding the outcome to macrolide (p = 0.352) or surgical treatment (p = 0.396). When we compared differences between endoscopic scores at the time points of 12 months and six months postoperatively (ESt12 minus ESt6), we found statistically lower differences in the clarithromycin-surgery group than in the surgery group (p = 0.006). Conclusion: Preoperative clarithromycin administration postponed nasal polyp relapse after FESS. Allergies have no influence on the clinical efficacy of clarithromycin therapy and on the efficacy of FESS. PMID:25867579

Knowledge on the airflow patterns in the nasal cavity is essential to understanding the function of the nasal cavity. This study has attempted to observe the breath cycle of nasal airflow during respiration at rest. We constructed a nasal cavity model by rapid prototyping using 1.25-mm-thick CT data and devised a piston pump driven by a cam, to simulate respiration at rest. The airflow was evaluated with particle image velocimetry and visualized in coronal reconstructed images. During the inspiration, a maximal velocity was observed at the valve area and the main stream occurred in the middle and superior airways. During the expiration, main stream was noted in the middle airway and was slow compared with the flow during inspiration. Vortexes were observed between inspiration and expiration. This result widens our knowledge of nasal airflow and this technique will allow a more physiological understanding of nasal operations.
To determine the frequency of staphylococcal nasal carriage of health care workers (HCWs) and antimicrobial susceptibility profile of the isolates for appropriate decolonization therapy. An observational study. The study was conducted at Holy Family Hospital, Rawalpindi, during the period from May 2007 to April 2008. Nasal swabs from anterior nares of HCWs were cultured and identified as Staphylococcus aureus, coagulasenegative staphylococci (CoNS), methicillin-resistant S. aureus (MRSA), methicillin-resistant CoNS (MRCoNS) by using standard methods. Antimicrobial susceptibility testing was performed on Muller Hinton Agar using disc diffusion method. Of the 468 HCWs, 213 (45.5%) participants were men and 255 (54.5%) were women. Eighty five (18.2%) were nasal carriers of S. aureus, 07 (1.5%) for MRSA, 343 (73.3%) for CoNS and 10 (2.1%) for MRCoNS. The highest carriage rate for S. aureus was in midwives (30%) followed by maintenance staff (28.6%), security guards (25%), technicians (23.5%), staff nurses (22.7%) and < 20% in house physicians and nursing students. Carriage rate in HCWs from different departments was: surgical ICU (40%), gynaecology (34.9%), delivery room (30%), gynaecology operation rooms (25%), medicine (22.7%) and < 20% in pediatrics and surgery. All isolates were susceptible to vancomycin, imipenem and levofloxacin and > 90% of S. aureus and CoNS were susceptible to amikacin, gentamicin and fluoroquinolones tested. Fluoroquinolones, preferably oral levofloxacin in combination with topical gentamicin ointment, in places like Pakistan where mupirocin is not routinely available, can be used for decolonization of nasal staphylococcal carriage.

Nasal obstruction can be monitored objectively by measurement of nasal airflow, as evaluated by nasal peak flow, or as airways resistance/conductance as evaluated by rhinomanometry. Peak flow can be measured during inspiration or expiration. Of these measurements, nasal inspiratory peak flow is the best validated technique for home monitoring in clinical trials. The equipment is portable, relatively inexpensive, and simple to use. One disadvantage, however, is that nasal inspiratory peak flow is influenced by lower airway as well as upper airway function. Rhinomanometry is a more sensitive technique that is specific for nasal measurements. The equipment, however, requires an operator, is more expensive, and is not portable. Thus, it is applicable only for clinic visit measures in clinical trials. Measurements require patient cooperation and coordination, and not all can achieve repeatable results. Thus, this objective measure is best suited to laboratory challenge studies involving smaller numbers of selected volunteers. A nonphysiological measure of nasal patency is acoustic rhinometry. This sonic echo technique measures internal nasal luminal volume and the minimum cross-sectional area. The derivation of these measures from the reflected sound waves requires complex mathematical transformation and makes several theoretical assumptions. Despite this, however, such measures correlate well with the nasal physiological measures, and the nasal volume measures have been shown to relate well to results obtained by imaging techniques such as computed tomography scanning or magnetic resonance imaging. Like rhinomanometry, acoustic rhinometry is not suitable for home monitoring and can be applied only to clinic visit measures or for laboratory nasal challenge monitoring. It has advantages in being easy to use, in requiring little patient cooperation, and in providing repeatable results. In addition to nasal obstruction, allergic rhinitis is recognized to be associated with

Enhancing nasal tip definition requires a three-dimensional approach encompassing both form and function. Dome refinements achieved during surgery should be created with sufficient integrity to withstand postoperative healing forces. Stabilizing the nasal base is the first component of dome alterations and prevents loss of tip rotation and projection. Structural grafting can be used to enhance tip definition and at the same time adds support to the cartilaginous framework. Tip shield grafts camouflage dome asymmetries, establish the tip-defining point, and enhance the supratip break. Shield grafts can be placed in all skin types with appropriate contouring and camouflaging techniques.

Background: Nasal airway obstruction (NAO) is a common health condition impacting mood, energy, recreation, sleep, and overall quality of life. Nasal surgery often addresses NAO but the results are sometimes unsatisfactory. Evaluating surgical treatment efficacy could be improved if objective tests were available that correlated with patient-reported measures of symptoms. The goal of this study was to develop methods for comparing nasal resistance computed by computational fluid dynamics (CFD) models with patient-reported symptoms of NAO using early data from a 4-year prospective study. Methods: Computed tomography (CT) scans and patient-reported scores from the Nasal Obstruction Symptom Evaluation (NOSE) scale and a visual analog scale (VAS) measuring unilateral airflow sensation were obtained pre- and postoperatively in two NAO patients showing no significant mucosal asymmetry who were successfully treated with functional nasal surgery, including septoplasty. Pre- and postsurgery CFD models were created from the CT scans. Numerical simulation of steady-state inspiratory airflow was used to calculate bilateral and unilateral CFD-derived nasal resistance (CFD-NR). Results: In both subjects, NOSE and VAS scores improved after surgery, bilateral CFD-NR decreased, and unilateral CFD-NR decreased on the affected side. In addition, NOSE and VAS scores tracked with unilateral CFD-NR on the affected side. Conclusion: These preliminary results suggest a possible correlation between unilateral NR and patient-reported symptoms and imply that analysis of unilateral obstruction should focus on the affected side. A formal investigation of unilateral CFD-NR and patient-reported symptoms in a series of NAO patients is needed to determine if these variables are correlated. PMID:22643935

Computational fluid dynamics has been adapted to studying nasal aerodynamics. To review current literature on CFD studies, with an emphasis on normal nasal airflow, the impact of sinonasal pathology on airflow, and implications on nasal physiology. The objective is to provide the rhinologists with a greater understanding of nasal airflow and how symptomatology of sinonasal disease may be explained via CFD simulations. The nasal valve region redirects inspiratory airstreams over the inferior turbinate in a high turbulent kinetic energy, which is important in heat and moisture exchange. The bulk of airflow occurs in the common meatus with small streams traversing the olfactory groove, increasing during sniffing. Septal deviation and enlarged inferior turbinate causes redistribution of airflow, changes in intranasal pressure and increased turbulence. High velocity airflow and wall shear stress at the septal perforation causes desiccation and mucosal damage. The airflow within an atrophic nasal cavity is predominantly laminar with minimal contact with nasal mucosa. The inferior turbinate is an important organ for air conditioning and preservation during surgery is highlighted. Despite some limitations of CFD simulations, this technology has improved understanding of the complex nasal anatomy and the implications of disease and surgery on physiology.

Nasal bone fracture is the most common among facial bone fractures. The prevalence of concomitant septal and nasal bone fractures fluctuates between 34% and 96.2%. An adequate management of such fractures is essential to prevent complications such as post-traumatic nasal obstruction and nasoseptal deformities. The purpose of the present study is to introduce the submucosal endoscopically assisted septoplasty (SEAS) as an alternative approach for acute septal lesions and to report our experience and outcomes. Retrospective review including patients with nasal fracture in association with septal fracture (nasoseptal fractures) who underwent to submucosal endoscopically assisted septoplasty and closed nasal reduction. The surgical technique is described and a video is presented. Ninety patients were included; 23% were female and 77% were male, with a mean age of 40 years. All the cases were workplace accidents or commuting accidents. The mean time elapsed between the accident and surgery was 15 days. There were no technique-related intraoperative complications. Three (3.3%) patients suffered a subsequent nasal obstruction and/or deviation of the nasal axis, requiring subsequent secondary open rhinoseptoplasty. Submucosal endoscopically assisted septoplasty and closed nasal reduction for the treatment of nasoseptal fractures is a novel approach that reduces the rate of secondary rhinoseptoplasty as compared to other authors' reports. The technique described is reproducible, cost-effective and has very encouraging outcomes. IV Therapeutic. Copyright © 2016 European Association for Cranio-Maxillo-Facial Surgery.

To assess the differences in nasal anthropometric measurements between Korean American women and North American white women and to perform an in-depth nasal index calculation. This anthropometric survey included a volunteer sample of Korean American women (n = 72) aged 18 to 35 years with Korean parents and no previous nasal surgery or trauma to the nose. Standardized and referenced frontal, lateral, and basal photographs of the nose were taken of the subjects and 22 standard anthropometric measurements of the nose were determined. Results were compared with published standards for North American white women. In addition, 18 nasal indices were calculated and compared with the published standards for North American white women. The Korean American woman's nose did not fit the neoclassic facial canons. Compared with North American white women, 20 of 22 nasal measurements in Korean American women were found to be significantly different. Nasal indices also revealed significant differences in 16 of the 18 that were calculated. The Korean American woman's nose exhibits less rotation, has a flatter dorsum, and is more flared at the alae, with less definition of the nasal tip. The average Korean American and North American white female nasal anthropometric measurements are very different. As cosmetic surgery becomes more popular among Asian Americans, our findings bolster the need for a broader view of facial analysis and transcultural aesthetics.

OBJECTIVE: to assess the incidence and risk factors associated with nasal septum injury in premature infants using reused and new nasal prongs. METHOD: the study was a cohort from an open therapeutic intervention. The sample included 70 infants with a gestational age inferior to 37 weeks, who used nasal prongs and were hospitalized at the neonatal service of a hospital in Recife-PE, in the Northeast of Brazil. The data were collected in patient files through the assessment of the application of the device and of the nasal septum. Multinomial Logistic Regression and Survival analyses were applied. RESULTS: the incidence of nasal injury corresponded to 62.9%. In the multiple analysis, only the length of the infant's treatment was a determinant factor for the occurrence and severity of the injuries. CONCLUSION: the type of nasal prong does not serve as a risk factor for the nasal injury. The high incidence of nasal injury indicates the need to adapt the nursing care with emphasis on prevention.

This article describes the development and initial validation of an objective measure of nasal air emission (NAE) using nasal accelerometry. Nasal acceleration and nasal airflow signals were simultaneously recorded while an expert speech language pathologist modeled NAEs at a variety of severity levels. In addition, microphone and nasal accelerometer signals were collected during the production of /pɑpɑpɑpɑ/ speech utterances by 25 children with and without cleft palate. Fourteen inexperienced raters listened to the microphone signals from the pediatric speakers and rated the samples for the severity of NAE using direct magnitude estimation. Mean listener ratings were compared to a novel quantitative measurement of NAE derived from the nasal acceleration signals. Correlation between the nasal acceleration energy measure and the measured nasal airflow was high (r = .87). Correlation between the measure and auditory-perceptual ratings was moderate (r = .49). The measure presented here is quantitative and noninvasive, and the required hardware is inexpensive ($150). Future studies will include speakers with a wider range of NAE severity and etiology, including cleft palate, hearing impairment, or dysarthria. Further development will also involve validation of the measure against airflow measures across subjects.

Background: Sarcoidosis is a multisystem granulomatous inflammatory disease that is induced by infectious or noninfectious environmental antigens in a genetically susceptible host. Tuberculosis and sarcoidosis are two diseases with similar clinical and pathologic findings. The link between these two diseases has been extensively studied. Objective: Herein we describe a case of sarcoidosis associated with tuberculosis, treated for tuberculosis, and, 1 year, later presented with a nasal dorsal lump and skin lesions on the extremities. Methods: Case report with clinical description. Results: Our patient had a history of skin and cervical lymphadenopathy symptoms 1 year earlier and was treated with antituberculosis drugs in an outer medical center. Therapy had cured cervical lymphadenopathies, with no improvement in skin lesions. On appearance of the nasal dorsal lump, she presented to our outpatient clinic. We retrieved the previous specimens of the patient, which revealed coexistence of necrotizing granulomas with non-necrotizing granulomas, which was strongly indicative of the coexistence of tuberculosis and sarcoidosis. Radiologic, histopathologic, and microbiologic investigation revealed the diagnosis of sarcoidosis with nasal, cutaneous, and pulmonary involvement. Treatment with prednisolone and hydroxychloroquine resulted in dramatic improvement of nasal bone, pulmonary, and skin lesions within 2 weeks. Conclusion: The clinical presentation of sarcoidosis can be complex, and the differential diagnosis from tuberculosis can be challenging. Atypical clinical pictures also can cause delays in diagnosis and proper management. In patients with granulomatous lesions that are unresponsive to antituberculosis therapy, physicians must be alerted to the possibility of coexistent sarcoidosis. PMID:27103561

Currently, many spine surgeons perform microlumbar discectomies on an outpatient basis. Yet, it is often customary for patients to have a 1-night stay in the hospital. Many studies have shown the efficacy of microlumbar discectomy (MLD) and its preference among surgeons for the treatment of lumbar disc herniation. It has also been shown to be safe, successful, and cost-effective. However, a large comprehensive study of this magnitude, gauging safety, success, and patient satisfaction for these procedures on an outpatient basis has not yet been done. One thousand three hundred seventy-seven MLD procedures have been done from 1992 to 2001 by 1 surgeon. A retrospective chart review was done on all procedures. Patients were then contacted by either telephone or mail to complete an outcome questionnaire. Seven hundred thirteen patients (53.9%) completed the questionnaire. Follow-up questionnaires were not completed due to deaths, incorrect contact information, and refused responses. Out of all MLD procedures, 55 (4.0%) were done with a hospital stay-only 24 of these (1.7%) were originally intended outpatient procedures. Of those that were done on an outpatient basis, 8.6% had a complication, including 6.4% who had a recurrent disc herniation. When asked, 81.6% said they would undergo the procedure again as an outpatient. In 82.1% the surgery's outcome was good, very good, or excellent. MLD is a routine procedure that can be performed on an outpatient basis safely, successfully, and with high patient satisfaction.

To determine if hypopharyngeal surgery for obstructive sleep apnea is associated with significant morbidity in the early post-operative period. Patients with a diagnosis of obstructive sleep apnea who underwent hypopharyngeal surgery at a tertiary care facility between November 2012 and September 2013 were included in this study. Surgical outcomes were assessed from medical records review and a 14 question telephone survey. Results: Twenty-two patients underwent hypopharyngeal surgery for obstructive sleep apnea (OSA). No patient experienced intra-operative complications, post-operative O2 desaturation <90%, prolonged admission for inadequate pain control, pulmonary edema, or airway compromise requiring re-intubation. Post-operative complications included one episode of nasal hemorrhage, one infection requiring hospitalization, and one episode of dehydration treated with IV fluids. 25% of patients experienced some degree of post-operative dysphonia, and 87.5% of patients experienced post-operative dysphagia. The average rating for post-operative pharyngeal pain was 3.5 of 10 by week 3 and 1.75 of 10 by week 4. Most patients described decreased snoring (93.75%), improved feeling of overall health (75%), and increased daytime energy (62.5%). All patients undergoing hypopharyngeal airway surgery were discharged within 23 hours. Hypopharyngeal surgery is a safe and well tolerated procedure for the treatment of OSA. Our findings suggest that hypopharyngeal surgery may be performed on an outpatient basis.

Background. The aim of the present study was to have normative data of nasal bone thickness for use before reconstructive surgery and nasal augmentation through radiography analysis. Methods and Materials. In this descriptive-analytical study, 74 patients were selected from people referred to Radiology Department of Isfahan University for CBCT examination in 2012. Patients with a history of nasal surgery or facial trauma and known congenital anomaly were excluded from the study. Height of nasal bone and width of pyriform aperture and nasal bone thickness in lateral and medial osteotomy line were measured. All these measurements were repeated by two radiologists; finally one sample t-test was performed. Results. The mean thickness of nasal bone on the lateral osteotomy line was 1.92 ± 0.29 mm in females and 1.73 ± 0.32 mm in males (P value = 0.39). The mean thickness of medial osteotomy line was 1.63 ± 0.47 mm in females and 1.94 ± 0.19 mm in males (P value = 0.31). The mean length of nasal bone was 23.5 ± 3.34 mm in females and 25.7 ± 2.96 mm in males (P value = 0.11). The mean width of pyriform aperture was 23.77 ± 2.58 mm in females and 25.67 ± 1.79 mm in males (P value = 0.25). Conclusions. The dimensions of nasal pyramid are known to be significant in choosing suitable osteotome size for reducing surgery side effect. Our results can be used for preoperative estimation of nasal bone dimension of people undergoing reconstructive surgery and augmentation.

Nasal obstruction is often reported by patients. It is a consequence of a subjective feeling of impaired airflow through the nasal cavity. Currently, objective measures of nasal patency rates are very limited. Functional tests only analyze nasal breathing; they do not simultaneously assess airflow through the mouth. The aim of this study is to present a new functional test that assesses a single-stage nasal and oral breathing route. The NOFA (Nasal-Oral Flow Analyzer) is a three-channel flow meter used to perform continuous and simultaneous measurements of nasal and oral respiratory parameters. We present the application of the device and the proposed study protocol. The respiratory tracks of four selected patients are presented. Different breathing patterns are visible: exclusive nasal, exclusive oral, and mixed nasal-oral ventilation pattern. The preliminary results suggest the potential use of the NOFA in ENT practice. Further studies are necessary to evaluate the usefulness of this device in the diagnosis of patients with upper respiratory tract disorders.

Objective To compare the clinical outcomes, including efficacy and complications, of Merocel versus Nasopore as a nasal packing material after nasal surgery. Methods Relevant randomized controlled trials were identified from electronic databases (The Cochrane Library, PubMed, EMBASE, China National Knowledge Infrastructure and Chinese Biomedical Database). Conference proceedings and references from identified trials and review articles were also searched. Outcome measures were pain during nasal packing, pain and bleeding upon packing removal, pressure sensation, nasal blockage, formation of synechiae, mucosal healing, and patients' general satisfaction. Results Seven randomized controlled trials met criteria for analysis. Compared with Merocel, Nasopore significantly reduced patients' subjective symptoms including in situ pain (pain experienced while packing is in place), nasal pressure, pain and bleeding during packing removal, and increased patients' general satisfaction with nasal packing. There were no significant differences in nasal obstruction, adhesion and mucosal healing between the Merocel and Nasopore groups. Conclusions Preliminary evidence suggests that Nasopore may be superior to Merocel as a nasal packing material with regard to in situ pain, pain and bleeding upon removal, pressure, and general satisfaction and does not differ from Merocel in terms of nasal obstruction, tissue adhesion, and long-term mucosal healing.

To study the feature and treatment method of patients with empty sella merger cerebro-spinal fluid leakage of nasal. There were 8 cases with empty sella merger cerebrospinal fluid leakage of nasal, 2 cases were accepted the repairing surgery of cerebrospinal fluid leakage one time, 4 cases were accepted the repairing surgery of cerebrospinal fluid leakage used endoscope 2 times, 1 case was accepted repairing surgery of cerebrospinal fluid leakage used endoscope merge craniotomy and ventricle celiac bypass, 1 case recurrences after repairing surgery of cerebrospinal fluid was recurred after conservative treatment. Some postoperative were stayed in bed for three weeks and lumbar drainage for 1 week. One case of cerebral hemorrhage after surgery was cured with craniotomy, followed for 2 years without recurrence. One case was recurred after conservative treatment. Two cases recurrences after surgery 3 years ago were accepted surgery again followed by one year without recurrence. One case who recurrence 1 year later was accepted repairing surgery of cerebrospinal fluid leakage used endoscope merge craniotomy and ventricle celiac bypass followed six months without recurrence. One cash after once surgery was followed half a year without recurrence. One case with recurrence 5 years later was accepted repairing surgery again. The patient with empty sella combined cerebrospinal fluid leakage of nasal was rare, the main method was endoscopic sinus surgery treatment, but it recurred usually. The patients with repeatedly recurrence can be considered to accepted the surgery of ventricle celiac bypass. It required long-term postoperative follow-up and review.

Rhinologists are often faced with the challenge of assessing nasal breathing from a functional point of view to derive effective therapeutic interventions. While the complex nasal anatomy can be revealed by visual inspection and medical imaging, only vague information is available regarding the nasal airflow itself: Rhinomanometry delivers rather unspecific integral information on the pressure gradient as well as on total flow and nasal flow resistance. In this article we demonstrate how the understanding of physiological nasal breathing can be improved by simulating and visually analyzing nasal airflow, based on an anatomically correct model of the upper human respiratory tract. In particular we demonstrate how various Information Visualization (InfoVis) techniques, such as a highly scalable implementation of parallel coordinates, time series visualizations, as well as unstructured grid multi-volume rendering, all integrated within a multiple linked views framework, can be utilized to gain a deeper understanding of nasal breathing. Evaluation is accomplished by visual exploration of spatio-temporal airflow characteristics that include not only information on flow features but also on accompanying quantities such as temperature and humidity. To our knowledge, this is the first in-depth visual exploration of the physiological function of the nose over several simulated breathing cycles under consideration of a complete model of the nasal airways, realistic boundary conditions, and all physically relevant time-varying quantities.

Nasal fractures are the most common facial fractures and displaced fractures may cause considerable cosmetic concern. Traditionally, displaced nasal fractures have been manipulated under general anaesthesia (GA) performed within 2 weeks of the injury. Despite evidence for the benefit of local anaesthesia (LA), nasal fractures are still most commonly reduced under GA. We have presented a method of reduction of simple nasal fractures under LA in an outpatient setting. This has the advantage of being painless, simple to attempt and cost-effective. If reduction is inadequate then a general anaesthetic reduction is still possible. A recent comprehensive systematic review of all the available evidence did not show any significant difference (in terms of cosmesis, pain or nasal obstruction) between using LA and GA methods and highlighted the evidence base to support LA. We describe our method of assessment and treatment of displaced nasal fractures and provide an online tutorial (http://sciencestage.com/v/22194/local-anaesthetic-nasal-fracture-reduction.html). It is important to keep in mind that any concerns should be referred to an otolaryngology specialist for further management and that practitioners attempting this technique should first receive training from an otolaryngologist.

To define baseline aesthetic dimensions of the nasal aperture in 3 different racial groups. Healthy volunteers from 3 different racial groups (15 white, 15 Chinese, and 15 Indian men) were enrolled in the study at the Department of Otolaryngology, University of Dundee, Dundee, Scotland. Those with a history of nasal or facial surgery or trauma were excluded from the study. Images were obtained and stored in a digital format. The dimensions of nasal aperture were defined by the length of the columella at the narrowest point, the width of the columella at the narrowest point, the length of the nasal aperture at the maximum length, the width of the nasal aperture at the maximum width, and the width of the alar cartilage base. There was no significant difference in the length or the width of the columella for the 3 racial groups. There was no significant difference in the length of the nasal aperture between the Chinese and the white groups. The nasal aperture was longer in the Indian group compared with the other 2 groups (P<.002). The nasal aperture at the maximum width was narrower in the Chinese group compared with the other groups (P<.002); there was no significant difference between the white and Indian groups. The nasal alar width was slightly narrower at the alar base in the Chinese group compared with other racial groups (P<.001). The aesthetic dimensions of the nasal aperture differ between racial groups. The nasal aperture and the alar base were narrower in the Chinese group, and the nasal aperture was longer in the Indian group. The aesthetic surgeon should ideally have an understanding of these ethnic variations.

To assess possible differences in clinical, social, care, and satisfaction profile of patients treated by outpatient clinics or office based psychiatrists. The study sample consists of 100 patients of a psychiatric outpatient clinic and 100 patients treated by office based psychiatrists in the same catchment area. Patients were examined using standardized assessment instruments for severity of illness (HoNOS, CGI), general (GAF) and specific functional impairment (PSP), and satisfaction with psychiatric services (ZUF-8). Chi-square tests, univariate ANOVAs and stepwise multivariate logistic regression models were applied. Compared with patients treated by office based psychiatrists, patients treated by the outpatient clinic showed higher HoNOS and CGI scores, lower GAF and PSP scores, and had more often a disability pension, a legal guardianship, a schizophrenia diagnosis, suicide attempts, hospitalizations, and therapeutic contacts. However, there were no significant differences regarding care satisfaction. The assessed outpatient clinic met the German statutory criteria for its legitimation. However, care needs have to be specified in a better way, and the different care intensity as well as concrete interventions between both settings have to be specified more accurately. © Georg Thieme Verlag KG Stuttgart · New York.

Increasing numbers of plastic surgery procedures are performed in diverse environments, including traditional hospital operating rooms, outpatient surgery centers, and private offices. Just as plastic surgeons develop areas of specialization to better care for their patients, anesthesiologists have specialized in outpatient plastic surgery, both cosmetic and reconstructive. The methods they utilize are similar to those for other procedures but incorporate specific techniques that aim to better relieve preoperative anxiety, induce and awaken patients more smoothly, and minimize postoperative sequelae of anesthesia such as nausea and vomiting. It is important for plastic surgeons to understand these techniques since they are the ones who are ultimately responsible for their patients' care and are frequently called on to employ anesthesiologists for their practices, surgery centers, and hospitals. The following is a review of the specific considerations that should be given to ambulatory plastic surgery patients and the techniques used to safely administer agreeable and effective anesthesia.

This study was designed to evaluate the necessity of postoperative nasal packing and to find factors relevant in determining if nasal packing was required after endoscopic sinus surgery (ESS). From January 2007 through June 2007, 64 consecutive patients who underwent ESS were evaluated. The decision whether or not to perform nasal packing depended on the surgeon's judgment of the bleeding after surgery. Demographic characteristics, medical history, disease extent, surgical procedures, and subjective and objective amount of intraoperative bleeding were analyzed. Postoperative symptoms and endoscopic findings were evaluated also. Forty-eight (75%) of the 64 patients included in this study did not have nasal packing after ESS. One patient from the no-packing group needed nasal packing postoperatively because of persistent nasal bleeding. Symptom scores of nasal obstruction and postnasal drip on the 1st postoperative day were lower in the no-packing group. In unilateral ESS cases, subjectively estimated blood loss and mucosal inflammation scores were lower in the no-packing group. It was observed that preoperative steroid use was more frequent in the packing group. All other parameters did not show significant differences between the two groups. Nasal packing can be safely used less frequently to help the patients experience less discomfort after ESS. The need for nasal packing after ESS can be decided by judicious estimation of bleeding during and after the surgery.

Since the imbalance of the nasal cavities due to nasal septal deviation (NSD) is a commonly observed anatomic variation in healthy adults, clinicians must often decide whether or not it is clinically relevant to the symptoms of nasal airway obstruction (NAO). Main reason for this is a lack of data correlating the symptoms of NAO with objective findings. The aim of our study is to find the correlation between fluid dynamic parameters and the anatomy of nasal cavity with NSD by numerical simulation. We generated 6 computational models of nasal cavities with NSD were created from computed tomographic images: 3 symptomatic patients with NAO and 3 asymptomatic patients. Computational fluid dynamics (CFD) was used to simulate steady inspiratory airflows in each nasal cavity model and compare the fluid dynamic properties of each. In the
