    Nasal tip surgery has been evaluated with respect to correction of the lower lateral cartilages. Indications, techniques, results, and complications related to three generic approaches to the lower lateral cartilages are described. In 673 consecutive rhinoplasties the commonest type of nasal tip surgery was excisional, utilizing either a marginal or cartilage splitting technique. These techniques were utilized: 1. to accomplish debulking, and 2. to accomplish the installation of facets. The excisional technique found its greatest utility in primary rhinoplasties. The version technique, utilizing a change of direction of the thrust of the lower lateral cartilages was utilized in a variety of situations, particularly for the correction of moderately congenitally hypoplastic tip cartilages. It also found great utility in surgery of the Negro or cleft palate nose, increasing tip projection, correcting unacceptable bifidity, and in revision rhinoplasty. Augmentation rhinoplasty, utilizing conchal cartilage as an elastic strut was particularly useful for severe hypoplastic cartilage deficits, the Negro nose, columellar retraction, and alar rim deficits. The overall complication rate of lower lateral rhinoplasty was 17.4 percent. The rate of unacceptable complications related to lower lateral rhinoplasty was 2.7 percent.

  2. Surgery of the nasal septum.

    Long-term results after septoplasty are not satisfactory. Apart from a recurrence of deviation, there are various reasons for this: false preoperative analysis, complete straightening of the septum, and a disturbed nasal cycle. Preoperative functional diagnostics with a combination of rhinoresistometry, acoustic rhinometry, and long-term rhinoflowmetry are necessary for differentiating between "physiological" and "pathological" septal deviations and recognizing other causes for obstruction. The surgical procedure of septoplasty includes approach, mobilization, resection, reposition, and finally reconstruction of all three layers. The goal of the operation should not be complete straightening of the nasal septum. The space between the septum and turbinates is of utmost importance. It should not be enlarged as much as possible; rather, it must be shaped in such a way as to allow freely congestion and decongestion reciprocal on the two sides during the nasal cycle.

    Carbon dioxide (CO2) laser surgery has been shown to be clinically effective in the treatment of nasal allergy. To investigate the mechanisms of eosinophil infiltration and activation underlying the therapeutic effects of CO2 laser surgery, we examined changes in the cytological profile of nasal mucosa after surgery. Twenty-two patients with perennial nasal allergy against house-dust mites underwent two or three rounds of laser surgery at 1-month intervals on an outpatient basis. The following parameters were evaluated at each visit: (i) improvement of clinical symptoms (nasal obstruction, rhinorrhea, and sneezing), (ii) percentage of infiltrating eosinophils in nasal mucosa, and (iii) the degree of EG2+ cells and intracellular adhesion molecule 1 (ICAM-1) expression by immunocytochemistry. All clinical symptoms significantly decreased after surgery. Significant reductions in eosinophil infiltration (p < 0.01) and the percentage of EG2+ cells (p < .005) were observed also. However, the degree of ICAM-1 expression in epithelial cells was not changed. These results suggest that CO2 laser surgery partially reduced the allergic reactions, leading to improvement of clinical symptoms.

    The following article presents nasal septum and turbinate surgery. First an overview with special consideration of the anatomical and physiological background is given followed by indications for surgical procedures. Key steps of the gold standard procedure first described by Cottle and common variations are presented. Furthermore, some techniques dealing with special problems of the septumplasty are discussed followed by an overview on complications and long term results. However, it should be mentioned that studies on surgical procedures of the nasal septum are still not sufficient as higher evidence levels are very rare. Within a separated chapter techniques for closure of septum perforations are presented and indications particularly in the background of the standard procedure of bridge flaps forwarded by Schultz-Coulon are discussed. The second part focusses on turbinate surgery. Accordingly, anatomical and physiological basics are presented followed by indications for surgical procedures and the surgical steps of different procedures as well as postsurgical treatment and long term results.

    The outcomes of aesthetic and functional nasal surgery are difficult to assess objectively due to the intricate balance between nasal form and function. Despite historical emphasis on patient-reported subjective measures, objective measures are gaining importance in both research and the current outcomes-driven healthcare environment. Objective measures presently available have several shortcomings which limit their routine clinical use. In particular, the low correlation between objective and subjective measures poses a major challenge. However, advances in computer, imaging, and bioengineering technology are now setting the stage for the development of innovative objective assessment tools for nasal surgery that can potentially address some of the current limitations. Assessment of nasal form following aesthetic surgery is evolving from two-dimensional analysis to more sophisticated three-dimensional analysis. Similarly, assessment of nasal function is evolving with the introduction of computational fluid dynamics techniques, which allow for a detailed description of the biophysics of nasal airflow. In this paper, we present an overview of objective measures in both aesthetic and functional nasal surgery and discuss future trends and applications that have the potential to change the way we assess nasal form and function.

    A 67-year-old male patient was admitted because of "the right side nasal obstruction repeatedly for 4 years". He got nasal obstruction 4 years ago, especially for the right side nasal cavity, sometimes got blood in his nasal discharge, then the symptom relieved after accepting treatment in local hospital. During the 4 years, the symptom repeatedly occurrence. Three days before hospitalization, the CT examination indicated abnormal things in his nasal cavity and the bone of his nasal sinus had been destroyed. Some abnormal organism were sent to pathological examination, and the report indicated it is acinic cell carcinoma of salivary gland. During the nasal endoscope surgery, a red goiter was found in his nose with its surface crude and brittle. Then we cut the goiter by nasal endoscope, during the operation we find the bottom of the goiter is on the nasal septum. Two weeks after the operation, the patient received the radiation therapy. One year after the operation he doesn't get the abnormal symptom and the nasal MRI not found recidivation. PMID:27373103

    Blood glucose concentration was measured in 84 pediatric patients who were scheduled for outpatient surgery at Chulalongkorn Hospital. They were allocated into 3 groups according to their ages, group 1:less than 1 year of age, group 2:1 to 5 years of age and group 3:over 5 years. The fasting times were approximately 8-12 hours. All patients received standard general anesthesia under mask. No glucose solution was given during operation. Preoperative mean blood glucose were 91.09 +/- 17.34, 89.55 +/- 18.69 and 82.14 +/- 16.14 mg/dl in group 1, 2 and 3 while the postoperative mean glucose values were 129.07 +/- 37.90, 115.62 +/- 29.63 and 111.53 +/- 23.07 mg/dl respectively. The difference between pre- and post-operative values were statistically significant difference (P < 0.01). None of the children had hypoglycemia even when fasting longer than expected. Increased postoperative glucose values may be due to stress response from surgery and anesthesia. We would suggest that the parents give the fluid to their children according to our instructions in order to prevent dehydration and hypoglycemia especially in small infants.

    Study Design Systematic review. Study Rationale As the length of stay after cervical spine surgery has decreased substantially, the feasibility and safety of outpatient cervical spine surgery come into question. Although minimal length of stay is a targeted metric for quality and costs for medical centers, the safety of outpatient cervical spine surgery has not been clearly defined. Objective The objective of this article is to evaluate the safety of inpatient versus outpatient surgery in the cervical spine for adult patients with symptomatic or asymptomatic degenerative disc disease. Methods A systematic review of the literature was undertaken for articles published through February 19, 2014. Electronic databases and the bibliographies of key articles were searched to identify comparative studies evaluating the safety of inpatient versus outpatient surgery in the cervical spine. Spinal cord stimulation, spinal injections, and diagnostic procedures were excluded. Two independent reviewers assessed the strength of evidence using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system, and disagreements were resolved by consensus. Results Five studies that met the inclusion criteria were identified. One study reported low risk of hematoma (0% of outpatients and 1.6% of inpatients). Two studies reported on mortality and both reported no deaths in either group following surgery. Dysphagia risks ranged from 0 to 10% of outpatients and 1.6 to 5% of inpatients, and infection risks ranged from 0 to 1% of outpatients and 2 to 2.8% of inpatients. One study reported that no (0) outpatients were readmitted to the hospital due to a complication, compared with four inpatients (7%). The overall strength of evidence was insufficient for all safety outcomes examined. Conclusion Though the studies in our systematic review did not suggest an increased risk of complication with outpatient cervical spine surgery, the strength of evidence to

    In nasal and sinus surgery, the anaesthetist must share the operating field with the surgeon and take into account some patients' specific pathologies. Bleeding must be avoided by different means but the accurate gesture of the surgeon, added to the properties of the new anaesthetic drugs, may reduce the risk of this functional surgery.

    Due to medical advances in surgery and anesthesia and cost of hospital stays, more elective pediatric surgical procedures are being performed in outpatient settings. One proposed advantage of outpatient surgery is decreased anxiety or a shorter period of anxiety for pediatric patients and their families because they are able to go home shortly after the surgery. A literature review was conducted to describe anxiety experienced by pediatric patients and their families in the outpatient surgery setting and to explore ways to decrease that anxiety. Both children and parents reported not feeling emotionally and educationally prepared for outpatient surgery. Developmentally appropriate pre-surgical educational programs and parental involvement in the surgical experience can help alleviate the anxiety of both children and parents during the pediatric surgical experience. Nurse practitioners (NPs) are currently being used in pre-operative outpatient settings to conduct physical examinations and provide pre-op education. Pre-op education programs provided by NPs are beneficial in decreasing the anxiety state among children and parents prior to 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

    Introduction : The purpose of this study was to quantify anteroposterior facial soft tissue changes with respect to underlying skeletal movements after Le Fort I maxillary advancement surgery by using lateral cephalograms taken before and after the operation. Materials and Methods : The study group consisted of 20 patients (10 women, 10 men; mean age 23.4 ± 1.4 years) having a Class III skeletal deformity caused by a retrognathic maxilla. All patients were treated by Le Fort I maxillary advancement osteotomy. Lateral cephalograms were taken before and 1.6 ± 0.4 years after surgery. Results : The anteroposterior position of A-point and anteroposterior position of maxillary incisor were significantly protracted (-2.69 ± 3.34 and -2.68 ± 3.21, respectively; P < .01). The nasal anteroposterior and superoinferior positions (NASALAP and NASALSI, respectively) were significantly changed (-2.70 ± 6.81, P < .01, and -2.55 ± 5.80, P < .05, respectively) and nasal elevation and protraction were observed after Le Fort I maxillary advancement surgery. Conclusions : The changes in anteroposterior and superoinferior positions of A-point were correlated with the nasal superoinferior position (r = -0.71 , P < .05; r = 0.72, P < .05) after Le Fort I maxillary advancement surgery.

    The current trend in all fields of surgery is towards less invasive procedures with shorter hospital stays. The reasons for this change include convenience to patients, optimal resource utilization, and cost saving. Technological advances in neurosurgery, aided by improvements in anesthesia, have resulted in surgery that is faster, simpler, and safer with excellent perioperative recovery. As a result of improved outcomes, some centers are performing brain tumor surgery on an outpatient basis, wherein patients arrive at the hospital the morning of their procedure and leave the hospital the same evening, thus avoiding an overnight stay in the hospital. In addition to the medical benefits of the outpatient procedure, its impact on patient satisfaction is substantial. The economic benefits are extremely favorable for the patient, physician, as well as the hospital. In high volume centers, a day surgery program can exist alongside those for elective and emergency surgeries, providing another pathway for patient care. However, due to skepticism surrounding the medicolegal aspects, and how radical the concept at first sounds, these procedures have not gained widespread popularity. We provide an overview of outpatient brain tumor surgery in the western world, discussing the socioeconomic, medicolegal, and ethical issues related to its adaptability in a developing nation.

    Background Quantitative methods for comparing intranasal drug delivery efficiencies pre- and postoperatively have not been fully utilized. The objective of this study is to use computational fluid dynamics techniques to evaluate aqueous nasal spray penetration efficiencies before and after surgical correction of intranasal anatomic deformities. Methods Ten three-dimensional models of the nasal cavities were created from pre- and postoperative computed tomography scans in five subjects. Spray simulations were conducted using a particle size distribution ranging from 10–110μm, a spray speed of 3m/s, plume angle of 68°, and with steady state, resting inspiratory airflow present. Two different nozzle positions were compared. Statistical analysis was conducted using Student T-test for matched pairs. Results On the obstructed side, posterior particle deposition after surgery increased by 118% and was statistically significant (p-value=0.036), while anterior particle deposition decreased by 13% and was also statistically significant (p-value=0.020). The fraction of particles that by-passed the airways either pre- or post-operatively was less than 5%. Posterior particle deposition differences between obstructed and contralateral sides of the airways were 113% and 30% for pre- and post-surgery, respectively. Results showed that nozzle positions can influence spray delivery. Conclusions Simulations predicted that surgical correction of nasal anatomic deformities can improve spray penetration to areas where medications can have greater effect. Particle deposition patterns between both sides of the airways are more evenly distributed after surgery. These findings suggest that correcting anatomic deformities may improve intranasal medication delivery. For enhanced particle penetration, patients with nasal deformities may explore different nozzle positions. PMID:22927179

    Background: Cocaine is often used topically to provide the profound vasoconstriction required for nasal surgery; however, it has been associated with intraoperative cardiac adverse effects. We compared cocaine with phenylephrine as an alternative to ascertain their relative efficacy as vasoconstrictors in nasal septoplasty. Methods: Adult patients, presenting for elective nasal septoplasty, of American Society of Anaesthesiologists physical status I-III, were randomised to either 0.5% phenylephrine or 4% cocaine. The primary outcome was quality of vasoconstriction on a 5-point scale (1=unacceptable, 5=excellent), rated by the surgeon at the end of the procedure. Results: Twenty-nine patients received phenylephrine and 26 received cocaine. The median rating for quality of the vasoconstriction was 4.0 (good) in both the phenylephrine and cocaine groups (P=0.84). Median blood loss was 50 ml in the phenylephrine group and 62.5 ml in the cocaine group (P=0.49). In secondary analyses, phenylephrine was shown to be non-inferior to cocaine on both quality of vasoconstriction (non-inferiority delta of 1 point, P=0.009) and estimated blood loss (non-inferiority delta of 25 ml, P=0.028). The frequency of ventricular ectopy, ST segment changes or blood pressure changes after nasal packing was not significantly different between the two groups. Conclusion: Phenylephrine in a concentration of 0.5% is not different from 4% cocaine on the quality of vasoconstriction in septoplasty. Given the abuse potential of cocaine and the added administrative burden associated with its handling, phenylephrine might serve as an alternative. PMID:23825816

    2013-01-01

    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

We present the successful use of a patient's own nasal PAP machine in the operating room during outpatient foot surgery which required addition of a straight adaptor for oxygen delivery and careful positioning of the gas sampling line to permit end-tidal carbox dioxide monitoring. Home PAP machines may provide a potential alternative to more invasive methods of airway management for patients with obstructive sleep apnea under moderate sedation. PMID:27169990

    A greater emphasis on day case surgery within the health service is seen as a method of improving efficiency and reducing expenditure. We interviewed 90 consecutive patients undergoing nasal surgery who had been preoperatively assessed as being fit for day case surgery. They were randomised into three groups regarding the duration of postoperative nasal packing. All patients stayed overnight following surgery and were interviewed prior to discharge. Some 52% of the overall sample would be happy to have nasal surgery performed as a day case. If the nasal pack was removed after two hours, this figure rose to 67%. This difference in patient acceptance did not attain statistical significance overall, but there was a significant difference in those undergoing submucosal resection. There was no difference in the age, sex distribution or type of surgery performed between each group. The audit commission quotes patient satisfaction with day case surgery at 80%. Nasal surgery was not examined in their report, but was included as one of a set of procedures suitable for consideration. Although day case nasal surgery may be safe, further research regarding patient acceptance is required.

    Relative to outpatient surgery in hospital settings, ambulatory surgery centers (ASCs) are more efficient and associated with a lower cost per case. However, these facilities may also spur higher overall procedure utilization and thus lead to greater overall health care costs. The authors used the State Ambulatory Surgery Database from the State of Florida to identify Medicare-aged patients undergoing 4 common ambulatory procedures in 2006, including knee arthroscopy, cystoscopy, cataract removal, and colonoscopy. Hospital service areas (HSAs) were characterized according to ASC market share, that is, the proportion of residents undergoing outpatient surgery in these facilities. The authors then examined relationships between ASC market share and rates of each procedure. Age-adjusted rates of ambulatory surgery ranged from 190.5 cases per 1000 to 320.8 cases per 1000 in HSAs with low and high ASC market shares, respectively (P < .01). For all 4 procedures, adjusted rates of procedures were significantly higher in HSAs with the highest ASC market share. The greatest difference, both in relative and absolute terms, was observed for patients undergoing cystoscopy. In areas of high ASC market share, the age-adjusted rate of cystoscopy was nearly 3-fold higher than in areas with low ASC market share (34.5 vs 11.9 per 1000 population; P < .01). The presence of an ASC is associated with higher utilization of common outpatient procedures in the elderly. Whether ASCs are meeting unmet clinical demand or spurring overutilization is not clear.

    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.

    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.

  6. Does procedure profitability impact whether an outpatient surgery is performed at an ambulatory surgery center or hospital?

    2011-07-01

    Ambulatory surgery centers (ASCs) are small (typically physician owned) healthcare facilities that specialize in performing outpatient surgeries and therefore compete against hospitals for patients. Physicians who own ASCs could treat their most profitable patients at their ASCs and less profitable patients at hospitals. This paper asks if the profitability of an outpatient surgery impacts where a physician performs the surgery. Using a sample of Medicare patients from the National Survey of Ambulatory Surgery, we find that higher profit surgeries do have a higher probability of being performed at an ASC compared to a hospital. After controlling for surgery type, a 10% increase in a surgery's profitability is associated with a 1.2 to 1.4 percentage point increase in the probability the surgery is performed at an ASC.

Physicians who own ASCs could treat their most profitable patients at their ASCs and less profitable patients at hospitals. This paper asks if the profitability of an outpatient surgery impacts where a physician performs the surgery. Using a sample of Medicare patients from the National Survey of Ambulatory Surgery, we find that higher profit surgeries do have a higher probability of being performed at an ASC compared to a hospital. After controlling for surgery type, a 10% increase in a surgery's profitability is associated with a 1.2 to 1.4 percentage point increase in the probability the surgery is performed at an ASC.

    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

    Objective: Communication between the patient and physician is central to medical care. However communication skills in Turkey haven’t been gained so much concern. This situation effect the national quality of health care. Here, we tried to perform some basic communication skills and to find the problems with the possible solution suggestions. Materials and Methods: The study was conducted for a month in general surgery outpatient department located in the slum part of Ankara with low socio-economic population. Basic communication skills were performed. The age, sex, education levels of the patients were obtained. Total symptom expression and interview time were recorded. Previous medical histories were asked. Interruptions including telephone, door knocking were noted. The questions of the patients at the end of the interview classified as hospital setting, nutrition and treatment. Results: Total 410 interviews were analysed. Mean symptom expression and interview times were 22.9 sec and 7.05 min, respectively. Educated patients, males and young patients expressed symptoms longer than the others (p<0.05). There were 174 interruptions in which total interview time signifantly increased than the non interrupted ones (p<0.05). Final questions about hospital setting were signifantly higher in illiterate patients than the educated ones (p<0.05). Awareness of medical history is higher in educated and young patients. Conclusion: Basic communications skills can be performed whether in rural regions. Much more concern should be given to the education of communication skills. The obstacles in communication in medicine are low education levels, and unorganised health system. PMID:26644767

    Diffuse nasal polyposis remains a challenge despite recent improvements in endonasal surgery. The purpose of this study is to evaluate the results after a radical complete sphenoethmoidectomy with peroperative and postoperative frontal irrigation in cases of diffuse nasal polyposis. In this prospective study, we include 50 consecutive patients with diffuse nasal polyposis suffering from nasal obstruction, anosmia, and other symptoms of chronic sinusitis. All patients were refractory to medical therapy. In each patient an endoscopic complete sphenoethmoidectomy including total excision of all diseased ethmoid mucosa was performed. Preoperative and postoperative frontal irrigation was performed systematically. The patients were followed closely with serial endoscopic examination, and CT scanning was performed between 2 and 3 years after surgery. There were no complications. Thirty-nine of the 50 patients regained satisfactory olfaction. Partial nasal obstruction persisted in four of the 50 patients. Endoscopically, polyp recurrence was noted in 3% of posterior ethmoids, 23% of anterior ethmoids, and 50% of frontal recesses. We conclude that in cases of refractory and extensive nasal polyposis, a total sphenoethmoidectomy with perioperative frontal irrigation followed by long-term postoperative topical steroid therapy provides excellent improvement or cure with safety and reliability.

    Background and Objectives. Nasal obstruction due to deviated nasal septum is a common problem bringing a patient to an otorhinolaryngologist. Occasionally, these patients may also complain of olfactory impairment. We proposed to study the effect of septal deviation on the lateralised olfactory function and the change in olfaction after surgery of the septum (septoplasty). Methods. Forty-one patients with deviated nasal septum were evaluated for nasal airflow, olfactory score, and nasal symptomatology. Septoplasty was done under local anesthesia. Pre- and postoperative olfactory scores, airflow and olfactory scores, and nasal symptomatology and olfactory scores were compared and correlated. Results. The range of preoperative composite olfactory score (COS) on the side of septal deviation was 4–14 (mean 7.90 ± 2.234) and on the nonobstructed side was 9–18 (mean 14.49 ± 2.378). Severity of deviated nasal septum and preoperative COS of diseased side were correlated and the correlation was found to be significant (rho = −0.690, p = 0.000 (<0.001)). The preoperative mean COS (7.90 ± 2.234) was compared with the postoperative mean COS (12.39 ± 3.687) and the improvement was found to be statistically significant (p = 0.000 (<0.001)). Conclusion. We found improvement in olfactory function in 70.6% patients after surgery, no change in 20.1%, and reduced function in 7.6%. With the limitation of a small sample size and a potential repeat testing bias, we would conclude that correction of nasal septal deviation may lead to improvement in sense of smell. PMID:26491724

    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. PMID:22465001

  14. Ultrasound Screening for Deep Venous Thrombosis Detection: A Prospective Evaluation of 200 Plastic Surgery Outpatients

    PubMed Central

    2015-01-01

    Background: Our understanding of the pathophysiology of venous thromboembolism is largely based on the experience of orthopedic patients undergoing total joint replacement. Little is known regarding the natural history of venous thromboembolism in plastic surgery outpatients. Today, ultrasound screening, including compression and Doppler color flow imaging, represents the standard for detecting deep venous thromboses. Methods: Ultrasound screening was offered to 200 consecutive plastic surgery outpatients undergoing 205 operations. Patients were scanned before surgery, on the day after surgery, and approximately 1 week after surgery. No patient declined to participate (inclusion rate, 100%). Spontaneous breathing, Avoid gas, Face up, Extremities mobile anesthesia was used, with no chemoprophylaxis. Patient surveys were administered. Results: Six hundred ultrasound screening tests were performed. All scans performed the day after surgery were negative. Only one examination was positive, 8 days after a lipoabdominoplasty. Subsequent scans revealed complete resolution of the thrombosis with anticoagulation. Ninety percent of surveyed patients would choose to have ultrasound screening in the future. Conclusions: The natural history of thromboembolism in plastic surgery outpatients differs from orthopedic patients. The risk of a deep venous thrombosis in a patient treated with Spontaneous breathing, Avoid gas, Face up, Extremities mobile anesthesia is approximately 0.5%. Thromboses are unlikely to develop intraoperatively. In the single affected patient, the thrombosis was located distally, in a location that is less prone to embolism and highly susceptible to anticoagulation. Ultrasound screening is an effective and highly feasible method to identify affected patients for treatment. PMID:25878943

  15. Safe, efficient, and cost-effective orthognathic surgery in the outpatient setting.

    PubMed

    Farrell, Brian B; Tucker, Myron R

    2009-10-01

    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 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

    2015-01-01

    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

    Background: Pain relief after surgery is an essential component of postoperative care. Objectives: The purpose of this study was to compare the efficacy of intravenous acetaminophen and intravenous meperidine in pain relief after outpatient urological surgery. Patients and Methods: 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. Results: 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. Conclusions: Intravenous acetaminophen reduced pain following outpatient urological surgery more significantly than meperidine. PMID:25798377

    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

  3. New modalities of pain treatment after outpatient orthopaedic surgery.

    Beaussier, M; Sciard, D; Sautet, A

    2016-02-01

    Postoperative pain relief is one of the cornerstones of success of orthopaedic surgery. Development of new minimally-invasive surgical procedures, as well as improvements in pharmacological and local and regional techniques should result in optimal postoperative pain control for all patients. The analgesic strategy has to be efficient, with minimal side effects, and be easy to manage at home. Multimodal analgesia allows for a reduction of opiate use and thereby its side effects. Local and regional analgesia is a major component of this multimodal strategy, associated with optimal pain relief, even upon mobilization, and it has beneficial effects on postoperative recovery. Ultrasound guidance improves the success rate of distal nerve blocks and makes distal selective blockade possible, helping to preserve the limb's motility. Besides peripheral nerve blocks, local infiltration (incisional and/or intra-articular) is also important to consider. Duration of the nerve blockade is limited after a single injection. This must be taken into consideration to avoid the recurrence of pain when the patient returns home. Continuous perineural blocks using catheters are an option that can be easily managed at home with monitoring by home-care nurses. Extended-release liposomal bupivacaine and adjuvants such as dexamethasone could significantly enhance the duration of the sensory block, thereby reducing the indications for pain pumps. Non-pharmacological approaches, such as cryotherapy, hypnosis and acupuncture should not be ignored. PMID:26803223

    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%.

    There has been increased interest in and experience with performing several surgical procedures on the hand and the wrist utilizing local anesthesia in an unsedated patient. These surgical procedures can be safely performed on an outpatient basis. Experience has shown that the strategic use of local anesthesia with epinephrine is safe and, in procedures such as tendon repair or transfer, permits intraoperative control of overall motion and function.

    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. PMID:20361342

    The records were reviewed of 406 patients with carcinoma of the large bowel who had been treated at the Middlesex Hospital during 1958-62. Of these patients, 180 were followed up regularly in this hospital after radical surgery, and from six months to 15 years after operation they were seen 2319 times; 71 developed a recurrent carcinoma but, of these, 41 recurrences (58%) were diagnosed at times other than those of the patients' routine outpatient appointments, although they were being regularly reviewed. Only one patient with recurrence appeared to have been cured by further surgery. For the present, adequate education of patients in the symptoms of early recurrence, with instruction to return if any of these develop, is likely to be more effective than the unsatisfactory and time-consuming routine follow-up still used in many hospitals.

    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

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.

    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.

    The pharmaceutical services provided to the outpatient surgery center of a health maintenance organization (HMO) are described. The satellite pharmacy is managed by the nearby central pharmacy. The satellite pharmacist prepares and dispenses all needed medications and i.v. admixtures, maintains the inventory of all drugs and i.v. supplies, and supplies clinical and drug information. The pharmacist ensures that i.v. admixtures are made according to guidelines, that drug interactions and drug allergies are guarded against, and that each patient has access to oral pain medications and medication counseling while still in the recovery room. The tighter inventory control created by this arrangement helps to reduce costs, and the surgical nursing staff has been relieved of many medication-related activities. The presence of the pharmacist in the surgery center also allows for more accurate documentation of controlled-drug dispensing. The presence of a pharmacist in the surgery center has ensured strict control of drug use and enabled nurses to spend more time on direct patient care. PMID:2309723

    2016-07-01

    In the US, safe and effective same-day discharge of patients, following uncomplicated, ambulatory surgery, also referred to as outpatient surgery, significantly reduces the nursing hours spent caring for patients who do not require hospital admission. Data from the last three decades show that same-day discharge for patients who undergo approved outpatient surgical procedures carries no higher risk of complications than for those who stay for 24-hour observation. This article describes a service development project which evaluated patients' perceived preparedness for same-day discharge. Results suggest that a standardised approach to managing potential complicating factors, such as pain and patients' expectations, can increase the number of successful same-day discharges. The terms outpatient and ambulatory are used interchangeably in the article, and refer to surgical procedures for which inpatient admission is not considered necessary by patients' insurance providers.

    The majority of studies have shown that the use of functional endoscopic sinus surgery (FESS) leads to symptomatic improvement in 73-98.4 % of patients with chronic rhinosinusitis and nasal polyposis (NP). The aim of the study is to evaluate clinical outcomes and quality of life (QoL) in patients with NP after FESS. The prospective study included 85 consecutive adult patients (≥18 years) with NP who were operated on using FESS after failure of the medicamentous treatment and in certain cases of surgical treatment. QoL was assessed by Short Form-36 Health Survey (SF-36) questionnaire, and the symptom intensity was presented using visual analogue scale (VAS). The objective finding was presented as endoscopic and computerized tomography (CT) score. The intensity of each symptom, the values of symptom scores (major, minor and total), the values of dimension scales and summary scales of the QoL, as well as the values of endoscopic score through three periods of time (pre-surgery, 6 and 12 months after the surgery) were analyzed. Following the FESS, mean intensity values of all individual symptoms and symptom scores were significantly lower and the values of all dimension scales and summary scales of QoL were significantly higher (p < 0.05). There was no statistically significant difference in symptom intensity and QoL after 6 and 12 months of surgical treatment (p > 0.05). Endoscopic score was on average significantly lower after 6 and 12 months of FESS (p < 0.05), but the mean score value after 12 months of operation was significantly higher in relation to that after 6 months of surgery (p < 0.05). Nevertheless, the recurrence of NP was observed in 28 patients (32.9 %) in the follow-up period. In conclusion, FESS in NP patients results in significant improvement of symptom intensity, QoL and endoscopic score. While the intensity of symptoms and QoL showed a tendency to maintain between 6 and 12 months after surgery, endoscopic score showed a tendency of exacerbation

    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.

    Objective. To evaluate the effect of turbinate sizes on the titrated continuous positive airway pressure (CPAP) therapeutic treatment pressures for patients with obstructive sleep apnea (OSA) who have not had nasal surgery. Study Design. Retrospective case series. Methods. A chart review was performed for 250 consecutive patients. Results. 45 patients met inclusion criteria. The mean ± standard deviation (M ± SD) for age was 54.6 ± 22.4 years and for body mass index was 28.5 ± 5.9 kg/m2. The Spearman's rank correlation coefficient (rs) between CPAP therapeutic treatment pressures and several variables were calculated and were weakly correlated (age rs = 0.29, nasal obstruction rs = −0.30), moderately correlated (body mass index rs = 0.42 and lowest oxygen saturation rs = −0.47), or strongly correlated (apnea-hypopnea index rs = 0.60 and oxygen desaturation index (rs = 0.62)). No statistical significance was found with one-way analysis of variance (ANOVA) between CPAP therapeutic treatment pressures and inferior turbinate size (right turbinates p value = 0.2012, left turbinate p value = 0.3064), nasal septal deviation (p value = 0.4979), or mask type (p value = 0.5136). Conclusion. In this study, CPAP titration based therapeutic treatment pressures were not found to be associated with inferior turbinate sizes; however, the CPAP therapeutic treatment pressures were strongly correlated with apnea-hypopnea index and oxygen desaturation index.

    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.

    2014-01-01

    Objective To examine rehabilitation preferences, participation and determinants for the choice of a certain rehabilitation setting (inpatient vs. outpatient) and setting-specific rehabilitation outcomes. Methods The longitudinal observational study referred to 534 consecutive disc surgery patients (18–55 years). Face-to-face baseline interviews took place about 3.6 days after disc surgery during acute hospital stay. 486 patients also participated in a follow-up interview via telephone three months later (dropout-rate: 9%). The following instruments were used: depression and anxiety (Hospital Anxiety and Depression Scale), pain intensity (numeric analog scale), health-related quality of life (Short Form 36 Health Survey), subjective prognosis of gainful employment (SPE-scale) as well as questions on rehabilitation attendance, return to work, and amount of sick leave days. Results The vast majority of patients undergoing surgery for a herniated disc attended a post-hospital rehabilitation treatment program (93%). Thereby two-thirds of these patients took part in an inpatient rehabilitation program (67.9%). Physical, psychological, vocational and health-related quality of life characteristics differed widely before as well as after rehabilitation depending on the setting. Inpatient rehabilitees were significantly older, reported more pain, worse physical quality of life, more anxiety and depression and a worse subjective prognosis of gainful employment before rehabilitation. Pre-rehabilitation differences remained significant after rehabilitation. More than half of the outpatient rehabilitees (56%) compared to only one third of the inpatient rehabilitees (33%) returned to work three months after disc surgery (p<.001). Conclusion The results suggest a “pre-selection” of patients with better health status in outpatient rehabilitation. Gaining better knowledge about setting-specific selection processes may help optimizing rehabilitation allocation procedures and

    2000-01-01

    BACKGROUND/AIM—Hypoxia and carbon dioxide rebreathing are potential problems during eye surgery in spontaneously breathing patients. The aim of the present study was to determine effectiveness of nasal application of oxygen to prevent hypoxia and carbon dioxide accumulation in spontaneously breathing patients undergoing cataract surgery.
METHODS—Oxygenation and carbon dioxide rebreathing were examined in 40 elderly patients using two different methods of oxygen supply—nasal v ambient air—with a constant flow of 2 l/min. Partial pressure of carbon dioxide under ophthalmic drapes, transcutaneous pressure of carbon dioxide, and the respiratory rate were measured during 25 minutes while oxygen was supplied via a nasal cannula or into the ambient air under the drapes.
RESULTS—In both groups carbon dioxide accumulation under the drapes, carbon dioxide rebreathing, tachypnoea, and an increase in peripheral oxygen saturation occurred. No significant differences were found between the two methods.
CONCLUSION—Nasal application of oxygen prevented hypoxia but did not prevent carbon dioxide accumulation in patients undergoing eye surgery under retrobulbar anaesthesia. Additionally, as a side effect when using nasal probes, irritation of the nose was described in half of the patients investigated.

    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

    The inferior turbinates of 140 patients with perennial allergic rhinitis were vaporized by a defocused carbon dioxide (CO2) laser beam, using specially designed handpieces. Among these patients, 131 showed improvement in subjective symptoms one month after laser surgery. Excellent or good results were obtained in 27 of 35 patients who were followed up more than one year after laser surgery. The histopathologic changes observed in the nasal mucous membrane after surgery were fibrous proliferation and scar formation in the superficial layer of the submucosa. This surgery can be done under surface anesthesia as an outpatient procedure, and it is painless, with no bleeding.

    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]).

    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. PMID:16163102

    Aim: To evaluate the effect of intravenous (IV) clonidine premedication for the bloodless surgical field in patients undergoing middle ear or nasal surgery comparing three different doses. Subjects and Methods: This prospective randomized, clinical trial was performed on 90 normotensive patients belonging to American Society of Anesthesiologists grade I/II, aged 18–60 years, of either sex, undergoing routine middle ear or nasal surgery. These patients were divided into three Groups A, B, and C with 30 patients in each according to the dose of IV clonidine used as premedicant that is 3, 4, and 5 µg/kg, respectively. The hypotensive period commenced 10 min after the start of surgery till the surgeon's request for no hypotension required any longer. The target mean blood pressure for producing bloodless surgical field was 60–70 mmHg. During the hypotensive period, the surgeons were asked to rate the bleeding severity score on a six-point scale from 0 (no bleeding) to 5 (severe bleeding). Statistical Analysis Used: ANOVA, Chi-square test, Z-test, standard deviation and P value. Results: IV clonidine premedication in a dose of 4 and 5 µg/kg reduces bleeding and provides a clear field for surgery. It also reduces the requirement of isoflurane, fentanyl, and metoprolol for controlled hypotension. However, clonidine 5 µg/kg was not more effective than clonidine 4 µg/kg in producing these effects rather was associated with some side effects. Conclusion: IV clonidine premedication in a dose of 4 µg/kg is safe and effective for producing a bloodless surgical field in the middle ear and nasal surgery. PMID:26712981

    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.

  13. Nasal packing and stenting

    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

    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. PMID:27423279

    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.

    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. PMID:27533764

    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.

    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 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. PMID:21425063

    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.

    This study prospectively examined the intranasal distribution of nasal spray after nasal septal correction and decongestant administration. A cohort of 20 patients was assessed for the distribution of nasal spray before and after nasal septum surgery. Sprays were dyed and administered one puff per nostril when patients hold their head up in an upright position. Before and after decongestant administration, the intranasal distribution was semi-quantitatively determined by nasal endoscopy. The results showed that the dyed drug was preferentially sprayed onto the nasal vestibule, the head of the inferior turbinate, the anterior part of septum and nasal floor. As far as the anterior-inferior segment of the nasal cavity was concerned, the distribution was found to be influenced neither by the decongestant nor by the surgery (P>0.05). However, both the decongestant and surgery expanded the distribution to the anatomical structures in the superior and posterior nasal cavity such as olfactory fissure, middle turbinate head and middle nasal meatus. No distribution was observed in the sphenoethmoidal recess, posterior septum, tail of inferior turbinate and nasopharynx. It was concluded that nasal septum surgery and decongestant administration significantly improves nasal spray distribution in the nasal cavity. PMID:22173509

    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.

    We have used the carbon dioxide (CO(2)) laser and the gallium aluminium arsenide (GaAlAs) diode laser with flexible fiber delivery instruments for vaporization of the inferior nasal turbinate in pediatric patients since 1993. Under endoscopic control, the whole inferior turbinate was vaporized by 5-10 W laser output delivered via an optical fiber. Generally, the nasal mucosa changes into normal mucosa, and symptoms improve. The greatest symptomatic improvement was in nasal obstruction. The results obtained by the two laser devices were similar although they have had different characteristics. Endoscopic laser surgery is effective in the treatment of pediatric nasal allergy.

    The incidence of mucocoeles associated with a non-surgically treated nasal polyposis is rare. We report a rare case of nasal polyposis with asymptomatic frontal mucocoeles in a 28-year-old Malay man who presented with bilateral nasal obstruction with anosmia. Physical examination revealed bilateral grade III nasal polyps causing obstruction. Computed tomography revealed paranasal polyposis with a large polyp extending and expanding the posterior table of the frontal sinus causing erosion and thinning of its wall. Marsupialisation of the mucocoele and nasal polypectomy were done. Endoscopic sinus surgery and marsupialisation should be the treatment of choice for asymptomatic frontal mucocoele.

    We report a case of unilateral mydriasis following nasal electrocautery presumed to be the result of retrograde flow of adrenaline and/or xylometazoline hydrochloride (Otrivine) through the nasolacrimal duct into the eye. We review the literature and highlight the importance of correct interpretation of finding a dilated pupil post-operatively. To our knowledge. we report the first such case involving xylometazoline hydrochloride and also following nasal electrocautery. Unilateral mydriasis is alarming after nasal surgery but must be interpreted with caution. During minimally invasive procedures it is likely to be due to the effects of topical medication to the nose rather than surgical trauma. PMID:21158576

    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.

    Management of the cleft lip nasal deformity offers a unique and ongoing challenge in facial plastic surgery. Although there has been no consensus regarding the optimal timing and technique for surgical repair of this deformity, the authors have found a three-tiered approach to be satisfactory. This approach involves a primary rhinoplasty performed at the time of the initial cleft lip repair to address reconstruction of the nasal floor and sill, columellar lengthening, repositioning of the alar base, and repositioning of the skin and mucosa of the lower lateral cartilage. Following alveolar bone grafting, an intermediate rhinoplasty is often performed at 6 to 10 years of age through an open approach to correct the cartilaginous lower nasal deformity. A delayed rhinoplasty is then performed in the later teenage years to correct the bony dorsal deformity and the various causes of nasal obstruction.

    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.

    With increased experience, many laparoscopic procedures have evolved from mandatory same-day admission to the outpatient setting. Given the shorter operative time and length of stay, the potential to perform robotic surgery as an outpatient procedure exists. We sought to describe our initial experience with performing robotic-assisted laparoscopic pyeloplasty (RP) on children in an outpatient setting. We retrospectively reviewed a prospectively collected database of all patients undergoing RP from July 2012 to May 2014 by a single surgeon. All patients discharged home within 12 h of completion of surgery were included in the analysis. Prior to discharge the Wong-Baker Pain Scale 1-10 was reviewed and given to all patients. All patients were prescribed oxybutynin and phenazopyridine for bladder spasms and stent discomfort. Post-operative follow-up telephone calls were made inquiring about oral intake, pain control, constitutional symptoms, and voiding issues. Readmission rates and post-operative outcomes were reviewed. During the study period, 62 children underwent RP and 13 patients (21 %) were selected for outpatient management. These 7 boys and 6 girls had a mean age of 8.1 years old. Of the 13 patients, 11 patients had left-sided procedures and 2 had right; all had primary UPJO. Mean pain score was 2.7 in the first 12 h at home. Within 24 h, the pain score decreased to a mean of 2.2. No patient required opioid analgesics and no child required admission after surgery. At 3-month follow-up, 7 patients had resolved hydronephrosis, 5 had improved hydronephrosis and 1 was unchanged. MAG3 renal scan in the latter patient showed no sign of obstruction. Outpatient RP is feasible and appears to be safe. Great care must be taken when selecting which patients can be fast tracked. PMID:27026272

    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

    Nasal lobular capillary hemangioma is a rare benign tumor of the paranasal sinuses. This lesion is believed to grow rapidly in size over time. The exact etiopathogenesis is still a dilemma. We discuss a case of nasal lobular capillary hemangioma presenting with a history of epistaxis. Contrast enhanced computed tomography of paranasal sinuses revealed an intensely enhancing soft-tissue mass in the left nasal cavity and left middle and inferior meati with no obvious bony remodeling or destruction. We present imaging and pathologic features of nasal lobular capillary hemangioma and differentiate it from other entities like nasal angiofibroma. PMID:24228209

    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.

    Depression is a common condition that often responds to a variety of treatment modalities. Concerns about antidepressant medications' safety and efficacy and individuals' lack of response or their problems complying with medication regimens have prompted a resurgence in electroconvulsive therapy (ECT) for specific mental health conditions. Outpatient maintenance ECT, performed under general anesthesia, is a safe, effective follow-up treatment for individuals with major depression who have undergone inpatient ECT. Individuals with bipolar disorders, catatonia, mania, and schizophrenia and those with Parkinson's disease also can benefit from outpatient ECT. Perioperative nursing care for individuals who undergo outpatient ECT is similar to the care provided to patients scheduled for ambulatory surgery. Successful performance of outpatient ECT requires collaboration by skilled perioperative nurses, psychiatrists, anesthesia care providers, affected individuals, and family members.

  15. Parameters of nasal airway anatomy on magnetic resonance imaging correlate poorly with subjective symptoms of nasal patency.

    1999-09-01

    Forty-four patients undergoing magnetic resonance imaging (MRI) head scans for non-nasal disease were asked to complete a questionnaire immediately after the scan. Subjective patency was scored for each nasal airway, patients were also asked about other nasal symptoms, hay fever, upper respiratory tract infections, medication and any history of nasal surgery or trauma. The following measurements from MRI scans were made: the cross-sectional area of the nasal airway at the anterior end of the middle turbinate, the horizontal width of the inferior turbinate and maximum septal mucosal thickness. In addition the presence of any septal deviation and the thickness or the mucosa of the paranasal sinuses was assessed. Correlation between subjective airway patency and the anatomical parameters studied was generally very weak. However, patients with sinus mucosal thickening on MRI scanning had significantly lower subjective patency scores (left P = 0.003, right P = 0.029) for both nasal airways. Assessment of the nasal airway on MRI correlates poorly with symptoms of nasal obstruction. However, patients with sinus mucosal thickening (> 5 mm) had significantly more symptoms of nasal obstruction on both sides.

    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.

    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.

    The aim of this study was to analyze the cases that were reexplored shortly after closed reduction of the nasal bone fracture. From 1996 to 2009, 955 patients (757 males and 198 females) were operated on for the nasal bone fractures. The nasal splints were applied and removed 1 week postoperatively, and the results of nasal reduction were reviewed. Indications for reexploration were undercorrection or deviation of the reduced nasal bone.Of the 955 patients, 13 (11 males and 2 females; 1.36%) were reexplored. The recorrection was done 7.78 +/- 4.77 days after the initial surgery. Mostly local anesthesia was carried out on the reoperation of 11 patients. All 13 patients were satisfied with the final result.If any undercorrection or deviation is persistent, the corrective reexploration should be discussed with the patient in detail and corrective reexploration should be planned soon.

    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.

  2. An approach to the nasal septum in children.

    PubMed

    Healy, G B

    1986-11-01

    Surgery of the nasal septum has long been discouraged in the pediatric population. Concerns about growth and development of the nose have led surgeons to adopt an extremely cautious attitude toward the correction of nasal septal deformities in childhood. More recently, studies have shown that with proper preservation of septal cartilage, surgery can be safely undertaken in this area. Frequently, however, exposure to the nasal septum is limited in small children due to the size of the nasal vestibule. Sublabial septoplasty has been safely carried out now in ten patients ranging in age from 4 to 9 years. This approach allows for complete access to the nasal septum while avoiding any external cosmetic deformity. The nasal septum has been preserved in all cases through morsalization and repositioning. Growth and development of the nose has been followed for up to 60 months without evidence of deformity or alteration. Sublabial septoplasty would, therefore, appear to be a safe and cosmetically acceptable approach to the correction of severe nasal septal deformities of childhood. PMID:3773624

    Objective Despite the many complications of succinylcholine, it is still widely used as a superior muscle relaxant for rapid sequence induction. One of these complications is postoperative myalgia (POM). The aim of this study was to investigate the prophylactic effect of low-dose ketamine on the incidence and severity of POM. Materials and methods In this double-blind clinical study, a total of 148 patients scheduled for general anesthesia were randomly divided into two equal groups. Initially, in Group K, 0.5 mg/kg of ketamine was injected intravenously, whereas in Group N, the same volume (5 mL) of normal saline was injected. Thereafter, anesthesia was induced in all patients, by injecting 1.5 mg/kg of fentanyl and 2 mg/kg of propofol intravenously. Following the loss of eyelid reflex, 1.5 mg/kg of succinylcholine was injected intravenously as a muscle relaxant and then the patients were intubated. POM was defined as a pain with no surgical interferences, and its intensity was graded based on a four-point scale. The incidence and severity of myalgia were assessed by a blinded observer 24 hours after surgery. Results In terms of demographic data, the results of this study showed that there is no significant difference between patients in both groups (P>0.05). Overall, the incidence of POM in Group K was significantly less, when compared with Group N (P<0.05), but both groups were comparable based on the grade 2 of POM. After the induction of anesthesia, the systolic and diastolic blood pressure values were found to reduce in both groups (P<0.05). However, the changes were somehow similar, and repeated measures of variance analysis showed no significant difference in the two study groups (P>0.05). Conclusion The addition of 0.5 mg/kg of ketamine to propofol for the induction of anesthesia can be effective in reducing the incidence of low-grade POM. PMID:27462175

    The nose plays a primary role within the airways, working as a filter and air-conditioner, together with other important functions. Thus, it is not surprising that nasal diseases are associated with several other comorbidities, including both upper and lower airways, such as bronchial hyperresponsiveness (BHR) and asthma. Several studies have investigated the relationship existing between the upper and the lower airways and new insights are rising. Nevertheless, some uncertainties still remain, mainly because nasal disorders are quite heterogeneous, overlapping (i.e. rhinitis-rhinosinusitis-sinusitis, acute or chronic, allergic or non-allergic) and difficult to diagnose, so that, frequently, many studies don’t differentiate between the various conditions. For this reason, the purpose of this review is to systematically analyze present epidemiological, pathophysiological and clinical data on the relationship between nasal diseases and asthma, splitting up three main conditions: allergic rhinitis, chronic rhinosinusitis and nasal polyposis.

    De Poortere, David A; De Poortere, Boris M; Cohen, Noam A

    2012-10-01

    Angiolipoma is a rare, benign variant of lipoma; its distinctive feature is its prominent vascularity. It presents as a subcutaneous nodule of white adipose tissue; pain, which may be exacerbated by pressure, is the chief symptom. The anatomic distribution predominantly involves the trunk and extremities. Because of the rarity of this condition in otorhinolaryngology, our understanding of its diagnosis, treatment, and follow-up is limited. Microscopically, two different histopathologic forms of angiolipomas exist: circumscribed and infiltrating. The diagnosis of angiolipoma can be aided by ultrasound, computed tomography, or magnetic resonance imaging. Surgical excision remains the treatment of choice. Sites of previously reported otolaryngologic cases include the cheek, palate, mandible, nasal septum, and cervical area. We describe what we believe to be the second case of a nasal tip angiolipoma in a 78-year-old woman complaining of progressive aesthetic deformity.

    From Sept 1, 1992 to Dec 31, 1993, 38 outpatient vaginal hysterectomy patients were evaluated for identification of complications after discharge, adequacy of pain relief at home, return to baseline lifestyle, and costs. No complications that would have necessitated an overnight or longer stay were identified. All patients reported adequate pain relief and a more rapid return to activity than they had expected. The hospital cost of outpatient vaginal hysterectomy was about half that of inpatient, and additional significant savings were realized in the cost of postoperative medication. Patients were positive about returning home the day of surgery and would recommend the protocol to others who qualified.

  16. Neuropeptides and nasal secretion.

    PubMed

    Baraniuk, J N; Kaliner, M

    1991-10-01

    The nasal mucosa is innervated by the sensory, parasympathetic, and sympathetic nervous systems. Nociceptive sensory nerves are stimulated by mucosal injury, inhalation of irritants, or mast cell degranulation and release of the calcitonin gene-related peptide, the tachykinins substance P and neurokinin A, and other peptides by the axon response mechanism. Sensory nerve stimulation initiates systemic reflexes, such as the sneeze, and central parasympathetic reflexes which release acetylcholine, vasoactive intestinal peptide, and other peptides and lead to glandular secretion. In concert, these proinflammatory neural responses lead to vasodilation, vascular permeability, and glandular secretion. Sympathetic nerves release neuropeptide Y and norepinephrine, potent vasoconstrictors which act to decompress the nasal mucosa and produce nasal patency. The balance between the effects of parasympathetic and sympathetic neurotransmitters may regulate nasal homeostasis, whereas the nociceptive sensory system may be held in reserve as a defense mechanism. Dysfunction of these systems may lead to pathological nasal syndromes. In the future, specific neuropeptide agonists and antagonists may be useful for the treatment of human rhinitic diseases.

  17. Role of allergy in nasal polyposis: a review.

    PubMed

    Bernstein, J M; Gorfien, J; Noble, B

    1995-12-01

    We propose a multivariate theory for the pathogenesis of nasal polyps. Turbulent flow of air in the lateral wall of the nose or viral-bacterial-host interactions produce an inflammatory change in the mucosa of the lateral wall of the nose. Ulceration and prolapse of the submucosa with reepithelialization and new gland formation may then follow. The structural cells of the nasal polyp, including epithelial cells and fibroblasts, have the ability to produce messenger RNA for granulocyte-monocyte colony-stimulating factor and other cytokines. Stimulation of such an effector capability by structural cell-derived cytokines would undoubtedly represent a major amplification pathway of the inflammatory response in nasal polyps. Allergy may be one mechanism for the development of this cascade of events. This microenvironmental structural inflammatory response in the nasal polyp, in turn, can affect the bioelectric integrity of the Na+ and Cl- channels at the luminal surface of the respiratory epithelial cell. The change in the Na+ absorption, which has been demonstrated in our studies, may result in an increased movement of water into the cell and into the interstitial fluid. The resultant edema can lead to growth and enlargement of the nasal polyp. Finally, the rapid recurrence of nasal polyps despite adequate surgery may reflect some intrinsic phenotypic characteristic of nasal epithelial cells in the lateral wall of the nose, which is likely to be under genetic control.

    PubMed Central

    Pacheco, Ilvia

    2015-01-01

    Background and Objectives: Laparoscopic greater curve plication is emerging as a weight loss procedure that avoids many of the complications of other surgeries that require gastrointestinal division, amputation, or use of a foreign body. Cost savings and affordability have also been promoted, as plication does not require the use of stapling devices, adjustable gastric bands, or prolonged hospitalization. The ability to predictably perform plication as an outpatient surgery may further define its role as a therapeutic option for treating morbid obesity. We present the 30-day outcomes and supplementary 12-month data in a series of 141 laparoscopic greater curve plication surgeries performed as outpatient procedures. Methods: Laparoscopic greater curve plication was performed as outpatient surgery in 141 consecutive patients. Outcomes including perioperative complications, incidental 12-month follow-up for weight loss, and change in diabetic and hypertensive medication are reported. Results: Of the 141 plications performed, 138 patients were discharged from the recovery room and 6 were readmitted. There was no conversion to open surgery and no mortality. Conclusions: The ability to reliably perform greater curve plication as an outpatient surgery may further define its role as an additional weight loss surgery technique. PMID:26508824

    PubMed

    Slütter, Bram; Hagenaars, Niels; Jiskoot, Wim

    2008-01-01

    Nasal vaccination is a promising alternative to classical parental vaccination, as it is non-invasive and, in principle, capable of eliciting strong systemic and local immune responses. However, the protective efficacy of nasally administered antigens is often impaired because of delivery problems: free antigens are readily cleared from the nasal cavity, poorly absorbed by nasal epithelial cells and generally have low intrinsic immunogenicity. In this review paper, we describe the main physiological hurdles to nasal vaccine delivery, survey the progress made in technological approaches to overcome these hurdles and discuss emerging opportunities for improving nasal vaccines. According to current insights, encapsulation of the antigen into bioadhesive (nano)particles is a promising approach towards successful nasal vaccine delivery. These antigen-loaded particles can be tailor made by supplying them with targeting ligands, adjuvants or endosomal escape mediators to form the desired vaccine that provides long-lasting protective immunity.

    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.

    Endoscopic sinus surgery is effective to nasal sinus mucocele with eye symptoms as main manifestation. It is very importment to raise the awareness of the disease and to prompt imaging examination. Three cases were reviewed. One mucocele was found in the frontal sinus ethmoid sinus,1 in the fronto-ethmoid sinus and 1 in the spheno-ethmoid sinus. All cases were preoperatively diagnosed by CT, MRI or intranasal endoscopy. Nasal sinus mucocele with eye symptoms as main manifestation should be early diagnosed. Endoscopic sinus surgery is a safe and effective method for the treatment of nasal sinus mucocele,and could be the primary choice for it. All cases were treated by nasal endoscopic sinus surgery. The majority of symptoms, such as exophthalmos, epiphora and diplopia, disappeared in all patients. However, vision recovery was observed only in some patients.

  7. Surgical Nasal Implants: Indications and Risks.

    2016-10-01

    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. PMID:27680520

    The nasal valve is an important consideration in patients presenting with nasal obstruction. Controversy exists regarding the anatomy, terminology, evaluation, and management of the nasal valve. Innumerable techniques with variable effects have been described in the literature. The evidence qualifying these techniques has been plentiful, though often lacking in quality. This article reviews the controversial aspects of nasal valve management applying the best available evidence to help clarify potential areas of confusion. Future research using standardized definitions, consistent methodologies, and validated outcome measures are necessary to improve the quality of evidence and impact surgical decision-making.

    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. PMID:27437462

    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.

    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.

    Intramuscular haemangioma (IMH) is a benign mesenchymal tumour. It appears as a deep, nontender mass within the soft tissue, particularly in the extremities. This tumour may not be obvious on clinical examination. Head and neck IMHs represent only 13.5% of the total IMHs. The most common site for a head and neck IMH is the masseter muscle, followed by trapezius, sternocleidomastoid, and very rarely temporalis muscle. We present a patient with left nasal bridge swelling which was excised and histologically confirmed as intramuscular hemangioma. PMID:25709848

    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.

  15. The effects of naris occlusion on mouse nasal turbinate development.

    PubMed

    2014-06-15

    Unilateral naris occlusion, a standard method for causing odor deprivation, also alters airflow on both sides of the nasal cavity. We reasoned that manipulating airflow by occlusion could affect nasal turbinate development given the ubiquitous role of environmental stimuli in ontogenesis. To test this hypothesis, newborn mice received unilateral occlusion or sham surgery and were allowed to reach adulthood. Morphological measurements were then made of paraffin sections of the whole nasal cavity. Occlusion significantly affected the size, shape and position of turbinates. In particular, the nasoturbinate, the focus of our quantitative analysis, had a more delicate appearance on the occluded side relative to the open side. Occlusion also caused an increase in the width of the dorsal meatus within the non-occluded and occluded nasal fossae, compared with controls, and the position of most turbinates was altered. These results suggest that a mechanical stimulus from respiratory airflow is necessary for the normal morphological development of turbinates. To explore this idea, we estimated the mechanical forces on turbinates caused by airflow during normal respiration that would be absent as a result of occlusion. Magnetic resonance imaging scans were used to construct a three-dimensional model of the mouse nasal cavity that provided the input for a computational fluid dynamics simulation of nasal airflow. The simulation revealed maximum shear stress values for the walls of turbinates in the 1 Pa range, a magnitude that causes remodeling in other biological tissues. These observations raise the intriguing possibility that nasal turbinates develop partly under the control of respiratory mechanical forces.

    Severe atrophy of the anterior maxilla represents a major challenge for the clinician when planning an implant-supported rehabilitation. Several surgical options are available for augmenting bone volume in this area, including onlay or interpositional bone grafts, guided bone regeneration, distraction osteogenesis, and nasal floor augmentation. This case report describes a novel approach to nasal floor elevation using ultrasonic instruments to prepare the implant sites followed by transcrestal hydrodynamic nasal mucosa elevation and grafting with a collagenized xenogeneic biomaterial. This minimally invasive technique allowed for vertical augmentation of the atrophic anterior maxilla together with implant placement in a single-stage surgery. PMID:27100805

    We report a case of keratoacanthoma in a non-sun-exposed nasal vestibule of an 84-year-old man. He presented with a progressively growing left nasal mass that had been present for 8 months. Examination showed a non-tender protruding mass arising from medial vestibular wall of the left nostril. Histopathology indicated it was a keratoacanthoma. In an elderly patient with a history of a progressively growing mass in the nose, a differential diagnosis of malignancy should be ruled out, and histological conformation is essential. To our knowledge, only a very small number of cases of nasal vestibular keratoacanthoma have been reported. PMID:24376301

    The nasal valve has long been described as the anatomical boundary most likely to inhibit nasal airflow and lead to subsequent nasal obstruction. Although many procedures can address this area to improve the nasal airway, for over 20 years, suture lateralization of the external nasal valve has been described as a minimally invasive technique that can improve nasal breathing. We report our modification of the standard technique in which we lateralize the placement of the bone-anchored suture and incorporate Gore-Tex within the nasal vestibular incision to prevent tissue migration.

    The purpose of this study was to investigate the effect of thiolated polycarbophil as an adjuvant to enhance the permeation and improve the stability of a phosphorothioate antisense oligonucleotide (PTO-ODN) on the nasal mucosa. Polycarbophil-cysteine (PCP-Cys) was synthesized by the covalent attachment of L-cysteine to the polymeric backbone. Cytotoxicity tests were examined on human nasal epithelial cells from surgery of nasal polyps confirmed by histological studies. Deoxyribonuclease I activity in respiratory region of the porcine nasal cavity was analyzed by an enzymatic assay. The enzymatic degradation of PTO-ODNs on freshly excised porcine nasal mucosa was analyzed and protection of PCP-cysteine toward DNase I degradation was evaluated. Permeation studies were performed in Ussing-type diffusion chambers. PCP-Cys/GSH did not arise a remarkable mortal effect. Porcine respiratory mucosa was shown to possess nuclease activity corresponding to 0.69 Kunitz units/mL. PTO-ODNs were degraded by incubation with nasal mucosa. In the presence of 0.45% thiolated polycarbophil and 0.5% glutathione (GSH), this degradation process could be lowered. In the presence of thiolated polycarbophil and GSH the uptake of PTO-ODNs from the nasal mucosa was 1.7-fold improved. According to these results thiolated polycarbophil/GSH might be a promising excipient for nasal administration of PTO-ODNs.

    2016-01-01

    Background: The importance of analysis of the nasal spine should not be underestimated in the correct planning of rhinoplasty. Deformations in position with respect to the midline and/or in size are often present, and their correction to ensure harmony between the spine and the other components of the nasal pyramid constitutes a key step in rhinoplasty that can lead to excellent results. Methods: The study includes 160 patients who underwent surgical treatment of the anterior nasal spine with or without other techniques of nasal reshaping. Eighty-seven of these patients presented with hyperplasia of the nasal spine, 43 with hypoplasia, and 30 with deviation. A combination of deviation and hyperplasia was present in 15 cases. Results: No patients developed postoperative complications. Five patients who underwent anterior nasal spine reduction reported postoperative numbness in the premaxillary area, but sensitivity was fully regained within 4 months after surgery in these patients. All the patients reported postoperative improvement of nasal airflow. A total of 142 patients considered their postoperative aesthetic result as excellent and 18 as good. Conclusion: The simplicity of the surgical procedures performed on the nasal spine and the marked aesthetic improvements thus achieved suggest that greater attention should be paid to this anatomical region.

    The ability of the human nose to warm and humidify the respiratory air is important to maintaining the internal environment of the lungs, since ambient air is conditioned to nearly alveolar conditions (body temperature and fully saturated with water vapour) upon reaching the nasopharynx. Because of very short time of the inspiratory phase duration, as well as expiratory phase, only the rich vascularization of the nasal mucosa and specific organization of the submucosal vessels are not able to assure such effective physiological activity. Therefore the type of airflow during the respiration is essential to understanding the functional possibilities of the nasal mucosa. Most studies have investigated the airflow only in steady-flow conditions, where the laminar flow was observed. Anatomically accurate physical models of real nasal cavities and particle image velocimetry allow evaluation of the entire flow field in the nasal cavity. In these investigations a partially turbulent flow was observed even at low air velocities in most part of the nasal cavity. From a physiological perspective, a turbulent flow would seem sensible, since it enhances contact between air and the mucosal layer. By doing so, the nasal physiological functions - humidification, cleaning and warming are optimized.

    2013-01-01

    Background: Chronic rhinosinusitis (CRS) is one of the most common chronic medical conditions, with a significant impact on patient quality of life. CRS is broadly classified into two groups: CRS with nasal polyposis (CRSwNP) and CRS without NP (CRSsNP). Clinically, the major subtypes of CRSwNP may be divided into eosinophilic chronic rhinosinusitis (e.g., allergic fungal rhinosinusitis and aspirin-exacerbated respiratory disease [AERD]) and nasal polyps associated with neutrophilic inflammation (e.g., cystic fibrosis [CF]). CF is characterized by mutation of the gene encoding the CF transmembrane conductance regulator. Functional endoscopic sinus surgery is usually required for most NP patients with increased frequency in patients with AERD. This study provides a review of the epidemiology and major classification of CRSwNP. Methods: A review was performed of the literature regarding different subtypes of CRSwNP. Results: Many definitions of CRSwNP exist and estimates of prevalence vary. Conclusion: CRSwNP is a clinical syndrome with a heterogeneous inflammatory profile. Of the subtypes associated with eosinophilic inflammation, AERD remains the most recalcitrant to medical and surgical therapeutic interventions. PMID:24274222

    A sphenochoanal polyp is a rare lesion that originates in the sphenoid sinus. It occurs most often in adolescents and young adults. We present what to the best of our knowledge is the first reported case of a sphenochoanal polyp associated with concomitant nasal polyps. The patient was a 54-year-old man who presented with bilateral nasal obstruction, possible obstructive sleep apnea, and an altered voice, all of which had likely been caused by the presence of a massive left sphenochoanal polyp and bilateral grade III anterior and posterior ethmoid polyps. Because the patient had dilated cardiomyopathy, he was not a good candidate for general anesthesia. Therefore, the polyps were removed endoscopically under local anesthesia. The sphenochoanal polyp measured 7.5 cm in its greatest dimension and weighed 41 g. The patient remained symptom-free at the 1-year follow-up. The presentation of a sphenochoanal polyp is similar to that of the more common antrochoanal polyp, but the two can usually be differentiated on computed tomography. Endoscopic sinus surgery allows for complete removal of the polyp, including its site of origin, which minimizes the risk of recurrence.

    2016-01-01

    Background: Epistaxis is a common problem in childhood. It has been shown that children with recurrent epistaxis are more likely to have nasal colonization with Staphylococcus aureus. It has been suggested that low-grade inflammation, crusting and increased vascularity due to bacterial colonization contributes to the development of epistaxis in children. Aims: This study aimed to investigate the nasal colonization and treatment outcome in pediatric epistaxis patients. Study Design: Retrospective cross-sectional study. Methods: Charts of the pediatric patients referred to our university hospital otolaryngology outpatient clinics for the evaluation of epistaxis were reviewed. The patients whose nasal cultures had been taken at the first clinical visit comprised the study group. Results: Staphylococcus aureus was the most common bacteria grown. The presence of crusting and hypervascularity was not dependent on the type of bacterial growth and there was no relation between hypervascularity and crusting of the nasal mucosa. Thirty-six patients were evaluated for the outcome analysis. Resolution of bleeding was not dependent on nasal colonization; in patients with colonization, there was no difference between topical antibacterial and non-antibacterial treatments. Conclusion: Despite the high colonization rates, topical antibacterial treatment was not found superior to non-antibacterial treatment. Our study does not support the belief that bacterial colonization results in hypervascularity of the septal mucosa causing epistaxis since no relation was found between nasal colonization, hypervascularity and crusting. The role of bacterial colonization in pediatric epistaxis need to be further investigated and treatment protocols must be determined accordingly. PMID:27403392

    Introduction Vascular leiomyoma of the nasal cavity is an extremely rare tumor that represents less than 1% of all vascular leiomyomas. It is more prevalent in women between the fourth and sixth decades, reaching primarily the inferior nasal turbinates. Objectives Reporting and assisting the systematization of more accurate diagnostic methods in clinical and complementary investigation of vascular leiomyoma in the nasal cavity. Resumed Report We present the case of a 49-year-old woman diagnosed with vascular leiomyoma in the nasal cavity, which manifested mainly with nasal obstruction. During investigation, computer tomography was not diagnostic, the cytologic study was not conclusive, and according to the biopsy, it was a squamous papilloma. Conclusion We suggest that the technical difficulty in obtaining an adequate amount of material for preoperative biopsy, associated with the topography of the lesion in the vestibular nasal region, may have contributed to changing the postoperative diagnosis. Thus, pathologic study of the surgical fragment is the more accurate method for diagnosis. PMID:25992133

    Summary Introduction: Extramedullary plasmacytoma is a plasma cell tumor that grows within any of the soft tissues of the organism. Similar to all plasmacytic dyscrasia, the disease is extremely rare. Aim: This study reports a case of an extramedullary plasmacytoma of the nasal cavity and provides a literature review on the topic. Case report: A 51-year-old woman presented at our tertiary university hospital with a 6-month history of progressive nasal obstruction, predominantly to the right side, and self-limiting epistaxis. Examination revealed a large pale-reddish tumor within the right nasal cavity. Anatomopathological analysis showed features consistent with a plasmacytoma diagnosis, which was subsequently confirmed by immunohistochemical techniques. Further assessment revealed the solitary nature of the condition, consistent with extramedullary plasmacytoma. Radiotherapy was initiated, which led to partial regression of the symptoms. The tumor was surgically removed by using a mid-facial degloving approach. The patient evolved with a naso-oral fistula and underwent 3 corrective surgeries. No evidence of associated systemic disease was found after 5 years of follow-up. Conclusions: This case report, which describes a rare tumor of the nasal cavity, is expected to improve the recognition and referral of this condition by ear, nose, and throat (ENT) specialists for multidisciplinary management and long-term follow-up.

    nasal trauma which was not treated on time or it was improperly treated. In 24 (58.54%) of these patients septoplasty was performed and in 17 (41.46%) was performed rhino septoplasty. CONCLUSION: Often, difficult septal deformations in children are followed with deformation of the nasal pyramid (rhino scoliosis, rhino lordosis). In those cases, we cannot solve septal pathology without nasal pyramid intervention in the same time and opposite. Clinical reports have not produced solid evidence for the statement that septal surgery has no negative effect on nasal growth or can serve for correcting abnormal growth.

    Profile alignment, including nasal dorsal reduction, is one of the most common maneuvers in aesthetic rhinoplasty. Techniques often include cartilaginous excision and bony hump reduction with a chisel or a rasp. Cartilaginous nasal vault excision can result in separation of the junction between the upper lateral cartilages and the dorsal septum. This separation can cause an inferior-medial repositioning of the upper lateral cartilages and overall weakening of middle vault infrastructure. Furthermore, surgical interruption of this key region can also damage the internal nasal valve configuration and function and create static and dynamic airway obstruction. This article outlines the anatomy and function of the middle nasal vault and internal nasal valve. In addition, it provides an overview of aesthetic complications of dorsal hump removal including inverted-V deformity, saddle nose deformity, hourglass deformity, and their functional consequences. Preoperative individual risk factors for middle-third deformities are mentioned. Preventive and corrective surgical techniques including cartilage grafting and reconstructive sutures are also detailed.

    Rhinoplasty is one of the most complicated aesthetic surgeries. One important factor in nasal profile analysis before surgery is the NTP (Nasal Tip Projection). There has been controversy over defining the best tip projection and due to cultural differences there is a need to find the best formulation for Iranian noses. We selected 50 randomized patients. Lateral nasal views were captured from all of the patients. In order to equalize the photos, all tip rotations changed first to 105. We selected four methods for measuring NTP (Goode, Crumley 1, Crumley 2, and Powell and Humphreys). Based on these methods NTP was shown in four pictures. A questionnaire was designed for rating the pictures. Questionnaires were filled in by 3 different groups: rhinoplasty surgeons, general people, and artists. A total of 73 questionnaires were filled in. The analysis and comparison were done. Crumley 2 is the best NTP measurement method from the surgeons' and artists' view. Goode is the method preferred by general people. Powell & Humphreys method seems to be the worst method from all 3 groups' view. It seems that general people prefer smaller noses, because projection in Goode method is almost less than Crumley 2. PMID:27293886

    In E.N.T clinical practice, patients with nasal obstruction due to deviated nasal septum is a common presentation. Nasal airway obstruction is a common cause of upper airway obstruction further leading to obstructive and hypoxic manifestations. Mean platelet volume (MPV) levels increase in hypoxic conditions. MPV is one of the platelet activation index which reflects the platelet production rate. Present prospective study conducted in the department of Otorhinolaryngology and Head and Neck surgery, Gandhi Medical College and Hamidia Hospital, Bhopal, on 63 patients with the clinical evidence of DNS and 63 healthy age matched subjects as control group, aimed to evaluate the relationship between MPV levels and nasal obstruction due to deviated nasal septum (DNS). The diagnosis of patients with DNS was based on anterior rhinoscopy and endoscopic nasal examination. Blood samples were collected before surgical correction. In present study, the authors found that there is preponderance of DNS in the age group of 25-45 years being the most active age group, males having the higher incidence. Majority of cases of DNS being left sided and of obstructed type. MPV were significantly higher in patients with DNS than the control group. Among the cases MPV being higher in females and in the impacted type of DNS. Present study reemphasized the concept that MPV is increased in chronic nasal obstruction due to DNS and this increase is in accordance with the severity of DNS.

    The computational fluid dynamics (CFD) are used to evaluate the physiological function of the nose. We evaluated the aerodynamics of the nasal cavity in a patient with septal perforation (SP), pre- and postvirtual repair. Three-dimensional nasal models were reconstructed, and then a wide range of the pressure drops and flow rates were analyzed. The airflow velocity is higher in the central region and is lower around the boundary of the SP. The air velocity in the SP increases as the pressure drop increases. Furthermore, at the anterior part of the SP, the shear stress is higher in the upper part. In addition, the repair of SP does not affect the total nasal airflow rate and the velocity contour patterns. The potential usage of the CFD technique as a predictive technique to explore the details and a preoperative assessment tool to help in clinical decision making in nasal surgery is emphasized.

    The forehead flap is a commonly used technique to reconstruct the deep and large nasal defects. It can be conveniently performed under local or general anesthesia and provides a very good color and texture matching to the nasal skin, which makes it a suitable graft harvesting site for nasal reconstruction. It has only single disadvantage disadvantagethat it is a two-stage procedure and “finishing” surgeries are needed occasionally for best surgical and cosmetic outcome. In this paper, we describe three different applications of forehead flaps. PMID:26668457

    Summary: Reconstructing the 3-dimensional structure of the nose requires the maintenance of its aesthetic form and function. Restoration of the correct dimension, projection, skin quality, symmetrical contour, and function remains problematic. Consequently, modern approaches of nasal reconstruction aim at rebuilding the units rather than just covering the defect. However, revising or redoing a failed or insufficient reconstruction remains very challenging and requires experience and creativity. Here, we present a very particular case with a male patient, who underwent 37 operations elsewhere and presented with a failed nasal reconstruction. We describe and illustrate the complex steps of the nasal rereconstruction, including the reconstruction of the forehead donor site, surgical delay procedures for lining, and the coverage with a third paramedian forehead flap.

    Due to the prominent location of the nose, the most common facial traumas are nasal injuries. Although nasal traumas usually require staged intervention at a later period of time, in selected cases, primary reconstruction can be effective. A 20-year-old man who was referred from the emergency department with nasal trauma is presented. He reported a fall after feeling unsteady, which caused a direct nasal injury. Clinical examination revealed septal fracture with obstruction of the left nasal cavity and deformity of the nasal pyramid (inverted V deformity). The patient also had a complete dissection of the columella skin. Epistaxis was self-limited, and an open rhinoplasty procedure was decided because the trauma occurred 1 h before admission and there was no significant edema. Surgical intervention included septal reconstruction combined with restoration of the nasal pyramid and columella. One month later, the patient had patent nasal airways, and he was satisfied with the aesthetic result. PMID:22942663

    The objective of the current study was to analyze the effects of rhinoseptoplasty on internal nasal dimensions and speech resonance of individuals with unilateral cleft lip and palate, estimated by acoustic rhinometry and nasometry, respectively. Twenty-one individuals (aged 15-46 years) with previously repaired unilateral cleft lip and palate were analyzed before (PRE), and 6 to 9 (POST1) and 12 to 18 months (POST2) after surgery. Acoustic rhinometry was used to measure the cross-sectional areas (CSAs) of segments corresponding to the nasal valve (CSA1), anterior portion (CSA2), and posterior portion (CSA3) of the lower turbinate, and the volumes at the nasal valve (V1) and turbinate (V2) regions at cleft and noncleft sides, before and after nasal decongestion with a topical vasoconstrictor. Nasometry was used to evaluate speech nasalance during the reading of a set of sentences containing nasal sounds and other devoid of nasal sounds. At the cleft side, before nasal decongestion, there was a significant increase (P < 0.05) in mean CSA1 and V1 values at POST1 and POST2 compared with PRE. After decongestion, increased values were also observed for CSA2 and V2 at POST2. No significant changes were observed at the noncleft side. Mean nasalance values at PRE, POST1, and POST2 were not different from each other in both oral and nasal sentences. The measurement of CSAs and volumes by acoustic rhinometry revealed that rhinoseptoplasty provided, in most cases analyzed, a significant increase in nasal patency, without concomitant changes in speech resonance, as estimated by nasalance assessment.

    Introduction: Chronic sinusitis with nasal polyps is one of the commonest diseases of the upper airways, with a recurrence rate of about 15%. Minimally-invasive endoscopic laser procedures have been established to reduce the need for conventional revision surgery whenever medical follow-up fails. However, laser surgery requires special considerations for surgical, safety and economic aspects. This study evaluates the feasibility of coblation versus laser resection for recurrent nasal polyps. Material and methods: 6 nasal polyps were harvested each from the ostiomeatal complex of patients undergoing microscopic endonasal surgery for chronic sinusitis. 3 were dissected using a Neodymium:YAG laser system (Dornier MediLas 5060N) set at 10, 20 and 30w in cw mode with a 600μm bare fiber in contact mode with negative feedback power control, while further 3 polyps were dissected using a Coblation system (ArthroCare® Coblator® I) with a 30° angled and a 0° straight probe with 2.4 mm outer diameter. The specimens were examined histologically for carbonization and coagulation as well as unaltered tissue. Results: Laser resection resulted in a carbonization zone of 30μm in depth plus a coagulation zone of about 100μm, depending on the water content and type of tissue. While the carbonization zone was smaller with coblation, coagulation zones were comparable, leaving ample amount of unaltered tissue available for further diagnosis. Conclusion: Both resection techniques are generally feasible to be used in day case surgery for recurrent polyps. While the coblation system required no special safety requirements, accessibility of the sinuses was limited by the rigidity of applicators that are available.

A 75 year-old female with optic nerve head damage secondary to chronic open angle glaucoma developed macular schisis and a separate area of retinoschisis nasal to her optic disk. There were no other identifiable causes for her retinoschisis. Glaucoma related structural defects offer a plausible explanation for multiple cavities of retinoschisis in favor of multiple occult congenital pits of the optic nerve head. PMID:20337311

    This is a report on a pilot study conducted in Malaysia of outpatient sterilization utilizing laparoscopic technique under local anesthesia and sedation. The preliminary report based on 305 patients is presented with emphasis on the advantages and possible weaknesses of such procedure. Sterilization is performed in the Family Planning Specialist Center, Maternity Hospital. Patients are motivated towards sterilization during the immediate postpartum period in the Maternity Hospital and are counseled regarding the actual procedure. The mean age of the 305 patients was 32.08 years; the mean gravidity was 4.92; and the mean parity was 4.57. The majority of the patients came from the lower social strata with low educational attainment and low income. 253 cases of sterilizations were performed by laparoscopic procedures and 43 cases by minilaparotomy. In 9 cases difficulty was encountered with laparoscopy and subsequently the minilaparotomy was used. The majority of cases seemed to tolerate the sedation and local anesthesia fairly well and without much complaint of pain. Only a very small number of patients complained of pain particularly at the time when the Fallope or Lay rings were applied to the fallopian tubes. The overall complication rate was 14 (4.9%) and of these mild wound sepsis accounted for 6 (1.96%). Most of the wound sepsis was very mild and healed very quickly on daily dressing. No cases of pelvic sepsis were reported. There were 3 cases of uterine perforation by the uterine elevator. There were 2 cases where the fallopian tubes were traumatized and some degree of bleeding occurred. The bleeding was easily controlled by applying another Fallope ring. 2 patients had vomiting during the laparoscopic procedure. There were 7 cases of failed sterilization. 6 of the cases were performed by a trainee registrar in obstetrics and gynecology. The last was performed by a specialist gynecologist. Most of the failures were due to wrong application of rings. The cost

    The use of prosthetic devices for correction of velopharyngeal insufficiency (VPI) is an alternative treatment for patients with conditions that preclude surgery and for those individuals with a hypofunctional velopharynx (HV) with a poor prognosis for the surgical repair of VPI. Understanding the role and measuring the outcome of prosthetic treatment of velopharyngeal dysfunction requires the use of tools that allow for documenting pre- and post-treatment outcomes. Experimental openings in speech bulbs have been used for simulating VPI in studies documenting changes in aerodynamic, acoustic and kinematics aspects of speech associated with the use of palatal prosthetic devices. The use of nasometry to document changes in speech associated with experimental openings in speech bulbs, however, has not been described in the literature. Objective This single-subject study investigated nasalance and nasality at the presence of experimental openings drilled through the speech bulb of a patient with HV. Material and Methods Nasometric recordings of the word "pato" were obtained under 4 velopharyngeal conditions: no-opening (control condition), no speech bulb, speech bulb with a 20 mm2 opening, and speech bulb with 30 mm2 opening. Five speech-language pathologists performed auditory-perceptual ratings while the subject read an oral passage under all conditions. Results Kruskal-Wallis test showed significant difference among conditions (p=0.0002), with Scheffé post hoc test indicating difference from the no-opening condition. Conclusion The changes in nasalance observed after drilling holes of known sizes in a speech bulb suggest that nasometry reflect changes in transfer of sound energy related to different sizes of velopharyngeal opening.

    The objective of this study was to investigate the relationship between in vitro permeability (Papp) values obtained from isolated nasal tissues and the absorption rates (ka) of the same compounds following nasal administration in animals and humans. The Papp of a set of 11 drug compounds was measured using animal nasal explants and plasma time-concentration profiles for each of the same compounds following intravenous (IV) and intranasal (IN) administration were experimentally determined or obtained from literature reports. The plasma clearance was estimated from the IV plasma time-concentration profiles, and ka was determined from the IN plasma time-concentration profiles using a deconvolution approach. The level of correlation between Papp and ka was established using Pearson correlation analysis. A good correlation (r=0.77) representing a point-to-point relationship for each of the compounds was observed. This result indicates that the nasal absorption for many drug candidates can be estimated from a readily measured in vitro Papp value. PMID:23225081

    In all rhinoplasty surgery, the universal need exists to increase, decrease, or preserve existing tip projection. When proper tip projection is lacking, a variety of techniques are useful for improving projection. We describe a valuable technique for tip projection, particularly useful and indicated in the Asian rhinoplasty, African American rhinoplasty, and in certain revision rhinoplasties. In the past 15 years, the senior author (M.E.T.) has used the contoured auricular projection graft in selected patients for achieving satisfactory tip projection in patients with blunted tips. The aesthetic outcomes have been predictable, pleasing, and reliable for the long term. Precision pocket preparation for auricular conchal cartilage graft placement is key to symmetry and projection of the final outcome. The results yielded a rounded nasal tip that may be more natural-appearing in Asians, African Americans, and selected patients with revision rhinoplasty. The contoured auricular projection graft provides a highly useful graft for the nasal tip. PMID:10937122

    Pneumocephalus is collection of gas or air within the cranial cavity, commonly associated with trauma, cranial surgery, air embolism, open meningomyelocele; and rarely as a result of central nervous system infections. Asymptomatic pneumocephalus usually recovers spontaneously within few days. Untreated pneumocephalus can progress to tension pneumocephalus, manifesting as severe headache, dizziness, cranial nerve palsy, mental changes, seizure and disorientation. Herein, we report a rare case of pneumocephalus in a 9-month infant with subdural effusion following infection of nasal septum and otomastoiditis. There was no sign of meningitis but CThead showed communication of intracranial dura mater across widened foramen caecum with pre-nasal space, and bilateral otomastoiditis with erosion of anterior and lateral wall of right mastoid bone. The patient was treated successfully and discharged without sequelae. PMID:27504559

    The posterior nasal nerve is the dominant source of the parasympathetic, sympathetic, and sensory fibers that innervate the nasal respiratory mucosa. Therefore, a posterior nasal neurectomy (PNN) is thought to induce denervation of the nasal mucosa and relieve the nasal symptoms of allergic rhinitis. However, the underlying mechanisms and therapeutic action of PNN remain unknown. To investigate the impact of PNN-induced denervation of the nasal mucosa on allergic rhinitis, we developed a rat model of PNN and examined the effects of PNN on allergic rhinitis in ovalbumin-sensitized rats. This rat model of PNN was characterized by the depletion of nerve fibers, choline acetyltransferase, and neuropeptides (eg, substance P, calcitonin gene-related peptide, vasoactive intestinal peptide, and neuropeptide Y) in the nasal respiratory mucosa. These animals exhibited nasal gland and goblet cell hypertrophy in the septal mucosa and atrophy of the submucosal gland in the lateral nasal wall, as well as reduced nasal secretion due to deficient acetylcholine synthesis. In an ovalbumin-sensitized model of allergic rhinitis, PNN also induced the depletion of nerve fibers, choline acetyltransferase, and neuropeptides in the nasal mucosa and suppressed nasal secretion. However, PNN did not affect mucosal thickening, eosinophil and mast cell infiltration, interleukin-4 and interferon-γ mRNA expression, and allergic symptoms (ie, sneezing and nasal scratching). These results suggest that the peripheral nerves and corresponding neuropeptides regulate nasal secretion, but not hypersensitivity, in allergic rhinitis, and that allergic rhinitis-related mucosal reactions occur in a highly denervated mucosa after PNN. Posterior nasal neurectomy may be a therapeutic option for the treatment of hyperrhinorrhea, but not allergic rhinitis hypersensitivity. PMID:27322954

    Each year, health care costs for managing chronically ill patients increase as the life expectancy of Americans continues to grow. To handle this situation, many hospitals, doctors practices, and home care providers are turning to disease management, a system of coordinated health care interventions and communications, to improve outpatient care. By participating in daily monitoring programs, patients with congestive heart failure, chronic obstructive pulmonary disease, diabetes, and other chronic conditions requiring significant self-care are facing fewer emergency situations and hospitalizations. Cybernet Medical, a division of Ann Arbor, Michigan-based Cybernet Systems Corporation, is using the latest communications technology to augment the ways health care professionals monitor and assess patients with chronic diseases, while at the same time simplifying the patients interaction with technology. Cybernet s newest commercial product for this purpose evolved from research funded by NASA, the National Institute of Mental Health, and the Advanced Research Projects Agency. The research focused on the physiological assessment of astronauts and soldiers, human performance evaluation, and human-computer interaction. Cybernet Medical's MedStar Disease Management Data Collection System is an affordable, widely deployable solution for improving in-home-patient chronic disease management. The system's battery-powered and portable interface device collects physiological data from off-the-shelf instruments.

    The objective was to evaluate the magnitude of various contributors to outpatient commercial colonoscopy prices, including market- and provider-level factors, especially market share. We used adjudicated fee-for-service facility claims from a large commercial insurer for colonoscopies occurring in hospital outpatient department or ambulatory surgery center from October 2005 to December 2012. Claims were matched to provider- and market-level data. Linear fixed effects regressions of negotiated colonoscopy price were run on provider, system, and market characteristics. Markets were defined as counties. There were 178,433 claims from 169 providers (104 systems). The mean system market share was 76% (SD = 0.34) and the mean real (deflated) price was US$1363 (SD = 374), ranging from US$169 to US$2748. For every percentage point increase in a system or individual facility's bed share, relative price increased by 2 to 4 percentage points; this result was stable across a number of specifications. Market population and price were also consistently positively related, though this relation was small in magnitude. No other factor explained price as strongly as market share. Price variation for colonoscopy was driven primarily by market share, of particular concern as the number of mergers increases in wake of the recession and the Affordable Care Act. Whether variation is justified by better quality care requires further research to determine whether quality is subsumed in prices.

    The structures of the nose are arguably the most complex within the face to reconstitute when absent. Total nasal reconstruction has evolved to encompass advanced surgical techniques in an effort to achieve increasingly satisfactory cosmetic results while restoring nasal function that mimics the function of a patient's natural nose. In this article, the history of total nasal defects and their reconstruction, relevant nasal anatomy, etiologies of the defect, and the surgical approaches to reconstructing each of the three-layered structure of the nose (ie, nasal skin, cartilage/bone, and lining mucosa) are explored.

    The cause of nasal polyp formation is still unknown. Genetic predisposition has been suggested, but there are scanty data to support such theories. Activated epithelial cells may be the major source of mediators inducing influx of inflammatory cells (mostly eosinophils) and proliferation and activation of fibroblasts leading to nasal polyp formation. Infectious agents (including viruses, bacteria, or fungi) may be potential primary factors activating nasal epithelial cells. Proinflammatory cytokines and growth factors play important roles in the persistence of mucosal inflammation associated with nasal polyps. Arachidonic acid metabolites seem to be particularly important in the pathogenesis of nasal polyps in patients with aspirin hypersensitivity rhinosinusitis/asthma syndrome. PMID:16216171

    To evaluate the cytology of nasal mucosa and sense of smell and nasal patency in patients underwent carbon dioxide laser turbinoplasty (CO2 laser mucotomy) due to chronic nasal hypertrophy. 46 patients with inferior turbinate hypertrophy underwent complete laryngological examination, anterior rhinomanometry, olfactory measurements and cytology of nasal mucous which were performed before and 3 months after CO2 laser mucotomy. Laser mucotomy was performed under local anesthesia. Cytograms revealed significant changes in cell proportion before and after the surgery. Goblet cells predominated in nasal smears before the laser mucotomy. An average percentage of eosinophils in evaluated cytograms before the surgery was 2.1%. Three months after laser mucotomy we observed decrease in goblet cells proportion (the mean range of goblet cells was 16.4%) in nasal cytology. We have also observed improvement in olfactory function, however only in 7 patients (20.6%). The mean value of total nasal airway resistance (NAR) before treatment was 0.98+/-0.24 Pa/cm3/s at 75 Pa. Rhinomanometry after 3 months showed a reduction in mean total resistance from the pretreatment level to 0.77 Pa/cm3/s. We believe that CO2 laser mucotomy is an efficacious, minimally invasive and easy to use treatment of inferior turbinate hypertrophy which is performed under local anesthesia with little discomfort for the patient and does not require hospitalization.

In particular, English speakers produce confusable, or ``hard'' words with more nasal and vowel-to-vowel coarticulation than less confusable, ``easy'' ones. Thus, it has been suggested that speakers produce additional coarticulation in order to increase the intelligibility of ``hard'' words. Here, the relation between nasal coarticulation and lexical confusability is investigated for French, a language in which vowel nasality is phonemically contrastive (at least for a subset of vowels) and might constrain such a lexical effect. Acoustic measures of nasality show that ``hard'' words (those with low usage frequencies and many frequent, phonologically similar neighbors) exhibit more nasal coarticulation than ``easy'' ones (those with high frequencies and few, low-frequency neighbors) in French as well. Interestingly, however, the effect emerges only for words containing vowels that can exhibit phonemic oral-nasal contrasts (oral vowels with nasal counterparts). Thus, where the use of nasality in phonological contrast is constrained, coarticulatory nasality is constrained, too. But the existence of phonological contrast does not itself constrain the lexical confusability effect: increased coarticulatory nasality contributes to lexically motivated phonetic enhancement in French, while even more nasality provides the basis for phonemic contrast.

    Self-inflicted injury of the nose is extremely rare. It may be associated with severe psychopathology and suicidal ideation. The authors report a case of a 24-year-old man, who presented with soft-tissue loss over both the alae of his nose. He had cut off the alar rims with an ordinary razor blade. He was overtly concerned about his nose being excessively broad and fat. A diagnosis of body dysmorphic disorder with nonsuicidal self-injury was made. Patient was observed during 72 hours in hospital with psychiatric support and local dressings. The authors undertook primary nasal reconstruction with nasolabial flaps on both sides for coverage. In conclusion, self-inflicted nasal injury mandates a judicious balancing of psychiatric support and surgical reconstruction. This can prevent untoward sequelae including further self-harm and suicide.

    Negative upper airway pressure is thought to play a key role in the pathophysiology of obstructive sleep apnea. Because nasal resistance contributes to the increase of the transpharyngeal pressure gradient, we evaluated the effects of nasal surgery on sleep-related breathing abnormalities in 20 adults with obstructive sleep apnea. Polysomnographic studies were done before (baseline), and 2 to 3 mo after surgery (septoplasty, turbinectomy, and/or polypectomy). Nasal resistances were measured at these visits in 14 patients. Cephalometric measurements were obtained before surgery. Cephalometric abnormalities consisted in an increase in the distance from the mandibular plane to the hyoid bone (MP-H), a decrease in the space between the base of the tongue and the posterior soft tissues (PAS), a retroposition of the mandibule, and an increase in the length of the soft palate. Body weight did not change between the two studies. Nasal resistance decreased significantly after nasal surgery. The composition of the total sleep time spent in the rapid eye movement stage increased from 11.5 +/- 1.3% (mean +/- SEM) to 14 +/- 1.2% after surgery. For the group as the whole, there was no difference between baseline and postsurgical values in the frequency of respiratory disturbances (39.8 +/- 6.1, 36.8 +/- 5.9 n/h), the total apnea time (17.8 +/- 4.2, 15.4 +/- 2.8), the distribution of the apnea time within the different apnea types (obstructive and nonobstructive), and the severity of the nocturnal desaturations. Interestingly, apnea and apnea plus hypopnea indices returned to normal values (< 5 and 10, respectively) in four subjects with normal posterior soft tissues and mandibular plane to the hyoid bone distances.(ABSTRACT TRUNCATED AT 250 WORDS)

    Objectives Chronic rhinosinusitis (CRS) is a common chronic disease of the upper airways and has considerable impact on quality of life. Topical delivery of drugs to the paranasal sinuses is challenging, therefore the rate of surgery is high. This study investigates the delivery efficiency of a pulsating aerosol in comparison to a nasal pump spray to the sinuses and the nose in healthy volunteers and in CRS patients before and after sinus surgery. Methods 99mTc-DTPA pulsating aerosols were applied in eleven CRSsNP patients without nasal polyps before and after sinus surgery. In addition, pulsating aerosols were studied in comparison to nasal pump sprays in eleven healthy volunteers. Total nasal and frontal, maxillary and sphenoidal sinus aerosol deposition and lung penetration were assessed by anterior and lateral planar gamma camera imaging. Results In healthy volunteers nasal pump sprays resulted in 100% nasal, non-significant sinus and lung deposition, while pulsating aerosols resulted 61.3+/-8.6% nasal deposition and 38.7% exit the other nostril. 9.7+/-2.0 % of the nasal dose penetrated into maxillary and sphenoidal sinuses. In CRS patients, total nasal deposition was 56.7+/-13.3% and 46.7+/-12.7% before and after sinus surgery, respectively (p<0.01). Accordingly, maxillary and sphenoidal sinus deposition was 4.8+/-2.2% and 8.2+/-3.8% of the nasal dose (p<0.01). Neither in healthy volunteers nor in CRS patients there was significant dose in the frontal sinuses. Conclusion In contrast to nasal pump sprays, pulsating aerosols can deliver significant doses into posterior nasal spaces and paranasal sinuses, providing alternative therapy options before and after sinus surgery. Patients with chronic lung diseases based on clearance dysfunction may also benefit from pulsating aerosols, since these diseases also manifest in the upper airways. PMID:24040372

    Introduction  Mechanical trauma to the nasal mucosa increases the risk of synechia formation, especially after chronic rhinosinusitis and nasal surgeries. Objective  This study was carried to assess the effect of propolis administration in healing injured nasal mucosa in rats. Methods  We randomly divided eighteen rats into three equal experimental groups: (1) non-treated group; (2) gum tragacanth (suspending agent for propolis) treated group; and (3) propolis treated group. The non-treated group received no treatment for 15 days. The second group received gum tragacanth administration (5 ml/kg, orally) once daily for 15 days. The third group received propolis suspension orally at a dose of 100 mg/kg once daily for 15 days. At the beginning of this study, we induced unilateral mechanical nasal trauma on the right nasal mucosa of all rats in the three groups using a brushing technique. A pathologist stained tissue samples using hematoxylin and examined eosin by using a light microscope. Results  The severity of inflammation was milder with the absence of ulcerations in the propolis treated group compared with the non-treated and gum tragacanth groups. Goblet cell and ciliated cell loss was substantially lower in patients treated with propolis compared with groups without treatment and those treated with gum tragacanth. Conclusion  Propolis decreased inflammation and enhanced healing of wounds of the nasal mucosa in rats. PMID:27413403

    Three hundred and thirty-four measurements of bilateral and unilateral nasal resistance (at delta P 1.0 cm H2O and by time averaging) in 233 adults were carried out by posterior rhinomanometry with a head-out body plethysmograph. Total nasal resistances, calculated by the equation of Ohm's Law for parallel resistors from measured unilateral resistances, were compared with measured total nasal resistances. The time averaged total nasal resistances calculated by use of Ohm's Law for parallel resistors were closer to direct measurements than resistances at delta P 1.0 cm H2O calculated from the same equation. We attempted to fit calculated total nasal resistance with direct measurements by modification of the equation of Ohm's Law for parallel resistors to T = 0.96[R x L/(R + L)]0.92 in the time averaged nasal resistance and T = 1.07[R x L/(R + L)]0.77 in resistance at delta P 1.0 cm H2O (T: total nasal resistance, R: nasal resistance on the right side, L: nasal resistance on the left side). Calculated total nasal resistances from the above equations agreed closely with direct measurements.

    Nasal drug delivery has now been recognized as a promising route for drug delivery due to its capability of transporting a drug to systemic circulation and central nervous system. Though nasal mucosa offers improved bioavailability and quick onset of action of the drug, main disadvantage associated with nasal drug delivery is mucocilliary clearance due to which drug particles get cleared from the nose before complete absorption through nasal mucosa. Therefore, mucoadhesive polymeric approach can be successfully used to enhance the retention of the drug on nasal mucosal surface. Here, some of the aspects of the stimuli responsive polymers have been discussed which possess liquid state at the room temperature and in response to nasal temperature, pH and ions present in mucous, can undergo in situ gelation in nasal cavity. In this review, several temperature responsive, pH responsive and ion responsive polymers used in nasal delivery, their gelling mechanisms have been discussed. Smart polymers not only able to enhance the retention of the drug in nasal cavity but also provide controlled release, ease of administration, enhanced permeation of the drug and protection of the drug from mucosal enzymes. Thus smart polymeric approach can be effectively used for nasal delivery of peptide drugs, central nervous system dugs and hormones. PMID:26664051

    A high rate of ENT doctors were murdered by nasal disordered patients in China recently. It is obviously important and urgent to find out whether there is any potential relationship between nasal diseases (ND) and psychological distress that might contribute to violent behavior. For this purpose, we carried out this literature review. There is a complex relationship between ND and psychiatric distress, which is mainly considered as a bidirectional causal relationship with other controversy opinions. However, most of the previous studies were found to be focused on allergic rhinitis and chronic rhinosinusitis, while reports about other ND were rare. Further study is still needed to uncover the secret aspects in this field, and more attentions need to be paid to other ND. PMID:26095351

    The authors present their experience with the correction of deformities of the nasal saddleback using rib cartilage grafts. They present a review of international literature on this topic, analyzing 33 patients selected from 452 cases of rhinoplasties performed between January 1990 and December 2004 at the Department of Plastic and Reconstructive Surgery of the University of Rome "Tor Vergata." Nasal saddleback is one of the most complicated defects to correct surgically. It can be a consequence of nasoethmoid-orbital fractures and is in this case associated with other evident signs like telecanthus, teleorbitism, or orbital dystopia. It can be also a consequence of surgical procedures in the nasal area where a loss of bone or septal cartilaginous support has occurred. They compare the techniques employed in the reconstruction and describe the advantage of the use of cartilage from the 11th rib and evaluate the results of an engineering analysis of tension forces on the rib cartilage. Of the total number of patients treated, good cosmetic results were obtained in 84% of the cases and excellent functional results in almost all of the cases (94%). PMID:16508354

    Juvenile angiofibroma, nasopharyngeal carcinoma (NPC) and lymphoepithelial carcinoma of the nasal cavity (LEC NC) all could be found as a hyper-vascular mass in the nasopharynx area. Performing biopsy for histopathologic confirmation is necessary in the case of NPC or LEC NC but could be fatal in the case of angiofibroma. In our case, a 21-year-old male who was suffering from unilateral nasal stuffiness and frequent epistaxis had a mass with an easily bleeding tendency in his right nasal cavity. Juvenile angiofibroma was suspected by clinical and radiologic examinations. We performed preoperative angiography and the feeding vessel from the right internal maxillary artery was obliterated with polyvinyl alcohol nanoparticle. The mass was completely removed endoscopically, and there was profound hemorrhage in spite of the preoperative embolization. The mass turned out to be LEC NC by postoperative histopathologic examination. To avoid this misdiagnosis, the authors suggest that we should perform biopsy under rigid endoscopy 24h after angiographic embolization. If the result of frozen biopsy is juvenile angiofibroma, we could perform surgery another 24h later. If the result is nasopharyngeal carcinoma or LEC NC, we could avoid unnecessary surgical removal and perform radiotherapy. In terms of treatment strategies, we suggest endoscopic removal of gross tumor and postoperative combination of chemoradiotherapy as the more curative regimen with less complications related with radiotherapy.

    The nasal cycle, through variation in nasal airflow partitioning, allows the upper airway to accommodate the contrasting demands of air conditioning and removal of entrapped air contaminants. The purpose of this study was to investigate the influence of nasal continuous positive airway pressure (nCPAP) breathing has on both nasal airflow partitioning and nasal geometry. Using a custom-made nasal mask, twenty healthy participants had the airflow in each naris measured during normal nasal breathing followed by nCPAP breathing. Eight participants also underwent magnetic resonance imaging (MRI) of the nasal region during spontaneous nasal breathing, and then nCPAP breathing over a range of air pressures. During nCPAP breathing, a simultaneous reduction in airflow through the patent airway together with a corresponding increase in airway flow within the congested nasal airway were observed in sixteen of the twenty participants. Nasal airflow resistance is inversely proportional to airway cross-sectional area. MRI data analysis during nCPAP breathing confirmed airway cross-sectional area reduced along the patent airway while the congested airway experienced an increase in this parameter. During awake breathing, nCPAP disturbs the normal inter-nasal airflow partitioning. This could partially explain the adverse nasal drying symptoms frequently reported by many users of this therapy.

    Endoscopic surgery is performed on patients with chronic inflammatory disease of the paranasal sinuses to improve sinus ventilation. Little is known about how sinus surgery affects sinonasal airflow. In this study nasal passage geometry was reconstructed from computed tomographic imaging from healthy normal, pre-operative, and post-operative subjects. Transient air flow through the nasal passage during calm breathing was simulated. Subject-specific differences in ventilation of the nasal passage were observed. Velocity magnitude at ostium was different between left and right airway. In FESS, airflow in post-surgical subjects, airflow at the maxillary sinus ostium was upto ten times higher during inspiration. In a Lothrop procedure, airflow at the frontal sinus ostium can be upto four times higher during inspiration. In both post-operative subjects, airflow at ostium was not quasi-steady. The subject-specific effect (of surgery) on sinonasal interaction evaluated through airflow simulations may have important consequences for pre- and post-surgical assessment and surgical planning, and design for improvement of the delivery efficiency of nasal therapeutics.

    From 1978 to 1992, 66 patients (32 women and 34 men) were treated for carcinoma of the nasal vestibule at Odense University Hospital. The treatment was radiotherapy (41 patients), surgery (13 patients) or a combination of the two modalities (12 patients). Twenty-one patients (32%) developed recurrence. Of these, 17 (81%) were diagnosed within the first two years of follow up. The recurrence rate was found to be correlated to the anatomic site of the tumour-origin; septal site of origin meant higher risk of recurrence. Five-year disease specific and crude survival of all patients were 87.0% and 58.5%, respectively. Several variables (sex, age, anatomic site of origin, Wang-classification, tumour volume and regional lymphnode metastases at time of diagnosis) were evaluated as possible prognostic indicators. In univariate analysis, regional lymph node metastases at the time of diagnosis and anatomic site of origin of the tumour showed a significant influence on survival. In multivariate analysis, septal origin of primary tumour was a significant, independent predictive factor of recurrence and the presence of lymph node metastases at the time of diagnosis showed to be a highly significant prognosticator of both disease specific and crude survival (p < 0.0001). We conclude that patients with primary lymph node metastases and septal location of primary tumour need intensive primary treatment and close follow up. PMID:10567990

    Unilateral obstruction of the nasal cavity in children is mainly caused by the introduction of foreign bodies further stated with rhinorrhea and fetid odor. Less commonly, it can be traumatic, neoplastic, due to congenital malformation or iatrogenic. Symptoms of congenital intranasal mass may present at birth, or go unnoticed and be a finding in a routine pediatric examination. Patient evaluation should include imaging studies to guide the diagnosis and rule out intracranial extension. A syndrome associated with congenital nasal tumor should be suspected when other abnormalities are present. Pai syndrome is a rare genetic disorder. Its manifestations are craniofacial being congenital nasal polyp his main marker. We present a patient with unilateral nasal respiratory failure secondary to congenital nasal lipoma, with craniofacial anomalies belonging to Pai syndrome. Nasal obstruction was successfully surgically resolved. PMID:22042063

    Vasomotor rhinitis is a condition of chronic nasal congestion which is noninfectious and nonallergic. Its cause is thought to be an imbalance of autonomic control to the nasal mucosa. This disorder is a diagnosis of exclusion, and other causes of chronic nasal obstruction must be considered first. Treatment measures include avoidance of nonspecific stimuli which exacerbate symptoms and, for symptomatic relief, use of oral sympathomimetics. Antihistamine-decongestant combinations may be effective in some patients. Topical vasoconstrictors should not be used.

    Background: Although combined oral and nasal steroid therapy is widely used in nasal polyposis, a subset of patients show an unfavorable therapeutic outcome. This study aimed to evaluate whether oral prednisolone produces any additive effects on subsequent nasal steroid therapy and to evaluate if any clinical variables can predict therapeutic outcome. Methods: Using a 3:2 randomization ratio, 67 patients with nasal polyposis received 50 mg of prednisolone and 47 patients received placebo daily for 2 weeks, followed by mometasone furoate nasal spray (MFNS) at 200 micrograms twice daily for 10 weeks. Clinical response was evaluated by nasal symptom score (NSS), peak expiratory flow index (PEFI), and total nasal polyps score (TNPS). Potential predictor variables were assessed by clinical history, nasal endoscopy, allergy skin test, and sinus radiography. Results: At the end of the 2-week oral steroid phase, the prednisolone group showed significantly greater improvements in all nasal symptoms, nasal airflow, and polyp size than the placebo group. In the nasal steroid phase, while the MFNS maintained the outcome improvements in the prednisolone group, all outcome variables in the placebo group showed continuing improvements. At the end of the nasal steroid phase, there were no significant differences of most outcome improvements between the two groups, except in hyposmia, PEFI, and TNPS (p = 0.049, p = 0.029, and p = 0.005, respectively). In the prednisolone group, patients with polyps grade 3 and endoscopic signs of meatal discharge showed significantly less improvement in total NSS, PEFI, and TNPS than patients with grade 1–2 size and negative metal discharge. Conclusion: In the 12-week treatment evaluation of nasal polyposis, pretreatment with oral steroids had no significant advantage for most nasal symptoms other than earlier relief; however, combined oral and nasal steroid therapy more effectively improved hyposmia, polyps size, and nasal airflow.

    Twenty-two patients with squamous carcinoma of the nasal vestibule were treated at the University of Florida Division of Radiation Therapy with curative intent. Fifteen lesions were de novo and seven recurrent after surgery. By AJCC classification, 7 lesions were Tx or T1, 2 were T2, 2 were T3, and 11 were T4. Management of the primary tumor and regional lymphatic drainage was highly individualized. Local control was achieved in 19 out of 22 lesions. The ultimate regional lymph node control rate was 22 out of 22, although two patients required radical neck dissection after development of lymph node disease in untreated regional lymphatics. Two patients have died of cancer and three of intercurrent disease. Cosmetic results are generally excellent but may be compromised by previous surgery in recurrent lesions or tumor destruction of normal tissues in advanced lesions. Complications of treatment are minimal.

For patients with realistic expectations, modern techniques of cosmetic facial surgery can enhance appearance and be of psychological benefit. Today most procedures can be done under local anesthesia on an out-patient basis. Facial contour defects can be improved by means of procedures such as rhinoplasty, mentoplasty, otoplasty and malarplasty. Facial rejuvenation surgery to decrease the signs of aging includes the forehead lift, eyebrow and eyelid lift, rhytidectomy, liposuction and chemical peeling. Newer controversial trends in cosmetic facial surgery include collagen implantation and fat transfer for contour defects, and eyelid tattooing.

    Objective: To determine the cumulative incidence of pregnancy rhinitis along with prevalence in different trimesters and to find out whether gestational age, BMI and parity have any effect on pregnancy related nasal congestion. Methods: In the prospective protocol at the obstetrics outpatient clinic, 167 pregnant women were enrolled consecutively. According to exclusion criteria, 67 of them were excluded. Visual-Analogue-Scale (VAS), Nasal-Obstructive-Symptom-Evaluation (NOSE) scale and Discharge-Inflammation-Polyps/Oedema (DIP) scoring were utilized for diagnosis of pregnancy rhinitis. Besides, weight, length, age, parity and week of pregnancy were recorded. Results: Total prevalence of pregnancy rhinitis was 17.17% and cumulative incidence was 38.89%. Our study revealed significant relation of NOSE score with both gestational week (r=0.474, p=0.001) and BMI (r=0.301, p=0.003). VAS score was significantly related with gestational week (r=0.409, p=0.001) and BMI (r=0.270, p=0.007). DIP score was found to be correlated only with gestational week (r=0.375, p=0.001). Conclusion: Cumulative incidence of pregnancy rhinitis was 38.89%. Nasal congestion was significantly associated with BMI and gestational week. Patients should be informed about unfavorable fetal and maternal outcomes of pregnancy related nasal congestion which is triggered by obesity and excessive weight gain in pregnancy. PMID:27648046

    Benzalkonium chloride is a preservative commonly used in nasal decongestant sprays. It has been suggested that benzalkonium chloride may be harmful to the nasal mucosa. Decongestion with the vasoconstrictor xylometazoline containing benzalkonium chloride has been shown to cause a significant reduction of the nasal mucosal temperature. The purpose of the present study was to determine the short-term influence of xylometazoline nasal spray with and without benzalkonium chloride on the nasal mucosal temperature. Healthy volunteers (30) were included in the study. Fifteen volunteers received xylometazoline nasal spray (1.0 mg/mL) containing benzalkonium chloride (0.1 mg/mL) and 15 age-matched subjects, received xylometazoline nasal spray without benzalkonium chloride. Using a miniaturized thermocouple the septal mucosal temperature was continuously measured at defined intranasal detection sites before and after application of the nasal spray. The mucosal temperature values did not significantly differ between the group receiving xylometazoline containing benzalkonium chloride and the group receiving xylometazoline spray without benzalkonium chloride before and after decongestion (P > 0.05). In both study groups septal mucosal temperatures significantly decreased after decongestion (P < 0.05) because of a reduction of the nasal mucosal blood flow following vasoconstriction. This study indicates that benzalkonium chloride itself does not seem to influence nasal blood flow and nasal mucosal temperature in topical nasal decongestants. PMID:15270822

    OBJECTIVE To compare patients' and physicians' visit-specific satisfaction in an internal medicine outpatient setting, and to explain their respective views. DESIGN patients' and physicians' background characteristics were assessed prior to outpatient encounters. Immediately after the encounter, both patients and physicians completed a questionnaire assessing satisfaction with the visit. SETTING The outpatient division of an academic teaching hospital. PARTICIPANTS Thirty residents and specialists in general internal medicine, rheumatology, and gastroenterology, and 330 patients having a follow-up appointment with one of these physicians. MEASUREMENTS AND MAIN RESULTS patients' and physicians' visit-specific satisfaction was assessed using 5 Visual Analogue Scales (0 to 100). patients' overall satisfaction was higher than physicians' satisfaction (mean 81 vs. 66), and correlation of patients' and physicians' overall satisfaction with the specific visit was medium sized (r= .28, P < .001). patients' satisfaction ratings were associated with their previsit self-efficacy in communicating with their physician (P < .001) and with visiting a female physician (P < .01). Physicians' satisfaction was associated with patients' higher educational level (P < .05), primary language being Dutch (P < .001), better mental health (P < .05), and preference for receiving less than full information (P < .05). CONCLUSIONS In an outpatient setting, patients' visit-specific satisfaction ratings were substantially higher than, and only moderately associated with, physicians' ratings of the same visit. The dissimilar predictors explaining patients' and physicians' satisfaction suggest that patients and physicians form their opinion about a consultation in different ways.

    Objective. We report a case of poor healing after endonasal surgery for nasal septal perforation ten years after cocaine abuse was ended. Method. The clinical findings are presented. Results. A 35-year-old man presented with a small nasal septal perforation caused by cocaine abuse. He had stopped using it ten years previously so surgery was considered safe. The perforation was surgically closed using an endonasal approach. The perforation, however, recurred, the incision healing delayed, and a saddle deformity developed. Conclusion. The effects of cocaine abuse seem to persist causing poor healing after nasal surgery. Prosthetic treatment should be the primary choice. Caution should be employed when considering surgery even in small perforations due to cocaine abuse even many years after the abuse was terminated. PMID:22953124

  9. Nasal obstruction in neonates and infants.

    PubMed

    Chirico, G; Beccagutti, F

    The main functions of the nasal airway are respiration and olfaction. The nose and sinuses condition air before reaching the lower respiratory tract by providing almost 100% humidification, warming, filtering and trapping of foreign particles. The airway epithelium contributes to the host defense system. Any alteration of this clearance system may produce significant problems, particularly in neonates, who are obligate nasal breathers until they are at least two months old. Nasal obstruction, and the inability to remove nasal secretion by nose blowing, may have serious consequences, such as respiratory distress or discomfort, altered sleep cycle, increased risk of obstructive apnoea and feeding difficulties. Most cases of nasal obstruction in neonates and infants are due to generalized nasal airway obstruction associated with neonatal rhinitis, viral upper respiratory tract infections, and possibly milk/soy allergies. Saline nasal lavage is recommended as an adjunct therapy for rhinosinusitis and allergic rhinitis, and in most cases of nasal congestion or obstruction in newborns, infants and children. In two recent experiences, was deemed to be the Narhinel method safe and effective for treatment of nasal congestion in babies with viral infections of the upper respiratory tract, or for the prevention of acute otitis media (AOM) and acute rhinosinusitis (AR) in children. Due to the efficacy, ease of use, tolerability and the lack of alternative medications in children younger than 12 years of age, nasal irrigation with physiological saline solution, followed by gentle aspiration, represent an effective method for the prevention and control of nasal congestion or obstruction in term or preterm neonates, infants and children.

    Numbered nasal discs were successfully used in studies requiring large numbers of individually marked waterfowl. The procedure for constructing these discs is outlined. Blue-winged teal (Anas discors) with 5/8-inch discs, and canvasback (Aythya valisineria) and redhead (A. americana) with 3/4-inch discs can be individually identified up to 50 and 80 yards, respectively, with a gunstock-mounted, 20-power spotting scope. The particular value of these markers is their durability, the number of combinations possible, and the apparent absence of behavioral or mortality influence among such species as the blue-winged teal.

    A 6-yr-old male Vancouver Island marmot (Marmota vancouverensis) presented for poor hibernation, weight loss, and symmetric trunk alopecia. An abdominal interstitial cell tumor was identified and surgically removed. Serum levels of estrogen were markedly elevated before surgery and decreased after tumor removal, indicating that the tumor had been functionally secretory. Nine months later, the marmot presented with respiratory stridor. A large boney nasal mass was identified radiographically and evaluated by computed tomography (CT) prior to surgical debulking. The marmot did not recover from anesthesia. Pathologic findings included a nasal osteosarcoma with lysis of the cribriform plate, and endocardial fibrosis with degenerative changes within the adjoining myocardium. This is the first known report of nasal osteosarcoma and interstitial tumor in a Vancouver Island marmot.

    A cross-sectional study was performed in children 5 through 10 years of age presenting to outpatient clinics in Nyanza Province, Kenya, in which nasal swab and blood specimens were collected during the high malaria transmission season. Patients presenting with malaria-like symptoms within 4 days of fever onset were enrolled in the study. Plasmodium parasitemia was determined by blood smear microscopy. Nasal swabs were screened for a panel of respiratory viruses by polymerase chain reaction. Influenza A, rhinoviruses, and other respiratory viruses were detected in 18%, 26%, and 12% of 197 specimens, respectively. Four of 36 patients with influenza A had a positive malaria blood slide, compared with 20 of 52 patients with rhinovirus. A significant burden of disease caused by influenza A in febrile children during the study period was observed, highlighting the need for further research into the burden of influenza disease in regions where malaria is holoendemic.

    The use of local anesthesia and intravenous sedation has made same-day outpatient surgery a viable option for many aesthetic and reconstructive procedures. These procedures often include the use of supplemental oxygen. Oxygen-enriched environments increase the combustibility of most materials, and "oxygen pooling" has been suspected to play an integral role in intraoperative fires. A personal experience with an intraoperative explosion and fire during a cosmetic blepharoplasty compelled us to explore the potential danger inherent in the use of supplemental oxygen as well as potential strategies to minimize that danger. This study systematically examines the microenvironment created by the use of oxygen both in the operative field and beneath the surgical drapes under conditions simulating routine facial surgery and various recommended modifications of its delivery. With the use of oxygen supplementation, oxygen concentration beneath the drapes was found to be consistently elevated when compared with ambient air (20.9 percent) and reached levels as high as 53.5 percent. Oxygen concentration in the operative environment was mildly but not significantly elevated. Although criteria for the use of oxygen supplementation are not clear, when administration is deemed necessary, the use of a posterior pharyngeal catheter for its delivery had no advantage over nasal prongs. However, appropriate alternatives include the use of "open face" draping techniques, the use of compressed air beneath the drapes as a substitute for oxygen supplementation in unsedated patients, and cessation of oxygen supplementation for 60 seconds prior to the use of a possible ignition source with oxygen flow rates of less than 3 liters per minute.

    The mini C-arm image intensifier (mini C-arm) has now become an established diagnostic tool in the hand surgery outpatient department. This study reviews the use of the mini C-arm and formal radiographs (X-rays) in the outpatient hand surgery setting. X-rays provide a standard image whereas the mini C-arm can obtain non-standard images to aid diagnosis and treatment. The mini C-arm enables the clinician to obtain dynamic images and perform interventions such as manipulations or injections. The mini C-arm results in a significantly lower radiation exposure for the patients than a formal X-ray. Use of the mini C-arm may be cheaper, and can lead to a shorter outpatient visit with less travel between hospital departments.

    Two cases of nasal pythiosis are reported in horses from the semi-arid region of northeastern Brazil. From January 1986 to December 2015, the Laboratory of Animal Pathology, Federal University of Campina Grande received 830 equine samples, 156 (18.79%) of which were diagnosed with pythiosis. Of these, two horses (1.28%), a male and a female adult cross-breed, had lesions in the nasal cavity. Both horses had access to water reservoirs. Clinically, they had swelling in the rhinofacial region and a serosanguineous nasal discharge. Macroscopically, in case 1, the lesion affected the nasal vestibule, extending to the alar cartilage and nasal septum. In case 2, the lesion extended through the turbinates and the meatuses of the nasal cavity, as well as the ethmoid region. In both cases, the lesions were characterized by having a yellow-grey granular surface with cavitations of different sizes containing coral-like masses of necrotic tissue (kunkers). Histologically, multifocal necrotizing eosinophilic rhinitis associated with hyphae (2-8 μm) similar to Pythium insidiosum were observed. In case 2, the lesions extended to the muscle, cartilage and bone adjacent to the nasal cavity and lungs. The diagnosis was confirmed by immunohistochemistry. It is concluded that nasal pythiosis occurs sporadically in horses in the semi-arid region of northeastern Brazil where cutaneous pythiosis is prevalent. PMID:27406311

    2014-01-01

    Background The microbiota of the nares has been widely studied. However, relatively few studies have investigated the microbiota of the nasal cavity posterior to the nares. This distinct environment has the potential to contain a distinct microbiota and play an important role in health. Results We obtained 35,142 high-quality bacterial 16S rRNA-encoding gene sequence reads from the nasal cavity and oral cavity (the dorsum of the tongue and the buccal mucosa) of 12 healthy adult humans and deposited these data in the Sequence Read Archive (SRA) of the National Center for Biotechnology Information (NCBI) (Bioproject: PRJNA248297). In our initial analysis, we compared the bacterial communities of the nasal cavity and the oral cavity from ten of these subjects. The nasal cavity bacterial communities were dominated by Actinobacteria, Firmicutes, and Proteobacteria and were statistically distinct from those on the tongue and buccal mucosa. For example, the same Staphylococcaceae operational taxonomic unit (OTU) was present in all of the nasal cavity samples, comprising up to 55% of the community, but Staphylococcaceae was comparatively uncommon in the oral cavity. Conclusions There are clear differences between nasal cavity microbiota and oral cavity microbiota in healthy adults. This study expands our knowledge of the nasal cavity microbiota and the relationship between the microbiota of the nasal and oral cavities. PMID:25143824

    Study Design Retrospective population-based observational study. Objective To assess the growth of cervical spine surgery performed in an outpatient setting. Methods A retrospective study was conducted using the United States Healthcare Cost and Utilization Project's State Inpatient and Ambulatory Surgery Databases for California, New York, Florida, and Maryland from 2005 to 2009. Current Procedural Terminology, fourth revision (CPT-4) and International Classification of Diseases, ninth revision Clinical Modification (ICD-9-CM) codes were used to identify operations for degenerative cervical spine diseases in adults (age > 20 years). Disposition and complication rates were examined. Results There was an increase in cervical spine surgeries performed in an ambulatory setting during the study period. Anterior cervical diskectomy and fusion accounted for 68% of outpatient procedures; posterior decompression made up 21%. Younger patients predominantly underwent anterior fusion procedures, and patients in the eighth and ninth decades of life had more posterior decompressions. Charlson comorbidity index and complication rates were substantially lower for ambulatory cases when compared with inpatients. The majority (>99%) of patients were discharged home following ambulatory surgery. Conclusions Recently, the number of cervical spine surgeries has increased in general, and more of these procedures are being performed in an ambulatory setting. The majority (>99%) of patients are discharged home but the nature of analyzing administrative data limits accurate assessment of postoperative complications and thus patient safety. This increase in outpatient cervical spine surgery necessitates further discussion of its safety.

    Chronic rhinosinusitis without nasal polyps (CRSsNP) is more prevalent than chronic rhinosinusitis with nasal polyps (CRSwNP). Certain diseases predispose to whereas others are associated with CRSsNP. Predisposing diseases include allergic and nonallergic upper and lower airway diseases, epithelial cell disorders, immunodeficiencies, autoimmune diseases, and some infectious diseases. In addition, environmental and host factors, examples of which include smoking, a higher incidence of abnormal biofilms, and innate immune defects, play a role in the pathogenesis of this disease. CRSsNP is characterized by histologic abnormalities, including basement membrane thickening (fibrosis) and goblet cell hyperplasia. Neutrophils and several chemokines, TGF-β and C-X-C motif chemokine ligand (CXCL)-8, play a role in CRSsNP remodeling. However, there are conflicting data about CRSsNP endotypes, for example, whether it is characterized by neutrophilia or eosinophilia or both. In spite of advancements and the understanding of the pathogenesis of this disease, additional study is necessary to better comprehend its underlying mechanisms, endotypes, and evidence-based treatment strategies.

    This paper describes numerical simulation of airflow in a nose with a nasal septal perforation. Diseased airflow is compared to airflow in a healthy nasal model. The healthy model has been generated from CT scans from the Antrim Area Hospital ENT clinic and is close to being anatomically accurate. The nasal septal perforation has been superimposed on the healthy geometry using image manipulation software. The flow is modeled as laminar, steady state, with the flow rates corresponding to quiet breathing at rest approximately 165 ml/sec. Healthy flow patterns show that the majority of the flow travels close to nasal septum, in the region close to the middle turbinate. In the diseased case, high shear stresses concentrated at the posterior region of the perforation explain bleeding associated with nasal perforations.

  5. Restorative procedures in disturbed function of the upper airways - nasal breathing

    PubMed Central

    Mlynski, Gunter

    2005-01-01

    These days, functional rhinosurgery is almost always taken to mean the improvement of nasal airflow. However, air should not only pass through the nose without obstruction. It needs to be warmed, moistened and filtered. This requires sufficient air/mucous membrane contact by spreading airflow over the entire turbinate region, as well as regulation of nasal airway resistance and the degree of turbulence within the nasal cycle. These factors are not considered enough in the concept of functional rhinosurgery. There cannot be a rigid concept for functional/aesthetic rhinosurgery, the surgical procedure must be adapted to the individual anatomy and pathology. In spite of this, it must be clear (based on evidence) which surgical steps can solve a functional problem of the nose in the long term. This paper cannot explain evidence-based treatment strategies to restore nasal respiratory function because in all branches of rhinosurgery, there are no prospective studies available with a sufficiently high sample size and long-term results objectivized by functional diagnosis. Studies available on septal surgery show better results for SP after Cottle than for SMR after Killian. However, the success rate of a 70 to 80% improvement in nasal breathing is not satisfactory. The incidence of postoperative, dry nasal mucosa is also too high. The task of rhinology is to stress the functional side of rhinosurgery more. This includes preoperative analysis of the causes of disturbed respiratory function using the functional diagnosis methods available, the use of evidence-based surgical techniques and postoperative, objectivized quality control. More research needs to be done on the physiology and pathophysiology of nasal airflow as well as on the effect of rhinosurgery on airflow. Numerical flow simulation can contribute greatly to this because the effects of shape changes on the flow can be visualized. Methods need to be developed which can be used for routine, diagnostic recording of

    Background Cephalometric analysis is essential for planning treatment in maxillofacial and aesthetic facial surgery. Although photometric analysis of the Korean nose has been attempted in the past, anthropometry of the deeper nasal structures in the same population based on computerized tomography (CT) has not been published. We therefore measured three anthropometric parameters of the nose on CT scans in our clinical series of patients. Methods We conducted the current retrospective study of a total of 100 patients (n=100) who underwent a CT-guided radiological measurement at our institution during a period ranging from January of 2008 to August of 2010. In these patients, we took three anthropometric measurements: the nasofrontal angle, the pyramidal angle, and the linear distance between the nasion and the tip of the nasal bone. Results The mean nasofrontal angle was 131.14° in the male patients and 140.70° in the female patients. The mean linear distance between the nasion and the tip of the nasal bone was 21.28 mm and 18.02 mm, respectively. The mean nasal pyramidal angle was 112.89° and 103.25° at the level of the nasal root, 117.49° and 115.60° at the middle level of the nasal bone, and 127.99° and 125.04° at the level of the tip of the nasal bone, respectively. Conclusions In conclusion, our data will be helpful in the preparation of silicone implants for augmentation and/or corrective rhinoplasty in ethnic Korean people. PMID:24086818

  8. Subjective Nasal Fullness and Objective Congestion

    PubMed Central

    Baraniuk, James N.

    2011-01-01

    How well do subjective descriptions of the sensation of nasal closure or absence of nasal patency agree with objective measures of nasal geometry and airflow? Problems with this concept begin with terminology. “Congestion” has been applied to both the subjective and objective measures. Therefore, the term “fullness” will be used to describe perceptions of nasal mucosal heaviness or blockage that subjects with allergic rhinitis articulate. “Congestion” will refer to the objective measures used to assess patency. Sensations attributed to the nasal mucosa are highly integrated interpretations summed from multiple subsets of nociceptive and other neurons. Activation of sensor systems is required to depolarize afferent neurons. These sensors and other receptor proteins can be modulated by inflammation as part of the neural plasticity that leads to increased sensitivity to nasal stimuli. This plasticity and hyperalgesia may extend from the afferent neuron to spinal cord dorsal horn synapses, and regulatory and analytical regions of the brainstem and cerebrum. Although glandular hypersecretion can deliver obstructing material into the nasal cavities, the dilation of deep venous sinusoids is the strongest factor regulating nasal airspace volumes. There is a long history of attempts to correlate subjective sensations to objective measurements such as airflow resistance (rhinomanometry), nasal wall geometry (acoustic rhinometry), and peak nasal inspiratory flow. The medical evidence supporting each method has been analyzed on the basis of the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) system. These results provide a starting point for linking the outcomes of pathophysiological processes with a patient's psychometrically calibrated sensation of airflow. PMID:21364223

    Background Over one hundred different pharmaceutical dosage forms have been recorded in literatures of Traditional Persian Medicine among which nasal forms are considerable. Objectives This study designed to derive the most often applied nasal dosage forms together with those brief clinical administrations. Materials and Methods In the current study remaining pharmaceutical manuscripts of Persia during 9th to 18th century AD have been studied and different dosage forms related to nasal application of herbal medicines and their therapeutic effects were derived. Results By searching through pharmaceutical manuscripts of medieval Persia, different nasal dosage forms involving eleven types related to three main groups are found. These types could be derived from powder, solution or liquid and gaseous forms. Gaseous form were classified into fumigation (Bakhoor), vapor bath (Enkebab), inhalation (Lakhlakheh), aroma agents (Ghalieh) and olfaction or smell (Shomoom). Nasal solutions were as drops (Ghatoor), nasal snuffing drops (Saoot) and liquid snuff formulations (Noshoogh). Powders were as nasal insufflation or snorting agents (Nofookh) and errhine or sternutator medicine (Otoos). Nasal forms were not applied only for local purposes. Rather systemic disorders and specially CNS complications were said to be a target for these dosage forms. Discussion While this novel type of drug delivery is known as a suitable substitute for oral and parenteral administration, it was well accepted and extensively mentioned in Persian medical and pharmaceutical manuscripts and other traditional systems of medicine as well. Accordingly, medieval pharmaceutical standpoints on nasal dosage forms could still be an interesting subject of study. Therefore, the current work can briefly show the pharmaceutical knowledge on nasal formulations in medieval Persia and clarify a part of history of traditional Persian pharmacy. PMID:24624204

    The incidence of infectious endocarditis is fairly stable over the past decades. It is estimated at roughly 3-4 case per patient-year. However, as a consequence of medical progress, Staphylococcus aureus endocarditis has become more prevalent. This is particularly true for health-care associated endocarditis, especially in iv-drug abusers or hemodialysis patients. Mortality (15-20% of patients in the last series) remains high. About 50% of patients undergo surgical treatment, whereas outpatient therapy is more and more frequent for highly selected subgroups of patients without complications and infected with low-risk organims. The present paper reviews in detail the epidemiology of infective endocarditis and discuss in detail the different out-patients therapies.

    Objective: A variety of nasal skin reconstruction methods are available to meet the esthetic patient's needs. In this article, we review some of modifications of these procedures and share our experience in reconstruction of different parts of the nasal skin following skin tumor ablation. Patients and Methods: From January 2010 to January 2014, 171 patients underwent nasal skin reconstruction after excising cancerous lesions of the involved nasal skin. The patient's history, pre- and post-operation photographs, and the surgery data were collected and assessed. Demographic data related to the type of cancer, defect size and location, type of reconstruction were collected. Results: A variety of local flaps were used based on location and defect features. Nearly all flaps healed primarily without postsurgical significant complications. Conclusion: According to the results and the outcomes of the operations, we concluded that a certain flaps are more effective than others in nasal skin reconstruction. Local flap reconstruction of the nose has good esthetic result with low complication rate. PMID:27761088

    The relationship between nasalance scores and perceptual judgments of hypernasality and hyponasality was examined for 74 subjects (51 with cleft palate and 23 noncleft controls). Twenty-nine of the 51 subjects with cleft palate had received pharyngeal flap surgery. Predictive analyses were performed to assess the sensitivity, specificity, and efficiency of the Nasometer as a screening instrument. The overall relationship between perceptual judgments of hypernasality and nasalance scores was good for the nonflap subjects when a nasalance cutoff score of 26 was used. A sensitivity coefficient of 0.87 and a specificity coefficient of 0.93 were obtained. Ninety-one percent of the nasometry-based classifications accurately reflected listener judgments of hypernasality. The correspondence between nasalance scores and clinical judgments of hyponasality was also good for the nonflap subjects when a nasalance cutoff score of 50 was used. Ninety-one percent of these classifications were consistent with the listener judgments. Efficiency of nasometry was poorer for the flap subjects.

    Introduction: Dorsal nasal irregularity is a complication of rhinoplasty surgery, mostly seen in patients with thin skin. Acellular dermis (CenoDerm) and homologous fascia lata covering the nasal bone cartilage structure have been used to achieve a smooth surface. In this study, we aimed to investigate clinical outcomes using these two materials. Materials and Methods: After a standard rhinoplasty procedure, a layer of the acellular dermis or homologous fascia lata was placed in the pocket of the dorsum. Patients were evaluated for clinical outcomes at 3, 6, and 12 months after the procedure. Results: Forty-two of 68 patients completed the follow-up period. Patient satisfaction was higher in the homologous fascia lata group. Similarly, nasal dorsum inspection and palpation results were better in the homologous fascia lata group compared with the CenoDerm group but was significant in palpation (P=0.00). There was no complete absorption in the homologous fascia lata group 6 months after surgery (P= 0.04 vs. CenoDerm) but no significant difference was observed at 12 months. Conclusion: Homologous fascia lata is better than acellular dermis in preventing dorsal nasal irregularity after rhinoplasty in thin-skinned patients. PMID:27602334

  15. Solo hand surgery.

    Unassisted hand surgery is being undertaken by necessity for both elective and emergency cases, due to hospital resource restrictions. The authors outline the principles of local anesthesia, surgeon-controlled tourniquet techniques, and a number of new instruments which allow a surgeon to work in comfort and safety, unassisted. The traditional surgical instruments designed for the days when trained surgical assistants were available to hold them are no longer suitable. We are entering a new era of surgical design with safer instruments that can complement our skills rather than challenge them. There are significant cost savings and efficiency when hand procedures are undertaken in the emergency and outpatient clinic settings.

    From January 2010 to December 2012, 296 skin biopsies were performed in pediatric patients using only local anesthesia (cream and infiltration). The biopsies were divided into three groups: biopsies of skin neoplasms, biopsies of skin rashes and biopsies of follicular-centered lesions. Our data demonstrate the possibility of using this procedure, with the dual advantage of eliminating hospitalization and cost savings. PMID:25490940

    Objectif : Estimer la réaction des patients à un traitement de physiothérapie en groupe de courte durée (de 4 à 6 semaines) à la suite d'une arthroplastie du genou en ce qui concerne la douleur, la fonction et la satisfaction. Méthode : L'étude a utilisé un concept prospectif d'observation. Au total, 169 patients (111 femmes) ayant subi une arthroplastie du genou ont été recrutés de façon consécutive pour assister deux fois par semaine à un cours axé sur la mobilité, la force, l'équilibre et le recyclage fonctionnel. Les changements relatifs à la douleur, à la fonction et à la satisfaction ont été mesurés à l'aide du questionnaire sur l'intensité de la douleur (P4), de l'échelle fonctionnelle des membres inférieurs (EFMI), d'un test de l'escalier chronométré (TEC), d'une mesure de l'amplitude des mouvements (ADM) du genou, de l'échelle fonctionnelle spécifique au client (EFSC) et du questionnaire de satisfaction de la clientèle (CSQ-8). À l'aide de STATA 12.1, les données ont été résumées de façon descriptive et les valeurs numériques des changements ont été calculées avec des intervalles de confiance de 95%. Résultats : En moyenne, les patients ont obtenu leur congé en 11 séances ou moins, leurs objectifs de traitement ayant été atteints. Plus de 77% des participants ont dépassé le seuil de changement détectable à un niveau de confiance de 90% (CDM90) pour les évaluations de l'EFMI, du TEC, de l'EFSC et de l'ADM. La note moyenne au CSQ-8 à l'obtention du congé était de 31,8 (ET 1,46); une note parfaite de 32 a été obtenue dans 66,7% des cas. Conclusions : Les patients ayant participé à un cours de courte durée en service externe après une arthroplastie du genou ont affiché une nette amélioration en ce qui concerne la douleur et la fonction des extrémités inférieures et se sont montrés très satisfaits de leur traitement de physiothérapie.

  19. Disorders of the nasal valve area

    PubMed Central

    Bloching, Marc Boris

    2008-01-01

    The nasal valve area is not a singular structure, but a complex three-dimensional construct consisting of several morphological structures. From the physiologic point of view, it is the place of maximum nasal flow resistance (“flow limiting segment”). Therefore, according to Poiseuille’s law, even minor constrictions of this area result in a clinically relevant impairment of nasal breathing for the patient. This narrow passage, also called “ostium internum nasi”, is formed by the mobile lateral nasal wall, the anterior septum with the swell body, the head of the inferior turbinate and the osseous piriform aperture. Within the framework of aetiology, static and dynamic disorders of the nasal valve area have to be distinguished since they result in different therapeutic measures. In the context of diagnosis, the exploration of the case history for assessing the patient’s extent of suffering and the clinical examination are very important. In addition to the presentation of the basics of disorders of the nasal valves, this paper focuses on the treatment of dynamic disorders that mainly constitute the more important therapeutic issue. In this context, we distinguish between stabilisation techniques through grafts or implants and stabilising suture techniques. Following a thorough analysis, the correction of static nasal valve disorders requires various plastic-reconstructive measures using transposition grafting and skin or composite grafts.

    Whether nasal congestion promotes obstructive sleep apnea is controversial. Therefore, we performed a randomized placebo-controlled cross-over trial on the effects of topical nasal decongestion in patients with obstructive sleep apnea syndrome (OSA) and nasal congestion. Twelve OSA patients with chronic nasal congestion (mean +/- SD age 49.1 +/- 11.1 years, apnea/hypopnea index 32.6 +/- 24.5/h) were treated with nasal xylometazoline or placebo for 1 week each. At the end of treatment periods, polysomnography including monitoring of nasal conductance by an unobtrusive technique, vigilance by the OSLER test, and symptom scores were assessed. Data from xylometazoline and placebo treatments were compared. Mean nocturnal nasal conductance on xylometazoline was significantly higher than on placebo (8.6 +/- 5.3 versus 6.3 +/- 5.8 mL s(-1)Pa(-1), P < 0.05) but the apnea/hypopnea index was similar (29.3 +/- 32.5/h versus 33.2 +/- 32.8/h, P = NS). However, 30-210 min after application of xylometazoline, at the time of the maximal pharmacologic effect, the apnea/hypopnea index was slightly reduced (27.3 +/- 30.5/h versus 33.2 +/- 33.9/h, P < 0.05). Xylometazoline did not alter sleep quality, sleep resistance time (33.6 +/- 8.8 versus 33.4 +/- 10.1 min, P = NS) and subjective sleepiness (Epworth score 10.5 +/- 3.8 versus 11.8 +/- 4.4, P = NS). The reduced apnea/hypopnea index during maximal nasal decongestion by xylometazoline suggests a pathophysiologic link but the efficacy of nasal decongestion was not sufficient to provide a clinically substantial improvement of OSA.

    1993-01-01

    Nine patients (8 men and 1 woman, ranging in age from 17 to 22 years) who sustained a Jones fracture were treated with percutaneous intramedullary screw fixation as outpatients. All of the patients were varsity athletes. Seven were Division I scholarship athletes. Beginning at 7 to 10 days after surgery, all patients were allowed weightbearing as tolerated with a CAM walker. Stationary bicycling, swimming, and Stairmaster were allowed at 2 to 3 weeks. The average return to running was 5.5 weeks (range, 3 to 10). The average return to full competition was 8.5 weeks (range, 7 to 12). No perioperative or postoperative complications occurred. Average followup was 2.5 years. All fractures attained clinical and radiographic union. We believe that outpatient percutaneous intramedullary screw fixation of the acute Jones fracture is a reasonable alternative for those active patients who would have difficulty with a non-weightbearing cast and crutches or who desire an expeditious return to activities. Time restraints are particularly critical for in-season or preseason athletes. With the outpatient screw fixation method, our patient population had predictable healing, and they returned to full sports participation within 12 weeks.

    2016-01-01

    Allergic rhinitis is a major chronic respiratory disease and an immunoneuronal disorder. We aimed at providing further knowledge on the function of the neural system in nasal allergic reaction. Here, a method to assess simultaneously the nasal airflow resistance and the underlying function of autonomic nervous system (ANS) is presented and used during the nasal provocation of allergic and nonallergic subjects. Continuous nasal airflow resistance and spectral heart rate variability parameters show in detail the timing and intensity differences in subjects' reactions. After the provocation, the nasal airflow resistance of allergic subjects showed a positive trend, whereas LF/HF (Low Frequency/High Frequency) ratio and LF power showed a negative trend. This could imply a gradual sympathetic withdrawal in allergic subjects after the allergen provocation. The groups differed significantly by these physiological descriptors. The proposed method opens entirely new opportunities to research accurately concomitant changes in nasal breathing function and ANS. PMID:27196870

    A prospective single blinded interventional study was held in Otorhinolaryngology Clinic, Universiti Kebangsaan Malaysia Medical Centre in August 2010 until November 2012 to evaluate the functional outcome of septorhinoplasty objectively and subjectively. Objective assessment was done using rhinomanometry and subjective assessment using Nasal Obstruction Symptoms Evaluation (NOSE) scale and Health-Related Quality of Life Questionnaires (HRQOL) in Rhino Surgery. All measurements were taken preoperatively and 3 months postoperatively. A total of 29 patients were enrolled and completed the study. Septorhinoplasty was commonly performed in Malays and Indians and rare amongst Chinese, with age ranged from 18 to 54 years. Majority had no history of trauma. Twisted nose was the most common external nose abnormality followed by crooked and saddle nose. All patients had internal valve insufficiency. There were significant improvement of the total and of all the parameters in the NOSE scale post septorhinoplasty (p < 0.05). Furthermore, there were significant improvement in total and in all parameters in HRQOL score post septorhinoplasty (p < 0.05). There were improvements in the rhinomanometry data bilaterally during inspiration and expiration, but were not statistically significant (p > 0.05). Significant correlations were noted in the improvement between the two subjective assessments (NOSE scale and HRQOL score). However, there was no significant correlation in the improvement between the subjective (NOSE scale and HRQOL score) with objective (rhinomanometry score) assessments. Septorhinoplasty improves the nasal airflow and quality of life of patients with nasal obstruction. PMID:27340641

    Nasal polyp causes difficulty in breathing due to blockage of nasal passage. The pathogenesis of nasal polyposis is not known. The primary medical therapy available for nasal polyposis is steroid administration. Antihistamines, decongestants and cromolyn sodium provide little benefit. With this background of nasal polyp pathophysiology and the existing management, a case of nasal polyp was treated with the cleansing process of yoga i.e. neti kriya and naturopathy with good result. This isolated case report warrants a need for controlled clinical trial of neti kriya to establish its role in the management of nasal polyposis.

    Olfactory mucus provides the perireceptor environment in which the initial steps of olfactory signal transduction occur [5]. Extrinsic autonomic and trigeminal innervation controls mucus secretion and may release neurotransmitters into nasal mucus [13]. We quantitated catecholamines in rat nasal mucus and found that catecholamine levels first increased and then declined with trigeminal stimulation. These data indicate that catecholamine levels are regulated in nasal mucus and could modulate the odor sensitivity of olfactory sensory neurons.

    Endonasal endoscopic sinus surgery is the standard procedure for surgery of most paranasal sinus diseases. Appropriate frame conditions provided, the respective procedures are safe and successful. These prerequisites encompass appropriate technical equipment, anatomical oriented surgical technique, proper patient selection, and individually adapted extent of surgery. The range of endonasal sinus operations has dramatically increased during the last 20 years and reaches from partial uncinectomy to pansinus surgery with extended surgery of the frontal (Draf type III), maxillary (grade 3–4, medial maxillectomy, prelacrimal approach) and sphenoid sinus. In addition there are operations outside and beyond the paranasal sinuses. The development of surgical technique is still constantly evolving. This article gives a comprehensive review on the most recent state of the art in endoscopic sinus surgery according to the literature with the following aspects: principles and fundamentals, surgical techniques, indications, outcome, postoperative care, nasal packing and stents, technical equipment.

    Medication errors may occur during parental administration of prescription and over-the-counter medications in the outpatient pediatric setting. Misinterpretation of medication labels and dosing errors are two types of errors in medication administration. Health literacy may play an important role in parents' ability to safely manage their child's medication regimen. There are several proposed strategies for decreasing these medication administration errors, including using standardized dosing instruments, using strictly metric units for medication dosing, and providing parents and caregivers with picture-based dosing instructions. Pediatric healthcare providers should be aware of these strategies and seek to implement many of them into their practices. PMID:27537086

    Surgery in outpatients and surgery under hospital conditions should provide the patient with the same high level of quality and the same low risk level. The one-person surgery practice is able to offer the patient a classic "one client-one customer" relation. Thus, the continuity of treatment is optimal. On the other hand, intervening systemic complications are more easily managed by the multidisciplinary staff of a hospital with its equipment. The weaknesses of both principles can be counteracted by employing special precautions in organization. The future of surgery is to be seen in combined forms, for example, in-sourcing of a surgeon from private practice into a hospital. PMID:14991173

    Nasal chondromesenchymal hamartoma (NCMH) is a benign tumor that was described in 1998. The occurrence of this lesion in the nasal cavity of infants and children is especially rare, with only 21 cases reported in the international literature. We report a 12-month-old boy with respiratory distress due to nasal obstruction. Computed tomographic scan and magnetic resonance imaging examination demonstrated a soft-tissue mass obstructing the left nasal cavity. Digital subtraction angiography and preoperative superselective embolization with microparticles were also performed. The tumor was completely resected surgically. Histopathology and immunohistochemical analyses of the tumor disclosed a NCMH. The imaging characteristics of the tumor are described and the radiology literature is reviewed.

    2000-01-01

    Nasal insufflation of cocaine injures the nasal mucosa and can perforate the septum. Cocaine-induced vasoconstriction resulting in ischemia is one of the methods that may be responsible for this damage. We are determining whether cocaine also produces a hypercoagulable state that may compound factors which have been previously established to cause damage to the nasal mucosa and septum. This study uses Modified Recalcification Time (MRT), a test developed in our laboratory that has the ability to measure the overall coagulation process. Our study revealed no connection between cocaine and enhanced platelet function or monocyte-released tissue factor. The coagulation process was unaffected by the addition of the drug, so we conclude that cocaine does not cause a hypercoagulable state and cannot assist in the explanation regarding the ischemic changes of the nasal septum.

    Abstract Nasal foreign bodies may result from the abundant availability of tiny objects in our society and a curious child exploring his or her nasal cavities. An inserted object that is not witnessed or retrieved can remain relatively asymptomatic or cause local tissue damage and potentially yield more serious consequences. An unusual case of a young child who presented for dental rehabilitation under general anesthesia is described. Immediately prior to the nasotracheal intubation, an unanticipated foreign body was detected and safely removed before any injury occurred. This case report discusses the presentation and pathophysiology of nasal foreign bodies. Moreover, applicable suggestions are provided to aid in the prevention and management of the unexpected discovery of a nasal foreign body after the induction of general anesthesia.

    PubMed

    Klima, M

    1999-01-01

    The adaptation of cetaceans to aquatic life habits is reflected, in their nasal region, in three marked changes from the original relations found in land mammals. These changes include (1) the loss of the sense of smell, (2) translocation of the nostrils from the tip of the rostrum to the vertex of the head, and (3) elongation of the anterior head to form a rostrum protruding far towards anterior. The morphogenetic processes taking place during embryogenesis of the nasal skull play a decisive part in the development of all these changes. The lateral parts of the embryonic nasal capsule, encompassing the nasal passages, change their position from horizontal to vertical. At the same time, the structures of the original nasal floor (the solum nasi) are shifted in front of the nasal passages towards the rostrum. The structures of the original nasal roof (the tectum nasi) and of the nasal side wall (the paries nasi) are translocated behind the nasal passages towards the neurocranium. The medial nasal septum (the septum nasi) mostly loses its connection to the nasal passages and is produced into a point protruding far towards anterior. The transformed embryonic nasal skull of the Cetacea can be divided into three sections: 1. The median structures. These include the cartilaginous structures, viz., the rostrum nasi, the septum interorbitale and the spina mesethmoidalis, which are accompanied by the dermal bones, the vomer and the praemaxillare. In adult cetaceans the rostrum nasi is mostly preserved as a robust cartilage of the skull, which may possibly serve as a sound transmitting structure of the sonar system, or it may be responsible for the sensing of water streams and vibrations. 2. The posterior side wall structures. These include the following cartilaginous structures that are mostly heavily reduced or mutually fused: the cupula nasi anterior, the tectum nasi, the lamina cribrosa, the paries nasi, the commissura orbitonasalis, the cupula nasi posterior, the

    Wearing eyeglasses following nose surgery is a problem faced by many patients who require glasses for clear vision. The solutions offered for this seemingly minor problem are unsatisfactory and usually mandate special spectacle frames. We developed a simple apparatus, using a baseball cap and a tie clip, that enables suspension of eyeglasses with no pressure on the nasal bridge. This solution utilizes readily available components and maintains clear vision with possible frequent readjustment of the glasses. It also avoids contact of the glasses with any part of the face, namely the operative site, dressing, and wound discharge. We find this technique a simple and useful solution for a disturbing problem in plastic surgery.

    Non-traumatic intracranial acute epidural hematoma(EDH)is rare. It is mostly caused by coagulation disorders, dural metastasis, or vascular malformations of the dura. We report a case of non-traumatic acute EDH caused by chronic nasal sinusitis and review the literature comprising 10 cases of acute EDH caused by chronic nasal sinusitis. A 16-year-old boy visited our outpatient clinic with a 2-day history of severe headache. He did not have fever or neurological abnormalities and showed no evidence of head trauma. Cranial computed tomography(CT)revealed sphenoid sinusitis and a small amount of epidural air in the middle fossa, but no other intracranial abnormalities. After eight days with no subsequent history of trauma, radiological exams showed a massive acute epidural hematoma in the left middle fossa and temporal convexity without any vascular lesion or skull fracture. The patient underwent a hematoma evacuation that revealed neither a skull fracture nor a vascular abnormality. In this adolescent, chronic nasal sinusitis caused fragility of the meningeal artery wall, an air collection in the epidural space, and the detachment of the dura mater from the inner surface of the skull, thereby resulting in a non-traumatic acute EDH.

  6. Effect on the nasal mucosa of long-term treatment with oxymetazoline, benzalkonium chloride, and placebo nasal sprays.

    PubMed

    Graf, P; Hallén, H

    1996-05-01

    A parallel, randomized, double-blind study was performed in 30 healthy subjects to investigate the effects on the nasal mucosa of a 1-month treatment with nasal sprays. Ten subjects received oxymetazoline nasal spray; 10 subjects used a nasal spray containing the preservative benzalkonium chloride, and the others were treated with a placebo nasal spray. The three variables that were studied --nasal mucosal swelling, symptom scores, and nasal reactivity-- were estimated by histamine challenge before and after 28 days of treatment. Rhinostereometry was used to measure nasal mucosal swelling and nasal reactivity. After 28 days of use, benzalkonium chloride spray alone induced an increase in nasal mucosal swelling. At the end of the month, the score for nasal stuffiness was significantly higher for the group treated with oxymetazoline than for those treated with benzalkonium chloride. Oxymetazoline nasal spray induced a pronounced increase in nasal reactivity, which was significantly greater than that induced in the placebo group. Long-term use of placebo and benzalkonium chloride nasal sprays also caused an increase in nasal reactivity, but not to the same extent as with the nasal sprays containing oxymetazoline. The authors concluded that long-term use of oxymetazoline induces a sensation of nasal stuffiness, which may be due to unconscious exaggeration of the degree of nasal stuffiness, induced nasal hyperreactivity, or a combination of both. These factors are probably the main reasons for the prolonged use of nasal decongestive sprays and the development of rhinitis medicamentosa. Benzalkonium chloride induces mucosal swelling, which explains why the presence of this preservative in a decongestant spray aggravates rhinitis medicamentosa.

    Introduction Giant cell granuloma (GCG) is a non-neoplastic osseous proliferative lesion of unknown etiology. Although a benign disease process, GCG can be locally destructive. It is extremely rare to have a pediatric case of GCG occurring in the nasal cavity with intracranial invasion. Presentation of case We report a case of an aggressive and recurrent giant cell granuloma with intracranial invasion in a 10 years old female patient which was completely excised with endoscopic craniofacial resection. Discussion A literature review on pathogenesis, diagnosis and management is also performed. Conclusion The most common treatment for giant cell granuloma is surgery, ranging from simple curettage to resection. However, it must be completely excised in cases of aggressive and extensive lesion because of the high recurrence rate after incomplete removal. PMID:26433924

    The accuracy of the numerical result is closely related to mesh density as well as its distribution. Mesh plays a very significant role in the outcome of numerical simulation. Many nasal airflow studies have employed unstructured mesh and more recently hybrid mesh scheme has been utilized considering the complexity of anatomical architecture. The objective of this study is to compare the results of hybrid mesh with unstructured mesh and study its effect on the flow parameters inside the nasal cavity. A three-dimensional nasal cavity model is reconstructed based on computed tomographic images of a healthy Malaysian adult nose. Navier-Stokes equation for steady airflow is solved numerically to examine inspiratory nasal flow. The pressure drop obtained using the unstructured computational grid is about 22.6 Pa for a flow rate of 20 L/min, whereas the hybrid mesh resulted in 17.8 Pa for the same flow rate. The maximum velocity obtained at the nasal valve using unstructured grid is 4.18 m/s and that with hybrid mesh is around 4.76 m/s. Hybrid mesh reported lower grid convergence index (GCI) than the unstructured mesh. Significant differences between unstructured mesh and hybrid mesh are determined highlighting the usefulness of hybrid mesh for nasal airflow studies. PMID:23983811

    Despite fifty years of statistics, congresses, publications, the cleft nose remains an enigma to the great majority of cleft specialists. Most of the published papers give recipes to camouflage the cleft deformity, very few are concerned by the functional anatomy and its relation with facial growth. The complexity of the matter, the results frequently disappointing, the lack of awareness of the necessity of early nasal breathing, and the academic condemnation of any imperfect attempt to correct the nose at the time of the first operation have led to resignation. For the last forty years, we have been involved in a careful and obstinate research about the early correction of the cleft nose deformity. We wish to present our conclusions in this chapter with at least 17 years of follow-up. They are as following: in cleft patients the nasal cartilages are only deformed. We can achieve sub periosteal and sub perichondrial dissections by 6 months of age without being harmful for facial and nasal growth. Repositioning accurately the nasal structures is enough if we are able to control the healing process and prevent endonasal wound contraction. We have not to do any compromise and favor one function with regard to the others, nasal ventilation being the most important for a good facial growth. In a word, nasal pediatric surgery is necessary at the time of the first operation from 6 months of age and should be carried on with a double demand, aesthetic and functional. To achieve this goal, we must have a sound knowledge of the cleft nose deformity, of the adequate surgical techniques and of the logic chronology to reach the best result. The nose repair cannot be limited to the nasal cartilages. The whole nasal structure is concerned especially its bony framework, the width of which at the level of the piriform orifice and the nasal floor depends on the outcomes of any surgical step that it would relate to the lip, palate or alveolar closure.

    Arthroscopic rotator cuff surgery is one of the most commonly performed orthopedic surgical procedures. We conducted a study to calculate the direct cost of arthroscopic repair of rotator cuff tears confirmed by magnetic resonance imaging. Twenty-eight shoulders in 26 patients (mean age, 54.5 years) underwent primary rotator cuff repair by a single fellowship-trained arthroscopic surgeon in the outpatient surgery center of a major academic medical center. All patients had interscalene blocks placed while in the preoperative holding area. Direct costs of this cycle of care were calculated using the time-driven activity-based costing algorithm. Mean time in operating room was 148 minutes; mean time in recovery was 105 minutes. Calculated surgical cost for this process cycle was $5904.21. Among material costs, suture anchor costs were the main cost driver. Preoperative bloodwork was obtained in 23 cases, adding a mean cost of $111.04. Our findings provide important preliminary information regarding the direct economic costs of rotator cuff surgery and may be useful to hospitals and surgery centers negotiating procedural reimbursement for the increased cost of repairing complex tears.

    Chronic rhinosinusitis is a common disease which causes persisting inflammatory conditions of one or more sinuses. This study was designed to evaluate the effect of thyme honey nasal spray as an adjunctive medication on chronic rhinosinusitis after functional endoscopic sinus surgery. This was a randomized, placebo controlled, double-blind clinical study. 64 patients with chronic rhinosinusitis undergoing functional endoscopic sinus surgery were enrolled in this study. Patients were randomized and blinded to receive either placebo or thyme honey nasal spray in addition to the standard regimen postoperatively. Patients were visited on postoperative days 7, 30 and 60. The sino-nasal outcome test, endoscopic grading system and sinus CT-scan were scored before operation and on the day 60 after surgery. 54 patients completed the study. Significant improvement was observed in both treatment groups. There were no significant changes in SNOT-22, endoscopy and CT-scan scores between the two study groups. However, a greater reduction in endoscopic scores was shown in thyme honey group. The incidence of adverse effects was not significantly different between the groups, but synechiae formation and epistaxis were lower in treatment group. Thyme honey nasal spray seems to be a low-priced potential adjuvant remedy with excellent safety profile, to reduce inflammation and polyp formation and also fostering mucosal healing for patients suffering from chronic rhinosinusitis. However, further studies are recommended.

    The condition of the maxillary sinus is not routinely assessed before a Le Fort I osteotomy. Performing this procedure in an infected sinus might account for a considerable proportion of the complications, such as excessive bleeding and sinusitis. The aim of this study was to evaluate the maxillary sinus and nasal ventilation after Le Fort I osteotomy. Twenty patients were evaluated before and 2 months after surgery using validated questionnaires for sinonasal complaints (RSOM-31 and VAS score), nasal endoscopy, peak nasal inspiratory flow (PNIF), and a computed tomography (CT) scan. There were no differences in complaints before and 2 months after surgery (P>0.24). Also, the PNIF did not change significantly (P=0.10). On CT evaluation before surgery, a previously unnoted sinusitis was diagnosed in two patients. Postoperatively, a thickened sinus mucosa was present in all patients near the osteotomy line, the osteosyntheses, and around sequesters. This report describes maxillary sinus evaluation after Le Fort I osteotomy in a more comprehensive way by using CT. The Le Fort I procedure did not influence already existing physical or mental complaints, and nasal ventilation was not negatively affected. However, evaluation of sinonasal pathology should be emphasized in the preoperative work-up.

    Background The symptoms of allergic rhinitis (AR) greatly affect the quality of life (QoL) in the patients with AR. The correlations of nasal response to leukotriene D4 (LTD4) and histamine nasal provocation with health related QoL in AR are not clear. Objective To evaluate the correlations of nasal response to LTD4 and histamine nasal challenge with QoL in AR. Methods Patients randomly underwent LTD4 and histamine nasal challenge tests, completed the rhinoconjunctivitis quality of life questionnaire (RQoLQ), and rating the symptom severity score (total symptom score 4, TSS4) in the previous week. The correlations between nasal challenge tests induced nasal responses and QoL in RQoLQ were analyzed. Results A total of 25 eligible AR patients enrolled and finished both LTD4 and histamine nasal challenge and completed the questionnaire of RQoLQ. Histamine nasal challenge induced sneezing, increased nasal resistant were correlated with most of the dimensions (general, practical, nasal, eye problems, and quality of sleep, p < 0.05), while LTD4 nasal challenge induced sneeze, increased nasal resistant only correlated with nasal and ocular problems. On the contrary, the severity of the sneeze assessed by TSS4, was not correlated with QoL, while the severity of rhinorrhea, congestion, and nasal pruritus were correlated with nasal and practical problems, and nasal congestion was also correlated with ocular problems (r = 0.60, p = 0.01). Conclusion LTD4 and histamine nasal challenge induced nasal responses were correlated with different clinical symptoms severity and QoL, which can be used as a good diagnosis and evaluation methods for the management of AR.

    We used computational fluid dynamics to study the effects of the nasal cycle on the modification of unilateral nasal resistance using nasal cavity models from 2 different patients with chronic rhinosinusitis. A steady airflow field with an inspiratory flow rate of 250 mL/s was simulated using ANSYS-FLUENT v14.5. The distribution of local unilateral nasal resistance showed different shapes of variation and magnitudes of resistance depending on the distribution of cross-sectional area in the nasal cavity models. The highest local resistance on the congested side was found near the nasal valve area in the first patient, whereas the highest value was found in the nasal vestibule for the second patient. The relative importance of nasal resistance in the turbinated air passage differed for the 2 patients. The unilateral resistance of the congested state was in the range of 0.0229-0.221 Pas/mL. In the inferior meatus, greater flow rate was allowed during the congested state than during the decongested state if an extensive backflow developed.

    Nasal blockage is a common complaint in Family Practice. Decongestive nosedrops are frequently employed therapeutic measures. Due to a considerable risk of abuse and side effects, alternatives are wanted. The purpose of this study was to elucidate to what extent ENDS might represent an alternative to decongestive nose sprays (DNS). The effects of DNS (xylometazolin) and ENDS (BreatheRight) on subjective and objective nasal blockage were compared in 89 patients. Main outcome measures were recordings of nasal symptom scores on visual analogue scales (VAS), minimal cross-sectional areas (MCA) and nasal cavity volumes (NCV) as measured by acoustic rhinometry (AR), and peak nasal inspiratory flow (PNIF). ENDS significantly increased the MCA and the NCV in the anterior 0.0-3.0 cm of the nose compared to DNS, but had no effect on MCA from 3.0 to 5.4 cm behind the nostrils. In contrast to DNS, ENDS had no effect on the posterior NCV. ENDS and DNS gave comparable increase in nasal inspiratory flow as measured by PNIF, and in the subject's own experience of nasal obstruction. ENDS may represent an alternative to DNS as a measure against nasal blockage. PMID:17530269

    2014-01-01

    Midfacial degloving is a proven method for easily accessing the midface, the nasal pyramid, the maxillary and ethmoidal sinuses, the orbits, as well as the anterior skull base. Indications for this method of access mainly include tumour resections in the area of the midface, the septum, the maxillary sinus, the paranasal to the sphenoidal sinus as well as the clivus. In addition, this method of access allows for the exposure of the bony structures of the midface in the event of extensive fractures. In general, this method of access combines an incision in the oral vestibule and circular incisions in the nasal vestibule area in order to release the nasal pyramid. After removing the facial wall of the maxillary sinus, extensive exposure of the surgical site is possible. One disadvantage of this method of access is the difficult reconstruction of the nasal valve area, which often leads to cicatricial stenoses and difficulties with breathing through the nose. Furthermore, wound healing problems and osteoradionecrosis in the area of the lateral margin of the anterior nasal aperture after replantation of the facial wall of the maxillary sinus have been described, because in this area sufficient soft tissue coverage cannot be ensured when a conventional technique is used. We describe a soft tissue flap pedicled in the cranial and caudal directions in the nasal valve area which makes both the reconstruction of the nasal vestibule and sufficient soft tissue coverage of the anterior nasal aperture possible.

    The effects of nasal provocation on the rheologic properties of nasal mucus were investigated in patients with allergic rhinitis provoked by house dust. The elastic modulus (G') and the dynamic viscosity (eta') of nasal mucus were determined by an oscillating sphere magnetic rheometer. Before and after the allergen challenge, G' increased, whereas eta' decreased with increasing oscillatory frequency; these findings indicate that the nasal mucus under these conditions is a non-newtonian fluid and has the cross-linked gel-like nature typical of mucus. Both G' and eta' values after nasal provocation were significantly lower than before. The values of G' and eta' after allergen challenge were in the optimal viscoelasticity range for mucociliary transport. PMID:8476173

    The biocide triclosan is used in many personal care products, including toothpastes, soaps, clothing, and medical equipment. Consequently, it is present as a contaminant in the environment and has been detected in some human fluids, including serum, urine, and milk. Staphylococcus aureus is an opportunistic pathogen that colonizes the noses and throats of approximately 30% of the population. Colonization with S. aureus is known to be a risk factor for several types of infection. Here we demonstrate that triclosan is commonly found in the nasal secretions of healthy adults and the presence of triclosan trends positively with nasal colonization by S. aureus. We demonstrate that triclosan can promote the binding of S. aureus to host proteins such as collagen, fibronectin, and keratin, as well as inanimate surfaces such as plastic and glass. Lastly, triclosan-exposed rats are more susceptible to nasal colonization with S. aureus. These data reveal a novel factor that influences the ability of S. aureus to bind surfaces and alters S. aureus nasal colonization. IMPORTANCE Triclosan has been used as a biocide for over 40 years, but the broader effects that it has on the human microbiome have not been investigated. We demonstrate that triclosan is present in nasal secretions of a large portion of a test population and its presence correlates with Staphylococcus aureus nasal colonization. Triclosan also promotes the binding of S. aureus to human proteins and increases the susceptibility of rats to nasal colonization by S. aureus. These findings are significant because S. aureus colonization is a known risk factor for the development of several types of infections. Our data demonstrate the unintended consequences of unregulated triclosan use and contribute to the growing body of research demonstrating inadvertent effects of triclosan on the environment and human health.

  4. Heart Failure Update: Outpatient Management.

    2016-03-01

    Outpatient management of heart failure (HF) is aimed at treating symptoms and preventing hospitalizations and readmissions. Management is initiated in a stepwise approach. Blockade of the renin-angiotensin system is a cornerstone of therapy and should be started, along with beta blockers, as soon as the diagnosis of HF is made. Other drugs, including diuretics, aldosterone antagonists, hydralazine, and nitrates, may be added based on symptoms and American College of Cardiology/American Heart Association stage. Despite a great interest in and theoretical benefit of naturoceutical products in the mitigation of oxidative stress and HF progression, none has been proven to be beneficial, and concerns exist regarding their interactions with standard HF drugs. Other nonpharmacologic interventions, including sodium restriction, regular exercise, and/or cardiac rehabilitation, should be initiated at diagnosis. HF often is progressive, and clinicians should be aware of late stage management options, including implantable devices, cardiac transplantation, and hospice care. PMID:26974001

    2011-01-01

    Background: The technique of vertical dome division or tip defining, involves incising the lateral crura and vestibular skin at or lateral to the dome or tip defining point. The incision divides the lower lateral cartilage into a lateral segment and a medial segment, which are advanced anteriorly and sutured together to increase tip projection. The present study aimed at assessing a new vertical dome division, which is a modified version of vertical dome technique to decrease nasal tip projection, and increase or decrease nasal tip rotation and other tip deformities. Methods: The medical files of patients undergone rhinoplasty from 2003 to 2008 were retrospectively analyzed. The files were selected from a computerized rhinoplasty database of patients, who had been operated using a modified vertical dome technique and followed-up for one year or more after the surgery. Results: A total of 3756 patients were operated. Complications related to the nasal tip such as bossae, bifidity, persistent tip projection or tip asymmetry was seen in 81 patients (2.1%). Revisions for tip-related problems were performed in 42 patients (1.1%). Conclusions: The findings suggest that the modified vertical dome technique is an effective method for nasal tip deprojection and narrowing via an open approach. The length of follow-up and the large sample size support effectiveness of the technique. PMID:23359623

    Temporalis fascia has been used widely as a interposition graft for mucosal rotation flap in nasal septal perforation repair. However, the exact role of temporalis fascia in healing process has not yet been clarified. For the pedicle of rotation flap has been considered as a major vehicle for nutrition distribution, the role of temporalis fascia has been devaluated. In this study, we experienced small nasal septal perforation repairs using free mucosal graft not having pedicles but covered by temporalis fascia. Three patients with small nasal septal perforations not larger than 1 × 1 cm were included. In 2 patients, the perforations were repaired using free composite grafts from the inferior turbinate mucosa covered by continuous temporalis fascia not divided, and the surgical results were successful with complete healings. In 1 patient, however, the temporalis fascia was divided into 2 parts to better fit the shape of the perforation, and the graft failed to survive. These surgical results suggest that the temporalis fascia might have an important role in healing process of nasal septal defect and could be used as a beneficial options for small mucosal defect repair surgeries using free mucosal grafts.

    We present a review of international literature on the topic of nasal dorsum reconstruction with 11th rib cartilage and auricular cartilage grafts, analyzing 123 patients selected from 653 cases of rhinoplasties performed between January 1990 and October 2007 at the Department of Plastic and Reconstructive Surgery of the University of Rome "Tor Vergata." We present our experience with the correction of deformities of the nasal dorsum using rib cartilage and auricular cartilage grafts. The majority of the time, nasal dorsum deformities are complicated defects to correct surgically. They can be a consequence of naso-ethmoid-orbital fractures and of surgical procedures in the nasal area where a loss of bone or septal cartilaginous support has occurred. After a review of the techniques employed in the reconstruction, we describe the advantage of the use of rib cartilage and our experience using this procedure. In the sample examined, 84% of treated patients showed cosmetic improvements, with satisfactory results to both surgeon and patient. A functional improvement has been achieved in 94% of the operated cases. PMID:19131722

    Histamine, norepinephrine and serotonin were assayed and localized by fluorescence histochemistry in normal mucosa and nasal polyps because of their possible role in the development of inflammation and edema. Histamine was present in greater concentration in nasal polyps than in normal mucosa. Norepinephrine was present primarily in the base of nasal polyps and in greater concentration than in normal mucosa. Patients with aspirin sensitivity and asthma had much lower histamine concentrations in their nasal polyps than all other patients with nasal polyps. A proposal for a possible mechanism of formation of nasal polyps based on vascular and inflammatory mechanisms and incorporative roles for histamine and norepinephrine is presented.

    Several microbes, including Staphylococcus epidermidis (S. epidermidis), a Gram-positive bacterium, live inside the human nasal cavity as commensals. The role of these nasal commensals in host innate immunity is largely unknown, although bacterial interference in the nasal microbiome may promote ecological competition between commensal bacteria and pathogenic species. We demonstrate here that S. epidermidis culture supernatants significantly suppressed the infectivity of various influenza viruses. Using high-performance liquid chromatography together with mass spectrometry, we identified a giant extracellular matrix-binding protein (Embp) as the major component involved in the anti-influenza effect of S. epidermidis. This anti-influenza activity was abrogated when Embp was mutated, confirming that Embp is essential for S. epidermidis activity against viral infection. We also showed that both S. epidermidis bacterial particles and Embp can directly bind to influenza virus. Furthermore, the injection of a recombinant Embp fragment containing a fibronectin-binding domain into embryonated eggs increased the survival rate of virus-infected chicken embryos. For an in vivo challenge study, prior Embp intranasal inoculation in chickens suppressed the viral titres and induced the expression of antiviral cytokines in the nasal tissues. These results suggest that S. epidermidis in the nasal cavity may serve as a defence mechanism against influenza virus infection.

    We evaluated a commercial multiplex polymerase chain reaction (PCR) assay in a cross-sectional study among 81 adult and pediatric outpatients-40 cases with upper respiratory infection symptoms and 41 asymptomatic controls-from February to April 2008. Two specimens (throat swab and nasal swab) from each participant were tested using the EraGen MultiCode-PLx Respiratory Virus Panel that detects 17 viral targets. Throat swabs were also tested for Group A Streptococcus (GAS) by PCR. Respiratory viruses were detected in 22/40 (55%) cases and in 3/41 (7%) controls (P < 0.001). GAS was detected in 10 (25%) cases; GAS and respiratory virus co-infection was found in 4 (10%). Agreement between nasal and throat swabs for viral detection was 69% in cases and 95% in controls. Of 22 cases with a detectable virus, 12 (54%) were picked up by only 1 (throat or nasal) specimen, and the detection rate was increased by combining results of nasal and throat swab testing.

    The objective of this study was to examine the effects of nasal passage characteristics on anterior particle deposition during cyclical breathing. Forty healthy, nonsmoking, adult subjects participated in this study. Nasal passage characteristics such as nostril length, width, angle, ellipticity, and minimum nasal cross-sectional area were measured. The subjects inhaled a polydisperse radioactively tagged aerosol (mass median aerodynamic diameter = 5.4 microns, geometric standard deviation [GSD] = 1.3) into the nose and exhaled through the mouth. The amount of radioactivity in the nose was measured immediately after inhalation and thereafter for 54 minutes. At 52.5 minutes, subjects wiped the accessible portion of the anterior nose to remove any remaining activity. The difference in activity at 52 and 54 minutes was used as a measure of activity removed during the nose wipe. Percentage of activity in the nasal passage at 52 minutes and percentage of activity removed with the nose wipe were considered surrogates for particles deposited in the anterior nasal passage. A multiple regression analysis showed that the degree of ellipticity of the nostrils was significantly related to particle deposition in the anterior nasal passage. These results suggest that ellipticity of the nostrils may be a determinant of the amount of particle deposition in the anterior nasal passage.

    Nasal airflow is greater in one nostril than in the other because of transient asymmetric nasal passage obstruction by erectile tissue. The extent of obstruction alternates across nostrils with periodicity referred to as the nasal cycle. The nasal cycle is related to autonomic arousal and is indicative of asymmetry in brain function. Moreover, alterations in nasal cycle periodicity have been linked to various diseases. There is therefore need for a tool allowing continuous accurate measurement and recording of airflow in each nostril separately. Here we provide detailed instructions for constructing such a tool at minimal cost and effort. We demonstrate application of the tool in 33 right-handed healthy subjects, and derive several statistical measures for nasal cycle characterization. Using these measures applied to 24-hour recordings we observed that: 1: subjects spent slightly longer in left over right nostril dominance (left = 2.63 ± 0.89 hours, right = 2.17 ± 0.89 hours, t(32) = 2.07, p < 0.05), 2: cycle duration was shorter in wake than in sleep (wake = 2.02 ± 1.7 hours, sleep = 4.5 ± 1.7 hours, (t(30) = 5.73, p < 0.0001). 3: slower breathing was associated with a more powerful cycle (the extent of difference across nostrils) (r = 0.4, p < 0.0001), and 4: the cycle was influenced by body posture such that lying on one side was associated with greater flow in the contralateral nostril (p < 0.002). Finally, we provide evidence for an airflow cycle in each nostril alone. These results provide characterization of an easily obtained measure that may have diagnostic implications for neurological disease and cognitive state. PMID:27711189

    Nasal polyps (NPs) are benign lesions of nasal and paranasal sinuses mucosa affecting 1-4 % of all adults. Nasal polyposis affects the quality of patient's life as it causes nasal obstruction, postnasal drainage, purulent nasal discharge, hyposmia or anosmia, chronic sinusitis, facial pain and snoring. Without treatment, the disease can alter the craniofacial skeleton in cases of extended growth of polyps. The development of NPs is caused by the hyperplasia of nasal or paranasal sinuses mucosa, and edema of extracellular matrix. This is usually the result of high concentration of high molecular mass hyaluronan (HA) which is either overproduced or accumulated from blood supply. The size of HA presents high diversity and, especially in pathologic conditions, chains of low molecular mass can be observed. In NPs, chains of about 200 kDa have been identified and considered to be responsible for the inflammation. The purpose of the present study was the investigation, in NPs and normal nasal mucosa (NM), of the expression of the wild-type and alternatively spliced forms of hyaluronidases, their immunolocalization, and the expression of HA synthases to examine the isoform(s) responsible for the increased amounts of HA in NPs. Hyaluronidases' presence was examined on mRNA (RT-PCR analysis) and protein (immunohistochemistry) levels. Hyaluronan synthases' presence was examined on mRNA levels. Hyaluronidases were localized in the cytoplasm of epithelial and inflammatory cells, as well as in the matrix. On mRNA level, it was found that hyal-1-wt was decreased in NPs compared to NM and hyal-1-v3, -v4 and -v5 were substantially increased. Moreover, HAS2 and HAS3 were the only hyaluronan synthases detected, the expression of which was almost similar in NPs and NM. Overall, the results of the present study support that hyaluronidases are the main enzymes responsible for the decreased size of hyaluronan observed in NPs; thus they behave as inflammatory agents. Therefore, they

    A bilateral nasal phaeohyphomycotic infection caused by Bipolaris hawaiiensis in an immunocompromised woman from India is described. Repeated direct microscopic examinations of the nasal scrapings revealed the presence of septate, branched, pigmented hyphal fragments intermingled with cells that divided internally by one transverse septum and a few cells that were chestnut brown dividing internally by septa in different planes to become muriform. Cultures of the scrapings yielded B. hawaiiensis. Local excision of the crusted lesion followed by application of 0.03% nystatin solution four times a day for 3 weeks cured the infection.

Aspirin was well absorbed following nasal administration of a neutralized, nonirritating solution containing triethanolamine. The rate of absorption was slower than that of other nasally administered drugs, such as propranolol or progesterone. The bioavailability of aspirin following nasal administration was 100%, whereas the oral bioavailability was only 58.8% at the dose studied. PMID:1501071

Infrequent case reports of extra-pleural SFTs have been described at various sub sites within the head and neck area. We report a case of recurrent sino-nasal SFTs treated with surgery followed by re-excision and adjuvant radiation on recurrence and then salvage chemotherapy on progression. Further discussed are the challenges associated with accurate histological and immunohistochemical diagnosis, the difficulty in assessing the aggressiveness and malignant potential of these lesions and the appropriate treatment and follow-up duration that these neoplasms require. To the best of our knowledge this is the first reported case of recurrent malignant sino-nasal SFT in available scientific literature in English language.

    A solitary fibrous tumour (SFT) is a rare tumour that originates from the mesenchyme and arises mainly in the pleura. In this report, we present a rare case of a 77-year-old man with a SFT in the left nasal cavity. On CT and MRI, a large mass is seen in the left nasal cavity, extending to the choana. The mass was radically resected via functional endoscopic sinus surgery (FESS). Histological examination showed a fibroblastic mesenchymal tumour with a prominent hemangiopericytic vascular branching pattern that stained diffusely positive for the immunohistochemical markers CD34, Bcl-2, and CD99, which was compatible with the histopathological diagnosis of a SFT. Imaging and histological features are discussed, along with the reports in literature, clinical management, and follow-up of this pathology.

    Objectives MRSA poses a considerable public health threat to the community. The objectives of this study were to assess the prevalence of MRSA carriage and determine factors that were associated with MRSA carriage among outpatients who had used antibiotics in the previous three months and who lived in a high-density livestock farming area along the Dutch-German border. Methods Cross-sectional prevalence study carried out between November 2011 and June 2012. Nasal swabs and questionnaires were collected in patients (>4 years) who had used antibiotics in the previous three months from twelve Dutch General Practitioners (GPs), seven German GPs and two German outpatient urologists. To assess nasal carriage, swabs were analyzed using selective MRSA agars after broth enrichment. MRSA positive samples were spa typed. Results Data were collected from 513 GP outpatients in the Netherlands, 261 GP outpatients in Germany and 200 urologist outpatients in Germany. The overall prevalence of MRSA carriage was 0.8%, 1.1% and 2.0%, respectively. In the GP outpatient populations, the prevalence was similar in both countries (0.8% and 1.1%, respectively, p = 0.879), all spa types were indicative for livestock-associated MRSA (4xt011 in the Netherlands; 2xt034 and t011 in Germany) and being a farmer, living on or near (<5km) to a farm were associated with MRSA carriage. In the urologist outpatient population, the prevalence was higher (2.0%), all spa types were indicative for healthcare-associated MRSA (t068, t032, t003, t10231) and being a farmer, living on or near to a farm were factors not associated with MRSA carriage. Conclusions The prevalence of MRSA carriage in these community outpatient populations along the Dutch-German border was low. There were striking similarities in livestock-associated MRSA carriage and clonal spread in the outpatient populations seeing their GP in both countries. In contrast, urologist outpatients in Germany were colonized with spa types indicative of

    2015-06-01

    Heinrich von Pfalzpaint (circa 1415-1465) was a Bavarian military surgeon of the Teutonic Order who treated more than 4000 casualties during the siege of Marienberg Fortress (1454-1457). In 1460, he reported "How to create a new nose if it has been chopped off and the dogs have eaten it" in his treatise on wound care Bündt-Ertznei. He used opium-soaked sponges for anesthesia, described the surgical extraction of bullets and cleft lip repair. Pfalzpaint would have been the first author to describe nasal reconstruction in Europe if his treatise had not been lost. Only 5 copies of his manuscript existed. One was rediscovered and printed in 1868. Pfalzpaint's technique for nasal reconstruction was performed in 2 stages using an undelayed skin flap from the upper arm, which was sutured to the nasal defect and the arm was bandaged to the head. After 8 to 10 days, he divided the pedicle; inset the flap; and fashioned the nasal dorsum, alae, and columella. Tagliacozzi described arm flap nasal reconstruction more than a century later in 1597. He used delayed skin flaps, with at least 6 operative stages over 4 months. Pfalzpaint was ahead of his time regarding his knowledge of wounds, insistence on surgical cleanliness, and his technically easier arm flap rhinoplasty, compared with Tagliacozzi. Pfalzpaint, who is rarely referenced in the literature, should be remembered as a great pioneer of reconstructive surgery in Europe. PMID:26080150

    Study Design Prospective comparative study. Purpose To compare the incidence and severity of adverse reactions associated with myelography performed in outpatients vs. in inpatients and report the safety and usefulness of outpatient myelography in Japanese patients. Overview of Literature Myelography is normally performed as an inpatient procedure in most hospitals in Japan. No studies have reported the usefulness and adverse effects of outpatient myelography in Japanese patients. Methods We performed 221 myelography procedures. Eighty-five of the 221 patients underwent outpatient myelography using our new protocol. The incidence and severity of adverse reactions were compared with the other 136 patients, who underwent conventional inpatient myelography. We further compared the cost of outpatient and inpatient myelography. Results The overall rate of adverse effects was 9.4% in outpatients, as compared with 7.4% in inpatients. Overall, 1.2% of outpatients and 0.74% inpatients experienced "severe" adverse effects (requiring hospitalization). There were no significant differences between the 2 groups in either the overall rate of adverse effects or the rate of "severe" adverse effects. Moreover, the average outpatient procedure cost was only one-third to one-half that of the inpatient procedure. Conclusions This was the first study to address the safety and usefulness of outpatient myelography in Japanese patients. If selected according to proper inclusion criteria for outpatient procedure, no significant differences were observed in the adverse effects between inpatients and outpatients. The outpatient procedure is more economical and has the added benefit of being more convenient and time-efficient for the patient. PMID:26713127

    This article analyzes the legal and therapeutic jurisprudence considerations raised by outpatient commitment. Although older forms of outpatient commitment have both legal and therapeutic advantages, preventive outpatient commitment raises serious legal problems and potential antitherapeutic consequences that may outweigh its claimed therapeutic value. As a result, alternatives are proposed, including wider availability of community treatment and outreach and case management services, assertive community treatment, police and mental health court diversion programs, and creative uses of advanced directive instruments and behavioral contracting. Proposals also are made for how preventive outpatient commitment can be applied more therapeutically, including hearings that accord patients a sense of procedural justice and techniques designed to motivate individuals facing such hearings to agree to accept treatment voluntarily.

    Background Primary human airway epithelial cells, when submerged in culture, undergo a dedifferentiation with loss of many features of the in vivo airway epithelium. However, when cultured in an air-liquid interface (ALI), cells develop a well-differentiated, polarized, and pseudostratified epithelium. The aim of the current study was to characterize the mucociliary differentiation of human nasal mucosa and polyp epithelial cells cultured using an ALI system. Methods Nasal mucosa (NM, n = 3) and nasal polyps (NP, n = 3) were obtained from patients undergoing nasal corrective surgery and endoscopic sinus surgery, respectively. Epithelial cells were obtained from the explant method, and differentiated in ALI culture during 28 days. Cultures were studied at different time points (0, 7, 14, 21, and 28 days): tissue ultrastructure by scanning electron microscopy (SEM) and transmission electron microscopy (TEM); mucous (MUC5AC, MUC5B) and serous (lactoferrin) cell secretion by ELISA; and cytokeratin 18 (epithelial marker), β-tubulin IV (cilia marker), MUC5AC (goblet cell marker), and p63 (basal cell marker) expression by immunocytochemistry. Results In both NM and NP ALI cultures and at days 14 and 28, a pseudostratified epithelium with ciliated, mucus-secreting and basal cells was observed, and expression of cytokeratin 18, b-tubulin IV, MUC5AC and p63 was detected. In NP cultures, both MUC5AC (day 14: 2.2 ± 0.1-folds; day 28: 3.6-fold ± 0.7-fold) and MUC5B (day 14: 3.2-fold ± 0.6-fold; day 28: 3.1-fold ± 1-fold) increased over time compared to day 0 (P < 0.05). In NM cultures, only MUC5B (day 14: 3.9-fold ± 0.9-fold; day 28: 3.4-fold ± 0.4-fold; P < 0.05) but not MUC5AC increased over time compared to day 0 (P < 0.05). Secretion of lactoferrin was present but showed no changes over time in either NM or NP ALI cultures. Conclusions Epithelial cell ALI cultures provide a well-differentiated human nasal mucosa and polyp tissues that may be used as an in vitro model

    Introduction: Investigators believe that anatomical abnormalities in the sinonasal region can be the cause of some chronic and refractory headaches that may respond well to surgical intervention. This study presents the prevalence of headache in patients with nasal septal deviation and their response to surgical treatment over a 2-year follow-up period. Materials and Methods: This descriptive and prospective study was conducted on 98 patients with nasal septal deviation who underwent septoplasty surgery in the Imam Hospital in Ahwaz. Preoperative information was acquired by asking the patients and by completing SNOT-20 questionnaires by patients. After the surgery, information about changes in the quality of headache in patients with dominant contact points in preoperative nasal endoscopy whose headache responded to topical anaesthesia with lidocaine 2%+naphazoline 0.5% was collected over a 2-year follow-up. Final data were analyzed by SPSS and descriptive statistics. Results: Ninety-eight patients were studied, comprising 58.2% men and 41.8% women. They ranged in age between 18 and 46 years (mean=24). Nasal obstruction (72.4%), snoring (58.1%), headache (46%) and epistaxis (17.3%) were the most frequent preoperative symptoms. The most common site of the headache was the frontal region (68.8%). Patients' headache was bilateral in 71.1% of cases. In 82.2% of patients, headache lasted less than four hours a day. The headache was pulsatile in 53.3%, sharp in 31.2% and compressive in 15.5% of cases. In the post-operative assessment, despite gradual decline in the referral patients for follow-up, a notable and gradual recovery in patients’ headache was seen with 82.8% of the patients reporting complete or partial recovery of the headache at the end of the 2-year follow-up. Conclusion: Headache is one of the most common symptoms in patients with nasal anatomical abnormalities such as septal deviation and usually responds well to surgical treatment. More studies with

    Background: To retrospectively study the costochondral graft (CCG) based nasal dorsum augmentation failures due to warping. Materials and Methods: All patients fulfilling inclusion and exclusion criteria between January 2008 and December 2011 were included in the study. The details of the dorsal nasal length (DNL) immediate postoperative and 1 week postoperative period as well as the degree of divergence from midline by warping noted down in mm along with age, gender, and nature of graft. Statistics: Data analyzed using Statistical Package for the Social Sciences version 17. Descriptive statistics, Chi-square test and one-way analysis of variance are presented. P value ≤0.05 was considered significant. Result: One hundred and fifty seven cases fulfilled the criteria. Of these, 44 (28%) were males and rest were females. The mean age of the patients was 24.41 ± 4.9 years with a range of 17-37 years. In 102 cases (65%) had soft CCG while 55 (35%) were identified to be gritty type of CCG. Of the 157 cases, warping was identified in 41 cases (26.1%) and required revision of the surgery. Age group was significantly associated with presence of warping (P = 0.000). Discussion: With increase in age, the number of patients with gritty CCG was higher. Older patients had lesser incidence of warping while younger patients had more incidence of warping. The incidence was not significantly related to gender or the DNL. The grafts that were relatively straight had less incidence of warping. PMID:23662254

Ever-use of nasal snuff was associated with an odds ratio (OR) for nasal cancer of 1.45 (95% confidence interval [CI] 0.88–2.38) in the total study population, whereas OR in smokers was 2.01 (95% CI 1.00-4.02) and in never smokers was 1.10 (95% CI 0.43–2.80). The OR in ever-smokers vs. never-smokers was 1.60 (95% CI 1.24–2.07), with an OR of 1.06 (95% CI 1.05–1.07) per pack-year smoked, and the risk was significantly decreased after quitting smoking. Exposure to hardwood dust for at least 1 year resulted in an OR of 2.33 (95% CI 1.40–3.91) in the total population, which was further increased in never-smokers (OR 4.89, 95% CI 1.92–12.49) in analyses stratified by smoking status. The OR for nasal cancer after exposure to organic solvents for at least 1 year was 1.53 (1.17–2.01). Ever-use of nasal sprays/nasal lavage for at least 1 month rendered an OR of 1.59 (1.04–2.44). The OR after use of insecticides in homes was 1.48 (95% CI 1.04–2.11). Conclusions Smoking and exposure to hardwood dust were confirmed as risk factors for nasal carcinoma. There is evidence that exposure to organic solvents, and in-house use of insecticides could represent novel risk factors. Exposure to asbestos and use of nasal snuff were risk factors in smokers only. PMID:23130889

    A randomized double-blind parallel study with 20 healthy volunteers was performed to examine the effect of oxymetazoline nasal spray on the development of rhinitis medicamentosa. For 30 days, 10 subjects were given oxymetazoline nasal spray once daily at night and placebo in the morning and at noon, while the others used oxymetazoline nasal spray three times daily. Before and after the course of treatment, the mucosal surface positions were determined with rhinostereometry, followed by histamine challenge tests. In the morning and the evening just before use of the nasal spray, symptoms of nasal stuffiness were evaluated on visual analogue scales (0-100). After 30 days, rebound swelling and nasal stuffiness were found in both groups. In the group receiving oxymetazoline nasal spray once daily at night, the mean rebound swelling was 0.8 mm (p < 0.01) and the estimated mean symptom score for nasal stuffiness in the evening was 43 (p < 0.05). In the group receiving the same nasal spray three times daily, the mean rebound swelling was 1.1 mm (p < 0.01) and the mean evening symptom score was 43 (p < 0.05). The finding of an increase in histamine sensitivity in both groups was taken to indicate nasal hyperreactivity. There was no significant difference in the investigated variables between the two groups. It is concluded that the risk of developing rebound swelling and nasal hyperreactivity remains, whether oxymetazoline nasal spray is used once or three times a day for 30 days.

    Nasal structural reconstruction is a formidable task in cases where there is loss of support to both the nasal dorsum and tip. A multitude of surgical approaches and materials have been used for the correction of the saddle-nose deformity with varying degrees of success. Articulated irradiated rib cartilage inserted through an external rhinoplasty approach was used to reconstruct nasal deformities in 18 patients over a 6-year period. Simultaneous use of a midline forehead flap to reconstruct the overlying soft tissue was required in four cases. Follow-up ranged from 1 to 6 years (mean, 2.8 years). Results were rewarding in most cases with marked improvement in nasal support and airway. Revision and/or replacement secondary to trauma or warping of the graft was required in four cases. None of the patients exhibited infection, extrusion, or noticeable resorption. A description of the surgical technique, review of all the cases, and recommendation for continued use of this graft material are discussed.

    Although discussions regarding nasal packing are still ongoing, to eliminate any possible complications, surgeons have used nasal packing for many years. Septoplasty is one of the most frequently performed operations by head and neck surgeons. Any methods to diminish the surgical time or bring comfort to the surgeon will be well appreciated. In this study, we attempted to demonstrate the usefulness of the stapler method by comparing preoperative and postoperative results from the visual analog scale (VAS), nasal obstruction symptom evaluation (NOSE), rhinosinusitis quality of life questionnaire (RQLQ), and acoustic rhinomanometry values. In addition, we evaluated pain scores, postoperative complications, and breathing after nasal packing, stapling, and trans-septal suturing techniques. Patients were divided into three groups. In the first group, deviated cartilage was removed or repositioned and mucoperichondrial flaps were closed with a bioresorbable stapler after septoplasty. Four or five staples were placed on the septum. In the second group, the septum was sutured continuously with 4/0 Pegelak (Doğsan TR). In the third group, Merocel packs were used without any sutures and were kept for 48 h. Nasal packing leads to patient discomfort after septal surgery; however, there is no difference in patient comfort between closing the mucoperichondrial flaps by suturing the septum or using a stapler. After surgery, there were no differences between the groups in terms of successful breathing. This situation was assessed by endoscopic examination and acoustic rhinomanometry. Thus, there was no objective or subjective difference. Stapling increases the doctor's comfort level and surgical time is optimized. Although experienced surgeons can easily suture the septum, less experienced ones have some difficulty; therefore, stapling may provide more benefit to the latter. Further, four staples are sufficient to close the septum.

    In this paper, we present the results of coblation nasal septal swell body (NSB) reduction for the treatment of nasal obstruction in patients with abnormally thickened NSB. The study design was a retrospective clinical series conducted at a single tertiary medical center. Eight patients underwent coblation NSB reduction. Pre-operative and post-operative nasal functions were evaluated by acoustic rhinometry and subjective symptom scales. We also analyzed pre-operative CT scan images and nasal endoscopic findings. The mean maximal NSB width was 16.4 ± 2.2 mm on pre-operative coronal CT scan images. The mean visual analog scale score for nasal obstruction was decreased from preoperative 7.63 ± 0.99 points to 3.88 ± 0.92 points (postoperative 3 months), 4.16 ± 0.78 points (postoperative 6 months), and 4.63 ± 0.69 points (postoperative 1 year). Six out of the eight patients were satisfied with the clinical outcome at 1 year after the procedure. To the best of our knowledge, coblation NSB reduction has not yet been reported in the medical literature. Our results show that it can be an effective treatment modality for nasal valve narrowing in patients with abnormally thickened NSB.

  7. Effect of environmental contaminants on nasal lysozyme secretions.

    PubMed

    Human nasal secretions are comprised of lysozyme and albumin as their main protein components. Lysozyme, an anti-microbial substance, is produced by nasal serous cells while albumin is obtained, primarily, from increased nasal vasculature permeability. We measured lysozyme levels in nasal secretions following challenge by a variety of non-infectious environmental contaminants. The methodology given presents a simple and rapid method of collecting nasal secretions and determining their lysozyme content, a technique which can be used for a host of environmental irritants.

    Nasal furunculosis is a deep infection of hair follicle within the nasal vestibule. In this report, the authors presented a 49-year-old woman with 4-day history of focal red area and tender swelling on the tip of her nose. On physical examination, together with a swelling at nasal vestibulum, erythema, and edema on the skin of nasal tip were observed, which is called the Rudolph Sign. The patient was treated with intranasal topical mupirocin and oral sodium fusidate. Because nasal furunculosis may lead to serious complications such as ophthalmic vein thrombosis and cavernous sinus thrombosis, early diagnosis and effective treatment is essential. PMID:26335324

    Nasal bone fractures are the most common among facial fractures. Usually these are adequately treated with closed reduction and internal and/or external stabilization with splints. However, there are clinical situations where the nasal bones are severely displaced, the nasal septum fractured and displaced, or there are external drape lacerations which preclude the use of nasal splints. If the nasal bones are reducible but unstable we consider them “flail” and in this case transmucosal, endonasal Kirschner wires are used for dorsal support until sufficient healing occurs. The technique is simple, quick, and predictable and causes minimal discomfort to the patients. PMID:23730426

    Pleomorphic adenoma is the most common benign tumor of the salivary glands. A 62-year-old female patient presented with epiphora and was suffering from breathing difficulties. With the diagnostic nasal endoscopy, a mass, originating from right inferior nasal turbinate and filling the entire nasal cavity, was seen. Originating from the inferior nasal turbinate is a very rare entity. Paranasal sinus computed tomography and magnetic resonance images revealed a mass that fills and expands the right nasal cavity. Mass was hypoechoic in B-mode ultrasonography and hypovascular in color Doppler ultrasonography, and rate of tissue stiffness was high in sonoelastography. These were helpful for the diagnosis.

    Background: Acquired nasal stenosis poses a reconstructive challenge for the facial plastic surgeon. Many surgical options are available, ranging from primary closure to skin grafts to free flap reconstruction for complex defects. The free auricular composite graft is a single-stage procedure that can be used to repair nasal vestibular stenosis causing nasal obstruction. Case Report: We present the case of a patient with acquired nasal stenosis as a result of prolonged nasal tampon placement secondary to severe epistaxis and subsequent nasal vestibular infection. Repair via auricular composite graft was successful, and we provide a thorough explanation of graft design and operative technique. Conclusion: Free auricular composite grafts can produce desirable functional and aesthetic outcomes and should be considered in patients presenting with acquired nasal stenosis. PMID:27303225

    The literature suggests that outpatient tonsillectomy in children is a safe and cost-effective procedure. These conclusions have been based on the low rate of post-operative complications. Recent papers suggest contra-indications for ambulatory surgery in some patients. A retrospective study involving 311 children was performed in our Department. We defined two groups in which the out-patient policy had failed. The first group (43 children) comprised inpatient children scheduled because of an unhealthy preoperative state (12 patients), a sleep-apnea syndrome (5 children), a major associated procedure (3 patients), a social or family environment not reliable enough for postoperative supervision (19 patients) or because of parental refusal (4 patients). The second group (268 patients) was constituted of scheduled outpatients. In this group, the outpatient policy failed in 31 and children had to be kept overnight, because complications occurred. The main short-term complication was bleeding (13 patients). In 8, delayed complications were observed. Thus, according to the literature, children with concomitant heavy medical problems or with a poor social environment have to be managed as inpatients. For the others outpatient procedures were possible but parents should previously be informed of the possible overnight hospital supervision which is needed in 11.6% of cases. When comparing the youngest patients under 4 years of age with the others, although the preexisting medical and social conditions are important factors that may contraindicate ambulatory surgery, once the latter has been decided on, there is no significant difference between the two age groups regarding the number of children requiring overnight hospital supervision.

    This is a report of a pilot program for laparoscopic sterilization with emphasis on surgical and anesthetic technics. In 1971 the program was developed at the North Carolina Memorial Hospital. Subjects were 129 private patients, mostly white, of middle income with 2 or more children, and from 19 to 47 years of age. Follow up of over 90% indicated high patient satisfaction. Complications were few but may occasionally require surgical management and the method should not be considered a minor procedure. At first patients were handled as inpatients for 1 day preceding surgery. Later an outpatient status was adopted. At an earlier visit a history is taken, instructions given by a nurse, the assigned physician (who may be a physician in training) reviews the history, performs a physical examination, and explains the operation to both the patient and her husband. Laboratory work is performed, operative permits are signed, and patients are asked at this time to agree to sterilization by laparotomy if the laparoscopic approach proves infeasible. On the morning of surgery suitable intravenous medication (Valium 5 mg), fentanyl, and atropine are given and followed by pure oxygen inhalation for 3-5 minutes. Pentothal followed by succinylcholine are given and the patient intubated. Anesthesia is maintained by succinylcholine drip and inhalation of nitrous oxide and oxygen. After surgical preparation with Betadine solution, a combination tenaculum-sound is placed in the cervical canal. Pneumoperitoneum is established with carbon dioxide gas through a Verres needle inserted through a small subumbilical incision. The laparoscopic trocar is introduced by enlarging the same incision. After inspection a second 6 mm trocar is inserted just about the tubes and biopsy forceps introduced. The tenaculum in the cervix is used to position the uterus and tubes. After cauterization tubes are divided with the biopsy forceps and a biopsy specimen obtained if possible without undue action on

    Introduction: Streptococcus pneumoniae in asymptomatic manner colonize the mucous membranes of the nasopharynx of children and adults, but can cause serious illness in the media which are naturally sterile. In 5-40% of healthy population this bacteria colonize the nasopharyngeal mucosa thanks to the surface adhesin protein, which allow the bacteria to attach to the epithelial cells. The normal nasopharyngeal microflora retains pneumococcus in a small number and does not allow it to express its pathogenic potential and cause disease. If this dominance of the normal microflora is violated, after adherence and local duplication, pneumococcus can spread to the middle ear, sinuses or lungs. Colonization is more common in children than in adults. Goal: The goal of this study was to determine the prevalence of the carrier state and susceptibility of pneumococcal strains that circulate in the outpatient population of Sarajevo Canton as a potential source of infection. Material and methods: In the microbiological laboratory of the Institute of Public Health of Canton Sarajevo in the period from July 1, 2013 until April 15, 2014 were analyzed swabs of the nose and nasopharynx, eye and ear from a total of 4109 outpatients. Swabs were inoculated on blood agar nutrient medium. Then was performed catalase test, preparation by Gram and susceptibility test on Optochin. Isolates positive for S. pneumoniae were subjected to in vitro assays to investigate the antimicrobial susceptibility/resistance. Results: Out of 4109 analyzed swabs the pneumococcus positive was 180 (4.38%). Of these, 137 (76.11%) nasal and nasopharyngeal swabs, 33 (18.33%) of the eyes and 10 (5.56%) ear. The highest number of positive swabs were isolated in children aged 6 years and less, a total of 168 (93.33%), in children aged 7-13 years were positive 7 (3.89%), while among respondents aged 14-20 years only 5 (2.78%). Conclusions: The most common site for isolation of pneumococci is the nose and throat, and the

    Although autologous fat injection into the face is a widely used procedure in aesthetic surgery, heed must be taken because it may cause severe complications related to inadvertent arterial embolization, including stroke and vision loss. Vision loss may originate from ophthalmic artery occlusion, and no therapeutic options have yet been reported for this condition. Herein, the authors report a case of ophthalmic artery occlusion following nasal autologous fat injection. Partial recovery of choroidal and retinal perfusion, ocular motility, and corneal clarity was achieved after intraarterial pharmacomechanical thrombolysis. PMID:21185202

    The authors describe studies showing the effectiveness of involuntary outpatient commitment in improving treatment compliance, reducing hospital readmission, and reducing episodes of violence among persons with severe psychiatric illnesses. They point out that because of its role in enhancing compliance with treatment, outpatient commitment can be regarded as a form of assisted treatment, such as assertive case management, representative payeeship, and mental health courts. The authors argue that such assisted treatment is necessary for persons with severe psychiatric illnesses who are noncompliant with their medication regimens because many lack awareness of their illnesses because of biologically based cognitive deficits. They recommend outpatient commitment for any individual with a severe psychiatric disorder who has impaired awareness of his or her illness and is at risk of becoming homeless, incarcerated, or violent or of committing suicide, and they provide case examples. The authors conclude by addressing eight of the most common objections to outpatient commitment by mental health professionals and civil liberties groups that oppose outpatient commitment.

    Methicillin-resistant Staphylococcus aureus (MRSA) colonized children are at an increased risk of developing infections than methicillin-sensitive S. aureus colonized children. Nasal specimens from inpatient children, mothers of inpatient children, healthcare workers, and outpatient children at Tripoli Children Hospital (TCH) were examined for MRSA by chromogenic MRSA ID medium. Susceptibility of MRSA isolates to antibiotics was determined by the disc diffusion method. The nasal carriage rate of MRSA among inpatient children (8.3%, 24 of 289), their mothers (11%, 22 of 200), and healthcare workers (12.4%, 22 of 178) was significantly higher than among outpatient children (2.2%, 2 of 91) (P < 0.05, P < 0.02, and P < 0.006, respectively). Of the examined MRSA isolates (N = 35) 10 (28.6%) were positive for Panton-Valentine leucocidin genes by polymerase chain reaction. Multidrug resistance was found in 24.3% (17 of 70) of MRSA isolates. Nasal carriage of multidrug-resistant Panton-Valentine leucocidin-positive MRSA is not uncommon among inpatient children and their mothers in Tripoli.

    Intranasal corticosteroid therapy has exhibited effectiveness for improving nasal symptoms and quality of life (QOL) scores associated with seasonal allergic rhinitis. We prospectively investigated the efficacy of mometasone furoate nasal spray (MFNS) for improving the total nasal symptom score, QOL score, and sleep quality in subjects with perennial allergic rhinitis (PAR). Nasal airway conditions were also objectively assessed by measuring nasal nitric oxide (NO). Fifty-seven patients with PAR were randomized to MFNS or placebo for a 14-day, double-blind, crossover study. The subjects recorded their symptoms on nasal symptom forms and a visual analog scale. QOL and sleep quality were surveyed in accordance with the Japanese version of the Rhinoconjunctivitis Quality of Life Questionnaire (JRQLQ) and the Japanese version of the Epworth Sleepiness Scale. Nasal NO was measured during a single exhalation using a chemiluminescence analyzer. MFNS treatment achieved significant reductions versus placebo for total nasal symptoms (p < 0.001). There were significant decreases of the usual daily activity domain (p < 0.005), outdoor activities (p < 0.01), social function (p < 0.05), and the overall QOL score (p < 0.05) of JRQLQ with MFNS therapy versus placebo. A significant reduction of the sleepiness scale was also observed in the MFNS group with high sleep disturbance (p < 0.01). A significant decrease of nasal NO was found in the MFNS group (p < 0.01), especially among patients with severe nasal symptoms (p < 0.005). This prospective study indicated that MFNS therapy significantly improves nasal symptoms, QOL, sleep quality, and upper airway condition in Japanese subjects with PAR.

    To investigate the effect of alae nasi (AN) activation on nasal resistance, we monitored AN electromyographic (EMG) activity in 17 healthy subjects using surface electrodes placed on either side of the external nares and measured inspiratory nasal resistance utilizing the method of posterior rhinometry. With CO2 inhalation (6 subj), AN EMG activity increased as nasal resistance fell 23 +/- 5% (P less than 0.01). In the same subjects, voluntary flaring of the external nares also increased AN EMG and decreased nasal resistance by 29 +/- 5% (P less than 0.01). Nasal resistance was altered by nasal flaring and CO2 inhalation even after administration of a topical nasal vasoconstrictive spray (8 subj). In six subjects, voluntary nasal flaring or inhibition with the mouth closed produced a 21 +/- 12% change (P less than 0.01) in total airway resistance as measured by body plethysmography. We conclude that activation of the alae nasi will decrease nasal and total airway resistance during voluntary nasal flaring and during CO2 inhalation and thus should be considered in any studies of upper airway resistance.

  20. Differential Diagnosis of Chronic Rhinosinusitis with Nasal Polyps.

    2016-01-01

    Nasal polyps are semi-translucent mucosal outgrowths of the paranasal sinuses which typically arise in the setting of chronic rhinosinusitis (CRS). Nasal polyps are also associated with asthma, aspirin sensitivity, cystic fibrosis and allergic fungal rhinosinusitis (AFS). The majority of nasal polyps are bilateral and characterized by tissue edema and eosinophil infiltration. Patients with nasal polyps often present with complaints including nasal obstruction, congestion, rhinorrhea or altered sense of smell. The differential diagnosis ranges from benign masses such as schneiderian papilloma, antrochoanal polyp, angiofibroma and encephalocele to malignant neoplasms such as squamous cell carcinoma (SCC), esthesioneuroblastoma, nasal lymphoma and rhabdomyosarcoma. These lesions may have a similar appearance as nasal polyps and particular attention to an alternative diagnosis for nasal polyps should be entertained if the mass is unilateral or congenital in nature. Workup for patients with a unilateral mass should include radiographic imaging, possible biopsy and careful follow-up when appropriate. Here, we review the disease etiology of nasal polyps and describe the approach to the patient with nasal polyps with emphasis on differential diagnosis and workup. PMID:27466841

    Led by the federal government, the payers of health care are enacting policies designed to base provider reimbursement on the quality of care they render. This study evaluated and compared patient experiences and satisfaction with nasal decolonization with either nasal povidone-iodine (PI) or nasal mupirocin ointment (MO). A total of 1903 patients were randomized to undergo preoperative nasal decolonization with either nasal MO or PI solution. All randomized patients were also given 2% chlorhexidine gluconate topical wipes. Patients were interviewed prior to discharge to assess adverse events and patient experience with their assigned preoperative antiseptic protocol. Of the 1903 randomized patients, 1679 (88.1%) were interviewed prior to discharge. Of patients receiving PI, 3.4% reported an unpleasant or very unpleasant experience, compared with 38.8% of those using nasal MO (P<.0001). Sixty-seven percent of patients using nasal MO believed it to be somewhat or very helpful in reducing surgical site infections, compared with 71% of patients receiving PI (P>.05). Being recruited as an active participant in surgical site infection prevention was a positive experience for 87.2% of MO patients and 86.3% of PI patients (P=.652). Those assigned to receive PI solution preoperatively reported significantly fewer adverse events than the nasal MO group (P<.01). Preoperative nasal decolonization with either nasal PI or MO was considered somewhat or very helpful by more than two-thirds of patients. PMID:24972440

    Nasal airflow patterns were studied by using xenon 133 gas to image the course taken by air as it flowed through a plastic model of the human nasal cavity. The model was produced from the head of a human cadaver, and was anatomically correct. A needle catheter was used to infuse the radioactive xenon into a continuous flow of room air maintained through the model by a variable vacuum source connected to the nasopharynx. The radioactive gas was infused at one of five release sites in the nostril, and the distribution of the radioactivity was imaged in the sagittal plane with a scintillation camera. The data were organized to show the activity in six contiguous regions of the midnose. For each catheter, release site activity patterns were determined for three flow rates. The results of this experiment showed that both catheter position and flow rate had significant and reproducible effects on the distribution of radioactivity within the model.

    The present study was aimed to investigate the effects of DNS on the structure of nasal cavity. The paranasal sinus coronal view CT of 108 patients with DNS and 129 hospitalized patients without DNS was retrospectively analyzed. The transverse diameter of nasal cavity (a), transverse diameter of nasal cavity and paranasal sinus (b), angle between maxillary and palatal bone, interalveolar distance, and maxillary rotation distance were measured. The ratio of a/b in experimental group was 0.367 ± 0.006 which was significantly (P = 0.0023) less than that in control group (0.391 ± 0.005). For the angle between maxillary and palatal bone, there was no significant difference found between DNS and control group for both right and left sides. The interalveolar distance was 40.75 mm in experimental group, and 38.8 mm in control (P = 0.0002). For the maxillary rotation distance, findings were considered as significant (P < 0.0001) in experimental group (11.25 mm) compared with control (10.1 mm). The present study demonstrates that long-term DNS affects the development of nasal cavity and paranasal sinus, as well as increases the interalveolar distance and maxillary rotation distance. These influences may be caused by the alteration of airflow inside the nasal cavities.

Nasal airflow (measured by anterior rhinomanometry) and subjectively perceived airflow (measured by visual analog scales) were also evaluated. A reduction of NMBF (mL/100 g tissue/min) was observed following local application of 60 micrograms oxymetazoline that was not observed after the vehicle was applied. For example, NMBF at baseline was measured at 78.8 +/- 10.3 mL/100 g tissue/min (mean +/- SEM). During the five minutes following vehicle application, mean values remained at 81.8 +/- 8.8 mL/100 g tissue/min. Five minutes after topical oxymetazoline treatment, NMBF was reduced 49% to 38.3 +/- 10.2 mL/100 g tissue/min. Nasal airflow (mL/sec), which was measured before and after LDV probe placement, was not significantly increased in either the ipsilateral (281.4 +/- 33.1 to 314.3 +/- 31.6) or contralateral nostril (335.7 +/- 26.9 to 262.1 +/- 36.4), probably due to the limited surface application of drug. Subjective assessments of congestion by both the investigator and the subject showed significant improvements in the ipsilateral nostril. We conclude that, under the conditions of our study, localized application of 60 micrograms oxymetazoline significantly reduces superficial nasal blood flow and provides subjectively perceived improvements in nasal stuffiness.

  6. Medicare's fee schedule for hospital outpatient care.

    2002-01-01

    Medicare's hospital outpatient prospective payment system (OPPS) went live on August 1, 2000, after a decade of developmental work. The new system introduced a fee schedule that replaced the cost-related methods that Medicare previously used to reimburse various hospital outpatient services. Hospitals are now paid predetermined rates or fees based on the Ambulatory Patient Classification (APC) groups assigned to the services that Medicare patients receive during outpatient encounters. The new system aims to simplify Medicare's intricate cost-based reimbursement policies, improve hospital efficiency, ensure that payments are sufficient to compensate hospitals for reasonable Medicare costs, and reduce Medicare coinsurance amounts for beneficiaries. Implementation of OPPS-related administrative and operational changes has been a major challenge for hospitals. PMID:12079149

    Cost containment is important in this time of inner-city economic and health-care crisis. Of 28,150 patients treated for gunshot wounds (GSWs) from 1977 through 1991, 16,892 (60%) were treated as outpatients after emergency department evaluation and treatment. The complication rate was 1.8% (mostly infections), and nine patients were later found to have vascular injuries requiring surgical treatment. These were identified later at outpatient follow-up and treated with no long-term morbidity or mortality. A conservative estimate of the cost savings from this study was more than $37 million. With a more liberal use of angiography to eliminate rare missed vascular injuries, many GSW victims can be safely treated as outpatients, eliminating the need for expensive in-hospital observation.

    Six male prisoners who misused xylometazoline nasal drops by inhalation were interviewed by a prison physician in 2006. The prisoners received xylometazoline drops during regular visits in the prison ambulatory service. In order to get the medication, the subjects reported false symptoms of rhinosinusitis and allergic reactions. Psychoactive effects of inhaled xylometazoline were described as "stimulation," "excitation," and "feeling of strength." Although preliminary, our findings suggest that topical adrenergic decongestants can produce rewarding effects when administered by inhalation. PMID:19085441

    Using the nasal route to deliver pharmaceutical aerosols to the lungs has a number of advantages including co-administration during non-invasive ventilation. The objective of this study was to evaluate the growth and deposition characteristics of nasally administered aerosol throughout the conducting airways based on delivery with streamlined interfaces implementing two forms of controlled condensational growth technology. Characteristic conducting airways were considered including a nose-mouth-throat (NMT) geometry, complete upper tracheobronchial (TB) model through the third bifurcation (B3), and stochastic individual path (SIP) model to the terminal bronchioles (B15). Previously developed streamlined nasal cannula interfaces were used for the delivery of submicrometer particles using either enhanced condensational growth (ECG) or excipient enhanced growth (EEG) techniques. Computational fluid dynamics (CFD) simulations predicted aerosol transport, growth and deposition for a control (4.7 μm) and three submicrometer condensational aerosols with budesonide as a model insoluble drug. Depositional losses with condensational aerosols in the cannula and NMT were less than 5% of the initial dose, which represents an order-of-magnitude reduction compared to the control. The condensational growth techniques increased the TB dose by a factor of 1.1–2.6x, delivered at least 70% of the dose to the alveolar region, and produced final aerosol sizes ≥2.5 μm. Compared to multiple commercial orally inhaled products, the nose-to-lung delivery approach increased dose to the biologically important lower TB region by factors as large as 35x. In conclusion, nose-to-lung delivery with streamlined nasal cannulas and condensational aerosols was highly efficient and targeted deposition to the lower TB and alveolar regions. PMID:24932058

    This study aimed to investigate the prevalence of human papilloma virus (HPV), herpes simplex virus-1/-2 (HSV-1/-2), varicella-zoster virus (VZV), Epstein-Barr virus (EBV), cytomegalovirus (CMV), and human herpes virus-6/-7 (HHV-6/-7) in 23 human nasal polyps by applying PCR. Two types of control tissues were used: adjacent inferior/middle turbinates from the patients and inferior/middle turbinates from 13 patients undergoing nasal corrective surgery. EBV was the virus most frequently detected (35%), followed by HPV (13%), HSV-1 (9%), and CMV (4%). The CMV-positive polyp was simultaneously positive for HSV-1. HPV was also detected in the adjacent turbinates (4%) and the adjacent middle turbinate (4%) of one of the HPV-positive patients. EBV, HSV, and CMV were not detected in the adjacent turbinates of the EBV-, HSV- or CMV-positive patients. All mucosae were negative for the VZV, HHV-6, and HHV-7. This is the first study to deal with the involvement of a comparable group of viruses in human nasal polyposis. The findings support the theory that the presence of viral EBV markedly influences the pathogenesis of these benign nasal tumors. The low incidence of HPV detected confirms the hypothesis that HPV is correlated with infectious mucosal lesions to a lesser extent than it is with proliferative lesions, such as inverted papilloma. The low incidence of HSV-1 and CMV confirms that these two herpes viruses may play a minor role in the development of nasal polyposis. Double infection with HSV-1 and CMV may also play a minor, though causative, role in nasal polyp development. VZV and HHV-6/-7 do not appear to be involved in the pathogenesis of these mucosal lesions.

    The AA. describe an intravenous out-patient anaesthesia, utilized in oral surgery; it is called "conscious ketamina-neuroleptanalgesia". This original technique produces a heavy sedation of the patients without losing their consciousness and their capacity to collaborate; infact the verbal contact with the patient is maintained through the period of sedation. In this technique the use of local anesthetics is not suitable because analgesia is enough.

    Background The septal cartilage is the most useful donor site for autologous cartilage graft material in rhinoplasty. For successful nasal surgery, it is necessary to understand the developmental process of the nasal septum and to predict the amount of harvestable septal cartilage before surgery. Methods One hundred twenty-three Korean patients who underwent three-dimensional (3D) facial bone computed tomography (CT) were selected for evaluation of the midsagittal view of the nasal septum. Multiple parameters such as the area of each component of the nasal septum and the amount of harvestable septal cartilage were measured using Digimizer software. Results The area of the total nasal septum showed rapid growth until the teenage years, but thereafter no significant change throughout the lifetime. However, the development of the septal cartilage showed a gradual decline due to ossification changes with aging after puberty in spite of a lack of change in the total septal area. The area of harvestable septal cartilage in young adults was 549.84±151.26 mm2 and decreased thereafter with age. Conclusions A 3D facial bone CT scan can provide valuable information on the septal cartilage graft before rhinoplasty. Considering the developmental process of the septal cartilage identified in this study, septal surgery should not be performed until puberty due to the risk of nasal growth impairment. Furthermore, in elderly patients who show a decreased cartilage area due to ossification changes, septal cartilage harvesting should be performed carefully due to the risk of saddle nose deformity.

    Background Obstetric fistula is a childbirth injury prevalent in sub-Saharan Africa that causes uncontrollable leaking of urine and/or feces. Research has documented the social and psychological sequelae of obstetric fistula, including mental health dysfunction and social isolation. Purpose This cross-sectional study sought to quantify the psychological symptoms and social support in obstetric fistula patients, compared with a patient population of women without obstetric fistula. Methods Participants were gynecology patients (N = 144) at the Kilimanjaro Christian Medical Center in Moshi, Tanzania, recruited from the Fistula Ward (n = 54) as well as gynecology outpatient clinics (n = 90). Measures included previously validated psychometric questionnaires, administered orally by Tanzanian nurses. Outcome variables were compared between obstetric fistula patients and gynecology outpatients, controlling for background demographic variables and multiple comparisons. Results Compared to gynecology outpatients, obstetric fistula patients reported significantly higher symptoms of depression, posttraumatic stress disorder, somatic complaints, and maladaptive coping. They also reported significantly lower social support. Conclusions Obstetric fistula patients present for repair surgery with more severe psychological distress than gynecology outpatients. In order to address these mental health concerns, clinicians should engage obstetric fistula patients with targeted mental health interventions. PMID:25670025

    1994-03-01

    Naphazoline, a sympathomimetic and an imidazoline derivative, is used as 0.05-0.1% solution for local decongestion of the nasal and ocular mucosa. In excessive dosage, or if ingested by accident, may cause depression of the central nervous system (disturbances of consciousness progressing to coma), hypothermia, bradycardia and sweating. These naphazoline effects are particularly strongly pronounced in children. Anglo-Saxon pharmacotherapy excludes the application of naphazoline nasal drops in children younger than six years, whereas the Croatian pharmacotherapeutic literature (and practice) allows its use even in infancy. At the Kantrida Paediatric Clinic, Clinical Hospital Centre in Rijeka, 11 children with signs of intoxication with naphazoline nasal drops were hospitalized from 1990 to 1992. The symptoms pertaining to the central nervous system i.e. disturbances of consciousness in the form of somnolence were clearly marked in all children. Some children developed skin pallor, bradycardia, bradypnoea and hypothermia. Resolution occurred within 24 hours and the findings returned to normal values. Clinical picture followed by rapid resolution and normal findings, with a personal history of drug taking, is a safe indication for diagnosis. There are several reasons to account for intoxication (drops difficult to use with children, containers inadequate for proper dosage), but the major factor is the age of the patient--all hospitalized children were younger than six years. It is pointed out that administration of naphazoline drops at an early age is not advisable.

    Nose has an important role in the aesthetics of face. It is easy to understand the reason of the major interest that has revolved around the correction of its imperfections for several centuries, or even from the ancient times. In the last decade, all the surgical or medical minimal-invasive techniques evolved exponentially. The techniques of rejuvenation and corrections of nasal imperfections did not escape this development that is much widespread in the medicine of the third millennium. In many cases, the techniques of surgical correction involve invasive procedure that necessitates, for the majority of cases, hospitalisation. The author, using a different approach, has developed mini-invasive techniques using botulinum toxin A (BTxA) and absorbable fillers for the correction of nasal imperfections. BTxA allows to reduce the imperfections due to hypertension of muscles, while the absorbable fillers allow to correct all the imperfections of the nasal profile from the root to the tip in total safety. The correction is based on the precise rules that allow avoiding the majority of side effects. Results are long lasting and well appreciated by patients. PMID:23060706

It can have a significant impact on quality of life and interferes with both attendance and performance at school and at work.1 Intranasal corticosteroids are widely recognised as the most effective symptomatic treatment available, but oral or intranasal new generation antihistamines are usually offered as first-line treatment for intermittent symptoms.1,2 Patients with moderate to severe allergic rhinitis may require a combination of drugs, and many patients only achieve limited control of their symptoms.3 Dymista is described as a novel intranasal formulation combining the antihistamine azelastine hydrochloride with the corticosteroid fluticasone propionate.3 It is licensed for the relief of symptoms of moderate to severe seasonal and perennial allergic rhinitis in adults and adolescents if monotherapy with either intranasal antihistamine or glucocorticoid is not considered sufficient.4 The manufacturer claims that compared with fluticasone or azelastine alone, Dymista is twice as effective (when placebo effect is excluded) in providing relief from both nasal and ocular symptoms, and leads to greater overall relief from nasal symptoms. It also claims that Dymista controls nasal symptoms up to 6 days faster than fluticasone.5 Here we consider the evidence for Dymista and whether it represents a significant advantage in the management of patients with allergic rhinitis.

    This research focuses on creating a standardized nasal cavity model of adult Malaysian females. The methodology implemented in this research is a new approach compared to other methods used by previous researchers. This study involves 26 females who represent the test subjects for this preliminary study. Computational fluid dynamic (CFD) analysis was carried out to better understand the characteristics of the standardized model and to compare it to the available standardized Caucasian model. This comparison includes cross-sectional areas for both half-models as well as velocity contours along the nasal cavities. The Malaysian female standardized model is larger in cross-sectional area compared to the standardized Caucasian model thus leading to lower average velocity magnitudes. The standardized model was further evaluated with four more Malaysian female test subjects based on its cross-sectional areas and average velocity magnitudes along the nasal cavities. This evaluation shows that the generated model represents an averaged and standardized model of adult Malaysian females. PMID:23840279

    To maximize outcomes from endoscopic skull base surgery, careful early postoperative management is critically important. Standardized postoperative regimens are lacking. The type of reconstruction and presence and type of cerebrospinal fluid leak dictate management. If a leak is encountered intraoperatively, patients should avoid maneuvers that increase intracranial pressures for at least 1 month. Early postoperative care focuses on minimizing and managing nasal crusting. This article reviews the evidence in the literature on postoperative management, complications, and quality of life after surgery, and outlines our experience in the management of patients after endoscopic skull base surgery.

    Juvenile nasopharyngeal angiofibroma is a source of controversy with respect to therapy because of the many therapeutic modalities that exist, such as classic surgical techniques and newer techniques like nasal endoscopic surgery, which have emerged with the advent of new and better diagnostic techniques. Endoscopic surgery is less aggressive and produces less morbidity, but its use often depends on the size and extension of the tumor. A clinical case is presented with the subsequent diagnostic steps and surgical treatment. Rigid endoscopy was used for double cynoacrylate embolization, by angiography before operation and intratumoral injection during surgery.

    2003-07-01

    Nasal cysts are rare complications of rhinoplasty, and numerous theories exist regarding their cause. The term "paraffinoma" has been used to describe cyst formation observed after topical antibiotic ointment application with nasal packing in the immediate postoperative period. Such complications are rare but may occur because of the inherent properties of the agent used or a lack of meticulous technique (in the placement of incisions and nasal packing). Three cases of postrhinoplasty cysts with a variety of presentations, including incidental intraoperative findings, bilateral medial canthal masses, and a draining dorsal cyst, are described. Although such cysts are uncommon, techniques to prevent these unwanted sequelae should routinely be used, with the judicious application of non-petroleum-based topical antibiotic preparations.

    2014-01-01

    Our goal was to revise the literature about external nasal dilators (ENDs) as to their definition, history, and current uses. We reviewed journals in the PubMed and MEDLINE databases. The current uses hereby presented and discussed are physical exercise, nasal congestion and sleep, snoring, pregnancy, cancer, and healthy individuals. Numerous studies have shown that ENDs increase the cross-sectional area of the nasal valve, reducing nasal resistance and transnasal inspiratory pressure and stabilizing the lateral nasal vestibule, avoiding its collapse during final inspiration. These effects also facilitate breathing and are beneficial to patients with nasal obstruction. Furthermore, END use is simple, noninvasive, painless, affordable, and bears minimum risk to the user. Most studies have limited sample size and are mainly focused on physical exercise. In conclusion, ENDs seem useful, so further studies involving potential effects on the performance of physical tests and improvements in sleep quality are necessary, especially in children and teenagers.

    2016-01-01

    Background and Aims: Face mask ventilation of the edentulous patient is often difficult as ineffective seating of the standard mask to the face prevents attainment of an adequate air seal. The efficacy of nasal ventilation in edentulous patients has been cited in case reports but has never been investigated. Material and Methods: Consecutive edentulous adult patients scheduled for surgery under general anesthesia with endotracheal intubation, during a 17-month period, were prospectively evaluated. After induction of anesthesia and administration of neuromuscular blocker, lungs were ventilated with a standard anatomical face mask of appropriate size, using a volume controlled anesthesia ventilator with tidal volume set at 10 ml/kg. In case of inadequate ventilation, the mask position was adjusted to achieve best-fit. Inspired and expired tidal volumes were measured. Thereafter, the face mask was replaced by a nasal mask and after achieving best-fit, the inspired and expired tidal volumes were recorded. The difference in expired tidal volumes and airway pressures at best-fit with the use of the two masks and number of patients with inadequate ventilation with use of the masks were statistically analyzed. Results: A total of 79 edentulous patients were recruited for the study. The difference in expiratory tidal volumes with the use of the two masks at best-fit was statistically significant (P = 0.0017). Despite the best-fit mask placement, adequacy of ventilation could not be achieved in 24.1% patients during face mask ventilation, and 12.7% patients during nasal mask ventilation and the difference was statistically significant. Conclusion: Nasal mask ventilation is more efficient than standard face mask ventilation in edentulous patients. PMID:27625477

    Laser-assisted in situ keratomileusis (LASIK) eye surgery is increasingly common, with approximately 600,000 procedures performed each year in the United States. LASIK eye surgery is typically performed in an outpatient setting and involves the use of a machine-guided laser to reshape the lens of the eye to correct vision irregularities. Clinic A is an ambulatory surgery center that performs this procedure on 1 day each month. On February 5, 2015, the Toledo-Lucas County Health Department (TLCHD) in Ohio was notified of eye infections in two of the six patients who had undergone LASIK procedures at clinic A on January 9, 2015. The two patients experienced eye pain after the procedures and received diagnoses of infection with Mycobacterium chelonae, an environmental organism found in soil and water. PMID:26492452

    1989-01-01

    The extent of unnecessary surgery has been the object of considerable speculation and occasional wild accusation in recent years. Most evidence of the existence of unnecessary surgery, such as information from studies of geographic variations and the results of second surgical opinion programs, is circumstantial. However, results from the few studies that have measured unnecessary surgery directly indicate that for some highly controversial operations the fraction that are unwarranted could be as high as 30 percent. Most unnecessary surgery results from physician uncertainty about the effectiveness of an operation. Elimination of this uncertainty requires more efficient production and dissemination of scientific information about clinical effectiveness. In the absence of adequate data from scientific studies, the use of a consensus of expert opinion, disseminated by means of comprehensive practice guidelines, offers the best opportunity to identify and eliminate unnecessary surgery.

    The spectral analysis of the nasal sound is an indicator of the nasal airflow pattern. We investigated a new technique for nasal sound analysis via Internet. This study includes 27 patients and 22 healthy people. Patients were treated by septoplasty operation for septal deviation. Postoperation 10(th) day, this technique was applied to follow nasal airflow course. The patients recorded the nasal sound by microphone into the computer as a .wav file and sent us via internet, all those records were evaluated by us. The results were sent back to themselves. The 11 patients who had nasal obstruction symptoms (group A) were called to the hospital to check. In the nasal sound analyses e-mails of those patients, the sound intensity was at high frequencies (2-4 kHz, 4-6 kHz) above 30 dB, but low (500-1000 Hz) and medium frequencies (1-2 kHz), are below then 10 dB. In the patients without nasal obstruction symptom (group B), the sound intensity was at high frequencies below 10 dB, but low and medium frequencies are above 20 dB. There was a statistically significant difference in sound intensity between group A and group B. In the endoscopical examination of those obstructions, which decreases the nasal airway, crusting formation in the nasal cavity was found. Web-based nasal sound analysis is an important method to follow the postoperative course and the nasal airflow evaluation. The new method will save time and money, avoiding a return visit to the hospital unnecessarily.

    Warren, D W; Hairfield, W M; Dalston, E T

    1991-04-01

    The purpose of this study was to assess the oral response to severe nasal airway impairment in patients with cleft palate. Inductive plethysmography was used to measure the percent of nasal breathing, and the pressure-flow technique was used to estimate nasal area in 15 persons with severe nasal airway impairment. Mean nasal area was 0.17 cm2, and the average percent of nasal breathing was 20%. Analysis revealed a strong correlation (0.87) between nasal size and percent of nasal breathing in this selected group. Modeling studies based on the mean values from the subjects' data indicated that the model "mouth" would have to open 0.5 cm2 to shunt 80% of the airflow orally, an amount equivalent to the mean value of the subjects' respiratory mode. More important, the extrapolated data revealed that upper-airway resistance decreased in the model from 8.7 cm H2O/L/sec to a level of 3.2 cm H2O/L/sec, which is an average value for healthy adults. These data support the concept that the mouth acts as a variable resistor to maintain an optimal respiratory tract resistance when the nasal airway is impaired. PMID:2008894

    Recent evidence strongly suggests that the microbiota of the nasal cavity plays a crucial role in determining the reaction patterns of the mucosal and systemic immune system. However, little is known about the normal microbiota of the nasal cavity. The purpose of this study was to determine the microbiota in different parts of the nasal cavity and to develop and evaluate methods for this purpose. Samples were collected from 10 healthy adults by nasal washes and by swabbing of the mucosa through a sterile introduction device. Both methods gave results that were quantitatively and qualitatively reproducible, and revealed significant differences in the density of the nasal microbiota between individuals. The study revealed absence of gram-negative bacteria that are regular members of the commensal microbiota of the pharynx. Likewise, viridans type streptococci were sparsely represented. The nasal microbiota was dominated by species of the genera Corynebacterium, Aureobacterium, Rhodococcus, and Staphylococcus, including S. epidermis, S. capitis, S. hominis, S. haemolyticus, S. lugdunensis and S. warneri. These studies show that the microbiota of the nasal cavity of adults is strikingly different from that of the pharynx, and that the nasal cavity is a primary habitat for several species of diphtheroids recognized as opportunistic pathogens. Under special circumstances, single species, including IgA1 protease-producing bacteria, may become predominant in a restricted area of the nasal mucosa. PMID:11200821

    From September 1995 to July 1996 50 patients were treated for carpal tunnel syndrome as outpatients by endoscopic release in the rooms of an orthopaedic surgeon (two-portal-technique). The average age was 51.3 years (27–61 years). The average length of symptoms was 43 months, the postoperative time off work averaged 27 days. Six months postoperatively wasting of the thenar persisted in 2 out of 16 patients, a positive Tinel's sign in 1 out of 46 patients and delayed median nerve conduction in 2 out of 48 presenting these symptoms preoperatively. At 6 months the average handgrip strength had recovered to 109% of the preoperative value. One out of 49 patients still presented paresthesia and 1 out of 50 nocturnal dysesthesia. There were minor complications in 7 patients (14%), only one patient requires further treatment. We conclude that endoscopic carpal tunnel release done on outpatients in a private surgery can be reliable, safe and cost efficient. PMID:18493471

    The objective of the present study was to evaluate therapeutic effects of sinusoidal modulated currents (SMC) applied for the treatment of patients at different stages of biliary sludge (BS) under conditions of an outpatient clinic. Biliary sludge is currently considered to be a precursor of cholelithiasis known to be a leading pathology of the digestive system responsible for the high surgery rate. It was shown that the introduction of the technique based on sinusoidal modulated currents into the clinical practice of an outpatient clinic increases the efficacy of management of the patients presenting with stage 1 and 2 biliary sludge and showing neither well-apparent clinical symptoms nor signs of metabolic disorders that imply the necessity of more thorough examination and combined application of sinusoidal modulated currents and mediacmental therapy.

    Purpose The aim of the study was to analyze the effects of uneventful phacoemulsification surgery on choroidal thickness (CT) using spectral domain optical coherence tomography (SD-OCT). Methods In this prospective study, 38 eyes of 38 patients having phacoemulsification surgery were included. All patients underwent detailed ophthalmologic examination, including preoperative axial length (AXL) measurement with optical biometry and intraocular pressure (IOP) measurement preoperatively and 1 month postoperatively. The CT was measured perpendicularly at the fovea and 1.5 mm temporal, 3.0 mm temporal, 1.5 mm nasal, and 3.0 mm nasal using SD-OCT preoperatively and 1 month postoperatively. Changes in the CT after surgery and correlation of this change with age, AXL, preoperative IOP, and IOP change were evaluated. Results There was a statistically significant increase in the CT at all regions evaluated. This increment was more prominent in the nasal and subfoveal regions. The IOP decreased significantly 1 month after surgery (16.14±4.94 mmHg vs 13.91±4.86 mmHg; P<0.001). The change in IOP was correlated with the CT changes at all regions, whereas age, AXL, and preoperative IOP had no significant correlations with the changes in CT. Conclusion Phacoemulsification surgery may cause significant increase in CT, which is correlated with surgery-induced IOP change in the short term. Long-term follow-up of eyes having phacoemulsification surgery may provide further insight into the effects of cataract surgery on the choroid. PMID:27307699

    Unanticipated, reactive motion of the patient during skull based tumor resective surgery is the source of the consequence that the nasal endoscopic tracking system is compelled to be recalibrated. To accommodate the calibration process with patient's movement, this paper developed a Kinect based Real-time positional calibration method for nasal endoscopic surgical navigation system. In this method, a Kinect scanner was employed as the acquisition part of the point cloud volumetric reconstruction of the patient's head during surgery. Then, a convex hull based registration algorithm aligned the real-time image of the patient head with a model built upon the CT scans performed in the preoperative preparation to dynamically calibrate the tracking system if a movement was detected. Experimental results confirmed the robustness of the proposed method, presenting a total tracking error within 1 mm under the circumstance of relatively violent motions. These results point out the tracking accuracy can be retained stably and the potential to expedite the calibration of the tracking system against strong interfering conditions, demonstrating high suitability for a wide range of surgical applications.

    Introduction Topical airway anesthesia is known to improve tolerance and patient satisfaction during flexible bronchoscopy (FB). Lidocaine is commonly used, delivered as an atomized spray. The current study assesses safety and patient satisfaction for nasal anesthesia of a new atomization device during outpatient bronchoscopy in lung transplant recipients. Methods Using a prospective, non-blinded, cross-over design, patients enrolled between 01-10-2014 and 24-11-2014 received 2% lidocaine using the standard reusable nasal atomizer (CRNA). Those enrolled between 25-11-2014 and 30-01-2015, received a disposable intranasal mucosal atomization device (DIMAD). After each procedure, the treating physician, their assistant and the patient independently rated side-effects and satisfaction, basing their responses on visual analogue scales (VAS). At their next scheduled bronchoscopy during the study period, patients then received the alternative atomizer. Written consent was obtained prior to the first bronchoscopy, and the study approved by the institutional ethics committee. Results Of the 252 patients enrolled between 01-10-2014 and 30-01-2015, 80 (32%) received both atomizers. Physicians reported better efficacy (p = 0.001) and fewer side effects (p< = 0.001) for DIMAD in patients exposed to both procedures. Among patients with one visit, physicians and their assistants reported improved efficacy (p = 0.018, p = 0.002) and fewer side effects (p< = 0.001, p = 0.029) for the disposable atomizer, whereas patients reported no difference in efficacy or side effects (p = 0.72 and p = 0.20). No severe adverse events were noted. The cost of the reusable device was 4.08€ per procedure, compared to 3.70€ for the disposable device. Discussion Topical nasal anesthesia via a disposable intranasal mucosal atomization device (DIMAD) offers comparable safety and patient comfort, compared to conventional reusable nasal atomizers (CRNA) in lung transplant recipients.

    Introduction Measuring the patient satisfaction is a very important issue that will help very much in improving the service provided to patients and improve the level of satisfaction. Aim To evaluate patient satisfaction with the cataract surgery service and identify any areas for improvement, determination of patient satisfaction with referral, out-patient consultation, pre-assessment clinic, surgery and post-operative care, also to report patients' comments relating to improvement in service provision. Methodology A retrospective study was undertaken for 150 patients underwent cataract surgery at Barrow General Hospital, UK, the survey sample was by postal questionnaires. We collected our data from the theatre lists for a period of 4 month. Results This study included 150 patients; the response rate was (72%) 108 patients, Most patients were referred from their general practitioner 86.1%, 93 (86.1%) patients were happy with the time interval from seeing their GP to eye clinic. In the eye out patient department many factors significantly affected the level of patient satisfaction, in general the more information provided for the patient the more the satisfaction. Conclusion Patient satisfaction is on important health outcome old understanding both the domains of satisfaction as well as their relative importance to patients is necessary to improve the overall quality of patient care. Meeting the doctor, presenting all relevant information and giving printed information are very important factors in improving the patient's satisfaction with cataract surgery. PMID:18950523

  13. Vitamin D decreases the secretion of eotaxin and RANTES in nasal polyp fibroblasts derived from Taiwanese patients with chronic rhinosinusitis with nasal polyps.

    Eosinophils are important inflammatory cells involved in the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP). Vitamin D and its derivatives, in addition to their classic role as regulators of electrolytes homeostasis, have modulatory effects in immunological and inflammatory responses. Such properties suggest that vitamin D might also play a role in inflammatory airway diseases such as CRSwNP. In this study, we investigated the effect of vitamin D derivatives (calcitriol and tacalcitol) on the secretion of eotaxin and Regulated on Activation, Normal T Cell Expressed and Secreted (RANTES), the two major eosinophil chemoattractants, in fibroblasts derived from the polyps of Taiwanese CRSwNP patients. Patients diagnosed with eosinophilic CRSwNP but without malignancies or asthma and undergoing elective endoscopic sinus surgery were recruited. Three primary fibroblast cultures were established using the polyp specimens obtained from these patients. The third to eighth passages of the fibroblasts were used for in vitro studies. Nasal polyp-derived fibroblasts were stimulated with IL-1β (10 ng/mL) for 24 hours, followed by replacement with media alone or with calcitriol or tacalcitol (10 μM) and incubation for another 24 hours. After the treatments, the levels of secreted eotaxin and RANTES were evaluated by ELISA assays. The results showed that IL-1β could substantially stimulate the secretion of eotaxin (p < 0.01) and RANTES (p < 0.01) in nasal polyp-derived fibroblasts. More importantly, this stimulatory effect was significantly suppressed by adding calcitriol (p ≤ 0.002 for eotaxin and p ≤ 0.008 for RANTES) or tacalcitol (p ≤ 0.009 for eotaxin and p ≤ 0.02 for RANTES). Therefore, the inhibitory effect of vitamin D derivatives on eotaxin and RANTES secretion might shed light not only on the disease mechanism, but also on the potential use of vitamin D in pharmacotherapy of Taiwanese patients with CRSwNP.

    Noninvasive objective evaluation of nasal airflow is one of the important clinical aspects. The developed polyvinylidene fluoride (PVDF) sensor enables measurement of airflow through each side of the nose using its piezoelectric property. This study was designed to evaluate the diagnostic capability of the PVDF sensor in assessing the deviated nasal septum (DNS). PVDF nasal sensor uses its piezoelectric property to measure the peak-to-peak amplitude (Vp-p) of nasal airflow in both of the nostrils: right nostril (RN) and left nostril (LN), separately and simultaneously. We have compared the results of PVDF nasal sensor, visual analog scale (VAS), and clinician scale for 34 DNS patients and 28 healthy controls. Additionally, the results were further analyzed by receiver operating characteristic curve and correlation between PVDF nasal sensor and VAS in detecting DNS. We found a significant difference in the peak-to-peak amplitude values of the test group and the control group. The correlation between the PVDF nasal sensor measurements and VAS (RN and LN combined) for test group was statistically significant (-0.807; p < 0.001). Sensitivity and specificity of the PVDF nasal sensor measurements in the detection of DNS (RN and LN combined) was 85.3 and 74.4%, respectively, with optimum cutoff value ≤0.34 Vp-p. The developed PVDF nasal sensor is noninvasive and requires less patient efforts. The sensitivity and specificity of the PVDF nasal sensor are reliable. According to our findings, we propose that the said PVDF nasal sensor can be used as a new diagnostic tool to evaluate the DNS in routine clinical practice.

    Necrotizing sialometaplasia is a disease process which affects minor salivary glands. It may clinically and microscopically resemble squamous cell or mucoepidermoid carcinoma but is histologically benign. Thirteen patients with this process occurring on the hard palate have been reported in the past two years. We describe two cases in the nasal cavity and propose that compromise of the blood supply contributed to the occurrence of these lesions. This apparently benign lesion may represent nonspecific reaction of salivary and mucous glands to ischemic injury and must be distinguished from carcinoma.

    Pleomorphic adenoma is the most common benign tumor of glandular tissue occurring in the head and neck region. There have been several reports of metastasis of this benign-appearing tumor from the salivary glands to distant sites, suggesting hematogenous spread and implantation. Although occurrence of pleomorphic adenoma on the nasal septum has been described, to our knowledge this is the first reported case of recurrent septal pleomorphic adenoma with histologically benign tissue in an enlarged metastatic ipsilateral submandibular lymph node, suggesting lymphatic spread. The literature concerning the subject is reviewed. Wide septal excision and modified neck dissection is the recommended treatment.

    External nasal splinting is performed routinely after nasal bone fracture reductions, osteotomies, and rhinoplasties. Materials commonly used include plaster of Paris (POP), thermoplastic splints, self-adhesive padded aluminium splints, and Orthoplast, among many others. The disadvantages of these materials are described in this paper, and polyvinyl siloxane is recommended as an effective and more readily available alternative material to counter these pitfalls.

  6. Chitosan in nasal delivery systems for therapeutic drugs.

    2014-09-28

    There is an obvious need for efficient and safe nasal absorption enhancers for the development of therapeutically efficacious nasal products for small hydrophilic drugs, peptides, proteins, nucleic acids and polysaccharides, which do not easily cross mucosal membranes, including the nasal. Recent years have seen the development of a range of nasal absorption enhancer systems such as CriticalSorb (based on Solutol HS15) (Critical Pharmaceuticals Ltd), Chisys based on chitosan (Archimedes Pharma Ltd) and Intravail based on alkylsaccharides (Aegis Therapeutics Inc.), that is presently being tested in clinical trials for a range of drugs. So far, none of these absorption enhancers have been used in a marketed nasal product. The present review discusses the evaluation of chitosan and chitosan derivatives as nasal absorption enhancers, for a range of drugs and in a range of formulations such as solutions, gels and nanoparticles and finds that chitosan and its derivatives are able to efficiently improve the nasal bioavailability. The revirtew also questions whether chitosan nanoparticles for systemic drug delivery provide any real improvement over simpler chitosan formulations. Furthermore, the review also evaluates the use of chitosan formulations for the improvement of transport of drugs directly from the nasal cavity to the brain, based on its mucoadhesive characteristics and its ability to open tight junctions in the olfactory and respiratory epithelia. It is found that the use of chitosan nanoparticles greatly increases the transport of drugs from nose to brain over and above the effect of simpler chitosan formulations. PMID:24818769

    Background Staphylococcus aureus nasal colonization burden has been identified as a risk factor for infection. This study evaluates methicillin-resistant S aureus (MRSA) nasal burden, as defined by the cycle threshold (Ct) and risk of subsequent infection. Methods In a retrospective cohort study, United States veterans were classified into 3 MRSA nasal colonization groups: noncarriers, low burden (Ct > 24 cycles), and high burden (Ct ≤ 24 cycles). MRSA infections were identified prospectively, and clinical information was obtained by chart review. Multivariate logistic regression assessed the association of MRSA nasal burden and risk of MRSA infection. Results During 4-years of follow-up, 4.3% of noncarriers, 18.5% of low burden, and 17.2% of high burden developed a MRSA infection. In multivariate analysis, MRSA nasal colonization was a risk factor for MRSA infection (P = .008) with low burden (risk ratio [RR], 3.62; 95% confidence interval [CI]: 1.47–8.93) and high burden (RR, 2.71; 95% CI: 0.95–7.72) associated with subsequent MRSA infection when compared with noncarriers. When compared with low burden, high burden nasal carriers were not at increased risk of infection (RR, 0.75; 95% CI 0.36–1.55). Conclusion MRSA nasal colonization was a risk factor for MRSA infection. High nasal burden of MRSA did not increase the risk of infection. PMID:23261345

    The nasal mucosa, the first tissue of contact for inhaled xenobiotics, possesses substantial enobiotic-metabolizing capacti. Enzymes of the nasal cavity may metabolize xenobiotics to innocuous, more water-soluble compounds that are eliminated from the body, or they may bioactivate them to toxic metabolites. These toxic metabolites may find to cellular macromolecules in the nasal cavity or be transported to other parts of the body where they may react. Nasal carcinogenesis in rodents often results from bioactivation of xenobiotics. The increased incidences of nasal tumors associated with certain occupations suggest that xenobiotic bioactivation may be important in human nasal cancer etiology, as well. The increasing popularity of the nose as a route of drug administration makes information concerning nasal drug metabolism and disposition vital to accomplish therapeutic goals. For these reasons, the study of xenobiotic-met abolizing capacity of the nasal cavity is an important area of health-related research. In the present study, we have confirmed the presence of CYP2A6 mRNA in human respiratory mucosa.

  20. Chitosan in nasal delivery systems for therapeutic drugs.

    PubMed

    Casettari, Luca; Illum, Lisbeth

    2014-09-28

    There is an obvious need for efficient and safe nasal absorption enhancers for the development of therapeutically efficacious nasal products for small hydrophilic drugs, peptides, proteins, nucleic acids and polysaccharides, which do not easily cross mucosal membranes, including the nasal. Recent years have seen the development of a range of nasal absorption enhancer systems such as CriticalSorb (based on Solutol HS15) (Critical Pharmaceuticals Ltd), Chisys based on chitosan (Archimedes Pharma Ltd) and Intravail based on alkylsaccharides (Aegis Therapeutics Inc.), that is presently being tested in clinical trials for a range of drugs. So far, none of these absorption enhancers have been used in a marketed nasal product. The present review discusses the evaluation of chitosan and chitosan derivatives as nasal absorption enhancers, for a range of drugs and in a range of formulations such as solutions, gels and nanoparticles and finds that chitosan and its derivatives are able to efficiently improve the nasal bioavailability. The revirtew also questions whether chitosan nanoparticles for systemic drug delivery provide any real improvement over simpler chitosan formulations. Furthermore, the review also evaluates the use of chitosan formulations for the improvement of transport of drugs directly from the nasal cavity to the brain, based on its mucoadhesive characteristics and its ability to open tight junctions in the olfactory and respiratory epithelia. It is found that the use of chitosan nanoparticles greatly increases the transport of drugs from nose to brain over and above the effect of simpler chitosan formulations.

    Introduction: This study was performed to evaluate the correlation between the objective and subjective sensation of nasal patency, assessed through a validated questionnaire, the Italian version of the NOSE scale, and the rhinomanometric results in a large cohort of patients complaining about nasal obstruction. Materials and Methods: Data was obtained from a total of 233 adult patients, (123 males, 110 females, with a mean age of 43.7 years) with a diagnosis of septal deviation and complaining about nasal obstruction. Anterior active rhinomanometry was used for objective assessment, while the I-NOSE scale and a visual analog scale (VAS) were used for subjective evaluation. Results: Positive correlations between I-NOSE scores and VAS and rhinomanometric results were found. The higher correlation was demonstrated between the HUNR (higher unilateral nasal resistance) parameter of rhinomanometry and the second item of the I-NOSE scale (Nasal blockage or obstruction). No significant correlation was found between the fourth item of the I-NOSE (Trouble sleeping) and the VAS score. The VAS score appeared mildly, but still significantly, correlated with the HUNR parameter of rhinomanometry. Conclusion: The correlation between the subjective sensation of nasal patency and the rhinomanometric data proved to be significant. No correlation between subjective sensation of trouble sleeping and rhinomanometric assessment was found. In counselling with patients complaining of nasal obstruction trouble in sleeping should not be considered as a symptom related to nasal obstruction. PMID:27738607

    Angiolipomas are benign adipose tumors. There are two types: infiltrating and noninfiltrating. An angiolipoma presenting as a nasal mass is rare. To our knowledge, this is only the second documented case of angiolipoma presenting in the nasal dorsum. Total surgical excision by an external rhinoplasty technique with close follow-up is advised. Recurrence is not common.

    This study aimed to investigate the methods, effects, and application value of a combination of CO2 laser-assisted uvulopalatopharyngoplasty (UPPP) and selective nasal cavity expansion for the treatment of multiplanar narrowing-induced obstructive sleep apnea hypopnea syndrome (OSAHS). Ninety-three patients with OSAHS and multiplanar stenosis were treated with CO2 laser-assisted modified UPPP and selective surgical expansion of the nasal cavity, with 12 completing the operation in stages. Six months after the operation, 23 patients (24.7%) were effectively cured, 52 (55.9%) had excellent efficacy, and 18 (19.4%) were cured, and the total efficacy was 100%. One year after the surgery, the surgical outcomes of 65 patients were reviewed, and the surgeries were ineffective in four (6.2%), effective in 14 (21.5%), very effective in 36 (55.4%), and curative in 11 (16.9%), and the total efficacy was 93.8%. Another 93 cases were treated with the traditional UPPP method only. At the six-month postoperative review, 18 (19.4%) were effectively cured, 30 (32.3%) had excellent efficacy, and 10 (10.8%) were cured, while the surgery was ineffective in 35 (37.6%). The total efficacy was 62.4%. One year after the surgery, the surgical outcomes of 75 patients were reviewed, and the surgeries were ineffective in 29 (38.7%), effective in 14 (18.7%), very effective in 24 (32.0%), and curative in eight (10.7%), and the total efficacy was 61.3%. Compared to the traditional operative methods, the treatment with one operation involving CO2-laser-assisted UPPP and selective nasal cavity expansion was thoroughly effective on multiple stenosis sites, including nasal, nasopharyngeal, and oropharyngeal airways. However, potential complications must be carefully avoided. PMID:26770642

    Introduction Surgical site infections (SSI) are a serious complication in vascular surgery which may lead to severe morbidity and mortality. Staphylococcus aureus nasal carriage is associated with increased risk for development of SSIs in central vascular surgery. The risk for SSI can be reduced by perioperative eradication of S. aureus carriage in cardiothoracic and orthopedic surgery. This study analyzes the relation between S. aureus eradication therapy and SSI in a vascular surgery population. Methods A prospective cohort study was performed, including all patients undergoing vascular surgery between February 2013 and April 2015. Patients were screened for S. aureus nasal carriage and, when tested positive, were subsequently treated with eradication therapy. The presence of SSI was recorded based on criteria of the CDC. The control group consisted of a cohort of vascular surgery patients in 2010, who were screened, but received no treatment. Results A total of 444 patients were screened. 104 nasal swabs were positive for S. aureus, these patients were included in the intervention group. 204 patients were screened in the 2010 cohort. 51 tested positive and were included in the control group. The incidence of S. aureus infection was 5 out of 51 (9.8%) in the control group versus 3 out of 104 in the eradication group (2.2%; 95% confidence interval 0.02–1.39; P = 0.13). A subgroup analysis showed that the incidence of S. aureus infection was 3 out of 23 (13.0%) in the control group in central reconstructive surgery versus 0 out of 44 in the intervention group (P = 0.074). The reduction of infection pressure by S. aureus was stronger than the reduction of infection pressure by other pathogens (exact maximum likelihood estimation; OR = 0.0724; 95% CI: 0.001–0.98; p = 0.0475). Conclusion S. aureus eradication therapy reduces the infection pressure of S. aureus, resulting in a reduction of SSIs caused by S. aureus. PMID:27529551

  17. The nasal distribution of metered dose inhalers.

    Newman, S P; Morén, P F; Clarke, S W

    1987-02-01

    The intranasal distribution of aerosol from a metered dose inhaler has been assessed using a radiotracer technique. Inhalers were prepared by adding 99Tcm-labelled Teflon particles (simulating the drug particles) to chlorofluorocarbon propellants, and scans of the head (and chest) taken with a gamma camera. Ten healthy subjects (age range 19-29 years) each performed two radioaerosol studies with the inhaler held in two different ways: either in a single position (vial pointing upwards) or in two positions (vial pointing upwards and then tilted by 30 degrees in the sagittal plane). The vast majority of the dose (82.5 +/- 2.8 (mean +/- SEM) per cent and 80.7 +/- 3.1 per cent respectively for one-position and two-position studies) was deposited on a single localized area in the anterior one-third of the nose, the initial distribution pattern being identical for each study. No significant radioaerosol was detected in the lungs. Only 18.0 +/- 4.7 per cent and 15.4 +/- 4.1 per cent of the dose had been removed by mucociliary action after 30 minutes, and it is probable that the remainder had not penetrated initially beyond the vestibule. Since the deposition pattern was highly localized and more than half the dose probably failed to reach the turbinates it is possible that the overall effect of nasal MDIs is suboptimal for the treatment of generalized nasal disorders.

    1994-11-01

    In the present paper we report two cases of "necrotizing sialometaplasia" in uncommon locations. The relevant literature is reviewed. Necrotizing sialometaplasia is self-limiting and is characterized by necrosis and squamous pseudohypertrophy. Typically occurring in the minor salivary glands of the oral mucosa, our cases appear to be the sixth and seventh cases of involvement of the nasal cavity reported in the literature. Owing to the similarity of histological findings, the term "sialometaplasia" is also used for this disorder. This rare disease is a benign process but may be misdiagnosed as mucoepidermoid or squamous cell carcinoma. Therefore, the possibility of this disease in the nose should again be presented. Both of our cases show that with a histological examination considering defined morphological findings, the diagnosis of necrotizing sialometaplasia can be verified and a diagnosis of a carcinoma can be excluded. Especially with regard to radical and possibly unnecessary invasive therapeutic procedures we emphasize the importance of considering "necrotizing sialometaplasia" as part of the differential diagnosis of nasal lesions.

    Relapsing polychondritis is a rare inflammation of cartilaginous tissues, the diagnosis of which is usually delayed by a mean period of 2.9 years from symptom onset. We present the case of a 36-year-old man with nasal pain and fever. Physical examination of the nose was grossly unremarkable, but there was significant tenderness of the nasal bridge. Acute sinusitis was initially diagnosed due to thickened left frontal sinus mucosa on computed tomography (CT); however, there was no improvement after antibiotic intake. Repeat CT showed edematous inflammation of the nasal septum; biopsy of this site demonstrated erosion and infiltration of lymphocytes, plasma cells, eosinophils, and neutrophils in the hyaline cartilage. Relapsing polychondritis was confirmed by the modified McAdam's criteria and can be diagnosed at an early stage by nasal septum biopsy; it should be considered as a differential diagnosis in patients presenting with nasal symptoms alone or persistent sinus symptoms.

    2006-01-01

    Nasal obstruction, a prominent feature of rhinitis, may be quantified in humans by haemodynamic techniques (measuring local blood flux), static methods (measuring the geometry of nasal cavities) and dynamic methods (assessing the patency of nasal airways through the measure of resistance to air flow). These methods demonstrated the nasal decongestant activity of xylometazoline in healthy volunteers and rhinitis patients. Controlled double-blind studies established the clinical efficacy of xylometazoline in infectious and allergic (seasonal and perennial) rhinitis versus placebo and in comparison with various reference substances. The effects on nasal epithelium ciliary activity which are observed in vitro are modest and even less pronounced in vivo owing to dilution in situ and protective physiological processes.

  1. Outpatient commitment and procedural due process.

    A large empirical literature on Kendra's Law has assessed the impact of court ordered outpatient treatment on outcomes such as treatment adherence, psychiatric hospitalization, quality of life, and treatment costs. Missing from the empirical literature, however, is a better understanding of procedural due process under Kendra's Law. Procedural due process concerns the safeguards that must be in place when governments deprive persons of their liberties, for example--notice, the right to a hearing and the right to appeal. This article reports the findings from a qualitative study of procedural due process and assisted outpatient treatment hearings under Kendra's Law.

    Between March 1990 and August 1997, outpatient endoscopic balloon dilation was performed for oesophageal strictures which developed secondary to malignancies, peptic strictures, post surgical narrowing, achalasia cardia, corrosive ingestion and other causes. A total of 169 dilations were performed in the 92 cases with an average of 1.8 dilation/case (Range 1 to 8). Dilation was possible in all 92 cases without the need for fluoroscopic monitoring. Twenty three (13.6%) of the dilations were performed using pneumatic balloon while in 146(86.4%) cases wire guided metal olives were used. There were nine minor complications which were treated with medication on an outpatient basis and four major complications which required inpatient care. Three of these had perforation of the oesophagus and one died. One other patient developed aspiration pneumonia and subsequently died.

  3. Primary prophylaxis of VTE in cancer outpatients.

    Cancer patients have a significantly higher risk of developing venous thromboembolism (VTE) compared to non-cancer patients and several studies suggest that VTE risk among ambulatory cancer patients varies widely. Recently, predictive models capable of risk-stratifying a broad range of ambulatory cancer outpatients have been developed and validated; using the Khorana model a score of 2 is associated with an intermediate-high risk for VTE. However, the use of VTE prophylaxis in ambulatory patients who have cancer remains controversial. Even if important randomized clinical trials showed decreased rates of VTE events among patients who were receiving chemotherapy, the effect of prophylaxis on morbidity, mortality, and costs has not been rigorously studied. Outpatients with active cancer should be assessed for thrombosis risk and although most do not routinely require thromboprophylaxis, it should be considered for high risk patients.

    Percutaneous renal biopsy (PRB) is a safe and effective tool in the diagnosis and management of renal disease. It is the gold standard for evaluating renal parenchymal disease. It is both useful for diagnosis and monitoring progress of renal diseases. Where facilities and personnel are available to carry out the procedure in developing countries, it has become increasingly difficult for patients to pay for hospital admission fees, the procedure, and processing of the samples obtained. Information on the success rate and safety of the procedure is of interest to nephrologists for cost-benefit considerations and medicolegal purposes. This paper reports the outcome of outpatient PRB done among patients of the University College Hospital, Ibadan, Nigeria. With the use of ultrasound guidance, PRB remains a safe procedure and can be done on an outpatient basis. PMID:15481751

    Rectally administered methohexital is a safe, effective sedative to ameliorate the stress of the surgical experience for the uncooperative child. The rapid onset, relatively short duration, and patient acceptance of this technique make it applicable for many pediatric outpatient procedures. Induction doses of 20-30 mg/kg of a 10% methohexital solution can produce sleep in 7-8 minutes. In some situations, the rectal route of administration has advantages over more commonly used techniques. PMID:2096749

    Venous thromboembolic disease which includes both venous thrombosis and pulmonary embolism, is a frequent and potentially fatal disease. Based on the introduction of low-molecular-weight heparins (LMWH) into practice it has been proved that outpatient treatment of venous thrombosis is effective and safe for a large number of patients with VTE. The growing volume of data on LMWH outpatient treatment in recent years shows that up to 50 % of patients with clinically stable pulmonary embolism can be treated at home. In spite of these facts home treatment of pulmonary embolism has not been established as part of common practice as yet. If we were to summarize the conditions for home treatment, we would consider outpatient care for patients at low risk based on auxiliary criteria, free from hemodynamic instability (primarily without a shock state), free from right ventricular failure, prior chronic heart or lung disease, serious comorbidities (gastrointestinal tract disease, kidney disease, blood diseases, advanced cancers), at low risk of early thromboembolism recurrence, free from other indications for hospitalization (pain requiring parenteral analgesics, infections etc.), at low risk of bleeding and with guaranteed patients cooperation and well-organized home care.

    In this study, the effects of nasal drug delivery device and the spray nozzle orientation on sprayed droplets deposition in a realistic human nasal cavity were numerically studied. Prior to performing the numerical investigation, an in-house designed automated actuation system representing mean adults actuation force was developed to produce realistic spray plume. Then, the spray plume development was filmed by high speed photography system, and spray characteristics such as spray cone angle, break-up length, and average droplet velocity were obtained through off-line image analysis. Continuing studies utilizing those experimental data as boundary conditions were applied in the following numerical spray simulations using a commercially available nasal spray device, which was inserted into a realistic adult nasal passage with external facial features. Through varying the particle releasing direction, the deposition fractions of selected particle sizes on the main nasal passage for targeted drug delivery were compared. The results demonstrated that the middle spray direction showed superior spray efficiency compared with upper or lower directions, and the 10µm agents were the most suitable particle size as the majority of sprayed agents can be delivered to the targeted area, the main passage. This study elaborates a comprehensive approach to better understand nasal spray mechanism and evaluate its performance for existing nasal delivery practices. Results of this study can assist the pharmaceutical industry to improve the current design of nasal drug delivery device and ultimately benefit more patients through optimized medications delivery.

    OBJECT In an era of escalating health care cost and universal pressure of improving 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 is rapidly increasing with an expanding aging population. While ASCs offer cost advantages for ACDF, there is a scarcity of evidence that ASCs allow for equivalent quality and thus superior health care value. Therefore, the authors analyzed a nationwide, prospective quality improvement registry (National Surgical Quality Improvement Program [NSQIP]) to compare the quality of ACDF surgery performed in the outpatient ASC versus the inpatient hospital setting. METHODS Patients undergoing ACDF (2005-2011) were identified from the NSQIP database based on the primary Current Procedural Terminology codes. Patients were divided into 2 cohorts (outpatient vs inpatient) based on the acute care setting documented in the NSQIP database. All 30-day surgical morbidity and mortality rates were compared between the 2 groups. Propensity score matching and multivariate logistic regression analysis were used to adjust for confounding factors and to identify the independent association of outpatient ACDF with perioperative outcomes and morbidity. RESULTS A total of 7288 ACDF cases were identified (inpatient = 6120, outpatient = 1168). Unadjusted rates of major morbidity (0.94% vs 4.5%, p < 0.001) and return to the operating room (OR) within 30 days (0.3% vs 2.0%, p < 0.001) were significantly lower in outpatient versus inpatient ACDF. After propensity matching 1442 cases (inpatient = 650, outpatient = 792) based on baseline 32 covariates, rates of major morbidity (1.4% vs 3.1%, p = 0.03), and return to the OR (0.34% vs 1.4%, p = 0.04) remained significantly lower after outpatient ACDF. Adjusted comparison using multivariate logistic regression demonstrated that ACDF

    Background Orbital complications following functional endoscopic sinus surgery (FESS) are fortunately rare. They are usually easily and rapidly recognizable. Case presentation We present an unusual case of a forty-five year old woman who underwent routine FESS and was not packed nasally after the procedure. Six hours later she started bleeding and nasal packs were inserted. She soon developed unilateral periorbital bruising and within hours her condition had worsened so much that the viability of the eye was thrown into question. She underwent medial and lateral canthotomies and made an uneventful post-operative recovery. Conclusion This rare case demonstrates that late, brisk post-operative bleeding can occur after FESS with potentially catastrophic consequences. Clinicians should be aware that discharging patients after FESS too early may lead to medico-legal problems. PMID:16734910

    Background Outpatient surgery is increasingly delivered at freestanding ambulatory surgery centers (ASCs), which are thought to deliver quality care at lower costs per episode. The objective of this study was to understand potential facilitators and/or barriers to the introduction of freestanding ASCs in the United States. Methods This is an observational study conducted from 2008–2010 using a 20% sample of Medicare claims. Potential determinants of ASC dissemination, including population, system, and legal factors, were compared between markets that always had ASCs, never had ASCs, and those that had new ASCs open during the study. Multivariable logistic regression was used to determine characteristics of markets associated with the opening of a new facility in a previously naïve market. Results New ASCs opened in 67 previously naïve markets between 2008 and 2010. ASCs were more likely to open in HSAs that were urban (adjusted OR 4.10; 95% CI 1.51–10.96), had higher per capita income (adjusted OR 3.83; 95% CI 1.43–10.45), and had less competition for outpatient surgery (adjusted OR 2.13; 95% CI 1.02–4.45). Legal considerations and latent need, as measured by case volumes of hospital-based outpatient surgery in 2007, were not associated with the opening of a new ASC. Conclusions Freestanding ASCs opened in advantageous socioeconomic environments with the least amount of competition. Because of their associated efficiency advantages, policymakers might consider strategies to promote ASC diffusion in disadvantaged markets to potentially improve access and reduce costs.

    Summary: The nose is a functionally complex organ implicated in breathing, olfaction, and phonation, with a critical role also in the aesthetic appearance of a person. This latter aspect should be carefully considered whenever a total or subtotal rhinectomy is performed for resection of locally advanced nasal cancer. To reconstruct large nasal defects, several techniques were described, including the use of cartilaginous grafts, bony grafts, local flaps, and free flaps. In cases of extensive full-thickness resections, free flaps probably represent the most adequate option. The aim of this report is to present the functional and aesthetical outcomes of a reconstruction of the nose after rhinectomy, using the medial femoral condyle free flap associated with the forehead flap.

    Objectives Although the public health significance of influenza in regions with a temperate climate has been widely recognized, information on influenza burden in tropical countries, including the Philippines, remains limited. We aimed to estimate influenza incidence rates for both outpatients and inpatients then characterized their demographic features. Design An enhanced surveillance was performed from January 2009 to December 2011 in an urbanized highland city. The influenza-like illness (ILI) surveillance involved all city health centers and an outpatient department of a tertiary government hospital. The severe acute respiratory infection (sARI) surveillance was also conducted with one government and four private hospitals since April 2009. Nasal and/or oropharyngeal swabs were collected and tested for influenza A, influenza B, and respiratory syncytial virus. Results and Conclusions We obtained 5915 specimens from 13 002 ILI cases and 2656 specimens from 10 726 sARI cases throughout the study period. We observed year-round influenza activity with two possible peaks each year. The overall influenza detection rate was 23% in the ILI surveillance and 9% in the sARI surveillance. The mean annual outpatient incidence rate of influenza was 5·4 per 1000 individuals [95% confidence interval (CI), 1·83–12·7], and the mean annual incidence of influenza-associated sARI was 1·0 per 1000 individuals (95% CI, 0·03–5·57). The highest incidence rates were observed among children aged <5 years, particularly those aged 6–23 months. Influenza posed a certain disease burden among inpatients and outpatients, particularly children aged <5 years, in an urbanized tropical city of the Philippines. PMID:24393336

    The antimicrobial proteins lactoferrin (Lf) and lysozyme (Ly) are invariably found in nasal secretions. To investigate the cellular sources and the secretory control of these nasal proteins in vivo, 34 adult subjects underwent nasal provocation tests with methacholine (MC), histamine (H), and gustatory stimuli. Nasal lavages were collected and analyzed for total protein (TP), albumin (Alb), Lf, and Ly. MC (25 mg), H (1 mg), and gustatory stimuli (spicy foods) all increased the concentrations of TP, Alb, Lf, and Ly. However, when each protein was assessed as a percentage of TP (i.e., Alb% = Alb/TP; Lf% = Lf/TP; Ly% = Ly/TP), MC and gustatory stimuli, which both induce glandular secretion, selectively augmented Lf% and Ly% without changing Alb%, while H, which primarily increases vascular permeability, increased Alb% without significantly affecting Lf% or Ly%. Gel electrophoresis and immunoblotting analysis of nasal secretions demonstrated both Lf and Ly in cholinergically induced secretions. Furthermore, histochemical analyses of nasal turbinate tissue revealed Lf and Ly colocalization within the serous cells of submucosal glands, providing evidence that both proteins are strictly glandular products within the nasal mucosa. Therefore, both Lf and Ly are produced and secreted from the glands, and their secretion may be pharmacologically regulated in attempts to improve host defenses. Images PMID:2681268

    A 21-year-old man presented with nasal obstruction of the right nasal fossa of 1 year duration. Nasal endoscopy revealed in the right inferior turbinate head a rounded neoplasm about 1 cm in diameter. Cytologic study of a nasal scraping specimen disclosed numerous clusters containing columnar cells with cytomegaly, prominent multinucleation, markedly sparse shortened cilia; the cytoplasm contained an acidophil area and a small round area that stained poorly; cells with a large intracytoplasmic vacuole that was acidophil and PAS+. Serology tests using the nested polymer chain reaction (PCR) technique on serum, nasal and pharyngeal smears revealed an Epstein-Barr virus (EBV) infection that was confirmed at electron microscopy. The clinical and cytological features resolved 19 months after the initial evaluation. Conclusion The authors advise carrying out clinical (endoscopy, serology, etc.) evaluation of all endonasal neoplasms and to routinely perform cytological study on nasal scraping specimens. When samples test positive for EBV, nasal and nasopharyngeal endoscopy should be performed regularly to detect possible evidence for nasopharyngeal carcinoma (NPC). PMID:16451721

    In this study, the authors sought to address the relationships between measured indoor environmental factors and nasal patency (i.e., minimum cross-sectional area) and volume and markers of nasal inflammation in nasal lavage fluid. Clinical data were obtained for 115 females who worked at 36 geriatric nursing departments. The indoor climates in the nursing departments were characterized by high room temperatures (median = 23 degrees C), low relative air humidities (median = 24%), and high air exchange rates indicated by low carbon dioxide levels (median = 570 ppm). Evidence of microbial amplification was observed in the ventilation unit in 3 of the departments. Decreased nasal patency was observed relative to microbial amplification in the ventilation units (minimum cross-sectional area 1 = 0.80 cm2 vs. 0.64 cm2, p = .003, minimum cross-sectional area 2 = 0.80 cm2 vs. 0.67 cm2, p = .02) and in relation to elevated indoor temperature (volume 1 = 3.46 cm3 vs. 3.22 cm3, p = .03). The authors concluded that the indoor environment may have affected the nasal mucosa of nursing personnel, thus causing nasal mucosal swelling. The results support the view that fungal contamination of air-supply ducts may be a source of microbial pollution, which can affect the nasal mucosa.

    1980-10-01

    The switching point from nasal to oronasal breathing during incrementally graded submaximal exercise was determined in 30 (14 M, 16 F) healthy adult volunteers. Nasal airflow was measured by a pneumotachograph attached to a nasal mask. Oral airflow was determined as the difference between nasal airflow and total pulmonary airflow, the latter being measured by a head-out exercise body plethysmograph. The airflow and pressure signals were sampled every 20 msec by a micropressor, which calculated respiratory volumes and nasal work of breathing, and produced an on-line print-out. Twenty of the 30 subjects (normal augmenters) switched from nasal to oronasal breathing at submaximal exercise of 105.0 W (SD = 30.1), four subjects (mouth breathers) breathed habitually oronasally, five subjects (nose breathers) persistently breathed through the nose only, and one subject showed no consistent nose/mouth breathing pattern. In normal augmenters, the onset of oronasal breathing (VE 35.3 +/- 10.81 . min-1) was quite consistent individually, but varied considerably between inividuals without showing a significant sex difference. The factors most closely related to the switching point were rating of perceived exertion of breathing and nasal work of breathing. PMID:7444224

    Respiratory viral infections may worsen bronchial hyperreactivity. However, there is no data on the possible role of recurrent infectious rhinitis in nose hyperreactivity. This study was therefore designed to investigate whether subjects suffering from recurrent common cold have nasal hyperreactivity, assessed by histamine nasal challenge. This study included a group of 40 patients (19 males, mean age 34.1 years) with history of at least five episodes of common cold in the previous year, but without documented allergy, and twenty healthy subjects (8 males, mean age 32.3 years) were enrolled as control group, all of whom were non-allergic. Nasal provocation test with histamine was performed in all subjects. Nasal provocation test with histamine induced a 200% increase in nasal resistance after provocation in 24 (60%) patients suffering from recurrent viral rhinitis. No normal subject had an increase >180% in nasal resistance. There was a significant difference between the patient group and the control group (p<0.05). In conclusion, this study shows that nasal hyperreactivity might be a sequela of recurrent common cold. Further studies should be conducted to confirm this preliminary finding.

  19. Inverted papillomas and benign nonneoplastic lesions of the nasal cavity

    2012-01-01

    Background: Benign lesions of the nasal cavity represent a diverse group of pathologies. Furthermore, each of these disorders may present differently in any given patient as pain and discomfort, epistaxis, headaches, vision changes, or nasal obstruction. Although these nasal masses are benign, many of them have a significant capacity for local tissue destruction and symptomatology secondary to this destruction. Advances in office-based endoscopic nasendoscopy have equipped the otolaryngologist with a safe, inexpensive, and rapid means of directly visualizing lesions within the nasal cavity and the initiation of appropriate treatment. Methods: The purpose of this study is to review the diagnosis, management, and controversies of many of the most common benign lesions of the nasal cavity encountered by the primary care physician or otolaryngologist. Results: This includes discussion of inverted papilloma (IP), juvenile angiofibroma, squamous papilloma, pyogenic granuloma, hereditary hemorrhagic telangiectasia, schwannoma, benign fibro-osseous lesions, and other benign lesions of the nasal cavity, with particular emphasis on IP and juvenile angiofibroma. Conclusion: A diverse array of benign lesions occur within the nasal cavity and paranasal cavities. Despite their inability to metastasize, many of these lesions have significant capability for local tissue destruction and recurrence. PMID:22487294

    1986-01-01

    Fetal surgery has come of age. For decades experimental fetal surgery proved essential in studying normal fetal physiology and development, and pathophysiology of congenital defects. Clinical fetal surgery started in the 1960s with intrauterine transfusions. In the 1970s, the advent of ultrasonography revolutionized fetal diagnosis and created a therapeutic vacuum. Fetal treatment, medical and surgical, is slowly trying to fill the gap. Most defects detected are best treated after birth, some requiring a modification in the time, mode and place of delivery for optimal obstetrical and neonatal care. Surgical intervention in utero should be considered for malformations that cause progressive damage to the fetus, leading to death or severe morbidity; that can be corrected or palliated in utero with a reasonable expectation of normal postnatal development; that cannot wait to be corrected after birth, even considering pre-term delivery; that are not accompanied by chromosomal or other major anomalies. At present, congenital hydronephrosis is the most common indication for fetal surgery, followed by obstructive hydrocephalus. Congenital diaphragmatic hernia also fulfills the criteria, but its correction poses more problems, and no clinical attempts have been reported so far. In the future many other malformations or diseases may become best treated in utero. The ethical and moral issues are complex and need to be discussed as clinical and experimental progress is made.

    Well into the first decades of the 20th century, medical opinion held that any surgical attempts to treat heart disease were not only misguided, but unethical. Despite such reservations, innovative surgeons showed that heart wounds could be successfully repaired. Then, extracardiac procedures were performed to correct patent ductus arteriosus, coarctation of the aorta, and tetralogy of Fallot. Direct surgery on the heart was accomplished with closed commissurotomy for mitral stenosis. The introduction of the heart-lung machine and cardiopulmonary bypass enabled the surgical treatment of other congenital and acquired heart diseases. Advances in aortic surgery paralleled these successes. The development of coronary artery bypass grafting greatly aided the treatment of coronary heart disease. Cardiac transplantation, attempts to use the total artificial heart, and the application of ventricular assist devices have brought us to the present day. Although progress in the field of cardiovascular surgery appears to have slowed when compared with the halcyon times of the past, substantial challenges still face cardiac surgeons. It can only be hoped that sufficient resources and incentive can carry the triumphs of the 20th century into the 21st. This review covers past developments and future opportunities in cardiac surgery. PMID:22163121

    The nasal cavity and sinuses may be exposed primarily via a dorsal or ventral surgical approach. Surgical planning involves the use of advanced imaging, such as computed tomography or MRI. Surgical treatment of lesions of the nasal cavity usually is limited to benign lesions or can also be used in combination with adjunctive therapy, such as radiation therapy. Extreme caution must be exercised with a dorsal approach to the nasal cavity to avoid complications of inadvertent penetration into the brain case. Gentle tissue handling and careful closure of the mucoperiosteum must be exercised following a ventral approach to minimize the risk of oronasal fistula formation. PMID:27217006

    The recommendation to change breathing patterns from the mouth to the nose can have a significantly positive impact upon the general well being of the individual. We classify nasal and mouth breathing by using an acoustic sensor and intelligent signal processing techniques. The overall purpose is to investigate the possibility of identifying the differences in patterns between nasal and mouth breathing in order to integrate this information into a decision support system which will form the basis of a patient monitoring and motivational feedback system to recommend the change from mouth to nasal breathing.

    Healthy humans normally breathe through their nose even though its complex geometry imposes a significantly higher resistance in comparison with mouth breathing. The major functional roles of nasal breathing are defense against infiltrating particles and conditioning of the inspired air to nearly alveolar conditions in order to maintain the internal milieu of the lung. The state-of-the-art of the existing knowledge on nasal air-conditioning will be discussed in this review, including in vivo measurements in humans and computational studies on nasal air-conditioning capacity. Areas where further studies will improve our understanding and may help medical diagnosis and intervention in pathological states will be introduced. PMID:18565805

    A newborn infant with bilateral mucoceles of the lacrimal sacs also had submucosal masses along the floor of the nose beneath the inferior turbinates communicating with the mucoceles. Drainage of the mucoceles was performed by needle aspiration and wide marsupialization of the nasal masses into the nose under direct visualization. To our knowledge, this is the first time that intranasal extension of mucoceles has been reported, and the first time that lacrimal sac mucoceles have been successfully treated via direct nasal drainage. We advocate careful nasal evaluation in cases of congenital lacrimal sac mucoceles to determine whether intranasal extension is common and whether intranasal drainage can be curative.

    In a seris of 50 embryos and foetuses ranging from 20 mm to 190 mm in length two foetuses of 34 and 37 mm (48 to 50 days old) were found, that presented deformities of the septum of the cartilaginous nasal capsule, representing 4% of our material. The deformities consisted of curves of the nasal septum, located to both vomeronasal nerves. We therefore think that this study is interesting because it adds a new factor, the congenital one, to the etiology of deformities of the nasal septum.

    Myoepithelioma is a rare tumor, most frequently located in the salivary gland. Case reports of extra-salivary myoepithelioma are sporadic, with only one case in the nasal cavity. A 68-year-old male patient presented with a myoepithelioma of the nasal cavity manifesting as nasal obstruction and epistaxis, which was treated successfully with endoscopic excision. Histological examination revealed myoepithelial cells and myxoid stroma, which confirmed the diagnosis of myoepithelioma. The behavioral pattern is similar to if not identical with that of the mixed tumor, pleomorphic adenoma, which is benign, but the potential for recurrence is always present, especially if complete resection is not achieved.

    Although pleomorphic adenoma is the most common benign neoplasm of the salivary glands, it has also been reported to be present in the neck, ear, mediastinum, external nose and nasal cavity. Intranasal localization of this lesion is very rare and mainly originates from the nasal septum. From wherever the lesion originates, the main treatment modality should be surgical. We presented a very rare case of intranasal pleomorphic adenoma originated from the inferior nasal turbinate. Due to the expansile nature of the lesion, a midfacial degloving approach was preferred.

    Since ten years laparoscopic techniques have been employed as alternatives of many established open procedures in gynecologic, abdominal and finally urologic surgery. Laparoscopic techniques show significant advantages compared to open surgery, such as less hospitalization, reduced need of analgesic drugs, quick return to daily activities and far a better cosmetic results. Laparoscopic surgery has been advocated for urologic, uro-gynecologic and andrologic diseases. Since 1983 one-day surgery was proposed for only a few gynecologic and abdominal procedures and only recently for laparoscopic renal biopsy and abdominal testis evaluation. In these preliminary experiences the conditions for a correct management of laparoscopic one-day surgery have been clearly pointed out: 1. correct surgical indication; 2. through knowledge of surgical technique; 3. duration of the procedure less than 90 minutes; 4. correct anesthesia. Technique of anesthesia must be adapted to the surgical procedure required, its duration and the physical features of the patient. General anesthesia is usually preferred for either longer and more complex procedures or when a higher abdominal insufflation pressure is needed. Spinal or local anesthesia are preferred for simpler procedures or when only one trocar is required. At date only few urologic procedures seem to be suitable to one-day laparoscopic surgery. 1) Varicocele: although laparoscopic varicocelectomy in one-day surgery has never been reported previously, it can be performed in a short time, only 3 trocars are needed and insufflation pressure can be maintained within 15 mm Hg. 2) Renal biopsy and marsupialization of renal cysts. These are usually managed percutaneously but in some particular indications procedures under direct vision should be preferable. Both are short-lasting and only superficial general anesthesia is required; as surgical access is retroperitoneal only two trocars are sufficient; at date only renal biopsies have

    Preceding a endoscopic sinus surgery (ESS), we have proposed performing a submucosal partial-turbinectomy (SPT) which removes a part of the inferior nasal concha bone attached to maxillary sinus with an antrostomy. By this method, we could not only make a large antrostomy but also obtain good maneuverability by opening the middle nasal meatus in ESS. We performed SPT preceding ESS in 140 cases (261 sides) between January 2012 and June 2014. The stenosis rates of the middle nasal meatus were 14.2% (37 sides from 261 sides) in one month, 7.4% (18 sides from 243 sides) in three months and 3.7% (6 sides from 163 sides) in 6 months after surgery. The closing rates of the antrostomy were 1.5% (4 sides from 261 sides) in one month, 2.9% (7 sides from 243 sides) in three months and 6.7% (11 sides from 163 sides) in 6 months after surgery. We considered that the SPT method would contribute to secure sufficient ventilation routes for wound healing of sinusitis following surgery on the mucous membrane. In addition, the SPT method has merit from the point of deceasing risks of atrophic rhinitis and empty nose syndrome by preserving most of the inferior nasal concha.

  15. Olfaction in Endoscopic Sinus and Skull Base Surgery.

    Olfactory dysfunction is a common complaint for patients with chronic rhinosinusitis, because smell loss decreases a patient's quality of life. Smell loss is caused by obstruction from polyps, nasal discharge, and mucosal edema, as well as inflammatory changes within the olfactory epithelium. Addressing olfaction before endoscopic sinus and skull base surgery is important in order to set postoperative expectations, because an improvement in smell is difficult to predict. Several commercially available olfactory testing measures are available and can easily be administered in clinic. During surgery, careful dissection within the olfactory cleft is recommended in order to optimize postoperative olfactory function.

    In recent decades there have been significant legislative changes in Spain. Society develops faster than laws, however, and new challenges have emerged. In 2004, the Spanish Association of Relatives of the Mentally Ill (FEAFES) proposed amending the existing legislation to allow for the implementation of involuntary outpatient treatment (IOT) for patients with severe mental illness. Currently, and after having made several attempts at change, there is no specific legislation governing the application of this measure. Although IOT may be implemented in local programmes, we consider legal regulation to be needed in this matter.

    Pulmonary rehabilitation has become a standard of care for patients with chronic lung disease. It has been clearly demonstrated that pulmonary rehabilitation improves exercise capacity and quality of life in patients with chronic lung disease and reduces the number of hospital days and other measures of health-care utilization in patients with chronic obstructive pulmonary disease (COPD). This is an update of the guidelines in outpatient pulmonary rehabilitation in Austria, closely related to the official American Thoracic Society and European Respiratory Society Statement published in 2013.The guidelines represent standards of quality for requirements of structural and personal qualifications.

    Compulsory outpatient treatment (co-pt) has been possible in Denmark since 2010. The aim is to secure necessary treatment, reduce involuntary commitment and improve quality of life for patients with a severe psychiatric illness. Co-pt has been brought into use in 33 cases. This case report describes a patient with paranoid schizophrenia who several times developed severe psychotic symptoms shortly after discharge due to lack of compliance with treatment. Within one year of co-pt the patient was not admitted to hospital and improved in overall functioning. After terminating co-pt the patient rapidly deteriorated into psychotic relapse.

    Formaldehyde is a nasal carcinogen in rodents at high doses and is an endogenous compound that is present in all living cells. Due to its high solubility and reactivity, quantitative risk estimates for inhaled formaldehyde have relied on internal dose estimates in the upper respiratory tract. Dosimetry calculations are complicated by the presence of endogenous formaldehyde concentrations in the respiratory mucosa. Anatomically accurate computational fluid dynamics (CFD) models of the rat, monkey, and human nasal passages were used to simulate uptake of inhaled formaldehyde. An epithelial structure was implemented in the nasal CFD models to estimate formaldehyde absorption from air:tissue partitioning, species-specific metabolism, first-order clearance, DNA binding, and endogenous formaldehyde production. At an exposure concentration of 1 ppm, predicted formaldehyde nasal uptake was 99.4, 86.5, and 85.3% in the rat, monkey, and human, respectively. Endogenous formaldehyde in nasal tissues did not significantly affect wall mass flux or nasal uptake predictions at exposure concentrations > 500 ppb; however, reduced nasal uptake was predicted at lower exposure concentrations. At an exposure concentration of 1 ppb, predicted nasal uptake was 17.5 and 42.8% in the rat and monkey; net desorption of formaldehyde was predicted in the human model. The nonlinear behavior of formaldehyde nasal absorption will affect the dose-response analysis and subsequent risk estimates at low exposure concentrations. Updated surface area partitioning of nonsquamous epithelium and average flux values in regions where DNA-protein cross-links and cell proliferation rates were measured in rats and monkeys are reported for use in formaldehyde risk models of carcinogenesis.

    Objective To describe and analyze the results of a public-private partnership between the Ministry of Health and a private hospital in a project of assistance and scientific research in the field of endovascular surgery. Methods: The flows, costs and clinical outcomes of patients treated in a the public-private partnership between April 2012 and July 2013 were analyzed. All patients underwent surgery and stayed at least one day at the intensive care unit of the private hospital. They also participated in a research protocol to compare two intravenous contrast media used in endovascular surgery (iodinated contrast and carbon dioxide). Results A total of 62 endovascular procedures were performed in 57 patients from the public healthcare system. Hospital and endovascular supplies expenses were significantly higher as compared to the amount paid by the Unified Health System (SUS - Sistema Único de Saúde) in two out of three disease groups studied. Among outpatients, the average interval between appointment and surgery was 15 days and, in hospitalized patients 7 days. All procedures were successful with no conversion to open surgery. The new contrast medium studied - carbon dioxide – was effective and cheaper. Conclusion The waiting time for patients between indication and accomplishment of surgery was significantly reduced. Public-private partnerships can speed up care of patients from public health services, and generate and improve scientific knowledge. PMID:25295457
