Oral cancers in association with trismus are commonly seen in clinical practice. Such a situation deserves special attention as it may complicate the tumour-ablative surgery and interfere with postoperative cancer surveillance. It follows that the simultaneous tackling of oral cancer and trismus should be pursued at any rate. In this presentation, a novel surgical approach using a cross-cheek anterolateral thigh (ALT) flap is introduced. With the special design in length, shape and orientation, this flap is capable of closing a wider defect area, sometimes extending across two functional regions (viz., posterior palate and trigonal area) without resort to two free flaps. As such, complex defects resulting from trismus release and tumour ablation can be readily repaired in a single stage. The advantages of such a technique include abundance in soft-tissue resources, proper flap quality and thickness, reliable blood supply, long and sizeable pedicle, ease in flap inset, need for only one recipient rather than two and the eradication of large area of mucosa that is predisposed to malignant transformation. The favourable outcome implicates that this innovative design could be a viable option in the management of such a clinical problem. Copyright (c) 2009. Published by Elsevier Ltd.

The aim of this review was to compare systematically the subjective measure of trismus between different interventions to treat head and neck cancer, particularly those of the oropharynx. Using The Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) Guidelines, Six databases were searched for the text using various terms which include "oropharyngeal/head and neck cancer", "trismus/mouth opening" and the various treatment modalities. Included in the review were clinical studies (> or =10 patients). Three observers independently assessed the papers identified. Among the six studies reviewed, five showed a significantly worst outcome with regard to the quality-of-life questionnaire scores for a radiotherapy or surgery and radiotherapy (RT) ± chemotherapy or chemoradiotherapy when compared to surgery alone. Only one study showed no significant difference between surgery alone and other treatment modalities. Subjective quality-of-life measures are a concurrent part of modern surgical practice. Although subjective measures were utilised to measure post operative trismus successfully, there was no consensus as to which treatment modality had overall better outcomes, with conflicting studies in keeping with the current debate in this field. Larger and higher quality studies are needed to compare all three treatment modalities.

This study investigated the clinical effectiveness of intervention with an open-mouth exercise device designed to facilitate maximal interincisal opening (MIO) and improve quality of life in patients with head and neck (H&N) cancer and oral submucous fibrosis (OSF). Sixty patients with H&N cancer, OSF, and trismus (MIO < 35 mm) participated in the functional rehabilitation program. An open-mouth exercise device intervention group and conventional group, each consisting of 20 patients, underwent a 12-week training and exercising program and follow-up. For the control group, an additional 20 patients were randomly selected to match the demographic characteristics of the aforementioned two groups. The patients' MIO improvements in the aforementioned three groups were 14.0, 10.5, and 1.3 mm, respectively. Results of this study confirm the significant improvement in average mouth-opening range. In addition, according to patient feedback, significant improvements in health-related quality of life and reductions in trismus symptoms occurred in the open-mouth exercise device group. This newly designed open-mouth exercise device can facilitate trismus patients with H&N cancer and OSF and improve mouth-opening range and quality of life.

The purpose of this study was to evaluate the effect of low-level laser therapy (LLLT) on postoperative trismus and edema after the removal of mandibular third molars. Thirty-two patients who were to undergo surgical removal of lower third molars were studied. Patients were randomly allocated to two groups, LLLT and placebo. Patients in the LLLT group received 12 J (4 J/cm(2)) low-level laser irradiation to the operative side intraorally 1 cm from the target tissue, and to the masseter muscle extraorally immediately after surgery. In the placebo group the handpiece was inserted into the operative side intraorally and was applied to the masseter muscle extraorally each for 1 min, but laser power was not activated. Inter-incisal opening and facial swelling were evaluated on postoperative days 2 and 7. Student's t-test used to analyze the data. It was determined that the trismus and the swelling in LLLT group were significantly less than in the placebo group on postoperative days 2 and 7. Within the limitations of this study it can be concluded that LLLT can be beneficial for the reduction of postoperative trismus and swelling after third molar surgery.

The authors present a case of Chiari malformation manifesting as isolated trismus, describe the typical symptoms associated with Chiari malformation, and discuss the potential anatomical causes for this unique presentation. A 3-year-old boy presented with inability to open his jaw for 6 weeks with associated significant weight loss. The results of medical and radiological evaluation were negative except for Type I Chiari malformation with cerebellar tonsils 12 mm below the level of the foramen magnum. The patient underwent Chiari decompression surgery. Postoperatively, his ability to open his mouth was significantly improved, allowing resumption of a regular diet. Postoperative MRI revealed almost complete resolution of the syringobulbia. To the best of the authors' knowledge, this is the first reported case of isolated trismus from Chiari malformation with syringobulbia.

The purpose of this study is to compare the effects of extraoral and intraoral low-level laser therapies (LLLT) on postoperative trismus and oedema following the removal of mandibular third molars. Forty-eight patients who were to undergo surgical removal of their lower third molars were studied. Patients were randomly allocated to one of three groups: extraoral LLLT, intraoral LLLT, or placebo. In the study, a Ga-Al-As diode laser device with a continuous wavelength of 808 nm was used, and the laser therapy was applied by using a 1 x 3-cm handpiece. The flat-top laser beam profile was used in this therapy. For both of the LLLT groups, laser energy was applied at 100 mW (0.1 W) for a total of 120 s (0.1 W x 120 s = 12 J). Patients in the extraoral-LLLT group (n = 16) received 12-J (4 J/cm(2)) low-level laser irradiation, and the laser was applied at the insertion point of the masseter muscle immediately after the operation. Patients in the intraoral-LLLT group (n = 16) received 12-J (4 J/cm(2)) low-level laser irradiation intraorally at the operation site 1 cm from the target tissue. In the placebo group (n = 16), the handpiece was inserted intraorally at the operation site and then was touched extraorally to the masseter muscle for 1 min at each site (120 s total), but the laser was not activated. The size of the interincisal opening and facial swelling were evaluated on the second and seventh postoperative days. At the second postoperative day, trismus (29.0 +/- 7.6 mm [p = 0.010]) and swelling (105.3 +/- 5.0 mm [p = 0.047]) in the extraoral-LLLT group were significantly less than in the placebo group (trismus: 21.1 +/- 7.6 mm, swelling: 109.1 +/- 4.4 mm). Trismus (39.6 +/- 9.0 mm [p = 0.002]) in the extraoral-LLLT group at the seventh postoperative day was also significantly less than in the placebo group (29.0 +/- 6.2 mm). However, at the seventh postoperative day in the intraoral-LLLT group, only trismus (35.6 +/- 8.5 [p = 0.002]) was significantly less than in the placebo group (29.0 +/- 6.2 mm). This study demonstrates that extraoral LLLT is more effective than intraoral LLLT for the reduction of postoperative trismus and swelling after extraction of the lower third molar.

Pain, swelling, and trismus are the most common complications after surgical removal of impacted lower third molars. The aim of this study was to evaluate the analgesic and anti-inflammatory effects of a low-level laser therapy (Laser Smile™, Biolase®, San Clemente, USA) applied to the wound appeared after the surgical removal of impacted lower third molars. A prospective, randomized, and double-blind study was undertaken in 20 healthy patients with two symmetrically impacted lower third molars. The application of a low-level laser was made randomly on one of the two sides after surgery. The experimental side received 5 J/cm(2) of energy density, a wavelength of 810 nm, and an output power of 0.5 W. On the control side, a handpiece was applied intraorally, but the laser was not activated. Evaluations of postoperative pain, trismus, and swelling were made. The sample consisted of 11 women and nine men, and mean age was 23.35 years (18-37). The pain level in the first hours after surgery was lower in the experimental side than in the placebo side, although without statistically significant differences (p = 0.258). Swelling and trismus at the 2nd and 7th postoperative days were slightly higher in the control side, although not statistically significant differences were detected (p > 0.05). The application of a low-level laser with the parameters used in this study did not show beneficial affects in reducing pain, swelling, and trismus after removal of impacted lower third molars.

Objectives: To compare the three non-steroidal anti-inflammatory agents (NSAIDs) diclofenac potassium, etodolac and naproxen sodium in relation to pain, swelling and trismus following impacted third molar surgery. Study Design: The study was a randomized and a double-blinded study which included 42 healthy young individuals with impacted third molars and bone retention. Patients were randomly assigned to 3 groups (n: 14) to which diclofenac potassium, naproxen sodium and etodolac were administered orally an hour before the operation. Impacted third molars were surgically extracted with local anaesthesia. Visual analog scales (VAS) were used to assess the pain in the 6th, 12th hours and on the 1st, 2nd, 3rd, 5th, and 7th days postoperatively. Swelling was evaluated using ultrasound (US) and mouth opening (trismus) was measured with a composing stick pre and post operatively on the 2nd and 7th days respectively. Results: Regarding pain alleviation, diclofenac potassium was better than naproxen sodium and naproxen sodium was better than etodolac but these differences were not statistically significant. US measurements showed that the swelling on postoperative 2nd day was significantly lowest with diclofenac potassium as compared to others (p= 0.027) while naproxen sodium and etodolac acted similarly (p=0.747). No difference was noted regarding trismus in any of the groups. Conclusions: NSAIDs (diclofenac, naproxen and etodolac) are somehow similarly effective for controlling pain and trismus following extraction of mandibular third molars but diclofenac potassium surpasses others in reduction of swelling. Key words:Diclofenac potassium, naproxen sodium, etodolac, impacted third molar surgery, pain, swelling, trismus. PMID:24316711

Radiation-induced temporo-mandibular joint disorder in post-radiotherapy nasopharyngeal carcinoma patients: assessment and treatment.

PubMed

Wu, Vincent W C; Lam, Ying-Na

2016-06-01

Nasopharyngeal carcinoma (NPC) is endemic in southern China, and its incidence in Hong Kong is relatively high. Radiotherapy is the mainstay treatment for NPC due to its relatively high radiosensitivity and deep-seated anatomical position, which is not readily accessible by surgery. Although the technique of radiotherapy in NPC has been advancing and offers promising treatment outcome, complications around the irradiation areas are inevitable and the quality of life of the post-radiotherapy patients is often compromised. Trismus, which is defined as the restricted mouth opening or jaw movement due to the disorder of temporo-mandibular joint (TMJ), is one of the possible late complications for radiotherapy of NPC and is found in 5-17% of the post-radiotherapy (post-RT) patients. Trismus at early stage may only affect the speech, but in severe cases nutritional intake and oral hygiene condition may deteriorate seriously. This article reviewed the possible causes of radiation-induced TMJ damage, the various assessments including imaging modalities and possible treatments. The conclusion is that the availability of simple, yet effective examinations for trismus is essential for delaying the progression and restoring TMJ functions. Although there is no absolutely effective treatment for trismus, many supportive, restorative and palliative management are possible under different clinical situations.

Sectional mandibular complete denture for a total maxillectomy patient with trismus: a clinical report.

Celakil, Tamer; Demir, Azize; Keskin, Haluk

2017-01-01

This report presents the case of a 60-year-old male patient with trismus induced by radiotherapy and fabrication of a sectional mandibular complete denture to allow the insertion of the denture into the mouth. A mandibular sectional denture was designed in two pieces with a locking mechanism by using mini anchor and ball abutment housing with cap. Patients who have undergone maxillectomy often have constricted mouth openings, as a result of surgical intervention and radiotherapy, and complain of an inability to insert or remove dentures. A new approach is vital for sectional dentures because existing sectional denture fabrication techniques cannot meet the ongoing needs of trismus patients. The mini anchor system with ball abutment housing has better mechanical retention in acrylic resin and can provide favorable stabilization during masticatory function; thus, additional framework is not required for assisting in stabilization and retention.

An 8-month old, male, neutered bulldog was presented for investigation of a 2-day history of trismus. Endotracheal intubation was impossible as the dog was only able to open his mouth approximately 2 cm. A laryngeal mask airway was blindly inserted after induction of general anesthesia to maintain the patient on inhalational anesthesia and improve respiration for computed tomography and muscle biopsy. The dog recovered from anesthesia uneventfully. PMID:22942446

Due to their anatomical position, the surgical removal of impacted third molars results in oedema, pain, and trismus. The purpose of this study was to evaluate the efficacy of supraperiosteal injection of methylprednisolone compared with an oral tablet form and intravenous (i.v.) injection in the prevention of postoperative pain and oedema associated with inflammation. This randomized, prospective, and controlled study included 44 patients. The patients were randomly divided into four groups: group 1 (control; no steroids), group 2 (local injection), group 3 (oral tablets), and group 4 (i.v. injection). On days 2 and 7 following surgery, linear oedema was determined using facial landmarks, and maximal mouth opening was measured. Postoperative mouth opening and swelling were evaluated for each route of methylprednisolone administration and compared. The female (59%) to male (41%) ratio was 1.44; the mean age of the patients was 29.6 years. The level of significance was set at P<0.01 for mouth opening and P<0.05 for oedema. With regard to trismus, all three routes of administration demonstrated better efficacy in comparison to the control. While oral administration and i.v. injection of methylprednisolone achieved similar results, masseter injection provided better results in reducing oedema and trismus when compared to the control following lower third molar surgery.

The aim of this study was to investigate the effect of the submucosal injection of 1ml dexamethasone (4mg/ml) on pain, swelling, and trismus following the extraction of retained lower third molars. Ninety patients (mean age 23.5 years) were split randomly into three equal study groups (30 patients in each): the 'before' group received dexamethasone 15min before surgery and placebo 15min after surgery; the 'after' group received placebo 15min before surgery and dexamethasone 15min after surgery; the 'placebo' group received placebo 15min before surgery and placebo 15min after surgery. Postoperative pain was recorded by the patients using a visual analogue scale, numerical rating scale, and the McGill Pain Questionnaire at 1, 2, 4, 6, 8, 12, and 24h after surgery. The patients also recorded the total number of analgesic doses consumed during the 24h after the procedure. Swelling (determined using linear measurements of the face) and trismus (determined through measurement of maximum mouth opening) were assessed at 48h, 72h, and 7 days following surgery. Better control of pain, swelling, and trismus was demonstrated for dexamethasone in comparison to placebo. Postoperative dexamethasone provided better pain control than preoperative dexamethasone. There was no difference in total rescue analgesic intake between the preoperative and postoperative dexamethasone groups.

2015-06-15

Purpose: The aim of this study was to explore the use of Magnetic Resonance Imaging (MRI)-derived features as indicators of Radiotherapy (RT)-induced normal tissue morbidity. We also investigate the relationship between these features and RT dose in four critical structures. Methods: We demonstrate our approach for four patients treated with RT for base of tongue cancer in 2005–2007. For each patient, two MRI scans (T1-weighted pre (T1pre) and post (T1post) gadolinium contrast-enhancement) were acquired within the first six months after RT. The assessed morbidity endpoint observed in 2/4 patients was Grade 2+ CTCAEv.3 trismus. Four ipsilateral masticatory-related structures (masseter, lateralmore » and medial pterygoid, and the temporal muscles) were delineated on both T1pre and T1post and these scans were co-registered to the treatment planning CT using a deformable demons algorithm. For each structure, the maximum and mean RT dose, and six MRI-derived features (the second order texture features entropy and homogeneity, and the first order mean, median, kurtosis, and skewness) were extracted and compared structure-wise between patients with and without trismus. All MRI-derived features were calculated as the difference between T1pre and T1post, ΔS. Results: For 5/6 features and all structures, ΔS diverged between trismus and non-trismus patients particularly for the masseter, lateral pterygoid, and temporal muscles using the kurtosis feature (−0.2 vs. 6.4 for lateral pterygoid). Both the maximum and mean RT dose in all four muscles were higher amongst the trismus patients (with the maximum dose being up to 25 Gy higher). Conclusion: Using MRI-derived features to quantify RT-induced normal tissue complications is feasible. We showed that several features are different between patients with and without morbidity and that the RT dose in all investigated structures are higher amongst patients with morbidity. MRI-derived features, therefore, has the potential to improve predictions of normal tissue morbidity.« less

The aim of the present study was to compare the effects of daily single-dose use of flurbiprofen, diclofenac sodium, and tenoxicam on pain, swelling, and trismus that occur after surgical extraction of impacted wisdom teeth using local anesthesia. The present study included 3 groups with 30 patients in each group. Those volunteering to participate in this double-blind randomized study (n = 90) were selected from a patient population with an indication for extraction of impacted wisdom teeth. Group 1 patients received 200 mg flurbiprofen, group 2 patients received 100 mg diclofenac sodium, and group 3 patients received 20 mg tenoxicam. All doses were once a day, starting preoperatively. Pain was evaluated postoperatively at 1, 2, 3, 6, 8, and 24 hours and at 2 and 7 days using a visual analog scale (VAS). For comparison with the preoperative measurements, the patients were invited to postoperative follow-up visits 2 and 7 days after extraction to evaluate for swelling and trismus. The statistical analysis was performed using descriptive statistics in SAS, version 9.4 (SAS Institute, Cary, NC), software. Statistical analysis of the pain, swelling, and trismus data was performed using the Kruskal-Wallis, Dunn, and Wilcoxon-Mann-Whitney U tests. The statistical level of significance was accepted at P = .05 and power of 0.80. Clinically, tenoxicam showed better analgesic and anti-inflammatory efficacy compared with diclofenac sodium and, in particular, flurbiprofen. Although the VAS scores in the evaluation of pain showed statistically significant differences at 2 days, no statistically significant difference was found for swelling and trismus. Our study evaluated the analgesic and anti-inflammatory effects with a daily single dose of flurbiprofen, diclofenac sodium, and tenoxicam. Daily 20 mg tenoxicam can be accepted as an adequate and safe option for patients after a surgical procedure. Copyright © 2016 American Association of Oral and Maxillofacial Surgeons.

Third molar surgery is one of the most common surgical procedures performed in general dentistry. Post-operative variables such as pain, swelling and trismus are major concerns after impacted mandibular third molar surgery. Use of passive tube drain is supposed to help reduce these immediate post-operative sequelae. The current study was designed to compare the effect of tube drain on immediate post-operative sequelae following impacted mandibular third molar surgery. To compare the post-operative sequelae after surgical removal of impacted mandibular third molar surgery with or without tube drain. Thirty patients with bilateral impacted mandibular third molars were divided into two groups: Test (with tube drain) and control (without tube drain) group. In the test group, a tube drain was inserted through the releasing incision, and kept in place for three days. The control group was left without a tube drain. The post-operative variables like, pain, swelling, and trismus were calculated after 24 hours, 72 hours, 7 days, and 15 days in both the groups and analyzed statistically using chi-square and t-test analysis. The test group showed lesser swelling as compared to control group, with the swelling variable showing statistically significant difference at post-operative day 3 and 7 (p≤ 0.05) in both groups. There were no statistically significant differences in pain and trismus variables in both the groups. The use of tube drain helps to control swelling following impacted mandibular third molar surgery. However, it does not have much effect on pain or trismus.

Pain, swelling and trismus are undesirable effects of extraction of impacted mandibular third molars. The authors conducted a study to evaluate the effectiveness of the muscle relaxant cyclobenzaprine when used as a supplement to cryotherapeutic, antibiotic and steroidal anti-inflammatory treatment with the aim of reducing undesirable consequences after third-molar extraction. The authors conducted a prospective, randomized, double-masked, placebo-controlled clinical trial involving 50 participants aged 18 to 29 years randomly assigned to receive cyclobenzaprine or the placebo. The authors used a split-mouth design, so each participant acted as his or her own control. For each participant, the authors extracted one impacted mandibular third molar on each side of the mouth at different times. Participants received 10 milligrams of cyclobenzaprine or a placebo once per day the day before surgery, the day of surgery and the first day after surgery. The authors assessed the participants' postoperative pain by means of a visual analog scale at four, six, eight, 12, 24 and 48 hours. They measured the participants' swelling and maximal interincisor distance at 48 hours and seven days. The authors assessed both sides of each participant's mouth for differences in pain, swelling and trismus. They found no statistically significant differences between sides of the mouth regarding these three variables. The results of this trial indicate that the influence of cyclobenzaprine over pain, swelling and trismus does not justify prescribing additional medication for patients undergoing third-molar extraction. The muscle relaxant cyclobenzaprine was ineffective in reducing pain, swelling and trismus after third-molar extraction.

The aim of this study was to compare the clinical efficacies of naproxen sodium-codeine phosphate in combination, benzydamine hydrochloride, and diclofenac potassium for pain, edema, and trismus after lower third molar extraction. Ninety healthy volunteers in whom impacted third molar extraction was indicated were randomly distributed into 3 groups. One hour before the tooth-extraction process, patients were administered one of the following drugs: naproxen sodium, 550 mg, and codeine phosphate, 30 mg, in a tablet; diclofenac potassium, 50 mg, in a coated pill; or benzydamine hydrochloride, 50 mg, in a coated pill. Pain assessment was conducted via a visual analog scale; edema assessment, by measuring the distances between predetermined facial landmarks; and trismus assessment, by measuring interincisal distance. Regarding rescue analgesics (paracetamol, 500 mg), the number and time of use by patients were recorded. Naproxen sodium-codeine phosphate was more effective for pain, edema, and trismus than diclofenac potassium and benzydamine hydrochloride (P < .05). Benzydamine hydrochloride yielded similar clinical responses to diclofenac potassium (P > .05). No drug-related side effects were observed. Naproxen sodium-codeine phosphate constitutes the drug of choice after the extraction of a patient's impacted lower third molar. Benzydamine hydrochloride has similar efficacy to diclofenac potassium, and it can be used as a nonsteroidal anti-inflammatory analgesic drug.

Rett syndrome (RTT) is a congenital neurological disorder associated with mutations in the gene encoding MECP2 on the X chromosome. An 18-year-old woman (150 cm in height and 29 kg in weight) had been diagnosed with RTT and showed myotonic trismus, frequent attacks of apnea, mental retardation, spastic paraplegia, scoliosis, and microcephalus with micrognathia. She was scheduled to undergo laparoscopic fundoplication and gastrostomy under general anesthesia. Nasal bronchofiberscopic intubation (BFI) was planned because difficult airway due to trismus and micrognathia was expected. Referring to the bispectral index (BIS), anesthesia was induced with intermittent intravenous thiopental (total 125 mg), resulting in successful opening of the mouth by 1.5 of a finger width and establishment of manual ventilation. Following intravenous administration of rocuronium (20 mg), oral BFI was easily accomplished despite Cormack grade III. Anesthesia was satisfactorily maintained with inhalation of sevoflurane (1.0-1.5%) and continuous infusion of remifentanil (0.1-0.2 microg x kg(-1) x min(-1)) with the BIS value ranging from 30 to 50. She recovered smoothly from anesthesia using sugammadex (50 mg). However, she immediately demonstrated trismus and an attack of apnea with shivering, which were successfully resolved by warming the body and intravenous fentanyl (50 microg bolus and subsequent infusion at a rate of 10 microg x hr(-1)). The postoperative course was uneventful. Characteristically, RTT shows an extremely wide range of neurological symptoms. Therefore, it is of great importance to respond to each of those symptoms during the perioperative management of patients with RTT.

Patients after surgery and radiation/chemoradiation for treatment of head and neck cancer often suffer from oral complications. These problems may be caused by surgery and radiation. Patients complain, for example, of swallowing problems and limited mouth opening (trismus). The maximal interincisal mouth opening (MIO) was measured in patients treated with surgery and radiation/chemoradiation for head and neck cancer at the Department of Otorhinolaryngology at the University of Rostock. These patients also completed a 20-item questionnaire concerning nutritional, sensual, and speech disorders and pain. One hundred one patients (16 female and 85 male) returned the questionnaire and were included in the study. About 50% of the patients had a limited mouth opening (<36 mm); patients with oropharyngeal cancer had a significant higher risk for trismus (p = .024) than patients with other head and neck cancers, especially compared to patients with laryngeal cancer (p = .013). The questionnaire showed that especially patients with oral cancer report about problems with opening the mouth (73%), eating (65%), drinking (73%), xerostomia (92%), speech disorders (68%), and voice (62%). Patients with laryngeal cancer only reported about problems with xerostomia (62%), speech (83%), and voice (90%), similar to patients with pharyngeal cancer. About half of the patients who underwent primary treatment for oral and oropharyngeal cancer developed trismus and reported about problems with opening the mouth, eating, drinking, dry mouth, voice, and speech. Trismus has a negative impact on quality of life and should be a focus in the postoperative management of patients with oral and oropharyngeal cancer, and, if diagnosed, special treatment should be initialized.

Introduction Factors that contribute to swelling and trismus are complex, and they are originated by surgical trauma. The aim of the present study was to determine whether clinical and radiographic factors could predict the level of swelling and trismus after lower third molar surgery, through longitudinal approach. Methodology A prospective longitudinal trial was carried out. Forty-five patients of both genders with clinical and radiographic diagnosis of asymptomatic mandibular impacted third molar and with no intake of analgesic or anti-inflammatory drugs 12 h prior to surgery were recruited and evaluated in a 72 h follow-up period. A mixed repeated measures model and backward and restricted maximal likelihood methods were used to analyze the data. Results Male gender, body mass index (BMI), the relation to the lingual and buccal walls, and age were determinants for predicting postoperative swelling and for exerting a significant influence (P < 0.05). Conclusions This study suggests the association of male gender, the relation to lingual and buccal walls, BMI, and age with measurement of swelling. PMID:29849848

Radiotherapy alone or in combination with chemotherapy and/or surgery is a well-known radical treatment for head and neck cancer patients. Nevertheless acute side effects (such as moist desquamation, skin erythema, loss of taste, mucositis etc.) and in particular late toxicities (osteoradionecrosis, xerostomia, trismus, radiation caries etc.) are often debilitating and underestimated. A multidisciplinary group of head and neck cancer specialists from Italy met in Milan with the aim of reaching a consensus on a clinical definition and management of these toxicities. The Delphi Appropriateness method was used for this consensus and external experts evaluated the conclusions. The paper contains 20 clusters of statements about the clinical definition and management of stomatological issues that reached consensus, and offers a review of the literature about these topics. The review was split into two parts: the first part dealt with dental pathologies and osteo-radionecrosis (10 clusters of statements), whereas this second part deals with trismus and xerostomia (10 clusters of statements).

To evaluate the preventative effect of intravenous 4 mg of dexamethasone and 8 mg oral dexamethasone on post-operative pain, swelling and trismus after the surgical extraction of mandibular third molars. A randomized clinical trial comprised of 200 patients (control group I intravenous and experimental group II orally) with impacted lower third molars, average age 20.8 years with no local or systemic problems, with bilateral impacted lower third molars, were operated under local anesthesia. Group I was given 4 mg IV and group II was given 8 mg orally of dexamethasone 1 h before procedure. The choice of which side to operate first and the amount of concentration of medication to use was made randomly and double-blindly. Post-operative pain was evaluated using a visual analog scale (VAS) and the degree of swelling was evaluated through facial reference points' variation. The presence of trismus was analyzed through measurement of the interincisal distance (IID). These assessments were obtained before the operation and 24 h, 48 h and 7th POD. No significant difference was found in facial swelling and trismus between IV 4 mg injection and oral 8 mg consumption after lower third molar surgery (student t test P > 0.05). The visual analogue scale scores for pain assessment showed no significant difference between IV injection and oral route of dexamethasone (student t test P > 0.05). Patients can be administered 8 mg oral dexamethasone is as effective as 4 mg intra venous route without much difference in final outcome at any given point of time.

Introduction Third molar surgery is one of the most common surgical procedures performed in general dentistry. Post-operative variables such as pain, swelling and trismus are major concerns after impacted mandibular third molar surgery. Use of passive tube drain is supposed to help reduce these immediate post-operative sequelae. The current study was designed to compare the effect of tube drain on immediate post-operative sequelae following impacted mandibular third molar surgery. Aim To compare the post-operative sequelae after surgical removal of impacted mandibular third molar surgery with or without tube drain. Materials and Methods Thirty patients with bilateral impacted mandibular third molars were divided into two groups: Test (with tube drain) and control (without tube drain) group. In the test group, a tube drain was inserted through the releasing incision, and kept in place for three days. The control group was left without a tube drain. The post-operative variables like, pain, swelling, and trismus were calculated after 24 hours, 72 hours, 7 days, and 15 days in both the groups and analyzed statistically using chi-square and t-test analysis. Results The test group showed lesser swelling as compared to control group, with the swelling variable showing statistically significant difference at post-operative day 3 and 7 (p≤ 0.05) in both groups. There were no statistically significant differences in pain and trismus variables in both the groups. Conclusion The use of tube drain helps to control swelling following impacted mandibular third molar surgery. However, it does not have much effect on pain or trismus. PMID:28209003

The use of corticosteroids to reduce the post-operative sequelae of lower third molar surgery, namely pain, swelling and trismus, has been well studied by many researchers over the past 6 decades. This study reviewed the reported outcome of corticosteroids used in controlling the above sequalae after third molar surgery. A PubMed, Medline, EMBASE and Google search was undertaken of all controlled clinical trials on the effects of corticosteroids on pain, swelling and trismus after lower third molar surgery. The review was limited to studies published over the last 10 years (2006-2015). Of the 46 initially retrieved articles, 34 were finally included. Eleven studies compared the effect of 2 similar (but different dose) or different group of corticosteroids. Thirty-one studies reported the effects of corticosteroids on all sequale, 2 reported the outcome on swelling and trismus and another 1 on swelling and pain only. In 16 of the studies, corticosteroid use resulted in significant reductions in pain after third molar removal. Twenty-two out of 29 studies reported reduced swelling against negative control while 18 out of 25 studies reported improved mouth opening. Fourteen studies reported the benefit of corticosteroids on all 3 sequelae, with 71.4% resulted from the use of methylprednisolone. Although there are some conflicting effects, the results of this analysis shows in general the benefits derived from short-term use of corticosteroids in relation to pain, swelling and trismus following third molar surgical extraction, with no side effects observed.

The aim of this study was to compare the influence of triangular and envelope flaps on trismus, pain, and facial swelling after mandibular third molar surgery. Twenty healthy patients with bilateral, symmetrically impacted mandibular third molars were included in this double-blinded, prospective, cross-over, randomized study. The patients were operated with envelope flap on one side and triangular flap on the other side. Trismus was determined by measuring maximum interincisal opening, and facial swelling was evaluated using a tape measuring method. Pain was determined using visual analog scale (VAS) and recording the number of pain pills taken. The facial swelling measurements and VAS scores were lower in the envelope flap group compared to the triangular flap group. There was no significant difference between the two flap designs in operation time, maximum interincisal opening, and the number of analgesics taken. Envelope flap yields to less facial swelling and reduced VAS scores in comparison to triangular flap. There is no clinical difference in trismus between the two flap designs. Despite the higher VAS scores with triangular flap, no additional doses of analgesics were required in triangular flap.

We report a case of cerebral deep venous thrombosis that manifested clinically by a pseudobulbar syndrome with major trismus, abnormal movements and static cerebellar syndrome. To our knowledge, only three other cases of deep cerebral venous thrombosis associated with cerebellar or pseudobulbar syndrome have been published since 1985. The relatively good prognosis in our patient could be explained by the partially intact internal cerebral veins as well as use of early anticoagulant therapy. There was a spontaneous hyperdensity of the falx cerebri and the tentorium cerebelli on the brain CT scan, an aspect highly contributive to diagnosis. This hyperdensity of the falx cerebri was found in 19 out of 22 cases of deep venous thrombosis detailed in the literature.

A randomized, blind, controlled clinical study was conducted with a convenience sample of 24 patients to evaluate the effectiveness of an aluminum gallium arsenide (AlGaAs) infrared laser 808 nm after third molar extraction by the use of infrared thermography technique. Patients were divided into four groups: erupted third molars were extracted from the patients in Group I and Group II, and impacted third molars were extracted from the patients in Group III and Group IV. Group I and Group III received mock laser therapy in which the device was powered off, and Group II and Group IV were exposed to laser light. Postoperative clinical parameters related to the third molar extraction were evaluated; these parameters included pain, trismus and edema. Circulatory patterns were also evaluated by infrared thermography that exhibited local temperature coefficient at different postoperative periods. A slight improvement was observed for swelling, pain and trismus in patients who received laser irradiation, although the differences were not statistically significant (P>0.05). Laser therapy had a significant influence on the local circulation in the area near the temporomandibular joint, as determined by infrared thermography (P<0.05). Laser therapy was able to change the local circulation, although it did not significantly influence swelling, pain or trismus during the postoperative period.

This study compared the analgesic and anti-inflammatory efficacy, trismus control, and tolerability of the combination of lysine clonixinate and tramadol (LCT) versus tramadol (T) alone after surgical removal of impacted mandibular third molars. This study was a double-blind, randomized clinical trial, including two study groups of 20 patients each, who exhibited acute pain subsequent to surgical extraction of two mandibular third molars. Pain intensity was quantified over a 96-h period using a visual analogue scale and a 5-point verbal rating scale. Secondary indicators of analgesic and anti-inflammatory efficacy, trismus control, and tolerability were determined. Patients administered LCT exhibited better therapeutic effects that those administered T. Fifty percent of patients in the LCT group rated this therapy as 'excellent analgesia' compared with only 10% in the T group. The onset of the analgesic effect of LCT was significantly faster, without any therapeutic failures. There were no significant differences between the groups with regard to anti-inflammatory effect or trismus. The results of this study suggest that the postsurgical analgesic efficacy of LCT in combination (LC 125 mg + T 25 mg) is superior to that obtained with T alone, administered at the standard dose of 50 mg, for up to 96 h after the extraction of both impacted mandibular third molars.

This study was carried out to compare the efficacy of preoperative single bolus antibiotics with a 5 day- postoperative antibiotic regimen in reducing pain, swelling, and trismus, surgical site infection (SSI) and alveolar osteitis (AO) after third molar surgery. A randomised experiment was done involving eighty-four patients. The patients were divided into two groups consisting of 42 patients each. A preoperative group was given an oral bolus of 2g amoxycillin capsules and 1g metronidazole tablets one hour before extraction, while those in the postoperative group were given a five-day regimen oral 500mg amoxycillin capsules thrice daily and 400mg metronidazole tablets thrice daily. The occurrence of postoperative pain, swelling, trismus, SSI and AO were compared between the groups. Seventy-nine patients completed the study; 38 patients in the preoperative group and 41 patients in the postoperative group. There was no difference between the groups in respect of the inflammatory complications. The four cases of AO occurred in the preoperative group. Single bolus antibiotic prophylaxis should be adequate for most cases of third molar surgery as the degree of degree of postoperative pain, swelling and trismus was similar in both groups. The use of single bolus antibiotic prophylaxis would also help reduce the cost of treatment in developing countries as well as reduce the risk of development of resistant strains. However, a five-day postoperative antibiotic regimen is advised in patient with risk factors for AO.

Objective: The aim of the following study is to determine the effect of primary closure or dressing on post-operative morbidity after impacted lower third molar surgery. Materials and Methods: This was a randomized clinical study of 72 patients who had surgical extraction of impacted mandibular third molars. The subjects were divided into two groups of A and B. Group A had total closure (primary closure) and Group B had whitehead varnish dressing of the socket. Pain, swelling and trismus were evaluated pre-operatively using visual analogue scale, flexible tape measuring method and inter-incisal distance measurement with Vernier Callipers respectively as well as post-operatively on 1st, 2nd, 3rd, 5th and 7th day. Results: The study participants consisted of 27 males and 45 females in a ratio 1:1.7. With a mean age of 24.7 ± 4.9 years (range 19-33 years) for Group A and 25.5 ± 4.3 years (range 20-39 years) for Group B. Post-operative pain was not significantly affected by the closure techniques (P > 0.05). Dressing was found to significantly reduce the degree of swelling and trismus peaking on the 2nd day (P = 0.0207 and P = 0.010 respectively). Conclusion: The use of dressing was more effective than primary closure to reduce the degree of swelling and trismus though its effect on post-operative pain reduction was not significant.

Swelling, pain and trismus are acute reversible inflammatory complications of impacted mandibular third molar (M3) surgery. They contribute to the deterioration of quality of life and loss of several useful working hours. This study aimed to investigate whether the use of a surgical drain following M3 surgery can minimise these inflammatory complications. Eighty consecutive patients who gave consent were enrolled into the study. Patients were assigned into two groups (drain and no drain) by systematic sampling method which was modified to ensure matching of patients by age, sex and spatial relationship of the impacted mandibular third molar. The patients in the drain group (n=40) had a Foley's catheter drain inserted into the wound after the surgical procedure while the patients in the no drain group (n=40) had their wound closed without the use of drain. All patients had primary wound closure with 3.0 black silk sutures after the procedure. Demographic data, cheek dimension and maximal mouth opening were recorded before the procedure. Pain, swelling and trismus were evaluated in the two groups at 24 hours, 48 hours and 7th day after surgery. Post operative swelling and visual analogue scale score for pain were comparatively lesser in the drain group patients. The maximal interincisal distance was also more in the drain group patients. The findings from this study indicated that there is a significant benefit of using a surgical drain in minimising postoperative oedema, pain and trismus following surgical removal of impacted mandibular third molar.

The aim of this study is to evaluate the effectiveness of the low-level laser therapy (LLLT) in the control of pain, swelling, and trismus associated with surgical removal of impacted lower third molars. Thirty patients were randomized into two treatment groups, each with 15 patients-group test (LLLT) and a group control (no-LLLT)-and were told to avoid any analgesics 12 h before the procedure. In group test, the 980-nm diode-laser (G-Laser 25 Galbiati, Italy) was applied, using a 600-μm handpiece, intraorally (lingual and vestibular) at 1 cm from the involved area and extraoral at the insertion point of the masseter muscle immediately after surgery and at 24 h. The group control received only routine management. Parameters used for LLLT were: continuous mode, at 300 mW (0.3 W) for a total of 180 s (60 s × 3) (0.3 W × 180 s=54 J). Group test showed improvement in the interincisal opening and remarkable reduction of trismus, swelling and intensity of pain on the first and the seventh postoperative days. Although LLLT has been reported to prevent swelling and trismus following the removal of impacted third molars, some of these studies reported a positive laser effect while others did not. All references to the use of laser therapy in the postoperative management of third molar surgery employ different methodologies and, in some, explanations as to selection of their respective radiation parameters are not given. This study has demonstrated that LLLT, with these parameters, is useful for the reduction of postoperative discomfort after third-molar surgery.

The aim of this study was the comparision of postoperative outcomes in impacted mandibular third molars that were treated using either platelet-rich fibrin (PRF), a combination of PRF and piezosurgery, or conventional rotatory osteotomy. The study included 20 patients; 40 extractions of impacted mandibular third molars were performed. Patients were divided into two main groups. In group A (n = 20), traditional surgery was performed on one side (Group 1, n = 10); traditional surgery was performed, and PRF was administered to the extracted socket on the other side of same patient (Group 2, n = 10). In group B (n = 20), on one side, piezosurgery was used for osteotomy, and PRF was administered (Group 3, n = 10); on the other side of same patient, traditional surgery was performed (Group 4, n = 10). Parameters assessed at baseline for each patient included pain, the number of analgesics taken, trismus, and cheek swelling. These variables were also assessed on postoperative days 1, 2, 3, and 7. Statistical analysis revealed a significant reduction in postoperative pain (sum of 1(st), 2(nd), 3(rd) and 7(th) days) and trismus (on postoperative day 1) in group 2 (traditional surgery + PRF group), and in postoperative pain, the number of analgesics taken (sum of 1(st), 2(nd),3(rd) and 7(th) days) and trismus (on postoperative day 1) in group 3 (piezosurgery + PRF group) compared to groups 1 and 4 (traditional surgery groups), (p ≤ 0.05). However, swelling on postoperative days 1, 3, and 7 did not differ among the groups (p > 0.05). Only difference was on second day between groups 1-4 and 2-4 (p ≤ 0.05). The results of our study have shown that the use of PRF with traditional surgery and PRF combined with piezosurgery significantly reduced pain during the postoperative period. In addition, PRF in combination with piezosurgery significantly decreased the number of analgesics taken. Both operations also significantly decreased trismus 24 h after the surgery. As a result of this study, PRF and combination use of PRF and piezosurgery have positive effects in reducing postoperative outcomes after impacted third molar surgery.

A systematic review and meta-analysis was conducted to answer the clinical question "Does the piezoelectric surgical technique produce fewer postoperative sequelae after lower third molar surgery than conventional rotary instruments?" A systematic and electronic search of several databases with specific key words, a reference search, and a manual search were performed from respective dates of inception through November 2014. The inclusion criteria were clinical human studies, including randomized controlled trials (RCTs), controlled clinical trials (CCTs), and retrospective studies, with the aim of comparing the piezoelectric surgical osteotomy technique to the standard rotary instrument technique in lower third molar surgery. Postoperative sequelae (oedema, trismus, and pain), the total number of analgesics taken, and the duration of surgery were analyzed. A total of nine articles were included, six RCTs, two CCTs, and one retrospective study. Six studies had a low risk of bias and three had a moderate risk of bias. A statistically significant difference was found between piezoelectric surgery and conventional rotary instrument surgery for lower third molar extraction with regard to postoperative sequelae (oedema, trismus, and pain) and the total number of analgesics taken (P=0.0001, P=0.0001, P<0.00001, and P<0.0001, respectively). However, a statistically significant increased surgery time was required in the piezoelectric osteotomy group (P<0.00001). The results of the meta-analysis showed that piezoelectric surgery significantly reduced the occurrence of postoperative sequelae (oedema, trismus, and pain) and the total number of analgesics taken compared to the conventional rotary instrument technique in lower third molar surgery, but required a longer surgery time.

Background The main clinical application of electromyography is to detect abnormalities in muscle function, to assess muscle activity for purposes of recruitment, and in the biomechanics of movement. Objectives To analyze electromyography (EMG) findings for masticatory muscles during chewing following surgical extraction of lower third molars, and to determine any correlation between pain, inflammation, trismus, and the EMG data registered. Material and Methods This prospective study included 31 patients. Surface EMG was used to study masseter and temporalis muscle function before lower third molar extraction and 72 hours and seven days after surgery. Clinical variables, pain, inflammation, and trismus were registered before and after surgery. Results Studying the area and size of the masticatory muscles, higher values were found for temporalis than masseter muscles, regardless of the surgical side, which points to the greater involvement of the temporalis muscle in mastication. Comparing the side where surgery had been performed with the non-surgical side, a sharp and statistically significant reduction in amplitude and area were noted on the surgical side reflecting major functional affectation. One week after surgery, amplitude and area had almost returned to base-line values, indicating almost complete recovery. While pain decreased progressively after surgery, inflammation peaked at 72 hours, while mouth opening reached a minimum at this time, returning to normality within the week. Conclusions Surgical extraction of lower third molars produces changes to electromyography activity that are more evident during the first hours after surgery and closely related to the intensity of pain suffered and the patient’s inflammatory responses, although they are not related to mouth opening capacity. Key words:Third molar surgery, electromyography, pain, inflammation, trismus, masticatory muscles. PMID:29274163

Mandibular fractures are rare in children. Symptoms of these fractures include preauricular pain and swelling, trismus and pain when opening the mouth, and they are often preceded by a fall on the chin. If the diagnosis is missed they may have serious consequences for the growth and development of the jaw. A 3-year-old boy was referred with a swelling in his left cheek, fever and vomiting. Two days earlier he had fallen on his chin. At physical examination he had severe preauricular pain on palpation and a trismus. The patient was admitted because of suspicion of a viral parotitis and the threat of dehydration. After discharge, he went to the dentist for examination of a molar that was painful to the touch. The dentist performed an orthopantomogram and discovered a fracture of the left mandibular collum. Any child with trauma to the chin should be observed for symptoms of a mandibular fracture, and if it seems necessary non-invasive radiographic examination should be performed.

Pain, swelling and trismus are common complications associated with third molar surgery. These complications have been reported to have an adverse effect on the quality of life of patients undergoing third molar surgery. To review the different modalities of minimizing inflammatory complications in third molar surgery. A medline literature search was performed to identify articles on management of inflammatory complications in third molar surgery. Standard textbooks of Oral and Maxillofacial Surgery were also consulted and some local scientific publications on the subject were reviewed. Methods ranges from surgical closure techniques, use of drains, physical therapy and pharmacological means. Studies reviewed have shown that no single modality effectively minimizes postoperative pain, swelling and trismus without undesirable effects. Inflammatory complications after third molar surgery still remains an important factor in quality of life of patients at the early postoperative periods. Oral surgeons should be aware of the different modalities of alleviation of these complications to make postoperative recovery more comfortable for patients.

This study aims to evaluate the effectiveness of local hyaluronic acid (HA) administration to surgically remove impacted third molar sockets and measure pain, swelling, and trismus. The study included a total of 25 healthy patients aged 18-29 years with asymptomatic bilaterally impacted lower third molars. All cases have been performed under local anesthesia. In the study group, 0.8% HA (Gengigel®) was applied in the postextraction sockets of the right third molars and in the control group nothing was applied to the extraction sockets of the left third molars. Postoperative pain, trismus, and swelling were evaluated on the 1st, 3rd, and 7th postoperative days. No difference was determined between groups in facial swelling and maximum mouth opening. However, the amount of pain significantly reduced in HA groups according to visual analog scale (P = 0.001). The results of this study showed that HA can produce an analgesic action in postextraction sockets after surgical removal of impacted teeth and therefore it has a clinical benefit to reduce usage of nonsteroidal anti-inflammatory drugs after dentoalveolar surgery.

Our aim was to compare the use of a conventional rotary handpiece and a Piezosurgical unit for extraction of lower third molars. We studied 40 patients, who were allocated alternately to have the third molar removed with either the handpiece or the Piezosurgical unit. Pain, trismus, and oedema were evaluated at baseline and then postoperatively, together with paraesthesiae, on postoperative days 1, 3, 5, 7, and 15. Damage to surrounding tissue was checked on the same day whereas dry socket was evaluated from postoperative day 3 onwards. More patients complained of pain in the conventional group, they also required more analgesics, and they developed trismus more often than in the Piezosurgery group. There was also significantly more postoperative swelling in the conventional group. Patients were also evaluated using the subjective Postoperative Symptom Severity (PoSSe) scale. Our results suggest that apart from some inherent limitations with the Piezotome, it is a valuable alternative for extraction of third molars.

The aim of this prospective randomised study was to assess the effects of tube drainage on postoperative discomfort after the extraction of impacted mandibular third molars. We studied 40 patients (11 men and 29 women) 18 years or older (mean (SD) 21 (3), range 18-29) who required extraction of mandibular third molars. We used a randomised crossover design by which if a drain was inserted on one side, then the other side was managed without a drain on a later occasion. Pain, swelling, and mouth opening were evaluated after 48 h and 7 days postoperatively in both groups. Facial swelling (p=0.001), pain p=0.001), and trismus (p=0.001) were significantly less common in the drained group compared with those not drained. We conclude that the use a tube drain is of benefit in minimising postoperative swelling, pain, and trismus after extraction of mandibular third molars.

Our aim was to compare the effects of the surgical drain and kinesiotape applications on postoperative morbidity after mandibular third molar surgery in a split-mouth study design. A single-centre, split-mouth study was performed in 23 patients who needed surgical removal of bilateral mandibular third molars. Each patient was treated with a drain tube on one side of the mandible and Kinesio tape (KT) on the contralateral side. Swelling was significantly greater in the KT group than in the drain group throughout the study period. The groups did not differ significantly in the amount of trismus at any time point. The Visual Analogue Scale (VAS)-measured pain intensity was significantly lower in the drainage group. Patients with KT had greater postoperative discomfort than those with a drain tube. All patients were generally satisfied with their treatments. Although both treatments were useful, a surgical drain was significantly more effective at reducing swelling and pain intensity than Kinesio tape. The effects of both on trismus were similar.

We compared postoperative outcomes after the removal of 80 impacted mandibular third molars in 59 patients. In the control group, osteotomies were done with traditional burs (n=20). The second group had traditional osteotomies and platelet-rich fibrin (PRF) placed into the socket of the extracted tooth (n=20). The third group had piezosurgery (n=20), and the fourth had piezosurgery and PRF placed in the extraction socket (n=20). Baseline variables were assessed preoperatively and included pain, the number of analgesics taken, trismus, and swelling. These were also assessed on postoperative days 1, 2, 3, and 7. There was a significant reduction (p<0.05) in pain on days 1, 2, and 3, and in the number of analgesics taken on days 2 and 3 in both PRF groups. However, in the piezosurgery alone group this was the case only on day 3. There was no significant difference in swelling and trismus between the control and other groups.

Povidone iodine is used primarily as an antiseptic to decrease surgical site infection. Its hemostatic and antiedematous properties in oral surgery also have been investigated recently. A randomized controlled clinical trial was performed in 30 patients undergoing mandibular third molar removal in a split-mouth design. In the study group, a povidone iodine solution with a concentration of 0.5 mg/mL was used as the coolant and irrigant solution, whereas normal saline was used in the control group. Swelling (orotragus and mentotragus distances), trismus (maximum interincisal opening), and pain (visual analog scale score) were evaluated on postoperative days 2 and 7. In the study group, a significant decrease in swelling and trismus was observed at the 2 postoperative visits (P = .00) compared with the control group. The decrease of pain in the study group was not statistically significant at either postoperative visit (P > .05). More patients (63%) were subjectively satisfied with the side treated with povidone iodine. Povidone iodine irrigation is an inexpensive and safe method to lessen the postoperative sequelae of third molar surgery. Copyright © 2015. Published by Elsevier Inc.

Radiotherapy alone or in combination with chemotherapy and/or surgery is the typical treatment for head and neck cancer patients. Acute side effects (such as oral mucositis, dermatitis, salivary changes, taste alterations, etc.), and late toxicities in particular (such as osteo-radionecrosis, hypo-salivation and xerostomia, trismus, radiation caries etc.), are often debilitating. These effects tend to be underestimated and insufficiently addressed in the medical community. A multidisciplinary group of head and neck cancer specialists met in Milan with the aim of reaching a consensus on clinical definitions and management of these toxicities. The Delphi Appropriateness method was used for developing the consensus, and external experts evaluated the conclusions. This paper contains 10 clusters of statements about the clinical definitions and management of head and neck cancer treatment sequels (dental pathologies and osteo-radionecroses) that reached consensus, and offers a review of the literature about these topics. The review was split into two parts: the first part dealt with dental pathologies and osteo-radionecroses (10 clusters of statements), whereas this second part deals with trismus and xerostomia.

A penetrating injury by a foreign body is comparatively common in the oral and maxillofacial region. On the other hand, injury to the temporomandibular joint (TMJ) by a foreign object is very rare. The TMJ is an anatomically narrow space surrounded by hard bony processes. An unusual case of trauma with severe trismus caused by a foreign body that impaled the TMJ is reported. A 55-year-old man presented with a 5 × 1-cm laceration to the right cheek caused by a flying object propelled during the use of a lawn mower. The edge of the foreign body had a metallic wire, which became imbedded in the wound. His jaw opening was severely limited. Computed tomography revealed that the foreign body was 3 mm in diameter and was impaled on the articular capsule. The object was successfully removed, and the wound and interior of the TMJ were irrigated. Rehabilitation of mouth opening was started on postoperative day 3. On day 9, mouth opening had improved to 35 mm, and he was discharged. After 1 year, mouth opening was 45 mm with no sign of any TMJ disorders. © 2016 John Wiley & Sons A/S.

The purpose of this study was to test the effect of the surgical removal of impacted mandibular third molars using piezosurgery versus the conventional surgical technique on postoperative sequelae and bone healing. Material and Methods. This study was carried out as a randomized controlled clinical trial: split mouth design. Twenty patients with bilateral mandibular third molar mesioangular impaction class II position B indicated for surgical extraction were treated randomly using either the piezosurgery or the conventional bur technique on each site. Duration of the procedure, postoperative edema, trismus, pain, healing, and bone density and quantity were evaluated up to 6 months postoperatively. Results. Test and control sites were compared using paired t-test. There was statistical significance in reduction of pain and swelling in test sites, where the time of the procedure was statistically increased in test site. For bone quantity and quality, statistical difference was found where test site showed better results. Conclusion. Piezosurgery technique improves quality of patient's life in form of decrease of postoperative pain, trismus, and swelling. Furthermore, it enhances bone quality within the extraction socket and bone quantity along the distal aspect of the mandibular second molar. PMID:27597866

Abstract Impacted third molars are frequently encountered in clinical work. Surgical removal of impacted third molars is often required to prevent clinical symptoms. Traditional rotary cutting instruments are potentially injurious, and piezosurgery, as a new osteotomy technique, has been introduced in oral and maxillofacial surgery. No consistent conclusion has been reached regarding whether this new technique is associated with fewer or less severe postoperative sequelae after third molar extraction. The aim of this study was to compare piezosurgery with rotary osteotomy techniques, with regard to surgery time and the severity of postoperative sequelae, including pain, swelling, and trismus. We conducted a systematic literature search in the Cochrane Library, PubMed, Embase, and Google Scholar. The eligibility criteria of this study included the following: the patients were clearly diagnosed as having impacted mandibular third molars; the patients underwent piezosurgery osteotomy, and in the control group rotary osteotomy techniques, for removing impacted third molars; the outcomes of interest include surgery time, trismus, swelling or pain; the studies are randomized controlled trials. We used random-effects models to calculate the difference in the outcomes, and the corresponding 95% confidence interval. We calculated the weighted mean difference if the trials used the same measurement, and a standardized mean difference if otherwise. A total of seven studies met the eligibility criteria and were included in our analysis. Compared with rotary osteotomy, patients undergoing piezosurgery experienced longer surgery time (mean difference 4.13 minutes, 95% confidence interval 2.75–5.52, P < 0.0001). Patients receiving the piezoelectric technique had less swelling at postoperative days 1, 3, 5, and 7 (all Ps ≤0.023). Additionally, there was a trend of less postoperative pain and trismus in the piezosurgery groups. The number of included randomized controlled trials and the sample size of each trial were relatively small, double blinding was not possible, and cost analysis was unavailable due to a lack of data. Our meta-analysis indicates that although patients undergoing piezosurgery experienced longer surgery time, they had less postoperative swelling, indicating that piezosurgery is a promising alternative technique for extraction of impacted third molars.

This study aims to describe the types of musculoskeletal impairment in head and neck cancer survivors and to evaluate objective and subjective measures of musculoskeletal impairment and identify areas of need in future studies. This is a cross-sectional pilot study of 29 head and neck cancer patients who were treated with resection and reconstruction. Subjective measures of musculoskeletal impairment (Neck Disability Index, Shoulder Pain and Disability Index, Vanderbilt Head and Neck Symptom Survey, General Symptom Survey) were collected and compared to objective measures (Cervical Range of Motion Device, Inter-incisal Distance). Digital photography was used to assess the severity of postural abnormalities. Findings were summarized using descriptive statistical and graphical methods. The majority of patients in this cohort suffered from neck disability (69%). Thirty-five percent of patients had shoulder pain and disability. Cervical range of motion deficits were observed in all directions. Inter-incisal distance averaged 33.4 mm and inversely correlated with self-reported jaw and trismus symptoms. Digital photography identified shoulder misalignment in 93% of subjects, head tilt in 89% of subjects, and postural deviation in 68% of subjects. Musculoskeletal impairment is a significant side effect in head and neck cancer survivors that results in chronic neck pain, shoulder disability, trismus, and postural deficits. Tools to describe postural deficits are needed.

Introduction. Patients with head and neck cancer suffer from various impairments due to the primary illness, as well as secondary consequences of the oncological treatment. This systematic review describes the effects of radiotherapy and/or chemotherapy on the functions of the upper aerodigestive tract in patients with head and neck cancer. Methods. A systematic literature search was performed by two independent reviewers using the electronic databases PubMed and Embase. All dates up to May 2016 were included. Results. Of the 947 abstracts, sixty articles met the inclusion criteria and described one or more aspects of the sequelae of radiotherapy and/or chemotherapy. Forty studies described swallowing-related problems, 24 described voice-related problems, seven described trismus, and 25 studies described general quality of life. Only 14 articles reported that speech pathologists conducted the interventions, of which only six articles described in detail what the interventions involved. Conclusion. In general, voice quality improved following intervention, whereas quality of life, dysphagia, and oral intake deteriorated during and after treatment. However, as a consequence of the diversity in treatment protocols and patient characteristics, the conclusions of most studies cannot be easily generalised. Further research on the effects of oncological interventions on the upper aerodigestive tract is needed. PMID:27722170

Methamphetamine, a highly addictive sympathomimetic stimulant, is currently widely abused worldwide and has been associated with devastating effects on oral health, resulting in the term "meth mouth". However, "meth mouth" pathology is primarily based on case reports with a lack of systematic clinical evaluation. Therefore, we have conducted a systematic study to investigate (1) the pharmacological impact of methamphetamine on oral health with regard to saliva function, including the parameters saliva flow rate and total saliva production (ml/5 min) and the buffering capacity of saliva; (2) the contribution of the symptoms of bruxism and muscle trismus to potential oral health damage. We assessed the data of 100 chronic methamphetamine abusers and 100 matched-pair comparison participants. Primarily, we conducted an anamnesis with all methamphetamine abusers with regard to saliva dysfunctions, jaw clenching and pain in the temporomandibular joint. Subsequently, in the first part of the clinical enquiry, we tested the saliva flow rate and the total saliva production (ml/5 min) by using the sialometry method and the buffer capacity of saliva by determining the pH-value. In the second part of the clinical enquiry, we evaluated bruxism symptoms with respect to generalized tooth attrition, dentine exposure and visible enamel cracks and examined a potential muscle trismus by measuring the maximal opening of the mouth. The majority of methamphetamine abusers reported a dry mouth (72 %) and jaw clenching (68 %). Almost half of all methamphetamine abusers experienced pain in the temporomandibular joint (47 %). With regard to the clinical findings, methamphetamine abusers showed significantly lower total saliva production (ml/5 min) (p < 0.001), lower pH-values of their saliva (p < 0.001) and more bruxism symptoms (p < 0.001). However, we found no relevant trismus symptoms on comparing the two groups (p > 0.05). The sympathomimetic effects of chronic methamphetamine abuse may lead to dry mouth and extensive bruxism and therefore can increase the risk for caries decay, periodontal lesions and tooth wear. Furthermore, a significant decline of saliva buffer capacity in methamphetamine abusers may trigger the risk for dental erosions. Methamphetamine abusers and practitioners should be aware of these symptoms.

Data sourcesThe electronic databases searched included: PubMed/MEDLINE, Cochrane Central Register of Controlled Trials (Central) and Web of Science until June 2015. There was no restriction to language and the reference lists from relevant studies were searched for further articles.Study selectionRandomised and prospective controlled trials that compared the effect of submucosal injection of dexamethasone with that of placebo after impacted third molar surgery in humans. Studies involving volunteers with decompensated metabolic disease were excluded.Data extraction and synthesisStudy selection, data extraction and quality assessment (risk of bias) were assessed by two reviewers. All disagreements were resolved through discussion. A meta-analysis was performed for all continuous variables (oedema, pain and trismus) when at least two of the studies analysed the same data type.ResultsEight studies involving a total of 476 patients of which six were included in the meta-analysis. All of the surgical procedures were performed on the lower molars, submucosal injections of dexamethasone were used in concentrations of 4 mg, 8 mg, or 10 mg, and saline was used as a control. Antibiotic medications were administered prophylactically before surgery or by continuous use after the procedure. Seven of the eight studies identified the impactions according to the Pell and Gregory Classification. Oedema was measured using facial contours of pre-established reference points. The meta-analysis presented a mean difference (MD) of -2.20 (95% CI -2.70 to -1.70), with a statistically significant difference favouring dexamethasone (P< 0.00001). Trismus (assessed using inter-incisal distance upon maximum opening) had a MD of -2.92 (95% CI -7.13 to 1.29) and showed no statistically significant difference between groups. Pain was assessed using both visual analogue scales and number of analgesic taken; however, only studies including a VAS were used for meta-analysis. Pain presented with a MD of -1.79 (95% CI -3.28 to -0.30) and showed a statistically significant difference favouring dexamethasone.ConclusionsThe review found moderate quality evidence that submucosal injections of dexamethasone reduced post-operative oedema and pain compared to a placebo following impacted third molar surgery. There was no significant difference, in regards to trismus, between placebo and dexamethasone.

The purpose of the present study was to compare the effect of oral bromelain (4 × 250 mg) versus oral diclofenac sodium (4 × 25 mg) on pain, swelling, trismus, and quality of life (QOL) after surgical removal of impacted lower third molars. A randomized, double-blind, placebo-controlled study was planned. The sample included patients requiring extraction under local anesthesia of a single partial bony impacted mandibular third molar. The patients were randomly distributed into 1 of 3 groups: bromelain, diclofenac, and placebo. Treatment started 1 day before surgery and continued for 4 days. The predictor variable was the type of the drug given to the patients. The outcome variables were pain, swelling, and trismus, which were measured at 1, 3, and 7 days postoperatively. The other study variables included QOL measures to assess the patients' perception regarding the effect of surgery on their well-being and daily activities. A validated questionnaire was used to measure QOL. The data were analyzed using analysis of variance, multiple measures analysis of variance, or Pearson's χ(2) test, as appropriate. P < .05 was considered significant. A total of 45 subjects requiring surgical removal of a single impacted mandibular third molar under local anesthesia were included in the present study. The bromelain and diclofenac groups both showed a significant reduction in pain compared with the placebo group at all intervals (P < .05). Diclofenac also resulted in a significant reduction of swelling at 3 and 7 days, and bromelain resulted in an insignificant reduction. A nonsignificant reduction in trismus occurred in both treatment groups compared with the placebo group. Both treatment groups also showed a significant difference in the effect on QOL in most subscales and total scores (P < .05). The effect was comparable between the 2 treatment groups for all parameters and at all intervals. The results of our study have shown that oral bromelain is an effective therapy to improve the QOL after surgical removal of impacted lower third molars, with an effect on the postoperative sequelae comparable to that of preemptive diclofenac sodium.

Acute pericoronitis usually presents with severe localized pain, swelling and sometimes trismus. However, chronic pericoronitis and periodontal abscess produce a dull pain, moderate swelling and are occasionally seen migrating into distant sites producing fistulae intra-orally and/or extra-orally. This may quite often cause diagnostic dilemmas necessitating thorough medical and dental history, careful clinical examination and sometimes special investigations to confirm the etiology and or origin of infection. Here, we present three such cases and their management.

The aim of this study was to assess the feasibility of Er: YAG laser in bone cutting for removal of impacted lower third molar teeth and compare its outcomes with that of surgical bur. The study comprised 40 subjects requiring removal of impacted mandibular third molar, randomly categorized into two equal groups of 20 each, who had their impacted third molar removed either using Er: YAG laser or surgical bur as per their group, using standard methodology of extraction of impacted teeth. Clinical parameters like pain, bleeding, time taken for bone cutting, postoperative swelling, trismus, wound healing and complications were compared for both groups. Clinical parameters like pain, bleeding and swelling were lower in laser group than bur group, although the difference was statistically not significant. However, postoperative swelling showed significant difference in the two groups. Laser group required almost double the time taken for bone cutting with bur. Trismus persisted for a longer period in laser group. Wound healing and complications were assessed clinically and there was no significant difference in both the groups. Based on the results of our study, the possibility of bone cutting using lasers is pursued, the osteotomy is easily performed and the technique is better suited to minimally invasive surgical procedures. The use of Er: YAG laser may be considered as an alternative tool to surgical bur, specially in anxious patients.

This preliminary work documents the use of a powerful piezosurgery device to treat biphosphonate-related osteonecrosis of the jaw (BRONJ) in combination with classical medication therapy. Eight patients presenting 9 BRONJ sites were treated, 2 in the maxilla and 7 in the mandible. Reason for biphosphonate (BiP) intake was treatment of an oncologic disease for 5 patients and osteoporosis for 3. The oncologic and osteoporosis patients were diagnosed with BRONJ after 35-110 months and 80-183 months of BiP treatment, respectively. BRONJ 2 and 3 was found in 4 patients. Resection of the bone sequestrae was performed with a high power ultrasonic (piezo) surgery and antibiotics were administrated for 2 weeks. Soft tissue healing was incomplete at the 2-week control but it was achieved within 1 month. At the 1-year control, soft tissue healing was maintained at all patients, without symptom recurrence. One patient with paraesthesia had abated; of the 2 pa-tients with trismus, one was healed, severity of the second trismus abated. This case report series suggests that bone resection performed with a high power ultrasonic surgery device combined with antibiotics might lead to BRONJ healing. More patients are warranted to confirm the present findings and assess this treatment approach. PMID:24044030

The use of rigid fixation in children is controversial and may cause growth retardation along cranial suture lines. Intermaxillary fixation for mandibular fractures should be used cautiously as bony ankylosis in the temporomandibular joint (TMJ) and trismus may develop. The high osteogenic potential of the pediatric mandible allows non-surgical management to be successful in younger patients with conservative approaches. In this case, successful conservative treatment of mandibular fracture of a 3-year-old patient is presented.

This exploratory study examined novice intubators and the effect difficult airway factors have on pre- and posttraining oral-tracheal simulation intubation success rates. Using a two-level, full-factorial design of experimentation (DOE) involving a combination of six airway factors (curved vs. straight laryngoscope blade, trismus, tongue edema, laryngeal spasm, pharyngeal obstruction, or cervical immobilization), 64 airway scenarios were prospectively randomized to 12 critical care nurses to evaluate pre- and posttraining first-pass intubation success rates on a simulator. Scenario variables and intubation outcomes were analyzed using a generalized linear mixed-effects model to determine two-way main and interactive effects. Interactive effects between the six study factors were nonsignificant (p = 0.69). For both pre- and posttraining, main effects showed the straight blade (p = 0.006), tongue edema (p = 0.0001), and laryngeal spasm (p = 0.004) significantly reduced success rates, while trismus (p = 0.358), pharyngeal obstruction (p = 0.078), and cervical immobilization did not significantly change the success rate. First-pass intubation success rate on the simulator significantly improved (p = 0.005) from pre- (19%) to posttraining (36%). Design of experimentation is useful in analyzing the effect difficult airway factors and training have on simulator intubation success rates. Future quality improvement DOE simulator research studies should be performed to help clarify the relationship between simulator factors and patient intubation rates.

This case report presents an alternative method for fabricating an obturator for patients that develop xerostomia and mild trismus following radiation to the Head and Neck region. Multiple initial impression stages are avoided leading to less irritation to soft tissues and less discomfort to the patient. A 69-year-old male patient was referred to our dental practice by the Maxillofacial Surgery Department of the local General Hospital. The patient had undergone a right maxillectomy for removal of a Squamous Cell Carcinoma 2 weeks prior. Four endosseous dental implants were placed in the remaining upper jaw and 2 implants were inserted into the canine region of his edentulous mandible 3 weeks after ablative surgery. Five months following completion of radiotherapy and chemotherapy, a cone beam computed tomography of the maxilla was obtained, and a three dimensional model was constructed using an appropriate resin. Using the model as the detailed primary cast, a custom acrylic special tray was fabricated for the final impression of the remaining maxilla and the maxillary defect. An implant retained maxillary obturator and an implant retained mandibular overdenture were constructed to restore patient's speech, mastication and deglutition. The method presented here can limit the impression stages needed for construction of a maxillary obturator prosthesis to a single impression procedure advocating a partial digital workflow process. This can be very beneficial to the patient suffering from postradiation side-effects such as trismus, mucositis, and xerostomia.

Systematic review and meta-analysis of the efficacy of hilotherapy following oral and maxillofacial surgery.

Bates, A S; Knepil, G J

2016-01-01

Craniofacial surgery causes immediate postoperative pain, oedema, and functional limitations. Hilotherapy delivers cooled water to the face at 15°C and may reduce the postoperative recovery time. This work presents a meta-analysis of short-term postoperative outcomes after hilotherapy. Following a systematic literature search, comparative trials of patients undergoing surgical interventions in the maxillofacial region and receiving either hilotherapy or ice-cooling therapy were included for meta-analysis. Demographics and surgical outcomes were extracted. Data were analysed using Comprehensive Meta-Analysis software. Mean (SEM) data were calculated for demographic variables and standardized mean differences with the 95% confidence interval for surgical outcomes. Five trials were analysed, providing 206 patients for evaluation; mean patient age was 29.4 (9.4) years. Hilotherapy reduced pain (10-point visual analogue scale) at 48 h (P<0.010) and 72 h (P<0.050), as well as postoperative facial oedema (P<0.010), compared to ice-cooling treatment. Trismus and facial neurological scores were also improved (P=0.08). Patients preferred hilotherapy to other cooling methods (P<0.010). Hilotherapy appears to be effective in reducing postoperative facial pain, oedema, and trismus, and in improving patient-reported outcomes. Well-designed randomized controlled clinical trials are required to clarify the procedure-specific efficacy of postoperative hilotherapy and optimal durations of treatment.

Background The aim of this study was to assess the feasibility of Er: YAG laser in bone cutting for removal of impacted lower third molar teeth and compare its outcomes with that of surgical bur. Materials & methods The study comprised 40 subjects requiring removal of impacted mandibular third molar, randomly categorized into two equal groups of 20 each, who had their impacted third molar removed either using Er: YAG laser or surgical bur as per their group, using standard methodology of extraction of impacted teeth. Clinical parameters like pain, bleeding, time taken for bone cutting, postoperative swelling, trismus, wound healing and complications were compared for both groups. Observation & result Clinical parameters like pain, bleeding and swelling were lower in laser group than bur group, although the difference was statistically not significant. However, postoperative swelling showed significant difference in the two groups. Laser group required almost double the time taken for bone cutting with bur. Trismus persisted for a longer period in laser group. Wound healing and complications were assessed clinically and there was no significant difference in both the groups. Conclusion Based on the results of our study, the possibility of bone cutting using lasers is pursued, the osteotomy is easily performed and the technique is better suited to minimally invasive surgical procedures. The use of Er: YAG laser may be considered as an alternative tool to surgical bur, specially in anxious patients. PMID:25737885

We present a case report of a four-year-old boy with torcicollis and trismus after acute otitis media. Grisel Syndrome diagnosis in association with temporo-mandibular reactive arthritis was admitted, leading to early conservative treatment. GS should be suspected in a child presenting with torticollis after an upper respiratory tract infection or an ENT surgical procedure. The association with temporo-mandibular reactive findings is somehow rarer but not impossible, due to the close vascular communication between retropharyngeal and pterigoid spaces.

Effect of age, impaction types and operative time on inflammatory tissue reactions following lower third molar surgery

PubMed Central

2011-01-01

Background Postoperative mobidity following third molar surgery is affected by a number of factors. The study of these factors is essential for effective planning and limitation of morbidity. The aim of this study was to determine the effect of age, type of impaction and operative time on immediate postoperative tissue reactions following mandibular third molar surgery. Methods Consecutive patients with impacted mandibular third molar teeth were studied. All the third molars were classified according to Winter's classification. Surgical extraction was performed on all the patients by a single surgeon under local anaesthesia. The operation time was determined by the time lapse between incision and completion of suturing. Postoperative pain, swelling and trismus were evaluated. Results There were 120 patients with an age range of 19-42 years. Patients in the age range of 35-42 years recorded a lower pain score (p = 0.5) on day 1. The mouth opening was much better in the lower age group on day 2 and 5 (p = 0.007 and p = 0.01 respectively). Pain, swelling and trismus increased with increasing operative time. Distoangular impaction was significantly associated with higher VAS score on day 1 and 2 (p = 0.01, 0.0, 04). Distoangular and horizontal impaction are associated with a higher degree of swelling and reduced mouth opening on postoperative review days. Vertical impaction was associated with the least degree of facial swelling and best mouth opening. Conclusions Increasing operating time and advancing age are associated with more postoperative morbidity, likewise distoangular and horizontal impaction types. PMID:21527036

To compare the efficacy of preoperative submucosal injection of 4 mg of dexamethasone versus 40 mg of methylprednisolone in reducing postoperative sequelae after surgical removal of impacted mandibular third molars. This prospective, randomized, double-blind study included 65 patients who required surgical removal of impacted mandibular third molars with Class II or position B impaction (Pell and Gregory classification). Patients were randomly assigned to 1 of 3 groups: dexamethasone, methylprednisolone, or placebo (control). Surgery was performed with patients under local anesthesia. Baseline measurements were obtained preoperatively, and subsequent assessments were made on postoperative day 1, 2, 5, and 7 to measure postoperative facial swelling by use of 2 linear measurements: interincisal mouth opening width and visual analog scale score for pain. The amount of analgesics consumed was recorded. Wound healing also was assessed on postoperative day 7. Descriptive and multivariate statistics were computed, and significance was set at P < .05. Both methylprednisolone and dexamethasone significantly reduced swelling and trismus (P < .05, Kruskal-Wallis test), whereas the methylprednisolone group had significantly less pain (P < .05, Kruskal-Wallis test) and consumed a lower amount of analgesics (P < .05, χ 2 test) during the early postoperative days. The study findings suggest that a single preoperative dose of dexamethasone versus methylprednisolone was equally effective in reducing postoperative swelling and trismus. Pain control by these corticosteroids, however, was variable. Copyright © 2017 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc. All rights reserved.

The purpose of this case study is to present the findings of combining botulinum toxin type A (BoNT-A) and cervical spine manual therapy to address masseter muscle spasticity in a patient with Alzheimer-type dementia. A 78-year-old woman with bilateral spasticity of the masseteric regions for 2 years was referred for physiotherapy. She had trismus and bruxism, and could neither close nor open her mouth normally; thus, she was unable to be fed orally in a normal manner. The patient underwent combined treatment with BoNT-A and cervical spine manual therapy. A medical physician (neurologist) performed the BoNT-A injections into 2 points at the center of the lower third of the masseter muscle. A physical therapist performed manual therapy interventions targeted at the cervical spine. Manual therapy started the day after the BoNT-A injection and continued for 5 sessions per week for a total period of 2 weeks. Clinical outcomes were measured including spasticity (Modified Ashworth Scale), functionality (Barthel Index), and jaw opening. Outcomes were conducted at baseline, 2 weeks after treatment, and at 2-month follow-up session after finishing the treatment. The patient improved in all of the outcomes at the end of treatment, and these results were maintained during the follow-up. After treatment, the patient was able to feed with minimal caregiver dependency because oral feeding was possible. The patient in this study responded positively to a combination of BoNT-A and manual therapy, resulting in decreased masseter muscles spasticity and improved trismus and bruxism.

To compare outcomes of open reduction and internal fixation of displaced mandible fractures followed by either immediate mobilization or 2 weeks of mandibular-maxillary fixation. A prospective, randomized, single-blinded study was performed. The study was performed between January 1, 1997, and March 30, 2000. Inclusion criteria were displaced fractures between the mandibular angles, age greater than 16 years, and no involvement of the alveolus, ramus, condyles, or maxilla. All fractures were repaired by means of open reduction and internal fixation using 2.0-mm titanium plates secured either in transoral fashion or percutaneously. Data were collected at 6-week and 3- and 6-month postoperative examinations. Variables were assessed by a surgeon blinded to the history of immobilization and included pain, malunion or nonunion, occlusion, trismus, wound status, infection rates, dental hygiene, and weight loss. Twenty-nine consecutive patients were enrolled, 16 patients to immediate function and 13 patients to 2 weeks of mandibular-maxillary fixation. No statistically significant differences were found between groups for any of the variables. Immediate release and temporary immobilization showed mean weight loss of 10 and 8 pounds and trismus of 4.2 and 4.6 cm, respectively. One wound separation and one infection were seen in the immobilization population, and no wound separation or infection was seen in the immediate-release group. Dental hygiene was similar between the groups. No malunion or nonunion was noted in either group. In this prospective and randomized study, no significant differences were noted between the groups receiving either immediate release or 2 weeks of mandibular-maxillary fixation. The findings support the treatment of selective mandible fractures with 2.0-mm miniplates and immediate mobilization.

Introduction The incidence of tetanus has remained unacceptably high in developing countries. We aimed to describe the profile and outcome of children with tetanus admitted at the Lagos State University Teaching Hospital (LASUTH), Ikeja. Methods A prospective and cross-sectional study of children aged 1 month to 12 years of age admitted with clinical diagnosis of tetanus, between January 2011 and December 2013, at the Paediatric department of LASUTH. The age, sex, presenting complaint, immunization status, portal of entry, socio-economic class, complications, duration of admission and outcome of the subjects were analyzed using Microsoft Excel supplemented with Statistical Package for Social Sciences (SPSS) version 17.0. Level of significance set at p< 0.05. Results A total of 49 subject participated in the study. Male: Female ratio was 1.7: 1.0. mean age ± SD of 6.5± 3.2 years. Only 24.5% of the subjects were fully immunized, lower limb injury was the most common portal of entry (34.7%). Majority (79.6) were of the middle and lower social classes. Most of the subjects (67.3%) presented with generalised spasm. Only 1 patient (2.0%) did not have trismus. Case fatality rate was 4.1%. Conclusion Tetanus is still prevalent among children in our environment. It is commoner among those with no immunization or incomplete immunization, commoner in those in the middle and lower social class. Lower limb injury was the most common portal of entry. Trismus was a common presenting feature. There is a need to develop programmes with will help improve compliance to immunization. PMID:26526006

Postoperative pain, swelling and trismus are the most common outcome after third molar surgery. Many methods have been tried to improve postoperative comfort after surgery. Ketamine is a phencyclidine derivative that induces a state of dissociative anesthesia. It is a noncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist and has a distinct suppression effect on central nervous system (CNS) sensitization. Ketamine in a subanesthetic dose is set to produce analgesic and anti-inflammatory effect. Sixty patients, between the age group of 18 and 38 years, undergoing the extraction of impacted mandibular third molar, reporting to the department of oral and maxillofacial surgery were included in the study. Patients were divided randomly into two groups: local anesthetic alone (LAA) and local anesthetic and ketamine (LAK). Statistical analysis was performed using the Mann-Whitney U/unpaired--t-test and Wilcoxon signed-rank test. There was a significant difference in mouth opening in the LAA and LAK group in the immediate postoperative period. There was a significant difference between the two groups after 1 hour (LAA: 2.37; LAK: 1.40), and 4 hours (LAA: 2.37; LAK: 1.40). There was a significant difference in terms of facial swelling in the immediate postoperative period and day 1 between the LAA and LAK group. Use of subanesthetic dose of ketamine is not only safe but also valuable in reducing patient morbidity after third molar surgery. Combination of a local anesthetic and subanesthetic dose of ketamine during surgical extraction of third molars provides good postoperative analgesia with less swelling and significantly less trismus.

Third molar extraction is associated with considerable pain and discomfort, which is mostly managed with oral analgesic medication. We assessed the analgesic effect of benzydamine hydrochloride, a topical analgesic oral rinse, for controlling postoperative pain following third molar extraction. A randomized controlled trial was conducted in 40 patients divided into two groups, for extraction of fully erupted third molar. Groups A received benzydamine hydrochloride mouthwash and group B received normal saline gargle with oral ibuprofen and paracetamol. Oral ibuprofen and paracetamol was the rescue analgesic drug in group A. Patients were evaluated on the 3 rd and 7 th post-operative days (POD) for pain using the visual analogue score (VAS), trismus, total number of analgesics consumed, and satisfaction level of patients. The VAS in groups A and B on POD3 and POD7 was 4.55 ± 2.54 and 3.95 ± 1.8, and 1.2 ± 1.64 and 0.95 ± 1.14, respectively and was statistically insignificant. The number of analgesics consumed in groups A and B on POD3 (5.25 ± 2.22 and 6.05 ± 2.43) was not statistically different from that consumed on POD7 (9.15 ± 5.93 and 10.65 ± 6.46). The p values for trismus on POD3 and POD7 were 0.609 and 0.490, respectively and those for patient satisfaction level on POD3 and POD7 were 0.283 and 0.217, respectively. Benzydamine hydrochloride oral rinses do not significantly reduce intake of oral analgesics and are inadequate for pain relief following mandibular third molar extraction.

Masseter muscle hypertrophy is a rare condition of idiopathic cause. It clinically presents as an enlargement of one or both masseter muscles. Most patients complain of facial asymmetry; however, symptoms such as trismus, protrusion, and bruxism may also occur. Several treatment options reported for masseter hypertrophy are present, which range from simple pharmacotherapy to more invasive surgical reduction. Keloid scar with unilateral masseter hypertrophy is a rarely seen in clinical practice. This paper reports a case of unilateral masseter hypertrophy with keloid scar in the angle of the mandible for which surgical treatment was rendered to the patient by using a single approach.

Tiagabine May Reduce Bruxism and Associated Temporomandibular Joint Pain

PubMed Central

Kast, R. E.

2005-01-01

Tiagabine is an anticonvulsant gamma-aminobutyric acid reuptake inhibitor commonly used as an add-on treatment of refractory partial seizures in persons over 12 years old. Four of the 5 cases reported here indicate that tiagabine might also be remarkably effective in suppressing nocturnal bruxism, trismus, and consequent morning pain in the teeth, masticatory musculature, jaw, and temporomandibular joint areas. Tiagabine has a benign adverse-effect profile, is easily tolerated, and retains effectiveness over time. Bed partners of these patients report that grinding noises have stopped; therefore, the tiagabine effect is probably not simply antinociceptive. The doses used to suppress nocturnal bruxism at bedtime (4–8 mg) are lower than those used to treat seizures. PMID:16252740

Septic arthritis of the temporo-mandibular joint (TMJ) is a rare disease that has been reported infrequently. To the best of the authors' knowledge, only one case of bilateral TMJ septic arthritis has been reported. The contamination may result from direct extension of adjacent infection (dental or ENT), from hematogenous spread of blood-borne organisms or from direct inoculation. The most common presenting are trismus and pain, although swelling, tenderness and erythema have also been described. In addition, patients may develop fever, regional lymphadenopathy and malocclusion. Through a successively bilateral case of TMJ arthritis, without obvious portal of entry of the bacteria, we will analyze characteristics and treatment of this disease.

Pradhan, Raunak; Kulkarni, Deepak

2017-01-01

Introduction Fear of dental pain is one of the most common reasons for delaying dental treatment. Local Anaesthesia (LA) is the most commonly employed technique of achieving pain control in dentistry. Pterygomandibular Nerve Block (PNB), for achieving mandibular anaesthesia has been the traditional technique used and is associated with a few set of complications which include pain, nerve injury, trismus, and rarely facial nerve palsy, and sustained soft tissue anaesthesia. These complications have resulted in a rapid need for research on alternative local anaesthetic techniques. Aim This study was undertaken with the objective to determine pain, duration, profoundness and complications associated with administration of Intraligamentary Injection Technique (ILT). Materials and Methods This study was conducted on 194 patients (male=122, female=72) who reported for dental extractions in mandibular posteriors. The ILT was administered with ligajet intraligamentary jet injector using cartridge containing lignocaine hydrochloride 2% with adrenaline 1:80000 and a 30 gauge needle at buccal (mesiobuccal), lingual, mesial and distal aspect of the mandibular molars. The data was analyzed by using statistical computer software SPSS 11.0 (Statistical package for social sciences 11.O version of SPSS Inc.). Median was derived for Pain on Injection (PI) and Pain during Procedure (PP). Mean and standard deviation was derived for Duration of Anaesthesia (DA). Results Various advantages were seen such as, localized soft tissue anaesthesia, decreased PI (SD=0.83), and minimal PP (SD=0.94). The DA (SD=4.62) and mean value of 24.06 minutes. Conclusion This study is one of its kinds where intraligamentary injection has been used for extraction of mandibular molars. It was also successfully used in patients with exaggerated gag reflex and patients suffering from trismus due to oral submucous fibrosis. The intraligamentary injection technique can thus be used effectively to anaesthetize mandibular molars, as a primary technique for extraction of mandibular posterior teeth. PMID:28274058

A 15-year-old female spayed domestic long-haired cat was referred for trismus, hypersalivation, and bilateral ocular discharge. On examination, the cat showed pain on palpation of the left zygomatic arch, palpable crepitus of the frontal region, and limited retropulsion of both globes. A contrast-enhanced sinonasal computed tomographic study was performed, showing facial distortion and extensive osteolysis of the skull, extending beyond the confines of the sinonasal and paranasal cavities. Additionally, soft tissue and fluid accumulation were observed in the nasal cavities and paranasal sinuses. Postmortem biopsy samples acquired from the calvarium yielded a histologic diagnosis of sinonasal adenosquamous carcinoma, a rare and particularly aggressive neoplasm previously only reported in the esophagus of one cat. © 2015 American College of Veterinary Radiology.

To determine by treatment plan comparison differences in toxicity risk reduction for patients with head and neck squamous cell carcinoma (HNSCC) from proton therapy either used for complete treatment or sequential boost treatment only. For 45 HNSCC patients, intensity-modulated photon (IMXT) and proton (IMPT) treatment plans were created including a dose escalation via simultaneous integrated boost with a one-step adaptation strategy after 25 fractions for sequential boost treatment. Dose accumulation was performed for pure IMXT treatment, pure IMPT treatment and for a mixed modality treatment with IMXT for the elective target followed by a sequential boost with IMPT. Treatment plan evaluation was based on modern normal tissue complication probability (NTCP) models for mucositis, xerostomia, aspiration, dysphagia, larynx edema and trismus. Individual NTCP differences between IMXT and IMPT (∆NTCPIMXT-IMPT) as well as between IMXT and the mixed modality treatment (∆NTCPIMXT-Mix) were calculated. Target coverage was similar in all three scenarios. NTCP values could be reduced in all patients using IMPT treatment. However, ∆NTCPIMXT-Mix values were a factor 2-10 smaller than ∆NTCPIMXT-IMPT. Assuming a threshold of ≥ 10% NTCP reduction in xerostomia or dysphagia risk as criterion for patient assignment to IMPT, less than 15% of the patients would be selected for a proton boost, while about 50% would be assigned to pure IMPT treatment. For mucositis and trismus, ∆NTCP ≥ 10% occurred in six and four patients, respectively, with pure IMPT treatment, while no such difference was identified with the proton boost. The use of IMPT generally reduces the expected toxicity risk while maintaining good tumor coverage in the examined HNSCC patients. A mixed modality treatment using IMPT solely for a sequential boost reduces the risk by 10% only in rare cases. In contrast, pure IMPT treatment may be reasonable for about half of the examined patient cohort considering the toxicities xerostomia and dysphagia, if a feasible strategy for patient anatomy changes is implemented.

Septic Arthritis of the Temporomandibular Joint--Unusual Presentations.

Lohiya, Sapna; Dillon, Jasjit

2016-01-01

This report describes 2 patients whose septic arthritis of the temporomandibular joint (SATMJ) presented atypically, resulting in treatment delay and complications. A 49-year-old man developed left-side facial allodynia, which was first treated unsuccessfully as trigeminal neuralgia. On day 21, the patient sustained facial trauma from a fall and presented to the emergency department (ED). Maxillofacial contrast-enhanced computed tomographic (CT) scan was suggestive of parotiditis, SATMJ, or hemarthrosis. His condition did not improve with empiric antibiotic treatment. On day 30, contrast-enhanced magnetic resonance imaging (MRI) confirmed SATMJ. Incision and drainage yielded 6 mL of pus and produced clinical improvement. Cultures grew methicillin-resistant Staphylococcus aureus, which was treated with amoxicillin plus clavulanate and sulfamethoxazole plus trimethoprim for 30 days. On day 59, the patient still had slight preauricular pain and CT-proved TMJ osteoarthritic changes. A 56-year-old woman developed right-side facial pain after a crown procedure on her right mandibular second molar. Oral prednisone (and clindamycin) produced partial relief. Her primary physician suspected temporal arteritis, but its biopsy result on day 11 was normal. Gradually, the patient developed trismus and malocclusion refractory to various medicines. On day 49, she presented to the ED. A contrast-enhanced maxillofacial CT scan suggested SATMJ. Incision and drainage yielded 30 mL of pus and produced clinical improvement. During days 50 to 57, the patient received intravenous ampicillin plus sulbactam and metronidazole. However, preauricular tenderness and drainage from the surgical incision persisted. On day 55, CT scan showed a residual abscess. Secondary debridement yielded 5 mL of pus. Culture grew coagulase-negative S aureus. On day 141, the patient still had slight preauricular pain and TMJ osteoarthritic changes on MRI. In these cases, the SATMJ diagnosis was delayed owing to the mildness of local and systemic manifestations, the possibility of confounding conditions, and the rarity of SATMJ. Contrast-enhanced CT and MRI facilitated the diagnosis. Abscess drainage alleviated the symptoms. Postinfectious osteoarthritis developed possibly from treatment delay. SATMJ should be considered in all patients with enigmatic preauricular pain, trismus, or malocclusion. Copyright © 2016 American Association of Oral and Maxillofacial Surgeons.

Oral submucous fibrosis (OSMF) is a chronic inflammatory disease resulting in progressive juxtaepithelial fibrosis of the oral soft tissues and can cause increasing difficulty in mastication, swallowing, speaking, and mouth opening. The treatment of severe trismus requires a combination of surgical release and physiotherapy. Often physiotherapy alone can modify tissue remodeling in OSMF to increase oral opening. This article describes the fabrication and use of a new mouth-exercising device that helps the patient to squeeze/stretch the cheek mucosa to increase elasticity. The device can be used as a sole treatment modality or can be used in association with pharmacological and surgical treatment modalities for OSMF. Improvement in mouth opening was observed in four OSMF patients treated with a mouth-exercising device for 6 months as a sole treatment modality. © 2012 by the American College of Prosthodontists.

Payment deferred: strychnine poisoning in Nicaragua 65 years ago.

Ferguson, M B; Vance, M A

2000-01-01

In 1933 in Leon, Nicaragua, a 22-year-old woman died after an acute convulsive illness in which she experienced trismus, opisthotonos, and hyperpyrexia. Three years later her husband, Oliverio Castaneda, was convicted of her murder and that of 2 other people in the same city. We went to Nicaragua to investigate documents involved with that case and evaluate whether the verdict of murder by strychnine was substantiated by the data. We present the results of the investigation and provide information about the practice of medicine, pharmacy, and toxicology early in this century. The clinical picture in all 3 cases suggests strychnine poisoning. The clinical, toxicological, and circumstantial evidence is strong and implicates Castaneda as a murderer and strychnine as the weapon. We conclude that Oliverio Castaneda was the probable perpetrator of three 1933 strychnine murders in Leon and that he may have previously used strychnine to kill others in Nicaragua and neighboring countries.

Ten congenital triggers fingers have been treated on a 3 years old girl after correction of congenital bilateral club feet. Such a case, without any other congenital malformation seems to be unique in the French literature and only found twice in the English one. This child in spite of a normal growth and good psychomotor development, presents an unusual face, with a mouth a little bit too small, but her karyotype is normal. No trismus and no microstomia were found to enable this case to be classified in a specific syndrome. The right diagnosis may be a non evolutive arthrogryposis of the extremities. Dividing the ten proximal pulleys (A1) let 10 voluminous nodules pass through and allowed full range of motion in nine out of ten fingers. A remaining flexion deformity of the proximal interphalangeal joint needed an anterior arthrolysis, the final result was good.

The Use of an Alternative Extraoral Periapical Technique for Patients with Severe Gag Reflex

2016-01-01

Gag reflex is a physiologic mechanism that promotes contraction of the muscles of the tongue and pharyngeal walls. Different factors, including intraoral radiographic films and sensors, may trigger this reflex. Patients with severe gag reflex may not be able to tolerate the presence of intraoral radiographic films or sensors during root canal therapy (RCT). This factor may prevent an appropriate intraoral radiograph, which is important in RCT. Different approaches have been used to facilitate dental procedures in patients suffering from severe gag reflex. The use of an extraoral radiographic technique is an alternative method to obtain working length confirmation in patients with severe gag reflex. In this report of 2 cases, the use of an extraoral radiographic technique as an alternative approach during RCT in patients with severe gag reflex associated with phobic behavior and trismus was successfully demonstrated.

A 20 year-old female in her 32nd week of gestation presented to the Emergency Department with dysphonia and dysphagia associated to a recent recurrence of a periapical abscess. Her oral examination showed trismus, elevated tongue and neck swelling. A clinical diagnosis of Ludwig's angina was reached, and empirical antibiotic coverage was started. The decompression and drainage placement was performed successfully under local anesthesia without airway compromise. At the moment, no clear guidelines exist for the acute treatment of Ludwig's angina. Establishment of a secure airway has long been considered the gold standard, yet new literature suggests a more conservative management. Ascertaining an early diagnosis at the Emergency Department, and involvement of Anesthesia, Obstetrics, and, Ear, Nose and Throat specialist services is vital for materno-fetal wellbeing. Careful evaluation of the airway status in addition to prompt antimicrobial therapy with surgical decompression may represent a plausible alternative in pregnant patients.

Neonatal tetanus (NNT) remains among the leading causes of morbidity and mortality in Nigeria and a huge challenge in achieving the fourth goal of the Millennium Development Goals. We reviewed the morbidity and mortality pattern among neonates with NNT admitted to the District General Hospital in north-east Nigeria from 2006 to 2009. Half of the patients were from rural areas and were delivered at home by untrained traditional birth attendants with no prior antenatal health care. Razor blades and scissors were the instruments used to cut the cord in nonhygienic conditions. Spasticity, lack of sucking, trismus, fever, omphalitis, risus sardonicus and opisthotonus were the most common presenting signs and symptoms. Overall, mortality was 56%. Health education of mothers and traditional birth attendants, the promotion of hospital delivery and antenatal tetanus immunization of all pregnant women, particularly in rural areas, are recommended if NNT is to be prevented.

Impression making is not only important but is also the most significant step in the fabrication of any fixed or removable prosthesis. Proper impression making may be hindered by certain pathologic conditions. Reduced mouth opening is one of the common mechanical obstructions for proper orientation of the impression tray in the patient's mouth. In patients with trismus induced by submucous fibrosis, the procedure may be even more difficult to carry out because of reduced tissue resiliency and obliteration of vestibular spaces. Use of sectional trays offers one of the alternatives to overcome the problem of restricted mouth opening. Fabrication of customized impression trays according to the patient dentition improves the accuracy of impression making. The present case reports describe the fabrication of sectional custom trays designed for dentulous patients with chronic tobacco-induced submucous fibrosis.

Head and neck inflammatory pseudotumor: Case series and review of the literature.

Inflammatory pseudotumor (IP) is an uncommon idiopathic lesion that often imitates malignancy clinically and radiologically. Inflammatory pseudotumors have been found to occur in various sites but rarely in the head and neck. The histopathology, imaging, and treatment of three unique cases of head and neck inflammatory pseudotumors are described in this case series. Patients in Cases 1 and 2 presented with right level II neck mass and left parotid tail mass, respectively. The patient in Case 3 presented with otalgia, jaw pain and trismus, and a left parapharyngeal space mass. The tumors in Cases 1 and 3 significantly decreased in size with tapered courses of oral corticosteroids. The tumor in Case 2 was surgically excised without disease recurrence. Malignancy must be ruled out with incisional or excisional biopsy. Treatment includes surgical excision, oral corticosteroids, or both. The literature shows that radiotherapy and small-molecule inhibitors may be promising alternatives. © The Author(s) 2016.

2016-01-01

Leukemia is the most common neoplastic disease of the white blood cells which is important as a pediatric malignancy. Oral manifestations occur frequently in leukemic patients and may present as initial evidence of the disease or its relapse. The symptoms include gingival enlargement and bleeding, oral ulceration, petechia, mucosal pallor, noma, trismus and oral infections. Oral lesions arise in both acute and chronic forms of all types of leukemia. These oral manifestations either may be the result of direct infiltration of leukemic cells (primary) or secondary to underlying thrombocytopenia, neutropenia, or impaired granulocyte function. Despite the fact that leukemia has long been known to be associated with oral lesions, the available literature on this topic consists mostly of case reports, without data summarizing the main oral changes for each type of leukemia. Therefore, the present review aimed at describing oral manifestations of all leukemia types and their dental management. This might be useful in early diagnosis, improving patient outcomes.

2015-04-01

Myositis ossificans (MO) is a rare disease involving heterotopic ossification in the muscle or soft tissue. Myositis ossificans traumatica (MOT) disease presents as a calcification within the injured muscle, resulting from a single or repetitive injury. There are few reports of MOT in the masticatory muscles. The case of a patient with MOT in the medial pterygoid muscle caused by a complication related to the extraction of an erupted upper third molar is reported. The major symptom was severe trismus. Despite surgical treatment, the disease relapsed. MOT can lead to serious consequences for the patient. Its aetiopathogenesis needs to be better understood, so that the most appropriate treatment is established and relapses are minimized. This will improve the quality of life of these patients.

Bone removal is necessary for extracting the third molars that are erupted, partially erupted, and/or impacted in bone. Hence, it is necessary to choose a surgical method or instruments that conform to anatomic landmarks and are based on physiological principles. Many authors have reported injuries to the adjacent tooth, especially the distal part of periodontium after removal of second molar. Hence, the present study was undertaken to assess and compare the surgical and postsurgi-cal outcomes of third molar removal using piezoelectric surgery and rotary bur. A total of 30 healthy adult individuals who were in need of prophylactic removal of impacted man-dibular third molar tooth with ideal condition were included for the study. Individuals were divided randomly into study groups of 15 each, so that the difficulty of surgery will be the same in both the groups. Group I - piezoelectric osteotomy technique and group II - rotary osteotomy technique. The rotary device consists of a hand piece and a rotary speed ranging around 35,000 rpm was used. The piezoelectric device consists of a hand piece, and a frequency of 25 to 29 kHz with a microvibration of 60 to 200 mm/sec was used with a boosted working mode. Data were analyzed using unpaired t-test and qualitative data were analyzed using Fischer's exact test. The average age of the study subjects in the piezo-surgery group and rotary group was 28.40 ± 2.69 and 30.06 ± 3.15 years respectively. The time taken for removal of impacted tooth by rotary bur was less than that by piezoelectric device, which was significant statistically (p < 0.05). Until the 4th postoperative day, severity of pain experienced was more in the rotary group, which was statistically significant (p < 0.005). Mouth opening was significantly better in the piezoelectric group as compared with rotary bur until the 7th postoperative day. The piezosurgery method reduces postoperative pain, trismus, and swelling. Also, it may play an important role in increasing bone density within the extraction socket and decreasing the amount of bone loss of adjacent tooth in the distal aspect. In clinical practice, piezosurgery plays an important role because piezosurgery reduces postoperative pain, trismus, and also swelling.

Excision of Oral Submucous Fibrosis and Reconstruction with Full Thickness Skin Graft: A Case Study and Review of the Literature

Alshadwi, Ahmad; Bhatia, Ishwar

2012-01-01

Oral submucous fibrosis is a chronic debilitating disease characterized by gradually increasing fibrosis of the oral cavity and pharynx, mainly the buccal mucosa, resulting in trismus. The highest incidence of oral submucous fibrosis is seen in South India due to various deleterious habits. In spite of the numerous medical modalities employed in the management of oral submucous fibrosis, occasionally surgical intervention becomes inevitable. Various surgical approaches have been used to reconstruct the surgical defects following excision of fibrous bands. Full thickness skin grafts have been described in the literature with variable outcomes. In the present study a 38-year-old male presented with severe oral submucous fibrosis of the buccal mucosa, which was successfully treated and reconstructed using full thickness skin graft with stable functional result after one year of treatment. An integrated review of the literature regarding etiology, histopathology, diagnostic, and treatment modalities of the disease follows. PMID:23304568

Wound Healing Problems in the Mouth

2016-01-01

Wound healing is a primary survival mechanism that is largely taken for granted. The literature includes relatively little information about disturbed wound healing, and there is no acceptable classification describing wound healing process in the oral region. Wound healing comprises a sequence of complex biological processes. All tissues follow an essentially identical pattern to complete the healing process with minimal scar formation. The oral cavity is a remarkable environment in which wound healing occurs in warm oral fluid containing millions of microorganisms. The present review provides a basic overview of the wound healing process and with a discussion of the local and general factors that play roles in achieving efficient would healing. Results of oral cavity wound healing can vary from a clinically healed wound without scar formation and with histologically normal connective tissue under epithelial cells to extreme forms of trismus caused by fibrosis. Many local and general factors affect oral wound healing, and an improved understanding of these factors will help to address issues that lead to poor oral wound healing. PMID:27853435

Atypical mandibular metastasis as the first presentation of a colorectal cancer.

We describe a case of a 70-year-old man presenting with a mandibular metastasis as the first sign of a mucinous adenocarcinoma of the rectum. After 6 months of a protracted toothache, the patient presented with a palpable mandibular mass and trismus, precluding adequate clinical evaluation. A CT scan was performed, and imaging findings suggested an aggressive primary jawbone tumour, most likely an osteosarcoma. However, biopsy and further patient's management proved to be a metastasis. Metastasis to the oral cavity account for only 1%-3% of all malignant oral tumours, and the mandible is the most frequent site. Clinical presentation can be quite variable, and most often a primary malignancy is already known. Jawbone metastases are a sign of disseminated malignant neoplasms, with poor prognosis and usually an indication for palliative therapy. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

To evaluate the outcomes of patients with parapharyngeal space (PPS) tumors treated with a transoral robotic surgery (TORS) approach. We prospectively enrolled well-defined benign PPS tumors accessible from the oropharynx with no carotid encasement or bone erosion. We designated outcome measures that included technical feasibility of the approach, local tumor control and complication rates. Descriptive statistics were used to summarize the outcome data. With a mean follow-up of 29.9 months (range 12-40 months), a total of 10 patients have been enrolled. TORS was completed in 9 of 10 patients with acceptable operative time and blood loss and no significant complications including hemorrhage, infection, trismus or tumor spillage. Local control has been 100% for 7 patients with pleomorphic adenomas. We confirm the safety and feasibility of the TORS approach for PPS tumors that achieves a high local control and low surgical complication rate. TORS is a viable approach for removing benign tumors and lesions of the PPS. Copyright © 2010 S. Karger AG, Basel.

Tetanus can occur after an injury and is caused by the exotoxin of Clostridium tetani. Characteristics of generalised tetanus include spasms in the back and other muscles, trismus, risus sardonicus and difficulty in breathing caused by laryngospasms. Vaccination through the National Vaccination Programme of the Netherlands has resulted in 94% of the population being protected against tetanus; certain groups, however, have a low rate of vaccination. In the Netherlands, 5 patients were reported to have generalised tetanus in 2011. This figure is relatively high in comparison with previous years. Of these 5 patients, 3 did not receive post-exposure-prophylaxis (PEP) after their injuries, or received it incompletely. PEP may be comprised of 1 or more vaccinations with the tetanus toxoid and/or the administration of tetanus immunoglobulin. Patients who have sustained an injury should be evaluated in accordance with the guideline 'Tetanus' by the Landelijke Coördinatie Infectieziekten (National Coordination Centre for communicable disease control), and to assess whether PEP is indicated.

Methamphetamine abuse and “meth mouth” in Europe

Boyd, Geraldine-A.; Mancinelli, Luca; Pagano, Stefano; Eramo, Stefano

2015-01-01

With easy chemical synthesis from its precursor, methamphetamine (MA) is now widespread in many countries. The abuse of methamphetamine is associated with several negative effects on health, because MA is a neurotoxin and a dangerous central nervous system stimulant. It changes levels of neurotransmitters in the brain, releasing dopamine and inhibiting nor epinephrine uptake which increases sympathetic nervous system activity and can lead to cardiac arrhythmia, hypertension and tachypnea. The consequences of MA abuse are clearly manifested in oral diseases (like “meth mouth”) which is characterised by extensive caries, teeth grinding with ensuing dental wear and trismus. The present review was designed to fill the gap in knowledge about methamphetamine abuse in the European Union (EU) and to illustrate the main clinical effects of prolonged use. After describing the pharmacology and systemic effects of methamphetamine and concentrating on its effects on the mouth, the present review compares the epidemiology and incidence of abuse in the world, particularly the USA and the EU. Key words:Methamphetamine, “Meth mouth”, drug abuse, oral health. PMID:25662544

Tetanus is an acute, toxin-mediated disease caused by Clostridium tetani infection. Under favorable anaerobic conditions, such as in the unclean environment, necrotic wounds, this ubiquitous bacillus may produce tetanospasmin, an extremely potent neurotoxin. A 38-year-old man was admitted to an emergency room, at Zainoel Abidin General Hospital, with the main complaint of back-muscle stiffness. Based on physical examination, he was fully alert with a slightly rapid breathing, trismus with the maximum oral cavity opening was only about one finger width, but rhisus sardonicus was not evident. Ten days before admission, while gardening, his left foot accidentally stabbed by wooden tree stake. We immediately started a single dose of tetanus immunoglobulin followed by intravenous metronidazole, penicillin G, and intravenous diazepam. Tetanus diagnosed by physical clinical finding. The management of tetanus patients including the use of immunoglobulin and antibiotic therapy, analgesia, sedation and neuromuscular blockade management and mechanical ventilation, the care was delivered outside the Intensive care unit.

2006-04-01

A retrospective review of seventeen patients who were operated through the maxillary swing approach was carried out to assess the efficacy of this approach in the management of tumors of the central and lateral cranial base. From May 2000 to January 2005, 17 patients with primary or recurrent neoplasms involving the central cranial or lateral base underwent surgical resection via maxillary swing approach. Ten patients were male, and other seven patients were female, and age range was 7 to 58 years, with a mean age of 42. 6 years. Eight patients had tumors originally involving lateral cranial base, and nine patients had tumors originated from central cranial base. The pathology spectrum was very wide. Among them, five suffered from chordoma, two had rhabdomyosarcoma, two had squamous cell carcinoma, one had malignant fibrous histiocytoma, one had malignant melanoma, one had esthesioneuroblastoma, one had invaded hypophysoma, two had schwannoma, one had pleomorphic adenoma, and one had angiofibroma. Three patients had received previous surgery, two patients had previous radiation therapy and nine patients received postoperative radiotherapy. Sixteen of all seventeen patients had oncologically complete resection, one had near-total resection. This group patients was followed up from 10 to 60 months, with a median follow-up time of 28 months. Two patients died 14 and 26 months after surgery respectively, as a result of local recurrence and metastasis. One patient defaulted follow-up at 12 months after operation, and the other 14 patients were alive at the time of analysis. Of the 12 malignant tumors, the 1-and 2-year survival rate were 91.67% and 72.92%, respectively. The facial wounds of all patients healed primarily, and there were no necrosis of the maxilla, damage of the temporal branch of the facial nerve, lower-lid ectropion, and facial deformity. Epiphora and facial hypoesthesia were detected in all patients. Four patients (23.5%) developed palatal fistula, ten patients developed serous otitis media (58.8%), and four patients developed a certain degree of trismus (23.5%). Cerebrospinal fluid leak occurred in two patients. They subsequently healed with conservative management. The maxillary swing approach is a proven method for access to the central and lateral skull base with good exposure and acceptable morbidity. Complications and sequelae associated with this approach include facial scarring, transaction of the infraorbital nerve, impaired lacrimal drainage, eustachian tube dysfunction and serous otitis, palatal fistula, trismus etc. Some procedures should be performed for reducing the incidence and severity of complications in the maxillary swing approach.

Altered mental status, autonomic dysfunction, and neuromuscular abnormalities are a characteristic triad of serotonin syndrome. No laboratory tests confirm the diagnosis of serotonin syndrome. A 35-year-old woman took moclobemide, sertraline, and citalopram in a suicide attempt. She was conscious with mild tachycardia, hypertension, and tachypnea one hour after ingestion. In the second hour after ingestion diaphoresis, mydriasis, horizontal nystagmus, trismus, hyperreflexia, clonus, and tremor appeared. She became agitated and unresponsive. In the third hour after ingestion she became comatose and hyperthermic. She was anesthetized, paralyzed, intubated, and ventilated for 24 hours. Serum moclobemide, sertraline, and citalopram levels were above therapeutic levels. The serum serotonin level was within normal limits and the urinary 5-hydroxyindoleacetic acid:creatinine ratio was below the average daily value. The urinary serotonin:creatinine ratio was increased on arrival (1 mg/g). The urinary serotonin level is increased in serotonin syndrome due to a monoamine oxidase inhibitor and selective serotonin-reuptake inhibitors overdose. It is possible that urinary serotonin concentration could be used as a biochemical marker of serotonin syndrome.

Foreign body ingestion occurs in not only children but also adults, particularly those with history of neurologic disease, alcohol use, or psychiatric disease. We present the case of a 40-year-old male with schizophrenia who presented to the emergency room with a long history of pharyngeal foreign body sensation which had recently progressed to include trismus, odynophagia, and dyspnea. Flexible laryngoscopy demonstrated fullness of the right posterior pharyngeal wall and computed tomography (CT) showed a linear opaque foreign body extending from the level of the oropharynx to the thyroid ala. Further history elicited that he stabbed himself in the pharynx two years prior with a toothbrush following a command hallucination. The toothbrush was removed uneventfully via an external approach. The patient was discharged with psychiatry follow-up. This case is unusual due to the submucosal location of the foreign body and the length of retention. It demonstrates the atypical nature which patients with comorbid psychiatric illness may present following foreign body injury and the use of an external surgical approach for the removal of a retained foreign body based on CT reconstruction.

A 54-year-old woman diagnosed with multiple sclerosis (MS) at the age of 19 years was scheduled to undergo temporomandibular joint mobilization. She was currently in a remission phase from her MS but with persistent sequelae, including impaired eyesight and muscle weakness of the limbs. In addition, the blood vessels in her upper limbs were compromised by the formation of internal shunts secondary to vascular prosthesis replacements for plasma exchange therapy in MS. After a previous joint mobilization surgery, her temporomandibular joint developed adhesions with resultant trismus. One of the adverse effects of general anesthesia can be exacerbations of MS symptoms. Minimizing mental and physical stress caused by surgical and anesthetic procedures and maintenance of stable body temperature are important considerations. Awake intubation was performed under sedation with midazolam and fentanyl. After intubation, anesthesia was induced with propofol, remifentanil, and rocuronium. Maintenance of anesthesia was achieved with oxygen-N2O-sevoflurane, remifentanil, fentanyl, and rocuronium. In this case, no adverse events occurred intraoperatively. However, the patient experienced lingering weakness of the limbs in the postoperative period, and activities of daily living of the patient were affected. PMID:28604090

Oral submucous fibrosis (OSMF) is a well recognized premalignant condition predominantly affecting the oral cavity, but sometimes extending to the pharynx, esophagus or even the larynx. OSMF may lead to stiffness of the oral cavity, resulting in trismus and inability to eat, difficulty with speech or swallowing, pain in the throat and ears, and a relative loss of auditory acuity. To evaluate the hearing deficit in patients with OSMF, we examined a study group comprising 40 patients, and also 10 age- and sex-matched healthy subjects as controls. All of the subjects were evaluated for hearing loss by pure tone audiometry. The OSMF group showed a significant degree of hearing loss relative to the control group. OSMF in advanced stages was significantly associated with mild conductive hearing loss (P < 0.01). The present study revealed a significant association between OSMF and hearing deficit. Involvement of the palatal muscles with OSMF may decrease the patency of the Eustachian tube, leading to conductive hearing loss. Therefore, all patients with OSMF should be evaluated for hearing deficit and advised about appropriate treatment.

Rebamipide to Manage Stomatopyrosis in Oral Submucous Fibrosis.

Oral submucous fibrosis (OSF) causes progressive debilitating symptoms, such as oral burning sensation (stomatopyrosis) and limited mouth opening. The standard of care (SOC) protocol includes habit cessation, intralesional steroid and hyaluronidase injections, and mouth opening exercises. The objective of the study was to evaluate efficacy of rebamipide in alleviating burning sensation of the oral mucosa in OSF in comparison with SOC intralesional steroid injections. Twenty OSF patients were divided into two groups [rebamipide (100 mg TID for 21 days) and betamethasone (4 mg/mL biweekly for 4 weeks)] of 10 each by random sampling. Burning sensation was assessed every week for 1 month. Burning sensation scores were analyzed using repeated measures analysis of variance (ANOVA) and paired t-test. Change in burning sensation score was significant (p < 0.05) in the first four visits. However, score between the 4th and 5th visit was not statistically significant (p > 0.05). Our study has shown that rebamipide can be considered as an effective modality to manage burning sensation in patients suffering from OSF. Considering stomatopyrosis and trismus as a major cause for inability to eat in OSF, use of newer adjunctive modalities, such as rebamipide will ease patients suffering and also encourage them to consume food.

Biomechanical calculation of human TM joint loading with jaw opening.

2000-11-01

A three-dimensional, static mathematical calculation of the stomatognathic system was done to predict total temporomandibular joint (TMJ) loading at different levels of jaw opening. The model assumed that muscle forces acting on the mandible could be simulated by a combination of contractile components (CCs) and elastic components (ECs) and that static equilibrium existed within the body of the mandible. The model also imposed the constraint that any generated joint reaction force would act on the centre of the condyle. The results of the model demonstrated that under all conditions of opening and for all values of the elastic modulus selected, the forces between the TMJ condyle and the articular eminence were compressive in nature. The compressive force magnitude increased from 2.7 to 27.6 N incrementally as the jaw opened from 10 to 40 mm. Overall data in this study indicated that the TMJ tissues undergo low levels of compression at open positions up to 40 mm. Finally, the condition of trismus (increased jaw closing activation with opening) was simulated, the joint reaction force at 20 mm opening increased from 7.7 to 64.9 N with only a 20% activation of the closers.

Coming to America: betel nut and oral submucous fibrosis.

Aziz, Shahid R

2010-04-01

Oral submucous fibrosis (OSF) is an insidious precancerous disease affecting the oral cavity, pharynx and upper digestive tract. Its etiology is linked directly to betel nut use, which is common to the Indian subcontinent. With the increase in immigration of people from the Indian subcontinent to the United States, many American dental professionals will encounter this disease in the near future. The author provides a general overview of OSF. The author provides a literature review of OSF, including its epidemiology, etiology, clinical presentation, histopathology and treatment modalities. OSF is a precancerous oral disease linked definitively to the use of betel nut. It is endemic to people in the Indian subcontinent. Patients' primary complaint is progressive trismus. Treatment is based on disease severity. OSF is a debilitating but preventable oral disease. Its incidence in the United States will increase as the South Asian immigrant population expands. Consequently, American dental professionals may encounter patients with this disease, and it is important that they are aware of it. In addition, for dental care professionals practicing in a South Asian American community, public health education is important to inform the population about the deleterious oral health effects of betel nut consumption.

This study undertook a review of the literature on drug treatment of oral submucous fibrosis. An electronic search was carried out for articles published between January 1960 to November 2011. Studies with high level of evidence were included. The levels of evidence of the articles were classified after the guidelines of the Oxford Centre for Evidence-Based Medicine. The main outcome measures used were improvement in oral ulceration, burning sensation, blanching and trismus. Only 13 publications showed a high level of evidence (3 randomized controlled trials and 10 clinical trials/controlled clinical trials), with a total of 1157 patients. Drugs like steroids, hyaluronidase, human placenta extracts, chymotrypsin and collagenase, pentoxifylline, nylidrin hydrochloride, iron and multivitamin supplements including lycopene, have been used. Only systemic agents were associated with few adverse effects like gastritis, gastric irritation and peripheral flushing with pentoxifylline, and flushingly warm skin with nylidrin hydrochloride; all other side-effects were mild and mainly local. Few studies with high levels of evidence were found. The drug treatment that is currently available for oral submucous fibrosis is clearly inadequate. There is a need for high-quality randomized controlled trials with carefully selected and standardized outcome measures. Copyright © 2011 Elsevier Ltd. All rights reserved.

This study was a case record review of adult patients with tetanus admitted into Lagos University Teaching Hospital between 2000 and 2009. Of 78,009 adults admitted, 190 had tetanus, constituting 0.25% of admission. Mean age was 30.4 ± 13.8 years. Male to female ratio was 3:1. The commonest occupation was commercial motorcyclists. 96% of the patients were unimmunized and 4% that had partial immunization had localized tetanus. Commonest presentation was trismus (83%). Twenty three patients had complications, 30% had autonomic dysfunction. Mean incubation period was 11.4 ± 4.8 days, and mean duration of onset was 72 ± 45.6h. 31 patients died, case fatality rate was 16.3%. Twelve percent of those with long period of onset died while 43% with short period of onset died (P=0.002). Patients with complications (78%) died of tetanus while only 8% of those without complication died (P<0.0001). Case fatality rate is still unacceptably high for a vaccine preventable disease. Attention to primary prevention of people at risk and active surveillance to prevent complications will further reduce mortality. Copyright © 2012 Elsevier B.V. All rights reserved.

Tetanus is a very serious disease that can be fatal. Its incidence in the developed world has diminished considerably since the introduction of tetanus toxoid. More importantly, tetanus is one of the few infectious diseases that can be prevented. The recommendations for immunization are clear and readily available. In spite of the progress, we still see cases of tetanus in which the prognosis is poor. We present the case of a 67 year-old man that was admitted to our hospital with one of the most common manifestations of tetanus: trismus. Even though his treatment was established immediately, the hospital stay was long and made him susceptible to various medical complications and nosocomial infections. The incidence of tetanus in Puerto Rico is low but the mortality rate continues to be elevated in the high-risk group: patients older than 60 years of age. This is the reason for which we present this case. Our goal is to provide information with regards to epidemiology, pathogenesis, clinical manifestations, diagnosis and management of tetanus. In addition, it is equally essential to remind our colleagues the significance of adequate prevention of this potentially mortal and disabling disease.

The aim of this study was to review patients with tumours extending to the posterior portion of the upper gingiva and hard palate, and to evaluate the postoperative outcomes. Ten consecutive patients with tumours in the upper gingiva and hard palate, who underwent maxillectomy with internal dissection of the masticator space by the transmandibular approach, were reviewed retrospectively. Among the 10 patients, the pathological diagnosis was squamous cell carcinoma in seven, adenoid cystic carcinoma in one, malignant melanoma in one, and osteosarcoma in one. Loco-regional control was achieved in eight of nine patients (88.9%). Three patients had residual moderate trismus. Cosmetic issues were not noted in any patient. En bloc resection of the maxilla with the internal portion of the masticator space and neck through the parapharyngeal space by the transmandibular approach is a useful and satisfactory technique for the excision of a tumour with involvement of the posterior portion of the upper gingiva and hard palate.

Muscle activity contributes to the enhancement of facial aging deformity, blepharospasm, cerebral palsy spasticity, trismus, torticollis, and other conditions. Myotomy of the involved muscles in order to reduce the deformity has variable success rates due to muscle healing and regeneration of activity. The goal of this study was to investigate whether blocking striated muscle activity with Botulinum toxin (BtxA) during the healing time after myotomy alters the healing process and reduces long-term muscle activity. Eighteen Sprague Dawley rats where divided into 3 groups: group A (n = 7) underwent myotomy of their Latisimus Dorsi muscle; group B (n = 7) underwent myotomy and injection of BtxA into their severed muscle; group C (n = 4) injection of BtxA only. Muscle strength was tested periodically using a grip test. Starting at week 16 and until the termination of study at week 22, group B (Myotomy + BtxA) showed significant reduction in muscle power compared to the two control groups. Addition of BtxA injection into a muscle immediately after myotomy may interfere with muscle healing and contribute to a more successful long-term result.

Nonspeech Oral Movements and Oral Motor Disorders: A Narrative Review.

Kent, Ray D

2015-11-01

Speech and other oral functions such as swallowing have been compared and contrasted with oral behaviors variously labeled quasispeech, paraspeech, speechlike, and nonspeech, all of which overlap to some degree in neural control, muscles deployed, and movements performed. Efforts to understand the relationships among these behaviors are hindered by the lack of explicit and widely accepted definitions. This review article offers definitions and taxonomies for nonspeech oral movements and for diverse speaking tasks, both overt and covert. Review of the literature included searches of Medline, Google Scholar, HighWire Press, and various online sources. Search terms pertained to speech, quasispeech, paraspeech, speechlike, and nonspeech oral movements. Searches also were carried out for associated terms in oral biology, craniofacial physiology, and motor control. Nonspeech movements have a broad spectrum of clinical applications, including developmental speech and language disorders, motor speech disorders, feeding and swallowing difficulties, obstructive sleep apnea syndrome, trismus, and tardive stereotypies. The role and benefit of nonspeech oral movements are controversial in many oral motor disorders. It is argued that the clinical value of these movements can be elucidated through careful definitions and task descriptions such as those proposed in this review article.

Limited mouth opening in oral submucous fibrosis: reasons, ramifications, and remedies.

PubMed

Sharma, Mohit; Radhakrishnan, Raghu

2017-07-01

Limited mouth opening (LMO) in oral submucous fibrosis (OSF) has been attributed to both the submucosal and muscle fibrosis (MF). While reflectory trismus was proposed before as an auxiliary mechanism by another group, the stretch-mediated muscle damage (MSD), histopathological changes in blood vessels (such as endothelial dysfunction, endothelial hypertrophy, and endarteritis obliterans), and upregulated anaerobic isoforms of lactate dehydrogenase (LDH) have been proposed by us as complementary events leading to MF. Additionally, the amount of hypoxia-mediated upregulation of anaerobic isoforms of LDH determines the extent of MF. Radiotherapy (RT)-mediated release of reactive oxygen species causes vascular damage thereby worsening hypoxia. While the alteration in LDH levels secondary to hypoxia enhances fibrosis, RT worsens it. Oral squamous cell carcinoma occurring in the background of OSF is an absolute contraindication for RT as it augurs unfavorable prognosis. An algorithm to demonstrate this with evidence is clearly depicted. The role of HIF-1α in the progression of OSF and its malignant transformation, and the consideration of hyperbaric oxygen therapy as a therapeutic remedy in OSF are underscored. © 2016 John Wiley & Sons A/S.

Tracheostomy is a mainstay modality for airway management for patients with head-neck cancer undergoing surgery. This study aims to define factors predicting need of tracheostomy and define an effective objective criterion to predict tracheostomy need. 486 patients undergoing composite resections were studied. Factors analyzed were age, previous surgery, extent of surgery, trismus, extent of mandibular resection and reconstruction etc. Factors were divided into major and minor, using the clinical assessment scoring system for tracheostomy (CASST) criterion. Sixty seven (13.7%) patients required tracheostomy for their peri-operative management. Elective tracheostomies were done in 53 cases during surgery and post-operatively in 14 patients. All patients in whom tracheostomies were anticipated had a score of seven or more. A decision on whether or not an elective tracheotomy in head and neck surgery is necessary and can be facilitated using CASST criterion, which has a sensitivity of 95.5% and a negative predictive value (NPV) of 99.3%. It may reduce post-operative complications and contribute to safer treatment. Copyright © 2016 European Association for Cranio-Maxillo-Facial Surgery. Published by Elsevier Ltd. All rights reserved.

Effective treatments for patients with advanced locally recurrent nasopharyngeal carcinoma (NPC) are limited. This investigation was to determine the potential benefits from re-irradiation by intensity-modulated radiotherapy (IMRT) on survival and the effects of severe late toxicities. A retrospective study was conducted in 245 patients diagnosed with locally recurrent T3-T4 NPC who had undergone re-irradiation with IMRT. Follow-up data was colletedand factors associated with survival and severe late toxicities were analyzed. The 5-year local-regional failure-free survival, distant failure-free survival and overall survival rates were 60.9%, 78.3% and 27.5%, respectively. The presence of severe late complications, recurrent T4 disease and gross tumor volume >30 cm3 were associated with poor survival. The incidences of mucosal necrosis, temporal lobe necrosis, cranial neuropathy and trismus were 22.0%, 14.6%, 27.0% and 14.6% respectively. Re-irradiation with IMRT is an effective choice in patients with locally recurrent T3-T4 NPC. However, the survival benefits can be partly offset by severe late complications and optimum treatments in these patients remain a challenge.

The Prosthetic rehabilitation of microstomia patients presents difficulties at all the stages. The difficulty starts with the preliminary impression making. This is due to the tongue rigidity and the decreased oral opening. A maximum oral opening which is smaller than the size of the tray can make prosthetic treatment challenging. Due to the restricted mouth opening, insertion and removal of the impression trays is extremely cumbersome and various modifications of the trays have been used in the past. Among these are the flexible trays and the sectional trays used with different modes of reassembling the segments extra orally after the impression is made. This article reviews the literature published from 1971 to 2015 concerning preliminary impression techniques used in making impressions for patients with microstomia based on various tray designs. An electronic search was performed across three databases (PubMed, Science Direct and Google Scolar) for relevant citations. The keywords/combinations used for the search were microstomia, limited/constricted/restricted mouth opening/oral access, trismus, sectional trays, impressions and prosthetic/prosthodontic rehabilitation. The search was limited to papers written in English which resulted in a total of 45 related articles of which 17 articles were included for discussion of this review. PMID:27621540

Fibular osteoseptocutaneous flap has been widely used for unilateral mandibular reconstruction. However, reports about the effects of fibular osteoseptocutaneous flap for the reconstruction of bilateral mandibular defects are limited. In this study, we used free vascularized fibular flaps to successfully manage bilateral mandibular osteoradionecrosis(ORN) in 5 patients. Functional aspects were evaluated during the reconstruction process. All 5 patients had bilateral refractory ORN of the mandible and underwent radical resection between 2003 and 2011. The reconstruction surgery was performed in 2 stages using 2 free fibular flaps in 3 patients. In the other 2 patients, reconstruction was performed in a single stage using 2 separate flaps prepared from a single fibula. All patients had a healthy mandibular symphysis and meniscus of the temporomandibular joint, and these structures were preserved during the reconstruction.Of the 10 defects involving the mandible sides, 9 were successfully reconstructed. One microvascular composite flap failed because of radiation injury to the arterial endothelium at the recipient site. After the treatments, all patients had good esthetic and functional outcomes. Preoperative clinical features such as trismus and dysphagia were also markedly improved. Our surgical method may be an effective alternative for the clinical management of advanced bilateral mandibular ORN.

Juvenile nasopharyngeal angiofibroma often presents with lateral extensions. In countries with limited resources, selection of a cost-effective and least morbid surgical approach for complete excision is challenging. Sixty-three patients with juvenile nasopharyngeal angiofibroma, with lateral extensions, underwent transpalatal, transpalatal-circumaxillary (transpterygopalatine) or transpalatal-circumaxillary-sublabial approaches for resection. Clinico-radiological characteristics, tumour volume and intra-operative bleeding were recorded. The transpalatal approach was suitable for extensions involving medial part of pterygopalatine fossa; transpalatal-circumaxillary for extensions involving complete pterygopalatine fossa, with or without partial infratemporal fossa; and transpalatal-circumaxillary-sublabial for extensions involving complete infratemporal fossa, even cheek or temporal fossa up to zygomatic arch. Haemorrhage was greatest with the transpalatal-circumaxillary-sublabial approach, followed by transpalatal approach and transpalatal-circumaxillary approach (1212, 950 and 777 ml respectively). Tumour size (volume) was greatest with the transpalatal-circumaxillary approach, followed by transpalatal-circumaxillary-sublabial approach and transpalatal approach (40, 34 and 29 mm3). There was recurrence in three cases and residual disease in two cases. Long-term morbidity included small palatal perforation (n = 1), trismus (n = 1) and atrophic rhinitis (n = 2). These modified techniques, performed with endoscopic assistance under hypotensive anaesthesia, without embolisation, offer a superior option over other open procedures with regard to morbidity and recurrences.

OBJECTIVES: Access to the pterygopalatine fossa is very difficult due to its complex anatomy. Therefore, an open approach is traditionally used, but morbidity is unavoidable. To overcome this problem, an endoscopic endonasal approach was developed as a minimally invasive procedure. The surgical aim of the present study was to evaluate the utility of the endoscopic endonasal approach for the management of both benign and malignant tumors of the pterygopalatine fossa. METHOD: We report our experience with the endoscopic endonasal approach for the management of both benign and malignant tumors and summarize recent recommendations. A total of 13 patients underwent surgery via the endoscopic endonasal approach for pterygopalatine fossa masses from 2014 to 2016. This case group consisted of 12 benign tumors (10 juvenile nasopharyngeal angiofibromas and two schwannomas) and one malignant tumor. RESULTS: No recurrent tumor developed during the follow-up period. One residual tumor (juvenile nasopharyngeal angiofibroma) that remained in the cavernous sinus was stable. There were no significant complications. Typical sequelae included hypesthesia of the maxillary nerve, trismus, and dry eye syndrome. CONCLUSION: The low frequency of complications together with the high efficacy of resection support the use of the endoscopic endonasal approach as a feasible, safe, and beneficial technique for the management of masses in the pterygopalatine fossa.

Jaffe, N.; Toth, B.B.; Hoar, R.E.

1984-06-01

Sixty-eight long-term survivors of childhood cancer were evaluated for dental and maxillofacial abnormalities. Forty-five patients had received maxillofacial radiation for lymphoma, leukemia, rhabdomyosarcoma, and miscellaneous tumors. Forty-three of the 45 patients and the remaining 23 who had not received maxillofacial radiation also received chemotherapy. Dental and maxillofacial abnormalities were detected in 37 of the 45 (82%) radiated patients. Dental abnormalities comprised foreshortening and blunting of roots, incomplete calcification, premature closure of apices, delayed or arrested tooth development, and caries. Maxillofacial abnormalities comprised trismus, abnormal occlusal relationships, and facial deformities. The abnormalities were more severe in those patients who received radiationmore » at an earlier age and at higher dosages. Possible chemotherapeutic effects in five of 23 patients who received treatment for tumors located outside the head and neck region comprised acquired amelogenesis imperfecta, microdontia of bicuspid teeth, and a tendency toward thinning of roots with an enlarged pulp chamber. Dental and maxillofacial abnormalities should be recognized as a major consequence of maxillofacial radiation in long-term survivors of childhood cancer, and attempts to minimize or eliminate such sequelae should involve an effective interaction between radiation therapists, and medical and dental oncologists.« less

A case of tetanus infection in an adult with a protective tetanus antibody level.

Vollman, Kristan E; Acquisto, Nicole M; Bodkin, Ryan P

2014-04-01

Tetanus is a bacterial infection caused by Clostridium tetani and most commonly presents as trismus or other muscle spasms. Despite the development of the tetanus toxoid vaccine, tetanus infection has not been eradicated. Additionally, while there are hypothesized protective levels of tetanus antibody, tetanus infection may still occur in properly vaccinated individuals. We report the case of a 31-year-old male that presented to the emergency department (ED) with a 2-day history of neck and jaw pain. He reports puncturing his hand with a rusty nail 10 days prior. His reported vaccination history was that he received his last booster vaccination 13 years prior to presentation. In the ED, tetanus vaccine, tetanus immune globulin, and metronidazole were administered. His symptoms improved over the next 2 days and resolved at day 6. Despite his presentation of tetanus infection and rule out of other causes for his symptoms, his tetanus antibody level was reported at 8.4 U/mL, which is considered to be protective.A tetanus antibody level that is adequate for protective immunity should not preclude a patient from treatment of tetanus infection. This case demonstrates that a thorough history, physical exam, and rule out of other causes should guide treatment when there is concern for a tetanus infection.

The etiology of ectopic third molars located in the sigmoid notch of the mandible is unclear. Only a few cases have been reported. The aim of this article is to discuss the etiology as well as treatment options and diagnostic imaging techniques. A PubMed and Medline search of the literature from 1965 to 2015 to ectopic third molars in the mandibular notch was performed. Furthermore, a clinical case provided by the authors is reported. Among the eight reviewed cases, two male and six female patients were affected that ranged from 25 to 62 years of age (mean 48.4). Pain and swelling in the preauricular region or trismus but also the absence of symptoms was reported. Only in two of the summarized articles an extra-oral access for the removal of the tooth was used. The etiology seems to be individually different, however dentigerous cysts and chronic inflammation seem to play an important role in their appearance. While previous diagnostic reports described two-dimensional diagnostic imaging, currently the three-dimensional imaging is common for preoperative surgical planning with respect to removing ectopic molars. Ectopic third molars in the mandible are a rare condition. The etiology seems to be individually different. Nowadays, three-dimensional imaging is common for preoperative surgical planning.

Using a double-blinded randomized crossover design, this study aimed to evaluate acute postoperative pain management, swelling and trismus in 46 volunteers undergoing extractions of the two lower third molars, in similar positions, at two different appointments who consumed a tablet of either NE (naproxen 500 mg + esomepraz ole 20 mg) or only naproxen (500 mg) every 12 hours for 4 days. Parameters were analyzed: self-reported pain intensity using a visual analog scale (VAS) pre- and postoperative mouth opening; incidence, type and severity of adverse reactions; total quantity consumed of rescue medication; and pre- and postoperative swelling. Female volunteers reported significantly more postoperative pain at 1, 1.5, 2, 3 and 4hrs after surgery while also taking their first rescue medication at a time significantly earlier when consuming NE when compared to naproxen (3.7hrs and 6.7hrs). Conversely, no differences were found between each drug group in males. In conclusion, throughout the entire study, pain was mild after using either drug in both men and women with pain scores on average well below 40mm (VAS), although in women naproxen improved acute postoperative pain management when compared to NE.

Displacement of a Broken Dental Injection Needle Into the Perivertebral Space.

Dental injection needle breakage is an uncommon problem in dental practice. Displacement of the broken fragment into anatomical spaces is, on the other hand, a serious complication that occurs most commonly during inferior alveolar nerve blocks as a result of material wear, incorrect application of the anesthesia technique, or sudden movement of the patient during injection. Further complications such as infection, trismus, and nerve paralysis may exacerbate the condition and, if not treated adequately, life-threatening conditions may develop over time as the fragment dislodges deeper in soft tissues. Clinical symptoms of the patient, as well as the findings gathered from detailed physical examination and radiographic evaluation, are important factors to consider before performing an exploratory surgery. Removal of a broken needle may be troublesome due to its proximity to vital anatomic structures. Multislice computed tomography is a reliable imaging modality that provides accurate information to pinpoint the exact location of the needle fragment.This report describes a case of needle breakage occurred during inferior alveolar nerve block which was performed to extract a third molar tooth and the migration of the broken fragment from the right mandibular ramus area into the perivertebral space, with special emphasis on the surgical retrieval technique with multiplanar computed tomography imaging guidance.

This is the official guideline endorsed by the specialty associations involved in the care of head and neck cancer patients in the UK and provides recommendations on the pre-treatment oral and dental assessment, during and after treatment and oral rehabilitation. Restorative dentists are core members of the multidisciplinary team treating head and neck cancer patients, involved from the treatment planning phase through to long-term rehabilitation. Recommendations • Preventative oral care must be delivered to patients whose cancer treatment will affect the oral cavity, jaws, salivary glands and oral accessibility. (G) • Close working and communication between the surgeons, oncologists and restorative dental specialists is important in ensuring optimal oral health outcomes. (G) • Intensity-modulated radiotherapy has been shown to reduce long-term xerostomia and should be offered to all appropriate patients. (R) • If patients are deemed at risk of trismus they should be warned and its progressive and potentially irreversible nature explained. (G) • Where it is known that adjuvant radiotherapy will be given, extractions should take place at primary surgery to maximise the time for healing and minimise the number of surgical events for patients. (G) • Osseointegrated implants should be considered for all patients having resection for head and neck cancer. (G).

Describe the prevalence of communication, swallowing and orofacial myofunctional disorders in a group of children and adolescents at the time of registration at a cancer hospital. A cross-sectional study conducted with children aged ≥2 and adolescents, of both genders, admitted to the Pediatric Oncology Section of the Instituto Nacional de Câncer José de Alencar Gomes da Silva (INCA) from March 2014 to April 2015 for investigation and/or treatment of solid tumors. A protocol was used to record the sociodemographic and clinical information and findings of the speech-language pathology clinical evaluation, which included aspects of the oral sensorimotor system, swallowing, speech, language, voice, and hearing. Eighty-eight children/adolescents (41.3%) presented some type of speech-language disorder. The most frequent speech-language disorders were orofacial myofunctional disorder, dysphonia, and language impairments, whereas the less frequent ones were dysacusis, tongue paralysis, and trismus. Site of the lesion was the clinical variable that presented statistically significant correlation with presence of speech-language disorders. High prevalence of speech-language disorders was observed in children and adolescents at the time of admission at a cancer hospital. Occurrence of speech-language disorders was higher in participants with lesions in the central nervous system and in the head and neck region.

An epidermoid cyst is a benign cyst usually found on the skin. Bone cysts are very rare and if they appear in bone they usually appear in the distal phalanges of the fingers. Epidermoid cysts of the jaws are uncommon. We present a case, of a 41 year-old female patient admitted to our department because of pain and swelling in the parotid and masseteric region-left side. There was no trismus, pathological findings in skin, high body temperature level, infra-alveolar nerves anesthesia or lymphadenopathy present. The orthopantomography revealed a cystic lesion and a unilocular lesion that included mandibular ramus on the left side with 3 cm in diameter. Under total anesthesia, a cyst had been reached and was enucleated. Histopathologic findings showed that the pathologic lesion was an epidermoid cyst. Epidermoid and dermoid cysts are rare, benign lesions found throughout the body. Only a few cases in literature describe an intraossesus epidermoid cyst. Our case is an epidermoid cyst with a rare location in the region of the mandibular ramus. It is not associated with any trauma in this region except medical history reveals there was an operative removal of a wisdom tooth 12 years ago in the same side. These cysts are interesting from the etiological point of view. They should be considered in the differential diagnosis of other radiolucent lesions of the jaws. Surgically they have a very good prognosis, and are non-aggressive lesions.

To compare the effectiveness of two different routes of antibiotic administration in preventing septic complications in patients undergoing third molar extraction. Twenty-four healthy patients requiring bilateral surgical removal of impacted mandibular third molars were successfully enrolled for this study. Depth of impaction, angulation, and relationship of the lower third molars with the mandibular branch had to be overlapping on both sides. A split-mouth design was chosen, so each patient underwent both the first and second surgeries, having for each extraction a different antibiotic route of administration. The second extraction was carried out 1 month later. To compare the effects of the two routes of antibiotic administration, inflammatory parameters, such as edema, trismus, pain, fever, dysphagia and lymphadenopathy were evaluated 2 and 7 days after surgery. Side effects of each therapy were evaluated 48 h after surgery. Oral and intramuscular antibiotic therapies overlap in preventing post-operative complications in dental surgery (p>0.05), even if the oral intake, seems to promote the onset of significant gastrointestinal disorders (p=0.003). This study could help dentists in their ordinary practice to choose the right route of antibiotic administration in the third molar surgery. At the same effectiveness, the higher cost and the minor compliance of the patient seem not to justify a routine antibiotic intramuscular therapy, reserving it for patients with gastrointestinal disorders.

To determine clinical and pathological correlates of outcome among patients treated by surgery and postoperative radiation therapy for mucoepidermoid carcinoma of the parotid gland. Retrospective review. The medical records of 61 patients treated by surgery and postoperative radiation therapy for localized mucoepidermoid carcinoma of the parotid gland were retrospectively reviewed in an attempt to identify clinicopathologic correlates of overall survival. Secondary endpoints included local-regional control, distant metastasis-free survival, and complications. The 3- and 5-year estimates of overall survival were 85% and 79%, respectively. Multivariate analysis identified high tumor grade (hazard ratio [HR] = 7.92) and T4 disease (HR = 3.35) as independent predictors of decreased survival, with the former also predicting for distant metastasis and the latter predicting for local-regional recurrence. The 5-year estimate of overall survival was 83% for patients with non-high-grade tumors, compared to 52% for those with high-grade histology (P = 0.001). Late complications included trismus (2 patients), osteoradionecrosis (1 patient), and hearing loss (1 patient). Patients with high-grade tumors and T4 disease are at increased risk for treatment failure after surgery and postoperative radiation therapy for mucoepidermoid carcinoma of the parotid gland. Investigative strategies to improve outcome should be considered for these particular patients in the future. Copyright © 2013 The American Laryngological, Rhinological and Otological Society, Inc.

Peritonsillar abscess (PTA) is a very frequent reason for urgent outpatient consultation and otolaryngological hospital admission. Early, correct diagnosis and therapy of peritonsillar abscess are important to prevent possible life-threatening complications. Based on physical examinations, a reliable differentiation between peritonsillar cellulitis and peritonsillar abscess is restricted. A heterodimeric complex called calprotectin consists of the S100 proteins A8 and A9 (S100A8/A9) and is predominantly expressed not only in monocytes and neutrophils but also in epithelial cells. Due to its release by activated phagocytes at local sites of inflammation, we assumed S100A8/A9 to be a potential biomarker for peritonsillar abscess. We examined serum and saliva of patients with peritonsillitis, acute tonsillitis, peritonsillar abscess, and healthy controls and found significantly increased levels of S100A8/A9 in patients with PTA. Furthermore, we could identify halitosis, trismus, uvula edema, and unilateral swelling of the arched palate to be characteristic symptoms for PTA. Using a combination of these characteristic symptoms and S100A8/A9 levels, we developed a PTA score as an objective and appropriate tool to differentiate between peritonsillitis and peritonsillar abscess with a sensitivity of 92% and specificity of 93%.

We have evaluated the rationale of existing grading and staging schemes of oral submucous fibrosis (OSMF) based on how they are categorized. A novel classification and staging scheme is proposed. A total of 300 OSMF patients were evaluated for agreement between functional, clinical, and histopathological staging. Bilateral biopsies were assessed in 25 patients to evaluate for any differences in histopathological staging of OSMF in the same mouth. Extent of clinician agreement for categorized staging data was evaluated using Cohen's weighted kappa analysis. Cross-tabulation was performed on categorical grading data to understand the intercorrelation, and the unweighted kappa analysis was used to assess the bilateral grade agreement. Probabilities of less than 0.05 were considered significant. Data were analyzed using SPSS Statistics (version 25.0, IBM, USA). A low agreement was found between all the stages depicting the independent nature of trismus, clinical features, and histopathological components (K = 0.312, 0.167, 0.152) in OSMF. Following analysis, a three-component classification scheme (TFM classification) was developed that describes the severity of each independently, grouping them using a novel three-tier staging scheme as a guide to the treatment plan. The proposed classification and staging could be useful for effective communication, categorization, and for recording data and prognosis, and for guiding treatment plans. Furthermore, the classification considers OSMF malignant transformation in detail. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

To investigate the effect of antibiotics on postoperative inflammatory complications after surgical extraction of the impacted mandibular third molar. Ninety-Six patients had their bilateral third molars removed through a split-mouth, double-blind, controlled, clinical trial in two visits. On one side amoxicillin (or clindamycin) was used (antibiotics group) from 1 h pre-operation to 3 d post-operation. On the other side, placebo was used (placebo group) the same time. Postoperative inflammatory complications including alveolar osteitis (AO), surgical site infection (SSI), pre-buccal site infection and anterior isthmus faucium space infection were monitored and recorded 2 d and 10 d after the surgery. The pain, swelling, and trismus were also recorded. All 96 patients completed the study. Two AO (2.1%), one SSI (1.0%) and seven other infections were observed in the treatment group. Also three AO (3.1%), one SSI (1.0%) and eleven other infections were observed in the placebo group. However, no statistically significant differences were found in the incidence of various postoperative inflammatory complications and reactions between the groups (P > 0.05). There was no significant difference on the postoperative reaction, except pain on 10 d. Patients who had inflammatory infection recovered well with symptomatic anti-infection treatment. The use of amoxicillin (or clindamycin) cannot effectively prevent and reduce the postoperative inflammatory complications after surgical extraction of the impacted mandibular third molar.

The aim of this case-control study was to evaluate the postoperative period and healing between 2 surgical methods (traditional and ultrasound bone surgery) that are used for mandibular third-molar extraction. Fifteen patients with impaction of both of the lower third molars and indications for their extractions were used in this study. Bilateral-mandibular third-molar extractions were performed at the same surgical time: traditional surgery with burrs was used on 1 side (control site), and ultrasound surgery was used on the other side (test [T] site). After surgery, the patients were examined at 7 and 14 days and at 1 and 3 months to evaluate tissue healing. The following was assessed at every follow-up: pain, trismus, swelling, and alveolar bone level. The study included 15 patients, and 30 mandibular third-molar extractions were performed. We found only 1 postoperative complication: 1 patient had alveolitis in the control site. Complete recoveries without any complications were reported in all of the patients at the T sites. Complete recoveries without any complication were reported in all patients at the T sites. The only disadvantage of the piezoelectric technique was the length of operation time, which was increased by approximately 8 minutes; however, this effect was offset by reducing the morbidity. Our preliminary study showed that Piezosurgery is an excellent tool for reducing the risk of complications and improving the postoperative period.

The purpose of this meta-analysis was to evaluate the clinical efficacy of non-steroidal anti-inflammatory drugs and dexamethasone on the trismus, postsurgical pain, facial swelling, as well as the analgesic consumption after third molar surgery. The reports were identified in the most important medical databases. Those studies that met the requirements were fully assessed according to the inclusion and exclusion criteria. The quality of each report was evaluated with the Oxford Quality Scale and using the Cochrane Collaboration's risk of bias tool. Each meta-analysis was done using the technique of mean difference and 95% confidence intervals employing a random effects model with the Review Manager 5.3., from the Cochrane Library. Significant statistical difference was accepted when the p value was less than 0.05 on the test of overall effect (Z value). Qualitative evaluation was done using the data of 330 patients extracted from seven articles and the quantitative assessment with data of 200 patients from three reports. It was not observed difference among non-steroidal anti-inflammatory drugs and dexamethasone in any of the clinical effectiveness indicators. The outcomes of our meta-analysis indicate that non-steroidal anti-inflammatory drugs and dexamethasone have good therapeutic effect for the management of inflammatory complications following to third molar surgery. © Georg Thieme Verlag KG Stuttgart · New York.

2014-01-01

The likelihood of birth defects in orofacial tissues is high due to the structural and developmental complexity of the face and the susceptibility to intrinsic and extrinsic perturbations. Skeletal malocclusion is caused by the distortion of the proper mandibular and/or maxillary growth during fetal development. Patients with skeletal malocclusion may suffer from dental deformities, bruxism, teeth crowding, trismus, mastication difficulties, breathing obstruction and digestion disturbance if the problem is left untreated. In this review, we focused on skeletal malocclusion that affects 27.9% of the US population with different severity levels. We summarized the prevalence of class I, II and III of malocclusion in different ethnic groups and discussed the most frequent medical disorders associated with skeletal malocclusion. Dental anomalies that lead to malocclusion such as tooth agenesis, crowding, missing teeth and abnormal tooth size are not addressed in this review. We propose a modified version of malocclusion classification for research purposes to exhibit a clear distinction between skeletal vs. dental malocclusion in comparison to Angle’s classification. In addition, we performed a cross-sectional analysis on orthodontic (malocclusion) data through the BigMouth Dental Data Repository to calculate potential association between malocclusion with other medical conditions. In conclusion, this review emphasizes the need to identify genetic and environmental factors that cause or contribute risk to skeletal malocclusion and the possible association with other medical conditions to improve assessment, prognosis and therapeutic approaches.

Background Using a double-blinded randomized crossover design, this study aimed to evaluate acute postoperative pain management, swelling and trismus in 46 volunteers undergoing extractions of the two lower third molars, in similar positions, at two different appointments who consumed a tablet of either NE (naproxen 500 mg + esomepraz ole 20 mg) or only naproxen (500 mg) every 12 hours for 4 days. Material and Methods Parameters were analyzed: self-reported pain intensity using a visual analog scale (VAS) pre- and postoperative mouth opening; incidence, type and severity of adverse reactions; total quantity consumed of rescue medication; and pre- and postoperative swelling. Results Female volunteers reported significantly more postoperative pain at 1, 1.5, 2, 3 and 4hrs after surgery while also taking their first rescue medication at a time significantly earlier when consuming NE when compared to naproxen (3.7hrs and 6.7hrs). Conversely, no differences were found between each drug group in males. Conclusions In conclusion, throughout the entire study, pain was mild after using either drug in both men and women with pain scores on average well below 40mm (VAS), although in women naproxen improved acute postoperative pain management when compared to NE. Key words:Oral surgery, third molar, pain, naproxen, esomeprazole, NSAIDs. PMID:27918744

Aggarwal, Sushil Kumar; Ankur, Bhatnagar; Jain, R K

2015-09-01

We have described a new technique of using ultra-thin silicon sheet (0.2 mm) between two transected bony ends for temporo-mandibular joint (TMJ) ankylosis in children with advantages of short operative time, minimal foreign material insertion and faster recovery time post-operatively which makes our technique a good alternative to conventional techniques. Our study is a non-randomized prospective study conducted on 10 children aged between 4 and 15 years who presented to our tertiary care institute with severe trismus after traumatic injury and were willing to undergo this new technique. The main outcome measure taken into consideration was difference between pre-operative, intra-operative (on table) and post-operative mouth opening (minimum 2 years follow-up). The pre-operative mouth opening in our cases varied from 1 to 5 mm. The intra-operative mouth opening achieved ranged from 2.8 to 3.2 cm. The mouth opening was about more than 2.7 cm in all our cases at 2 years of follow-up. Our technique is a good alternative to conventional techniques used for TMJ ankylosis in children but few more randomized controlled trials are required to assess its effectiveness in comparison to conventional techniques and for universal adoption of this technique.

The aim of this study was to evaluate the use of a local anesthesia (LA) simulation model in a facilitated small group setting before dental students administered an inferior alveolar nerve block (IANB) for the first time. For this pilot study, 60 dental students transitioning from preclinical to clinical education were randomly assigned to either an experimental group (N=30) that participated in a small group session using the simulation model or a control group (N=30). After administering local anesthesia for the first time, students in both groups were given questionnaires regarding levels of preparedness and confidence when administering an IANB and level of anesthesia effectiveness and pain when receiving an IANB. Students in the experimental group exhibited a positive difference on all six questions regarding preparedness and confidence when administering LA to another student. One of these six questions ("I was prepared in administering local anesthesia for the first time") showed a statistically significant difference (p<0.05). Students who received LA from students who practiced on the simulation model also experienced fewer post-injection complications one day after receiving the IANB, including a statistically significant reduction in trismus. No statistically significant difference was found in level of effectiveness of the IANB or perceived levels of pain between the two groups. The results of this pilot study suggest that using a local anesthesia simulation model may be beneficial in increasing a dental student's level of comfort prior to administering local anesthesia for the first time.

Digital technologies related to imaging and manufacturing provide the clinician with a wide variety of treatment options. Stereolithography (SLA) offers a simple and predictable way for an accurate reconstruction of congenital or acquired defects. A 65-years old cancer patient with non- keratinized squamous cell carcinoma of left maxillary sinus came for a prosthetic clinical evaluation. A bilateral maxillectomy was performed and the treatment plan included definite obturator prosthesis for the upper arch. CT data and 3D planning software were used to create a 3D printing plastic model of the defect. A wax pattern of the hollow bulb was fabricated and cured with heat-cured silicone soft liner. A final impression was obtained with the hollow bulb placed intraorally. The master cast was duplicated and the new cast was invested and reflasked. The flasks were opened, wax was boiled out and some space was created in the internal part of the obturator. Transparent heat cured acrylic resin was sandwiched with, at the inner part of the bulb, improving the retention between the acrylic denture base and the silicone based soft lining material. The patient was then placed on a 6-month recall. The five-year follow up consists of a chair side relining, when needed, of the definite removable prostheses. Maxillofacial surgery patients may develop postoperative complications such as trismus and pain. In these cases, the combination of digital technology and conventional techniques provide an accurate prosthetic restoration.

The aims of this study were to demonstrate the surgical technique involved in the preauricular infratemporal fossa (ITF) approach, outline the clinical indications for use of this technique, and present the results in using this approach in 159 patients with malignant parotid tumors. At the conclusion of this article, the reader should be able to understand the utility of the preauricular infratemporal fossa approach in the management of patients with advanced malignant parotid tumors. This was a retrospective chart review of 159 patients treated at a tertiary care academic medical center following institutional review board approval. A comprehensive medical records review was performed for all patients with malignant parotid tumors who underwent a preauricular ITF approach between July 1988 and July 2010. The most common presenting symptoms were pain and trismus, whereas the presence of a parotid mass and facial paralysis were the most common clinical signs. Mucoepidermoid and adenoid cystic carcinoma accounted for 63% of the tumors, and perineural invasion was found in nearly 71% of the patients. Despite negative surgical margins in 92% of the patients, local or regional tumor recurrence was found in 17% of the cases. The mean follow-up time was 12.8 years. The preauricular ITF approach should be used in the surgical extirpation of advanced malignant parotid neoplasms. This technique provides proximal facial nerve identification, internal carotid artery protection, and negative tumor margins at the skull base.

To assess the influence of topical ozone administration on patient comfort after third molar surgery. A single-blinded randomized controlled clinical trial was designed involving patients who required removal of bilateral impacted mandibular third molars. The predictor variable was the postoperative medication used after third molar surgery. Using the split-mouth design, the study group received topical ozone without postoperative systemic antibiotics, whereas the control group did not receive ozone but only systemic antibiotics. The 2 groups were prescribed analgesics for 2 days. The assessing surgeon was blinded to treatment assignment. The primary outcome variables were postoperative mouth opening, pain, and swelling. The secondary outcome variable was the number of analgesic doses required by each group on postoperative days 3 to 5. Data analysis involved descriptive statistics, paired t tests, and 2-way analysis of variance with repeated measures (P < .05). SPSS 20.0 was used for data analysis. The study sample included 33 patients (n = 33 in each group). The study group showed statistically relevant decreases in postoperative pain, swelling, and trismus. Further, the number of analgesics required was smaller than in the control group. No adverse effects of ozone gel were observed in any patient. Ozone gel was found to be an effective topical agent that considerably improves patient comfort postoperatively and can be considered a substitute of postoperative systemic antibiotics.

Necrotizing fasciitis of the head and neck is a rare and potentially fatal disease. It is a bacterial infection characterized by spreading along fascia planes and subcutaneous tissue resulting in tissue necrosis and likely death. It is commonly of dental or pharyngeal origin. Factors affecting the success of the treatment are early diagnosis, appropriate antibiotics and surgical debridement. Our study showed eight patients, five males and three females with mean age of 49.25 years (range 20-71 years). Clinical presentations were a rapidly progressing painful neck swelling, fever, dysphagia and trismus. The aetiology varied from idiopathic, pharyngeal/tonsillar infection, trauma and nasal malignancy. There were associated variable comorbidities (diabetes mellitus, HIV infection, hypertension and congestive cardiac failure). All the patients received early and aggressive medical treatment. The earliest time of surgery was 12 h after admission because of the poor financial status of patients. Three cases came in with complications of the disease and were not fit for extensive debridement under general anaesthesia. For them limited and reasonable bed side debridement was done. Mortality was 50 % from multiple organ failure, HIV encephalopathy, aspiration pneumonitis and septicemia. The duration of hospital stay for the patients that died ranged from 1 to 16 days and 4 to 34 days for the survivor. Our study heightens awareness and outlines the management challenges of necrotizing fasciitis of the head and neck in a poor resource setting.

Incidence of lingual nerve paraesthesia following mandibular third molar surgery

PubMed Central

Lata, Jeevan; Tiwari, Arunesh K.

2011-01-01

Context: The surgical removal of impacted mandibular third molar is associated with minor but expected complications like pain, swelling, bruising and trismus. The lingual nerve damage sometimes occurs after the removal of mandibular third molar producing impaired sensation or permanent sensory loss. This complication is usually unexpected and unacceptable for the patients particularly if no prior warning has been given. Aims: The aim of the present clinical prospective study was to determine the clinical incidence of lingual nerve injury following mandibular third molar removal and to analyze possible factors for the lingual nerve injury. Settings and Design: Clinical prospective study in the Department of Oral Surgery, Punjab Government Dental College and Hospital, Amritsar. Materials and Methods: Ninety patients were selected randomly, amongst the patients, who reported to our department from January 2009 to December 2009 for the surgical removal of impacted mandibular third molar. To minimize the risk of lingual nerve injury, the standard terence wards incision was made in all cases and only buccal flap was raised. Statistical Analysis: The small number of paraesthesia precluded statistical analysis. Results: Out of 90 patients, six patients were diagnosed with lingual nerve paraesthesia. The overall incidence rate of lingual nerve injury was 6.6%. Conclusions: It can be concluded that lingual nerve paraesthesia can occur with or without reflection of lingual flap in spite of all the measures taken to protect it. It may be contributed to the fact of anatomical variations of lingual nerve. PMID:22639500

Head and neck squamous cell carcinoma (HNSCC) is an important public health problem in India. Several risk factors such as tobacco, human papilloma virus, alcohol, areca nut usage have been extensively studied as causative agents. Though Areca nut chewing is known cause of oral cancer, its association with hypopharynx cancer has not been previously reported. Since areca nut is mostly consumed along with tobacco, it is uncommon to find patients who consume the areca nut alone. This is a prospective case series of ten women who presented to us with HNSCC with history of chewing of areca nut alone for several years. We have excluded all those cases where areca nut was consumed along with tobacco in any form. The data were prospectively collected with regard to clinical parameters, duration and frequency of areca nut usage, the socio-economic status and education level. All ten females had varying degree of submucous fibrosis and coexisting squamous cell carcinoma either in the oral cavity or hypopharynx. Submucous fibrosis was characterized by burning mouth, unhealthy oral mucosa, buried third molars, trismus, poor oral hygiene, etc. The disease presented in an advanced stage in majority of the cases. All patients were unaware of areca nut's deleterious effects. Areca nut chewing is an important risk factor for HNSCC in females. Despite plethora of information, little importance is given to areca nut control in cancer prevention campaigns in India.

Bruxism, as an etiological factor for the development of TMD, includes different disorders of the TMJ and the masticatory muscles, exhibiting pain and disruption of the stomatognathic functions. Our goal was to study patients with bruxism and TMD from everyday dental clinical practice, in terms of diagnosis, identification of etiological factors, classification and treatment of these disorders. We treated 120 patients, divided into 2 groups of 60 patients. The first group had disorders of the TMJ, and the second of the masticatory muscles. The groups were divided into subgroups of 20 patients with dislocation of the articular disk with or without reduction and inflammation of TMJ. The second group was organized from patients with myofascial pain, myositis and muscular trismus. Our conservative treatment consisted of patient education, NSAID, myorelaxants, fabrication of prosthetics, repositioning and stabilization splints. The progress of the patients was followed immediately after the delivery of the prosthetics and the splint, after 1, 6 and 12 months. The results showed that in patients with disorders of the TMJ there were visible signs of recovery after 6 months in 68.3% patients, and in 85% after 12 months. In the second group we achieved faster results with the elimination of symptoms. Patients with afflictions of the muscles in 88.3% of cases noticed relief of symptoms even after 6 months and in 98.3% after 12 months. As therapists we concluded that timely treated complications of bruxism and TMD prevent the destruction of the TMJ, masticatory muscles and the entire stomatognatic system.

The aim of this study was to describe the epidemiological, clinical, and prognostic aspects of tetanus associated with road accidents and to make recommendations. This observational study collected retrospective clinical data over a 9-year period about adults admitted for trismus and/or generalized or localized paroxysm after a road accident. The study included 25 patients, accounting for 22.12 % of all tetanus cases. Men were massively overrepresented (sex-ratio M/F: 24/1). The median age was 34 ± 8 years. In all, vaccination status was unknown for 4 patients and known to be negative for 21. Immunoprophylaxis was nonexistent in all cases. The generalized clinical form was dominant (96 %). Severity reached level III for 12 % of patients. The points of entry included open leg fractures (4 cases), head wounds (2), mucocutaneous wounds (14), and muscle contusions (5). The mean time to referral for tetanus was 8 ± 7 days, and the median hospital stay 9.08 ± 11 days. Patients were mostly residents of urban (56 %) and suburban areas (28 %) [P = 0.04]. Two cases were complicated by severe malaria. The mortality rate was 60 %, and 52 % of the deaths occurred within the first 72 hours after hospitalization. It is essential to promote serum therapy and tetanus immunization for patients after road accidents. Increasing the awareness of traditional healers of these treatments deserves consideration.

The aim of the study was to provide an accurate account of current practice of laryngeal mask airway (LMA) use within SA Ambulance Service (SAAS) and identify issues that could lead to constructive training for paramedics and improve clinical care and patient safety. A clinical audit of LMA use within SAAS was registered with the Director of Clinical Governance at Flinders Medical Centre in South Australia. Data were collected prospectively in a state wide all inclusive study over 12 months (February 2006 to January 2007). The primary outcome variable we determined was successful insertion after one or two attempts. Secondary outcome measures were overall success rate and reasons for failure. Insertion of an LMA was attempted by 179 paramedical staff in 164 patients. Success after one or two attempts was obtained in 65% of patients (107/164). Overall success rate (any number of attempts) was 74% (121/164), of those 45% were on the first attempt, 20% on the second attempt and the remainder (9%) required three or more attempts to achieve successful insertion. Reported failures were ascribed to patient anatomy (13), technique (9), airway soiling (7), device (6), trismus (1), high Glasgow Coma Score (1), trauma (1) or unknown (5). This clinical audit provides a comprehensive account of LMA use within SA Ambulance Service. Although the current practice was found to be acceptable, these results are below those of comparable groups and should be improved upon.

Introduction: An epidermoid cyst is a benign cyst usually found on the skin. Bone cysts are very rare and if they appear in bone they usually appear in the distal phalanges of the fingers. Epidermoid cysts of the jaws are uncommon. Case presentation: We present a case, of a 41 year-old female patient admitted to our department because of pain and swelling in the parotid and masseteric region–left side. There was no trismus, pathological findings in skin, high body temperature level, infra-alveolar nerves anesthesia or lymphadenopathy present. The orthopantomography revealed a cystic lesion and a unilocular lesion that included mandibular ramus on the left side with 3 cm in diameter. Under total anesthesia, a cyst had been reached and was enucleated. Histopathologic findings showed that the pathologic lesion was an epidermoid cyst. Discussion: Epidermoid and dermoid cysts are rare, benign lesions found throughout the body. Only a few cases in literature describe an intraossesus epidermoid cyst. Conclusion: Our case is an epidermoid cyst with a rare location in the region of the mandibular ramus. It is not associated with any trauma in this region except medical history reveals there was an operative removal of a wisdom tooth 12 years ago in the same side. These cysts are interesting from the etiological point of view. They should be considered in the differential diagnosis of other radiolucent lesions of the jaws. Surgically they have a very good prognosis, and are non-aggressive lesions. PMID:27594757

Purpose: The purpose of this study was to determine, by treatment plan comparison along with normal tissue complication probability (NTCP) modeling, whether a subpopulation of patients with head and neck squamous cell carcinoma (HNSCC) could be identified that would gain substantial benefit from proton therapy in terms of NTCP. Methods and Materials: For 45 HNSCC patients, intensity modulated radiation therapy (IMRT) was compared to intensity modulated proton therapy (IMPT). Physical dose distributions were evaluated as well as the resulting NTCP values, using modern models for acute mucositis, xerostomia, aspiration, dysphagia, laryngeal edema, and trismus. Patient subgroups were defined based onmore » primary tumor location. Results: Generally, IMPT reduced the NTCP values while keeping similar target coverage for all patients. Subgroup analyses revealed a higher individual reduction of swallowing-related side effects by IMPT for patients with tumors in the upper head and neck area, whereas the risk reduction of acute mucositis was more pronounced in patients with tumors in the larynx region. More patients with tumors in the upper head and neck area had a reduction in NTCP of more than 10%. Conclusions: Subgrouping can help to identify patients who may benefit more than others from the use of IMPT and, thus, can be a useful tool for a preselection of patients in the clinic where there are limited PT resources. Because the individual benefit differs within a subgroup, the relative merits should additionally be evaluated by individual treatment plan comparisons.« less

Patients' factors such as age and sex and surgical variables such as level of difficulty have been linked with surgical outcome in third molar surgery. The aim of this study was to determine the effect of these variables on inflammatory complications in patients undergoing third molar surgery. Patients referred to our institution for surgical extraction of their impacted lower third molar between January 2007 and December 2008 were the subjects of the study. Patients' demographics as well as types of impaction, indication and level of difficulty based on Pederson criteria were obtained. Post operative pain, swelling and mouth opening limitation were evaluated at day 1, day 2, day 3, day 5 and 1 week after the surgery and analyzed. A p value of less than 0.05 was considered significant. A total of 150 patients aged 16-38 years (25.9 ± 4.47) met the inclusion criteria. Male accounted for 66 (44.0 %) while females were 84 (56.0 %), giving male to female ratio of 1:1.3. Age, sex and difficulty index had no effect on pain and trismus throughout the periods of postoperative evaluation (p > 0.05). Postoperative swelling was not affected by gender but patients above 25 years who had high scores of difficulty index had more facial swelling. The results of this study shows that age, gender and the level of surgical difficulty have no effect on pain and mouth opening limitation after third molar surgery.

To assess the effect of platelet-rich fibrin (PRF) on the healing process of the alveolar socket after surgical extraction of the mandibular third molars. PubMed, the Cochrane Central Register of Controlled Trials, Scopus, and relevant journals were searched using a combination of specific keywords ("platelet-rich fibrin," "oral surgery," and "third molar"). The final search was conducted on November 2, 2015. Randomized controlled clinical trials, as well as controlled clinical trials, aimed at comparing the effect of PRF versus natural healing after extraction of mandibular third molars were included. Five randomized controlled trials and one controlled clinical trial were included. There were 335 extractions (168 with PRF and 167 controls) in 183 participants. Considerable heterogeneity in study characteristics, outcome variables, and estimated scales was observed. Positive results were generally recorded for pain, trismus, swelling, periodontal pocket depth, soft tissue healing, and incidence of localized osteitis, but not in all studies. However, no meta-analysis could be conducted for such variables because of the different measurement scales used. The qualitative and meta-analysis results showed no significant improvement in bone healing with PRF-treated sockets compared with the naturally healing sockets. Within the limitations of the available evidence, PRF seems to have no beneficial role in bone healing after extraction of the mandibular third molars. Future standardized randomized controlled clinical trials are required to estimate the effect of PRF on socket regeneration. Copyright © 2017 American Association of Oral and Maxillofacial Surgeons.

To evaluate the use of the temporalis myofascial flap in primary cranial base reconstruction following surgical tumor ablation and to explain technical issues, potential complications, and donor site consequences along with their management. Retrospective case series. Tertiary referral center. Forty-one consecutive patients receiving primary temporalis myofascial flap reconstructions following cranial base tumor resections in a 4-year period. Flap survival, postoperative complications, and donor site morbidity. Patients included 37 males and 4 females ranging in age from 10 to 65 years. Two patients received preoperative and 18 postoperative radiation therapy. Patient follow-up ranged from 4 to 39 months. The whole temporalis muscle was used in 26 patients (63.4%) and only part of a coronally split muscle was used in 15 patients (36.6%). Nine patients had primary donor site reconstruction using a Medpor((R)) (Porex Surgical, Inc., Newnan, GA) temporal fossa implant; these had excellent aesthetic results. There were no cases of complete flap loss. Partial flap dehiscence was seen in six patients (14.6%); only two required surgical débridement. None of the patients developed cerebrospinal leaks or meningitis. One patient was left with complete paralysis of the temporal branch of the facial nerve. Three patients (all had received postoperative irradiation) developed permanent trismus. The temporalis myofascial flap was found to be an excellent reconstructive alternative for a wide variety of skull base defects following tumor ablation. It is a very reliable, versatile flap that is usually available in the operative field with relatively low donor site aesthetic and functional morbidity.

Since the advent of antibiotics, otogenic complications have decreased considerably. However, incomplete antibiotic therapy has altered the clinical course of middle ear disease so as to be more insidious. This paper reports a case of Bezold's abscess associated with cholesteatoma. A 48-year-old man visited our hospital presenting with a 4-day history of right otorrhea and a tender swelling in the right neck. Physical examination showed a febrile patient (38.8 degrees C) with right facial paresis and trismus. A hyperemic, hard and tender swelling was observed in his right neck from the lateral cervical to the mental region. The tympanic membrane was invisible because of granulation and swelling of the posterior wall of the external auditory canal. Intravenous clindamycin and ceftazidime therapy was started immediately. A CT-scan revealed a diffuse shadow with bony destruction in the right mastoid cortex. Extensive abscess formation was also found in the right sternocleidomastoid muscle, in the anterior neck and in the posterior neck. He was diagnosed as having Bezold's abscess associated with cholesteatoma. Radical mastoidectomy and drainage of the neck abscess was performed on the third day under general anesthesia. The mastoid cavity was found to be filled with pus and cholesteatoma debris. A small area of defective bone was found at the mastoid tip, through which there were communications between the mastoid cavity and the abscesses in the neck. Bony destruction was also found in the horizontal and vertical portion of the facial canal. Bacteroides and three kinds of gram-negative rods were cultured from the mastoid cavity.(ABSTRACT TRUNCATED AT 250 WORDS)

Oronasal communication occurs after total maxillectomy for advanced sinonasal cancers. This results in feeding, breathing and cosmetic impairment. Various methods have been described to close off the palatal defect from the oral cavity to improve the function of speech and deglutition. The object of this article is to describe our experience of preservation of palatal mucoperiosteum for oronasal separation. Retrospective review of clinical and operative records of 31 total maxillectomy patients where oronasal separation was achieved by the conventional technique of applying a maxillary obturator. The postoperative complications arising from the use of maxillary obturator for oronasal communication after total maxillectomy in these 31 patients were analysed. To avoid the complications encountered in these 31 patients we preserved and used the ipsilateral palatal mucoperiosteum for oronasal separation. This new technique was applied in 12 patients. The results are presented and compared. A total of 43 patients underwent total maxillectomy for advanced sinonasal tumors. In 31 patients the conventional maxillary obturator was used for oronasal separation. Among these patients, 30 had crustation of the maxillary cavity, nasal regurgitation and cheek skin retraction in 15 each, trismus in eight, infection of skin graft donor site in seven, cheek movement during respiration in five and ill-fitting prosthesis in three. In 12 patients palatal mucoperiosteum was preserved and used for oronasal separation. The complications encountered in oronasal separation by palatal prosthesis were avoided in the modified procedure. We found that oronasal separation by preservation of palatal mucoperiosteum following total maxillectomy allowed excellent palatal function, prompt rehabilitation and minimal complications without compromising the prognosis.

Eagle's Syndrome

2013-01-01

Summary Introduction: Eagle's syndrome is characterized by cervicopharyngeal signs and symptoms associated with elongation of the styloid apophysis. This elongation may occur through ossification of the stylohyoid ligament, or through growth of the apophysis due to osteogenesis triggered by a factor such as trauma. Elongation of the styloid apophysis may give rise to intense facial pain, headache, dysphagia, otalgia, buzzing sensations, and trismus. Precise diagnosis of the syndrome is difficult, and it is generally confounded by other manifestations of cervicopharyngeal pain. Objective: To describe a case of Eagle's syndrome. Case Report: A 53-year-old man reported lateral pain in his neck that had been present for 30 years. Computed tomography (CT) of the neck showed elongation and ossification of the styloid processes of the temporal bone, which was compatible with Eagle's syndrome. Surgery was performed for bilateral resection of the stylohyoid ligament by using a transoral and endoscopic access route. The patient continued to present pain laterally in the neck, predominantly on his left side. CT was performed again, which showed elongation of the styloid processes. The patient then underwent lateral cervicotomy with resection of the stylohyoid process, which partially resolved his painful condition. Final Comments: Patients with Eagle's syndrome generally have a history of chronic pain. Appropriate knowledge of this disease is necessary for adequate treatment to be provided. The importance of diagnosing this uncommon and often unsuspected disease should be emphasized, given that correct clinical-surgical treatment is frequently delayed. The diagnosis of Eagle's syndrome is clinical and radiographic, and the definitive treatment in cases of difficult-to-control pain is surgical. PMID:25992033

Health care faces challenges due to complications, inefficiencies and other concerns that threaten the safety of patients. The purpose of his study was to identify causes of complications encountered after administration of local anaesthesia for dental and oral surgical procedures and to reduce the incidence of complications by introduction of six sigma methodology. DMAIC (Define, Measure, Analyse, Improve and Control) process of Six Sigma was taken into consideration to reduce the incidence of complications encountered after administration of local anaesthesia injections for dental and oral surgical procedures using failure mode and effect analysis. Pareto analysis was taken into consideration to analyse the most recurring complications. Paired z-sample test using Minitab Statistical Inference and Fisher's exact test was used to statistically analyse the obtained data. The p-value <0.05 was considered as significant value. Total 54 systemic and 62 local complications occurred during three months of analyse and measure phase. Syncope, failure of anaesthesia, trismus, auto mordeduras and pain at injection site was found to be most recurring complications. Cumulative defective percentage was 7.99 in case of pre-improved data and decreased to 4.58 in the control phase. Estimate for difference was 0.0341228 and 95% lower bound for difference was 0.0193966. p-value was found to be highly significant with p= 0.000. The application of six sigma improvement methodology in healthcare tends to deliver consistently better results to the patients as well as hospitals and results in better patient compliance as well as satisfaction.

To assess the effect of platelet-rich fibrin (PRF) on postoperative pain, swelling, trismus, periodontal healing on the distal aspect of the second molar, and progress of bone regeneration in mandibular third molar extraction sockets. Over a 2-year period, 31 patients (mean age, 26.1 yr) who required surgical extraction of a single impacted third molar and met the inclusion criteria were recruited. After surgical extraction of the third molar, only primary closure was performed in the control group, whereas PRF was placed in the socket followed by primary closure in the case group (16 patients). The outcome variables were pain, swelling, maximum mouth opening, periodontal pocket depth, and bone formation, with a follow-up period of 3 months. Quantitative data are presented as mean. Statistical significance was inferred at a P value less than .05. Pain (P = .017), swelling (P = .022), and interincisal distance (P = .040) were less in the case group compared with the control group on the first postoperative day. Periodontal pocket depth decreased at 3 months postoperatively in the case (P < .001) and control (P = .014) groups, and this decrease was statistically significant. Bone density scores at 3 months postoperatively were higher in the case group than in the control group, but this difference was not statistically important. The application of PRF lessens the severity of immediate postoperative sequelae, decreases preoperative pocket depth, and hastens bone formation.

Suppurative otitis media is a common childhood infection that predisposes to otogenic tetanus. Tetanus is a vaccine preventable disease that is associated with high cost of care and mortality. This study highlights reasons for otogenic tetanus in Nigerian children and way of reducing the menace. This is a 5-year retrospective review of all patients managed for otogenic tetanus in at the Department of Otorhinolaryngology, University College Hospital, Ibadan. The data collected include demographic, clinical presentations, tetanus immunisation history, and duration of hospital admission, and management- outcome. There were 23 patients comprising of 13(56.5 %) males and 10 (43.5%) females, male to female ratio was 1.3:1. The age ranged between 11 months and12 years (mean age 3.4 years ± 2.1). All the patients presented with discharging ear, trismus and spasms. The onset of symptoms prior hospital presentation ranged between 2 - 11 days (mean 3.0 days ± 1.3). Only 12(52.1%) patients had complete childhood tetanus immunisation, 6(26.1) % had no tetanus immunisation and no other childhood immunisation, while 5(21.7%) had partial tetanus immunisation. The discharging ears were managed by self-medication and other harmful health practices. The hospital admission ranged from 20 days - 41days (average of 23days) and there were 3(13.0 %) death. Tetanus immunization was not received because of; non- availability of the vaccine at health centers, lack of health facility in communities, fear of complications from immunization, poor awareness of the immunization programme. Tetanus, an immunisable disease, is still a major problem in Nigeria.

The purpose of this study was to compare the discomfort and surgical outcomes of a piezosurgery device with those of rotatory instruments in lower third molar extraction. A split-mouth, randomized, unblinded clinical study was designed; the 2 molars had to have the same extraction difficulty score. The test side was extracted using a piezosurgery technique and the control side was extracted using a conventional handpiece. The primary endpoint was patient discomfort evaluated with the Postoperative Symptom Severity (PoSSe) scale, which was administered to each patient; secondary endpoints were pain, trismus, swelling, and surgical time evaluation. Paired-samples t test and repeated-measures analysis of variance were used to compare outcomes within patients. Ten consecutive patients (6 female, 4 male; mean age, 22.4 ± 2.3 yr) were recruited. The total score on the PoSSe scale was significantly lower for piezosurgery compared with the conventional rotating handpiece (24.7 ± 10.3 vs 36.0 ± 7.6; t = -4.27; P = .002). Moreover, postoperative swelling 1 week after surgery was significantly lower for piezosurgery than for the conventional rotating handpiece (2.75 ± 0.23 vs 3.1 ± 0.39 cm; t = -2.63; P = .027). Piezosurgery was associated with less postoperative discomfort and yielded better results for swelling. Piezosurgery seems to be a good technique in daily surgical practice, especially if applied in the critical steps in which safety and respect for soft tissue, bone, and nerves are necessary.

We compared the efficacy of local infiltrative anesthesia and regional mandibular block anesthesia using articaine to harvest ramus grafts and the postoperative sequelae. A total of 20 patients with alveolar bone deficiency participated in the present comparative, prospective, randomized study. The first group received regional anesthesia with the mandibular block technique (group A; n = 10), and those in the second group received local infiltration anesthesia (group B; n = 10). Intraoperative pain and bleeding were evaluated as the primary outcome variables. The visual analog scale (VAS) scores were compared at 0.5, 1, 2, and 4 hours postoperatively. The maximal interincisal mouth opening (MIO) (on days 3 and 7) and VAS scores (at 6, 12, 24, and 48 hours and on days 3 and 7) were compared as secondary outcome variables. The correlation between pain (VAS scores) and trismus (MIO) were also compared. A painless procedure was performed in both groups. The VAS score, MIO, and intraoperative bleeding were not significantly different between the 2 groups. Paresthesia was not observed in either group postoperatively. No statistically significant correlations were found between the VAS scores and MIO. Local infiltrative anesthesia preserves almost the same depth of anesthesia as mandibular block anesthesia. No differences were found between these techniques in terms of efficacy and postoperative sequelae during and after ramus graft harvest. Thus, using articaine with a local infiltration technique is an alternative to mandibular block anesthesia during ramus graft harvesting and results in a reduced risk of inferior alveolar nerve damage.

In man, botulinum toxin type A (BTX) is injected in masticatory muscles for several indications such as trismus, bruxism, or masseter hypertrophy. Bone changes in the mandible following BTX injections in adult animal have therefore became a subject of interest. The aim of this study was to analyze condylar and alveolar bone changes following BTX unilateral injections in masseter and temporal muscles in adult rats. Mature male rats (n = 15) were randomized into 2 groups: control (CTRL; n = 6) and BTX group (n= 9). Rats of the BTX group received a single injection of BTX into right masseter and temporal muscles. Rats of the CTRL group were similarly injected with saline solution. Rats were sacrificed 4 weeks after injections. Masticatory muscles examination and microcomputed tomography (microCT) were performed. A significant difference of weight was found between the 2 groups at weeks 2, 3 and 4 (p < 0.05). Atrophy of the right masseter and temporal muscles was observed in all BTX rats. MicroCT analysis showed significant bone loss in the right alveolar and condylar areas in BTX rats. Decrease in bone volume reached -20% for right alveolar bone and -35% for right condylar bone. A hypertrophic bone metaplasia at the digastric muscle enthesis was found on every right hemimandible in the BTX group and none in the CTRL group. BTX injection in masticatory muscles leads to a significant and major mandible bone loss. These alterations can represent a risk factor for fractures in human. The occurrence of a hypertrophic bone metaplasia at the Mus Digastricus enthesis may constitute an etiological factor for tori. Copyright © 2015 Elsevier Inc. All rights reserved.

The true benefit of autologous platelet concentrates (APCs) for enhancing the healing of postextraction sites is still a matter of debate, and in recent years several clinical trials have addressed this issue. The purpose of this study was to determine the effectiveness of an APC adjunct in the preservation of fresh extraction sockets. An electronic search was performed on Medline, Embase, Scopus, and the Cochrane Central Register of Controlled Trials. Only controlled clinical trials or randomized clinical trials were included. Selected articles underwent risk-of-bias assessment. The outcomes were complications and adverse events, discomfort and quality of life, bone healing and remodeling assessed by histologic and radiographic techniques, and soft tissue healing. Thirty-three comparative studies were included. Nine articles had a parallel design and 24 had a split-mouth design. Twenty studies were considered to have a low risk of bias and 13 were considered to have a high risk. Overall, 1,193 teeth were extracted from 911 patients. Meta-analysis showed that soft tissue healing, probing depth at 3 months, and bone density at 1, 3, and 6 months were statistically better for the APC group. Qualitative analysis suggested that APCs might be associated with a decrease in swelling and trismus. However, no relevant difference among groups was found for probing depth at 1 month, incidence of alveolar osteitis, acute inflammation or infection, percentage of new bone, and indirect measurement of bone metabolism. APCs should be used in postextraction sites to improve clinical and radiographic outcomes such as bone density and soft tissue healing and postoperative symptoms. The actual benefit of APCs on decreasing pain in extraction sockets is still not quantifiable. Copyright © 2017 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc.

Nguyen, T.D.; Demange, L.; Froissart, D.

The authors present a series of 178 patients with Stage III or IV squamous cell carcinoma of the head and neck treated by rapid irradiation using multiple and small fractions per day. An initial group of 91 patients (G1) received a total dose of 72 Gy in 80 sessions and 10 days, according to the following split course schedule: J1 to J5, 36 Gy in 40 sessions, eight daily fractions of .9 Gy separated by 2 hours; J6 to J20, rest period; J21 to J25, same as in J1 except that the spinal cord was shielded. This protocol was alteredmore » for the following 87 patients (G2) by lessening the total dose to 60 to 66 Gy and the number of fractions to 60. The rest period was lengthened to 4 weeks. All patients but five completed the whole program and the minimal follow-up period was 24 months. At the end of irradiation, 121 patients achieved a total remission, but local recurrences occurred in 56%. Moreover, acute intolerance was considered as severe in 34% of G1 patients, and included extensive mucosal necrosis and bleeding. Although this rate was significantly reduced in G2 patients, late complications were observed in 20 of the 25 survivors, and included trismus, cervical sclerosis, and recurrent laryngeal edema. The crude survival rate is 13% at 2 years. Although this study was not randomized, this particular type of accelerated and hyperfractionated combination of irradiation did not really improve the clinical results in advanced carcinoma of the head and neck. Other schedules and probably other tumors, less extended, should be tested.« less

Background Oral cancer is a major public health problem worldwide. It has high mortality rates and chances of survival is relatively superior when detected early. Lack of knowledge and awareness about oral cancer among medical students may contribute to delay in diagnosis and treatment. Objective To assess awareness and knowledge of oral cancer among medical students. Method A cross-sectional study conducted among 286 students by Department of Otorhinolaryngology and Head & Neck surgery, Kathmandu University School of Medical sciences between July to August 2016. A questionnaire with questions on socio-demographic profile, awareness and knowledge of oral cancer was used. Independent sample t test and Pearson Chi-square tests were used for statistical analysis. Result Out of 329 students approached, 286 participated in the study yielding a response rate of 86.9%. Symptoms of oral cancer as reported were ulceration in mouth (92.3%), oral bleeding (85.0%),whitish or reddish patch (84.3%), halitosis (75.5%) and swelling in neck (74.5%), trismus (69.2%), numbness (67.1%), loosening of teeth (49.3%) and tooth sensitivity (41.6%). The perceived risk factors were smoking (97.2%), tobacco chewing (96.5%), chronic irritation (86.7%), immunodeficiency (83.9%), poor oral hygiene (88.5%), human papilloma virus infection (82.5%), dietary factors (81.1%), alcohol (79.4%), ill-fitting dentures (72.4%), hot spicy food (65.4%) and hot beverages (58.0%). Significant differences were found between pre-clinical and clinical students for knowledge of risk factors, signs and symptoms of oral cancer (p<0.001). Conclusion There is deficiency of knowledge among medical students about some aspects of oral cancer. Active involvement while examining patients and taking biopsies of malignant and premalignant lesions may help in improving students' knowledge about oral cancer.

Introduction A tooth is said to be impacted if it does not reach the occlusal plane even after two-thirds root formation. The aetiology of impacted teeth is varied and multi-factorial. Significant problems associated with impacted teeth include trismus, infection, cervical caries of second molars. Aim This study was aimed to assess the prevalence of distal caries in second molar teeth due to impacted third molars and to compare with similar studies conducted elsewhere. Materials and Methods Study included assessment of patients reporting between 2009 to 2014 for dental care at College of Dentistry, King Khalid University, Abha, Kingdom of Saudi Arabia. This is a retrospective cross-sectional study which included a total of 6000 Orthopantomograms (OPGs). The data collected was decoded and entered into excel spread sheet. Descriptive analysis of the data was done and results were displayed as frequency table and graphs. Results A total of 979 patients had impacted third molars (16.31%). A total of 39% patient’s with impacted third molars had distal cervical caries in second molar. Mesioangular impaction was the most prominent type. This was closely followed by horizontal impaction causing distal caries in second molars. Age group between 21-28 years and male gender had the higher prevalence of distal caries in second molar teeth due to impacted third molars. Conclusion A total of 39% of the patients with impacted mandibular third molars had distal cervical caries in second molars. Mesioangular type, male gender, age group 21-28 years were the prominent factors associated with distal caries in second molar teeth due to impacted third molars. PMID:28511504

Noone, Jennifer; Barclay, Craig

2017-03-01

Salivary gland damage is the most common adverse effect associated with radiation therapy to the head and neck. A combination of hyposalivation and dietary changes, with a reduced emphasis on oral hygiene practices can contribute to a massive increase in a person’s caries risk status. This can be further complicated by limited mouth opening. To enable optimal dental care for head and neck cancer patients before, during and after radiation therapy, patients must be informed and educated about the potential risks of dental caries and the preventive strategies available. All patients should receive a pre-radiotherapy dental assessment by a Restorative Dentistry Consultant. This information will be delivered to the patient, often at an emotionally charged time, and can be lost amongst all the information related to other aspects of his/her cancer management. General Dental Practitioners (GDPs) are therefore in a pivotal position to reiterate this information post radiation therapy and ensure compliance with preventive strategies, with the overall aim to improve quality of life and avoid the need for future extractions and the resulting risk of osteoradionecrosis. Clinical relevance: This article highlights the GDP’s role in the shared management of head and neck cancer patients who have received radiotherapy as part of their cancer treatment. The critical issue of dental caries, one of the late effects of radiation-induced hyposalivation, will be focused upon. Other side-effects, such as trismus and osteoradionecrosis, will also be discussed. This article aims to supply GDPs with accurate information to provide to their patients with post radiation therapy, whilst highlighting what treatment is within their remit and when it may be appropriate to refer.

Ankylosis of the temporomandibular joint (TMJ) is a debilitating condition that can result in pain, trismus, and a poor quality of life. It can be caused by injury, infection, and rheumatoid disease. Current management includes gap arthroplasty, interpositional arthroplasty, and reconstruction. Traditionally, joints are reconstructed using stock implants, or the procedure is done in two stages with an additional computed tomography (CT) scan between the resective and reconstructive procedures and use of stereolithographic models to aid the design of the definitive prostheses. We describe a technique for the resection of ankylosis and reconstruction of the joint in a single operation using virtually designed custom-made implants. Five patients with ankylosis of the TMJ had a single stage operation with reconstruction between 2010 and 2012. All had preoperative high-resolution CT with contrast angiography. During an international web-based teleconference between the surgeon and the engineer a virtual resection of the ankylosis was done using the reconstructed CT images. The bespoke cutting guides and implants were designed virtually at the same time and were then manufactured precisely using computer-aided design and manufacture (CAD-CAM) over 6 weeks. After release of the ankylosis and reconstruction, the patients underwent an exercise regimen to improve mouth opening. Follow-up was for a minimum of 6 months. Four patients had one operation, and one patient had two. Median/Mean maximum incisal opening increased from 0.6mm before operation to 25 mm afterwards (range 23-27), and there was minimal surgical morbidity. This new method effectively treats ankylosis of the TMJ in a single stage procedure. Fewer operations and hospital stays, and the maintenance of overall clinical outcome are obvious advantages.

To assess the antibiotic prescribing patterns of South African dentists for patients undergoing endodontic treatment. This study used data from 2013 health insurance claims submitted by South African oral health professionals to determine the antibiotic prescribing patterns related to endodontic treatment. A logistic regression model was used to test the fully adjusted statistical significance of the association between the exploratory variables (gender, age group, event type, abscess treatment, chronic health) and the dependent variable (antibiotic prescription). Odds ratios with 95% confidence intervals (CI) are reported, and a 95% CI excluding 1 was considered statistically significant. Almost 10% of endodontic treatments were prescribed an antibiotic. There were no significant differences in prescribing patterns by gender, age and chronic health status. Prescriptions were more common at the preparatory stage (9.4%) of root canal treatment compared to the therapy (4.7%) and canal filling (2%) stages. Patients who received apical surgery (OR = 2.28; 95% CI 1.38-3.76) and treatment of an abscess (OR = 2.57; 95% 1.82-3.63) had a significantly increased odds of being prescribed an antibiotic. Almost three-quarters of prescriptions were for narrow spectrum antibiotics. The frequency of antibiotic prescribing by South African dental practitioners for patients undergoing endodontic treatment is relatively low and predominantly involved narrow spectrum antibiotics. It, however, remains important that antibiotics are only prescribed when clinically essential, such as when there are obvious systemic effects. These include fever above 37 degrees, malaise, lymphadenopathy, trismus, increase swelling, cellulitis, osteomyelitis and persistent infection. The wider dissemination and adherence to clear evidence-based prescribing guidelines for antibiotics in this clinical area are important. © 2016 International Endodontic Journal.

A history of noma, the "Face of Poverty".

PubMed

Marck, Klaas W

2003-04-15

Noma (necrotizing ulcerative stomatitis, stomatitis gangrenosa, or cancrum oris) is a devastating orofacial gangrene that occurs mainly among children. The disease has a global yearly incidence of 140,000 cases and a mortality rate of approximately 90 percent. Patients who survive noma generally suffer from its sequelae, including serious facial disfigurement, trismus, oral incontinence, and speech problems. The medical history of noma indicates that the disease was already known in classical and medieval civilizations in Europe. In the sixteenth and seventeenth centuries, Dutch chirurgeons clearly described noma as a clinical entity and realized that the popular name "water canker" was not sufficient, because this quickly spreading ulceration in the faces of children was different from "cancer." In the eighteenth century, awareness that noma is related to poverty, malnutrition, and preceding diseases such as measles increased in northwestern Europe. In the first half of the nineteenth century, extensive surgical procedures were described for the treatment of the sequelae of noma. At the end of that century, noma gradually disappeared in the Western world because of economic progress, which gave the poorest in society the opportunity to feed their children sufficiently. Only in the twentieth century were effective drugs (sulfonamides and penicillin) against noma developed, as well as adequate surgical treatment for the sequelae of noma. These modes of treatment remain inaccessible for the many present-day victims of noma because of their extreme poverty. The only truly effective approach to the problem of noma throughout the world is prevention, namely, combating the extreme poverty with measures that lead to economic progress. In the meantime, medical doctors in the Western world should not forget their own history and ignore this global health problem; rather, they should face "the face of poverty" with the eyes of mercy and concern suited to their profession.

Application of platelet-rich fibrin (PRF) during tooth extraction is able to accelerate wound healing, stimulate osseous and soft tissue regeneration, and reduce unwanted side effects. The aim of this meta-analysis was to investigate the effect of local application of PRF on controlling postoperative signs and symptoms after the extraction of an impacted lower third molar. A systematic search of PubMed, Web of Science, Embase, and the Cochrane Library was performed to identify all studies published up to October 2016 that investigated the effect of PRF on lower third molar extraction. Pain, swelling, trismus, alveolar osteitis (AO), and osteoblastic activity were extracted to evaluate the effect of PRF. After quality assessment, meta-analysis was performed with RevMan software (version 5.3; Cochrane Library Software, Oxford, UK). After the search and selection process, 10 studies were selected in this meta-analysis, including 468 cases of PRF application and 467 cases of non-PRF application. Of the studies, 9 were randomized controlled trials, including 7 split-mouth studies, and there was 1 retrospective case-control study. The results indicated that PRF significantly relieves pain (P = .01) and 3-day postoperative swelling (P = .03) and reduces the incidence of AO (P < .0001). However, there were no significant differences between the PRF and non-PRF groups with respect to 1-day postoperative swelling and osteoblastic activity. Local application of PRF after lower third molar extraction is a valid method for relieving pain and 3-day postoperative swelling and reducing the incidence of AO. For patients undergoing complicated surgical extraction, PRF might be a recommendation for local application into the sockets.

Hyaluronic acid (HA) has a number of clinical applications in current practice. Therefore, correlation of HA with free radicals and inflammatory cells is clinically important. The purpose of this study is to measure the efficacy of high molecular weight HA on the oxidative stress of oral wounds (glutathione (GSH) and lipid peroxidation (LPO) levels), the inflammatory reaction (leucocytes, collagen and angiogenesis content), pain (visual analogue scale (VAS) records) and trismus (maximum interincisal opening (MIO) records) after third molar (M3) extraction. 40 patients were included in this study. 0.2 ml 0.8% HA was applied immediately after surgery within the HA group (n = 20). Nothing was applied to the control group (n = 20). The primary outcome variables were the changes in the inflammatory reaction (leucocyte, angiogenesis and collagen content), oxidative stress (GSH, LPO) and clinical parameters (VAS, MIO). Results were compared immediately after extraction (T0) and 1 week after surgery (T1). Bivariate analyses were used to assess the differences between the HA and control groups for each study variable. There was a statistically significant difference of leucocyte infiltration and angiogenesis between the groups at T1. The HA group showed less leucocyte infiltration and more angiogenesis than the control group. There was no statistically significant difference in oxidative stress, VAS or MIO levels between the groups. Our results confirm the hypothesis that HA has an anti-inflammatory effect following M3 extraction. However, the oxidative stress levels and clinical outcomes were similar after one week. Further studies examining these parameters at different times are necessary. Copyright © 2015 European Association for Cranio-Maxillo-Facial Surgery. Published by Elsevier Ltd. All rights reserved.

2012-04-01

Purpose: Our practice policy has been to provide intraoperative radiotherapy (IORT) at resection to patients with head-and-neck malignancies considered to be at high risk of recurrence. The purpose of the present study was to review our experience with the use of IORT for primary or recurrent cancer of the parotid gland. Methods and Materials: Between 1982 and 2007, 96 patients were treated with gross total resection and IORT for primary or recurrent cancer of the parotid gland. The median age was 62.9 years (range, 14.3-88.1). Of the 96 patients, 33 had previously undergone external beam radiotherapy as a component ofmore » definitive therapy. Also, 34 patients had positive margins after surgery, and 40 had perineural invasion. IORT was administered as a single fraction of 15 or 20 Gy with 4-6-MeV electrons. The median follow-up period was 5.6 years. Results: Only 1 patient experienced local recurrence, 19 developed regional recurrence, and 12 distant recurrence. The recurrence-free survival rate at 1, 3, and 5 years was 82.0%, 68.5%, and 65.2%, respectively. The 1-, 3-, and 5-year overall survival rate after surgery and IORT was 88.4%, 66.1%, and 56.2%, respectively. No perioperative fatalities occurred. Complications developed in 26 patients and included vascular complications in 7, trismus in 6, fistulas in 4, radiation osteonecrosis in 4, flap necrosis in 2, wound dehiscence in 2, and neuropathy in 1. Of these 26 patients, 12 had recurrent disease, and 8 had undergone external beam radiotherapy before IORT. Conclusions: IORT results in effective local disease control at acceptable levels of toxicity and should be considered for patients with primary or recurrent cancer of the parotid gland.« less

The most common sequelae after surgical removal of mandibular third molar are pain, trismus, swelling, and dysphagia. However, these symptoms can also signal the onset of surgical site infection and alveoli osteitis. The aim of this study was to evaluate the efficacy of prophylactic amoxicillin/clavulanic acid and levofloxacin and preemptive therapy of amoxicillin/clavulanic acid in the reduction of postinflammatory complications, surgical site infection, and alveolar osteitis following the third molar surgery. A total of 135 patients were randomized into three equal groups: Group A (preemptive therapy of amoxicillin/clavulanic acid) with preoperative dose of 875/125 mg amoxicillin/clavulanic acid followed by 500/125 mg amoxicillin/clavulanic acid 12 hourly for 5 days, Group B (amoxicillin/clavulanic acid prophylaxis) with a single preoperative dose of amoxicillin/clavulanic acid 875/125 mg tablets, and Group C (levofloxacin prophylaxis) with a single preoperative dose of levofloxacin 1000 mg tablets. All patients had ostectomy using surgical handpiece and burs and received same analgesics (tabs ibuprofen 400 mg 8 hourly for 3 days). No case of surgical site infection or alveoli osteitis was recorded in the study groups. There were no statistically significant differences between the treatment groups with regard to pain, mouth opening, postoperative facial dimension, and body temperature. Amoxicillin/clavulanic acid as a single preoperative bolus should be adequate for the prevention of postoperative wound infection and alveoli osteitis following the third molar extraction as there is no need for an extension of the antibiotic. Moreover, levofloxacin can be utilized as prophylaxis in patients undergoing mandibular third molar extraction if such patients are allergic to penicillins.

Introduction: Antibiotic resistance is now a serious problem, although it was not so only a few years ago. The need of the hour is to give clear evidence of the efficacy of antibiotic use, or lack thereof, to the surgeon for a procedure as common as mandibular third molar surgery. Aim: This study aimed to evaluate whether postoperative combined amoxicillin and clavulanic acid in mandibular third molar extraction is effective in preventing inflammatory complications. Study and Design: The study was structured as a prospective randomized double-blind placebo-controlled clinical trial. Materials and Methods: A study was designed wherein the 96 units (two bilaterally similar impacted mandibular third molars per head in 48 patients) were randomly assigned to two treatment groups (Group I and Group II). Each patient served as his/her own control. Each patient received 625 mg of combined amoxicillin and clavulanic acid 1 h before surgery. In the case of third molars belonging to Group I, 625 mg of combined amoxicillin and clavulanic acid TDS was continued for 3 days; in Group II, placebo in similar-looking packs was continued for 3 days. The patients were evaluated on the third and seventh postoperative days for signs of clinical infection and for microbial load evaluation. Statistical Analysis: The data between the two groups were statistically analyzed by the two-tailed Fisher's exact test, with a 95% confidence interval. Results: The difference was not statistically significant between the test group and the control group with regard to erythema, dehiscence, swelling, pain, trismus, and infection based on microbial load. The data were statistically significant for alveolar osteitis, with the occurrence of alveolar osteitis (14.58%) in the placebo group. Conclusion: Postoperative antibiotics are recommended only for patients undergoing contaminated, long-duration surgery. PMID:25937728

Purpose: Local recurrences of nasopharyngeal carcinoma (NPC) may be salvaged by reirradiation with conventional techniques, but with significant morbidity. Intensity-modulated radiation therapy (IMRT) may improve the therapeutic ratio by reducing doses to normal tissue. The aim of this study was to address the efficacy and toxicity profile of IMRT for a cohort of patients with locally recurrent NPC. Methods and Materials: Between August 2003 and June 2009, 70 patients with radiologic or pathologically proven locally recurrent NPC were treated with IMRT. The median time to recurrence was 30 months after the completion of conventional radiation to definitive dose. Fifty-seven percentmore » of the tumors were classified asrT3-4. The minimum planned doses were 59.4 to 60 Gy in 1.8- to 2-Gy fractions per day to the gross disease with margins, with or without chemotherapy. Results: The median dose to the recurrent tumor was 70 Gy (range, 50-77.4 Gy). Sixty-five patients received the planned radiation therapy; 5 patients received between 50 and 60 Gy because of acute side effects. With a median follow-up time of 25 months, the rates of 2-year locoregional recurrence-free survival, disease-free survival, and overall survival were 65.8%, 65.8%, and 67.4%, respectively. Moderate to severe late toxicities were noted in 25 patients (35.7%). Eleven patients (15.7%) had posterior nasal space ulceration, 17 (24.3%) experienced cranial nerve palsies, 12 (17.1%) had trismus, and 12 (17.1%) experienced deafness. Extended disease-free interval (relative risk 2.049) and advanced T classification (relative risk 3.895) at presentation were adverse prognostic factors. Conclusion: Reirradiation with IMRT provides reasonable long-term control in patients with locally recurrent NPC.« less

To compare surgery and postoperative radiotherapy (PORT) with the non-surgical combination of chemotherapy and radiation therapy (CCRT) for locally advanced squamous cell carcinoma (SCC) of the tonsil by measuring treatment outcomes and treatment-related complications. The records of 114 patients with non-metastatic stage III/IV tonsillar SCC treated between July, 1998 and December, 2010 were reviewed retrospectively. Among the 114 patients, 65 received PORT and 49 received CCRT. In the PORT group, treatment included wide surgical resection of the tumor with neck dissection and administration of PORT to the primary tumor bed with a median dose of 60 Gy. In the CCRT group, a median dose of 70 Gy was delivered to the gross tumor, and 46 patients received concurrent chemotherapy with i.v. cisplatin. The median follow-up time was 58 months in the PORT group and 44 months in the CCRT group. There was no significant difference between PORT and CCRT in terms of 5-year locoregional recurrence-free survival (88.4% vs. 91.4%, p=0.68), distant metastasis-free survival (88.9% vs. 92.3%, p=0.60), disease-free survival (79.5% vs. 84.2%, p=0.63) or overall survival (78.9% vs. 88.9%, p=0.45). More CCRT patients than PORT patients experienced grade 3 (or higher) hematological toxicities and grade 2 pharyngitis during treatment. Chronic toxicity, manifested as swallowing difficulty, dry mouth and trismus, was similar between the two treatment groups. CCRT provides similar levels of local and distant control in patients with locally advanced tonsillar SCC as PORT, yet fails to show any superiority in preserving functions such as swallowing, saliva production, and mastication.

The most common complications after surgical extraction of the third mandibular molar are trismus, oedema or swelling, local pain, dysphagia and infection. The aim of this comparative, double-blind, randomized clinical trial was to evaluate the efficacy of two sustained release amoxicillin/clavulanate regimens in the reduction of infection after third molar extractive surgery. A total of 225 patients were randomized into three equal groups: placebo, prophylaxis with single pre-surgical dose of two tablets amoxicillin/clavulanate 1000/62.5 mg, and pre-emptive post-surgery therapy with two tablets amoxicillin/clavulanate 1000/62.5 mg BID for 5 days. A higher rate of infection (P=0.006) was found among patients receiving placebo (16%) than those receiving single-dose prophylaxis (5.3%) or 5-day pre-emptive therapy (2.7%). A relationship between both the duration (13.8% for long versus 7.4% for medium versus 1.6% for short) and difficulty (12.7% with ostectomy versus 3.5% without ostectomy; P=0.011) of surgical procedure and incidence of subsequent infection was also observed. Both prophylactic and therapeutic regimens versus placebo achieved greater reduction of pain after surgery on day 3 (P=0.001). Logistic regression analysis revealed a risk of infection of 24%, 9% and 4% for ostectomy with placebo, prophylaxis and pre-emptive treatment, respectively, whereas it was 7%, 2% and 1% if ostectomy was not performed. Pre-emptive therapy with the oral sustained release amoxicillin/clavulanate formulation reduced the rate of subsequent infection in patients undergoing ostectomy. Prophylaxis was beneficial in simpler procedures and may be indicated in cases where ostectomy is not performed.

Temporomandibular joint pain dysfunction syndrome (TMJPDS) is the most common temporomandibular disorder. This condition presents with symptoms of pain, restricted jaw movement and joint noise. Other symptoms include otalgia, headache, neck pain and trismus. To determine the pattern of Temporomandibular joint pain dysfunction syndrome patients managed at the Lagos University Teaching Hospital, Lagos, Nigeria. A descriptive study of patients with signs and symptoms of Temporomandibular joint pain dysfunction syndrome attending the Oral Medicine Clinic of Lagos University Teaching Hospital. Twenty-one patients with Temporomandibular joint pain dysfunction syndrome were enrolled into the study, out of which 10(48%) were females and 11(52%) were males. The age range was 23-81years with a mean of 45.2 ± 18.9 years. Majority of the patients 20(95.2%) complained of pain around the joint, in the pre-auricular region, in the muscles of mastication and the ear. While 7(35%) complained of clicking sounds, 10(47.6%) complained of pain on mouth opening and during mastication only. In all 5(23.8%) had impaired movement of the jaws, mouth opening was normal in 18(85.7%) but reduced in 3(14.3%) patients. Over half of patients 12(57%) experienced clicking sounds, there was tenderness around the temporomandibular joint in 16(76.2%) cases, pain in the ear of 7(33.3%) patients and 13(61.9%) people presented with tenderness of the muscles of mastication. Conservative management of all the cases resulted in resolution of the symptoms. Temporomandibular joint pain dysfunction syndrome has diverse clinical presentation and though distressing, it responds to prompt and effective conservative management.

The primary aim of the present study was to evaluate the effectiveness of postoperative irrigation of the socket with drinking tap water on inflammatory complications following lower third molar removal. A multicenter randomized controlled trial was carried out from June 2013 to June 2014. In one arm of the study, patients were instructed to irrigate the tooth socket and surgical site with a Monoject® Curved 412 Tip Syringe (Tyco/healthcare-Kendall, Mansfield, MA, USA) with tap water. In a second arm of the study, the standard postoperative instructions did not include irrigation instructions. The incidences of alveolar osteitis and wound infection were recorded for each group and analyzed by the Fisher's exact test. A total of 280 patients with 333 mandibular third molars were analyzed. According to the intention-to-treat (ITT) analysis, inflammatory complications occurred in 18 cases in the Monoject® group (11.4 %) compared to 34 cases (19.1 %) in the control group (p = 0.04). These complications were associated with significant worse outcomes regarding quality of life, pain, and trismus and caused significantly more missed days of work or study. Female gender, age >26, bone removal, deep impacted third molars, less experienced surgeons, and a high amount of debris at the surgical site were also identified as risk factors for developing inflammatory complications following lower third molar removal. Irrigation of the surgical site with drinking tap water using a curved syringe following removal of third molars is effective in reducing the risk of inflammatory complications. Water is a very accessible, cost-effective irrigant without side effects and the results from this study have proven that it can be used to reduce the risk of inflammatory complications and associated morbidity following lower third molar removal.

Introduction: The aim of this study was to assess the effect of low-level laser therapy (LLLT) on pain, swelling and maximum mouth opening in patients undergoing third molar surgery. Methods: A prospective, randomized double-blind study was undertaken on 44 patients at the Dental School, Ahvaz Jundishapur University of Medical Sciences, in 2015. A low-level laser was randomly applied on one of the two sides after surgery of 15 patients. The experimental side received 18 J/cm2 of energy density, wavelength of 980 nm, and output power of 1.8 W. On the control side, a hand-piece was applied intra-orally, but laser was not activated. In addition, in order to evaluate trismus, 13 patients were treated by unilateral laser therapy and 16 patients did not receive laser therapy at all. The laser was administered intraorally on two points of vestibular and lingual sides at 1 cm from the surgery site, and extraorally at the emergence of the masseter muscle, immediately after surgery, and repeated 24 hours later. The pain, swelling and maximum mouth opening (MMO) were compared between the two groups at 24 hours and a week after surgery. Results: The mean score of pain 24 hours after surgery in the laser therapy group (2.3 ± 3.5) was significantly lower than the mean score of pain in the drug therapy (4.19 ± 3.09) (P = 0.036). Moreover, the mean score of pain at one week after surgery in the laser therapy group (0.13 ± 2.33) was significantly lower than the drug therapy group (1.43 ± 2.45) (P = 0.046). The amount of swelling according to different measurements did not significantly differ between the two groups neither at 24 hours nor at 1 week after surgery. Conclusion: Our findings showed that LLLT was useful in reducing pain and could slightly reduce swelling compared to drug therapy in impacted third molar surgery. PMID:28912943

Tetanus is a life threatening preventable infection relatively uncommon in the developed world but occurs frequently in developing countries with case fatality rate of 40-60%. We conducted the study as there is no recent review regarding adult tetanus in Ethiopia which looked at the predisposing factors, presenting features and case fatality rate. The study aims to evaluate clinical characteristics of adult tetanus as related to predisposing factors, presenting features and treatment outcome. This is a retrospective review of adult tetanus cases admitted to medical ward of Gondar University Hospital, North West Ethiopia, over a period of 5-years. A total of 29 adults were admitted with the diagnosis of generalized tetanus during the study period. There were more male then female patients (sex ratio 1.9:1) with rural dwellers constituting the majority. The mean age of patients was 35 +/- 14 yrs (range, 18-70 yrs. Majority of patients (72.4%) sustained acute injury preceding symptom onset, often on lower extremity. Three rural mothers, who denied history of trauma, developed puerperal tetanus with in 2 weeks of delivery, genital tract thought to be the portal of entry. Almost all patients, who had sustained acute injury, did not seek medical help for their wounds and missed the chance to receive prophylaxis for tetanus. Over all, 48.3% had severe, 37.9% moderate, and 13.8% mild form of tetanus at presentation. The most common clinical presentation was trismus (100%), followed by stiff neck and back (93.1%) and neck rigidity (86.2).Over all mortality rate was 41.4%. Respiratory failure requiring ventilatory support (66.7%) was the major cause of death. The study recommends a need for tetanus immunization in those who had acute injury and planning to educate individuals at risk to recognise symptoms early, and seek medical care to combat this fatal disease.

The authors hypothesized that an audiovisual slide presentation that provided treatment information regarding the removal of an impacted mandibular third molar could improve patient knowledge of postoperative complications and decrease anxiety in young adults before and after surgery. A group that received an audiovisual description was compared with a group that received the conventional written description of the procedure. This randomized clinical trial included young adult patients who required surgical removal of an impacted mandibular third molar and fulfilled the predetermined criteria. The predictor variable was the presentation of an audiovisual slideshow. The audiovisual informed group provided informed consent after viewing an audiovisual slideshow. The control group provided informed consent after reading a written description of the procedure. The outcome variables were the State-Trait Anxiety Inventory, the Dental Anxiety Scale, a self-reported anxiety questionnaire, completed immediately before and 1 week after surgery, and a postoperative questionnaire about the level of understanding of potential postoperative complications. The data were analyzed with χ(2) tests, independent t tests, Mann-Whitney U  tests, and Spearman rank correlation coefficients. Fifty-one patients fulfilled the inclusion criteria. The audiovisual informed group was comprised of 20 men and 5 women; the written informed group was comprised of 21 men and 5 women. The audiovisual informed group remembered significantly more information than the control group about a potential allergic reaction to local anesthesia or medication and potential trismus (P < .05). The audiovisual informed group had lower self-reported anxiety scores than the control group 1 week after surgery (P < .05). These results suggested that informing patients of the treatment with an audiovisual slide presentation could improve patient knowledge about postoperative complications and aid in alleviating anxiety after the surgical removal of an impacted mandibular third molar.

To evaluate the effect of ice pack therapy on oral health-related quality of life (OHRQoL) following third molar surgery. All consecutive subjects who required surgical extraction of lower third molars and satisfied the inclusion criteria were randomly allocated into two groups. Subjects in group A were instructed to apply ice packs directly over the masseteric region on the operated side intermittently after third molar surgery. This first application was supervised in the clinic and was repeated at the 24-h postoperative review. Subjects in group A were further instructed to apply the ice pack when at home every one and a half hours on postoperative days 0 and 1 while he/she was awake as described. Group B subjects did not apply ice pack therapy. Facial swelling, pain, trismus, and quality of life (using Oral Health Impact Profile-14 (OHIP-14) instrument) were evaluated both preoperatively and postoperatively. Postoperative scores in both groups were compared. A significant increase in the mean total and subscale scores of OHIP-14 was found in both groups postoperatively when compared with preoperative value. Subjects who received ice pack therapy had a better quality of life than those who did not. Subjects whose postoperative QoL were affected were statistically significantly higher in group B than in group A at all postoperative evaluation points (P < 0.05). Statistically significant differences were also observed between the groups in the various subscales analyzed, with better quality of life seen among subjects in group A. Quality of life after third molar surgery was significantly better in subjects who had cryotherapy after third molar than those who did not have cryotherapy. Cryotherapy is a viable alternative or adjunct to other established modes of improving the quality of life of patients following surgical extraction of third molars.

Objectives The purpose of this study was to assess the pattern of third molar impaction and associated symptoms in a Central Anatolian Turkish population. Material and Methods A total of 2,133 impacted third molar teeth of 705 panoramic radiographs were reviewed. The positions of impacted third molar teeth on the panoramic radiographs were documented according to the classifications of Pell and Gregory and of Winter. The presence of related symptoms including pain, pericoronitis, lymphadenopathy and trismus was noted for every patient. Distributions of obtained values were compared using the Pearson χ2 test. Nonparametric values were analyzed using the Mann-Whitney U test and Kruskal-Wallis test. Results The mean age of the subjects was 30.58 ± 11.98 years (range: 19-73); in a review of the 2,133 impacted third molar teeth, the most common angulation of impaction in both maxillaries was vertical (1,177; 55%). Level B impaction was the most common in the maxilla (425/1,037; 39%), while level C impaction was the most common in the mandible (635/1,096; 61%). Pain (272/705; 39%) and pericoronitis (188/705; 27%) were found to be the most common complications of impaction. Among 705 patients (335 males, 370 females), pericoronitis was more prevalent in males (101; 30%) and usually related to lower third molars (236; 22%). The retromolar space was significantly smaller in females (p < 0.05). Moreover, there was a significant difference in retromolar space for the area of jaw (maxillary: 11.3 mm; mandibular: 14.2 mm) and impaction level (A: 14.7 mm; B: 11.1 mm; C: 10.3 mm; p < 0.05). Conclusion The pattern of third molar impaction in a Central Anatolian Turkish population was characterized by a high prevalence rate of level C impaction with vertical position. Pain and pericoronitis were the most common symptoms usually associated with level A impaction and vertical position. PMID:26566129

Introduction: Surgical extraction of impacted mandibular third molars is often associated with sequelae such as postoperative pain, facial edema, and limitation in mouth opening ability. These sequelae may result in changes in the patients’ lifestyle and quality of life (QoL). Aim: The aim of this study was to evaluate the effect of surgical extraction of impacted mandibular third molars on patients’ QoL in the immediate postoperative period (7 days). Materials and Methods: Ethical approval for this study was obtained from the Health Research and Ethics committee of the Lagos University Teaching Hospital. A total of 124 individuals with impacted mandibular third molars, who satisfied the inclusion criteria and consented to participate in this study, were included. The Oral Health Impact Profile-14 (OHIP-14) QoL questionnaire was used to assess QoL. QoL was assessed preoperatively (baseline) and on postoperative days (PODs) 1, 3, and 7. Maximal interincisal mouth opening, facial width, and pain were also reviewed at all evaluation points. Data analysis was done using the Statistical Package for Social Sciences (SPSS) for Windows (version 16.0, Chicago, IL, USA). Results: A total of 124 individuals were included in the final analysis. An age range of 18–51 years with a mean (±standard deviation) of 28.5 (7.4) years was observed. A male to female ratio of 1:1.5 was observed. The most frequently encountered type of impaction was the mesioangular impaction 51 (41.1%) and recurrent pericoronitis was the principal reason for extraction 53 (42.7%). The severity of the sequelae (pain, trismus, and facial edema) was maximal on the first POD. Patients’ overall QoL deteriorated sharply on the first POD and subsequently improved. Conclusion: Surgical extraction of mandibular third molars is associated with worsening of patients’ postoperative QoL in the immediate postoperative period. Prospective patients should be informed about this, and ways of reducing this untoward effect should be explored. PMID:29326504

Disease-specific adverse events following nonlive vaccines: a paradoxical placebo effect or a nocebo phenomenon?

Vaccines can cause adverse reactions (AR), i.e. adverse events following immunization (AEFIs) due to the vaccine, such as local reactions or fever. In addition, live attenuated vaccines which replicate in vaccinees can cause disease-specific AR, e.g. measles-like rash following measles vaccination. However, nonlive vaccines because they are inactivated and they do not replicate in vaccinees, are not likely to cause disease-specific AR. The aim of the study was to assess whether safety signals could be generated by an undescribed bias in spontaneous reporting of disease-specific AEFIs with nonlive vaccines. All AEFIs of Sanofi Pasteur MSD vaccines spontaneously reported in France from January 2000 to June 2010, coded according to MedDRA terms and collected in the company's pharmacovigilance database were analyzed. Vaccine-event pairs of interest were selected a priori. The disproportionality reporting rate methodology was used, comparing the proportion of a given event reported following a given vaccine to its proportion reported following all other studied vaccines. The Reporting Odds Ratio (ROR) was used for signals detection for each vaccine-event pair selected. A total of 33,275 AEFIs were analyzed. The calculated ROR showed a statistically disproportionate reporting rate and generated false safety signals for almost all the pairs tested. Three nonlive vaccine pairs were striking: gynaecological symptoms and the quadrivalent human papillomavirus (qHPV) vaccine; trismus and tetanus vaccines; hepatobiliary disorders and hepatitis B vaccines. In conclusion we have identified a new vaccine AE spontaneous reporting bias: "disease-specific adverse events following nonlive vaccines", showing that vaccinees and healthcare professionals tend to report preferentially the symptoms of the disease against which the nonlive vaccine was administered. We suggest that bias is subordinate to a paradoxical placebo effect and/or a nocebo phenomenon. Copyright © 2011 Elsevier Ltd. All rights reserved.

Septic arthritis of the temporomandibular joint (SATMJ) is a very rare but potentially severe complication of pediatric middle ear infections because it presents risks of TMJ ankylosis. To describe the clinical, radiological, biological, and microbiological characteristics and evolution of SATMJ complicating middle ear infections (otogenic SATMJ) in children. This multicenter retrospective study included all children younger than 18 years referred between January 1, 2005, and December 31, 2015, for otogenic SATMJ or for TMJ ankylosis that occurred a few months to a few years after an acute mastoiditis. Nine children were included in the study. Review of the children's medical charts was conducted from February 1, 2016, to April 1, 2016. Patients' demographic characteristics and symptoms; radiological, biological, and bacteriological findings, including reanalysis of initial imaging; and treatment and outcome of SATMJ. Of the 9 children, 6 were boys and 3 were girls; the mean age was 2.1 years (range, 6 months to 4.7 years). In 7 cases (78%), the primary middle ear infection was acute mastoiditis. Clinically, 5 children (55%) had preauricular swelling and only 1 (11%) had trismus. Associated thrombophlebitis of the lateral sinus or intracranial collections was present in 7 cases (78%). An initial computed tomographic scan was performed for all but 1 patient, and second-line analysis detected clear signs of TMJ inflammation in all 8 children who had a computed tomographic scan. However, SATMJ was diagnosed in only 3 cases at the time of the initial middle ear infection, leading to the recommendation of TMJ physical therapy for several months. The most frequently involved bacteria was Fusobacterium necrophorum, which was found in 4 cases. Long-term ankylosis was identified in 6 cases (67%), and 5 of these children required surgical treatment. Clinicians and radiologists must thoroughly look for signs of SATMJ in children with acute mastoiditis to detect this complication, which can lead to disabling and hard-to-treat TMJ ankylosis.

The purpose of this prospective randomized controlled clinical trial was to evaluate the effect of oral administration of bromelain on discomfort after mandibular third molar surgery. Eighty-four consecutive patients requiring surgical removal of a single mandibular impacted third molar under local anesthesia were randomly assigned to receiving no drug (control group, Group A), postoperative 40 mg bromelain every 6 hours for 6 days (Group B), preoperative 4 mg dexamethasone sodium phosphate as a submucosal injection (Group C), and preoperative 4 mg dexamethasone sodium phosphate as a submucosal injection plus postoperative 40 mg bromelain every 6 hours for 6 days (Group D). Standardized surgical and analgesic protocols were adopted. Maximum interincisal distance and facial contours were measured at baseline and on postoperative days 2 and 7. Pain was measured objectively by counting the number of analgesic tablets required. Patient perception of the severity of symptoms was assessed with a follow-up questionnaire (PoSSe scale). On postoperative day 2, there was a statistically significant reduction in facial edema in both Groups C and D compared with the control group, but no statistically significant differences were observed between Group B and the control group. At evaluation on postoperative day 7, Group D showed a statistically significant reduction in postoperative swelling compared with the control group. The combined use of bromelain and dexamethasone (Group D) induced a statistically significant reduction in the total number of analgesic tablets taken after surgery compared with the control group. The treatment groups had a limited, nonsignificant effect on trismus when compared with the control group. Bromelain used singly showed moderate anti-inflammatory efficacy, reducing postoperative swelling, albeit not to any significant extent compared with no drug administration. The combined use of bromelain and dexamethasone sodium phosphate yielded the best results in terms of control of postoperative discomfort.

WE-E-BRE-09: Investigation of the Association Between Radiation-Induced Pain and Radiation Dose in Head and Neck Cancer Patients

DOE Office of Scientific and Technical Information (OSTI.GOV)

Gay, H; Dyk, P; Mullen, D

Purpose: Patients with head and neck cancer who undergo radiotherapy often experience several undesirable side-effects, including xerostomia, trismus, and pain in the head and neck area, but little is know about the dose-volume predictors of such pain. We investigated the association between radiation dose and both throat and esophagus pain during radiotherapy. Methods: We analyzed 124 head and neck patients who received radiotherapy at the Washington University School of Medicine in Saint Louis. For these patients, weekly PROs were recorded, including 16 pain and anatomical location questions. In addition, 17 observational symptoms were recorded. Patients were asked to describe theirmore » pain at each site according to a four-level scale: none (0), mild (1), moderate (2), and severe (3). We explored the association between throat pain and the mean dose received in oral cavity and between esophageal pain and the mean dose received in the esophagus. The severity of pain was determined by the difference between the baseline (week 1) pain score and the maximum pain score during treatment. The baseline pain score was defined as the first available pain score before receiving 10 Gy because radiotherapy pain originates later during treatment. Dose-volume metrics were extracted from treatment plans using CERR. To evaluate the correlation between pain and radiation dose, Spearman's correlation coefficient (Rs) was used. Results: The associations between throat pain and the mean dose to the oral cavity, and between esophagus pain and the mean dose to the esophagus, were both statistically significant, with Rs=0.320 (p=0.003) and Rs=0.424 (p<0.0001), respectively. Mean dose, for each structure, was a better predictor of pain than total integral dose. Conclusion: We demonstrated that pain during radiotherapy in head and neck patients highly correlates with the dose delivered. We will further investigate the association between other pain locations and relevant normal tissue dose characteristics.« less

The study aimed to assess the usefulness of skull base surgery for large juvenile nasopharyngeal angiofibroma (JNA) with lateral extension to the infratemporal fossa. Eleven cases were enrolled for this study, and the mean age was 17.7 years old (range: 8-32). Six out of 11 cases underwent surgery as an initial treatment, and the other five underwent secondary surgery after initial surgery or radiotherapy in other institutions. The range of extension of tumor, feeding arteries, surgical approach, and treatment outcome were estimated. All tumors originated from the sphenopalatine foramen. Based on the imaging study, there was extension to the cavernous sinus observed in eight cases, as well as to the middle cranial fossa (8), orbit (4), and anterior cranial fossa (1). These tumors were diagnosed as Andrews' Stage IVa (3) and IVb (8). However, infiltration into the cavernous sinus was observed in one case only during surgery. Ten tumors were separated carefully from the cavernous sinus or dura and were accurately diagnosed as Stage IIIb. In all cases, the main arterial feeders of the JNAs were branches of the external carotid artery, which were embolized prior to surgery. However, 10 cases were also fed by branches of the internal carotid artery (branches of the ophthalmic artery), in which these arteries could not be embolized. Coronal skin incision (1) and a facial dismasking flap (9) were used, and in one case, wide lateral skin incision with temporary incision of the facial nerve was applied. The orbito-zygomatic approach and its modification was applied to all the cases. Fronto-lateral craniotomy was applied in four cases and lateral craniotomy in seven cases. Total resection was achieved in 10 cases and subtotal resection in one case. No mortality was noted in this series. Temporal trismus was observed in all cases which subsided gradually. Cheek numbness and facial palsy were observed in three and two cases, respectively. Coupled with craniotomy, tumor removal was successfully carried out in 11 patients with JNAs, which showed large lateral extension. Our surgical strategy is a safe and effective approach for the removal of JNAs with infratemporal fossa extension. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Thirty one children (70.5%) and 24 adults (27.9%) had a history of antibiotics abuse. In children group, the site most commonly involved was the parapharyngeal space (18 patients, 40.9%). In adults group, the site most commonly involved was multispace (30 patients, 34.9%). In children group, the most common cause was branchial cleft cyst (5 patients, 11.4%) and the cause remained unknown in 31 patients (70.5%). In adults group, the most common cause was pharyngeal infection (19 patients, 22.2%). All of the 27 patients with associated disease comorbidity were adults and 17 were diabetes mellitus (DM). Streptococcus viridans was the most common pathogen in both children and adults groups. Eighty six (66.2%) underwent surgical drainage and complications were found in 31 patients (4 children, 27 adults).Deep neck infection in adults is easier to have multispace involvement and lead to complications and appears to be more serious than that in children. Understanding the different characteristics between the children and adults with deep neck infection may be helpful in accurate evaluation and proper management.

Video laryngoscopy has been shown to improve glottic exposure when compared to direct laryngoscopy in operating room studies. However, its utility in the hands of emergency physicians (EPs) remains undefined. A simulated difficult airway was used to determine if intubation by EPs using a video Macintosh system resulted in an improved glottic view, was easier, was faster, or was more successful than conventional direct laryngoscopy. Emergency medicine (EM) residents and attending physicians at two academic institutions performed endotracheal intubation in one normal and two identical difficult airway scenarios. With the difficult scenarios, the participants used video laryngoscopy during the second case. Intubations were performed on a medium-fidelity human simulator. The difficult scenario was created by limiting cervical spine mobility and inducing trismus. The primary outcome was the proportion of direct versus video intubations with a grade I or II Cormack-Lehane glottic view. Ease of intubation (self-reported via 10-cm visual analog scale [VAS]), time to intubation, and success rate were also recorded. Descriptive statistics as well as medians with interquartile ranges (IQRs) are reported where appropriate. The Wilcoxon matched pairs signed-rank test was used for comparison testing of nonparametric data. Participants (n = 39) were residents (59%) and faculty. All had human intubation experience; 51% reported more than 100 prior intubations. On difficult laryngoscopy, a Cormack-Lehane grade I or II view was obtained in 20 (51%) direct laryngoscopies versus 38 (97%) of the video-assisted laryngoscopies (p < 0.01). The median VAS score for difficult airways was 50 mm (IQR = 28–73 mm) for direct versus 18 mm (IQR = 9–50 mm) for video (p < 0.01). The median time to intubation in difficult airways was 25 seconds (IQR = 16–44 seconds) for direct versus 20 seconds (IQR = 12–35 seconds) for video laryngoscopy (p < 0.01). All intubations were successful without need for an invasive airway. In this simulation, video laryngoscopy was associated with improved glottic exposure, was perceived as easier, and was slightly faster than conventional direct laryngoscopy in a simulated difficult airway. Absence of secretions and blood limits the generalizability of our findings; human studies are needed.

Purpose There is a large body of evidence supporting the efficacy of low-level laser therapy (LLLT), more recently termed photobiomodulation (PBM) for the management of oral mucositis (OM) in patients undergoing radiotherapy for head and neck cancer (HNC). Recent advances in PBM technology, together with a better understanding of mechanisms involved and dosimetric parameters may lead to the management of a broader range of complications associated with HNC treatment. This could enhance patient adherence to cancer therapy, and improve quality of life and treatment outcomes. The mechanisms of action, dosimetric, and safety considerations for PBM have been reviewed in part 1. Part 2 discusses the head and neck treatment side effects for which PBM may prove to be effective. In addition, PBM parameters for each of these complications are suggested and future research directions are discussed. Methods Narrative review and presentation of PBM parameters are based on current evidence and expert opinion. Results PBM may have potential applications in the management of a broad range of side effects of (chemo)radiation therapy (CRT) in patients being treated for HNC. For OM management, optimal PBM parameters identified were as follows: wavelength, typically between 633 and 685 nm or 780–830 nm; energy density, laser or light-emitting diode (LED) output between 10 and 150 mW; dose, 2–3 J (J/cm2), and no more than 6 J/cm2 on the tissue surface treated; treatment schedule, two to three times a week up to daily; emission type, pulsed (<100 Hz); and route of delivery, intraorally and/or transcutaneously. To facilitate further studies, we propose potentially effective PBM parameters for prophylactic and therapeutic use in supportive care for dermatitis, dysphagia, dry mouth, dysgeusia, trismus, necrosis, lymphedema, and voice/speech alterations. Conclusion PBM may have a role in supportive care for a broad range of complications associated with the treatment of HNC with CRT. The suggested PBM irradiation and dosimetric parameters, which are potentially effective for these complications, are intended to provide guidance for well-designed future studies. It is imperative that such studies include elucidating the effects of PBM on oncology treatment outcomes. PMID:26984249

There is a large body of evidence supporting the efficacy of low-level laser therapy (LLLT), more recently termed photobiomodulation (PBM) for the management of oral mucositis (OM) in patients undergoing radiotherapy for head and neck cancer (HNC). Recent advances in PBM technology, together with a better understanding of mechanisms involved and dosimetric parameters may lead to the management of a broader range of complications associated with HNC treatment. This could enhance patient adherence to cancer therapy, and improve quality of life and treatment outcomes. The mechanisms of action, dosimetric, and safety considerations for PBM have been reviewed in part 1. Part 2 discusses the head and neck treatment side effects for which PBM may prove to be effective. In addition, PBM parameters for each of these complications are suggested and future research directions are discussed. Narrative review and presentation of PBM parameters are based on current evidence and expert opinion. PBM may have potential applications in the management of a broad range of side effects of (chemo)radiation therapy (CRT) in patients being treated for HNC. For OM management, optimal PBM parameters identified were as follows: wavelength, typically between 633 and 685 nm or 780-830 nm; energy density, laser or light-emitting diode (LED) output between 10 and 150 mW; dose, 2-3 J (J/cm(2)), and no more than 6 J/cm(2) on the tissue surface treated; treatment schedule, two to three times a week up to daily; emission type, pulsed (<100 Hz); and route of delivery, intraorally and/or transcutaneously. To facilitate further studies, we propose potentially effective PBM parameters for prophylactic and therapeutic use in supportive care for dermatitis, dysphagia, dry mouth, dysgeusia, trismus, necrosis, lymphedema, and voice/speech alterations. PBM may have a role in supportive care for a broad range of complications associated with the treatment of HNC with CRT. The suggested PBM irradiation and dosimetric parameters, which are potentially effective for these complications, are intended to provide guidance for well-designed future studies.

The transcription repressor FOXP2 is a crucial player in nervous system evolution and development of humans and songbirds. In order to provide an additional insight into its functional role we compared target gene expression levels between human neuroblastoma cells (SH-SY5Y) stably overexpressing FOXP2 cDNA of either humans or the common chimpanzee, Rhesus monkey, and marmoset, respectively. RNA-seq led to identification of 27 genes with differential regulation under the control of human FOXP2, which were previously reported to have FOXP2-driven and/or songbird song-related expression regulation. RT-qPCR and Western blotting indicated differential regulation of additional 13 new target genes in response to overexpression of human FOXP2. These genes may be directly regulated by FOXP2 considering numerous matches of established FOXP2-binding motifs as well as publicly available FOXP2-ChIP-seq reads within their putative promoters. Ontology analysis of the new and reproduced targets, along with their interactors in a network, revealed an enrichment of terms relating to cellular signaling and communication, metabolism and catabolism, cellular migration and differentiation, and expression regulation. Notably, terms including the words “neuron” or “axonogenesis” were also enriched. Complementary literature screening uncovered many connections to human developmental (autism spectrum disease, schizophrenia, Down syndrome, agenesis of corpus callosum, trismus-pseudocamptodactyly, ankyloglossia, facial dysmorphology) and neurodegenerative diseases and disorders (Alzheimer’s, Parkinson’s, and Huntington’s diseases, Lewy body dementia, amyotrophic lateral sclerosis). Links to deafness and dyslexia were detected, too. Such relations existed for single proteins (e.g., DCDC2, NURR1, PHOX2B, MYH8, and MYH13) and groups of proteins which conjointly function in mRNA processing, ribosomal recruitment, cell–cell adhesion (e.g., CDH4), cytoskeleton organization, neuro-inflammation, and processing of amyloid precursor protein. Conspicuously, many links pointed to an involvement of the FOXP2-driven network in JAK/STAT signaling and the regulation of the ezrin–radixin–moesin complex. Altogether, the applied phylogenetic perspective substantiated FOXP2’s importance for nervous system development, maintenance, and functioning. However, the study also disclosed new regulatory pathways that might prove to be useful for understanding the molecular background of the aforementioned developmental disorders and neurodegenerative diseases.

To review the outcome of head-and-neck cancer patients re-irradiated using conformal radiation. From 1983 to 1999, 60 patients with recurrent or new primary head-and-neck cancer received re-irradiation at the University of Michigan. Twenty patients were excluded due to the planned cumulative radiation dose being less than 100 Gy (18) and absence of prior radiation details (2), leaving 40 patients. Thirty-five patients were re-irradiated for unresectable disease, while 4 patients received adjuvant re-irradiation for high-risk disease. Thirty-eight patients had recurrences from previously treated cancer (19 regional, 14 local, 5 regional and local), and 2 patients had new primary tumors. The median time from the first course of radiation to re-irradiation was 21 months. Thirty-one patients (78%) were re-irradiated with curative intent, whereas 9 were treated with palliative intent. Re-irradiation was delivered using conformal techniques in the majority of patients and with concurrent chemotherapy in 14 patients. The median re-irradiation dose was 60 Gy. The median cumulative dose received was 121 Gy. Five patients (13%) did not complete their prescribed course of re-irradiation. The median survival following completion of re-irradiation was 12.5 months. The 1- and 2-year actuarial survival rates were 51.1% and 32.6%, respectively. On multivariate analysis, palliative intent of treatment, tumor bulk, and tumor site other than nasopharynx or larynx were associated with worse survival. The patients treated for unresectable disease did no worse than those treated adjuvantly. The median times to relapse-free survival, local-regional recurrence (LRR)-free survival, and ultimate LRR-free survival (allowing for surgical salvage) were 3.9 months, 7.8 months, and 8.7 months, respectively. Seven patients (18%) are presently alive with no evidence of disease, with a median follow-up of 49.9 months (range 3.3-78.9). Severe radiation-induced complications were seen in 7 patients (18%). Two other patients developed orocutaneous fistulas in the presence of tumor recurrence. Moderate fibrosis and trismus were common. Despite the use of conformal techniques, the prognosis of patients treated with re-irradiation is poor, and complications are not infrequent. A subset of patients is salvageable, and high-dose re-irradiation should be considered in selected patients.

A comfortable postoperative return to daily activities has increased the need to control inflammation after third molar surgery. Anti-inflammatory drugs and analgesics are not exempt from adverse effects such as allergies and chronic gastritis, and they are not without cost. The association between low-level laser and auricular acupuncture can be an alternative when conventional drugs are contraindicated. Among its advantages, we can mention the low risk of side effects, low cost and simplicity of application. The objective of this study is to evaluate the efficiency of low-level laser at auriculotherapy points in reducing postoperative pain in lower third molar surgery. Ninety bilateral, symmetrical lower third molar surgeries will be performed in 45 healthy patients. Each patient will be their own control, through a split-mouth crossover study. One side of the mouth will be randomly chosen and, immediately after surgery, will be treated with low-level laser. After 21 days, the contralateral side will be operated on with low-level laser simulation used postoperatively. This regimen (laser application or not) will be repeated at 24 and 48 h after surgery. All patients will be requested to take analgesics (acetaminophen) if they have pain, i.e. in case of pain. Neither the surgeon nor the patients will know the assigned treatment. The primary variable will be postoperative pain assessed using a Visual Analog Scale, and the secondary variables will be trismus, edema, local temperature, dysphagia, presence of infection and painkiller ingestion. These variables will be assessed at baseline, 24 h, 48 h and 7 days after surgery. Blood samples for systemic inflammatory cytokine (TNF-α, IL-1, IL-6 and IL-8) analysis will be assessed at baseline and 24 h after surgery. Some authors believe that using a wavelength of 633 to 670 nm is a good option for laser therapy in the field of acupuncture. This wavelength can penetrate biological tissue to a depth of about 3 mm. However, for auriculotherapy points, the stimulus (mustard seeds, needles 1 to 2.5 mm) does not penetrate so deeply. For this reason, we chose a laser wavelength of 660 nm (red wavelength).

It is estimated that more than 90% of head and neck cancer (HNC) survivors who underwent chemoradiotherapy experience one or more nutrition impact symptoms (NIS) in the months or years thereafter. Despite the high prevalence, there is limited research addressing long-term impact of NIS on outcomes such as nutrition and quality of life in HNC survivors treated with chemoradiotherapy. To conduct a systematic review of the literature pertaining to the presence of nutrition impact symptoms and their associated outcomes in post-chemoradiotherapy head and neck cancer survivors. A systematic review was conducted across three databases according to PRISMA guidelines and used to identify current literature regarding NIS in HNC survivors. A keyword search was conducted in PubMed, Scopus, and Web of Science from 2007 to 2017. Studies that met all of the following criteria were included in the review: (1) studies must include human subjects with a HNC diagnosis; (2) study participants must have received chemoradiotherapy; (3) study participants must have been post-treatment for a minimum of 3 months at the time of data collection; (4) full-text articles must have appeared in peer-reviewed journals; (5) papers must have been published in English; (6) studies must be quantitative in nature; (7) studies must have reported at least one NIS; and (8) studies must address at least one of the following outcomes: nutrition, functional status, or quality of life. Two independent reviewers assessed study quality using a predefined set of criteria. A systematic search yielded 1119 papers, of which 15 met the inclusion criteria. The study reviewed existing evidence of NIS in a variety of HNC survivors ranging from 3 months to greater than 10 years post-chemoradiotherapy treatment. Eight hundred forty-nine study participants were included in the review. Of the 15 studies, 10 were designed as prospective cohort studies, 4 were cross-sectional studies, and 1 was a retrospective cohort study. Functional impairments as a result of chemoradiotherapy to the head and neck are prevalent in research and include dysphagia, xerostomia, trismus, salivary issues, mucositis, and oral pain. NIS negatively influence HNC survivors beyond the acute phase of treatment. These symptoms are associated with decreased nutrition and quality of life. Interventions are necessary to improve survivors' eating challenges beyond the completion of treatment. If practitioners do not follow patients long term, patients may suffer consequences of NIS including malnutrition risk, weight loss, and decreased food intake and quality of life. The prevalence and consequences of nutrition impact symptoms are substantial among head and neck cancer survivors beyond the acute phase of cancer treatment. Oncology clinicians should continuously monitor and manage these symptoms throughout the cancer continuum.

The most frequent indications for tooth extractions are dental caries and periodontal infections, and these extractions are generally done by general dental practitioners. Antibiotics may be prescribed to patients undergoing extractions to prevent complications due to infection. To determine the effect of antibiotic prophylaxis on the development of infectious complications following tooth extractions. The following electronic databases were searched: the Cochrane Oral Health Group's Trials Register (to 25 January 2012), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 1), MEDLINE via OVID (1948 to 25 January 2012), EMBASE via OVID (1980 to 25 January 2012) and LILACS via BIREME (1982 to 25 January 2012). There were no restrictions regarding language or date of publication. We included randomised double-blind placebo-controlled trials of antibiotic prophylaxis in patients undergoing tooth extraction(s) for any indication. Two review authors independently assessed risk of bias for the included studies and extracted data. We contacted trial authors for further details where these were unclear. For dichotomous outcomes we calculated risk ratios (RR) and 95% confidence intervals (CI) using random-effects models. For continuous outcomes we used mean differences (MD) with 95% CI using random-effects models. We examined potential sources of heterogeneity. The quality of the body of evidence has been assessed using the GRADE tool. This review included 18 double-blind placebo-controlled trials with a total of 2456 participants. Five trials were assessed at unclear risk of bias, thirteen at high risk, and none at low risk of bias. Compared to placebo, antibiotics probably reduce the risk of infection in patients undergoing third molar extraction(s) by approximately 70% (RR 0.29 (95% CI 0.16 to 0.50) P < 0.0001, 1523 participants, moderate quality evidence) which means that 12 people (range 10-17) need to be treated with antibiotics to prevent one infection following extraction of impacted wisdom teeth. There is evidence that antibiotics may reduce the risk of dry socket by 38% (RR 0.62 (95% CI 0.41 to 0.95) P = 0.03, 1429 participants, moderate quality evidence) which means that 38 people (range 24-250) need to take antibiotics to prevent one case of dry socket following extraction of impacted wisdom teeth. There is also some evidence that patients who have prophylactic antibiotics may have less pain (MD -8.17 (95% CI -11.90 to -4.45) P < 0.0001, 372 participants, moderate quality evidence ) overall 7 days after the extraction compared to those receiving placebo, which may be a direct result of the lower risk of infection. There is no evidence of a difference between antibiotics and placebo in the outcomes of fever (RR 0.34, 95% CI 0.06 to 1.99), swelling (RR 0.92, 95% CI 0.65 to 1.30) or trismus (RR 0.84, 95% CI 0.42 to 1.71) 7 days after tooth extraction.Antibiotics are associated with an increase in generally mild and transient adverse effects compared to placebo (RR 1.98 (95% CI 1.10 to 3.59) P = 0.02) which means that for every 21 people (range 8-200) who receive antibiotics, an adverse effect is likely. Although general dentists perform dental extractions because of severe dental caries or periodontal infection, there were no trials identified which evaluated the role of antibiotic prophylaxis in this group of patients in this setting. All of the trials included in this review included healthy patients undergoing extraction of impacted third molars, often performed by oral surgeons. There is evidence that prophylactic antibiotics reduce the risk of infection, dry socket and pain following third molar extraction and result in an increase in mild and transient adverse effects. It is unclear whether the evidence in this review is generalisable to those with concomitant illnesses or immunodeficiency, or those undergoing the extraction of teeth due to severe caries or periodontitis. However, patients at a higher risk of infection are more likely to benefit from prophylactic antibiotics, because infections in this group are likely to be more frequent, associated with complications and be more difficult to treat. Due to the increasing prevalence of bacteria which are resistant to treatment by currently available antibiotics, clinicians should consider carefully whether treating 12 healthy patients with antibiotics to prevent one infection is likely to do more harm than good.
