ABSTRACT
INTRODUCTION: Patient engagement and integrated knowledge translation (iKT) processes improve health outcomes and care experiences through meaningful partnerships in consensus-building initiatives and research. Consensus-building is essential for engaging a diverse group of experienced knowledge users in co-developing and supporting a solution where none readily exists or is less optimal. Patients and caregivers provide invaluable insights for building consensus in decision-making around healthcare, policy and research. However, despite emerging evidence, patient engagement remains sparse within consensus-building initiatives. Specifically, our research has identified a lack of opportunity for youth living with chronic health conditions and their caregivers to participate in developing consensus on indicators/benchmarks for transition into adult care. To bridge this gap and inform our consensus-building approach with youth/caregivers, this scoping review will synthesise the extent of the literature on patient and other knowledge user engagement in consensus-building healthcare initiatives. METHODS AND ANALYSIS: Following the scoping review methodology from Joanna Briggs Institute, published literature will be searched in MEDLINE, EMBASE, CINAHL and PsycINFO databases from inception to July 2023. Grey literature will be hand-searched. Two independent reviewers will determine the eligibility of articles in a two-stage process, with disagreements resolved by a third reviewer. Included studies must be consensus-building studies within the healthcare context that involve patient engagement strategies. Data from eligible studies will be extracted and charted on a standardised form. Abstracted data will be analysed quantitatively and descriptively, according to specific consensus methodologies, and patient engagement models and/or strategies. ETHICS AND DISSEMINATION: Ethics approval is not required for this scoping review protocol. The review process and findings will be shared with and informed by relevant knowledge users. Dissemination of findings will also include peer-reviewed publications and conference presentations. The results will offer new insights for supporting patient engagement in consensus-building healthcare initiatives. PROTOCOL REGISTRATION: https://osf.io/beqjr.

There is a growing number of youth with healthcare needs such as disabilities or chronic health conditions who require lifelong care. In Canada, transfer to the adult healthcare system typically occurs at age 18 and is set by policy regardless of whether youth and their families are ready. When the transition to adult services is suboptimal, youth may experience detrimental gaps in healthcare resulting in increased visits to the emergency department and poor healthcare outcomes. Despite the critical need to support youth with disabilities and their families to transition to the adult healthcare system, there is limited legislation to ensure a successful transfer or to mandate transition preparation in Canada. This advocacy and policy planning work was conducted in partnership with the Patient and Family Advisory Council (PFAC) within the CHILD-BRIGHT READYorNot™ Brain-Based Disabilities (BBD) Project and the CHILD-BRIGHT Policy Hub. Together, we identified the need to synthesize and better understand existing policies about transition from pediatric to adult healthcare, and to recommend solutions to improve healthcare access and equity as Canadian youth with disabilities become adults. In this perspective paper, we will report on a dialogue with key informants and make recommendations for change in healthcare transition policies at the healthcare/community, provincial and/or territorial, and/or national levels.
ABSTRACT
Objective To investigate the incidence and degree of contralateral sinus disease following treatment of sinonasal malignancy (SNM) using radiological findings as an outcome measure. Study Design Retrospective case series. Setting Tertiary referral academic center. Participants Patients with SNM treated with surgical and adjuvant radiotherapy with or without concurrent chemotherapy. Main Outcome Measures Pre- and posttreatment computed tomography and magnetic resonance imaging scans, Lund-Mackay (LM) score, date of diagnosis, chemotherapy, and dosage of radiation therapy (RT). Results There was a significant difference between pre- and posttreatment LM scores ( p < 0.001) of the contralateral paranasal sinuses. There was no statistical significance between the change in pre- and posttreatment LM scores and patient age, gender, chemotherapy, RT dosage, and time lapse between diagnosis and when we performed this study in the univariate and the multivariable analyses. Conclusions Following treatment of SNM with surgical resection and RT, there was a significant increase in incidence and degree of mucosal thickening of the contralateral sinus by LM grading that persisted after the completion of treatment. This indicates the need for long-term follow-up to monitor for chronic rhinosinusitis as a delayed complication following treatment of SNM.
ABSTRACT
Language learners are sensitive to phonotactic patterns from an early age, and can acquire both simple and 2nd-order positional restrictions contingent on segment identity (e.g., /f/ is an onset with /æ/but a coda with /ɪ/). The present study explored the learning of phonototactic patterns conditioned on a suprasegmental cue: lexical stress. Adults first heard non-words in which trochaic and iambic items had different consonant restrictions. In Experiment 1, participants trained with phonotactic patterns involving natural classes of consonants later falsely recognized novel items that were consistent with the training patterns (legal items), demonstrating that they had learned the stress-conditioned phonotactic patterns. However, this was only true for iambic items. In Experiment 2, participants completed a forced-choice test between novel legal and novel illegal items and were again successful only for the iambic items. Experiment 3 demonstrated learning for trochaic items when they were presented alone. Finally, in Experiment 4, in which the training phase was lengthened, participants successfully learned both sets of phonotactic patterns. These experiments provide evidence that learners consider more global phonological properties in the computation of phonotactic patterns, and that learners can acquire multiple sets of patterns simultaneously, even contradictory ones.

OBJECTIVE: To collect data on skull base surgery training experiences and practice patterns of otolaryngologists that recently completed fellowship training. DESIGN: A 24-item survey was disseminated to physicians who completed otolaryngology fellowships in rhinology, head and neck oncology, or neurotology between 2010 and 2014. RESULTS: During a typical year, 50% of rhinologists performed more than 20 endoscopic anterior skull base cases, 83% performed fewer than 20 open cases, and were more confident performing advanced transplanum (p = 0.02) and transclival (p = 0.03) endoscopic approaches than head and neck surgeons. Head and neck surgeons performed fewer than 20 endoscopic and fewer than 20 open cases in 100% of respondents and were more confident with open approaches than rhinologists (p = 0.02). Neurotologists performed more than 20 lateral skull base cases in 45% of respondents during a typical year, fewer than 20 endoscopic ear cases in 95%, and were very comfortable performing lateral skull base approaches. CONCLUSION: Many recent otolaryngology fellowship graduates are integrating skull base surgery into their practices. Respondents reported high confidence levels performing a range of cranial base approaches. Exposure to endoscopic ear techniques is minimal in neurotology training, and rhinology training appears to offer increased exposure to skull base surgery compared with head and neck training.
ABSTRACT
OBJECTIVE: To characterize our experience with the surgical management of anterior skull base malignancy, and to propose an algorithm for surgical approach to anterior skull base malignancies. DESIGN: Retrospective review. SETTING: Academic cranial base center. PARTICIPANTS: Sixty-seven patients who underwent resection of paranasal sinus or anterior skull base malignancy with an endoscopic, cranioendoscopic, or traditional anterior craniofacial approach. OUTCOME MEASURES: Complications, recurrence, and survival. RESULTS: There were 48 males and 19 females, ranging from 6 to 88 years old. There were three groups: endonasal endoscopic resection (n = 10), cranioendoscopic resection (n = 12), and traditional craniofacial resection (n = 45). The most common tumor pathologies included esthesioneuroblastoma, squamous cell carcinoma, and sinonasal undifferentiated carcinoma. Patients with T3/T4 disease were less likely to undergo endoscopic resection (p = 0.007). The 5-year disease-free survival was 82.1% overall, with no statistically significant differences among approaches. There were no differences in orbital complications, meningitis, or cerebrospinal fluid leak. Use of a transfacial incisions predisposed patients to surgical site infection and sinocutaneous fistulae. An algorithm for surgical approach was developed based on these results. CONCLUSION: Sinonasal and skull base malignancies can be safely surgically addressed via several approaches. Surgical approach should be selected algorithmically based on preoperative clinical assessment of the tumor and known postoperative complication rates.
ABSTRACT
OBJECTIVES/HYPOTHESIS: The hypoglossal nerve (XII) has been used as a donor nerve in facial and laryngeal reinnervation. The purpose of this study was to investigate the neuromuscular changes that occur within the tongue following partial or complete transection of XII using a canine model. STUDY DESIGN: Histopathological comparison of tongue denervation following two types of XII resection in a canine model. METHODS: Ten adult canines underwent complete unilateral resection of XII or resection of only the medial terminal branch of the hypoglossal nerve (mXII). After 6 months of recovery, tongue specimens were analyzed histopathologically using whole cross-sections. Routine histologic sections were assessed by two neuropathologists blinded to the type of denervation. The cross-sectional area was calculated of both sides of the tongue, and the amount of myosin was quantified morphometrically using immunohistochemistry for myosin (antimyosin heavy chain, fast isotype). Statistical comparison between partial and complete denervation was performed using the Student t test. RESULTS: Six months following XII transection, quantitative measures of the cross-sectional area of the tongue and content of myosin demonstrated severe muscle atrophy on the operated side of the tongue for both groups, compared to the nonoperated side. For partial transection involving only mXII, the degree of atrophy was less severe (P < .05). CONCLUSIONS: This study provides new histological information demonstrating that partial resection of the hypoglossal nerve, sacrificing only the proximal medial branch of the hypoglossal nerve (mXII), results in less severe atrophy of the tongue than complete transection of the entire hypoglossal nerve. LEVEL OF EVIDENCE: NA Laryngoscope, 126:2689-2693, 2016.

BACKGROUND: Head and neck cancer constitutes a substantial portion of the burden of disease in South Asia, and there is an undersupply of surgical capacity in this region. The purpose of this study was to estimate the economic welfare losses due to head and neck cancer in India, Pakistan, and Bangladesh in 2010. METHODS: We used publicly available estimates of head and neck cancer morbidity and mortality along with a concept termed the value of a statistical life to estimate economic welfare losses in the aforementioned countries in 2010. RESULTS: Economic losses because of head and neck cancer in India, Pakistan, and Bangladesh totaled $16.9 billion (2010 US dollars [USD]), equivalent to 0.26% of the region's economic output. Bangladesh, the poorest country, experienced the greatest proportional losses. CONCLUSION: The economic consequences of head and neck cancer in South Asia are significant, and building surgical capacity is essential to begin to address this burden. © 2016 Wiley Periodicals, Inc.

BACKGROUND: Sphenoid sinus fungal balls (SSFB) are rare entities that can result in serious orbital and intracranial complications. There are few published reports of complications that result from SSFB. OBJECTIVE: To review the incidence of skull base erosion and orbital or intracranial complications in patients who present with SSFB. METHODS: A retrospective review was performed of all the patients with SSFB who were treated at the Massachusetts Eye and Ear Infirmary from 2006 to 2014. Presenting clinical data, radiology, operative reports, pathology, and postoperative course were reviewed. RESULTS: Forty-three patients with SSFB were identified. Demographic data were compared between patients with (39.5%) and those without (61.5%) skull base erosion. Two patients underwent emergent surgery for acute complications of SSFB (one patient with blindness, one patient who had a seizure). Both patients with acute complications had evidence of skull base erosion, whereas no patients with an intact skull base developed an orbital or intracranial complication (p = 0.15). All the patients were surgically managed via an endoscopic approach. CONCLUSION: SSFBs are rare but may cause significant skull base erosion and potentially severe orbital and intracranial complications if not treated appropriately. Endoscopic sphenoidotomy is effective in treating SSFB and should be performed emergently in patients who presented with associated complications.
ABSTRACT
BACKGROUND: Head and neck cancer, for which the diagnosis and treatment are often surgical, comprises a substantial proportion of the burden of disease in South Asia. Further, estimates of surgical volume suggest this region faces a critical shortage of surgical capacity. We aimed to estimate the total economic welfare losses due to the morbidity and mortality of head and neck cancer in India, Pakistan, and Bangladesh for 1 year (2010). METHODS: We used publicly available estimates from the Institute for Health Metrics and Evaluation regarding the morbidity and mortality of head and neck cancer in India, Pakistan, and Bangladesh, along with an economic concept termed the value of a statistical life, to estimate total economic welfare losses due to head and neck cancer in the aforementioned countries in the year 2010. The counterfactual scenario is absence of disease. Sensitivity analyses were done with regard to how the value of a statistical life changes with income. FINDINGS: In 2010, the most conservative estimate of economic welfare losses due to head and neck cancer in the three studied countries is US$16·9 billion (2010 USD, PPP), equivalent to 0·26% of their combined gross domestic product (GDP). The welfare losses experienced by the population younger than 70 years of age accounted for US$15·2 billion (90% of the total losses). When adjusted for the size of their respective economies, Bangladesh, the poorest of the three countries, incurred the greatest loss (US$930 million), equivalent to 0·29% of its GDP. India and Pakistan experienced welfare losses of US$14·1 billion and US$1·9 billion, respectively. These figures are equivalent to 0·26% of the GDP for both countries. Oropharyngeal and hypopharyngeal cancer made up the largest share of the total burden at 39% (US$6·6 billion), followed closely by oral cavity cancer at 34% (US$5·7 billion). INTERPRETATION: The burden of non-communicable diseases, to which cancer contributes greatly, is growing at a rapid pace in South Asia. Head and neck cancer is a leading cause of cancer-related mortality in this region, and this study suggests that the associated economic welfare losses, estimated to be US$16·9 billion in 2010 alone, are substantial. A number of strategies are available to address this burden. Surgery, as part of a multidisciplinary approach that includes radiation therapy and chemotherapy, plays a central part in the diagnosis and treatment of head and neck cancer, and building surgical capacity, which offers large economies of scope and scale, can not only address the burden of head and neck cancer, but also create a platform for beginning to confront the rising tide of non-communicable diseases. FUNDING: None.
ABSTRACT
IMPORTANCE: Patients with a septal deviation and concerns about nasal obstruction often undergo septoplasty to improve nasal airflow. Following primary septoplasty, however, some patients have persistent symptoms due to nasal valve dysfunction and may require nasal valve surgery. OBJECTIVES: To evaluate the change in disease-specific quality of life for patients who undergo nasal valve correction after failed septoplasty using the Nasal Obstruction Symptom Evaluation (NOSE) survey and to determine whether identifiable anatomical risk factors are more common in patients with a history of failed septoplasty. DESIGN, SETTING, AND PARTICIPANTS: Prospective observational outcomes study conducted at a tertiary care medical center. Forty patients who underwent nasal valve correction through an open approach from January 1, 2012, through December 31, 2014, with a history of septoplasty for nasal obstruction were included. Data analysis was conducted from January 1, 2013, through May 1, 2015. [corrected]. INTERVENTIONS: Demographic information, a standardized nasal examination, and preoperative and postoperative NOSE scores were collected and reviewed. MAIN OUTCOMES AND MEASURES: Comparison between preoperative and postoperative NOSE scores at 2, 4, and more than 6 months after surgery. RESULTS: Forty patients were included in the study; 23 (57%) were male and 17 (43%) were female. The mean age was 39.3 years. Findings from preoperative nasal examination demonstrated moderate or severe internal nasal valve narrowing in 38 (95%) patients, internal nasal valve collapse in 19 (48%), external nasal valve narrowing in 18 (45%), or external nasal valve collapse in 16 (40%). The most common anatomical cause of obstruction was internal nasal valve narrowing in 38 (95%) patients, dorsal septum deflection in 26 (65%), and narrowed middle vault in 16 (40%). The mean (SD) preoperative NOSE score was 75.7 (20.1). Mean (SD) postoperative NOSE scores at 2, 4, and greater than 6 months were 31.4 (27.2), 34.0 (19.8), and 22.1 (18.8), respectively, with significantly improved NOSE scores at each time point compared with before surgery (P < .001). CONCLUSIONS AND RELEVANCE: Nasal valve dysfunction remains an underdiagnosed entity and should be considered in all patients with septal deviation before septoplasty, especially in patients with a severe dorsal deflection and a narrow middle vault. In this study, surgical nasal valve correction demonstrated a significant reduction in nasal obstruction, as measured by a validated outcome measure, in patients for whom a previous septoplasty had failed. LEVEL OF EVIDENCE: 4.

IMPORTANCE: Vocal fold immobility following injury to the recurrent laryngeal nerve (RLN) may lead to substantial morbidity. A reinnervation treatment strategy offers several theoretical benefits over static treatment options. This study evaluates the robustness of reinnervation of the larynx using a split-hypoglossal nerve graft in an animal model, with outcomes assessed by independent blinded review. OBJECTIVES: To assess whether a full-hypoglossal nerve graft to the RLN after RLN section can provide return of dynamic vocal fold motion in a canine model, and to validate that a split-hypoglossal nerve graft to the RLN may also provide dynamic vocal fold motion to rehabilitate laryngeal function in a canine model. DESIGN, SETTING, AND SUBJECTS: A pilot animal study to assess the feasibility and morbidity of laryngeal reinnervation following RLN injury with an end-to-end full-hypoglossal or split-hypoglossal nerve graft was performed at an animal care and research facility in 10 adult female dogs. The study dates were January to July 2013. INTERVENTIONS: We performed full-hypoglossal (full XII group [n = 5]) and split-hypoglossal (split XII group [n = 5]) nerve grafts to the RLN in a canine model following RLN section. MAIN OUTCOMES AND MEASURES: Morbidity was evaluated through scored feeding observation. Laryngeal function was assessed by video laryngoscopy and evoked laryngeal electromyography was performed at baseline and 6 months after surgery. Video laryngoscopy was graded by independent reviewers blinded to study intervention. RESULTS: No clinically significant morbidity was identified after surgery. On review of video laryngoscopy, all 5 animals in the full XII group and all 5 animals in the split XII group demonstrated vocal fold motion by at least 1 independent reviewer. All 3 reviewers agreed on motion in 1 of 5 animals in the full XII group and in 1 of 5 animals in the split XII group. Stimulation of the hypoglossal nerve demonstrated neural connection on evoked laryngeal electromyography in all animals at 6 months. CONCLUSIONS AND RELEVANCE: This study confirms that a full-hypoglossal or split-hypoglossal nerve graft may restore vocal fold motion, without significant functional morbidity, following RLN section in a canine model.

Objective To determine trends in sinonasal undifferentiated carcinoma (SNUC) survival patterns in the United States. Design Retrospective review of national database. Participants All cases of SNUC in the National Cancer Institute's Surveillance Epidemiology and End Results program from 1973 to 2010 were examined. Main Outcome Measures Age-adjusted incidence and survival rates were calculated and stratified by demographic information and treatment modality. Cohort analysis was performed to analyze survival patterns over time. Results A total of 318 SNUC cases were identified. Age-adjusted incidence rate (IR) was 0.02 per 100,000. Incidence was greater in males (IR: 0.03) than females (IR: 0.01; p = 0.03). Overall 5- and 10-year relative survival rate was 34.9% and 31.3%, respectively. Overall median survival was 22.1 months. Median survival following surgery combined with radiation was 41.9 months. Five-year relative survival rate following surgery, radiation, or surgery combined with radiation was 38.7%, 36.0%, and 39.1%, respectively. Median survival from 1973-1986 and 1987-2010 was 14.5 and 23.5 months, respectively. Conclusions This study provides new data regarding survival patterns of SNUC in the United States, confirming survival benefit with surgery and radiation as well as identifying a trend toward improved survival in recent decades.
ABSTRACT
OBJECTIVE: To characterize patterns of utilization and outcomes following transfusion in head and neck patients undergoing free flap reconstruction. STUDY DESIGN: Case series with chart review. SETTING: Tertiary academic medical center. SUBJECTS AND METHODS: Two hundred eighty-two head and neck patients undergoing free flap reconstruction from 2011 to 2013. Outcome parameters included post-transfusion hematocrit increase, length of stay (LOS), flap survival, and perioperative complications. RESULTS: Of all head and neck free flap patients, 48.9% received blood transfusions. Average pretransfusion hametocrit (Hct) was 24.7%±0.2% with 2.5±0.1 units of blood transfused. Transfused patients were more likely to have been taken back to the operating room. Rates of transfusion were similar between flap types, although anterolateral thigh (ALT) and fibular free flap (FFF) patients had higher transfusion requirements compared to radial forearm free flap (RFFF) patients. Further, FFF patients trended toward receiving transfusions earlier. Transfusion did not influence flap survival but was associated with wound dehiscence, myocardial infarction, congestive heart failure, respiratory distress, and pneumonia. Subset analyses by flap type revealed that differences were significant among the RFFF and FFF cohorts but not ALT patients. When comparing patients who were transfused for Hct<21 to those transfused for Hct<27, there were no differences in LOS, flap survival, or postsurgical complications. CONCLUSIONS: Among the different types of flaps, FFF and ALT are associated with higher transfusion requirements. Transfusion in patients undergoing free flap reconstruction does not significantly affect flap survival but was associated with perioperative complications. Our data support consideration of a restrictive transfusion policy in free flap patients.

BACKGROUND: Intra-operative nerve monitoring (IONM) of the recurrent laryngeal nerve (RLN) during thyroid and parathyroid surgery is thought to aid in identification and dissection of the RLN. While utilization of IONM is increasing, one area of variability in its application is the assessment of adequate endotracheal tube electrode placement for IONM during the case. The main objective of this study is to assess the overall success of utilizing respiratory variation to confirm proper endotracheal tube placement for RLN monitoring. METHODS: A prospective study of RLN monitoring during thyroid and parathyroid surgery at an academic referral center. RESULTS: Fifty-five cases were included. Fifty (91 %) achieved optimal respiratory variation during endotracheal tube position. Five (9 %) required repeat laryngoscopy to confirm correct endotracheal tube placement following patient positioning. For the respiratory variation group, average amplitude achieved during initial vagus, maximum vagus, initial RLN, and maximal RLN was 700 (± 474) mA, 921 (± 616) mA, 887 (± 584) mA, and 1330 (± 843) mA during evoked stimulation, respectively. For the repeat laryngoscopy group, average amplitude achieved during initial vagus, maximum vagus, initial RLN, and maximal RLN evoked stimulation was 591 (± 364) mA, 959 (± 306) mA, 771 (± 424) mA, and 1462 (± 855) mA during evoked stimulation, respectively. There was no statistical difference between the two groups for average initial vagus amplitude (p = 0.62), average maximum vagus amplitude (p = 0.89), average initial RLN amplitude (p = 0.67), or average maximum RLN amplitude (p = 0.74). CONCLUSION: The findings of this study support the International Neural Monitoring Study Group recommendation that confirmation of endotracheal tube electrode placement be performed either by confirmation of adequate respiratory variation or by repeat direct laryngoscopy.

OBJECTIVES/HYPOTHESIS: To determine the value of a collaborative course for advanced head and neck surgery in East Africa. STUDY DESIGN: Survey of participants. METHODS: A 3-day course in head and neck surgery was designed for otolaryngologists and trainees from Kenya and surrounding countries through a collaborative effort between Kenyatta National Hospital, the University of Nairobi, and the Head and Neck Divisions from the Vanderbilt Bill Wilkerson Center and the Massachusetts Eye and Ear Infirmary. Topics included neck dissection, parotidectomy, total laryngectomy, parapharyngeal space tumors excision, and pectoralis myocutaneous flaps. A pre- and postcourse self-evaluation survey was administered to measure course impact. RESULTS: Eighteen otolaryngologists and trainees participated in the course, with 17 completing course surveys. The majority of participants (72%) were from Kenya. Prior to the start of the course, 41%, 71%, 23%, 12%, and 0% of participants indicated they could complete a neck dissection, parotidectomy, parapharyngeal space mass excision, total laryngectomy, and pectoralis myocutaneous flap, respectively. Following the course, 50%, 94%, 69%, 25%, and 38% of participants indicated they could complete a neck dissection, parotidectomy, total laryngectomy, parapharyngeal space tumors excision, respectively, with a statistically significant increase identified for pectoralis myocutaneous flaps (P < .001) and total laryngectomy (P = .009). There was also a trend toward an increase in the number of participants indicating an ability to complete parotidectomy following the course (P = .085). CONCLUSIONS: This survey demonstrates the potential value of a collaborative course in advanced head and neck surgery as one useful model for increasing the number of well-trained head and neck surgeons in East Africa.

OBJECTIVES/HYPOTHESIS: Determine trends in global health-related publication in otolaryngology. STUDY DESIGN: A review of research databases. METHODS: A search of publications available on PubMed and nine additional databases was undertaken reviewing two time periods 10 years apart for the timeframes 1998 to 2002 (early time period) and 2008 to 2012 (recent time period) using specific search terms to identify global health-related publications in otolaryngology. Publications were examined for region of origin, subspecialty, type of publication, and evidence of international collaboration. χ and t test analyses were used to identify trends. RESULTS: In the 1998 to 2002 time period, a total of 26 publications met inclusion criteria for the study, with a mean of 5.2 ± 2.8 publications per year. In the 2008 to 2012 time period, a total of 61 publications met inclusion criteria, with a mean of 12.3 ± 5.6 publications per year. The 235% increase in global health-related publications identified between the two study periods was statistically significant (P = .02). The absolute number of publications in which collaboration occurred between countries increased from three in the early time period to nine the recent time period. CONCLUSIONS: There has been a significant increase in the volume of global health-related publications in English language otolaryngology journals over the past decade, providing strong evidence of the increasing trend of global health as an academic pursuit within the field of otolaryngology.

OBJECTIVES/HYPOTHESIS: To identify histopathologic features associated with poor correlation of frozen and permanent pathology margins following wide local excision for advanced cutaneous squamous cell carcinomas of the head and neck. STUDY DESIGN: Retrospective review. METHODS: A retrospective review of patients undergoing excision of advanced head and neck squamous cell carcinomas between the years 2010 AND 2013 was performed. Demographic, operative, and pathology data were collected. Overall correlation between frozen section margins and final margins on permanent section results was calculated. Positive and negative predictive values of several histopathologic features were determined. RESULTS: Forty-one cases were identified from the database. Perineural invasion, lymphovascular invasion, and a component of poorly differentiated carcinoma were identified in 61.3%, 34.5%, and 17.1% of cases, respectively. Discrepancy between frozen section margins and permanent margins was identified in eight cases (19.5%). The false-negative rate for poorly differentiated carcinoma, lymphovascular invasion, and perineural invasion was 14%, 36%, 26%, respectively. The positive and negative predictive value of poorly differentiated carcinoma, lymphovascular invasion, and perineural invasion in predicting discrepancy between frozen and permanent margins was 14% and 80%, 36% and 84%, and 26% and 92%, respectively. CONCLUSIONS: This study demonstrated a moderate rate of discrepancy between frozen and permanent section analysis of operative margins from high-risk cutaneous squamous cell carcinomas of the head and neck. The presence or absence of certain histopathologic features appears to be associated with a higher rate of frozen section discrepancy. Evaluation of these features in a preoperative biopsy or staging excision may be useful in planning definitive excision and reconstruction.

Internal carotid artery injury is a rare and devastating complication of endoscopic sinus and skull base surgery that has an associated mortality rate of 15%. This case describes a patient who developed massive epistaxis following routine sinus surgery and was eventually diagnosed with a pseudoaneurysm of the cavernous internal carotid artery. Endovascular coiling and Onyx (Covidien, Irvine, California, United States) liquid embolization were ultimately used to completely occlude the internal carotid artery with resolution of bleeding; however, the patient had an unexpected late complication of coil extrusion through the pseudoaneurysm sac into the sphenoid sinus and nasal cavity. The endoscopic skull base team safely excised the coils endoscopically without recurrent bleeding. We describe the multidisciplinary operative management of this case of endovascular coil extrusion to increase awareness of this potentially life-threatening complication.
ABSTRACT
Objectives To update the Massachusetts General Hospital (MGH) and Massachusetts Eye and Ear Infirmary (MEEI) experience in the management of esthesioneuroblastoma (ENB) with multimodality therapy and to reassess treatment outcomes and complications in a larger cohort with longer follow-up times. Design A retrospective chart review. Setting A tertiary referral center. Participants All patients presenting with ENB and managed at the MGH and MEEI from 1997 to 2013. Main Outcome Measures Disease-free and overall survival. Results Twenty-two patients were identified with an average follow-up of 73 months. Ten patients presented with Kadish stage B disease and 12 with stage C disease. A total of six patients (27%) developed regional metastases. Treatment for all patients included craniofacial resection (CFR) followed by proton beam irradiation with or without chemotherapy. The 5-year disease-free and overall survival rates were 86.4% and 95.2%, respectively, by Kaplan-Meier analysis. Negative margins were a significant factor in disease-free survival. One patient experienced severe late-radiation toxicity. Conclusions ENB is safely and effectively treated with CFR followed by proton beam irradiation. The high incidence of regional metastases warrants strong consideration for elective neck irradiation. Proton beam radiation is associated with lower rates of severe late-radiation toxicity than conventional radiotherapy.
