Objective The purpose of this study was to evaluate the quality of evidence of rhinology and rhinologic skull base surgery (RSBS) research and its evolution over the past decade. Study Design Review article. Setting We reviewed articles from 2007 to 2019 in 4 leading peer-reviewed otolaryngology journals and 3 rhinology-specific journals. Methods The articles were reviewed and levels of evidence were assigned using the Oxford Centre for Evidence-Based Medicine 2011 guidelines. High quality was defined as level of evidence 1 or 2. Results In total, 1835 articles were reviewed in this study spanning a 13-year period. Overall, the absolute number of RSBS publications increased significantly 22.6% per year, from 108 articles in 2007 to 481 in 2019 (P < .001; 95% CI, 7.9-37.2). In 2007, only 13 articles, or 15%, were high quality, and this grew to 146 articles, or 39%, in 2019. A 14.0% per year exponential increase in the number of high-quality publications was found to be statistically significant (P < .001; 95% CI, 7.2, 20.7). Overall, high-quality publications represented just 25.8% of RSBS articles overall. There was no significant difference in quality between rhinology-specific journals and general otolaryngology journals (χ2 = 3.1, P = .077). Conclusion The number of overall publications and of high-quality RSBS publications has significantly increased over the past decade. However, the proportion of high-quality studies continues to represent a minority of total RSBS research.

BACKGROUND Neoadjuvant chemotherapy followed by surgery (NAC + S), a paradigm based on systemic escalation coupled with surgery-based de-escalation, is under investigation for treatment of HPV-associated oropharynx cancer (OPC). METHODS Prospective cohort of patients with non-metastatic, p16 positive OPC enrolled in a clinical trial of NAC + S was compared to a historic cohort of patients undergoing concurrent chemoradiation (CCRT) to compare disease-free survival (DFS). RESULTS Fifty-five patients were treated with NAC + S and 142 with CCRT. Stage-matched patients undergoing CCRT had higher frequency of smoking and alcohol consumption. 5-year DFS in the NAC + S group was 96.1% (95% CI 90.8-100) compared to 67.6% (95% CI 50.7-84.5) for CCRT (P = .01). At 12 months from treatment, 24.5% of patients undergoing CCRT and none of the patients in the NAC + S were feeding tube dependent (P

BACKGROUND We ascertain the association of postoperative infection on survival in patients with locoregionally advanced oral cavity squamous cell carcinoma (OCSCC). METHODS A retrospective study of patients with stage III/IVA OCSCC undergoing curative-intent surgery was performed. Postoperative infection was considered within 30 days after surgery. Kaplan-Meier survival curves were used to compare overall survival (OS) in patients with postoperative infection. Cox regression and propensity-score matching were used to adjust for confounders. RESULTS Fifty-four of 114 patients had a postoperative infection. The 5-year OS in patients with a postoperative infection (24.1%) was lower than those without (65.2%; P

Background A longitudinal curriculum was developed in conjunction with anesthesiologists, otolaryngologists, emergency physicians and experts in medical simulation and education. Methods Residents participated in four different simulation-based training modules using animal models, cadavers, task trainers, and crisis scenarios using high fidelity manikins. Scenarios were based on various clinical settings (i.e. emergency room, operating room) and were followed by video-assisted structured debriefings. Participants completed both a self-assessment questionnaire and an exit survey using five-point Likert scales. Results 31 otolaryngology residents participated in the curriculum. Residents reported simulation training significantly improved technical skills such as tracheostomy, cricothyroidotomy and pediatric intubation (p 90% (28/31) of participants found the modules of the curriculum to be useful and would recommend them to others. Conclusion A longitudinal simulation-based medical curriculum can be an effective method to teach airway management and teamwork skills to otolaryngology residents.

BACKGROUND Hematologic markers, such as the neutrophil-to-lymphocyte ratio (NLR), characterize the inflammatory response to cancer and are associated with poorer survival in various malignancies. We evaluate the effect of pretreatment NLR on overall survival (OS) in patients with head and neck squamous cell carcinoma (HNSCC). METHODS Using multiple databases, a systematic search for articles evaluating the effect of NLR on OS in patients with HNSCC was performed. An inverse variation, random-effects model was used to analyze the data. RESULTS A total of 24 of 241 articles, including 6479 patients, were analyzed. The combined hazard ratio for OS in patients with an elevated NLR (range 2.04-5) was 1.78 (confidence interval [CI] 1.53-2.07; P

Background Learners often utilize online resources to supplement formalized curricula, and to appropriately support learning, these resources should be of high quality. Thus, the objectives of this study are to develop and provide validity evidence supporting an assessment tool designed to assess the quality of educational websites in Otolaryngology- Head & Neck Surgery (ORL-HNS), and identify those that could support effective web-based learning. Methods After a literature review, the Modified Education in Otolaryngology Website (MEOW) assessment tool was designed by a panel of experts based on a previously validated website assessment tool. A search strategy using a Google-based search engine was used subsequently to identify websites. Those that were free of charge and in English were included. Websites were coded for whether their content targeted medical students or residents. Using the MEOW assessment tool, two independent raters scored the websites. Inter-rater and intra-rater reliability were evaluated, and scores were compared to recommendations from a content expert. Results The MEOW assessment tool included a total of 20 items divided in 8 categories related to authorship, frequency of revision, content accuracy, interactivity, visual presentation, navigability, speed and recommended hyperlinks. A total of 43 out of 334 websites identified by the search met inclusion criteria. The scores generated by our tool appeared to differentiate higher quality websites from lower quality ones: websites that the expert “would recommend” scored 38.4 (out of 56; CI [34.4–42.4]) and “would not recommend” 27.0 (CI [23.2–30.9]). Inter-rater and intra-rater intraclass correlation coefficient were greater than 0.7. Conclusions Using the MEOW assessment tool, high quality ORL-HNS educational websites were identified.

PURPOSE Direct assessment of trainee performance across time is a core tenet of competency-based medical education. Unlike variability of psychomotor skills across levels of expertise, performance variability exhibited by a particular trainee across time remains unexplored. The goal of this study was to document the consistency of individual surgeons' technical skill performance. METHOD A secondary analysis of assessment data (collected in 2010-2012, originally published in 2015) generated by a prospective cohort of participants at Montreal Children's Hospital with differing levels of expertise was conducted in 2017. Trained raters scored blinded recordings of a myringotomy and tube insertion performed 4 times by junior and senior residents and attending surgeons over a 6-month period using a previously reported assessment tool. Descriptive exploratory analyses and univariate comparison of standard deviations (SDs) were conducted to document variability within individuals across time and across training levels. RESULTS Thirty-six assessments from 9 participants were analyzed. The SD of scores for junior residents was highly variable (5.8 out of a scale of 30 compared with 1.8 for both senior residents and attendings [F(2,19) = 5.68, P < 0.05]). For a given individual, the range of scores was twice as large for junior residents than for senior residents and attendings. CONCLUSIONS Surgical residents may display highly variable performances across time, and individual variability appears to decrease with increasing expertise. Operative skill variability could be underrepresented in direct observation assessment; emphasis on an adequate amount of repetitive evaluations for junior residents may be needed to support judgments of competence or entrustment.

Inverted papillomas are tumors of the sinonasal tract with a propensity to recur. Raman spectroscopy can potentially identify inverted papillomas from other tissue based on biochemical signatures. A pilot study comparing Raman spectroscopy to histopathology for 3 types of sinonasal tissue was performed. Spectral data of biopsies from patients with normal sinonasal mucosa, chronic rhinosinusitis, and inverted papillomas are compared to histopathology using principal component analysis and linear discriminant analysis after data preprocessing. A total of 18 normal, 15 chronic rhinosinusitis, and 18 inverted papilloma specimens were evaluated. The model distinguished normal sinonasal mucosa, chronic rhinosinusitis, and inverted papilloma tissue with an overall accuracy of 90.2% (95% confidence interval, 0.86-0.94). In conclusion, Raman spectroscopy can distinguish inverted papilloma, normal sinonasal mucosa, and chronically rhinosinusitis tissue with acceptable accuracy.

To determine the effect of current smoking status on 30-day postoperative adverse events in patients undergoing otologic surgery.Retrospective cohort study.Database of the American College of Surgeons National Surgical Quality Improvement Program from 2006 to 2016.Adult patients undergoing middle ear and mastoid surgery were included. Preoperative smoking status was determined, and adverse events within 30 days of surgery were recorded. Descriptive statistics were used to characterize the study sample. Multivariable logistic regression was performed to identify the association between sociodemographic and clinical variables and postoperative adverse events. Population-attributable fractions were then calculated.A total of 10,684 patients who underwent otologic surgery were included, of whom 2036 (19.1%) were smokers. The most commonly performed surgery was tympanoplasty with and without ossicular chain reconstruction, followed by canal wall up tympanomastoidectomy. Adverse events occurred in 221 (2.1%) patients; the most common was superficial wound infections (n = 99, 0.9%). In smokers, the odds ratio for any adverse event was 1.97 (95% CI, 1.42-2.71). The odds ratios (95% CIs) for superficial wound infections, wound dehiscence, and 30-day readmission among smokers were 1.89 (1.32-2.86), 3.92 (1.26-11.60), and 1.84 (1.15-2.87), respectively. The population-attributable fraction for any adverse event in smokers was 15.5%.In patients undergoing otologic surgery, smokers are more likely than nonsmokers to have postoperative adverse events-in particular, wound infections, wound dehiscence, and readmission to hospital.

Background Reported rates of thyroid cancer in Graves’ disease (GD) vary widely. The aim of this study was to evaluate the prevalence of papillary thyroid carcinoma (PTC), including aggressive forms, in GD compared to matched controls undergoing thyroidectomy. Furthermore, it seeks to elucidate any patient- or tumour-associated factors predictive of malignancy or an aggressive course. Methods We performed a matched cohort study of GD patients undergoing thyroidectomy at our institution between 2006 to 2018. Clinicodemographic factors, preoperative characteristics, surgical factors, final histopathology as well postoperative course were collected. Aggressive PTC was defined as evidence of lymph node metastasis, extrathyroidal extension, gross vascular invasion and/or aggressive histologic variants. Prevalence of PTC was compared with sex, age and nodule size-matched euthyroid patients that underwent thyroidectomy in the same time period. Results A total of 132 patients were included in the study with a mean age of 46 (±14) years. Malignancy was identified in 36/66 (55%) patients with GD; 20/66 (30%) were incidental carcinomas and 9/66 (14%) were associated with aggressive pathologic features. In the aggressive group, lymph node metastasis to the central compartment was present in 8 (12%) cases, extrathyroidal extension in 4 (6%) cases and one (1.5%) patient had a diffuse sclerosing tumor variant. No significant differences in outcome were found between the two groups. GD patients were more likely to have incidental carcinomas (p = 0.035). Adjusting for baseline patient characteristics, GD patients demonstrated an increased likelihood of harbouring a malignancy (odds ratio (OR) = 2.67; 95% confidence interval (CI) 1.00–7.18) compared to controls. Conclusion More than half of patients with GD undergoing thyroidectomy had concurrent thyroid malignancy with aggressive features present in 14% of patients. GD may confer a heightened risk of thyroid cancer; thyroid nodules should therefore be carefully investigated.

Background A paradigm shift has led to de-escalation trials for the treatment of HPV-positive oropharynx cancer (OPC). The objective of this study was to assess the ability of tumor volume reduction on imaging to predict pathological response to neoadjuvant chemotherapy in patients with HPV-positive OPC. Methods A prospective observational study of 54 patients with HPV-positive OPC enrolled in a clinical trial of neoadjuvant chemotherapy followed by surgery was performed. Patients underwent three cycles of induction chemotherapy (cisplatin/docetaxel); prechemotherapy and postchemotherapy imaging were obtained. Receiver operating characteristic curves and logistic regression analyses were used. Results The complete pathologic response (pCR) rate at primary and nodal sites were 72% and 57%, respectively. Tumor volume reduction of ≥90% following induction chemotherapy predicted pCR of the primary tumor. Conclusions Neoadjuvant chemotherapy followed by definitive transoral surgery is a new paradigm worthy of further investigation and MRI is a reliable modality to assess preoperative response.

Background Acute invasive fungal infections of the head and neck secondary to tyrosine kinase inhibitors are rare and potentially life-threatening events. Case presentation We report a case of mucormycosis of the thyroid gland in a patient known for chronic lymphocytic leukemia receiving ibrutinib who presented with a rapidly growing thyroid nodule and dysphonia. An acute invasive fungal infection was identified on a core needle biopsy; mucormycosis was confirmed on culture. The patient was successfully treated with surgical debridement and long-term antifungal therapy. Conclusion Patients on ibrutinib may be at risk of acute invasive fungal infections of the head and neck.

We developed a high efficiency endocrine operative protocol based on a mathematical programming approach, process reengineering, and value-stream mapping to increase the number of operations completed per day without increasing operating room time at a tertiary-care, academic center.Using this protocol, a case-control study of 72 patients undergoing endocrine operation during high efficiency days were age, sex, and procedure-matched to 72 patients undergoing operation during standard days. The demographic profile, operative times, and perioperative complications were noted.The average number of cases per 8-hour workday in the high efficiency and standard operating rooms were 7 and 5, respectively. Mean procedure times in both groups were similar. The turnaround time (mean ± standard deviation) in the high efficiency group was 8.5 (±2.7) minutes as compared with 15.4 (±4.9) minutes in the standard group (P .001). Transient postoperative hypocalcemia was 6.9% (5/72) and 8.3% (6/72) for the high efficiency and standard groups, respectively (P = .99).In this study, patients undergoing high efficiency endocrine operation had similar procedure times and perioperative complications compared with the standard group. The proposed high efficiency protocol seems to better utilize operative time and decrease the backlog of patients waiting for endocrine operation in a country with a universal national health care program.

Objectives/Hypothesis Despite the transition to competency-based education in surgery, few standardized assessment tools exist in otolaryngology training. In particular, myringotomy and tympanostomy tube insertion (M+T) is a common surgical procedure with few validated assessment tools available. Our objectives were to develop an objective structured assessment of operative skills in M+T and to provide validity evidence for the developed assessment tool within otolaryngology training. Study Design Prospective study involving the evaluation of an assessment tool. Methods Through consultation with a panel of experts in otolaryngology and medical education we developed a Task-Specific Checklist and Global Rating Scale for M+T. Postgraduate year 2 junior residents, postgraduate year 3 senior residents, and attending otolaryngologists were video recorded performing M+T at a tertiary care pediatric hospital. The videos were subsequently reviewed and independently evaluated by three blinded raters from an unaffiliated academic institution. Results The average score of junior residents, senior residents, and attending otolaryngologists using the Task-Specific Checklist was 21.7/30 (±7.1), 26.3/30 (±3.5), and 27.3/30 (±6.2), respectively (P = .04). For the Global Rating Scale, the scores for junior residents, senior residents, and attending surgeons were 27.7/50 (±11.2), 34.5/50 (±9.5), and 45.1/50 (±4.6), respectively (P < .001). The inter-rater and intrarater reliability were both above 0.88. Conclusions The Task-Specific Checklist and Global Rating Scale for M+T appear reliable, with validity evidence supporting their use in otolaryngology training.

IMPORTANCE: Frailty represents a multidimensional syndrome that is increasingly being used to stratify risk in surgical patients. Current frailty risk models are limited among those undergoing thyroid or parathyroid surgery. OBJECTIVE: To develop and compare preoperative risk indices to determine factors associated with short-term major postoperative adverse events in patients undergoing thyroid or parathyroid surgery. DESIGN, SETTING, AND PARTICIPANTS: This cohort study evaluated 154 895 patients in the American College of Surgeons National Surgical Quality Improvement Program who underwent thyroid or parathyroid surgery from January 1, 2007, to December 31, 2016. EXPOSURES: Preoperative frailty-related and surgical factors from a derivation cohort were evaluated using simple and multiple logistic regression. Variables potentially associated with postoperative adverse events were subsequently combined into a personalized preoperative Cervical Endocrine Surgery Risk Index (CESRI) and compared with existing risk models using the validation cohort. MAIN OUTCOMES AND MEASURES: Composite variable of any major postoperative adverse event, including death, within 30 days of surgery. RESULTS: Of the 154 895 operations reviewed, 3318 patients (2.1%; 2296 women and 1022 men; mean [SD] age, 56.1 [15.6] years) experienced a major postoperative adverse event, with 163 deaths (0.1%). Older age (age, ≥80 years: odds ratio [OR], 2.35; 95% CI, 1.74-3.13), inpatient status (OR, 3.55; 95% CI, 3.08-4.11), male sex (OR, 1.49; 95% CI, 1.29-1.71), current tobacco smoking (OR, 1.25; 95% CI, 1.05-1.48), dyspnea (OR, 1.58; 95% CI, 1.29-1.91), recent weight loss (OR, 1.88; 95% CI, 1.23-2.78), functional dependence (OR, 2.77; 95% CI, 2.05-3.69), obesity (OR, 1.33; 95% CI, 1.10-1.60), anemia (OR, 2.14; 95% CI, 1.82-2.52), leukocytosis (OR, 1.73; 95% CI, 1.38-2.14), hypoalbuminemia (OR, 1.87; 95% CI, 1.56-2.23), use of anticoagulation (OR, 2.16; 95% CI, 1.64-2.81), and length of surgery (>4 hours: OR, 2.92; 95% CI, 2.37-3.59) were independently associated with major adverse events or death on multiple regression analysis (C statistic, 0.77; 95% CI, 0.76-0.78). The area under the curve of the CESRI to determine major adverse events, including death, using the validation cohort was 0.63 (95% CI, 0.61-0.64), with a sensitivity of 0.66 (95% CI, 0.64-0.68) and specificity of 0.66 (95% CI, 0.65-0.66). The CESRI outperformed other risk models for determining adverse events (CESRI vs 5-Factor Modified Frailty Index: delta C index, 0.11; 95% CI, 0.09-0.13; CESRI vs American Society of Anesthesiologists Physical Status Classification System: delta C index, 0.05; 95% CI, 0.03-0.07; CESRI vs American College of Surgeons Risk Calculator: delta C index, 0.02; 95% CI, 0.01-0.03; and CESRI vs Head and Neck Surgery Risk Index: delta C index, 0.04; 95% CI, 0.03-0.06). CONCLUSIONS AND RELEVANCE: This study suggests that the CESRI is able to determine major postoperative adverse events in patients undergoing thyroid or parathyroid surgery.

Summary Background In-office laryngeal surgery is taking on a more commonplace role in the treatment of laryngeal disorders. The potassium-titanyl-phosphate (KTP) laser has been a resourceful adjunct to the management of patients with mucosal lesions of the vocal cords. However, a paucity of data exists for its use in postintubation granulomas treated in-office. Clinical Case A 43-year-old female presented with voice hoarseness and found to have a large obstructing postintubation granuloma which was treated by in-office KTP laser and en masse excision. Conclusions We report the successful case of a patient receiving in-office treatment for a large vocal process granuloma using the KTP laser with en masse excision. The combined use of the KTP laser and forceps in-office can be valuable to the surgical management of vocal process granulomas, given their numerous recurrences. New avenues in office-based surgical management of laryngeal disorders can offer accessibility and decreased morbidity to patients.

Background A commonly employed treatment for advanced staged oropharyngeal squamous cell carcinoma (OPSCC) is concurrent radiation and chemotherapy with cisplatin as the gold standard. Carboplatin is reported to have the same radiopotentiation properties and a superior side effect profile; however, its use in head and neck cancer has been limited due to the paucity of data and reported hematologic side effects. In this study, we describe our institution’s experience with carboplatin, paclitaxel and radiation in the treatment of oropharyngeal squamous cell carcinoma over a 10 year period. Methods A retrospective chart review of patients aged 18 to 80 years old with stage III-IV OPSCC treated with weekly carboplatin, paclitaxel and intensity modulated radiotherapy (IMRT) was performed. Data collected included patient demographics, tumor location and stage and survival outcomes. In addition, we noted treatment morbidities according to the Radiation Therapy Oncology Group (RTOG) scoring criteria scale. The data was analyzed using the student’s t-test and analysis of variables. Results Over a 10 year period, 160 patients received chemoradiation with carboplatin and paclitaxel for OPSCC. One-hundred-four and 65 patients were followed for at least 3 and 5 years, respectively. Overall survival for all patients was 81.7 and 70.7 % at 3 and 5 years, respectively. Disease free survival and locoregional recurrence-free survival at 5 years was 64.6 and 89.2 %, respectively. There was no association of survival with stage, regional nodal status or subsite. The most common side effect attributed to treatment was acute dysphagia (75.25 %) followed by odynophagia, xerostomia and hypogeusia. Hospitalizations and non-hospitalization emergency department visits attributed to treatment totalled 33 and 11, respectively. Hematologic toxicities greater than grade II were: 11.9 % neutropenia, 6.3 % anemia, 1.8 % thrombocytopenia. The incidence of febrile neutropenia was 5.0 % (8/160). Conclusion In conclusion, the overall, disease-free and locoregional recurrence-free survival of patients treated with carboplatin and radiotherapy for advanced stage OPSCC parallels what has been described in the literature for cisplatin, with an acceptable side effect profile.

Objective To identify clinico-radiologic factors associated with incomplete anterior cranial fossa (ACF) meningioma resection via an endoscopic endonasal approach. Method Patients undergoing endoscopic endonasal resection of an ACF meningioma were retrospectively accrued from two university-affiliated centers. Demographic profiles and radiologic findings, including tumor dimensions and morphology, anatomic location, and vascular involvement, were stratified according to the extent of resection. Results Twenty-five patients were included in this study. Factors associated with incomplete surgical resection via an endonasal route were: presence of hyperostosis ( P = 0.04), cavernous internal carotid artery involvement ( P = 0.001), maximal dural tail length in the transverse plane ( P = 0.006), and its ratio to the inter-fovea ethmoidalis distance ( P = 0.01). Using a multiple regression analysis, only cavernous internal carotid artery involvement ( P = 0.002) and a large dural tail length to inter-foveal distance ratio ( P = 0.04) were significant predictors of incomplete resection (multiple correlation coefficient = 0.71). The combination of predictive factors to determine the likelihood of complete endoscopic resection produced a scoring system with a sensitivity and specificity of 85.7% (95% confidence interval [CI], 42.1–99.6] and 100% (95% CI, 81.5–100), respectively. Conclusion The use of a simple scoring system outlined in our study can facilitate proper patient selection for endoscopic endonasal resection of ACF meningiomas.

Hypocalcemia following thyroidectomy often prolongs hospital stay and is potentially life-threatening. The objective of this study is to determine whether the season when thyroidectomy is performed is associated with postoperative hypocalcemia.Retrospective case series of patients undergoing thyroid surgery from 2009 to 2015.Tertiary care academic institution in Montreal, Canada.A consecutive sample of 823 patients undergoing thyroidectomy by a single high-volume otolaryngologist for a suspected or confirmed thyroid malignancy. Patient demographics, procedure type, calcium and vitamin D supplementation, and seasonal rate of hypocalcemia postthyroidectomy were calculated and compared.Average seasonal rates of postthyroidectomy hypocalcemia in the winter, spring, summer, and autumn were, respectively, 8.3% (8 of 216), 7.3% (12 of 165), 1.5% (3 of 201), and 3.5% (8 of 228; P.005). Patients operated in the winter were 5.6 times more likely to develop hypocalcemia as compared with those in the summer (P.01; 95% confidence interval: 1.7-18.7). In a multiple regression analysis factoring in season when surgery was performed, procedure type, and preoperative vitamin D/calcium supplementation, surgery occurring in the winter predicted a hypocalcemia event (correlation coefficient [SE]: 0.72 [0.024], P = .026; 0.006 [0.025], P = .81; 0.004 [0.019], P = .82, respectively).In this study, patients undergoing thyroidectomy in the winter months were more likely to develop postoperative hypocalcemia when compared with those operated in the summer. Further studies are needed to understand the role of vitamin D in the observed seasonal difference in hypocalcemia rates.
