Abstract
OBJECTIVE To compare billing practices, reimbursement rates, and patient populations of otolaryngology (ORL) physicians practicing in rural and urban settings. STUDY DESIGN Retrospective cross-sectional study. SETTING Medicare Provider Utilization and Payment Data: Physician and Other Supplier Data. METHODS Medicare-allowed payments, number of services, and number of patients were gathered along with patient population comorbidity statistics, including average hierarchical condition category risk scores. RESULTS In 2019, 92% of the overall total 8959 ORL physicians practiced in an urban setting. These 8243 urban ORL physicians, on average, billed for 51 (interquartile range [IQR], 31-67) unique Healthcare Common Procedure Coding System (HCPCS) codes, cared for 393 (IQR, 172-535) Medicare patients, performed 1761 (IQR, 502-2070) services, and collected $139,957 (IQR, $55,527-$178,479) per provider. In contrast, the 704 rural ORL physicians, on average, billed for a greater number of unique HCPCS codes (59; IQR, 37-77; P < .001), treated more Medicare patients (445; IQR, 242-614; P < .001), and performed more services (2330; IQR, 694-2748; P < .001) but collected about the same per provider ($141,035; IQR, $56,555-$172,864; P = .426). Older age was associated with rural practice (P = .027). Among both urban and rural ORL physicians, the variety and complexity of procedures and patient comorbidity profiles were comparable. CONCLUSION Most ORL physicians practice in large urban settings, a finding potentially related to financial sustainability and career opportunity. With an already small workforce, the aging rural ORL physician population is an identifiable weak point in the otolaryngology specialty that must be addressed with geo-specific recruitment campaigns, rural work incentivization, and the development of career advancement opportunities in rural areas.

Abstract
BACKGROUND Venous malformations (VMs) are congenital vascular lesions caused by enlarged and ectatic venous channels. Current methods of treatment for VMs involve a combination of sclerotherapy, laser therapy, and surgical resection. While sclerotherapy remains the most commonly used treatment for small VMs, surgery remains an important tool for isolated VMs or larger VMs with higher flow due to potential local and systemic side effects associated with the use of certain sclerosing agents. METHODS/RESULTS Here we present a case of a patient with a naso- and oropharyngeal venous malformation which was successfully resected with endoscopic-assisted transoral surgery. CONCLUSIONS This is a low-fingerprint technique to tumors of the oropharynx with excellent visualization and maneuverability in cases where TORS is not an option. This technique does not require palate splitting or excessive retraction, allows multiple surgeons to work simultaneously, and is associated with significantly lower morbidity than transcervical techniques.

Abstract
OBJECTIVE To determine demographic factors and clinicopathologic characteristics associated with survival in young patients (age <45 years) with early- (I-II) or late-stage (III-IV) oral tongue squamous cell carcinoma (OTSCC). STUDY DESIGN Retrospective database review. SETTING National Cancer Database. METHODS A retrospective review of 3262 OTSCC cases in young patients between 2005 and 2014 was performed by using data from the National Cancer Database. Factors affecting 2-year survival in patients with early- and late-stage disease were evaluated via univariate and multivariate analyses. RESULTS Overall, 1899 patients with early-stage OTSCC and 1363 with late-stage OTSCC were analyzed. In multivariate analysis of early-stage OTSCC, high tumor grade (hazard ratio, 2.08 [95% CI, 1.45-2.99]), local metastasis (2.85 [1.37-5.95]), and tumor size (1.04 [1.02-1.07]) were predictors of mortality. In late-stage OTSCC, African American race (2.79 [1.40-5.56]), positive surgical margins (1.77 [1.07-2.93]), local metastasis (2.20 [1.03-4.72]), distant metastasis (11.66 [2.10-64.73]), depth of invasion (1.03 [1.01-1.05]), and tumor size (1.01 [1.003-1.01]) were predictors of mortality. Subset analysis of clinical N0-stage tumors revealed that treatment with surgery alone was associated with improved survival (P < .001). CONCLUSION Positive lymph nodes, high tumor grade, and larger tumor size were associated with increased mortality risk in early- and late-stage young OTSCC. More aggressive up-front treatment, including extirpative surgery and elective neck dissection, may be associated with improved outcomes and should be considered in early-stage cases with high-risk features.

Abstract
BACKGROUND AND PURPOSE There is active research involving the radiographic appearance of the skull base following reconstruction. The purpose of this study was to describe the radiographic appearance of the vascularized pedicle nasoseptal flap after endoscopic skull base surgery across time. MATERIALS AND METHODS We performed chart and imaging review of all patients with intraoperative nasoseptal flap placement during endoscopic skull base surgery at a tertiary academic skull base surgery program between July 2018 and March 2021. All patients underwent immediate and delayed (>3 months) postoperative MR imaging. Primary outcome variables included flap and pedicle enhancement, flap thickness, and flap adherence to the skull base. RESULTS Sixty-eight patients were included. Flap (P = .003) enhancement significantly increased with time. Mean nasoseptal flap thickness on immediate and delayed postoperative scans was 3.8 and 3.9 mm, respectively (P = .181). The nasoseptal flap adhered entirely to the skull base in 37 (54.4%) and 67 (98.5%) patients on immediate and delayed imaging, respectively (P < .001). CONCLUSIONS Our findings demonstrate heterogeneity of the nasoseptal flap appearance after skull base reconstruction. While it is important for surgeons and radiologists to evaluate variations in flap appearance, the absence of enhancement and lack of adherence to the skull base on immediate postoperative imaging do not appear to predict reconstructive success and healing, with many flaps "self-adjusting" with time.

Abstract
OBJECTIVES To evaluate the influence of facility case-volume on survival in patients with locally advanced papillary thyroid cancer (PTC), and to identify prognostic case-volume thresholds for facilities managing this patient population. STUDY DESIGN Retrospective database study. METHODS The 2004-2017 National Cancer Database was queried for patients receiving definitive surgery for locally advanced PTC. Using K-means clustering and multivariable Cox proportional-hazards (CPH) regression, two groups with distinct spectrums of facility case-volumes were generated. Multivariable CPH regression and Kaplan-Meier analysis assessed for the influence of facility case-volume and the prognostic value of its stratification on overall survival (OS). RESULTS Of 48,899 patients treated at 1304 facilities, there were 34,312 (70.2%) females and the mean age was 48.0 ± 16.0 years. Increased facility volume was significantly associated with reduced all-cause mortality (HR 0.996; 95% CI, 0.992-0.999; p = 0.008). Five facility clusters were generated, from which two distinct cohorts were identified: low (LVF; <27 cases/year) and high (HVF; ≥27 cases/year) facility case-volume. Patients at HVFs were associated with reduced mortality compared to those at LVFs (HR 0.791; 95% CI, 0.678-0.923, p = 0.003). Kaplan-Meier analysis of propensity score-matched N0 and N1 patients demonstrated higher OS in HVF cohorts (all p < 0.001). CONCLUSIONS Facility case-volume was an independent predictor of improved OS in locally advanced PTC, indicating a possible survival benefit at high-volume medical centers. Specifically, independent of a number of sociodemographic and clinical factors, facilities that treated ≥27 cases per year were associated with increased OS. Patients with locally advanced PTC may, therefore, benefit from referrals to higher-volume facilities. LEVEL OF EVIDENCE 4 Laryngoscope, 133:443-450, 2023.

Abstract
PURPOSE OF REVIEW The aim of this article is to review the current literature regarding development of new or recurrent inflammation of uninvolved contralateral sinuses in unilateral allergic fungal rhinosinusitis (AFRS) and discuss management strategies. RECENT FINDINGS AFRS is a subtype of chronic rhinosinusitis with nasal polyposis (CRSwNP) that can manifest as either unilateral or bilateral disease. Particular to AFRS compared with other CRSwNP subtypes is the high propensity for recurrence. Multiple recent studies have evaluated the recurrence rate of uninvolved contralateral sinuses in unilateral AFRS and demonstrated eventual involvement of the nondiseased side. Additionally, postoperative medical therapy of the nondiseased side reduced recurrence rates overall. SUMMARY Recurrence of AFRS is high in both the ipsilateral and contralateral sinuses. Upfront bilateral medical and/or surgical treatment of patients presenting with unilateral AFRS may be considered to improve long-term inflammatory control.

Abstract
OBJECTIVE To evaluate differences in treatment outcomes for head and neck mucosal melanoma (HNMM) patients seen at academic versus nonacademic centers and high versus low volume facilities. STUDY DESIGN Retrospective cohort study. SETTING National Cancer Database. METHODS Differences in treatment course and overall survival (OS) by facility type and volume were assessed for 2772 HNMM cases reported by the 2004 to 2017 National Cancer Database. A subgroup analysis was performed with a smaller cohort containing staging data. The analysis employed Kaplan-Meier and Cox proportional hazards models. RESULTS A higher proportion of patients treated at academic centers within the HNMM cohort waited longer for surgery after diagnosis (p < .001), had negative surgical margins (p < .001), and were readmitted to the hospital within 30 days of surgery (p = .001); these relationships remained significant when controlling for cancer stage. Kaplan-Meier analysis demonstrated higher 5-year OS for patients treated at academic versus nonacademic facilities within the main cohort (32.5% ± 1.3% vs 27.3% ± 1.5%; p = .006) and within the stage-controlled subgroup (34.8% ± 2.1% vs 27.2% ± 2.6%; p = .003). Treatment at high volume versus low volume facilities was associated with improved 5-year OS for main cohort patients (33.5% ± 1.7% vs 28.8% ± 1.2%; p = .016) but not for subgroup patients (35.3% ± 2.7% vs 30.1% ± 2.1%; p = .100). Upon multivariate analysis controlling for demographic and oncologic factors, there was no significant difference in OS by facility type (main cohort: odds ratio [OR] = 1.07, 95% confidence interval [CI] = 1.01-1.21; subgroup: OR = 1.13, 95% CI = 0.97-1.32). CONCLUSION Neither facility type nor surgical volume predicts overall survival in HNMM.

Abstract
OBJECTIVE To assess how traditional, simple markers of health independently affect postoperative morbidity of mandibular fracture open reduction-internal fixations (ORIFs). STUDY DESIGN Cohort study. SETTING National Surgical Quality Improvement Project (NSQIP) Database. METHODS The 2005 to 2017 NSQIP database was queried for patients who underwent mandibular ORIF. To control for the severity of the trauma, an additional "concurrent surgery" variable was created. A modified 5-item frailty index was calculated based on the following: presurgery-dependent functional status, chronic hypertension, diabetes mellitus, history of chronic obstructive pulmonary disease, and history of congestive heart failure. RESULTS Among 1806 patients with mandibular ORIFs (mean age 34.8 ± 15.4 years), modified frailty index (mFI) was associated with 30-day medical complications (p < .001), reoperation (p < .001), and readmission (p = .005) on univariate analysis. Increased age was associated with prolonged hospitalization (p < .001) and medical complications (p < .001). The increased American Society of Anesthesiologists (ASA) score was associated with all endpoints (p ≤ .003), while increased body mass index (BMI) was associated with none. On multivariate analysis, only increased ASA was associated with any adverse event (reference: ASA 1; ASA 2, odds ratio [OR]: 2.17 [95% confidence interval, CI: 2.17-3.71], p = .004; ASA 3-4, OR: 3.63 [95% CI: 1.91-6.91], p < .001). Similarly, mFI and BMI were not independently associated with prolonged hospitalization (≥2 days) (p ≥ .015), but 65+ age (reference: 18-49; OR: 2.33 [95% CI: 1.40-3.86], p = .001) and ASA 3 to 4 groups (reference: ASA 1; OR: 3.26 [95% CI: 2.06-5.14], p < .001) were. CONCLUSION ASA status and age are more useful modalities than mFI or BMI in predicting poor postoperative morbidity in mandibular ORIF. These simple metrics can assist with managing surgeons' expectations for mandibular ORIF patients.

Abstract
PURPOSE This study aimed to evaluate the efficacy of different treatment combinations on patient survival in intermediate-risk differentiated thyroid cancer (DTC). METHODS The 2004-2017 National Cancer Database was queried for intermediate-risk papillary (PTC), follicular (FTC), or Hurthle cell (HTC) thyroid cancer patients. Four treatments were analyzed using Kaplan Meier and multivariable Cox regression: surgery, surgery with adjuvant radioiodine ablation (S + RAI), surgery with adjuvant thyroid-stimulating hormone suppression therapy (S + THST), and S + RAI + THST. Kaplan-Meier and multivariable Cox proportional-hazards analyses evaluated treatment-associated overall survival (OS). RESULTS Of 65,736 patients, 72.2% were female and the average age was 45.4 ± 15.4 years. The 10-year OS rates for PTC, FTC, and HTC were 93.2%, 85.2%, and 78.5%, respectively. S + RAI + THST exhibited higher OS than surgery alone and S + RAI (all p < 0.05). Compared to surgery alone, S + RAI + THST demonstrated reduced mortality in PTC (Hazard Ratio [HR]: 0.628, p < 0.001), FTC (HR: 0.490, p < 0.001), and HTC (HR: 0.520, p = 0.006). Similarly, adjuvant RAI + THST reduced mortality regardless of lymphovascular invasion (HR: 0.490, p < 0.001), N1a (HR: 0.570, p < 0.001) or N1b metastasis (HR: 0.621, p < 0.001), or positive margin status (HR: 0.572, p < 0.001). CONCLUSIONS Treatment combinations demonstrated varying efficacies in intermediate-risk DTC depending on histology and tumor characteristics, with S + RAI + THST exhibiting the greatest treatment response.

Abstract
OBJECTIVE To evaluate the prognostic strengths of American Joint Committee on Cancer (AJCC) staging and American Thyroid Association (ATA) risk classification in well-differentiated thyroid cancer (DTC), and their implications in guiding medical decision-making and epidemiological study designs. METHODS The 2004-2017 National Cancer Database was queried for DTC patients. Cox proportional hazards (CPH) and Kaplan-Meier analyses modeled patient mortality and overall survival, respectively. Each CPH model was evaluated by its concordance index, measure of explained randomness (MER), Akaike information criterion (AIC), and area under receiver operating characteristic curve (AUC). RESULTS Overall, 134,226 patients were analyzed, with an average age of 48.1 ± 15.1 years (76.9% female). Univariate CPH models using AJCC staging demonstrated higher concordance indices, MERs, and AUCs than those using ATA risk classification (all p < 0.001). Multivariable CPH models using AJCC staging demonstrated higher concordance indices (p = 0.049), MERs (p = 0.046), and AUCs (p = 0.002) than those using ATA risk classification. The AICs of multivariable AJCC staging and ATA risk models were 7.564 × 104 and 7.603 × 104 , respectively. AJCC stage I tumors were associated with greater overall survival than those classified as ATA low risk, whereas AJCC stages II-III and stage IV tumors demonstrated worse survival than ATA intermediate- and high-risk tumors, respectively (all p < 0.001). CONCLUSION AJCC staging may be a more predictive system for patient survival than ATA risk. The prognostic utility of these two systems converges when additional demographic and clinical factors are considered. AJCC staging was found to classify patients across a wider range of survival patterns than the ATA risk stratification system. LEVEL OF EVIDENCE 4 Laryngoscope, 133:205-211, 2023.

Abstract
BACKGROUND Postoperative management strategies for endoscopic skull base surgery (ESBS) vary widely because of limited evidence-based guidance. METHODS The PubMed, EMBASE, and Cochrane databases were systematically reviewed from January 1990 through February 2022 to examine 18 postoperative considerations for ESBS. Nonhuman studies, articles written in a language other than English, and case reports were excluded. Studies were assessed for levels of evidence, and each topic's aggregate grade of evidence was evaluated. RESULTS A total of 74 studies reporting on 18 postoperative practices were reviewed. Postoperative pain management, prophylactic antibiotics, and lumbar drain use had the highest grades of evidence (B). The literature currently lacks high quality evidence for a majority of the reviewed ESBS precautions. There were no relevant studies to address postoperative urinary catheter use and medical intracranial pressure reduction. CONCLUSION The evidence for postoperative ESBS precautions is heterogeneous, scarce, and generally of low quality. Although this review identified the best evidence available in the literature, it suggests the urgent need for more robust evidence. Therefore, additional high-quality studies are needed in order to devise optimal postoperative ESBS protocols.

Abstract
This study evaluates the gender distribution of Centralized Otolaryngology Research Efforts (CORE) grants by research subspeciality over the past decade. Demographic information on CORE grant recipients from 2010 to 2019 was extracted through an Internet search, and research projects were categorized by subspeciality. Of 343 grants awarded during this period, 127 (37%) were awarded to women. Analysis demonstrated lower absolute rates of CORE funding for women in all fields except pediatrics, but women receive a proportional number of grants for most subspecialities based on their representation within the field.

Primary sinonasal lymphoma: A multi‐institutional experience of clinical presentation, treatment, and outcomes. Int Forum Allergy Rhinol 2022. [PMID: 36433723 DOI: 10.1002/alr.23102] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Revised: 09/28/2022] [Accepted: 10/17/2022] [Indexed: 11/28/2022]
Abstract
BACKGROUND Sinonasal lymphoma (SL) is a heterogeneous, underrecognized neoplastic disorder with limited outcomes data. We sought to better define outcomes by subtype and treatment at 2 referral centers over the past 2 decades. METHODS Demographics, clinicopathologic data, and treatment outcomes for patients treated for SL were queried from January 1, 2000 to December 31, 2021 at 2 tertiary academic medical centers. RESULTS Eighty-four patients were included, with an average age at diagnosis of 63.4 ± 15 years. There were 34 females (40.5%). The majority of patients had an Eastern Cooperative Oncology Group (ECOG) score of <2 (76.2%) and the most common presenting symptom was facial swelling/pain (26.2%). The most common primary site was the nasal cavity (36.9%). Diffuse large B-cell lymphoma was the most common subtype (46.4%), followed by extranodal NK/T-cell lymphoma (17.9%). Chemotherapy was the most common treatment strategy (n = 59, 70.2%), followed by radiation therapy (n = 35, 41.7%) and immunotherapy (n = 24, 28.6%). Disease-specific survival rates at 1, 5, and 10 years were 85.7%, 73.6%, and 58.6%, respectively. Eighteen patients (21.4%) developed recurrence. On multivariate analysis, higher ECOG score (p < 0.0001) and history of head and neck radiation (p = 0.048) were associated with worse survival. Younger age was associated with greater risk of recurrence (p = 0.022) and male sex was associated with more treatment side effects (p = 0.012). CONCLUSION This is the largest multi-institutional analysis of SL characteristics and outcomes. Our work suggests that, although disease control in the first 5 years is reasonable, 10-year outcomes remain challenging. Further studies are needed to investigate new treatment paradigms and risk stratification.

Abstract
OBJECTIVE While surgery is a critical treatment option for craniopharyngiomas, the optimal surgical approach remains under debate. Herein, we studied a large cohort of craniopharyngioma patients to identify predictors of endoscopic surgery (ES) and to compare survival outcomes between patients undergoing ES versus nonendoscopic surgery (NES). METHODS The National Cancer Database was queried for patients receiving definitive surgical treatment in 2010-2016. Cox proportional hazards and propensity score-adjusted Kaplan-Meier analyses assessed mortality risk and overall survival, respectively. Predictors of surgical approach were evaluated via logistic regression. RESULTS Of 1721 patients, 508 (29.5%) underwent ES, 877 (50.9%) were female, and the average age was 41.8 ± 21.3 years. Matched ES and NES cohorts exhibited 5-year overall survival rates of 88.0% and 79.8%, respectively (P = 0.004). ES was associated with reduced mortality (Hazard Ratio = 0.634; 95% confidence interval [CI], 0.439-0.914; P = 0.015). Patients treated at academic facilities (Odds Ratio [OR] = 2.095; 95% CI, 1.529-2.904; P < 0.001) or diagnosed recently (OR = 1.132; 95% CI, 1.058-1.211; P < 0.001) were more likely to undergo ES, while those with tumor sizes >3 cm (OR = 0.604; 95% CI, 0.451-0.804; P < 0.001) or receiving adjuvant radiotherapy (OR = 0.641; 95% CI, 0.454-0.894; P = 0.010) were more likely to receive NES. Surgical inpatient stays were significantly shorter with ES compared to NES (8.0 vs. 10.5 days, P < 0.001). On linear regression, ES usage increased by 82.4% and NES usage decreased by 23.4% between 2010 and 2016 (R2 = 0.575, P = 0.031). CONCLUSIONS ES of craniopharyngioma was associated with reduced mortality and shorter inpatient stays compared to NES. Factors including tumor size, extent of resection, facility type, and year of diagnosis may predict receiving ES. There is a trend towards increased usage of ES for surgical management of craniopharyngiomas.

Abstract
We characterized the clinical and sociodemographic factors predictive of surgery refusal in pituitary adenoma (PA) patients. We queried the National Cancer Database (NCDB) to identify adult PA patients treated from 2004−2015 receiving or refusing surgery. Multivariate logistic regression and Cox proportional-hazards analysis identified clinical and/or sociodemographic factors predictive of surgery refusal or mortality, respectively. Of the 34,226 patients identified, 280 (0.8%) refused surgery. On multivariate logistic regression, age > 65 (OR: 2.64; p < 0.001), African American race (OR: 1.70; p < 0.001), Charlson-Deyo Comorbidity (C/D) Index > 2 (OR: 1.52; p = 0.047), and government insurance (OR: 2.03; p < 0.001) or being uninsured (OR: 2.16; p = 0.03) were all significantly associated with surgery refusal. On multivariate cox-proportional hazard analysis, age > 65 (HR: 2.66; p < 0.001), tumor size > 2 cm (HR: 1.30; p < 0.001), C/D index > 1 (HR: 1.53; p < 0.001), having government insurance (HR: 1.66; p < 0.001) or being uninsured (HR: 1.67; p < 0.001), and surgery refusal (HR: 2.28; p < 0.001) were all significant predictors of increased mortality. Macroadenoma patients receiving surgery had a significant increase in overall survival (OS) compared to those who refused surgery (p < 0.001). There are significant sociodemographic factors that influence surgery refusal in PA patients. An individualized approach is warranted that considers functional status, clinical presentations, and patient choice.

Abstract
Objective Sinonasal lymphomas are a rare entity that commonly present with nonspecific sinonasal symptoms and are often recognized immediately. Through this review, we aim to summarize important principles in diagnosis and treatment of sinonasal lymphomas, with the goal of disseminating the current knowledge of this under-recognized malignancy to otolaryngologists. Methods Systemic review using PRISMA guidelines of foundational scholarly articles, guidelines, and trials were reviewed focusing on clinical characteristics of key sinonasal lymphoma subtypes, along with available treatments in the otolaryngology, medical oncology, and radiation oncology literature. Results Sinonasal lymphoma are derived from clonal proliferation of lymphocytes at various stages of differentiation, of which diffuse large B-cell lymphoma (DLBCL) and extranodal natural killer/T-cell lymphoma (ENKTL) are the most common. Diagnosis and staging require biopsy with immunohistochemistry in conjunction with imaging and laboratory studies. Treatment is ever evolving and currently includes multi-agent chemotherapy and/or radiation therapy. Conclusion Otolaryngologists may be the first to recognize sinonasal lymphoma, which requires a comprehensive workup and a multidisciplinary team for treatment. Symptoms are nonspecific and similar to many sinonasal pathologies, and it is crucial for otolaryngologists to keep a broad differential. Level of Evidence 5.

Abstract
BACKGROUND The extended endonasal approach has been utilized in the resection of anterior skull base lesions in the pediatric population. There are unique challenges to these patients in the post-operative setting, including patient compliance with medical therapy and post-operative debridements, and a smaller nasal airway that may increase propensity toward scarring. Our objective for this study is to evaluate the incidence of post-operative radiographic inflammation in this patient population using the Lund-Mackay (LM) score. METHODS A single-center, retrospective review of pediatric patients undergoing endoscopic approach to the skull base between 2009 and 2021 was performed. Demographic and clinicopathologic data and pre- and post-operative imaging were analyzed. One-way ANOVA followed by Tukey multiple pairwise comparisons statistical tests were used to compare mean LM scores between groups. RESULTS Seventy-two patients (52 males, 20 females) were identified with a median follow-up of 27 months. All patients underwent an extended endonasal approach for resection of skull base lesions. The mean LM scores were compared between pre-operative MRI, first post-operative MRI > 30 days after surgery, and most recent post-operative MRI. One-way ANOVA was performed with significant differences noted between the groups (p < 0.001). Tukey multiple pairwise comparisons test was then performed and noted significant differences between the pre-operative and first post-operative LM (p < 0.0001) and the first post-operative and most recent LM (p < 0.0001). There was no significant difference noted between the pre-operative LM score and most recent LM score (p = 0.14). CONCLUSION Despite concerns regarding possible subsequent development of chronic rhinosinusitis following endoscopic skull base surgery in pediatric patients, the current study suggests that transient radiographic evidence of sinus inflammation can be seen up to six months postoperatively, which appears to resolve by approximately two years after surgery.

Abstract
OBJECTIVE To evaluate the influence of facility case volume and type on skull base chordoma treatment and overall survival (OS). METHODS The 2004-2016 National Cancer Database was queried for skull base chordoma patients receiving definitive treatment. Facilities were categorized into 2 cohorts by calculating the mean number of patients treated per facility and using cutoff numbers that were 0.5 SD above and below the computed mean to separate the groups. As, by definition of the inclusion criteria, all included facilities treated at least 1 patient, low-volume facilities were defined as treating 1 patient, and high-volume facilities were defined as treating ≥7 patients; mid-volume facilities (facilities treating ≥2 but ≤6 patients) were excluded. Differences in treatment course, outcomes, and OS by facility type were assessed. RESULTS The study included 658 patients (44.8% female, 79.5% White). The 187 unique facilities were categorized into 95 low-volume facilities (treating 1 patient during timeline) and 26 high-volume facilities (treating ≥7 patients during timeline). Kaplan-Meier log-rank analysis demonstrated a significant positive association between facility volume and OS (P < 0.001) and an improvement in OS in patients at academic facilities (P = 0.018). On Cox proportional hazards multivariate regression after adjusting for sex, age, Charlson-Deyo comorbidity index, and insurance type, high-volume facilities and academic facilities were associated with a lower mortality risk than low-volume facilities and nonacademic facilities (P < 0.001 and P = 0.03, respectively). CONCLUSIONS Higher facility case volume and academic facility type appear to be associated with improved survival outcomes in treatment of skull base chordomas.

Abstract
Background Chronic rhinosinusitis (CRS) and eosinophilic esophagitis (EoE) are immune-mediated inflammatory conditions that share common histopathologic features. Once considered two separate pathologies, preliminary data has suggested that a higher prevalence of EoE may exist in patients with CRS. Objectives We aimed to expand the base of evidence across geographic regions and investigate the association between EoE and CRS, including CRS with nasal polyposis (CRSwNP). Methods Quantitative data detailing the prevalence of CRS, CRSwNP, and EoE were pooled from 6 large academic institutions spread across the United States using Epic electronic medical record system. One-way analysis of variance was then used to analyze the data. Results The mean prevalence of EoE in our general population sample of over 26 million individual records was 0.058% (range, 0.013%-0.103%). The mean prevalence of EoE in our sub-populations of individual with diagnoses of CRS and CRSwNP was 0.43% (F(1,12) = [8.194], P = .01) and 0.84% (F(1,12) = [23.61], P < .01) respectively. Conclusion This study reveals an 8-fold greater prevalence of concurrent EoE in patients with CRS. Importantly, this is the first study to describe the association of EoE and the CRSwNP subtype, and we demonstrate a 14-fold greater prevalence of EoE in patients with CRSwNP.

Abstract
BACKGROUND Chondrosarcomas of the sinonasal cavity and skull base are uncommon malignancies. We sought to provide long-term outcomes at two tertiary care centers. METHODS Patients with chondrosarcoma treated between 2000 and 2021 were included. The primary outcomes were overall survival (OS) and disease-specific survival (DSS). RESULTS Thirty-eight patients met inclusion criteria. Fourteen patients had sinonasal (36.8%), 7 petroclival (18.4%), and 17 other primary skull base lesions (44.7%). Twenty-eight patients (73.7%) underwent radiation with an average dose of 67.3 ± 15.1 Gy. Eighteen patients (47.4%) required revision surgery for recurrence. 1, 5, and 10-year OS were 97.3%, 93.1%, and 74.7%. DSS at 5- and 10-year survival was 95.7%. Adjuvant radiation was associated with improved OS (HR: 0.12; 95% CI: 0.02-0.75, p = 0.023). CONCLUSION We present our experience over the last 20 years treating chondrosarcomas. Favorable survival outcomes can be achieved but recurrence requiring repeat resection is common.

Abstract
BACKGROUND Hospital volume has emerged as a prognostic factor in oncology but is not currently known whether volume is associated with improved outcomes for cutaneous head and neck (HN) melanoma. METHODS A total of 556 079 cutaneous melanoma cases reported by the 2004-2016 National Cancer Database were separated into two cohorts (HN and non-HN) and facilities within each cohort were classified by case volume. Analysis employed chi-square, analysis of variance, Kaplan-Meier, and Cox proportional hazards models. RESULTS Only 41 facilities (3.1% of 1326) treating HN melanoma and 50 facilities (3.7% of 1344) treating non-HN melanoma were classified as high-volume facilities (HVFs). The estimated 5-year overall survival (OS) was 62.7% (standard error [SE]: 0.4%) for patients with HN at low-volume facilities (LVFs), 69.3% (SE: 0.4%) at IVFs, and 71.8% (SE 0.4%) at HVFs (p < 0.001). Differences in OS remained significant between HVFs versus LVFs after adjusting for confounders. CONCLUSION Volume is independently associated with OS and improved surgical outcomes for HN melanoma.

Abstract
Knowledge of chronic rhinosinusitis (CRS) epidemiology may directly impact patient care: aiding patient identification and establishing accurate diagnosis as well as informing treatment decisions. The objective of this review is to summarize the current evidence on the epidemiology of CRS, with a focus on prevalence and risk factors. Although the presence of either symptoms or objective findings alone have yielded CRS prevalence estimates of over 10%, the presence of both-consistent with guideline-based diagnostic criteria for CRS-has suggested that the true prevalence of CRS is consistently less than 5%, with approximately one-third of patients with CRS having nasal polyps, in epidemiologic studies from around the world. In comparison, the prevalence of CRS endotypes-pathophysiologic subclassification of CRS most commonly as related to type 2 or non-type 2 inflammation-has been found to vary significantly by region. The epidemiology of CRS is modified and ultimately determined by risk factors: genetic/hereditary, demographic, environmental, and imparted by predictive pre-/comorbid disease. The understanding of these epidemiologic relationships may help the provider to optimally identify and understand each individual's CRS disease process, thereby improving both diagnosis and treatment.

Abstract
OBJECTIVE Pain control is an important topic that has not been extensively studied in patients undergoing endoscopic skull base surgery (ESBS). The purpose of this study is to identify opioid requirements after ESBS and the risk factors predictive of increased use. METHODS This study was a retrospective review of all patients undergoing ESBS at a tertiary academic skull base surgery program between July 2018 and August 2020. The primary outcome variable was total morphine equivalent dose (MED) requirements after surgery, calculated as the sum of all morphine milligram equivalents over a 24-h period, and summated across the duration of each participant's hospital course. RESULTS 94 patients were included in this review. Average daily MED requirements were 14.00 ± 6.79 mg. Average total MED requirements were 83.78 ± 92.99 mg during hospitalization. Average length of stay (LOS) was 5.71 ± 4.42 days, with 22 (23.4%) patients not requiring opioid use upon discharge. On multivariate analysis, female sex (β = 49.62; 95% CI [13.53, 85.71], p = 0.008), nasoseptal flap (NSF) reconstruction (β = 49.56; 95% CI [13.51, 85.61], p = 0.008) and LOS (β = 4.02; 95% CI [0.001, 8.04], p = 0.050) were independently associated with higher total MED requirements. CONCLUSIONS We report average total MED requirements of 83.78 mg after ESBS, with female sex, intraoperative use of an NSF, and increased LOS as predictors of higher MED use. This data indicates a subset of patients who may benefit from more aggressive pain control strategies upfront, including consideration of non-opioid, multimodal pain regimens.

Abstract
OBJECTIVES The use of video recording is commonplace in rhinology given the increased use of endoscopes when evaluating patients in the office and the operating room and for its educational potential. This study aimed to determine the quality of publicly available endoscopic videos in rhinology. METHODS A video search was performed on YouTube in April 2020 and included all videos since its inception in 2005 using terms related to rhinology found in the Accreditation Council for Graduate Medical Education (ACGME) Case Log Coding Guide. Videos which met inclusion criteria were evaluated for video metrics and quality using validated scoring systems: Video Power Index (VPI), modified Journal of American Medical Association (JAMA) benchmark criteria, modified global quality score (GQS), and modified DISCERN criteria. RESULTS A total of 138 videos were evaluated, 114 of which were uploaded independently, and 24 videos were uploaded by an academic institution. Academic-affiliated videos have higher like ratio at 91.7 ± 7.55% compared with 86.27 ± 17.44% (p = 0.018). Academic-affiliated videos have higher JAMA benchmark scores, DISCERN criteria scores, and GQS values (1.71 ± 0.55 vs. 1.66 ± 0.49 [p = 0.66]), (3.33 ± 0.56 vs. 2.85 ± 0.65 [p < 0.001]), (4.38 ± 0.81 vs. 3.43 ± 1.01 [p < 0.001])], respectively. There was no significant difference in VPI (p = 0.73). CONCLUSIONS Endoscopic videos are rapidly growing in prominence and remain an important part of surgical education, but overall are heterogeneous in quality and reliability, necessitating an effort to establish both video sharing regulations and objective standards of quality.

Abstract
OBJECTIVES/HYPOTHESIS The objective of this study is to evaluate the impact of patient and surgical factors, including approach and reconstruction type, on postoperative nausea and vomiting episodes following endoscopic skull base surgery. STUDY DESIGN Retrospective review. METHODS We performed a retrospective chart review from July 2018 to August 2020 of 99 consecutive patients undergoing endoscopic skull base surgery at a tertiary academic skull base surgery program. All patients were treated with a standardized postoperative protocol consisting of scheduled ondansetron, along with promethazine and scopolamine for breakthrough nausea and vomiting episodes. Cumulative nausea and vomiting episodes throughout hospital stay were recorded for each patient. RESULTS Of the 99 patients identified, the mean number of nausea and vomiting episodes per patient were 0.4 ± 1.2 and 0.3 ± 0.7, respectively. Female sex (β = .65, P = .034) and extended surgical approach (β = .90, P = .027) were associated with increased risk for postoperative nausea. Furthermore, female sex (β = .44, P = .018), cavernous sinus dissection (β = .52, P = .002), and extended approach (β = .79, P = .025) significantly increased odds of postoperative vomiting episodes. There was no association between total operative time or total postoperative opioid dose and nausea and vomiting episodes (all Ps > .05). Neither increased nausea nor vomiting episodes significantly increased odds of prolonged hospitalization (P = .105 and .164, respectively). CONCLUSION This report highlights novel risk factors for patients undergoing endoscopic skull base surgery. Upfront standing antiemetic therapy may be considered when treating patients with independent predictors of postoperative nausea and vomiting, including female sex, cavernous sinus dissection, and extended surgical approach.

Abstract
BACKGROUND Early identification of fungal sinusitis remains a challenge. Previously, we observed a high false negative rate of using A-mode ultrasound to diagnose maxillary fungal sinusitis. This study aims to assess the accuracy of the diagnosis of fungal maxillary sinusitis using sinus plain film and ultrasound. METHODS The screening criteria is defined as the combination of a positive sinus plain film and a false negative sinus ultrasound. We retrospectively reviewed preoperative imaging of patients with fungal sinusitis and unilateral bacterial sinusitis of the maxillary sinus undergoing functional endoscopic sinus surgery from May 2013 to December 2019 in our hospital and evaluated the diagnostic performance of this screening method. RESULTS Forty-eight patients were included. Twenty-two and 26 patients were diagnosed with fungal sinusitis and bacterial sinusitis, respectively. Sixteen patients (72.7%) with fungal sinusitis presented with a false negative sinus ultrasound and met our screening criteria for fungal sinusitis. The screening criteria reached significance in the receiver operating characteristic curve analysis (p < 0.001). The area under the curve was 0.829. The sensitivity, specificity, and accuracy are 72.7%, 93.2%, and 88.4%, respectively. CONCLUSION A high false negative rate of sinus ultrasound in patients with fungal sinusitis was found. A positive sinus plain film combined with a false negative sinus ultrasound can potentially become an easy and cost-effective screening tool for diagnosing fungal maxillary sinusitis before consideration of computed tomography scanning.

Abstract
Objectives Skull base chordomas are locally aggressive malignant tumors derived from the notochord remnant. There are limited large-scale studies examining the role and extent of surgery and radiation therapy. Design Analysis of the National Cancer Database (NCDB) was performed to evaluate the survival outcomes of various treatments, and to assess for predictors of overall survival (OS). Participants This is a retrospective, population-based cohort study of patients diagnosed with a clival/skull base chordoma between 2004 and 2015 in the NCDB. Main Outcome Measures The primary outcome was overall survival (OS). Results In all, 468 cases were identified. Forty-nine percent of patients received surgery and 20.7% had positive margins. Mean age at diagnosis was 48.4 years in the surgical cohort, and 55% were males. Of the surgical cohort, 33.8% had negative margins, 20.7% had positive margins, and 45.5% had unknown margin status. Age ≥ 65 (hazard ratio [HR]: 3.07; 95% confidence interval [CI]: 1.63-5.76; p < 0.001), diagnosis between 2010 and 2015 (HR: 0.49; 95% CI: 0.26-0.90; p = 0.022), tumor size >5 cm (HR: 2.29; 95% CI: 1.26-4.15; p = 0.007), and government insurance (HR: 2.28; 95% CI: 1.24-4.2; p = 0.008) were independent predictors of OS. When comparing surgery with or without adjuvant radiation, no survival differences were found, regardless of margin status ( p = 0.66). Conclusion Surgery remains the mainstay of therapy. Advanced age (>65 years), large tumor size, and government insurance were predictors of worse OS. Whereas negative margins and the use of adjuvant radiation did not appear to impact OS, these may very well reduce local recurrences. A multidisciplinary approach is critical in achieving optimal outcomes in this challenging disease.

Abstract
Long-term survival and recurrence patterns of squamous cell carcinoma arising from inverted papilloma (IP-SCC) have not been thoroughly investigated. Four electronic databases were searched and primary studies describing overall survival (OS), recurrence, and mean time to recurrence of patients with IP-SCC were included for review. Our search yielded 662 studies. The 28 studies selected for inclusion identified 663 patients with IP-SCC. In 596 patients with reported T classification, 439 (73.7%) were T3/T4 on presentation. Of the 650 participants with recurrence data (local, regional, and distant), 155 (23.8%) experienced a recurrence, with an aggregate mean time-to-recurrence of 24.3 months. In 565 patients with 5-year OS rates, the aggregate 5-year OS was 62%. Based on the literature to date, IP-SCC is associated with a 5-year OS rate of 62%. 23.8% of patients experienced recurrence at a mean time of 24.3 months, suggesting the need for long-term surveillance.

Abstract
Pituitary adenoma is one of the three most common neoplasms described in multiple endocrine neoplasia type 1 (MEN1), and patients with pituitary adenoma occupies 30-50% of those with MEN1-related tumor. Mixed gangliocytoma-pituitary adenoma (MGPA) is a rare clinical entity in which gangliomatous cells are intermixed with adenomatous cells. This tumor has been estimated to account for 0.52-1.26% of all pituitary tumors. We report a rare case of MGPA in a patient with MEN1. A retrospective chart review was conducted on a patient with MEN1 diagnosed with MGPA in 2019 at a single tertiary academic medical center. A review of the literature was performed on MGPA and pituitary adenoma in MEN1. MGPA is rare, with only 174 cases previously reported in the literature and only three prior case reported in a patient with MEN1. There are multiple hypotheses regarding their pathogenesis, and it is unclear whether the MEN1 gene (menin) plays a role in the pathogenesis of MGPA. This tumor in MEN1 is a rare clinical entity of unknown etiology. Further studies are required with difficulty due to its low incidence.

Abstract
OBJECTIVE To determine the implications of obesity on postoperative adverse events following skull base surgery. METHODS The 2005-2017 American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried for adverse events in skull base surgery cases. Patients were stratified by body mass index (BMI) into normal weight (18.5 ≤ BMI < 25), overweight (25 ≤ BMI < 30), and obese (BMI ≥ 30) cohorts. Logistic regression was used to assess the association of overweight or obese BMI with various 30-day postoperative adverse events. RESULTS A total of 2305 patients were included for analysis, of which 732 (31.8%) and 935 (40.6%) were overweight or obese, respectively. The mean age was 53.8 ± 15.3 years and 1214 (52.7%) patients were female. Obese patients were younger (P = .033) and possessed higher frailty (P < .001) and ASA scores (P < .001). Operation times and lengths of hospitalization were not significantly different across patient cohorts (all P > .05). On propensity score-adjusted multivariable analysis, only bleeding (OR = 0.42, P < .001) and deep vein thrombosis (OR = 6.46, P = .015) were significantly associated with obesity. There were no significant differences in rates of readmission, reoperation, or mortality between normal weight and obese patients (all P > .05). CONCLUSIONS Obesity was associated with decreased postoperative bleeding and increased deep vein thromboses. Obese patients were otherwise at no higher risk for medical or surgical complications. Elevated BMI did not confer an increased risk for readmission, reoperation, or death. Thus, patient obesity should not be a major determinant in offering skull base surgery in individuals who would otherwise benefit from treatment.

Abstract
OBJECTIVE Chondrosarcomas of the skull base are rare tumors most commonly treated surgically with or without adjuvant radiation therapy. Using the National Cancer Database (NCDB), we analyzed overall survival (OS), treatment modalities, and prognosticators. METHODS The NCDB was queried for all cases of histologically confirmed skull base chondrosarcoma treated between 2004 and 2015, excluding patients with more than 1 malignant tumor, on palliative care, receiving unrelated concurrent treatments, or having less than 1 month of follow-up. The χ2 test for categorical variables, Cox proportional hazards models, and Kaplan-Meier log-rank analysis were used to test associations with the use of adjuvant radiation, OS, and survival time. RESULTS A total of 498 patients with skull base chondrosarcoma were identified in the NCDB. Of them, 224 (45.0%) and 198 (39.8%) were treated with either surgery alone or surgery with adjuvant radiation therapy, respectively. Patients more likely to undergo surgery with adjuvant radiation had higher tumor grade (P = 0.008), later year of diagnosis (P = 0.002), positive surgical margins (P < 0.001), and treatment at an academic institution (P = 0.02). Patient, tumor, and socioeconomic factors associated with worse OS on multivariate analysis included the Charlson/Deyo Comorbidity Score ≥2 (P = 0.017), as well as clear cell (P = 0.02) and dedifferentiated (P = 0.006) histology. Age, tumor grade, tumor size, treatment modality, insurance status, facility type, and urban/rural population did not show a statistically significant impact on OS. CONCLUSION The mainstay of treatment for skull base chondrosarcoma is surgery, with consideration of adjuvant radiation. This study demonstrated worse overall survival associated with more frail patients and aggressive histology types. It is important to consider these factors when planning the clinical management of these patients.

Abstract
BACKGROUND Studies have suggested that physicians are steadily being paid less per Medicare service over time based on inflation-adjusted dollars. The objective of this study was to determine whether this phenomenon was true for rhinologic procedures. METHODS This study was a retrospective analysis of the 2000-2021 Centers for Medicare & Medicaid Services (CMS) Physician Fee Schedule investigating fees for in-office endoscopies (Current Procedural Terminology [CPT] codes 31231-31238), in-office balloon ostial dilation (CPTs 31295-31298), in-facility low-relative value unit (RVU) surgeries (<10 work RVUs [wRVUs]; CPTs 31239-31288 and 61782), and in-facility high-RVU surgeries (>10 wRVUs; CPTs 31290-31294). Total number of and reimbursements for these services was obtained from yearly National Part B Summary Datafiles. RESULTS Between 2000 and 2021, adjusted reimbursements for low- and high-wRVU rhinologic surgeries decreased by 50.0% and 36.1%, respectively. The average compound annual growth rate (CAGR) decrease was 3.3% and 2.1%, respectively. Excluding a 48.3% unadjusted reimbursement increase between 2000 and 2004, endoscopies saw an adjusted reimbursement decrease of 29.4% from 2004 onward, an average CAGR of -2.1%. From 2011 onward, balloon ostial dilations saw a decrease in adjusted reimbursement of 43.8%, an average CAGR of -6.0%. Nevertheless, after inflation adjustment, National Part B data reveal that Medicare paid more, in total, for these procedures in 2019 than in 2000 due to increasing utilization. CONCLUSION Medicare reimbursements are complex, adjusted yearly, and undergo constant federal scrutiny due to the increasing costs of health care. These results suggest that, in terms of real dollars, rhinologic procedures have seen a large gradual decrease in Medicare reimbursement, which is important information for policymakers and surgeons alike.

Abstract
Background No study to date has analyzed the progression of sinonasal symptoms over time in COVID-19 patients. The purpose of this study is to analyze the progression of sinonasal symptoms and risk factors for olfactory dysfunction in the mild severity COVID-19 patient. Methods An internet survey was used to assess sinonasal symptoms in patients with COVID-19. Changes in rhinologic domain and symptom-specific Sinonasal Outcome Test (SNOT-22) scores were compared at five time points: two weeks before diagnosis, at diagnosis, two weeks after diagnosis, four weeks after diagnosis, and six months after diagnosis. Results 521 responses were collected. Rhinologic domain SNOT-22 scores increased significantly (p < 0.001) to 8.94 at the time of diagnosis, remained elevated two weeks post-diagnosis (5.14, p = 0.004), and decreased significantly four weeks post-diagnosis (3.14, p = 0.004). Smell-specific SNOT-22 scores peaked at the time of diagnosis (2.05, p < 0.001), remained elevated two weeks after diagnosis (1.19, p < 0.001), and returned to baseline four weeks post-diagnosis (0.64, p > 0.999). Taste-specific SNOT-22 scores also peaked at diagnosis (2.06, p < 0.001), remained elevated two weeks after diagnosis (1.19, p < 0.001), and returned to baseline four weeks after diagnosis (0.71, p > 0.999). There were no significant differences in sense of smell or taste between 1-month and 6-month timepoints. Conclusion Sinonasal symptoms, particularly loss of smell and taste, may be important presenting symptoms in the mild severity COVID-19 patient. Our findings support incorporating these symptoms into screening protocols. Level of evidence: 4

Abstract
OBJECTIVE Suprasellar meningioma resection via either the transcranial approach (TCA) or the endoscopic endonasal approach (EEA) is an area of controversy and active evaluation. Skull base surgeons increasingly consider patient-reported outcomes (PROs) when choosing an approach. No PRO measure currently exists to assess quality of life for suprasellar meningiomas. METHODS Adult patients undergoing suprasellar meningioma resection between 2013 and 2019 via EEA (n = 14) or TCA (n = 14) underwent semistructured interviews. Transcripts were coded using a grounded theory approach to identify themes as the basis for a PRO measure that includes all uniquely reported symptoms. To assess content validity, 32 patients and 15 surgeons used a Likert scale to rate the relevance of items on the resulting questionnaire and the general Patient-Reported Outcomes Measurement Information System-29 (PROMIS29). The mean scores were calculated for all items and compared for TCA versus EEA patient cohorts by using unpaired t-tests. Items on either questionnaire with mean scores ≥ 2.0 from patients were considered meaningful and were aggregated to form the novel Suprasellar Meningioma Patient-Reported Outcome Survey (SMPRO) instrument. RESULTS Qualitative analyses resulted in 55 candidate items. Relative to patients who underwent the EEA, those who underwent the TCA reported significantly worse future outlook before surgery (p = 0.01), tiredness from medications 2 weeks after surgery (p = 0.001), and word-finding and memory difficulties 3 months after surgery (p = 0.05 and < 0.001, respectively). The items that patients who received a TCA were most concerned about included medication-induced lethargy after surgery (2.9 ± 1.3), blurry vision before surgery (2.7 ± 1.5), and difficulty reading due to blurry vision before surgery (2.7 ± 2.7). Items that patients who received an EEA were most concerned about included blurry vision before surgery (3.5 ± 1.3), difficulty reading due to blurry vision before surgery (2.4 ± 1.3), and problems with smell postsurgery (2.9 ± 1.3). Although surgeons overall overestimated how concerned patients were about questionnaire items (p < 0.0005), the greatest discrepancies between patient and surgeon relevance scores were for blurry vision pre- and postoperatively (p < 0.001 and < 0.001, respectively) and problems with taste postoperatively (p < 0.001). Seventeen meningioma-specific items were considered meaningful, supplementing 8 significant PROMIS29 items to create the novel 25-item SMPRO. CONCLUSIONS The authors developed a disease- and approach-specific measure for suprasellar meningiomas to compare quality of life by operative approach. If demonstrated to be reliable and valid in future studies, this instrument may assist patients and providers in choosing a personalized surgical approach. ABBREVIATIONS EEA = endoscopic endonasal approach; GTR = gross-total resection; PRO = patient-reported outcome; PROMIS29 = Patient-Reported Outcomes Measurement Information System-29; QOL = quality of life; SMPRO = Suprasellar Meningioma Patient-Reported Outcome Survey; TCA = transcranial approach.

Abstract
OBJECTIVE Inverted papilloma (IP) is the most common benign neoplasm of the nasal cavity with known risk of recurrence. There is no standardized approach to definitive treatment for attachment sites. This systematic review aims to determine whether surgeon choice of technique differs by anatomic attachment site and whether different surgical techniques contribute to reduced rates of recurrence. DATA SOURCES PubMed and Ovid Medline. REVIEW METHODS A systematic review was conducted for studies reporting on IP. Those that included IP recurrence rates and primary tumor attachment site were reviewed. RESULTS Of 122 published studies, 14 met eligibility criteria, representing 585 patients and a recurrence rate of 5.8%. The maxillary sinus (50.9%) was the most common primary attachment site, and the sphenoid sinus was associated with the highest rate of recurrence (10.4%). The most utilized technique included debulking the tumor, removing mucosa over the attachment site, and drilling the underlying bone. The most common Krouse stage represented was T3 (53.3%). No single technique predicted a propensity for recurrence, but certain techniques are favored depending on IP attachment site. Finally, frozen sections to obtain evidence of clear margins intraoperatively significantly reduced rates of recurrence (3.4% vs 7.3%, P = .045). CONCLUSION Based on the current literature, the most common technique to address site of attachment involves resecting mucosa and drilling the tumor base. Choice of technique appears to differ for various sites of attachment. Use of intraoperative frozen section analysis appears to be associated with decreased recurrence overall. LEVEL OF EVIDENCE 3.

Abstract
BACKGROUND Spindle cell oncocytoma (SCO) of the pituitary gland is an extremely rare nonfunctional World Health Organization grade I tumor. SCOs are often misdiagnosed as nonfunctional pituitary adenomas on the basis of preoperative imaging. They are often hypervascular and locally adherent, which increases hemorrhage risk and limits resection, leading to increased risk of recurrence. The authors report a case of SCO treated at their institution and provide a review of the current literature. OBSERVATIONS SCO of the pituitary gland can be a rare cause of progressively growing pituitary tumors that presents similarly to nonfunctional pituitary adenoma. Endoscopic transsphenoidal resection of the tumor by a multidisciplinary team allowed total resection despite local adherence of the tumor. Postoperatively, the patient’s visual symptoms improved with persistence of secondary adrenal insufficiency and secondary hypothyroidism. LESSONS Careful resection is needed due to SCO’s characteristic hypervascularity and strong adherence to minimize local structure damage. Long-term follow-up is recommended due to the tendency for recurrence.

Abstract
OBJECTIVE Pituitary adenomas in the pediatric population are extremely rare, resulting in limited information in the literature on these patients. In this study, data from the National Cancer Database (NCDB) to compare pituitary adenoma clinical presentations, treatment management patterns, and overall survival between pediatric and adult patients. METHODS The NCDB was queried for all cases of histologically confirmed pituitary adenoma treated between 2004 and 2015. Patients were primarily stratified as either pediatric (< 18 years) or adult (≥ 18 years). Patient demographics/socioeconomics and resulting outcomes were then compared. RESULTS 1893 pediatric and 77,993 adult patients with pituitary adenomas were evaluated. Average tumor size for pediatric and adult patients was 13.6 ± 13.2 mm and 20.1 ± 13.1 mm, respectively (p < 0.001). Pediatric patients were more likely to undergo gross total resection, less likely to receive adjuvant radiation, more likely to receive medical therapy, more likely to undergo active surveillance, and exhibited improved 5-year and 10-year overall survival (OS) (all p < 0.001). Temporal analysis demonstrated a significant increase in endoscopic approach over time (from 48 to 65%) in the pediatric population (R2 = 0.722, p = 0.03). On univariate analysis in the pediatric population, African American race compared to Caucasians (HR: 5.85, 95% CI 1.79-19.2, p < 0.003), patients with government insurance compared to those with private insurance (HR: 5.07, 95% CI 1.31-19.6, p < 0.02) and uninsured patients compared to those with private insurance (HR: 14.4, 95% CI 2.41-86.5, p < 0.003) were associated with decreased OS. Lastly, patients who underwent GTR had improved OS compared to those who underwent subtotal resection (HR: 0.08, 95% CI 0.008-0.93, p < 0.04) in the pediatric population. CONCLUSIONS Compared to adults, children with pituitary adenomas more commonly underwent GTR, less frequently underwent adjuvant radiotherapy, more frequently underwent medical management and active surveillance, and had improved survival. Temporal analysis demonstrated increasing utilization of the endoscopic approach for surgical treatment of pediatric and adult pituitary adenoma patients. LEVEL OF EVIDENCE Level III.

Abstract
Background Nasopharyngeal swab testing, which has greatly increased in utilization due to the COVID-19 pandemic, is generally safe and well-tolerated, although it may be rarely associated with adverse events. Methods Publicly reported adverse events associated with nasopharyngeal COVID-19 testing within the Manufacturer and User Facility Device Experience (MAUDE) database and the published literature were queried. Results A total of 129 adverse events were reported, including 66 from the MAUDE database and 63 from literature review. The most common complications were swab fracture resulting in retained foreign body (47%), followed by epistaxis (17%), and headache (11%). Seven (12%) of the reported retained foreign body cases required removal under general anesthesia, while 1 (5%) of the epistaxis cases required surgical intervention. The most serious adverse event was meningitis following cerebrospinal fluid leak. Conclusions Patients and healthcare providers should be aware of the potential risks associated with testing, with attention to ensuring proper technique, and be prepared to recognize and manage adverse events.

Abstract
OBJECTIVES/HYPOTHESIS This study offers an update on the epidemiologic and prognostic factors and treatment-specific outcomes in patients diagnosed with sinonasal diffuse large B-cell lymphoma (DLBCL). STUDY DESIGN Retrospective cohort study. METHODS National Cancer Database was queried from 2004 to 2016 for patients with sinonasal DLBCL. Univariate Kaplan-Meier and multivariate Cox-regression analyses were performed to evaluate the association of suspected prognostic factors with overall survival (OS). RESULTS A total of 2,222 patients with sinonasal DLBCL were analyzed. OS was 62% at 5 years and 42% at 10 years. Prognostic factors associated with increased survival included African-American race (HR: 0.48, 95% CI: 0.33-0.70), chemotherapy (HR: 0.30, CI: 0.25-0.35), and radiation (HR: 0.80, CI: 0.69-0.93). Prognostic factors associated with decreased survival included patients with Charlson-Deyo scores of 1 (HR: 1.51, CI: 1.25-1.84), 2 (HR: 2.25, CI: 1.67-3.03), and 3 (HR: 2.36, CI: 1.49-3.74) and patients with Lugano stage III (HR: 1.69, CI: 1.09-2.62) and IV (HR: 1.96, CI: 1.46-2.64) disease. Stage-based split multivariate analysis was performed and revealed chemotherapy was independently associated with increased OS in patients with stage I (HR: 0.24, CI: 0.19-0.30), II (HR: 0.17, CI: 0.11-0.28), and IV (HR: 0.41, CI: 0.26-0.64) disease. Radiotherapy was independently associated with increased OS in patients with stage I disease only (HR: 0.67, CI: 0.55-0.83), while immunotherapy was an independent prognostic factor in patients with stage IV disease only (HR: 0.60, CI: 0.37-0.98). CONCLUSION This study is the largest to date to analyze the association of demographic features and treatment modalities with OS in patients with sinonasal DLBCL. It is the first to investigate the association of immunotherapy with OS in this population. A combination treatment of immunochemotherapy or radioimmunochemotherapy confers increased survival, particularly in patients with advanced disease. LEVEL OF EVIDENCE IV Laryngoscope, 2021.
