The management of clival chordoma in our group shifted around 2013 to mostly endoscopic, and proton beam was introduced for our multidisciplinary team. Consecutive patients who had surgical resection from 1987 to 2021 were reviewed. A total of 58 patients (39 patients after 2013) were analyzed. The mean tumor size was 3.7 cm, and the most common location was the upper clivus (43%). Compared to before 2013, after 2013, the endoscopic endonasal approach was more common (90%, p < 0.001), and more gross or near total resections (64%, p = 0.002) were attained. Ten cases (17%) were revision surgeries referred from elsewhere, and three cases (5%) underwent additional surgery elsewhere before adjuvant radiation. The postoperative cerebrospinal fluid leak occurred in 7%. Post-operative new cranial nerve deficits occurred in 32% before 2013, compared to 2.6% after 2013 (p = 0.004). For cases before 2013, 10 patients (53%) recurred during the median follow-up of 144 months (mean, 142 months), whereas for cases after 2013, seven patients (18%) recurred with a median follow-up of 35 months (mean, 42 months). 5-year progression-free survival was 58%, and 5-year overall survival was 87%. A specialized multidisciplinary team improved the resection rate compared to a historical cohort with an excellent morbidity profile.

Abstract Background The literature regarding clinical olfaction, olfactory loss, and olfactory dysfunction has expanded rapidly over the past two decades, with an exponential rise in the past year. There is substantial variability in the quality of this literature and a need to consolidate and critically review the evidence. It is with that aim that we have gathered experts from around the world to produce this International Consensus on Allergy and Rhinology: Olfaction (ICAR:O). Methods Using previously described methodology, specific topics were developed relating to olfaction. Each topic was assigned a literature review, evidence‐based review, or evidence‐based review with recommendations format as dictated by available evidence and scope within the ICAR:O document. Following iterative reviews of each topic, the ICAR:O document was integrated and reviewed by all authors for final consensus. Results The ICAR:O document reviews nearly 100 separate topics within the realm of olfaction, including diagnosis, epidemiology, disease burden, diagnosis, testing, etiology, treatment, and associated pathologies. Conclusion This critical review of the existing clinical olfaction literature provides much needed insight and clarity into the evaluation, diagnosis, and treatment of patients with olfactory dysfunction, while also clearly delineating gaps in our knowledge and evidence base that we should investigate further.

Objective: To evaluate geographic and temporal trends in Medicare fee-for-service (FFS) billing and reimbursements across female otolaryngologists (ORL). Methods: We performed a cross-sectional, retrospective analysis of the 2017 Medicare Physician and Other Suppliers Aggregate File. We analyzed differences in the number of services, patients, reimbursements, unique Current Procedural Terminology (CPT) codes used, and services billed per patient among female ORLs. Results: Female ORLs accounted for 15.2% of the 8453 Medicare-reimbursed ORLs. Female ORLs who graduated between 2000 and 2010 were reimbursed a median of $58 031.9 (IQR: $32 286.5-$91 512.2) and performed a median of 702 (IQR: 359.5-1221.5) services, significantly less than those who graduated between 1990 and 1999 (median: $67 508.9; IQR: 37 018.0-110 471.5; P < .001; median: 1055.5; IQR: 497.3-1944; P < .001). Female ORLs who graduated between 2000 and 2010 saw a median of 232 patients (IQR: 130.5-368), significantly less than those who graduated between 1990 and 1999 (median: 308; IQR: 168.3-496; P < .001) patients, significantly more than those. Female ORLs in urban settings performed a median of 795 (IQR: 364-1494.3) services and billed for a median of 42 (IQR: 28-58) unique codes, significantly fewer than their counterparts in rural settings (median: 1096; IQR: 600-2192.5; P = .002; median: 54; IQR: 31.5-64.5; P = .001). Conclusions: Medicare reimbursements and billing patterns across female ORLs varied by graduation decade and geography. Female ORLs further along in their careers may be reimbursed more with greater clinical volume and productivity. Those practicing in urban settings may have practices with decreased procedural diversity and lower clinical volume compared to their counterparts in rural areas.

AbstractBackgroundSinonasal adenocarcinoma (SNAC) is a rare tumor. The impact of health disparities on survival, stage at presentation, and utilization of surgery is not well understood in patients with SNAC.MethodsThe Surveillance, Epidemiology, and End Results database was queried for cases of SNAC from 1973 to 2015. Cases were analyzed to assess for disparities in presentation, treatment, and survival.ResultsSNAC was identified in 630 patients. In a multivariate model of overall survival, an age increase of 10 years (Hazard Ratio (HR) = 1.37, p < 0.001), male sex (HR = 1.26, p = 0.045), and more recent decade of diagnosis (HR = 0.74, p < 0.001) were significantly related to time‐to‐death. There is a higher rate of SNAC‐related death in counties with more rural populations (p = 0.027).ConclusionFuture interventions targeting rural and less well‐educated populations may improve care with the goal of increasing the span of healthy life and reducing survival disparities related to SNAC.

Objective To provide a comprehensive state‐of‐the‐art review of the emerging role of urine leukotriene E4 (uLTE4) as a biomarker in the diagnosis of chronic rhinosinusitis (CRS), aspirin‐exacerbated respiratory disease (AERD), and asthma. Data Sources Ovid MEDLINE(R), Ovid EMBASE, Ovid Cochrane Central Register of Controlled Trials, Ovid Cochrane Database of Systematic Reviews, and Scopus. Review Methods A state‐of‐the‐art review was performed investigating the role of uLTE4 as a diagnostic biomarker, predictor of disease severity, and potential marker of selected therapeutic efficacy. Conclusions uLTE4 has been shown to be a reliable and clinically relevant biomarker for CRS, AERD, and asthma. uLTE4 is helpful in ongoing efforts to better endotype patients with CRS and to predict disease severity. Implications for Practice Aside from being a diagnostic biomarker, uLTE4 is also able to differentiate aspirin‐tolerant patients from patients with AERD and has been associated with objective disease severity in patients with CRS with nasal polyposis. uLTE4 levels have also been shown to predict response to medical therapy, particularly leukotriene‐modifying agents.

BackgroundA recent analysis suggested potential narrowing of the gender gap in research productivity in the field of rhinology. This analysis did not, however, provide insight into how the genders are represented in the rhinologic literature. This study aimed to evaluate 11 years of literature to evaluate for gender differences in authorship position, collaborations, category and content of research, citations, and funding to gain perspective on how gender and authorship has changed over time.MethodsAuthorship data for all articles on rhinologic subject matter published between January 1, 2008 and December 31, 2018 in four otolaryngology journals was collected. The gender of authors was determined by protocol. Category and content of research and funding status/source were additionally obtained.ResultsData were collected from 2666 articles. Gender of 14,510 authors was determined. Female authors accounted for 23% of the overall authors and male authors accounted for 77%. Female first authorship increased significantly over time, but there was no change in female senior authorship. The percentage of female authors steadily increased over time, whereas male authorship decreased slightly. Mixed gender teams were shown to be increasing in frequency. Women published more than expected in basic science and allergy and less than expected in skull base. On funded studies, women were significantly underrepresented as senior authors.ConclusionThis study represents the first assessment of gender differences in the rhinology literature. Areas where female representation can improve include senior authorship, increased involvement in skull base publications, and increased funding.

BackgroundAsthma and some chronic rhinosinusitis (CRS) subtypes are mediated by similar pathophysiologic mechanisms. The purpose of this study was to evaluate the effects of biologic therapy for asthma on co‐existent CRS in the “real‐world” setting.MethodsA review of electronic health records (2016‐2019) at Mayo Clinic was conducted to identify asthma patients treated with biologics who had co‐existent CRS. Matched‐pair analyses compared pretherapy and posttherapy Lund‐Mackay computed tomography (CT) scores and 22‐item Sino‐Nasal Outcome Test (SNOT‐22) scores. Performance of endoscopic sinus surgery (ESS) after initiating biologics was studied.ResultsWe identified 247 patients who received anti‐asthma biologic therapy and had co‐existent CRS. Of these, 181 patients (73.3%) had CRS with nasal polyposis (CRSwNP) and 66 (26.7%) had CRS without nasal polyposis (CRSsNP). The biologics utilized were omalizumab (51.0%), mepolizumab (46.6%), benralizumab (10.5%), reslizumab (1.6%), and dupilumab (2.4%). Anti‐interleukin‐5 (anti‐IL‐5) intervention was associated with significant improvement in CT scores (CRS overall, CRSwNP subgroup, CRSsNP subgroup) and SNOT‐22 scores (CRS overall, CRSwNP subgroup). Patients on omalizumab had a decrease in CT scores, but not SNOT‐22 scores. ESS was performed in 206 patients (84.1%); 55 (22.3%) underwent surgery post–biologic intervention (anti‐IL‐5: 16.5%; omalizumab 27.8% of patients).ConclusionAnti‐IL‐5 agents were associated with improved CT and SNOT‐22 scores in the overall CRS group and in CRSwNP subgroup; CRSsNP patients showed improved CT scores only. Omalizumab improved CT but not SNOT‐22 scores. ESS was performed in 22% of patients after initiating biologics. These real‐world results may influence future trial designs and clinical applications of biologics for CRS. ©2021 ARSAAOA, LLC.
