Endoscopic endonasal approach for olfactory groove meningioma resection: Strategies and outcomes in a retrospective case series.

OBJECTIVE: Though the endoscopic endonasal approach (EEA) is a widely accepted treatment for skull base tumors, the specific use of EEA for olfactory groove meningiomas (OGMs) is debated, with variable outcomes reported in the literature. We review the surgical results of OGM resections for one surgeon including the operative approach, surgical nuances, and outcomes, with a focus on factors relating to patient selection which favor EEA over transcranial approaches. METHODS: We retrospectively reviewed thirteen cases of endoscopic endonasal resection of olfactory groove meningiomas. Patient characteristics, clinical characteristics, surgical outcomes, and complications were analyzed. Extent of resection was determined based on volumetric analysis of pre- and postoperative MRI. RESULTS: Anatomic characteristics that render a tumor difficult to access fully are lateral extension beyond the mid-orbit and anterior extension to the falx. Simpson Grade I resection was achieved in 11/13 (84.6 %) cases. Mean pre-operative tumor volume was 8.99 cm3 (range 2.19-16.79 cm3), and 92 % of tumors were WHO grade I. We demonstrate 2 cases of smell preservation, possible with small unilateral tumors and tumors that are confined to either the anterior or posterior portion of the cribriform plate. The post-operative CSF leak rate was 7.7 %, without prophylactic lumbar CSF drainage. The mortality rate was 7.7 % (n = 1) after infectious complications following CSF leak. CONCLUSIONS: Endoscopic endonasal resection of olfactory groove meningiomas is an effective and safe operative method with outcomes and complication rates comparable to transcranial approaches. Key considerations include careful patient selection and familiarity with technical nuances of endoscopic endonasal approach for this specific tumor type.

Adverse events associated with budesonide nasal irrigation reported to the US Food and Drug Administration: 2007 to 2022.

KEYPOINTS: Between 2007 and 2022, the FDA received 119 US-based reports mentioning budesonide nasal irrigation. Most reports were submitted by patients and alerted FDA to off-label usage of budesonide. Notable adverse events reported to the FDA included headache, dyspnea, and blurred vision.

Trends of Odontogenic Sinusitis Incidence During the COVID-19 Pandemic.

OBJECTIVES: The COVID-19 pandemic affected the epidemiology of several diseases. This study aims to compare the incidence of surgically treated odontogenic sinusitis (ODS) before and during the COVID-19 pandemic and identify unique features. METHODS: A retrospective chart review of patients who underwent at least maxillary antrostomy at a tertiary referral center was performed. The patients were divided into two cohorts: "pre-COVID" (March 2018 to February 2020) and "COVID" (March 2020 to February 2022). Data on demographics, comorbidities, and treatment interventions were collected and analyzed. RESULTS: Of the 734 patients who underwent maxillary antrostomy, 370 (50.4%) were operated on during the COVID period, with a mean age of 53.1 ± 15.7 years. ODS was found as the etiology of 22 (6%) and 45 (12.2%) of the pre-COVID and COVID cases, respectively (p = 0.006). Although no difference was found in the incidence of diabetes (p = 0.9) or obesity (p = 0.7) between groups, a trend toward higher incidence of immunosuppression was found in the pre-COVID patients (18.2% vs. 0%, p = 0.06). A higher incidence of sphenoid sinus involvement (31.8% vs. 8.9%, p < 0.05) was identified in the pre-COVID group; however, no differences in ethmoid (86.4% vs. 86.7%, p = 0.999) or frontal sinus involvement (54.5% vs. 37.8%, p = 0.3) were found between the groups. CONCLUSION: There was an increase in the incidence of ODS during the first 2 years of the COVID-19 pandemic compared to the 2 years prior. Similar clinical characteristics were found in both groups. Future studies focusing on specific etiologies to explain ODS preponderance may help determine optimal treatment and prevention strategies. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:1597-1602, 2024.

Five-year EuroQol 5-Dimension Outcomes After Endoscopic Sinus Surgery.

OBJECTIVE: The EuroQol 5-Dimension (EQ-5D) is a general health survey that is quick to administer, widely used, and directly convertible to health utility values (HUV). We aim to describe the five-year EQ-5D outcomes among patients who undergo surgical treatment for chronic rhinosinusitis (CRS). STUDY DESIGN: Prospective observational cohort study. METHODS: Patients with CRS completed the EQ-5D questionnaire preoperatively and annually for five years following endoscopic sinus surgery. Paired t-tests and McNemar's tests were used to compare preoperative and postoperative scores. Mixed-effects modeling was used for multivariate analysis. RESULTS: Among 1296 patients enrolled in our study, 812 (74.7%) completed the postoperative survey at one year and 336 (38.9%) completed it at five years. There was a significant and sustained reduction of patients reporting pain/discomfort (74.9% vs. 58.0%, p < 0.001) and anxiety/depression (49.6% vs. 38.1%, p = 0.01) out to five years. Frequency of problems reported in the usual activity domain decreased at one year and was sustained through year four (30.6% vs 19.7%, p = 0.003). After multivariable modeling, female gender (p = 0.02), prior sinus surgery (p = 0.01), tobacco use (p = 0.038), headaches (p = 0.013), allergies (p = 0.001), diabetes (p = 0.022), hypertension (p = 0.036), higher preoperative SNOT-22 score (p < 0.001), and a lower preoperative Lund-Mackay score (p < 0.001) were associated with significantly worse EQ-5D HUV over time. Similarly, a worse EQ-5D Visual Analog Scale (VAS) over time was associated with allergies (p = 0.03), diabetes (p < 0.001), hypertension (p = 0.04), higher preoperative SNOT-22 score (p < 0.001), and prior sinus surgery (p < 0.001). CONCLUSION: Patients with chronic rhinosinusitis experience significant sustained improvements in health-related quality of life up to five years after ESS as measured by the EQ-5D instrument.

Competency-based medical education in the United States: What the otolaryngologist needs to know.

Competency-based medical education (CBME) is an outcomes-focused approach to educating medical professionals that will be central to future efforts to improve resident training in otolaryngology. The transition to CBME for otolaryngology in the United States will require the development of specialty-specific assessments and benchmarks, the financial and administrative support for implementation, the professional development of faculty and learners, and the cooperation of all major stakeholders in graduate medical education. In this article, we describe the need for evidence-based innovation in surgical training, the history of CBME in the United States, and the progress towards defining "entrustable professional activities" as the building blocks of assessments for CBME. We explore what such a paradigm shift in surgical education could mean for academic otolaryngologists by examining innovative educational practices in other surgical specialties and discussing foreseeable challenges in implementation for the American healthcare system.

Ear, Nose, and Throat Manifestations of Vasculitis and Other Systemic Autoimmune Diseases: Otologic, Sinus, and Airway.

Auricular, nasal, and laryngeal manifestations occur frequently in rheumatic diseases. Inflammatory ear, nose, and throat (ENT) processes often result in organ damage and have profound effects on quality of life. Herein, we review the otologic, nasal, and laryngeal involvement of rheumatic diseases, focusing on their clinical presentation and diagnosis. ENT manifestations generally respond to treatment of the systemic disease, which is outside the scope of this review; however, adjunctive topical and surgical treatment approaches, as well as treatment of idiopathic inflammatory ENT manifestations will be reviewed.

A paired curriculum for surgical faculty and residents on adult education.

A paired surgical educator curriculum on adult learning was designed for residents and faculty at a large otolaryngology residency program. In its first year of implementation, 12 core faculty and 20 residents attending the workshops, with positive feedback from all participants and measurable improvements in their understanding of basic terms in adult cognitive learning theory. The curriculum enabled faculty and residents to practice applying educational theories to their every day clinical teaching activities and is adaptable for use in other surgical training programs. Level of Evidence: IV.

Trends in price, spending, and utilization of omalizumab among Medicare beneficiaries.

KEY POINTS: Between January 2005 and January 2023, the average selling price of omalizumab increased by nearly 60%. Between 2016 and 2021, Medicare Part B and D spending on omalizumab totaled over $3.7 billion. Between 2016 and 2021, Medicare Part B and D utilization of omalizumab increased by approximately 30%.

A Practical Introduction to Growth Mindsets in Surgical Training.

This Viewpoint summarizes the research behind psychological mindsets and their possible applications to surgical training and introduces some practical recommendations to harness growth mindsets for optimizing the learning of otolaryngology residents.

The Impact of Gender on Long-Term Quality of Life After Sinus Surgery for Chronic Rhinosinusitis.

OBJECTIVE: To identify the impact of gender on the clinical outcomes of endoscopic sinus surgery (ESS) through the comparison of quality of life measures in female and male patients who undergo surgical treatment for chronic rhinosinusitis (CRS). STUDY DESIGN: Prospective observational cohort study. METHODS: Patients with CRS completed the 22-item Sino-Nasal Outcome Test (SNOT-22) and EuroQol 5-Dimension Survey (EQ-5D) preoperatively and annually for 5 years following ESS. Health utility values (HUV) were calculated from EQ-5D scores. Comparisons of cohort characteristics were performed with chi-square and t-tests. A multivariable linear mixed effects model evaluated changes in SNOT-22 and HUV over time by gender. RESULTS: Among the 1268 patients (54% female) enrolled, 789 and 343 completed postoperative surveys at one and 5 years, respectively. Preoperatively, females experienced more severe symptoms: mean SNOT-22 score (51.1 ± 20.9 female vs. 44.7 ± 20.0 male, p < 0.001) and HUV (0.80 ± 0.14 female vs. 0.84 ± 0.11 male, p < 0.001). These gender differences were resolved by year one postoperatively (SNOT-22: p = 0.083; HUV: p = 0.465). Two years after surgery, however, females reported more severe symptoms (SNOT-22: 25.6 ± 20.7 female vs. 21.5 ± 17.4 male, p = 0.005; HUV: 0.88 ± 0.12 female vs. 0.90 ± 0.11 male, p = 0.018), a difference that persisted at year five. These gender-related differences remained after adjusting for age, race, ethnicity, nasal polyps, history of prior ESS, and smoking status (p < 0.001). Within-subject improvement was comparable between genders (SNOT-22: p = 0.869; HUV: p = 0.611). CONCLUSION: Females with CRS reported more severe symptoms both before and 5 years after surgery compared to their male counterparts. Understanding the mechanism behind these gender-related differences is important for optimizing CRS treatment. LEVEL OF EVIDENCE: 2 Laryngoscope, 133:3319-3326, 2023.

Determinants of physician assessment of chronic rhinosinusitis disease control using EPOS 2020 criteria and the importance of incorporating patient perspectives of disease control.

BACKGROUND: We identify chronic rhinosinusitis (CRS) manifestations associated with how rhinologists assess CRS control, with a focus on patient perspectives (patient-reported CRS control). METHODS: Fifteen rhinologists were provided with real-world data from 200 CRS patients. Participating rhinologists first classified patients' CRS control as "controlled," "partly controlled," and "uncontrolled" using seven CRS manifestations reflecting European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) CRS control criteria (nasal obstruction, drainage, impaired smell, facial pain/pressure, sleep disturbance, use of systemic antibiotics/corticosteroids in past 6 months, and nasal endoscopy findings) and patient-reported CRS control. They then classified patients' CRS control without knowledge of patient-reported CRS control. Interrater reliability and agreement of rhinologist-assessed CRS control with patient-reported CRS control and EPOS guidelines were determined. RESULTS: CRS control classification with and without knowledge of patient-reported CRS control was highly consistent across rhinologists (κw  = 0.758). Rhinologist-assessed CRS control agreed with patient-reported CRS control significantly better when rhinologists had knowledge of patient-reported CRS control (κw  = 0.736 vs. κw  = 0.554, p < 0.001). Patient-reported CRS control, nasal obstruction, drainage, and endoscopy findings were most strongly associated with rhinologists' assessment of CRS control. Rhinologists' CRS control assessments weakly agreed with EPOS CRS control guidelines with (κw  = 0.529) and without (κw  = 0.538) patient-reported CRS control. Rhinologists classified CRS as more controlled than EPOS guidelines in almost 50% of cases. CONCLUSIONS: This study directly demonstrates the importance of patient-reported CRS control as a dominant influence on rhinologists' CRS control assessment. Knowledge of patient-reported CRS control may better align rhinologists' CRS control assessments and treatment decisions with patients' perspectives.

Predicting Resident Competence for Otolaryngology Key Indicator Procedures.

OBJECTIVE: Competency-based surgical education requires practical assessments and meaningful benchmarks. In otolaryngology, key indicator procedure (KIP) minima are indicators of surgical exposure during training, yet it remains unknown how many times trainees must be evaluated on KIPs to ensure operative competence. Herein, we used Bayesian mixed effects models to compute predicted performance expectations for KIPs. METHODS: From November 2017 to September 2021, a smartphone application (SIMPL OR) was used by attendings at five otolaryngology training programs to rate resident operative performance after each case on a five-level scale. Bayesian mixed effects models were used to estimate the probability that postgraduate year (PGY) 3, 4, or 5 trainees would earn a "practice-ready" (PR) rating on a subsequent evaluation based on their previously earned PR ratings for each KIP. Probabilities of earning a subsequent PR rating were examined for interpretability, and cross-validation was used to assess predictive validity. RESULTS: A total of 842 assessments of KIPs were submitted by 72 attendings for 92 residents PGY 2-5. The predictive model had an average Area Under the Receiver Operating Curve of 0.77. The number of prior PR ratings that senior residents needed to attain a 95% probability of earning a PR rating on a subsequent evaluation was estimated for each KIP. For example, for mastoidectomies, PGY4 residents needed to earn 10 PR ratings whereas PGY5 residents needed 4 PR ratings on average to have a 95% probability of attaining a PR rating on a subsequent evaluation. CONCLUSION: Predictive modeling can inform assessment benchmarks for competency-based surgical education. LEVEL OF EVIDENCE: NA Laryngoscope, 133:3341-3345, 2023.

Residency Selection in Otolaryngology: Past, Present, & Future.

OBJECTIVES: To examine the otolaryngology residency selection process, including past experiences based on the medical literature and survey analysis of our present practices to generate recommendations for future selection system design. METHODS: A mixed-methods study, including a scoping review and a cross-sectional survey, was completed. Four databases were assessed for articles on otolaryngology residency selection published from January 1, 2016 through December 31, 2020. A 36-question survey was developed and distributed to 114 otolaryngology program directors. Descriptive and thematic analysis was performed. RESULTS: Ultimately, 67 of 168 articles underwent data abstraction and assessment. Three themes surfaced during the analysis: effectiveness, efficiency, and equity. Regarding the survey, there were 62 participants (54.4% response rate). The three most important goals for the selection process were: (1) to fit the program culture, (2) to make good colleagues, and (3) to contribute to the program's diversity. The three biggest 'pain points' were as follows: (1) Large volume of applications, (2) Lack of reliable information about personal characteristics, and (3) Lack of reliable information about a genuine interest in the program. CONCLUSIONS: Within this study, the depth and breadth of the literature on otolaryngology residency selection have been synthesized. Additionally, baseline data on selection practices within our specialty has been captured. With an informed understanding of our past and present, we can look to the future. Built upon the principles of person-environment fit theory, our proposed framework can guide research and policy discussions regarding the design of selection systems in otolaryngology, as we work to achieve more effective, efficient, and equitable outcomes.

Minimal Radiographic Mucosal Thickness or Opacification Criterion for Sinus-Specific Endoscopic Sinus Surgery for Chronic Rhinosinusitis.

OBJECTIVE: Primary chronic rhinosinusitis (CRS) is typically a diffuse process and the extent of endoscopic sinus surgery (ESS) performed for medically recalcitrant CRS is impacted by many factors. However, some third-party payors have implemented policies to authorize coverage for ESS in a sinus-by-sinus manner based on a minimal measurement of millimeters of mucosal thickening or sinus opacification in the corresponding sinus that is being surgically addressed. Our objective was to determine whether such policies are based on scientific evidence that in patients with medically recalcitrant CRS, a minimum measurement of mucosal thickening or sinus opacification is a predictor of CRS in that sinus or improved outcomes after ESS on a sinus-by-sinus basis. DATA SOURCES: Medline, Embase, Scopus, and Web of Science databases, from inception through May 2022. REVIEW METHODS: A systematic review was performed. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were followed. RESULTS: We identified 6070 abstracts which were screened and from which 112 studies ultimately underwent a full-text review. From these studies, we found that none investigated (or provided evidence of) whether any minimal degree of radiographic mucosal thickening or sinus opacification predicted CRS or better outcomes after ESS in a sinus-specific manner. CONCLUSION: We were unable to find evidence supporting a minimum millimeter measurement of mucosal thickening or sinus opacification as predictors of CRS or better post-ESS outcomes in a sinus-specific manner in patients with medically recalcitrant CRS. The extent of ESS for CRS should be determined through personalized medical decision-making that considers all patient-specific factors.

Molecular Evidence for Olfactory Neuroblastoma as a Tumor of Malignant Globose Basal Cells.

Olfactory neuroblastoma (ONB, esthesioneuroblastoma) is a sinonasal cancer with an underdeveloped diagnostic toolkit, and is the subject of many incidents of tumor misclassification throughout the literature. Despite its name, connections between the cancer and normal cells of the olfactory epithelium have not been systematically explored and markers of olfactory epithelial cell types are not deployed in clinical practice. Here, we utilize an integrated human-mouse single-cell atlas of the nasal mucosa, including the olfactory epithelium, to identify transcriptomic programs that link ONB to a specific population of stem/progenitor cells known as olfactory epithelial globose basal cells (GBCs). Expression of a GBC transcription factor NEUROD1 distinguishes both low- and high-grade ONB from sinonasal undifferentiated carcinoma, a potential histologic mimic with a distinctly unfavorable prognosis. Furthermore, we identify a reproducible subpopulation of highly proliferative ONB cells expressing the GBC stemness marker EZH2, suggesting that EZH2 inhibition may play a role in the targeted treatment of ONB. Finally, we study the cellular states comprising ONB parenchyma using single-cell transcriptomics and identify evidence of a conserved GBC transcriptional regulatory circuit that governs divergent neuronal-versus-sustentacular differentiation. These results link ONB to a specific cell type for the first time and identify conserved developmental pathways within ONB that inform diagnostic, prognostic, and mechanistic investigation.

Augmented Reality in Otology/Neurotology: A Scoping Review with Implications for Practice and Education.

OBJECTIVE: To determine how augmented reality (AR) has been applied to the field of otology/neurotology, examine trends and gaps in research, and provide an assessment of the future potential of this technology within surgical practice and education. DATA SOURCES: PubMed, EMBASE, and Cochrane Library were assessed from their inceptions through October 2022. A manual bibliography search was also conducted. REVIEW METHODS: A scoping review was conducted and reported according to PRISMA-ScR guidelines. Data from studies describing the application of AR to the field of otology/neurotology were evaluated, according to a priori inclusion/exclusion criteria. Exclusion criteria included non-English language articles, abstracts, letters/commentaries, conference papers, and review articles. RESULTS: Eighteen articles covering a diverse range of AR platforms were included. Publication dates spanned from 2007 to 2022 and the rate of publication increased over this time. Six of 18 studies were case series in human patients although the remaining were proof of concepts in cadaveric/artificial/animal models. The most common application of AR was for surgical navigation (14 of 18 studies). Computed tomography was the most common source of input data. Few studies noted potential applications to surgical training. CONCLUSION: Interest in the application of AR to otology/neurotology is growing based on the number of recent publications that use a broad range of hardware, software, and AR platforms. Large gaps in research such as the need for submillimeter registration error must be addressed prior to adoption in the operating room and for educational purposes.

Management paradigms for chronic rhinosinusitis in individuals with asthma: An evidence-based review with recommendations.

BACKGROUND: Despite the significant morbidity associated with chronic rhinosinusitis (CRS) in individuals with asthma (CRSwA), there is a paucity of codified, evidence-based management strategies for CRS in this population. METHODS: Using PubMed, Embase, and Cochrane Review Databases, a systematic review was performed covering management strategies for CRSwA. A total of 5903 articles were screened, and 70 were included for full-text analysis. After application of exclusion criteria, 53 articles comprised the qualitative synthesis. The level of evidence was graded and benefit-harm assessments, as well as value judgment and recommendations, were provided RESULTS: Strong evidence confirms the benefit of oral and topical medications on sinonasal-specific outcomes in individuals with CRSwA; there is low-grade evidence demonstrating that these agents improve lung function and/or asthma control. Moderate to strong evidence suggests that endoscopic sinus surgery (ESS) improves both sinonasal- and asthma-specific quality of life. Although there is insufficient to low evidence to indicate that ESS improves pulmonary function in this population, data indicate a positive impact of this intervention on asthma control. Biologic medications strongly improve both subjective and objective sinonasal- and asthma-specific outcomes. CONCLUSION: Evidence supports managing CRS in individuals with CRSwA in a stepwise fashion, starting with traditional nonbiologic oral and topical medication, and escalating to second-line treatments, such as ESS and biologics. Optimal treatment of individuals who have CRSwA often requires concurrent, directed management of asthma, as not all CRS interventions impact asthma status.

Telemedicine Services Provided to Medicare Beneficiaries by Otolaryngologists in 2020.

Telemedicine utilization among otolaryngologists was rare prior to the COVID-19 pandemic. We sought to understand rates of telemedicine utilization by otolaryngologists amid unprecedented changes in care delivery during the pandemic. Using Medicare Physician/Supplier Procedure Summary data, we performed a retrospective cross-sectional analysis of telemedicine services provided to Medicare beneficiaries by otolaryngologists in 2020. The total number of services and amount of reimbursement received by otolaryngologists for telemedical care increased by 52,989% and 73,147% in 2020 relative to 2019: 139,094 vs 262 services and $9.9 million vs $13,536, respectively. The mean telemedicine revenue per otolaryngologist offset only 8.8% ($9304.69) of losses from the reduction in mean in-person revenue between 2019 and 2020. Further research will be necessary to inform successful adoption of telemedicine within our field amid the ongoing COVID-19 pandemic.

A Needs Assessment for the Future of Otolaryngology Education.

The field of otolaryngology-head and neck surgery is rapidly changing, and surgical education must keep pace. In the face of recent advances in medical knowledge, surgical technique, and novel technology, educators may find it increasingly difficult to identify the evolving educational needs of otolaryngology residents. To better align training activities with modern practice patterns, we propose conducting a longitudinal needs assessment by designing a standardized specialty-specific survey for practicing otolaryngologists. This recurring survey could be implemented alongside accreditation or other continuing medical education activities. The outcomes would report what contemporary otolaryngologists see and do in everyday practice to guide educational reforms to better prepare trainees for future practice.

Otolaryngology residents' experiences of pregnancy and return to work: A multisite qualitative study.

Objectives: A paucity of literature exists about childbearing during otolaryngology residency. Pregnancy is a common part of many physician life cycles, but the timing of residency and the rigors of surgical training amplify the challenges. This study was designed to understand the experiences of childbearing otolaryngology residents and support them during this major life event. Unique challenges include long training, shortage of role models, combination surgical and clinical work, and higher rates of infertility. Study Design: Qualitative research. IRB exempt. Setting: United States. Methods: To capture modern perspectives, 16 current and former otolaryngology residents that experienced pregnancy and childbirth during residency in all four geographic regions of the United States in the past 10 years were recruited to participate in individual structured qualitative interviews. Results: Although there was significant training program and personal anxiety reported by childbearing otolaryngology residents, many surgeons experienced healthy pregnancies and postpartum recoveries with minimal disruption to clinical productivity and minimal disruption to their training programs. Multiple recurring themes were identified among the participants spanning the entire childbearing process: increased incidence of pregnancy complications and preterm labor, pregnancy stigma from leadership and coresidents, scheduling logistics regarding call and parental leave, and challenging transitions back to clinical work while navigating breastfeeding and childcare. Conclusion: There are actional recommendations that programs can address to make childbearing during residency accessible and acceptable. Understanding these challenges is an important step to encouraging childbearing residents to prosper in academic otolaryngology, increasing the diversity at the highest levels of the field. Level of Evidence: 4.
