Background: Evaluation of otolaryngology resident technical performance has historically relied on subjective perioperative feedback. Despite various assessment tools attempting to provide consistent surgical skill evaluations, current methods remain inherently subjective. Aim: This proof-of-concept pilot study aimed to assess if a 3-dimensional surgical navigation system could capture objective surgical data during endoscopic sinus surgery (ESS). A secondary aim was to analyze if there were any differences between novice and practiced trainees. Methods: Otolaryngology residents performed supervised ESS on patients while their instrument (microdebrider, suction) motion was recorded using a TruDi ® Navigation System. Prior to the surgery, surgical landmarks were defined with sensory beacons in the navigation system using the patient’s preoperative computed tomography (CT) scan. Metrics included time to reach beacons, number of alerts at each beacon, and instrument speed. Results: Fifteen otolaryngology residents performed 87 ESS. The navigation system successfully obtained “time to reach sinus X” data for 64% of sinuses/ case, velocity data in 93% of cases, and number of beacon “alerts” per minute in 93% of cases. We found a significant difference between PGY 3 residents and PGY 4/PGY5 residents in the number of sphenoid sinus alerts per minute ( P = .01) and the percentage of cases in which the resident accessed the maxillary sinus via the natural os ( P < .001). Impact: This study demonstrates the feasibility of collecting objective, navigation-based intraoperative metrics during live surgery and is a first step toward building a comprehensive objective assessment tool in ESS. We hope this report encourages further research into this technology’s application in objective resident skill assessment and correlation with concurrent faculty assessments.

BACKGROUND AND OBJECTIVES: Surgery in NF2-related schwannomatosis (NF2-SWN) vestibular schwannoma (VS) carries a higher risk of facial nerve damage, hearing loss, and partial resection, than in sporadic cases. Radiosurgery is also associated with higher failure compared with sporadic schwannomas. Nowadays, bevacizumab (BEV) is frequently considered in the NF2-SWN population. However, some patients experience progression despite treatment. Among other surgical risks, in BEV-treated patients, hemorrhage and impaired healing are specific considerations. These concerns have led manufacturers to recommend stopping BEV 6 to 8 weeks preoperatively. The aim of our multicentric study was to assess the perioperative bleeding risk and postoperative outcomes in NF2-SWN patients undergoing VS surgery after preoperative BEV treatment. METHODS: Our retrospective analysis included medical and surgical records along with imaging reviews from 4 high-volume tertiary academic referral centers for NF2-SWN and VS. RESULTS: A total of 21 patients met the inclusion criteria. VS had a mean volume of 13.2 ±7.6 cm 3 corresponding to 1 KOOS III and 20 KOOS IV. BEV was stopped at a mean of 5.8 ± 4.0 months before surgery with a total mean treatment duration of 33.7 ± 20.7 months and a monthly dose of 10.2 ± 4.1 mg/kg. Intraoperatively, the tumor was assessed to be bloody by the operating surgeons in 7 patients. Late BEV discontinuation and high cumulative dose independently predicted perioperative bleeding and longer surgery duration. No other complication such as wound dehiscence was reported. CONCLUSION: Our findings suggest that a higher cumulative BEV dose (∼600 mg/kg) and a longer interval between BEV discontinuation and surgery (∼8 months) are associated with a modest but statistically significant increase in intraoperative bleeding risk. Based on these observations, a BEV-free window between 6 weeks and 6 months (depending on the clinical scenario) before tumor resection seems optimal, particularly for patients with high cumulative exposure.

Objective: To develop, implement, and evaluate a novel process used for residency application review that deemphasizes metrics known to create bias with the goal of interviewing and matching a more diverse resident cohort. Methods: Between 2020 and 2023, a novel standardized rubric and application review process were developed and implemented at the authors’ academic training program. The rubric deemphasized USMLE scores, honor society membership, and number of publications while utilizing an AI-driven pre-sort of applications, facilitating holistic review. This weighted applicant attributes identified in personal statements, life experiences, achievements in community, leadership roles, otolaryngology-specific impressions highlighted in letters of recommendation, and otolaryngology-specific research and publications similarly to academic metrics (clerkship grades and standardized test scores). Demographics of applicants interviewed and matched into our program were compared pre- and post-implementation using descriptive statistics. Results: Using a standardized rubric to review residency applications that deemphasizes traditional metrics, the authors’ otolaryngology residency program has interviewed, ranked, and matched more diverse candidates. As a result, from 2019 to 2022, the overall resident cohort has diversified from 4% historically marginalized residents to 24%, from 28% female residents to 44%, and from 33% of residents outside our geographic region to 66%. Conclusion: There is significant underrepresentation among otolaryngology residents. Selection based upon USMLE Step 1 scores, honor society membership, and number of publications have been shown to restrict diversity. Purposeful holistic review increases diversity in interviewed and matched resident cohort.

Importance In the literature, there is a lack of data reporting tumor control rates after radiotherapy in actively growing vestibular schwannomas (VS). Data for this rarely studied population are needed. Objective To estimate tumor control rates in radiologically growing VS treated with first-line radiotherapy. Design, Setting, and Participants This international, multicenter cohort study used prospectively collected data from patients with growing unilateral VS treated first-line with radiotherapy between January 2000 and December 2023 from 8 tertiary referral skull base units. The data were analyzed in June 2025. Exposures Radiotherapy as an initial treatment for VS. Main Outcomes and Measures The primary outcome was treatment failure, ie VS growth postradiotherapy, which was predefined as an increase in maximum intracranial tumor diameter (ICTD) of 3 mm or greater within the first 2 years after radiotherapy or 2 mm or greater thereafter. Secondary outcomes were treatment failure based on different definitions of VS growth: (1) an increase in ICTD of 2 mm or greater, (2) an increase in ICTD of 3 mm or greater, and (3) conversion to surgery. Results A total of 1883 patients (975 female individuals [51.8%]; median age at diagnosis, 63 years [IQR, 53-71 years]) were included in the study. Using the primary definition of treatment failure (an increase in ICTD of ≥3 mm within the first 2 years postradiotherapy or ≥2 mm thereafter), the Kaplan-Meier estimate yielded a 10-year tumor control rate of 76.1% (95% CI, 72.7%-79.2%). For secondary outcome definitions, 10-year tumor control rates were 60.1% (95% CI, 57.5%-64.3%) for an ICTD increase of 2 mm or greater, 78.3% (95% CI, 75.0%-81.2%) for an increase of 3 mm or greater, and 92.6% (95% CI, 90.4%-94.3%) for conversion to surgery. Neither pretreatment tumor size nor tumor location (intracanalicular vs extracanalicular) were significantly associated with treatment failure. Conclusions and Relevance The results of this cohort study provide tumor control outcomes for radiologically growing VS treated with radiotherapy using several clinically relevant definitions of growth. By focusing exclusively on this rarely isolated subgroup, the findings offer targeted data to potentially inform treatment expectations and future research.

ABSTRACT Background Prompt detection and intervention are crucial for improving outcomes in acute invasive fungal rhinosinusitis (AIFS). Diagnostic prediction models assist in risk‐stratification, but their accuracy requires testing through external validation. This study aims to validate a previously published diagnostic prediction model for AIFS in an independent cohort. Methods A retrospective chart review was conducted at a tertiary care center (2008–2023) to identify patients with an otolaryngology consult for suspected AIFS. Of 65 patients identified, 11 (16.9%) were diagnosed with AIFS based on histopathology. Risk was calculated using Yin et al.’s predictive model. Predictive performance was assessed by calibration and discrimination. Results Patients had significantly higher rates of diabetes (46.2% vs. 26.1%, p = 0.002), long‐term steroid use (60% vs. 28.2%, p < 0.0001), and solid organ transplantation (38.5% vs. 8.5%, p < 0.001), compared with the development cohort, with conversely lower rates of hematologic malignancy (29.2% vs. 58.7, p < 0.001) and neutropenia (19.4% vs. 41%, p = 0.001). Despite these differences, both the three‐variable (C‐index: 0.844; 95% CI, 0.736–0.952) and four‐variable models (C‐index: 0.963; 95% CI, 0.919–1) showed adequate discrimination. Both models exhibited slight overprediction of risk, with a calibration‐in‐the‐large predicted risk of 24.1% (95% CI, 13.68–34.46) for the three‐variable model and 24.2% (95% CI, 13.76–34.57) for the four‐variable model. Calibration plots confirmed overprediction. Conclusion The AIFS diagnostic model demonstrates acceptable discrimination and calibration on external validation, with generalizability to patients with different comorbidities. Larger studies are recommended to further test the model's predictive performance and clinical applicability.

Objective: To determine the impact of modifiable surgical factors on ossiculoplasty outcomes after controlling for ear environment risk. Study Design: Multi-institutional retrospective review. Setting: Six tertiary care centers from 2011 to 2019. Patients Adults and children. Interventions: Ossiculoplasty, including synthetic ossicular replacement prosthesis, autograft interposition, bone cement repair, and mobilization. Main Outcome Measure: Correlation between modifiable surgical factors and pure-tone average air-bone gap (ABG) at most recent audiogram after controlling for preoperative risk using the statistically validated Ear Environment Risk (EER) score. Results: A total of 1,679 cases were included with a median follow-up time of 20 months (IQR, 5–51). After controlling for EER score, malleus engagement of prosthesis yielded favorable ABG versus direct contact to tympanic membrane without malleus engagement (beta = −2.4 dB [−3.8, −1.1], p < 0.001). For total ossicular replacement prostheses (TORP), use of a footplate prosthesis yielded favorable ABG as compared with no footplate prosthesis (−3.6 dB [−6.1, −1.1], p = 0.005). For synthetic prostheses, polyethylene prostheses had a less favorable ABG compared with full titanium or titanium with hydroxyapatite prostheses ( p < 0.05). In cases where the malleus was not engaged in reconstruction, amputation of the malleus head yielded worse ABG (+3.9 dB [1.2, 6.7], p = 0.005). There was no significant difference ( p > 0.05) in ABG for single-stage versus multistaged approach, use of a cartilage cap over the prosthesis versus no cartilage, use of bone cement to secure a PORP to the stapes versus no cement, mastoid cavity obliteration versus no obliteration, and incudostapedial joint reconstruction with joint prosthesis/bone cement versus synthetic PORP. Conclusions: With statistical correction for ear environment risk, several modifiable surgical factors are noted to impact ossiculoplasty hearing outcomes. Level of Evidence: 4.

Aberrant internal carotid artery (ICA) is a vascular anomaly in which a segment of the ICA courses through the middle ear. The association of aberrant ICAs and pseudoaneurysm formation is not well known and can be an important finding to recognize on imaging. In this series, we present three cases of aberrant ICAs having asymmetric contour deformities consistent with pseudoaneurysms diagnosed utilizing CT of the temporal bone.

Objectives To compare electrical stimulation and speech perception in vestibular schwannoma (VS) patients across treatment modalities and standard cochlear implant (CI) patients. Study Design Retrospective review. Setting Tertiary academic center. Patients Sixty-seven CI ears consisting of 23 standard CI controls and 44 VS patients with ipsilateral CI. VS patients were separated by treatment modality: 24 microsurgical resection, 15 radiation therapy, and 5 observation. Eleven VS patients with CI did not receive auditory sensation from electrical stimulation. Interventions VS microsurgical resection, radiation therapy, and observation. Main Outcome Measures Threshold (T-levels), comfort (C-levels), consonant-nucleus-consonant (CNC) word score, and AzBio sentence recognition scores. Results Patients who underwent microsurgical resection required significantly higher (p < 0.001) T-levels and C-levels compared with the standard CI group. Stimulation levels in the VS radiation therapy and observation groups were higher but not significantly different compared with standard CI controls. Overall rate of CI nonstimulation across all VS patients was 25%: 38% for microsurgery and 13% for radiation. Average CNC score for microsurgery group was 18% compared with 44% for radiation, 55% for observation, and 68.5% for standard CI controls. CNC word and AzBio scores were significantly lower (p < 0.001) for the microsurgery group compared with standard CI group. Conclusions Resection may negatively affect auditory nerve function, leading to higher stimulation levels, increased risk of nonstimulation, and poorer postoperative CI speech outcomes compared with observation or radiosurgery. When medically appropriate, nonsurgical VS management may be used to allow for optimization of CI programming and postoperative hearing outcomes.

BACKGROUND: Surgical intervention remains an important option in the management of vestibular schwannoma (VSs). Development of a systematic approach to choose the most appropriate route for this intervention, based on existing published evidence, is an important goal. OBJECTIVE: To review the literature published since the 2018 Congress of Neurological Surgeons Guideline on surgical intervention for patients with sporadic VSs and use this information to update that set of recommendations. METHODS: The literature in the PubMed and MEDLINE databases from January 2015 through May 20, 2022, was searched for manuscripts pertaining to surgical intervention for VSs. Those manuscripts meeting inclusion criteria were then analyzed for creation of recommendations in response to a set of updated questions. RESULTS: The resultant findings included a considerable amount of data that did not alter the recommendations form the 2018 publication on this topic. Thus, recommendations stating hearing preservation surgery through the middle fossa or retrosigmoid approach may be considered in individuals with good preoperative hearing as an alternative to simple observation remain. In addition, if microsurgical resection is necessary after stereotactic radiosurgery, it is recommended that patients be counseled that there is an increased likelihood of a subtotal resection and decreased facial nerve function. In some questions, insufficient data were present to create an answer and that is stated. CONCLUSION: This guideline demonstrates surgical intervention for VSs and represents a range of options, and the choice of the intervention depends on the specific aspects of the lesion and the individual that harbors them. Objective refinement of those choices will require thoughtful research design by investigations that wish to address those items for which we still have insufficient information.
