Objective: To examine the association of extent of otosclerotic plaque using high-resolution photon-counting computed tomography (PCCT) with hearing and surgical outcomes. Study design: Historical cohort. Setting: Large academic center. Patients: Patients with otosclerosis who completed PCCT imaging at time of initial evaluation. Interventions: Observation, surgery. Main outcome measures: Audiometric data. Results: A total of 53 ears were eligible for study. The mean age at PCCT was 51 years (SD: 14). The mean extent of oval window otosclerotic plaque measured in radial degrees was 112 (SD: 65) and the mean otosclerotic depth was 1.6mm (SD: 0.6). The mean air-bone gap pure-tone average was 18 dB (SD: 12) and the mean Carhart degree was 9 dB (SD: 10). The radial degrees of oval window extent were not significantly associated with air-bone gap (correlation coefficient: 0.14; P =0.3) or Carhart degree (correlation coefficient: 0.04; P =0.8). Likewise, otosclerotic plaque depth was not significantly associated with air-bone gap (correlation coefficient: −0.19; P =0.2) or Carhart degree (correlation coefficient: −0.08; P =0.6). After PCCT, 22 ears underwent surgery. In this subset, oval window extent and plaque depth were not significantly associated with the postoperative changes in air-bone gap or high-frequency thresholds. Conclusions: Despite enhanced visualization of subtle abnormalities with PCCT imaging, the extent of oval window otosclerotic plaque, measured in angular degrees and depth, was not associated with hearing loss at time of initial evaluation or postoperative audiologic changes in patients with otosclerosis.

Objective: To evaluate the impact of cochlear implantation (CI) and simultaneous endolymphatic sac decompression (ELSD) on vestibular and audiometric outcomes in patients with advanced Ménière disease (MD). Study design: Historical cohort. Setting: Tertiary academic medical center. Patients: Patients with medically refractory MD who underwent CI with or without simultaneous ELSD from 2000 through 2024. Interventions: CI with or without ELSD. Main outcome measures: Post-CI patient-reported changes in vertigo severity and frequency, Consonant-Nucleus-Consonant word (CNCw) scores, and AzBio sentences in quiet scores. Results: Ninety-nine patients with preoperative vertigo secondary to MD were eligible for study, including 17 (17%) who underwent simultaneous ELSD. In total, 15 (88%) and 2 (12%) of the 17 patients with simultaneous ELSD reported improvement and stability in vertigo severity, respectively; in comparison, 26 (32%), 40 (49%), and 16 (20%) of the 82 patients with CI alone reported improvement, stability, and worsening in vertigo severity, respectively ( P <0.001). Likewise, 15 (88%) and 2 (12%) of the patients with simultaneous ELSD reported improvement and stability in vertigo frequency, respectively, whereas 21 (26%), 43 (52%), and 18 (22%) of patients with CI alone reported improvement, stability, and worsening in vertigo frequency, respectively ( P <0.001). Post-CI speech recognition scores were not significantly different between the simultaneous ELSD and CI alone groups [median (IQR) CNCw 70 (38 to 82) vs. 72 (58 to 82) and median (IQR) AzBio quiet 87 (67 to 96) vs. 87 (73 to 94), respectively]. Conclusions: In patients with MD, CI with simultaneous ELSD provides improvement in vertigo symptoms and similar audiometric outcomes when compared with CI alone. In appropriately selected patients with both refractory vestibular symptoms and sensorineural hearing loss meeting criteria for implantation, CI with simultaneous ELSD offers improvement in severity and frequency of vertigo as well as successful auditory rehabilitation.

Hearing loss is a highly prevalent disease state affecting almost 1 in 5 individuals globally. Growing research shows that untreated or undertreated hearing loss carries significant long-term sequelae, including increased risk of social isolation, depression, and cognitive decline, among other ramifications. Limited awareness and common misperceptions among the general US adult population and primary care providers contribute to low rates of referral to hearing specialty clinics and underutilization of hearing aids, cochlear implants, and other rehabilitative devices. Comprised of diverse membership, the Hearing Health Collaborative (HHC) was formed in May 2021 to identify and overcome challenges impacting good health care practices and public policy on hearing care in connection with healthy aging. This editorial documents a recent outcome of the HHC derived from a structured A3 process. Specifically, initiative 2, a proposal to develop a simple, clinically anchored staging system primarily for use by frontline providers and patients, is presented. Unlike other common disorders that harbor long-term health sequelae, a corresponding pragmatic clinical staging system—leveraging precedent disease staging convention, based on clinically meaningful outcomes and prognosis for acquired hearing loss—does not exist. The development of this staging system will potentially allow for improved communication across providers and patients, facilitate referral pathways, and ultimately enable patient access to timely and appropriate care.

Objective: To evaluate the ethical implications, clinical benefits, and challenges associated with centralizing the surgical care of vestibular schwannoma (VS) care. Databases reviewed: PubMed, Embase, CINAHL, Web of Science, Cochrane, Scopus. Methods: A scoping review was conducted per the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines. A comprehensive search of 6 electronic databases yielded 1,231 articles using keywords related to vestibular schwannoma, centralization of care, centers of excellence, and ethical considerations. After removing duplicates (n=344) and screening titles and abstracts (n=887), 17 full-text articles were reviewed. Two additional articles were identified through manual screening. A total of 15 studies were included in the final analysis. Results: Hospitals were categorized by surgical case volume (high, medium, low) to compare patient demographics and clinical outcomes. Patients seen at low-volume hospitals (LVHs) were generally older and more racially diverse, and more likely to have public insurance (Medicare or Medicaid), whereas high-volume hospitals (HVHs) served a younger, predominantly White, and privately insured population. Of the 14 studies evaluating outcomes, 12 demonstrated a positive association between higher surgical volume and improved outcomes, including reduced complications, lower mortality, shorter length of stay, and decreased hospitalization costs. High-volume hospitals also had significantly higher rates of routine discharge. Conclusion: Centralization of vestibular schwannoma care to high-volume centers is associated with improved clinical outcomes and reduced health care costs. However, these benefits must be carefully weighed against potential ethical concerns, including disparities in access related to socioeconomic status, insurance coverage, and geographic location.

Objective: The Complete Cochlear Implant Care (CCIC) model is a highly coordinated care delivery model reducing and condensing in-person visits for cochlear implant (CI) patients, leveraging telehealth and remote programming. Clinical, quality-of-life, implementation, patient experience, and financial outcomes of the clinical trial are reported. Study design: Prospective, nonrandomized, 2-arm clinical trial Setting: Tertiary referral CI center Patients: Adult CI candidates Interventions: Cochlear implantation Main outcome measures: Speech perception, quality of life, implementation, patient experience, and financial outcomes for both CCIC and traditional care delivery models. Results: Patients participating in the traditional and CCIC delivery models demonstrated 12-month postoperative speech perception scores comparable to nationally reported outcomes (CNC 61% and 72% and AzBio in quiet 75% and 87% for traditional and CCIC cohorts, respectively). Quality-of-life evaluation using the CIQOL-10 demonstrated similar 12-month postoperative scores between groups (52 and 54 for traditional and CCIC cohorts, respectively). The CI Patient Experience Survey demonstrated high satisfaction outcomes in ease of communication, preparedness for surgery, and overall care in both cohorts. Implementation analysis of the CCIC model revealed perceived benefits from staff and clinicians; however, support for expansion of the program was contingent upon the availability of app-based or web-based remote programming technology. Finally, financial analysis revealed decreased out-of-pocket costs for CCIC patients. Conclusion: The CCIC model has the potential to dramatically streamline hearing health care delivery and reduce out-of-pocket costs for CI recipients. Clinical outcomes between cohorts were comparable in this feasibility study; however, a sufficiently powered trial is required to definitively comment on clinical outcomes with the new care delivery model.

Objective: To characterize patient outcomes after primary stereotactic radiosurgery (SRS) for the management of sporadic facial nerve schwannoma. Study design: Retrospective cohort study. Setting: Six tertiary referral centers across the United States and United Kingdom. Patients: Adults undergoing SRS from 2000 through 2023 for sporadic facial nerve schwannoma along any segment of the facial nerve were included. Patients with NF2-related schwannomatosis were excluded. Intervention: Stereotactic radiosurgery. Main outcome measure: Long-term tumor control. Results: Among 60 patients meeting inclusion, the median age at SRS was 52 years (IQR: 41 to 64) with a median tumor size of 19.5 mm (IQR: 14.7 to 22.8). Tumors commonly involved the internal auditory canal (73%), cisternal (49%), geniculate/labyrinthine (47%), and tympanic segments (22%). Two patients experienced SRS failure and underwent salvage treatment; salvage-free survival rates (95% CI; number still at risk) at 1, 3, 5, and 10 years after SRS were 100% (100 to 100; 55), 100% (100 to 100; 36), 100% (100 to 100; 18), and 87% (72 to 100; 9), respectively. Among 31 (52%) patients with House-Brackmann (HB) grade I facial function at presentation, only 6 demonstrated worse facial function at a median of 3.2 years (IQR: 1.7 to 6.6) after SRS. Of 18 patients with serviceable hearing (AAO-HNS class A/B) at SRS, 13 maintained serviceable hearing at a median of 1.0 years (IQR: 0.5 to 4.9) of post-SRS audiometric follow-up. Conclusions: Durable tumor control after primary SRS for sporadic facial nerve schwannoma is achieved in most patients. Among those with HB grade I facial function at presentation, treatment with SRS harbors limited additional risk of facial paresis beyond observation alone.

Objective: Vestibular schwannomas (VSs) treated with stereotactic radiosurgery (SRS) often show transient loss of central tumor enhancement. We hypothesized that this loss of enhancement may correlate with better tumor control on follow-up imaging. Methods: We evaluated 198 consecutive patients from a single center who met eligibility criteria. Tumor volumes on the pre-SRS and post-SRS scans were quantified along with regions of loss of enhancement on the first post-SRS study. The latter was correlated with tumor volumes at follow-up, radiation isocenter density, and loss of serviceable hearing. Results: For the entire cohort, the median loss of enhancement on the first post-SRS scan was 14% (IQR: 6 to 25) and median rate of change in tumor volume was −4.5% per year (IQR: −10.5 to 1.5). Percent loss of central enhancement showed significant negative correlation with tumor growth not only for the entire cohort (correlation coefficient: −0.18, P =0.01), but also for the subset of patients who had available imaging until at least 2 years (n=185) and 4 years (n=179) post-SRS. Loss of enhancement also strongly correlated positively with tumor volumes and number of radiation isocenters and negatively with isocenter density. Finally, patients with greater percent loss of enhancement had an increased likelihood of progression to non-serviceable hearing, although this association was not statistically significant. Conclusions: These findings suggest that loss of central tumor enhancement in VSs post-SRS may be associated with improved tumor control.

Importance Adverse events in otolaryngology–head and neck surgery (OHNS) are inconsistently reported. The Clavien-Dindo Classification has been modified and validated in several surgical subspecialties but has yet to be validated in OHNS. Objective To create and validate a modified Clavien-Dindo Classification for OHNS that reflects the severity and duration of harm for complications experienced by patients undergoing OHNS. Design, Setting, and Participants This is a multicenter survey study of subject matter experts (SMEs) from OHNS subspecialties from academic institutions within the US. A literature review identified publications reporting surgical complications in OHNS in the English language between January 2019 and April 2020. Complications were summarized and used to inform a modified Clavien-Dindo Classification. Feedback from internal SMEs was incorporated. Thirty-five clinical vignettes were created, and an electronic survey was sent to SMEs at outside institutions. Each SME was randomly assigned to 1 of 4 groups to evaluate 8 to 9 vignettes. The survey was conducted in September 2023, and data were analyzed from February to May 2024. Exposure Participation in the electronic survey. Main Outcomes and Measures Vignette scores were assessed and the Comprehensive Complication Index (CCI) calculator was used to assess cumulative morbidity. The scale is based on the grading by the Clavien-Dindo Classification and reflects overall morbidity on a scale from 0 (no complication) to 100 (death). Variability of the CCIs between reviewers, the primary outcome, was summarized with the SD. The percentage of reviewers with a high (≥26.2) or low (&amp;lt;26.2) CCI within a vignette was reported. Reliability was summarized using Krippendorff α. Results Of 106 SMEs, 43 (response rate, 40.6%) completed at least 1 vignette. Eighteen of 35 vignettes (51.4%; 95% CI, 34.9%-68.0%) had unanimous high CCI, and 8 of 35 vignettes (22.9%; 95% CI, 8.9%-36.8%) had unanimous low CCI (overall categorical agreement, 74.3%; 95% CI, 59.8%-88.8%). On average, the Krippendorff α was 0.74, indicating moderate reliability. A total of 21 850 OHNS complications were reviewed and categorized as surgical or medical with 12 including subcategorization for specificity. Each category was then assigned a modified OHNS Clavien Dindo classification grade. Conclusions and Relevance In this survey study of OHNS experts, a modified OHNS Clavien-Dindo Classification was developed and validated using case vignettes. The modified Clavien-Dindo Classification provided a granular subcategorization for each complication category and grade, duration of harm, and an overall summary complication score (CCI). Results suggest the modified OHNS Clavien-Dindo Classification reliably differentiated between high-grade and low-grade OHNS complications and could be utilized for assessing surgical outcomes.

Objective: To systematically review the existent literature on radiosurgery for treatment of sporadic facial nerve schwannomas (FNS). Databases reviewed: PubMed, SCOPUS, EMBASE, and Web of Science databases. Methods: Systematic review was performed per PRISMA criteria of studies published from 1990 through 2024 on patients diagnosed with sporadic FNS who were treated with radiosurgery. Outcomes included change in facial nerve function, change in hearing class, and radiosurgical treatment failure defined by need for reintervention. Study quality was assessed using the LEGENDS rubric for mixed modality studies. Results: In total, 35 studies encompassing 364 patients were included for data abstraction. Gamma Knife was the most common modality reported. Longitudinal patient-level data on facial nerve function were available for 101 patients, with 8% of patients experiencing worsening facial nerve function and 92% of patients having either stable nerve function or improvement in facial nerve function following treatment over a median follow-up of 36 months. Longitudinal patient-level hearing data were available for 53 patients, including 35 patients with serviceable hearing (AAO-HNS class A or B) at baseline; only 2 patients developed nonserviceable hearing (AAO-HNS class C or D) following treatment over a median follow-up of 36 months. Clinical tumor control data were available for 295 patients, of whom 11 required salvage treatment over a mean follow-up of 49 months. Conclusions: This systematic review demonstrates a relatively low risk of worsening facial nerve function and a high rate of clinical tumor control following radiosurgery for sporadic FNS.

Background Sinonasal pathology, such as chronic inflammatory disease or neoplasm, can cause secondary nasolacrimal duct obstruction (sNLDO). There is a paucity of data on dacryocystorhinostomy (DCR) techniques and outcomes for NLDO secondary to known sinonasal pathologies. Objective To describe case characteristics, management, and surgical outcomes of sNLDO at a tertiary academic center. Methods Charts of DCR cases with at least 3 months follow-up done at a single institution over a 5-year period (2018-2022) were reviewed. Patient and surgical characteristics were recorded and compared between secondary and primary NLDO groups. The primary outcome was early functional success of DCR, assessed by improvement or resolution of epiphora at 3 months. Results A total of 236 cases were included. Of those, 79 (33.5%) were classified as secondary NLDO associated with sinonasal pathology. Reasons for sNLDO were sinonasal cancer (46.8%), chronic inflammatory disease (24.1%), trauma (16.5%), or prior head and neck radiation (31.6%). When comparing primary acquired NLDO to sNLDO cases, DCR for sNLDO was more likely to be performed endoscopically (68.4% vs 31.8%, P < .01), by a multidisciplinary team of rhinologist and oculoplastic surgeon (70.9% vs 8.3%, P < .01), and required bilateral surgery (36.7% vs 5.7%, P < .01). The overall functional success rate was 79.7% for sNLDO compared to 87.9% for primary acquired NLDO ( P < .01). Revision surgery for sNLDO, history of sinonasal malignancy, and radiation were associated with lower functional success rates (66.7%, 70.3%, and 68.0%, respectively). Canalicular pathology was more common in sNLDO cases (29.0% vs 8.3%, P < .01). Conclusions Secondary NLDO was more commonly managed with an endoscopic approach by a multidisciplinary team. Revisions for sNLDO, as well as cases with a history of sinonasal malignancy and radiation, had a markedly lower success rate, and sNLDO was frequently associated with canalicular obstruction. These findings may facilitate surgical planning and patient counseling.
