AbstractObjectiveThe objective of this study is to determine if a history of traumatic brain injury (TBI) degrades postoperative the audiological performance of patients with cochlear implantation (CI).Study DesignRetrospective review.SettingDepartment of Defense‐wide database.MethodsInternational Classification of Diseases, Ninth Revision (ICD‐9) and ICD‐10 codes were used to identify patients that were diagnosed with TBI prior to CI between 2005 and 2023. They were matched 2:1 with controls without TBI based on age and sex. Preoperative and postoperative pure tone average (PTA) thresholds and AzBio scores were compared.ResultsNineteen TBI patients representing 20 implanted ears were identified and matched with 39 patients without TBI representing 40 implanted ears. Thirteen ears carried a diagnosis of mild TBI, and seven were diagnosed with moderate to severe TBI. The average follow‐up period was 44 months. The TBI group attained mean postoperative PTA and AzBio scores of 37 dB (SD 24) and 67% (SD 28). The non‐TBI group attained scores of 31 dB (SD 12) and 69% (SD 26). P‐values for the PTA and AzBio intergroup comparisons were .93 and .88, respectively. All TBI ears attained at least sound awareness after implantation, with 79% achieving open‐set speech perception compared to 82% of non‐TBI ears.ConclusionCI after TBI of any severity provides hearing rehabilitation comparable to patients without a prior diagnosis of TBI.

Objective To examine the quality of information provided by artificial intelligence platforms ChatGPT-4 and Claude 2 surrounding the management of vestibular schwannomas. Study design Cross-sectional. Setting Skull base surgeons were involved from different centers and countries. Intervention Thirty-six questions regarding vestibular schwannoma management were tested. Artificial intelligence responses were subsequently evaluated by 19 lateral skull base surgeons using the Quality Assessment of Medical Artificial Intelligence (QAMAI) questionnaire, assessing “Accuracy,” “Clarity,” “Relevance,” “Completeness,” “Sources,” and “Usefulness.” Main Outcome Measure The scores of the answers from both chatbots were collected and analyzed using the Student t test. Analysis of responses grouped by stakeholders was performed with McNemar test. Stuart-Maxwell test was used to compare reading level among chatbots. Intraclass correlation coefficient was calculated. Results ChatGPT-4 demonstrated significantly improved quality over Claude 2 in 14 of 36 (38.9%) questions, whereas higher-quality scores for Claude 2 were only observed in 2 (5.6%) answers. Chatbots exhibited variation across the dimensions of “Accuracy,” “Clarity,” “Completeness,” “Relevance,” and “Usefulness,” with ChatGPT-4 demonstrating a statistically significant superior performance. However, no statistically significant difference was found in the assessment of “Sources.” Additionally, ChatGPT-4 provided information at a significant lower reading grade level. Conclusions Artificial intelligence platforms failed to consistently provide accurate information surrounding the management of vestibular schwannoma, although ChatGPT-4 achieved significantly higher scores in most analyzed parameters. These findings demonstrate the potential for significant misinformation for patients seeking information through these platforms.

Objectives Evaluate the training background of surgeons performing high volumes of cochlear implants (CIs) and estimate the ratio of providers trained in otology/neurotology (O&N) to the number of traditional CI candidates and audiologists. Methods A retrospective review of US surgeon registration data from a single CI manufacturer was performed to determine CI volume based on surgeon training. The prevalence of traditional candidates for CIs was estimated from US census population data and compared with the number of O&N providers. The ratio of audiologists to O&N providers was estimated from the Bureau of Labor and Statistics and American Speech‐Language‐Hearing Association databases. Results From 2021 to 2023, a mean of 88% of providers performing ≥25 CIs per year and 90% performing ≥40 per year had training in O&N. All surgeons registering ≥100 implants per year were O&N providers. The mean percentage of O&N providers performing ≥25 CIs per year and ≥ 40 per year was higher than the percentage of General and Pediatric Otolaryngology providers performing the same volume: mean difference = 76%, p < 0.001 and mean difference = 79%, p < 0.001, respectively. The mean estimated prevalence of traditional CI candidates per O&N provider is 3,354 with an estimated mean of 32 audiologists (3.5 trained in CIs) per O&N provider. Conclusion 88% of high‐volume CI surgeons have fellowship training in O&N. To meet the current state of CI underutilization and anticipated growing population of CI candidates, we propose increasing the surgical capacity of O&N providers and the number of surgeons proficient in CIs.

ObjectiveUbiquitous throughout the literature and during patient counseling, vestibular schwannoma is often quoted to affect about 1 per 100,000 people. Yet, reports from distinct international populations suggest that the incidence is likely much higher. The objective of the current work was to systematically characterize the global incidence of sporadic vestibular schwannoma.Data SourcesScopus, Embase, and PubMed.Review MethodsPopulation‐based studies reporting incidence rates of sporadic vestibular schwannoma between January 2010 and August 2020 were searched with language restrictions requiring reports to be published in Chinese, English, German, Italian, or Spanish. The protocol was registered with PROSPERO (CRD42021228208) prior to commencement of data collection. PRISMA guidelines for transparent reporting of systematic reviews were followed.ResultsAmong 424 citations, 6 publications covering 4 distinct populations from Denmark, the Netherlands, Taiwan, and the United States met inclusion criteria. Most recent incidence rates of among all ages ranged between 3.0 and 5.2 per 100,000 person‐years. Highest incidence rates were reported among patients aged ≥70 years, peaking at 20.6 per 100,000 person‐years. One study from the United States reported the incidence of asymptomatic, incidentally diagnosed tumors at a rate of 1.3 per 100,000 person‐years from 2012 to 2016.ConclusionsRecent international incidence rates of sporadic vestibular schwannoma exceed the commonly quoted “1 per 100,000” figure by up to 5‐fold among all ages and by up to 20‐fold among age groups at highest risk. Based on modern incidence rates, the lifetime prevalence of developing sporadic vestibular schwannoma likely exceeds 1 per 500 persons.
