Background and Objectives This study aimed to comprehensively assess the factors influencinghearing ability in patients with vestibular schwannoma, focusing on tumor size, location,primary complaint, and contralateral hearing threshold. Subjects and Method This was a retrospective analysis of 50 patients diagnosed with vestibularschwannoma by magnetic resonance imaging (MRI) at Nowon Eulji Medical Center. Tumor size and location were evaluated using a 3-T MRI system, and pure-tone threshold andspeech discrimination were retrieved. To investigate the relationship between tumor size andhearing, we conducted a multiple regression analysis with several variables, including tumorsize, tumor location, patient age, and gender. Results When patients were categorized into groups according to their primary complaint atinitial presentation, no significant differences were observed in pure tone thresholds but differentspeech discrimination were detected among the groups. When patients were classifiedaccording to the tumor location, the extrameatal group exhibited lower pure-tone thresholdsand higher speech discrimination scores than the intrameatal group. Multiple regression analysisindicated that differences in pure tone thresholds and speech discrimination scores betweenaffected and unaffected sides were more pronounced in cases with smaller tumor sizesand extrameatal tumor locations, emphasizing the greater impact of location over size. Conclusion Using both tumor size and location, it is possible to predict the differences inpure-tone thresholds and speech discrimination between the affected and unaffected sides. Extrameatal invasion of the tumor appears to be the most important factor among them.
