Cochlear Implantation and Vestibular Schwannoma Management

Abstract

Purpose of Review This review examines recent literature on cochlear implantation (CI) in patients with vestibular schwannomas (VS), both in sporadic and Neurofibromatosis Type 2 (NF2)-associated schwannomatosis. Indications, post-operative outcomes, and the impact of tumor management strategy on CI performance are reviewed. The key objective is to identify research gaps that warrant further investigation. Recent Findings Improvement in speech perception, sound localization, and quality-of-life metrics are observed after CI in VS patients. Key considerations in candidate selection include tumor size, contralateral hearing status, and intra-operative cochlear nerve function. CI outcomes in sporadic VS are influenced by tumor management modality, with less invasive approaches demonstrating potentially more favorable results. Summary The review underscores the potential of CI as a hearing rehabilitation option for VS patients no longer benefiting from amplification. Future research should explore neural integrity biomarkers, timing of implantation, and quality-of-life measures specific to the VS population.
