Atrophy of cerebellum Crus I indicates poor outcome of cochlear implantation in the elderly.

ABSTRACT: Cochlear implantation (CI) is a highly effective treatment for profound hearing loss in elderly individuals, including those with ARHL. However, factors influencing the success of CI in the elderly population are not fully understood. Hence, we sought to investigate the association of regional cerebellar gray matter volume with effectiveness of CI in the elderly. This retrospective cross-sectional study included CI implantees and healthy controls aged ≥ 70 years. We used voxel-based morphometry to investigate the cerebellar gray matter associated with speech perception outcome in the CI group. Among the study participants, cerebellar gray matter volume loss, particularly in the Crus I region, was associated with poorer CI outcomes. Notably, this association was stronger than that observed
