Abstract
Acquired severe to profound hearing loss is an increasingly challenging problem of our aging population. Cochlear implantation (CI) is the gold standard treatment for this advanced form of sensory deprivation. Despite the overall satisfactory results of CI, a substantial number of patients show unsatisfactory outcomes. This study aims to improve current predictive models of CI outcome by integrating preoperative MRI with behavioral data. We acquired a 3D T1 MRI to measure cortical thickness (CT) and volume using surface-based analysis and parcellation from the Brainnetome atlas. CI success at 6 months post-implant, as measured by audiovisual speech perception, was correlated with preoperative speech and audiovisual perception with hearing aids, and residual hearing, especially at the side of the non-implanted ear.
