Personalising cochlear implant care using cortical auditory-evoked potential responses: insights into improving mapping and rehabilitation outcomes

The cochlear implant (CI) is an effective auditory prosthesis; however, outcome variation post implantation presents a significant ongoing challenge, as the cause of poor performance remains poorly understood. Here, we explore cortical auditory-evoked potential (CAEP) measures as a tool to identify factors underlying performance variability and inform strategies to address it. The use of CAEPs provides objective insights that support personalising CI care through improved mapping and identification of variability related to individual device usage patterns. Personalised aural rehabilitation enhanced behavioural and self-reported outcomes in long-term adult CI recipients, offering a targeted approach to minimise variation and improve performance across users.
