Screening for discordant outcomes in cochlear implant users: Classification based on ECAP amplitudes

Cochlear implant (CI) recipients show considerable variability in postoperative speech recognition outcomes. While electrically evoked compound action potential (ECAP) recordings are routinely available in modern CI systems, their usefulness in routine clinical practice as a potential outcome measure has not been systematically established....

ECAP-based classification shows promise for identifying cochlear implant users with unexpectedly poor speech recognition outcomes; however, the method requires prospective validation before being integrated into routine post-operative monitoring protocols.

A reliable objective screening tool for discordant cochlear implant outcomes could trigger earlier intervention for underperforming patients and reduce reliance on lengthy behavioural assessments in clinical follow-up.
