Device failure and revision surgery
Modern cochlear implants have very high long-term reliability. If an internal device fails, revision (re-implantation) surgery is safe and effective.
Manufacturers publish cumulative survival data — typically 95%+ at 10 years for current devices. When a failure occurs, the implant is removed and a new one inserted, usually in the same surgery. Most users return to similar hearing performance after revision.
Non-device causes (electrode misplacement, anatomic factors) can also occasionally need revision and are addressed individually.
