Basics
How long does a cochlear implant last?
The internal implant is designed to last a lifetime. The external sound processor is typically upgraded every 6–10 years as technology advances.
Modern internal implants have decades of clinical data and high long-term reliability. Manufacturers publish cumulative survival rates for each device family. Revision surgery for internal device failure is uncommon.
The external sound processor, in contrast, is a consumer-grade electronic device subject to wear. Most insurance/scheme/upgrade pathways allow processor replacement after a few years. Batteries, microphones and cables are user-replaceable consumables.
