What is a cochlear implant?
Simply put, a cochlear implant is a hearing prosthesis. It bypasses the non-functioning part of the inner ear, the cochlea, and stimulates the hearing nerve. This is the main difference to a conventional hearing aid. The hearing nerve sends acoustic information to the brain which recognizes them as sound. Surgery is considered low risk and routine. A large UK study shows that the risk of major complications is small – around 1.6%.
