Extracochlear Implantation: Technique and Results

Abstract

The authors present an overview of the technique and results in the rehabilitation of totally deaf adults by an extracochlear single-channel electrode. Eight patients were implanted with a follow-up of at least 6 months. Sound signal processing, the receiver, and the electrode are described. The access to the round window is through the facial recess. The internal coil is placed over the pectoral muscle. The rehabilitation program consists of training patients to recognize background sounds up to more discriminating exercises. The results are discussed.
