CLINICAL TRIAL OF A MULTI‐CHANNEL COCHLEAR PROSTHESIS: RESULTS ON 10 POSTLINGUALLY DEAF PATIENTS

Abstract

The clinical trial of a multi‐channel cochlear prosthesis has been carried out on 10 profoundly‐totally deaf adult patients. Speech perception tests have shown that all the patients received significant benefit from the device.
