CLINICAL-RESULTS FOR POSTLINGUALLY DEAF PATIENTS IMPLANTED WITH MULTICHANNEL COCHLEAR PROSTHESES

Abstract

Clinical results for 24 patients using the Nucleus 22-channel cochlear prosthesis have shown the device to be successful in presenting amplitude, fundamental frequency, and second formant information to patients with acquired hearing loss. For all patients, this has meant a significant improvement in their communication ability when using lipreading and some ability to understand unknown speech without lipreading or contextual cues.
