Cochlear implant device failure in the postoperative period: An institutional analysis

The Cochlear Implant

The studies on cochlear implants have been conducted in the United States, Austria, Brasil, France, Finland, and some other countries. Up to now, this technique does not seem to have a wide spread application. Indeed it can only apply cases of deafness still presenting sufficient neural remnants to transmit the message. Moreover, the patient must be totally deaf( quasi­ complete loss of har cel...

Postoperative imaging of the multichannel cochlear implant.

PURPOSE To present the postoperative radiographic appearance of the multichannel cochlear implant and to suggest criteria for the radiographic evaluation of postimplant patients. METHODS One hundred forty-one patients, 73 female and 68 male, had multichannel cochlear implants inserted. One hundred thirty-five intraoperative radiographs, 31 postoperative radiographic examinations, and 10 posto...

Averaged electrode voltage testing to diagnose an unusual cochlear implant internal device failure.

This paper describes an unusual Clarion 1.2 cochlear implant failure in order to demonstrate the need for the clinical availability of electrode voltage testing. The case report describes a patient with a Clarion 1.2 cochlear implant who exhibited poor auditory progress in spite of grossly normal impedances and electric field testing, and an appropriate educational and psychosocial environment....

A multicenter study of device failure in European cochlear implant centers.

OBJECTIVE To evaluate the failure rate of cochlear implant systems across a range of European implant centers. STUDY DESIGN Retrospective review. SETTING Tertiary care cochlear implant centers in Europe. MATERIAL AND METHODS A postal questionnaire was designed to assess the incidence and mode of total device failure and was sent to 34 European clinics. RESULTS Twenty seven (79%) centers...
