Symptom Timeline Preceding Cochlear Implant Failure

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...

Facial Nerve Stimulation in Cochlear Implant Patients

Cochlear Implant

Cochlear implants are first true bionic sense organs Like human inner ear hair cells they convert mechanical sound energy into electrical impulses. Cochlear implants are not hearing aids which merely amplify mechanical sound waves and increase their energy content Otter et al have shown that in the normal auditory nerve in young people there are approximately 35,000 nerve fibres; they concluded...

Cochlear implant failure: imaging evaluation of the electrode course.

Cochlear implant (CI) is an electronic device used to rehabilitate patients with sensorineural hearing loss. The intent of this review is to demonstrate the normal position of the electrode on computed tomography (CT) and contrast this with various examples of the electrode malpositioning. Post-implantation CT is performed to localize the cause of implant failure in patients in which radiograph...
