The restoration of hearing in neurofibromatosis type 2.

Central electrical stimulation of the auditory pathway can allow hearing in patients suffering from deafness localized in the auditory nerve. Developments in a multi-channel auditory brainstem implant based on the Nucleus Mini 22 Cochlear implant with transcutaneous signal transmission is discussed. The devices have been implanted in nine European patients suffering from Neurofibromatosis Type 2. Preliminary speech perception results and patient satisfaction are encouraging, and the data presented include some limited open speech recognition.

Cochlear Implants

An unusual cause of cochlear implant failure.

We present a cochlear implant failure previously unidentified and unreported. Following successful implantation and activation of a Cochlear Mini 22 system, a distressing barrage of crackling noises was heard by the patient despite repeated programming with threshold and comfort level adjustment. The implant soon became nonfunctional and integrity testing showed deficient electrical responses and abnormal surface measured wave forms. Investigation of the explant, following reimplantation with an identical system, showed a defective trim capacitor, an electric component of the internal circuit in the stimulator. Paired Student's t-test showed a marginally significant increase (p = 0.047) in effective threshold level and a highly significant decrease (p = 0.0002) in maximum comfort level for the second implant compared to the first implant.
