Auditory Brainstem Implants
Auditory brainstem implants (ABIs) are currently indicated for patients with neurofibromatosis type 2 (NF-2) tumors involving both vestibulocochlear nerves. The ABI helps bypass the damaged cochlear nerves and stimulates the cochlear nucleus in the brainstem directly thereby restoring auditory sensation. The implant is usually placed in the lateral recess of the fourth ventricle after tumor res...
متن کاملAuditory Brainstem Implants 34 CHAPTER
The auditory brainstem implant (ABI) for patients was originally developed for patients with neurofibromatosis type 2 (NF2) in order to electrically stimulate the cochlear nucleus complex. Drs. William House and William Hitselberger first used the ABI in such a patient in 1979, who continues to use it daily. Patients with NF2 usually have bilateral vestibular schwannomas (VS) necessitating tumo...
متن کاملConducting polymer electrodes for auditory brainstem implants.
The auditory brainstem implant (ABI) restores hearing in patients with damaged auditory nerves. One of the main ideas to improve the efficacy of ABIs is to increase spatial specificity of stimulation, in order to minimize extra-auditory side-effects and to maximize the tonotopy of stimulation. This study reports on the development of a microfabricated conformable electrode array with small (100...
متن کاملHistory of cochlear implants and auditory brainstem implants.
Cochlear implants have evolved during the past 30 years from the single-electrode device introduced by Dr. William House, to the multi-electrode devices with complex digital signal processing that are in use now. This paper describes the history of the development of cochlear implants and auditory brainstem implants (ABIs). The designs of modern cochlear and auditory brainstem implants are desc...

A. Member has bilateral severe to profound sensorineural hearing loss determined by a pure tone average of 70 dB or greater at 500 Hz, 1000 Hz, and 2000 Hz; and B. Member has limited benefit from appropriately fitted binaural hearing aids. Limited benefit from amplification is defined by test scores of 40 % correct or less in best-aided listening condition on open-set sentence cognition (e.g., ...
