Auditory Brainstem Implant (ABI)



CNC Hearing and Balance Center is now offering the latest advancement in hearing technology – an auditory brainstem implant (ABI) for those unable to benefit from a cochlear implant. “Adults who lose their hearing nerves to brain tumors like acoustic neuroma and babies born without hearing nerves now can receive an ABI and receive sound stimulus similar to a cochlear implant,” said Neurotologist Moises Arriaga of CNC Hearing and Balance Center. “It is a major advance and means these people are no longer forced to live in a silent world,” he said. The auditory brainstem implant uses technology similar to that of the cochlear implant, but the ABI bypasses both the cochlea and the hearing nerve, taking a short cut to the brainstem. It provides a sense of sound when the hearing nerve is not working.  It is a surgically implanted electronic device that has two parts: an external part worn on the ear and the surgically implanted internal part. The ABI provides a sense of sound to a person who is profoundly deaf, due to retrocochlear hearing impairment.


One of the main uses of the auditory brainstem implant is for those with the condition Neurofibromatosis type 2 (NF2). Adults with Neurofibromatosis Type 2 have a disorder characterized by the growth of non-cancerous tumors in the nervous system referred to as acoustic neuromas. These tumors develop along the nerve that transmits information from the inner ear to the brain, known as the auditory nerve. The signs and symptoms of NF2 generally begin to appear during the patient’s teens or early 20s, and start with hearing loss, tinnitus, and problems with balance. In the majority of instances, these acoustic neuromas develop in both ears by the age of 30.

If you’re inflicted with NF2 or hearing loss from other disorders, the CNC Hearing and Balance Center can determine the best course of action to restore your hearing loss. Our experts can determine if you are a candidate for an auditory brainstem implant.
