The Auditory Brainstem Implant (ABI) is a modified cochlear implant intended to be used to stimulate the cochlear nucleus in the brainstem of patients who have had their eighth nerves severed during surgery for removal of bilateral neurofibromata, as in patients with NFII.
The need for this device is much less common than that for a cochlear implant, but these patients are typically totally deaf and, although the benefit is not as great on the average as that of the cochlear implant, most recipients derive significant auditory perception.

Once the incision site is well healed, and the implant is secured to the external processor and antenna, patients will begin to work with a combination of audiologists, speech therapists, otolaryngologists (ear, nose, and throat doctors), and possibly other specialists in order to learn to "hear" and process sound using the cochlear implant.
Individual results in using cochlear implants vary widely, and are influenced by the condition of the hearing nerve prior to surgery, the patient's mental abilities, the specific device being used, the length of time the patient was deaf, and the surgery itself.
