Auditory brainstem implant

An auditory brainstem implant (ABI) is a surgically implanted electronic device that provides a sense of sound to a person who is profoundly deaf, due to retrocochlear hearing impairment (due to illness or injury damaging the cochlea or auditory nerve, and so precluding the use of a cochlear implant). In Europe, ABIs have been used in children and adults, and in patients with neurofibromatosis type II. == History == The auditory brainstem implant was first developed in 1979 by William F. House, a neuro-otologist associated with the House Ear Institute, for patients with neurofibromatosis type 2 (NF2).
