*2.6.1 History*

Hitselberger and House performed the first implantation of an ABI in 1979 [28]. It was a single spherical electrode implanted adjacent to the cochlear nucleus following removal of bilateral vestibular schwannomas of a patient with Neurofibromatosis Type 2 (NF2). In 1992, Cochlear Ltd. in conjunction with the Huntington Medical Research Institute developed the first multichannel electrode array devices which have, in most cases, provided patients with greater benefits than the earlier devices [29].
