[Bone-anchored hearing aids and active middle ear implants].

This review is concerned with hearing implants, which are used in patients with hearing loss, who cannot be treated successfully with a conventional hearing aid. Among these implants, bone-anchored hearing systems (BAHS) can be used for conductive or mixed hearing loss, while active middle ear implants primarily are reserved for sensorineural hearing loss. For BAHS, active transcutaneous implants may replace percutaneous implants as a future first choice.
