Bone-anchored hearing devices are used primarily for conductive hearing loss or single-sided deafness. They are popular for hearing rehabilitation in patients with congenital ear malformations or refractory chronic ear disease. A titanium fixture is implanted in the postauricular area. An external sound processor is attached to the abutment at will. A microphone in the processor, which vibrates the bone in the skull by means of the fixture, picks up sound. The sound is transmitted directly to the inner ear on the side with conductive hearing loss or better sensorineural hearing than the other.
