Bone anchored hearing aids (BAHA)

Bone-anchored hearing devices are used primarily for conductive hearing losses or single-sided deafness. They are also an option for improved hearing in patients with congenital ear malformations or chronic ear disease. A titanium fixture is implanted in the postauricular (behind the ear) area. An external sound processor is attached to the abutment and a microphone picks up the sound, which then vibrates the bone in the skull by means of the fixture. The sound is transmitted directly to the inner ear on the side with conductive hearing loss or the better hearing ear in single-sided deafness.
