BAHA
Pronunciation: BAH-hah
Also written as: BAHA — Bone Anchored Hearing Aid
Bone-anchored hearing aid that transmits sound through bone conduction via a titanium implant in the skull.
Full Definition
A Bone Anchored Hearing Aid (BAHA) is a surgically implanted hearing device that bypasses the outer and middle ear by transmitting sound vibrations directly through the skull bone to the inner ear. The system consists of a titanium implant that osseointegrates with the temporal bone, an external abutment, and a sound processor. BAHAs are indicated for patients with conductive hearing loss, mixed hearing loss, or single-sided deafness where traditional hearing aids are ineffective. The device is particularly beneficial for congenital ear canal atresia, chronic otitis media, and acoustic neuroma patients.
