Hearing solution for those with conductive / mixed or single sided hearing loss.
- by air conduction via the ear canal and middle ear to the inner ear
- by bone conduction where vibration bypass the outer and middle ear and conduct to the inner ear directly.
BAHA system uses a process called direct bone conduction. A small titanium implant is placed in the bone behind the ear where it osseointegrates with living bone. Osseointegration takes about three months for adults and six months for children. Once this has taken place an abutment is attached to the fixture and a sound processor is clipped on. Sound is picked up by the external processor and is conducted directly through the bone to the inner ear.
For patients with single sided profound hearing loss, the Baha system is placed on the deaf side and the device picks up sound and conducts it to the working cochlea of the good ear. This allows patients with single sided hearing loss to hear sound from both sides where previously he can only hear it on one side.
Since the Baha system does not have any component in the ear canal, for those with recurrent ear infections it can leave the ear canal open which allow the ear to dry out and reduce the further incidence of recurrent ear infections while still providing amplification.
