Bone Anchored Hearing Aid (BAHA) is a device surgically implanted to help people suffering from a loss of hearing. Most conventional hearing aids transmit sound through air conduction. The BAHA device is suitable for conductive or mild-moderate mixed hearing loss.
Problems with hearing in the middle or outer ears can be helped with the BAHA device. The sound waves received by the BAHA device bypass the middle ear and get delivered straight to the functioning cochlea in both ears.
A BAHA device comprises of two parts:
The implant is embedded in the bone. The processor, which remains outside, is attached to the implant. There is a microphone on the processor that picks up sounds. The sounds are passed on to the implant. The implant vibrates which triggers the Cochlear. You can consider wearing a BAHA implant if other conventional hearing aids do not work for you. BAHA implants are also given to people with collapsed or irritated ear canals.
Cochlear Implant Surgery
A complex, small electronic device that helps hearing in people with severe hearing loss or deafness is used in the Cochlear Implant Surgery. The cochlear implant comprises of an external piece behind the ear and another piece that is surgically implanted under the skin. A cochlear implant comprises of four parts:
The implant does not cure deafness; it only gives you a useful portrayal of sounds in the environment and considerable aid in understanding speech.
The surgery is done in the following way:
