A Bone Anchored Hearing Device (BAHD) is an implanted hearing device for the treatment of hearing loss, working through bone conduction. The device directly stimulates the inner ear via the bone, thus bypassing the outer ear canal and the middle ear.
The device has two components:
•    An implant implanted surgically into the bone behind the ear.
•    A hearing processor attached to the implant.

How does it work?
1.    The BAHD processor absorbs the sound, raises the volume and converts it into vibrations.
2.    The implant collects the vibrations and transfers the sound via the bone directly to the inner ear.
3.    The sound reaches the cochlear (the hearing organ), which stimulates the hearing nerve.
4.    The hearing nerve transports the sound to the brain, where it is interpreted.
In a case of one-sided loss, the processor sends the sound via the skull from the side that doesn’t hear to the inner ear of the side that does, so the patient is aware of sounds coming from all directions.

Benefits of BAHD
•    Improvement in understanding speech in both quiet and noisy surroundings.
•    Improvement in identifying the source of sounds.
•    The quality of the sound is better in comparison to regular hearing devices (less squeaking and distortion.)
•    The ear canal remains ventilated, which helps reduce problems caused by chronic or allergic ear infections. In one-sided loss, the device enables hearing awareness in the poorer ear.

Who is BAHD good for?
Adults or children suffering from:
•    Conductive or mixed hearing losses. This includes patients with chronic ear infections, congenital undeveloped ear canals, etc., who cannot derive benefit from or wear regular hearing devices.
•    One-sided hearing losses. 
The operation is not authorized for children under 5. For these children, the processor connects to an elastic band or bow worn around the head until they are able to undergo the operation.
Patients with conductive, mixed or one-sided losses can also be eligible for a system that includes a magnet instead of the conventional implanted piece.
At the evaluation stage, we will perform a regular hearing test and if necessary, a hearing test with hearing devices and with the BAHD system. Anyone eligible for an operation must see an ENT doctor first.
