Bone conduction implants

A Bone Conduction Implant delivers sound via direct bone conduction to the inner ear, effectively bypassing the outer and middle ear. The term Bone Anchored Hearing Aid (BAHA) was used historically to describe bone conduction implants, however the term BAHA refers to a specific type and brand of bone conduction implant. A Bone Conduction Implant relies on a working cochlea to send sound to the brain. There are several bone conduction implants which may be suitable; each works in a different way. They all have a surgically inserted fixing point anchored to the skill and an external processor. The external processor converts the sound energy into mechanical movement of the implanted anchor. The fixture vibrates in the skull and so that the natural bone conduction (transmission) of sound to the cochlea can bypass the non-functioning outer or middle ear.
