The Baha System, an Osseointegrated Implant for Hearing

The Baha system utilizes direct bone conduction, which allows the bone to transfer sound to a functioning cochlea – thereby bypassing the middle ear. This unique hearing treatment is the only system of its kind cleared by the Food and Drug Administration (FDA) to treat hearing loss.

One reason the Baha system works so well is due to its simple design. The Baha system combines a sound processor with an abutment and a small titanium implant. The implant is placed behind the non-functioning ear. Surgery is minor, and Baha recipients report a wide range of advantages over other hearing devices.

The Baha system, which is based on bone conduction, utilizes a titanium implant, which is placed in the skull bone behind the ear. An abutment connects the sound processor with the implant in the bone. This creates direct (percutaneous) bone conduction. In contrast, traditional bone conductors connect indirectly to the bone through unbroken skin (transcutaneous) and work by exerting pressure against the skull.

Direct bone conduction, provided by Baha, gives improved access to sound when compared to traditional bone conductors since sound is not weakened when passing through the skin
