Osseointegrated Devices

Osseointegrated devices, also known as bone anchored hearing aids, consist of a titanium implant, an external abutment and a sound processor. Like cochlear implants, the osseointegrated devices bypass damaged hair cells in the auditory canal and middle ear, transmitting sound vibrations through the external abutment to the titanium implant, which naturally integrates (“ossifies”) with the skull bone over time. The bones of the skull act as conductors, transmitting these sound vibrations to the inner ear, where the nerve fibers responsible for hearing are stimulated. Osseointegrated devices are especially useful for patients with conductive hearing loss and single-sided deafness.
