The Bone-Anchored Hearing Aid (BAHA) service is run in conjunction with the Ear, Nose & Throat (ENT) Department.
It consists of a small titanium screw and a connecting abutment that is anchored into the bone behind the ear (temporal bone). A small box containing the contents of the hearing aid is then able to clip on and off the abutment, which will sit flush with your skin.
BAHA is a type of hearing aid suitable for people who are unable to wear a conventional hearing aid successfully. These fall into three categories.
- A conductive hearing loss. This means that sound cannot travel freely through the ear canal and middle ear to the cochlea. For example, this may be due to an eardrum perforation, mastoid cavity or chronic infection.
- Abnormalities with the external part of the ear, ear canal or middle ear.
- Complete hearing loss.
BAHA’s are only suitable for patients with reasonable inner ear hearing. Click here to find out more.
