A bone anchored hearing aid, or BAHA is an implantable device used to improve hearing by stimulating the inner ear through the bone. BAHAs can improve hearing in patients with less severe cases of conductive or mixed hearing impairment. It is ideal for patients who are not candidates for regular hearing aids because of a physical deformity, frequent ear infections or narrow ear canals.
A bone anchored hearing aid placement procedure takes less than an hour to perform on an outpatient basis, using local anesthesia for adults and general anesthesia for children. Patients can return home the same day. During the initial procedure, only the titanium screw and abutment are placed, while the hearing aid is implanted during a second procedure three to six months later. This ensures that the titanium becomes integrated into the bone for long-lasting correction.
Aural rehabilitation for those with cochlear implants or bone anchored hearing aids generally includes learning strategies to communicate more effectively in conversation as well as how to handle distracting background noise.
