What is BAHA Mapping?
A Bone Anchored Hearing Aid (BAHA) is a hearing device that utilizes direct bone conduction to transmit sound. This hearing aid is surgically implanted behind the ear to bypass the auditory canal and middle ear. It takes advantage of the bones’ natural conductive abilities by sending sound vibrations directly to the inner ear.
The BAHA system is an option for people who cannot benefit from an in-the-ear or behind-the-ear hearing aid. They typically have conductive hearing loss, mixed hearing loss, single-sided deafness or frequent ear infections. It has been used for people in all age groups including children as young as one-year-old.
Setting Up a BAHA System
The BAHA system is comprised of a titanium implant, external abutment and sound processor. The implant is surgically placed behind the ear and gradually fuses with the skull bone over several months in a process called osseointegration. After this process, the external components can be fit and programmed by an audiologist.
The programming is called MAPping. MAPs are programs that help customize the implant to the user. Patients with implants will get the most optimized use from frequent and high quality mapping. BAHA mapping consists of beeps that will help the audiologist adjust the implant’s processors.
