Bone-Anchored Hearing Aids (BAHA)
Bone-anchored hearing aids (BAHA) are an alternative for people with conductive hearing loss who need amplification but have problems with chronic ear infections that cause a constant draining ear. They are also an alternative for those who have been born with an incomplete ear canal.
The BAHA is a combination of a sound processor attached to a small titanium implant or fixture which is placed in the bone behind the ear during a routine surgical procedure.
The bone acts as a pathway for sound to travel to the inner ear without involving the ear canal. With the BAHA there is no occlusion of the ear canal to aggravate infammation.
As the system is based on osseointegreation, using a fixture to attach the sound processor, there is no pressure from the transducer against the skin, thus avoiding the headaches and soreness often associated with conventional bone conductors.
