Typical hearing aids relay information about sound through air and rely on a properly functioning middle ear. However, bone as well as air can also conduct information. The Baha system is an amplification option that offers direct bone conduction for those patients with a conductive hearing loss, mixed hearing loss or single sided deafness.
A processor worn behind the ear detects sound vibrations and transfers it to the implant allowing it to completely bypass the outer and the middle ear and directly stimulate the inner ear. While young children will wear this processor on a headband, older children and adults may have an abutment surgically placed in the bone behind the ear. This abutment, which is made of titanium, will osseointegrate, or become a permanent structure of the bone.
