Indications
- hearing loss due to
- chronic ear infection
- congenital atresia of the auditory canal*
- deafness due to acoustic neuroma
- mild to severe unilateral conductive hearing loss[1]
- FDA-approved for
- sensorineural hearing loss#
- conductive hearing loss
- mixed hearing loss
* useful if ear canal unable to tolerate hearing aid
# may not be useful for sensorineural hearing loss
Procedure
- a titanium implant is placed into bone allowing bone conduction to stimulate the cochlea directly, thus bypassing the outer & middle ear
- vibrations through the skull are sent by the titanium implant to the cochlea which stimulates the nerve fibers of the inner ear
- patients can test the BAHA prior to surgery
