The BAHA — Direct Stimulation of the Temporal Bone

  • Anders Tjellström


Despite modern development in ear surgery many individuals hard of hearing need a hearing aid. The most common type is one that delivers the amplified sound through the external ear canal. There are however conditions where this is not possible. The most obvious situation is in the congenital defect where there are no external ear canals. Another condition is in chronic middle ear infection. If there is a hole in the tympanic membrane the ear may drain during upper respiratory infections or if the patient get water in his/her ear. Some ears drain when the ear canal is occluded with the ear-mould of a hearing aid. Chronic inflammation of the ear canal may also make it impossible to use a conventional air conduction hearing aid.
