Informationsfilm: Benförankrad hörapparat

A bone anchored hearing system, BAHA, uses a sound route that does not pass the ear canal and the middle ear, as occurs with conventional hearing aids. Instead the ability to conduct the sound in the bone of the skull is used. Bone can like the air cause vibrations.

For a child with a hearing loss, this is another opportunity to hear sounds. The sound takes a detour around the damaged area and stimulates the inner ear (cochlea) through direct bone conduction. A condition for hearing with BAHA is that the inner ear, auditory nerve, auditory pathways and brain can receive and interpret sound information.

How it Works:

• The sound processor picks up sound waves in much the same way as a conventional hearing aid.

• Instead of sending them through the ear canal, it is transformed into sound vibrations. An abutment between the processor and implant convert the signal into mechanical vibrations.

• The titanium implant is through surgery located behind the ear. The titanium Implant and the bone of the skull is osseointegrated. The vibrations travels directly to the inner ear, bypassing any problems in the outer and/or middle ear.
