baha_parts The BAHA is divided into 3 components:

1) Sound Processor: The sound processor, which sits behind the ear, picks up sound through a microphone. The sound is amplified and converted into sound vibrations.

2) Abutment: The abutment, or connector, links the sound processor and a titanium implant, transferring the sound vibrations from the sound processor to the implant.

3) Titanium Implant: The titanium implant is a small fixture surgically placed behind the ear in an outpatient procedure. It naturally fuses with bone and transfers sound vibrations to the inner ear.

Where is the BAHA placed on my child with microtia?

The BAHA is placed behind the ear as close to the ear as possible without actually touching the ear. If there is any contact, there may be sound interference.


How does a Bone – Anchored Hearing Aid ( BAHA ) work on children with microtia?

1) Bone, like air, conducts sound. Conventional hearing aids rely on air conduction to send sound from the outer ear, through the middle ear, and to the inner ear.
2) The BAHA system bypasses the outer and middle ear using bone conduction to send sound to the functioning inner ear. So, even with the ear affected with microtia, the BAHA system can send sound vibrations directly through bone to the inner ear (cochlea).
3) Once sound reaches the inner ear, the sound vibrations are converted into electrical impulses by tiny hair cells inside the cochlea.
4) These impulses travel to the brain, allowing the child with microtia to perceive sound naturally.

How does Cochlear’s New “BAHA 4 Attract” System work?BahaBaha

1) A small implant made of titanium is inserted in the bone behind the ear. The implant magnet is attached and hidden beneath the skin. A sound processor is then attached to an external magnet and sound is transmitted as vibrations from the processor via the magnets to the implant, which then directs them through the bone to stimulate the inner ear. The new system avoids the need for an abutment that sticks out of the scalp. There is no need for daily cleaning.
