BAHA (Bone Anchored Hearing Aid)

 

Bone Anchored Hearing Aids (BAHA) use the same principles of bone conduction as regular Bone Conduction Hearing Aids and send sound directly through bone to the inner ear.  They are a newer technology and can be more comfortable and discreet.

Bone Anchored Hearing Aids have 3 components – a titanium implant or screw that is surgically implanted in the bone of the skull  just behind the ear, an abutment that is attached to the implant, and a sound processor (the external part of the BAHA).  The abutment is the connecting piece that joins the sound processor to the implant. 

Sounds are picked up by the sound processor, which turns them into vibrations.  The processor is connected to the embedded implant via the abutment.  The abutment transfers the amplified sound vibrations from the sound processor to the implant.  The implant then transfers the sound vibrations through the skull bone directly to the Cochlea using bone conduction and bypasses the source of the conductive hearing loss caused by atresia. 

The minimum age fro Baha implantation in Australia is 5 years of age.

Baha Softband

 

 

Young children have soft bones that are not suitable for a Baha implant.  A baha Softband is a soft elastic headband with a plastic connector sewn in.  A Baha sound processor easily attaches to the connector.  The softband holds the sound processor against the bone behind the ear (mastoid) or any other bony location of the skull.  The Baha softband can be used from 6 weeks of age. 

Baha Softbands can also be used by people of any age.  They can be used to trial a Baha before making the decision to proceed with surgical implantation.
