Bone-Anchored Hearing Aids (BAHA)

BAHAs are a type of hearing aid which transmits the sound through bone conduction via an abutment inserted into the skull behind the ear. Sound is detected by a sound processor which attaches to the abutment and transmits the signal through the skull, cochlear, auditory nerve and to the brain, bypassing the outer and middle ear. BAHAs are suitable for people with conductive hearing losses, unilateral losses, mixed losses or recurrent middle ear problems.

In order to be considered for a BAHA, a full assessment of your hearing and lifestyle is required. If you are found to be a suitable candidate, a trial of the technology will be offered which will involve a processor attached to a headband. Fitting of BAHAs include a surgical procedure in which a titanium implant with an abutment is placed into the skull behind your ear. Once healed, the sound processor is attached to the abutment and fine-tuned to your hearing requirements. Having a BAHA fitted is a lifelong commitment, and must be kept clean and hygienic by cleaning the abutment daily, and looking after the sound processor.
