Cochlear Baha System
The Baha® is a surgically implantable system for treatment of hearing loss that works through direct bone conduction. The procedure was approved by the FDA in 1996 as a treatment for conductive and mixed hearing losses in the United States and in 2002 for its use for the treatment of unilateral sensorineural hearing loss or single-sided deafness. It is covered by some insurances including Medicare and Medical Assistance. Our Clinic Manager and Cochlear will work with you to determine your insurance benefits.
Baha® is used to help people with chronic ear infections, congenital external auditory canal atresia and single sided deafness that cannot benefit from conventional hearing aids. The system is comprised of three parts: the titanium fixture which in implanted into the bone; the connecting abutment; the digital sound processor. New implant candidates may be offered the new attract system which eliminates the connecting surface abutment and replaces it with a magnetic system.
Part of the system is surgically implanted and allows sound to be conducted through the bone rather than via the middle ear - a process known as direct bone conduction.
Baha® 4 Attract System
How the Baha 4 Attract System works: 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.
For extra comfort, the Baha SoftWear™ Pad attaches to the external magnet, adapts comfortably to the shape of the head, and distributes pressure evenly.
An invisible connection to better hearing
The new BAHA 4 Attract system offers invisible connection to hearing and better hearing performance The new BAHA processor offers Smarter hearing and wireless freedom The Baha Sound Processor magnets are available in different strengths to suit individual patients and lifestyles.
Who Can Benefit From a BAHA?
Patients with chronic middle ear conditions or outer ear problems or congenital defects of the ear who can’t wear hearing aids may be candidates for a BAHA as long as one ear has a cochlea that can hear at a moderate hearing level or better. A second category of candidates are patients with “single sided deafness”. This includes patients who have lost all or most hearing in one ear, in which a conventional hearing aid is not helpful, but have good hearing in the other. A BAHA may provide an excellent hearing alternative for patients who cannot benefit from a traditional hearing aid, or in other words, for an ear that is “un-aidable” with a conventional hearing aid. BAHA is FDA approved for children over the age of 5. For children under the age of 5, a BAHA is available with an adjustable soft head band.
The Baha system, which is based on bone conduction, utilizes a titanium implant, which is placed in the skull bone behind the non-functioning ear. An abutment connects the sound processor with the implant in the bone. This creates direct (percutaneous) bone conduction. In contrast, traditional bone conductors connect indirectly to the bone through unbroken skin (transcutaneous) and work by exerting pressure against the skull.Direct bone conduction, provided by Baha, may give improved access to sound when compared to traditional bone conductors because sound is not weakened when passing through the skin, muscle and fat covering the skull.
