Bone Anchored Hearing Aid (baha) - What You Need To Know
Bone anchored hearing aids are also known as BAHA. These are surgically implanted hearing aids used to treat hearing loss. BAHA differs from other hearing aids as it uses direct bone conduction to transmit the sound.
This is where the sound travels through the bone. This isn't actually a new idea, it has been possible since 1977. It wasn't until 1996 that the FDA approved BAHA for use in the United States.
The BAHA has three main parts. There is an implant, an external abutment and a sound processor. These three parts work together to enhance natural bone transmission and provides a pathway for sound to enter the inner ear that bypasses the external auditory canal and middle ear.
The implant itself is made out of a small piece of titanium. This is physically implanted underneath the skin on top of the skull bone.
The sound processor is responsible for transmitting the sound vibrations through the external unit, this then causes the bone to vibrate. The vibration of the skull causes the nerves to become stimulated which allows the patient to hear.
Who can use the BAHA?
The BAHA is suitable for people with difficulty in hearing caused by ear infections or congenital middle ear defects. This hearing aid is capable of bypassing the outer and middle ear, to reach the inner ear.
In order for this hearing device to utilized well, the only thing that needs to be working correctly is the inner ear. If you suffer from ear infections on a regular basis, the BAHA does not affect the condition, as conventional types of hearing aid often do.
Bone anchored hearing aids are fantastic for people who do not feel comfortable wearing conventional hearing aids. The BAHA also overcomes problems caused by amplification and feedback issues.
Is the BAHA helpful for people with deafness in a single ear?
One of the best things about the BAHA is that it helps those with a deaf ear. Prior to BAHA, people with unilateral deafness did not have many satisfactory options for improved hearing. Recently, the BAHA was cleared by the FDA as a solution for unilateral deafness.
The BAHA hearing aid is placed on the side of the deaf ear. It transmits sounds from the deaf ear to the normal ear, resulting in a sensation of hearing in the deaf ear.
What are the best features of the BAHA?
Bone anchored hearing aid can address the needs of people who suffer from problems with both the outer and middle ear, and deafness in a single ear.
The BAHA is much more comfortable than many other types of hearing aids. Once implanted, the BAHA is completely unnoticeable. It can't fall off accidentally, and there is no need to re-fit it.
About the author:
Only one out of five people who could benefit from a hearing aid actually wears one. While the BAHA hearing aid is suitable for those with hearing loss in one ear, there are other types of hearing aids to suit almost every type and degree of hearing loss, and budget.
