Hearing Loss: A Novel Approach To Bone-Anchored Hearing Aids (BAHA)

by FloridaENT AndAllergy Florida E.N.T & Allergy

The bone-anchored hearing aid (Baha) is a method for addressing hearing loss that is surgically implanted. The technique, which has been in use since 1977, involves direct bone conduction, in which sound is transmitted through the bone instead of the middle ear. In 1996, the FDA approved it for use as a medication for mixed and Conductive Hearing Loss in the United States.

Conductive loss occurs when the volume of sound has been unable to flow adequately from the external canal of the ear to the internal ossicles of the ear and the eardrum.

Multiple ear infections, allergies, and moisture in the ear, especially owing to cold, entry of foreign substances in the ear, Eardrum Perforation, and other factors can cause conductive loss.


Functions of BAHA

The Baha is made up of three primary components: an implant, an external abutment, and a sound processor. These three components work together to improve natural bone transmission and create a route for sound to reach the inner ear without passing through the external auditory canal or the middle ear.

A surgical process is used to install the implant. With time, it blends in with the original skull bone.

The sound processor sends soundwaves through the outside abutment, which then transmits the vibrations to the bone. The inner ear nerve fibers are stimulated by the vibrations of the skull and inner ear, allowing hearing.


Ideal Patient For Baha

For patients who have lost their hearing due to persistent ear infections or congenital middle ear problems, the Baha is a great alternative. To access the inner ear, the equipment goes around the outer and middle ear. The Baha can be used effectively as long as the inner ear is undamaged and functioning appropriately.

It is also ideal for those who have problems adapting to the sensation of a typical hearing aid. It not only helps with pain issues, but it can also aid with input and amplification issues.


Suitable For Patients With One Ear Deafness

Among the most beneficial aspects of the Baha is that it aids patients who have a deaf ear. The FDA approved the Baha as a treatment for unilateral deafness to improve their hearing.


Best Characteristics of Baha

The Bone Anchored Hearing Aid is safe, convenient, gentle, and frequently invisible after correctly placed for those who have issues with their outer and inner ears, deafness with one ear. The Baha won't fall out or loosen as other hearing aids do occasionally.
