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