BAHA Fitting

BAHA Fitting

When Should You Consider Bi-Modal Fitting?

Bone-anchored hearing aid is a surgically implanted system that is based on bone conduction. Basically, it is suited for people having a conductive hearing loss, unilateral hearing loss, and partial deafness. It sends sound vibration directly to the inside ear via skull bone. In this way, problems in the middle ear and ear canal problems can be prevented.

Why should you Consider Bone-Anchored Hearing Aid (BAHA)?

Bone-anchored hearing devices stop sound waves and signals from reaching the inside ear through the typical(normal) acoustic pathway. There are several situations for which you need to embrace Bone-anchored hearing devices, such as:

  • Chronic Ear Infections
    People having chronic ear infections often face continual drainage from their ears. Placing a normal hearing aid in the ear may aggravate the infection by plugging up the ear canal. Bone-anchored hearing aid never occludes the ear canal. It is an ideal solution for people having an excessive allergy to the materials that can be fabricated by the conventional hearing aids.
  • Malformations of the Outer or Middle Ear
    Conductive hearing loss can be caused by malformations of the ear including narrowing of the ear or malformed absent external ear. Most of these malformations come by birth. Since a bone anchored hearing aid is in direct contact with the skull bones, it is able to deliver sound vibrations directly to the inner ear.
  • Single-Sided Deafness
    Single Sided Deafness or SSD is a complication for which an individual can lose all his hearing power in one ear while another ear remains the same-normal. SSD makes it quite difficult to decide which direction the sound is coming. It also makes one unable to understand speech in a noisy surrounding.

How does it Work?

Bone-anchored hearing aid is composed of three parts- titanium implant, a sound processor and an external connecting element. Placing a bone anchored hearing device is an outpatient process that takes maximum one hour. A small titanium implant of 3-4 millimeters is inserted into the ear. After implantation, it uses bone vibration as a natural path through which sound is delivered to the inner ear.

A Final Takeaway

The best thing about bone anchored hearing device-aids(-BAHA) is that the device is able to bypass the outer and middle ear malformations. To reap the maximum benefits of a bone anchored hearing device, you should consult an experienced doctor(audiologits) first of all.
