International Licensing Examination (ILE) Practice Test

Which of the following statements accurately describes BAHA technology?

1. Used for patients with perfect ear anatomy

2. Includes a speaker housed inside the concha

3. Allows sound to be transmitted through the bones of the skull

4. Is limited to external ear fittings only

The correct answer is: Allows sound to be transmitted through the bones of the skull

The statement that accurately describes BAHA technology is that it allows sound to be transmitted through the bones of the skull. BAHA, or Bone Anchored Hearing Aid, works by vibrating the skull bone directly, which stimulates the cochlea in the inner ear. This bypasses the outer and middle ear, making it a suitable solution for individuals who may have conductive hearing loss or problems with their ear anatomy that prevent conventional hearing aids from being effective. The understanding of the anatomical context is important here, as BAHA technology is particularly valuable for patients who may not have 'perfect ear anatomy.' Instead, it addresses specific auditory challenges without relying on the typical pathways of sound transmission through the outer and middle ear. Also, BAHA devices do not involve speakers housed inside the concha, nor are they limited to external ear fittings only. They are surgically implanted, allowing them to transmit sound efficiently through the bone structure, opening up treatment options for many individuals with hearing difficulties.
