Bone anchored hearing aids (aka baha hearing aids) are specialized tools to help adults and children with specific types of hearing loss. They can be used without surgery in infants and young children but require surgical implantation for maximum benefit. In some instances they offer significant advantages over conventional hearing aids.

Who is a candidate?

  • Infants
    • Can be worn with a headband prior to implantation
  • Children over 5
    • Eligible for implantation
  • Adults

What types of hearing loss does it treat?

  • Single Sided Deafness
    • Total hearing loss in one ear with normal to near normal hearing in the other ear
  • Conductive Hearing Loss
    • Unilateral or Bilateral
    • Often times the result of surgery or chronic infection
    • Highly effective for children born without an ear canal (Atresia)

THE SYSTEM: Bone conduction hearing devices are designed to use your body’s natural ability to transfer sound through bone conduction. The sound processor picks up sound, converts them into vibrations, and sends them through your skull bone, directly to your inner ear. This bypasses any problems in your ear canal or middle ear.

A bone conduction hearing device consists of three parts:

  1. A small (3 or 4 mm) titanium implant that sits in the bone behind the ear
  2. A subcutaneous implant or an abutment that juts out through the skin
  3. A sound processor

The sound processor connects easily to the abutment with a simple click. Whenever you need to remove it – prior to showering and sleeping etc – just click it off again.

How it works: The sound processor picks up sound waves in much the same way as a conventional hearing aid. But instead of sending them through your ear canal, it transforms them into sound vibrations and sends them, via the abutment and implant, through your skull.In this way the vibrations travel directly to your inner ear, bypassing any problems in your outer and/or middle ear.

Single sided deafness: As sound via bone conduction is always transmitted to both ears, a bone conduction hearing device can also benefit people with single-sided deafness. It picks up sound on the deaf side and transfers it to the good ear.
