Baha – The Implantable Hearing Device

The Baha system is an innovative technology that has been approved by the Food and Drug Administration to treat hearing loss. The Baha offers an alternative method for achieving sensitive hearing by the way of Bone Conduction. The Baha works on a principle of efficient coupling of the sound processor to the underlying bone through 1) a small connector across the skin, and 2) an implant that directly bonds with the underlying bone – an osseointegrated implant. The Baha is currently the only device that works through direct bone conduction.

For more information about direct bone conduction, please visit www.cochlear.com.

What is the Baha system?
The system consists of three components: the titanium fixture, the abutment and the external sound processor.

How does Baha work?
Baha is a technology that combines a sound processor with a small titanium fixture implanted behind the ear. This unique system allows the bone to transfer sound to a functioning cochlea (See How the Ear Works) rather than via the middle ear – a process known as direct bone conduction.

How will the titanium fixture be implanted in my ear?

bahaYour doctor will perform minor surgery to place the Baha behind your non-functioning ear. The surgery is completed as an outpatient procedure.

How do I know if Baha will work for me?
Only your doctor, together with your audiologist, can determine if you are a good candidate for Baha. You will have an opportunity to try the Baha processor connected to a headband during your appointment. This will provide some sense of what sound would be delivered through bone conduction.

Are you a good candidate for Baha?
Possible Baha candidates may have hearing loss from:

  • Malformation of the ear canal or middle ear
  • Infection of the ear canal resulting in chronic draining ears
  • Chronic otitis media
  • Congenital atresia
  • Cholesteatoma
  • Middle ear dysfunction/disease
  • Sudden hearing loss
  • Acoustic neuroma
  • Meniere’s disease

What Baha sound processor is right for me?
There are currently 3 Baha sound processors.

  • The Cordelle
  • The Divino
  • The Intenso

Your audiologist will assist you with this decision making process. The device selection must be made prior to your surgery for proper device ordering and billing. You will also need to select the appropriate color option to best match your hair color.
