What happens during bone conduction implant surgery?

Cochlear has two types of bone conduction systems – the Osia® System and the Baha® System. The surgeries for each of these systems are routine operations.

Unlike reconstructive middle ear surgeries that risk damaging your existing natural hearing1, implantation with a bone conduction implant does not involve the middle ear space and won't cause any loss of the remaining hearing you may have in your ear.

If you're getting an Osia System, your surgeon will place an Osia implant under the skin behind your ear, attached to the bone via another small titanium implant (BI300). This implant will fuse to the bone over time through a natural process called osseointegration.

If you're getting the Baha System, your surgeon will place the small BI300 Implant behind your ear, and attach either an abutment or implant magnet to the BI300, depending on your connection type.

After surgery, medical staff will apply a protective dressing to your implant area.

How long does a bone conduction implant operation take?

Bone conduction implant surgery is typically an outpatient procedure that takes less than an hour.

"To have such a simple procedure and get my hearing back to this level? I'd do it again without hesitation."
