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 does not involve the middle ear space which minimises this risk. The surgery takes place under local or general anesthesia.

If you're getting an Osia System, your surgeon will place the BI300 Implant behind your ear with the Osia OSI200 Implant attached to it. It 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, where it will fuse to the bone over time.

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.
