Implants
Bone conduction (BAHA): Osia and Baha Start
For conductive or mixed hearing loss, or deafness in one ear, bone conduction sends sound through the bone straight to the inner ear. Many ENT surgeons call this a BAHA, a bone anchored hearing aid. You can try it first with no surgery on Baha Start, free at our Care Centres, then move to the Osia implant.
