Bone Conduction Implant Devices
Bone conduction implants (BCIs) are semi-implantable devices for the treatment of hearing losses in patients who either cannot wear or underperform with conventional hearing aids. These devices have to be surgically implanted, are based on the principle of osseointegration, and work by enhancing natural bone conduction. Since their first introduction in 1977, they have evolved in their external design and functionality. Even the surgical technique has undergone several modifications. Today, they are available as percutaneous and transcutaneous devices.
