Osseointegrated Auditory Devices

Bonebridge is an active bone conduction device that consists of a bone conduction-floating mass transducer (BC-FMT) and magnet internally and an audio processor externally. Surgery for implantation can be performed under local anesthesia but requires surgical planning for adequate bone depth for the BC-FMT well. Bonebridge does not require osseointegration to function, so the device can be activated early. One disadvantage of Bonebridge is the sizable artifact on MRI created by the internal magnet. Studies of Bonebridge implantation demonstrate few complications, and hearing outcomes are audiologically equivalent to other bone conduction devices.
