What is a bone-conduction hearing implant?

A bone-conduction hearing implant (BCHI) is a surgically implanted hearing device that works through direct bone conduction, working independently of the ear canal and middle ear.

It has been well recognised as a hearing treatment for conductive and mixed hearing loss since 1977, and was approved for single-sided deafness (SSD) in 2002.

Conventional BCHIs consist of a titanium implant, an external abutment and a detachable sound processor.

Another type of BCHI consists of an internal implanted magnet, an external magnetic spacer and a sound processor.

The BCHI can help people with chronic ear infections, malformed ear canals, otosclerosis and single–sided sensory hearing loss who cannot benefit from conventional hearing aids.
