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.
The Queen Elizabeth Hospital Audiology Centre has achieved national accreditation with the United Kingdom Accreditation Service (UKAS). Accreditation number: IQIPS 7978.
