What is a Bone Conducting Hearing Implant?
A Bone Conducting Hearing Implant is the only implanted hearing treatment 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.
It comes in 3 parts:
The Implant: is a tiny titanium screw implanted into the skull, it provides an anchor for the abutment and the sound processor.
An Abutment: is attached to the implant into which the sound processor will then attach.
The Sound Processor: acts as middle ear, converting the sound waves into vibrations, passed through the implant to the bone and from there to the working inner ears.
There are three suppliers of Bone Conducting Hearing Implants in the UK:
Conventional Bone Conducting Hearing Implants consist of a titanium implant, an external abutment and a detachable sound processor:
Another type of Bone Conducting Hearing Implant consists of an internal implanted magnet, an external magnetic spacer and a sound processor.

Bone Conducting Hearing Implants can also be worn on a softband. This allows for young children to get the benefit of a system, without having the surgery. The softband can also be used to test the sound of a Bone Conducting Hearing Implants before proceeding with the surgery.

Who Is Suitable for a Bone Conducting Hearing Implant?
Conductive Hearing Loss
A conductive hearing loss means that sound cannot travel freely through the ear canal and middle ear to the cochlea. This type of hearing loss can be caused by an abnormality in the structure or blockage (excess ear wax / middle ear fluid) of the outer ear, ear canal or middle ear.
Mixed Hearing Loss
A mixed hearing loss means that there is both a conductive and senorineural hearing loss (SNHL). A SNHL is hearing loss is a result of damage to the hair cells within the cochlea and/or the hearing nerve. SNHL occurs naturally as part of the aging process, but there are other causes as well.
Single Sided Deafness (SSD)
A Single Sided Deafness (SSD) means that there is no sufficient hearing function of one cochlea.
For more information on the types of hearing loss, see the Action on Hearing Loss website.
How do I get a Bone Conducting Hearing Implant?
There are many local Audiology Services which provide Bone Conducting Hearing Implant. To be considered for a System you have to have a Bone Conducting Hearing Implant assessment to see if you are a suitable candidate. We recommend that you discuss your hearing needs with your Audiologist.
