How does a bone conduction or middle ear implant work?
Bone conduction and middle ear implants convert sound vibrations into mechanical vibrations that are transmitted to the inner ear. A small titanium implant is placed behind the ear or on one of the middle‑ear bones. An external sound processor captures sound and sends the signal via an inductive link to the internal implant. The implant then delivers mechanical vibrations through the bone to the cochlea, allowing sound to be heard.
Who is suitable for a bone conduction or middle ear implant?
Individuals may be suitable for a bone conduction or middle ear implant if they have:
What is the difference between a cochlear implant (CI) and a bone conduction (BCI) or middle ear implant?
The most suitable implant depends on the nature of your hearing loss. Cochlear implants are generally recommended for individuals with severe to profound hearing loss caused by damage within the cochlea. In contrast, bone conduction and middle ear implants are designed for mild to severe hearing loss where there is minimal damage in the cochlear but sound transmission through the external or middle ear is affected.
These implant types transmit sound through vibrations delivered to the cochlea, making them appropriate for people who cannot use traditional hearing aids for medical reasons. Bone conduction implants may also be beneficial for single‑sided deafness, improving sound awareness from both sides.
What is involved for candidacy assessment?
Before determining suitability for a bone conduction or middle ear implant, our clinical team conducts a structured assessment to ensure the best outcome for each patient.
How is a bone conduction or middle ear implant managed?
Management is provided by a specialised team of Ear, Nose and Throat surgeons and audiologists. Ongoing care includes:
Most recipients become confident using their device within 1–2 months, with annual follow‑up appointments after the first year.
