Cochlear Implants
A cochlear implant is an implantable hearing device for those for whom a hearing aid either no longer offers benefit or for those whose hearing is too poor to ever benefit from hearing aids.
This includes new born babies born deaf and children or adults who have lost enough hearing to qualify. There is no upper age limit.
Patients are assessed by a multidisciplinary team of audiologists, radiologists, surgeons and other relevant medical professionals. Should surgery be recommended, this is usually covered by most medical aid patients. Private patients can receive one through the state healthcare system.
The surgery involves placing the implant electronics package under the skin, against the skull and an electrode array is inserted into the inner ear (cochlea).
This is usually done as a day case procedure.
Once the incision has healed, the external “hearing aid” component connects over the internal implant with a magnet and the implant is switched on.
Patients can use the implant for hearing immediately, but will require a period of training to gain full value for the improved hearing.
Some patients benefit from an implant on each ear.
What is a cochlear implant?
It is a device used for hearing, when hearing aids cannot offer sufficient benefit.
How does a cochlear implant work?
An electrode array is placed into the cochlea (inner ear) in a surgical procedure. An external device picks up sound and sends a signal to the cochlear electrode array, which stimulates the correct nerve endings, thus sending a signal to the auditory part of the brain.
Who can get a cochlear implant?
Babies born deaf or anyone whose hearing has deteriorated to such a degree that a hearing aid can no longer provide benefit.
Candidates are assessed by a multi -disciplinary team to decide if they would benefit.
