Cochlear Implants

Also known as: cochlear implant surgery.

What are cochlear implants?

Cochlear implants are a form of hearing aid that are surgically implanted in the skin behind the ear. The implants also have an external portion that picks up sound and transmits it to the inner portion. They provide a sense of sound to people with extreme hearing problems or deafness.

What happens during the procedure? 

The surgeon makes an incision behind the ear and opens the mastoid bone. Then the electrodes and receivers are implanted before the incisions are closed.

Is any special preparation needed? 

A number of tests and hearing assessments are required to ensure that cochlear implants are the right choice for you and your specific hearing problems.  

What are the risk factors? 

Infection, bleeding, injury to surrounding organs and tissues, dizziness, nerve damage, dry mouth, numbness, tinnitus or ineffectiveness of the implants are all potential risk factors.
