What is a Cochlear Implant? A small, complex electronic device Provides a sense of sound to a person who is profoundly deaf or severely hard of hearing Implant is surgically placed under the skin behind the ear An implant has four basic parts: Microphone Speech processor Transmitter and receiver/stimulator Electrodes
Slide 3-

Structures of the Ear and the Cochlear Implant Normal Ear Middle ear: Tympanic membrane Ossicular chain (Malleus, Incus, Stapes) Inner ear: Cochlea Vestibular Nerve Cochlear Implant Receiver-stimulator portion of implant is surgically placed beneath the skin Small opening made into the cochlea and implant electrode is threaded in
Slide 4-

Who receives Cochlear Implants? Both children and adults can be candidates for implants. Approximately 59,000 people worldwide have received implants. (According to the Food and Drug Administration 2002 data) In the United States: 13,000 adults have cochlear implants 10,000 children have received them What is the cost? About $30,000 to $55,000

The Surgical Procedure Performed under general anesthesia Operation takes approximately three hours Patients generally able to go home the same day of surgery Patient not able to hear automatically ‘Hook Up’ Procedure occurs about 1 month post-implant Takes some time for the brain to get used to the stimulation from the implant Involves a rehabilitation program
Slide 6-

Cochlear Implants vs. Hearing Aids A cochlear implant is very different from a hearing aid. Hearing aids amplify sound. Cochlear implants compensate for damaged or non-working parts of the inner ear. Enable people to detect very soft speech and environmental sounds Hearing through an implant may sound different from normal hearing Types of Hearing Aids
Slide 7-

What a Cochlear Implant Can NOT do: An implant does NOT restore or create normal hearing. It cannot replicate the same sensitivity or speech understanding in all acoustic environments as a normal hearing person. Rather, it can give useful auditory understanding of the environment and help the individual to understand speech.

Limitations and Special Considerations Physical Activities: External portion must be removed during swimming Voice does not carry well in large outdoor spaces Poor acoustics in gyms Sound bounces off walls Background noise competes with speaker’s voice
