  1. Cochlear Implant Presentation Jennifer Callaway M.S. CCC-SLP Speech/Language Pathologist Grafton Elementary School John Long Middle School jcallaway@grafton.k12.wi.us

  2. 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

  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

  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

  5. 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

  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

  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.

  8. 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

  9. One Model: Nucleus Esprit 3G • Made by Cochlear • Easy-to-use controls and light weight - only 15 grams with batteries •  Batteries: 3 high power zinc-air batteries • Battery life varies •  Two programs for different listening environments •  Built-in telecoil for access to phones and theaters •  Wireless access to Microlink FM •  Whisper Setting™ to bring soft sounds closer

  10. What does a Cochlear Implant sound like? • http://www.utdallas.edu/~loizou/cimplants/ • Normal speech • Speech via Cochlear Implant (8 channel)
