Part 2, Presentation 1
The cochlear implant (CI) is a prosthetic replacement for the inner ear (cochlea) and is only appropriate for people who receive minimal or no benefit from a conventional hearing aid.
The cochlear implant bypasses damaged parts of the inner ear and electronically stimulates the nerve of hearing. Part of the device is surgically implanted in the skull behind the ear and tiny wires are inserted into the cochlea.
- beginning studies of electrical stimulation on humans
- active research of electrical stimulation in human ears
- first wearable implants designed for long-term stimulation
- commercial development of the cochlear implant device began
- United States Food & Drug Administration (FDA) granted the first approval for implantation in adults
- FDA granted approval for cochlear implants in children
- cochlear implantation is a safe and effective medical procedure for individuals who are severely to profoundly deaf with minimal benefits from conventional hearing aids
Candidates for implants are adults or children (two years or older) with all of the following:
* weekly adjustments of the MAP and communication therapy for the first month.
