The implant consists of an external portion that sits behind the ear and a second portion that is surgically placed under the skin.
An implant consists of:
- A microphone, which picks up sound from the environment.
- A speech processor, which selects and arranges sounds picked up by the microphone.
- A transmitter and receiver/stimulator, which receive signals from the speech processor and convert them into electric impulses.
- An electrode array, which is a group of electrodes that collects the impulses from the stimulator and sends them to different regions of the auditory nerve.
Both children and adults who are deaf or severely hard-of-hearing can be candidates for implants. According to the Food and Drug Administration (FDA), more than 324,200 people worldwide have received implants till date.
You need an implant if you:
- Have moderate to profound hearing loss in both ears
- Receive little or no benefit from hearing aids
- Score 50% or less on sentence recognition tests done by hearing professionals in the ear to be implanted
- Score 60% or less on sentence recognition tests done by hearing professionals in the non-implanted ear or in both ears with hearing aids.
The surgical procedure for cochlear implants starts with a careful evaluation by ENT surgeon, anesthetist, audiologist and physician. A little incision in made at the back of the ear and then the surgeon implants the receiver. The receiver is then connected to electrodes that are surgically inserted inside the cochlea. The surgery usually takes 1-2 hours to complete.
