What is a Cochlear Implant?

A cochlear implant is a small electronic medical device that improves moderate to severe hearing loss. It’s used to help hearing loss in adults, children, and babies.

This type of device is very different from a hearing aid, which serves only to amplify sound. A cochlear implant transforms sounds into electrical signals and transmits these signals directly to the auditory nerve of the inner ear, bypassing any damaged structures in the ear that are impeding normal hearing.



Parts of a Cochlear Implant​​​​​

All cochlear implants, regardless of manufacturer, consist of two general components:

. Internal device: The internal portion of the implant consists of two parts: the receiver/stimulator and the intracochlear electrode array.

. External hardware: The external portion consists of three parts: a microphone, a speech processor, and a transmitting coil.

How a Cochlear Implant Works

. Sound is picked up by the microphone, where it is sent down a cord to the speech processor.

. The speech processor filters the incoming acoustic signal into separate frequency bands, and then converts this information into digital form.

. The digitized signal is sent back up the cord to the transmitting coil, which is held in place by a magnet.

. The coil transmits the digitized information across the skin to the internal receiver/stimulator.

. The internal receiver/stimulator decodes the incoming signal and sends information in each frequency band to a different electrode within the cochlea. (The internal receiver/stimulator also contains a magnet to which the external coil sticks.)

. High-frequency information is sent to electrodes in the basal end of the cochlea, and low-frequency information is sent to electrodes in the apical end of the cochlea.

. Electrical stimulation from the intracochlear electrodes takes the place of damaged cochlear structures or hai​r cell - nerve synapses.

. The auditory nerve picks up the electrical signals from the electrodes and relays that information to the brain where it is interpreted as sound.

Why it's done

Cochlear implants can restore hearing in people with severe hearing loss who are no longer helped by using hearing aids. Cochlear implants can improve their communication and quality of life.

Cochlear implants may be placed in one ear (unilateral) or both ears (bilateral). Cochlear implants in both ears have started to be used more often to treat bilateral severe hearing loss — particularly for infants and children who are learning to speak and process language.

Adults and children who are as young as six to 12 months old can benefit from cochlear implants. People who have cochlear implants report improved:

. Ability to hear speech without needing visual cues such as reading lips

. Recognition of normal, everyday environmental sounds

. Ability to listen in a noisy environment

. Ability to find where sounds are coming from

. Ability to hear television programs, music and telephone conversations


10 common questions about cochlear implant meaning

1How long do cochlear implants last?
For the majority of patients, the sound quality will continually improve over the first six to twelve months. The cochlear implant is a lifelong commitment.
2Who qualifies for cochlear implants?
Adult candidates are generally eligible for an implant if they: Have severe or profound hearing loss in both ears. Get little or no benefit from hearing aids. Have no medical problems that could put them at risk during surgery
3What are the 3 main parts of a cochlear implant?
Parts of a Cochlear Implant​​​​​ Internal device (e): The internal portion of the implant consists of two parts: the receiver/stimulator and the intracochlear electrode array. External hardware (a-d): The external portion consists of three parts: a microphone, a speech processor, and a transmitting coil
4Why do people get a cochlear implant?
A deaf person does not have a functioning inner ear. A cochlear implant tries to replace the function of the inner ear by turning sound into electrical energy. This energy can then be used to stimulate the cochlear nerve (the nerve for hearing), sending "sound" signals to the brain
5How do you know if you need a cochlear implant?
If you have severe or profound hearing loss, a team of experts at a cochlear implant center can help you decide if the device and surgery will work for you. ... A hearing aid evaluation. CT or MRI scans to check the inner ear and hearing nerve. These tests will tell your doctor if your cochlea has a normal shape.
6What is the success rate of a cochlear implant?
A 10-year retrospective analysis of 57 patients showed that the CI malfunctioned in just 4 cases (7 percent). Other studies have found similar results. If implant failure has the highest rate at less than 10 percent of all surgeries, you can assume that your chances for a successful cochlear implant are pretty high
7Can adults get cochlear implants?
Cochlear Implants for Adults. For adults with moderate-to-profound hearing loss, cochlear implants can make a significant difference in their quality of life. ... Hearing aids amplify sounds so they may be detected by the ears. Cochlear implants bypass damaged portions of the ear and directly stimulate the auditory nerve
8Can you swim with a cochlear implant?
The cochlear implants can be fully submerged They are able to be completely submerged under water. ... Having cochlear implants that are waterproof will be so beneficial when he starts swimming lessons because he will be able to hear his instructor without having to rely on lip reading and sign
9How effective are cochlear implants?
Traditional hearing aids may improve hearing function by amplifying sound, but are often ineffective in people with severe (between 70-94 decibels [dB]) to profound (≥ 95 dB) sensorineural hearing loss. ... Cochlear implantation is not a treatment option for people with conductive or central deafness
10Can you hear normally with a cochlear implant?
The implant doesn't make you hear normally again, but it can help you with sounds. Most people with severe to profound hearing loss can understand speech in person or over the phone better than they did with a hearing aid. It can usually help you know sounds around you, including telephones, doorbells, and alarms.
