Cochlear implants are composed of two main parts: an external processor and an internal implant.

External processor:

An external processor is a device worn outside the body that captures sound and sends it to the internal implant. It typically consists of a microphone, speech processor, and transmitter that attaches to a magnet on the head.

The external processor can be easily removed for activities like showering or sleeping.

Internal implant:

An internal implant is a device surgically implanted in the inner ear that directly stimulates the auditory nerve to produce sound. It typically consists of an electrode array that is inserted into the cochlea and a receiver that is implanted under the skin behind the ear.

The internal implant is not visible from the outside and requires a surgical procedure for implantation.

Overall, the external processor and internal implant work together as a system. The external processor captures sound and sends it to the internal implant, which directly stimulates the auditory nerve to produce sound that the brain can perceive.

Cochlear implants are most commonly used for individuals who are severely hard of hearing or deaf in one or both ears and who have not benefited from hearing aids.

Candidates for cochlear implants must undergo a thorough evaluation by an audiologist and an otolaryngologist to determine if they are suitable candidates. The evaluation includes hearing tests, medical exams, and imaging studies to assess the structure of the inner ear.

The evaluation will also consider the individual’s age, overall health, and communication needs.

Evaluation: You will undergo a thorough evaluation by an audiologist and an otolaryngologist to determine if you are a suitable candidate for a cochlear implant.

Pre-operative preparation: You may need to undergo medical tests and imaging studies to prepare for the surgery. You may also need to stop taking certain medications and avoid eating or drinking before the surgery.

Anesthesia: You will be given general anesthesia to ensure you are comfortable and pain-free during the procedure.

Surgery: The surgeon will make a small incision behind your ear and insert the implant into your cochlea. The electrode array is then carefully inserted into the cochlea, and the incision is closed.

Recovery: You will need to allow some time (2 – 3 weeks) for the incision to heal before the device can be activated. You may need to stay in the clinic overnight.

Activation: Once the incision has healed, you will return to the audiologist for programming and activation of the device.

Rehabilitation: You will need to undergo a significant rehabilitation process to learn how to interpret the new sounds. This typically involves working with a speech therapist and an audiologist to gradually adjust to the new sounds and learn how to distinguish between different sounds.

Cochlear implants are a remarkable technology that has revolutionized the way individuals with hearing loss can communicate with the world. While the procedure is not without risks, it has proven to be a safe and effective treatment for severe hearing loss. If you or a loved one is experiencing significant hearing loss, it is worth considering an implantable hearing aid like cochlear implant.
