If you have problem in hearing or you are deaf, cochlear implant surgery may help you get back the sounds you miss. It is a small electronic device that partially restores hearing. It is not like hearing aid which makes the sound louder. Cochlear is a small device a sound processor which doctor fits behind your ear through surgery. This device sends impulses directly to the auditory nerve which carries sounds to the brain. The processor captures sound signals and transmits them to a receiver implanted under the skin behind the ear. the receiver sends the signal to the snail-shaped inner ear. then the signal stimulates the auditory nerve which directs them to the brain.

The implant doesn’t make you sound normally. it usually helps you to hear sounds such as telephones, doorbells, and alarms. People who have profound hearing loss can understand the speech in person or over the telephone better than they did hear with hearing aid.

How to prepare

For Cochlear implantation, general anaesthesia will be given to you and you will be asleep during the procedure. before the surgery, the patient has to stop taking temporary medication and doctor will guide you about the eating and drinking time before the implant. The patient will get a thorough medical evaluation to determine a cochlear implant is a good option or not.

  • Tests of hearing, speech.
  • Physical examination to assess the health of the inner ear.
  • Another test like CT or MRI imaging of the skull to access the cochlear.
  • Psychological testing to determine your ability to learn to use cochlear implants. During the procedure, the surgeon will make a small incision behind your ear and a slight depression in the skull bone where the internal device rests. The surgeon will then create a small hole in the cochlea then the doctor will thread the electrode array of the internal device through this hole. The incision is stitched closed and the internal device is under the skin

After the procedure, you will get a discharge on the same day or next day. You need to visit a doctor after one week to remove the stitches. The cochlear implant device won’t turn on until two to six weeks after the surgery just to give you a set time to heal.
