Now, what is cochlear implant surgery? In cochlear implant surgery, the surgeon makes an incision behind the ear and opens the mastoid bone. The surgeon then looks for the facial nerves and creates an opening to reach the cochlea where the implant is inserted.

The implant is basically a small electronic device that electrically stimulates the cochlear nerves which are responsible for the hearing of a person. The implant is built in such a way that it picks up the sound with the help of a microphone and then it processes the sound and transmits it to the internal part of the ear from where the person perceives it and the internal part is placed under the skin to hear the sound.

Who requires cochlear implant surgery?

A cochlear implant is required to improve the hearing ability of a person or to restore it while helping the person to understand speech or any kind of sound. One should not confuse a cochlear implant with a hearing aid as both are different.

  • A hearing Aid just amplifies the sound louder but does not significantly improve the understanding of speech.
  • While a cochlear implant helps a person who struggles to understand speech with hearing aids, the implant significantly increases hearing in adults, old age, infants, and toddlers and helps them to learn to speak.

A cochlear implant helps individuals who are unable to process sound or

  • Who can hear from both the years but with lack of clarity.
  • Individuals who rely on lip reading despite wearing hearing aids.
  • Have difficulty in understanding while wearing hearing aids
  • Have hearing disability
  • Older people with poor hearing

Cochlear implant surgery is a procedure to implant a device that stimulates the auditory nerve, enabling individuals with severe hearing loss or deafness to hear sounds.
The cochlear implant device has electrodes that are placed in the inner ear. These electrodes stimulate the auditory nerve, bypassing damaged parts of the ear.
Candidates are individuals with profound hearing loss or deafness who do not benefit significantly from hearing aids.
Cochlear implants can significantly improve hearing, speech comprehension, and communication abilities for eligible candidates.
Risks include infection, damage to the facial nerve, device malfunction, changes in taste, and potential loss of residual hearing.
Cochlear implant surgery is generally safe, but like any surgery, it carries certain risks that should be discussed with a qualified healthcare professional.
Infection risk is possible but relatively low. Precautions are taken to minimize the risk of infection during and after the surgery.
There is a slight risk of damage to the facial nerve during surgery, but skilled surgeons take measures to minimize this risk.
Device malfunction is rare but can happen. Regular follow-up appointments and proper care can help prevent and address such issues.
While cochlear implants are designed to preserve residual hearing, there is a possibility of some changes in hearing sensitivity post-surgery.
