⚕️Cochlear Implant Surgery: Step-by-Step Explanation



🩺A cochlear implant is a medical device that bypasses damaged portions of the ear and directly stimulates the auditory nerve, helping individuals with severe to profound hearing loss perceive sound.

Step-by-Step Surgical Procedure:

1. Pre-operative Evaluation

Hearing tests, imaging (CT/MRI), and medical assessments are done to determine eligibility.

Counseling is provided to explain the benefits, risks, and post-surgical expectations.



2. Anesthesia

General anesthesia is administered to ensure the patient remains unconscious and pain-free during the procedure.



3. Incision

A small incision is made behind the ear to expose the mastoid bone.



4. Mastoidectomy

The surgeon drills into the mastoid bone to access the middle ear and the cochlea.



5. Cochleostomy or Round Window Insertion

A small opening is created in the cochlea, or the electrode is inserted through the natural round window.



6. Electrode Insertion

The electrode array of the implant is gently inserted into the cochlea.



7. Implant Fixation

The internal receiver-stimulator is placed under the skin and anchored to the skull.



8. Wound Closure

The incision is closed with sutures and covered with a sterile dressing.



9. Post-Operative Care

The patient is monitored and discharged typically within 1–2 days.

Healing takes a few weeks before the external device is connected.



10. Activation and Rehabilitation



After healing, the external processor is fitted and programmed.

Auditory rehabilitation therapy begins to help interpret the sounds.


Note: Cochlear implant surgery is safe and highly effective, offering a chance to regain hearing and improve quality of life.
