Frequently Asked Questions
What is a Cochlear Implant Surgery?
Cochlear Implant surgery is a medical procedure in which a small, complex electronic device is placed under the skin behind the ear. This electronic device [Cochlear implant] helps in stimulating the auditory nerves and allows the patient to hear. This is used to bypass the function of the cochlea that transforms the sound vibrations into signals and forwards these signals to the hearing nerve [auditory nerve]. This nerve will send those signals to the brain where they are translated to recognizable sounds. The Cochlear Implant consists of :
- Implant package
- Sound and speech processor
Sound and speech processor acts like a minicomputer that processes the sound into digital information and sends this information to the implant package in the form of electrical signals. Implant package is surgically placed inside the skull that helps in stimulating the auditory nerve by the electrical signals received from the sound and speech processor.
What are the advantages of a Cochlear Implant Surgery?
Advantages of the Cochlear Implant Surgery are:
- It treats sensorineural hearing loss.
- It helps patients to hear sounds who are not able to hear due to internal ear damage [Cochlear damage].
- It can improve the communication of the patient.
- Improves the quality of life of the patient.
- It helps in the recognition of normal and everyday environmental sounds.
- A patient can hear speech without visual cues.
What are the indications of a Cochlear Implant Surgery?

- The doctor may recommend a few tests such as an audiogram.
- The doctor may examine your ears for the presence of any active infections.
- The doctor will examine the external, middle, and inner ear.

What are the steps involved in a Cochlear Implant Surgery?
The following are the steps involved in the Cochlear Implant Surgery:
- General anesthesia will be given to sedate you.
- As soon as you are sedated, intravenous fluids may be given and monitor all the vital signs such as blood pressure, heartbeat, and respiratory rates, etc.
- Later, the area of the scalp where the implant needed to be placed will be shaved or clean.
- Then the surgeon will make an incision behind the ear.
- A slight depression in the skull bone [mastoid bone] is made.
- A few inches away from the ear, a small hole is drilled on the skull where the internal part of the implant is placed.
- Next, the electrode array is inserted into the round window and gently passes into the cochlea.
- Now, the incisions made are closed and the external component of the cochlear implant can be worn after healing of the incisions.
What is the postprocedure care/recovery care for a Cochlear Implant Surgery?
- You may feel well enough to go home on the same day of the surgery.
- After the surgery, you may feel pressure, pain or discomfort over the implanted ear.
- Sometimes you may feel nausea and dizziness.
- You may need to return to the hospital after a week to remove the stitches.
- The cochlear implant will be activated once the surgery site is healed well.
- Training to the brain may be given to understand the sounds through the implant. This is done in rehabilitation.
