Cochlear Implant Surgery in Nehru Enclave, Delhi

A cochlear implant is a small, medical and electronic device that is inserted under the skin of the ear to improve hearing. It also increases the ability to interpret speech. People with hearing loss and trouble understanding speech are the ideal candidates for the implant. 

Cochlear implant surgery involves putting a processor that captures sound from the environment. A receiver is inserted under the skin behind your ear. This receives the signals and sends it to the electrodes inserted in the cochlea. This in turn signals the auditory nerve that is connected to the brain which interprets the signals. 

To know more, you can consult an ENT specialist near you or visit an ENT hospital in New Delhi.

What is cochlear implant surgery?

A cochlear implant is an electronic device inserted under the skin of the ear to improve hearing and the ability to interpret speech. What makes cochlear implants different from hearing aids is that cochlear implants convert electronic impulses to signals for the brain. A hearing aid's purpose is to amplify sounds and make them louder. 

Before the surgery is performed, a patient will have to go through a battery of tests. These include a hearing test and a speech test along with a physical exam of your inner ear. A CT scan or MRI is conducted to assess the state of the cochlea and the inner ear. 

On the day of your surgery, a doctor will administer general anesthesia before conducting the surgery. The surgeon will cut a hole behind your ear, indent and open your mastoid bone. This allows him to insert the electrodes into your cochlea. The next step involves putting a receiver under the skin behind your ear. The doctor will close your incision and move you to the recovery room. You will be under observation for a few hours after which you will be discharged.

After the surgery, you will be given instructions on how to change your stitches and dressing. You will be required to go for follow-up appointments every few days. Four to six weeks after your surgery, your doctor will put in the external part of the implant and activate its internal part.

Your doctor will also recommend that you visit a speech therapist after your surgery for rehabilitation.
