Cochlear Implant Surgery in India
A cochlear implant is a boon for patient having hearing loss. It is best and most effective in cases with paediatric patients. However the surgery can be performed in adults as well. Cochlear Implant surgery in India is mostly done on patients with hearing loss due to inner ear damage. It is different from the hearing aid as it does not amplify the sound. Rather it bypasses the damaged portion of the inner ear to send signal to the auditory nerves.
Cochlear Implant Working
Cochlear implants use a sound processor that fits behind the ear. The processor captures sound signals and sends them to a receiver implanted under the skin behind the ear. The receiver sends the signals to electrodes implanted in the snail-shaped inner ear (cochlea). The signals stimulate the auditory nerve, which then directs them to the brain. The brain interprets those signals as sounds, though these sounds won’t be just like normal hearing.
Surgery and Training
Cochlear implant surgery is performed by ENT Surgeons in India. It is done under general anaesthesia and lasts for about 1.5 hours. Before the surgery patient undergoes an MRI scan of the inner ear and brain as well as CT scan of the temporal bone. Apart from the radiological scans patient also undergoes hearing tests like audiometery. This is the part of planning for the cochlear implant surgery in India.
Cochlear implant can be placed in one ear or both the ears. However most of the ENT surgeons in India prefer to operate one ear at a time and see the results before operating upon the other. Patient needs to be in the hospital for one day. Post surgery the device is not activated for atleast 6 weeks. This is the time needed for healing post surgery. The activation of the implant in India is done by a team of ENT surgeon and audiologist who would adjust the sound processor to the comfort of the patient and check other components of the implant.
Rehabilitation After Surgery in India
Post activation a 6 weeks training is provided by the team of speech therapists, this is called rehabilitation. Rehabilitation involves training your brain to understand sounds heard through the cochlear implant. Speech and everyday environmental noises will sound different from what you remember. Your brain needs time to recognize what these sounds mean.
