Cochlear implant in India is a very rare curative procedure then. Under the leadership of Dr. P.G.Visvanathan, Dr.Aruna Viswanathan and Dr.Anjana Visvanathan, we offered this technology to India, thereby making the cure for hearing loss accessible and affordable. The cochlear implant surgery is a very handy treatment for those who suffer from severe hearing loss or deficiency. Here, an electronic device (a receiver-stimulator) is implanted inside the ear of the patient. The implantation of this type is specially created electronic chip takes place in the rear portion of the temporal bone, which is known as the ‘mastoid bone’. This instrument will receive the sound codes through an outside mechanism comprising of a transmitter, receiver, and a processor. Then it decodes the same and gives the required notifications to the brain.
