The cochlear implant surgery in Varanasi is an electronic device that is developed to help people with inner ear damage. It is placed in the cavity of the ear and replaces the functions of the inner ear. People who are suffering from a hearing loss can benefit from this technology as it acts to pacify the adverse effects of hair loss in the ear cavity and allow sound to be efficiently transferred to the hearing nerve which further carries it to the brain. It can be used in one ear or bilaterally (in both ears). Experts recommend bilateral implants as they enhance the sound hearing experience and allow the listener to make a judgment about the direction of the sound, as well as selective listening.
