Cochlear implant surgery is a medical procedure designed to restore hearing for individuals with severe to profound hearing loss. During the surgery, a small electronic device called a cochlear implant is implanted under the skin behind the ear. It works by directly stimulating the auditory nerve, bypassing damaged or non-functional parts of the inner ear. Following the surgery, recipients undergo a rehabilitation process to adapt to the new sensory input and improve their ability to understand speech and environmental sounds. Cochlear implant surgery has revolutionised the lives of many, offering a remarkable opportunity to reconnect with the world of sound and communication.
