Cochlear Implants: Understanding the Benefits and Risks

4. Before Surgery

Eligibility is usually determined by an otolaryngologist, a doctor who specialized in the ears, nose, and throat. Physical examination of the ears rules out any physical abnormalities or infections. The doctor may then test hearing aids to ensure this isn't a viable alternative for the patient and perform hearing tests. MRI and CT scans help the surgeon determine which ear to implant. The patient must also undergo a psychological evaluation prior to surgery; coping with an implant can be challenging.
