Implants are designed only for individuals who attain almost no benefit from a hearing aid. They must be two years of age or older (unless childhood meningitis is responsible for deafness). Otolaryngologists (ear, nose, and throat specialists) perform implant surgery, though not all of them do this procedure. Your local doctor can refer you to an implant clinic for an evaluation. The evaluation will be done by an implant team (an otolaryngologist, audiologist, nurse, and others) that will give you a series of tests: Ear (otological) evaluation: The otolaryngologist examines the middle and inner ear to ensure that no active infection or other abnormality precludes the implant surgery. Hearing (audiological) evaluation: The audiologist performs an extensive hearing test to find out how much you can hear with and without a hearing aid. ? X-ray (radiographic) evaluation: Special X-rays are taken, usually computerized tomography (CT) or magnetic resonance imaging (MRI) scans, to evaluate your inner ear bone. ? Psychological evaluation: Some patients may need a psychological evaluation to learn if they can cope with the implant. ? Physical examination: Your otolaryngologist also gives a physical examination to identify any potential problems with the general anesthesia needed for the implant procedure.
