The sound processor is programmed to the individual needs of the recipient by an audiologist. A waiting period is required after surgery and prior to device activation to allow adequate healing of the incision site. Extensive shaving of the hair is not required. Surgery is often completed on an outpatient basis, with only a small incision hidden behind the ear. A CT scan and/or MRI is also needed to evaluate the physical structures of the inner ear where the electrodes will be placed.Ĭochlear implant surgery is performed by a Neurotologist or Otolaryngologist with specialty training in disorders of the ear. Testing for candidacy includes a comprehensive hearing test and speech recognition tests administered while wearing appropriate hearing aids. We provide comprehensive testing performed by audiologists and speech-language pathologists to evaluate candidacy for cochlear implantation. No other medical issues that would prevent surgery.Motivation to participate in aural training to support rehabilitation with implant.Motivation and willingness to learn to use the implant.Evidence of a functioning auditory nerve.Lack of acceptable benefit from hearing aids.Significant hearing loss in one or both ears.A surgical procedure is needed to place the internal portion of the device. Unlike most hearing aids, cochlear implants have both internal (surgically implanted in the ear) and external (worn outside the body) components. While hearing aids and other assistive listening devices simply amplify sounds, a cochlear implant transforms speech and other sounds into electrical energy that is used to stimulate surviving auditory nerve fibers in the inner ear. We provide several types of FDA- approved cochlear implants, depending on the patient’s need. An implant system consists of an external speech processor and an internal, surgically implanted electrode array. These electrical pulses are sent to the brain and interpreted as sound. Our experienced team of surgeons, audiologists, and speech-language pathologists guide patients and families through the cochlear implant process.Ī cochlear implant is an electronic device that stimulates residual nerve fibers in the inner ear. We have restored hearing to more than 3500 children and adults. The University of Michigan Health Cochlear Implant Program was established in 1984 and is one of the oldest and largest programs in the country. A cochlear implant can restore useful hearing and provide improved communication abilities for individuals with significant hearing loss.
