NYU Langone’s Cochlear Implant Center is one of the largest and most respected centers in the world. Our team of surgeons and audiologists has pioneered new technologies and techniques since the center opened in 1984. It offers specialized care for people who have been diagnosed with sensorineural hearing loss.
Our surgeons have successfully implanted cochlear devices in people from 4 months to 94 years of age. New research suggests that this surgery is safe for people of almost any age who are in good health.
A cochlear implant is a small electronic device that consists of an internal receiver that is surgically implanted just under the skin above the ear. The receiver connects to small devices that conduct electrical signals, called electrodes, that are implanted in the inner ear. An external device that contains a microphone, speech processor, and battery pack is worn above the skin behind the ear.
Cochlear implants work by completely bypassing the malfunctioning part of the ear. The external part of the device gathers and sorts sounds from the environment and converts them to electrical signals that are then transmitted to the internal receiver. The receiver sends these signals to electrodes in the inner ear. The electrodes then use these signals to stimulate the nerve pathway that connects the ear to the brain. The brain interprets information conveyed by the auditory nerve as speech or other sounds, allowing you to perceive sound.
Evaluation and Counseling
Before you decide to pursue surgery, doctors and counselors at the Cochlear Implant Center meet with you to ensure that you are a candidate for an implant. A good candidate is someone who has hearing loss caused by damage or dysfunction in the inner ear and whose hearing loss has not been improved by a hearing aid.
In addition, our doctors conduct imaging tests—for example, an MRI scan—to get a close look at the anatomy of your ear and confirm that a device can be implanted successfully. If doctors confirm that you are a candidate, the decision to proceed with surgery is a collaborative one.
NYU Langone’s expert team includes physicians, audiologists, counselors, and cochlear device experts who answer any questions you have about preoperative testing, the types of devices available, and surgery. In addition, an NYU Langone speech pathologist can perform a preoperative speech and language evaluation, and educators can provide comprehensive educational resources about what you can expect after surgery.
What to Expect During Surgery
The surgery to implant the cochlear device is frequently an outpatient procedure, which means no overnight stay at the hospital is required.
Doctors perform this procedure using general anesthesia. The surgeon makes an incision behind the ear, then creates a small opening in the bone behind the ear to access the inner ear and install a series of tiny electrodes. The electrodes connect to the internal component of the cochlear implant, called a receiver. The surgeon permanently installs the receiver under the skin above the ear. After the electrodes and receiver are in place, the incision is closed with stitches or staples.
What to Expect After Surgery
Recovery from surgery takes three or four weeks. During this time, skin and bone heal around the implanted device. Doctors schedule a follow-up visit 10 to 14 days after surgery to ensure everything is healing well.
Approximately four weeks after surgery, the external component of the cochlear implant—which contains a microphone, speech processor, and battery pack—is attached to the skull above the ear. Many people cover this component with their hair, making it less noticeable.
After all of the components of the device are in place, our cochlear implant care team activates the device and begin the process of adjusting the way it processes sound to optimize your ability to hear. During the following months, they meet with you regularly to ensure you are comfortable using the device and can adjust the settings as often as needed.
