You also may receive counseling to make sure you understand the large follow-up commitment required after the implant surgery, as well as what to expect regarding device performance and limitations. After that step, the next step is usually implantation surgery, which is done under general anesthesia. It typically takes between two and four hours and most people spend one night in the hospital. The person will not be able to hear yet. Although the internal components have been placed, the surgical site must heal before the external device is placed.
About four to six weeks after the surgery, the patient will return to the cochlear implantation center to be fitted with the external device. At this appointment, the audiologist will activate the cochlear implant and begin the process of mapping the processor for the individual's specific needs.
When the cochlear implant is "turned on," this is the first time many children and adults are experiencing sound. Whether first hearing a spouse's voice, their own voice, a parent's voice or the audiologist, it's quite an emotional and memorable milestone for the patient or parent. This first appointment will be followed by other fine-tuning and adjustments to the cochlear implant map as the patient begins his or her new hearing journey.
Many people need several follow-up visits over a few months to adjust the mapping of the signals to the electrodes, as well as to help the person become accustomed to his or her device.
Especially for those who've never heard sound before, an auditory training program is necessary to help the brain learn how to process the new auditory stimulation. Much like hearing aids, people will want to schedule regular visits with their audiologist for occasional adjustments and hearing tests. In many cases, cochlear implants are covered by Medicare or Medicaid and many private and commercial insurers. Coverage can vary widely, and patients may still be responsible for significant out-of-pocket costs.
Most surgeons who perform cochlear implants have dedicated insurance experts on staff who can help patients understand and navigate individual plans and answer questions.
Cochlear implants may require a prior authorization in order for insurance to pick up the tab. Cochlear implants are covered under the statutory Medicare benefit provision for prosthetic devices.
Medicare has a longstanding policy of providing coverage for cochlear implants when the patient meets the coverage criteria and without regard to whether the implant is unilateral or bilateral one ear or both ears. Medicare reimbursement rules, however, are complex and can change.
As with any surgical procedure involving an implanted medical device, there are risks. According to the FDA, they include:.
In the U. Your ENT doctor and audiologist will recommend the best cochlear implant for you, based on your hearing exam results and anatomical considerations. Cochlear now makes a hybrid design , which only stimulates the cochlea in the high frequencies for people who have high-frequency hearing loss. These devices work best for people with severe-to-profound hearing loss at high frequencies, yet who still have some residual, lower-frequency hearing abilities.
The first hybrid cochlear implant was approved by the FDA in March If you are interested in learning more about whether you might be a good candidate for cochlear implantation, talk to an ENT physician or audiologist for a referral to a cochlear implant center.

What is a cochlear implant? This woman is wearing an off-the-ear cochlear implant known as the Kanso 2. It's made by the Cochlear company. As cochlear implant technology has improved and become better understood, clinicians realized that offering an implant earlier resulted in better outcomes.
When a patient has profound hearing loss before the procedure, the nerve has gone through a deprivation period before being re-stimulated with the implant. Earlier implantation reduces or eliminates that deprivation period and leads to a better outcome for the patient.
Although cochlear implants are used across the lifespan, people tend to only associate them with infants and older adults. While these patient populations have success with implants, working-age adults often get overlooked as candidates. Another finding from the internal study was that referring providers may have mistakenly equated a referral for implant evaluation with a recommendation to actually get the procedure done.
However, a referral just means that a patient will be assessed for how well their hearing aids help them listen. To alleviate these concerns, the Cleveland Clinic Hearing Implant Program has taken steps to clarify which types of patients make the best referral candidates and to remind clinicians that a referral is just the first step in the evaluation process.
But for those who do, the results can be life-changing, and the patient may end up actually trusting their referring provider more to make the right recommendations in their future visits. She notes that Cleveland Clinic is seeing an uptick in patients who are referring themselves because of increased awareness of the device. Sydlowski believes the process of how patients are identified as candidates must also be revised. A cochlear implant uses a sound processor that you wear behind your ear.
A transmitter sends sound signals to a receiver and stimulator implanted under the skin, which stimulate the auditory nerve with electrodes that have been threaded into the cochlea. Some types of cochlear implants have one external unit that has a speech processor, microphone and transmitter combined lower left , while others have these as separate external parts upper left and on right. A cochlear implant is an electronic device that partially restores hearing.
It can be an option for people who have severe hearing loss from inner-ear damage who are no longer helped by using hearing aids. Unlike hearing aids, which amplify sound, a cochlear implant bypasses damaged portions of the ear to deliver sound signals to the hearing auditory nerve.
Cochlear implants use a sound processor that fits behind the ear. The processor captures sound signals and sends them to a receiver implanted under the skin behind the ear.
The receiver sends the signals to electrodes implanted in the snail-shaped inner ear cochlea. The signals stimulate the auditory nerve, which then directs them to the brain.
The brain interprets those signals as sounds, though these sounds won't be just like normal hearing. It takes time and training to learn to interpret the signals received from a cochlear implant.
Within a year of use, most people with cochlear implants make considerable gains in understanding speech. Vivien Williams: The happy sounds of childhood, a brother's giggle, a mother's loving coo or the joy of your own calls of contentment.
Melinda Little: When you first hear it, you kind of say, "That's not true,' or, 'What can we do to help it? Vivien Williams: Aida's mom and dad, Melinda and Matt Little, took her to Mayo Clinic, where a team of experts diagnosed Aida with a rare genetic condition.
Vivien Williams: Geneticist Dr. Lisa Schimmenti says Waardenburg syndrome is a collection of symptoms caused by a change in a gene. Schimmenti: If you went and Googled this disorder, you'll see pictures of people who may have a white streak of hair, or they may have one blue eye and one brown eye…well, this the fish lab.
Vivien Williams: Some of the tools Dr. Schimmenti uses to learn about deafness similar to Aida's are tanks full of zebra fish. Schimmenti: We share 70 percent of our genome with zebrafish, and the same genes that cause conditions in us, cause the same condition in fish. Vivien Williams: But, unlike these fish, Aida may benefit from technology to help her hear. Matthew Carlson, M. Carlson: There's a lot of different changes that happen in the inner ear that result in this hearing loss, but the end result is loss of inner ear hair cells for almost all these different conditions.
Vivien Williams: Here are the basics on how hearing works. The outer ear collects sound, which travels down the ear canal to the ear drum. The soundwaves cause the ear drum and middle ear bones to vibrate. The sound waves then move into the inner ear, or cochlea, where tiny hair cells turn them into electrical signals that are transmitted to the brain.
A cochlear implant bypasses the missing hair cells. Baby Aida, like all patients who get cochlear implants, went through two steps.
First was surgery. Through a small incision, Dr. Carlson and his team Carlson: …slip a small group of electrodes or wires that are all kind of bundled together, and they follow the natural curvature of the cochlea. And the electrodes are connected to a device that's underneath the skin in the scalp. Vivien Williams: The device sends a tiny current via the electrodes to the cochlea and then to the brain. Matt Little Vivien Williams: Cochlear implants work for most people who have them, but there's always the chance they won't.
Aida's brother, parents, grandparents and cousins were all there the day audiologists at Mayo Clinic attached the outside piece behind Aida's ear and turned it on for the first time. Vivien Williams: To people in that room, witnessing Aida hear for the first time was to witness a miracle.
Matt Little: Just to be able to hear, — hear the sounds around her — that's what I'm looking forward to. Vivien Williams: For Aida to be able to hear the happy sounds of childhood. Vivien Williams: If hearing aids don't work for you, cochlear implants might. New technology is helping to make cochlear implants even better.
