The benefits depend on your procedure and rehabilitation process. With a cochlear implant, you might be able to:. Cochlear implant surgery is a generally safe procedure. However, it presents potential risks, such as:. For some individuals, it might not help at all. Before you leave the hospital, a healthcare professional will show you how to care for the incision.
The incision needs to heal before the implant is activated. About 1 month after surgery, your doctor will add the external parts.
The internal components will then be activated. This will help you improve your hearing and speech skills. It usually involves working with an audiologist or speech-language pathologist. This device, which is surgically implanted in your cochlea, converts sounds into electrical impulses, which are interpreted by your brain.
This is essential for improving your outlook and using the cochlear implant successfully. If you've lost your hearing, you have options to reverse your hearing loss. Although people have different reactions to hearing loss, for many it can….

Noise-induced hearing loss results from repeated loud noises that damage the delicate structures in your ear. Learn how it happens here. Ear infections can sometimes cause hearing loss due to inflammation and fluid buildup. Learn more about how long hearing loss typically lasts with an…. Conductive hearing loss is when a problem with the outer or middle ear makes it difficult to hear soft sounds.
We explain causes, diagnosis, and…. What is TruHearing? We review what to know if you're looking for hearing aids and hearing health services. There are many things to look out for when buying hearing aids.
Some people can learn to communicate on the telephone. Others can only recognize sound. Getting the maximum results can take up to several years, and you need to be motivated. Many people are enrolled in hearing and speech rehabilitation programs. Once you have healed, there are few restrictions.
Most activities are allowed. However, your provider may tell you to avoid contact sports to lessen the chance of injury to the implanted device. Cochlear implantation in adults.

Editorial team. One part of the device is surgically implanted into the bone surrounding the ear temporal bone. It is made up of a receiver-stimulator, which accepts, decodes, and then sends an electrical signal to the brain.
The second part of the cochlear implant is an outside device. This part of the implant receives the sound, converts the sound into an electrical signal, and sends it to the inside part of the cochlear implant. Although criteria are slightly different for adults and children, they are based on similar guidelines: The person should be completely or almost completely deaf in both ears, and get almost no improvement with hearing aids.
Anyone who can hear well enough with hearing aids is not a good candidate for cochlear implants. The person needs to be highly motivated. After the cochlear implant is placed, they must learn how to properly use the device.
The person needs to have reasonable expectations for what will occur after surgery. The device does not restore or create "normal" hearing. Taste disturbances --the nerve that gives taste sensation to the tongue also goes through the middle ear and might be injured during the surgery.
Numbness around the ear. Reparative granuloma --this is the result of localized inflammation that can occur if the body rejects the implant. There may be other unforeseen complications that could occur with long term implantation that we cannot now predict.
Sound impressions from an implant differ from normal hearing, according to people who could hear before they became deaf. At first, users describe the sound as "mechanical", "technical", or "synthetic".
This perception changes over time, and most users do not notice this artificial sound quality after a few weeks of cochlear implant use. May lose residual hearing. The implant may destroy any remaining hearing in the implanted ear. May have unknown and uncertain effects. The cochlear implant stimulates the nerves directly with electrical currents. Although this stimulation appears to be safe, the long term effect of these electrical currents on the nerves is unknown.
May not hear as well as others who have had successful outcomes with their implants. May not be able to understand language well. There is no test a person can take before surgery that will predict how well he or she will understand language after surgery. May have to have it removed temporarily or permanently if an infection develops after the implant surgery. However, this is a rare complication. May have their implant fail. In this situation, a person with an implant would need to have additional surgery to resolve this problem and would be exposed to the risks of surgery again.
May not be able to upgrade their implant when new external components become available. Implanted parts are usually compatible with improved external parts. That way, as advances in technology develop, one can upgrade his or her implant by changing only its external parts.
In some cases, though, this won't work and the implant will need changing. May not be able to have some medical examinations and treatments. These treatments include: MRI imaging. MRI is becoming a more routine diagnostic method for early detection of medical problems.
Even being close to an MRI imaging unit will be dangerous because it may dislodge the implant or demagnetize its internal magnet. FDA has approved some implants, however, for some types of MRI studies done under controlled conditions.
Will depend on batteries for hearing.
