Cochlear Implant

A cochlear implant is an electronic device that electronically stimulates the hearing nerve. It enhances hearing when hearing aids do not offer the level of sound clarity required to understand speech and spoken language.

A cochlear Implant is a life-changing option for those who are unable to hear effectively with hearing aids, due to severe hearing loss brought on by inner ear damage.

How does Cochlear Implant Work?

A cochlear implant bypasses damaged areas of the ear to send sound impulses to the hearing (auditory) nerve, as opposed to hearing aids which only amplify sound.

A Cochlear Implant has two parts- External & Internal

The External portion is located behind the ear. It has a microphone that is used to capture sounds. After processing the sound, it sends it to the implant inside.

During an outpatient procedure, the internal component is positioned behind the skin behind the ear. The cochlea, a component of the inner ear, is reached by a thin wire and a few tiny electrodes. The cochlear nerve receives impulses from the wire and relays them to the brain, where the sound data is processed to create a hearing sensation.

Although normal hearing is not restored, with the right therapy and practice, the improved hearing experience can lead to greater communication through easier lip reading and listening as well as heightened awareness of sounds in the surroundings. An individual with hearing loss may be able to hear and understand speech again or with improved clarity with the aid of a cochlear implant.

A hearing aid is not the same as a cochlear implant. Although a hearing aid increases sound volume, it may not greatly enhance speech comprehension.

A cochlear implant should be taken into consideration when a person finds it difficult to understand speech despite wearing hearing aids. The cochlear implant can greatly improve hearing in adults when the system is tuned properly and the patient is dedicated to rehabilitation therapy. Infants and toddlers with cochlear implants may benefit from listening and language development.

Cochlear Implant Surgery & Therapy in Children

A cochlear implant should be taken into consideration if the development of spoken language is a priority for the family of a young kid with considerable hearing loss.

The care given following the procedure and a long-term commitment from the patient and family to acclimate to the new way of hearing with a cochlear implant are both crucial to a successful cochlear implant surgery. Highly skilled specialists with a focus on hearing and spoken language should deliver weekly auditory rehabilitation. This is crucial in directing rehabilitation toward the intended outcome. This is especially true for young children, who must catch up in their speaking and listening abilities development.

With a cochlear implant, a child’s spoken and listening language development is influenced by a number of factors, including:

• Age at the time of the procedure (younger is better)
• Past surgical experience with hearing and language
• A home environment rich in languages and consistent rehabilitative therapy

The family should look for a qualified group that provides a thorough surgical, audiological, and rehabilitation programme that works in conjunction with the family’s preferred educational alternatives and institution.

Who is a Good Candidate for Cochlear Implant?

If you have hearing loss and still rely extensively on lipreading, you, your healthcare provider, and an audiologist might think about getting a cochlear implant.

Children under the age of one year who have severe hearing loss in both ears may be candidates for cochlear implants. Cochlear implants may also be given to older kids who have severe hearing loss.

In general, the following people are candidates for cochlear implant surgery:

• Those who have hearing loss and when hearing aids do not help
• Those who have low hearing clarity in both ears
• Those who miss half or more of spoken words, even when wearing hearing aids, without lip reading
• Those who strongly rely on lip reading even while using hearing aids,

A partially implanted cochlear implant is used to preserve hearing in cases of more moderate hearing loss such that a hearing aid and the cochlear implant can be worn in the same ear simultaneously.

To completely benefit from electrical hearing, however, a fully placed cochlear implant is required in situations with more severe hearing loss.

Everybody benefits differently from cochlear implants. Four to six weeks following surgery, or when the cochlear implant is turned on, the majority of people see a noticeable improvement in their awareness of sounds. The majority of people see the biggest improvements within the first six months. Speech understanding develops more gradually. Each person experiences this improvement to varying degrees. Auditory, or hearing, therapy following surgery can help with improvements in speech comprehension.

How is Cochlear Implant Surgery Done?

You would be advised to undergo a series of investigations- audiology tests, blood tests, CT, MRI, ECG etc to determine if you would benefit from a cochlear implant and if you are a good candidate for the surgery.

The surgery is done in a hospital setting under general anesthesia and takes anywhere between 2-4 hours.

What is the Recovery after Cochlear Implant Surgery Like?

You will receive instructions on how to take care of the incisions before leaving the hospital. Additionally, you’ll learn how to take care of your stitches and change dressings. After a day or two, you can wash your ears as usual. To check the incisions and remove the stitches, a follow-up visit is scheduled for either at activation or around a week later.

After the initial operation, you will need some time to recover before the implant device is turned on or activated. The external components of the cochlear implant will be added four to six weeks after the operation.

The inside gadget is then programmed and turned on, which prompts it to stimulate the auditory nerve in reaction to sounds.

The fundamentals of utilizing and maintaining the implant will also be covered. For modifications, you might need to come back multiple times over a few days. Over the course of several months, more adjusting will be done. The process of becoming familiar with a cochlear implant is slow. Visits with audiologists and speech-language pathologists will probably be necessary. With dedication, a cochlear implant can help you live a better quality of life.

What Results can I Expect from Cochlear Implant Surgery?

Cochlear implants have a great success record as medical prostheses. Only 0.2% of recipients reject them, making it a highly successful and acceptable procedure.

Adults gain right away from implant insertion. After the initial tuning sessions, the sound quality keeps getting better for around three months. The children will have to undergo longer rehabilitation to get the best from cochlear implant surgery.

Following a successful procedure and recovery, a person might be able to:

• Perceive various sounds, such as footsteps, a door shutting, or the ringing of a phone
• Reduced need to lip-read when understanding speech
• Recognize voices on the telephone
• Viewing television without closed captions
• Play music

However, it is important to note that cochlear implant surgery results vary from patient to patient. The age at which hearing was lost and the interval between hearing loss and cochlear implant surgery are variables that can impact the success of the procedure.

If a child is born with a profound hearing loss, obtaining a cochlear implant at an early age usually yields the best results.

The best outcomes for adults are typically linked to a shorter time of profound hearing loss prior to cochlear implantation. Although both types of adults generally do better following cochlear implantation, those with little to no familiarity with sound seem to benefit less from them.

Predicted results include:

Improved Hearing: When utilizing the device, many people who meet the requirements for cochlear implantation may gradually experience improved hearing.

Improved Tinnitus: Tinnitus, or ear noise, is not the main reason for receiving a cochlear implant, but while being used, the cochlear implant may partially suppress or lessen the severity of tinnitus.
