Cochlear Implants - 6 Amazing Benefits You Must Know!

You should consider undertaking a cochlear implant in case you are experiencing hearing loss or are turning deaf. This is a small device that gets planted in your ear through a surgical procedure. It sends impulses to your auditory nerves directly, as a result of which sound signals get carried to your brain. Cochlear implants may not make you hear normally again, but help you with different sounds, and in the recognition of the different sounds around you like alarms, telephones, and door bells.

How it works?

  1. A cochlear implant is fit for children and adults who suffer from the sensorineural hearing loss. This condition damages the tiny hair cells in your inner ear, which is called the cochlea. Hearing becomes impaired when these get damaged.
  2. The device consists of two specific parts. The first part or the receiver-stimulator is placed under your skin via a surgical procedure. The other part of the device is the speech processor. It has to be worn around your neck in the form of a hearing aid.
  3. The external device is, however, larger in size than a usual hearing aid. The receiver gets placed under your skin, behind the ear via a small incision. It is connected to electrodes.
  4. This is inserted into the cochlea of your inner ear. The surgery requires a few hours to be undertaken successfully.
  5. The speech processor has to be placed two weeks after the surgery is undertaken. The processor can be connected to the microphone, and this can be worn around the ear.
  6. You can wear it on any other part of your body, based on your lifestyle and age.

Benefits of cochlear implant
The major benefits of a cochlear implant are as follows:

  1. You might be able to hear speech almost normally.
  2. You will be able to understand speech better, and will not have to depend on lip reading.
  3. It will be much easier and simpler for you to listen to the television and talk over the phone.
  4. You will be able to listen to music better.
  5. You may also be able to pick up various sounds around you that include soft, medium, and loud sounds.
  6. You will be able to control your own voice better. This makes other people understand you better.

If you are suffering from severe hearing loss, a cochlear implant may be able to change your life for the better. However, the results are not the same for all, and vary among people. It is possible for some people to benefit more from such an implant than others.

Cochlear Implants - All You Should Be Aware Of!

cochlear implant is beneficial if you are deaf or have difficulties in hearingCochlear implants are not hearing aids which just raise the volume of the different sounds you hear; they are surgically implanted inside your head. The implant transmits impulses straight to the auditory nerves which send the signals to the brain.

Cochlear implants can help you with sounds such as telephones, alarms or doorbells ringing. You can even understand speech or listen to music again with the help of cochlear implants.

How Cochlear Implants Work?

Cochlear implants are for adults and children with sensorineural (hearing losscaused by damage to the inner ear) hearing loss.

The device consists of two parts:

  • The receiver-stimulator: this part is surgically implanted under the skin.

  • The speech processor: this part is placed externally, behind the ear.

The receiver-stimulator is placed first, and two weeks after the procedure, the speech-processor is installed. If there are sounds around you, the microphone on the speech processor will pick them up and transform them into electrical impulses. The receiver-stimulator receives these impulses through the electrodes inside them. The electrodes then send the electrical impulses to stimulate the auditory nerves, and ultimately, the sounds picked up will reach the brain.

Advantages Of Cochlear Implants-

Some advantages of cochlear implants include:

  1. Being able to hear at normal volumes.

  2. Understanding speech without the need to lip-read.

  3. Listening to and talking over the phone get easier.

  4. Being able to hear music better after the surgery.

  5. Picking up loud, medium and soft sounds.

  6. Modulating your own voice gets better, so others understand you easily.

Disadvantages/Risks Associated With Cochlear Implants-

The risks of cochlear implants are common surgical after-effects such as infectionbleeding and anaesthetic side-effects. Some other complications include:

  1. Alteration in sense of taste due to nerve injury.

  2. Paralysis or weakness on the face due to nerve damage.

  3. Dizziness.

  4. Tinnitus (Ringing in the ear).

  5. Fluid leakage around the brain.

  6. Device can be faulty or get infected.

  7. Meningitis (An infection in the brain).

People Who Can Get Cochlear Implant-

You are eligible to get a cochlear implant if you have:

  1. Profound to severe hearing loss.

  2. Problems with the hearing aid.

  3. A strong wish to improve your hearing.

  4. Even children with severe hearing loss in both the ears can get a cochlear implant.

Cochlear Implants - How Are They Helpful?

Cochlear implant is a medical device that provides direct electrical stimulation to the hearing nerve in the inner ear. Children and adults with a severe hearing lossmay be helped with cochlear implants. A cochlear implant is a prosthetic substitute directly stimulating the cochlea and it does not cure deafness or hearing impairment.

A cochlear implant completely by-passes the normal hearing mechanism and stimulates the auditory nerve directly by means of an internally implanted electrode assembly. The implant consists of an external portion that located behind the ear and an interior portion which is surgically implanted under the skin. An implant has a microphone, a speech processor, a transmitter and an electrode array. The sound from the environment is picked by microphone and transmitter and receiver/stimulator sends them to speech processor to convert them into electric impulses.

The speech processor placed with the microphone behind the ear, or it is a small box-like unit worn in a chest pocket. The speech processor digitizes the sound signals and sends them to a transmitter just behind the ear. The electrode array collects the impulses from the stimulator and sends those to different regions of the auditory nerve. The electrodes stimulate the fibers of the auditory nerve, and sound sensations are perceived.

A cochlear implant is very different from a hearing aid. Hearing aids amplify sounds so that they can be detected by damaged ears. Cochlear implants bypass damaged portions of the ear and directly stimulate the auditory nerve. Hearing via a cochlear implant is different from normal hearing and takes time to adjust. However, it enables many people to understand other sounds in the environment, recognize warning signals, , and understand speech in person or over the telephone.

The benefits from a cochlear implant depend on many factors, such as the age of the patient when he or she receives the implant, the hearing loss present pre or post patient developed language skills and finally the motivation of the patient and family support.

Once a person is referred for cochlear implant, more testing is done which includes audio logic testing, psychological testing, medical examination, and tests performed by the surgeon. It is done to ensure that the candidate will benefit from a cochlear implant and will have the motivation to participate in the process. Once the decision is made to go ahead, the surgery is done. Sometimes it involves an overnight stay in the clinic, and sometimes it is done on an outpatient basis. Six weeks post-surgery, patient is fitted with the external microphone and speech processor and implant is activated and programmed.

The best candidates are those having severe hearing loss in both ears, limited benefit from hearing aids, medical condition that makes surgery risky. Children can be considered for cochlear implants if they have the similar conditions as adults and in addition have support from their educational institutions to development of auditory skills.

Cochlear Implant - How Can They Help You?

Traditionally, people resort to hearing aids in order to take care of their auditory problems. The perception of hearing reduces as age progresses and people find it absolutely necessary to come up with ways by which they can improve their hearing. However, cochlear implants have become extremely popular because of the method that it uses in comparison to the traditional methods of hearing aids.

What is a cochlear implant?

A cochlear implant is an electronic medical device that replaces the function of the damaged inner ear. Unlike hearing aids, which make sounds louder, cochlear implants bypass the damaged hair cells of the inner ear (cochlea) to provide sound signals to the brain.

Who can they help?

The cochlear implant technology can help people who:

  1. have moderate to profound hearing loss in both ears
  2. receive little or no benefit from hearing aids
  3. score 50% or less on sentence recognition tests done by hearing professionals in the ear to be implanted
  4. score 60% or less on sentence recognition tests done by hearing professionals in the non-implanted ear or in both ears with hearing aids.

Many people have cochlear devices in both ears (bilateral). Listening with two ears can improve your ability to identify the direction of sound and separate the sounds you want to hear from those you don’t.

What are the benefits of a cochlear implant?

Many adults with cochlear implants report that they:

  • Hear better with a cochlear implant than with a hearing aid
  • A previous study has shown that people with a cochlear implant achieve an average of 80% sentence understanding, compared with 10% sentence understanding for hearing aids1.
  • Can focus better when in noisy environments.
  • Find it easier to have conversations with people across meeting tables, in restaurants and other crowded places.
  • Reconnect with missed sounds that they could not hear before their cochlear implant.
  • Feel safer in the world as they can hear alarms, people calling out and approaching vehicles.
  • Talk and hear on the phone.
  • Enjoy music.

??How is a cochlear implant different from a hearing aid?

A cochlear implant is very different from a hearing aid and is appropriate for individuals for whom hearing aids fail to provide benefit. A hearing aid makes sounds louder. Sound still travels through all the portions of the ear (outer ear, middle ear, inner ear) to the hearing nerve. A cochlear implant bypasses these structures and directly stimulates the hearing nerve with electrical energy. Because hearing aids amplify sounds and rely on the hearing system to convey the message, people with severe to profound hearing loss may be able to hear, but not understand speech well. The main objective of a cochlear implant is to improve speech understanding in quiet. Clarity with a cochlear implant is usually better than a hearing aid because the implant does not make sounds louder but delivers them to the hearing nerve.

There are a number of symptoms, which people should be looking out for before concluding that they have a hearing disorder:

  1. Inability to hear properly
  2. Excessive ear pain and stress on the brain
  3. Failure to communicate properly
  4. Discomfort in the mouth or nose
  5. Other feelings of anxiety or stress that may actually be a consequence of the hearing loss problem

Know How Does A Cochlear Implant Works!

The inability to hear can be frustrating. Thankfully, children and adults with a severe hearing loss no longer have to rely on only sign language to communicate. Cochlear implants are hearing aids that can help treat loss of hearing. Unlike the other types of hearing aids available, cochlear implants do not amplify sounds but bypass the part of the ear that does not function properly and delivers sound to the auditory nerves in the form of electrical signals. In this way, it does not restore hearing or cure the loss of hearing but allows severely deaf people to hear sounds. Also, unlike other hearing aids, surgery is required to insert the cochlear implant.

Components of a Cochlear Implant
Cochlear implants can be worn by children and adults. They can be implanted in one ear or both ears at the same time. There are two components to a cochlear implant: the internal component and the external component.

  1. Internal component: There are two internal components of a cochlear implant. These must be surgically implanted under the patient’s skin. This surgery is usually performed while the patient is under general anaesthesia. It can typically take 2 to 4 hours and one night’s hospital stay may be needed after the surgery. The first is a receiver that is located under the skin of the temporal bone. This is accompanied by one or more electrode arrays.
  2. External component: Once the incision site has healed, the external components of the cochlear implant may be put in place. The external component of a cochlear implant can be further categorized into two units: the transmitter and the small hook-like part that wraps itself around the ear. This consists of the microphone and the speech processor. A small wire links the two units together. The transmitter is usually positioned over the internal part of the device.

How does a cochlear implant work?
The microphone behind the patient’s ear picks up sounds, amplifies them and transmits them to the speech processor. The processor then analyses the sounds and digitizes them. These signals are then forwarded to the transmitter which codes them and sends them to the internal receiver through magnetic coupling. The receiver converts the codes into electrical pulses and dispatches them to the electrodes. These electrodes are inserted seep into the inner ear. When they receive the signals, they stimulate the auditory nerve. These nerves then interpret the signals as sounds.

Know The Advantages Of Cochlear Implant!

Are you experiencing severe hearing loss or turning deaf? To get back your normal hearing, you should undertake a cochlear. It is a small device which is planted in your ear via a surgical procedure. It sends impulses to the auditory nerve directly and as a result, sound signals are carried to your brain. Such an implant does not make you hear like normal again, but it helps you with sounds and knowing sounds around you such as telephones, alarms and doorbells.

How Does Cochlear Implant Work?

Cochlear implant is meant for adults and children who have sensorineural hearing loss. This is a condition which damages the tiny hair cells in the inner ear known as the cochlea. Your hearing gets impaired when these are damaged. A cochlear implant sends signals to the auditory nerve directly by skipping the damaged hair cells.

The device has two distinct parts. One part is the receiver-stimulator which is placed under the skin via surgery. The other part is the speech processor, which is worn around the back of the ear like a hearing aid. The outside device is, however, bigger in size than a hearing aid.

The receiver is placed under the skin, behind the ear through a small incision and it gets connected to electrodes. This is put into the cochlea of the inner ear. The surgery takes about some hours to be completed.

Two weeks after the surgery, the speech processor is fitted by the doctor. You will have to wear a microphone behind your ear. The processor can be connected to the microphone and worn around the ear. It can also be worn at any other place of the body, depending on your age and lifestyle.

Advantages of Cochlear Implant-

The major advantages of a cochlear implant are as follows:

  1. You may be able to hear speech at an almost normal level.

  2. You may understand speech without the help of lip reading.

  3. It will be easy for you to talk on the phone and listen to the television.

  4. Your experience of listening to music will improve.

  5. You will be able to pick up different sounds starting from soft, medium to loud sounds.

  6. You can also control your own voice in a better way, which will make it easier for others to understand you.

A cochlear implant can be a life changing device if you suffer from serious hearing loss. The results are not the same for everyone and vary from person to person. Some people may benefit more than others.

Cochlear Implants - How Can They Help?

Introduction

A cochlear is one of the best electronic medical devices in the modern world. A cochlear implantation is a surgical implantation done on a person who is deaf. This device provides a sense of hearing. It does not amplify the sound like normal hearing aids. It stimulates the auditory nerve directly.It has many advantages and is currently more useful than your average hearing aid.

How can Cochlear implants help?

One may get to hear speech at a normal level. In adults, the result is immediate while in children the rate at which they improve is very slow. In adults, there is a rapid improvement for about three months after which the improvement is slow. Most people can perceive a wide range of sounds varying from soft, medium to loud like the slamming of a door, the barking of dogs, and the ringing telephone. Makes a person more secure and self-reliant. It is very important for a person to be able to hear in case of critical conditions like the fire alarm. Cochlear implant helps with these. One can actually hear auditory voices, even though they are robotic. A person with cochlear implant does not need to lip read.Children can think about studying in mainstream schools instead of studying in a specialized school for deaf people.

Now we will discuss some details about the drawbacks. And, it is not a foolproof method and doesn't guarantee that hearing a person may lose the residue hearing that they have. There are several drawbacks to a cochlear implant.

Let us discuss some down below:

A surgical process involves a lot of money and it has a lot of ordeals associated with it. Therefore, before getting a cochlear implant done ask your specialist to elaborate if it will be of any help to your condition. The cost of maintenance is also very high. It will be difficult for people who are not inborn deaf to cope up with hearing conditions as the sounds are distorted and background noises interfere with the process of hearing. Irritation of your skin, muscle spasms, and even facial paralysis are some of the side effects of this implant. But these are rare conditions. Sounds are translated by the device first and may sound unnatural. It takes time and proper training before a person can be at ease with this condition. In case you have a concern or query you can always consult an expert & get answers to your questions!
