Cochlear Implant Tips

Cochlear Implant - Know More About It!

Cochlear Implant - Know More About It!

Cochlear Implant is an electronic device replaced with the inner ear (cochlea) of the patients who are unable to send sound waves to the brain.

The surgery is performed on the patients who have the problem of hearing loss due to the damaged hair cells in the inner ears. The implant helps the patient to hear which are not responding to other hearing aids.

Conditions for Cochlear Implant:

Cochlear implants help people to hear with clarity. They are not like hearing aids, which make the sound louder, but it helps send sound waves to the brain and replaces the damaged hair cells in the inner ear. Following are cases where it is beneficial:

  1. People who find it difficult to hear clearly with hearing aids.

  2. Those with moderate hearing loss in both ears.

  3. Patients with 50% or fewer score in the sentence recognition test.

  4. Patients with 60% or less score in sentence recognition test with hearing aids on.

It is suggested to opt for cochlear implants in both ears. The reason is to give the patient a better perspective of sound direction and clarity in understanding the words.

How does the Cochlear Implant work?

Cochlear Implant is an electronic device with an embedded sound processor that has to be worn outside ears or on the body. Following steps are involved in cochlear implant:

  1. The sound captured by the processor is converted digitally by the processor and sent to the coil inside the ears of the patient.

  2. The implant converts digitally coded sound waves to electrical impulses.

  3. The electric impulse stimulates the hearing nerve of the patient.

  4. Then sends these impulses to the brain.

Benefits of Cochlear Implants:

The cochlear implant is a blessing for people who have been suffering from hearing loss for a very long time. It provides aid to people who have not benefited from hearing devices. The benefits of the cochlear implant are:

  1. Hear better.

  2. Studies have shown that people with cochlear implants have better sentence recognition scores instead of hearing aids.

  3. The patient can concentrate better in the crowd and can hear conversations across the table.

  4. Reconnect with the missed sounds.

  5. Enjoy music on the phone.

Cochlear Implant improves the quality of life of people with hearing loss. It gives them an aid to understand and engage themselves in a conversation. However, it takes time to learn the interpretation of the sound signals that are received from cochlear implants. But, the patient can learn and lead a normal life with the implant. The factors which affect the benefits of Cochlear implants are:

  1. The extent of hearing loss

  2. The duration of the hearing loss and the condition before implantation

  3. Damage to inner hair cells

  4. Other health issues

  5. The practice and rehabilitation time have been done in practice after implantation

The cochlear implant is performed in the patients after taking extensive tests determining the condition of the patients. It is activated after 2-6 weeks of surgery to give the surgery site a time to heal. Most people are discharged from the hospital after surgery and are prepared for the use of an implant. There are training sessions and classes for patients who have just gone for cochlear implants.

Cochlear Implants - Knowing Their Utility!

Cochlear Implants - Knowing Their Utility!

Introduction:

A cochlear implant 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 specialized nerve cells in the hearing sense organ (cochlea). 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 implanthelps 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.

Cochlear Implant - Know Utility Of It!

Cochlear Implant - Know Utility Of It!

A cochlear implant is an electronic device that is used to restore hearing ability in people who suffer from hearing loss due to inner ear damage. Unlike hearing aids which amplify sounds so people with hearing loss are better able to perceive them, cochlear implants directly transmit electronic sound signals to the auditory nerve. They work by compensating for damaged cochlea, the part of the inner ear that converts sound waves into neural impulses which are perceived by the brain. 

  1. A child who cannot hear will also never be able to speak. 
  2. Inability to hear and speak puts a person at a disadvantage in society. 
  3. Simple tasks like talking on the phone which we take for granted become impossible. 
  4. Conventional methods of learning like attending a classroom lecture become impossible. 
  5. Brain development and intelligence is closely linked to the development of speech and language. 
  6. Inability of parents to communicate with the child leads to emotional distancing. 
  7. Integrating a hearing disabled person into society becomes a frustrating experience for all involved. 
  8. Cost of integration per capita is much higher when compared to the cost of Cochlear Implant. 
  9. Children with Cochlear Implants are fully integrated into society with normal hearing & speech. 
  10. Children with Cochlear Implants can attend regular schools & colleges 
  11. Early identification of hearing impairment gives children a better chance of developing speech and language skills, and of making the most of social and emotional interaction from an early age. 

Cochlear implants offer a multitude of benefits to people experiencing hearing loss, especially infants and children with severe hearing loss who are just starting to process language and speech. Some of these benefits are: 

  1. Hearing and communication – Cochlear implants improve hearing significantly, especially to a level where normal communication can be restored. It enhances the person’s ability to hear speech without relying on visual cues such as lip reading or hand signs. It makes telephonic conversation a lot easier. Cochlear implants also help people regulate their own voice and volume so that it is easier for others to understand them. 
  2. Quality of life - It can help people with hearing loss listen to and enjoy music and also watch television with sounds. It helps people listen to sounds in a noisy environment and differentiate soft sounds from loud ones. 
  3. Safety – Cochlear implants enhance the individual’s safety as it allows the person to be able to hear warning sounds like honking cars or ambulance sirens. This will allow people to navigate public spaces in a much safer way. 
  4. Society - For children with hearing loss, cochlear implants can help them adjust a lot better to regular schools instead of requiring special institutions. 
  5. Brain development - It can help infants with cochlear damage develop their speech recognition and speaking skills much faster. 

Cochlear implants 

  1. Only device of its kind that can restore a special sense.
  2. Consists of 2 parts-
    • One part is surgically implanted in the body 
    • Second part is worn behind the ear and communicates with internal part using wireless signals 
  3. Persons of any age can get a cochlear implant, from less than one-year-old children to 90-year-old persons have received implants all around the world. 
  4. Cochlear implants can be done for partial hearing loss also, know as Hybrid implant that preserves the residual natural hearing and augments hearing only in certain sound frequencies in which hearing loss is present. 
  5. Are being used for indications other than hearing loss also like Tinnitus
  6. Surgery is a daycare procedure for most patients. 

Consult a doctor to get a clear assessment of whether you would be an eligible candidate for a cochlear implant and what to expect from the procedure.

How Can Cochlear Implant Be Beneficial?

How Can Cochlear Implant Be Beneficial?

Cochlear implant is a medical device that provides direct electrical stimulation to the hearing nerve in the inner ear. Children and adults with severe hearing loss may 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 similar conditions as adults and in addition have support from their educational institutions to the development of auditory skills.

Cochlear Implant - Know Merits Of It!

Cochlear Implant - Know Merits Of It!

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 the 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

What Is The Difference Between A Cochlear Implant & Baha?

What Is The Difference Between A Cochlear Implant & Baha?

BAHA Implant
Bone Anchored Hearing Aid (BAHA) is a device surgically implanted to help people suffering from a loss of hearing. Most conventional hearing aids transmit sound through air conduction. The BAHA device is suitable for conductive or mild-moderate mixed hearing loss.

Problems with hearing in the middle or outer ears can be helped with the BAHA device. The sound waves received by the BAHA device bypass the middle ear and get delivered straight to the functioning cochlea in both ears.

A BAHA device comprises of two parts:

  1. The processor 
  2. A fixture which is surgically implanted behind the ear in the bone.

The implant is embedded in the bone. The processor, which remains outside, is attached to the implant. There is a microphone on the processor that picks up sounds. The sounds are passed on to the implant. The implant vibrates which triggers the Cochlear. You can consider wearing a BAHA implant if other conventional hearing aids do not work for you. BAHA implants are also given to people with collapsed or irritated ear canals.

Cochlear Implant Surgery

A complex, small electronic device that helps to hear in people with severe hearing loss or deafness is used in the Cochlear Implant Surgery. The cochlear implant comprises an external piece behind the ear and another piece that is surgically implanted under the skin. A cochlear implant comprises of four parts:

  1. A microphone which picks up sounds from the surroundings
  2. A speech processor which chooses and arranges the sounds the microphone picks up
  3. A receiver/stimulator and transmitter that picks up signals from the speech processor and changes them into electric impulses
  4. An electrode ray, a bunch of electrodes, receives impulses the stimulator sends and transmits them to different areas of the auditory nerves.

The implant does not cure deafness; it only gives you a useful portrayal of sounds in the environment and considerable aid in understanding speech.

The surgery is done in the following way:

  1. The area around the site of the implant is shaved or cleaned
  2. The patient's vital signs are monitored through cables, patches and monitors attached to him or her
  3. General anaesthesia is administered through IV or through a face mask
  4. After the device is implanted, the patient is taken to the recovery room for the anaesthesia effect to lessen.

Cochlear Implants - Know Its Advantages!

Cochlear Implants - Know Its Advantages!

A cochlear implant is beneficial if you are deaf or have difficulties in hearing. Cochlear 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 loss caused 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 infection, bleeding 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 - The Many Benefits Of It!

Cochlear Implants - The Many Benefits Of It!

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.
