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:

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

Those with moderate hearing loss in both ears.

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

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:

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

The implant converts digitally coded sound waves to electrical impulses.

The electric impulse simulates the hearing nerve of the patient.

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:

Hear better.

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

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

Reconnect with the missed sounds.

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:

The extent of hearing loss

The duration of the hearing loss and the condition before implantation

Damage to inner hair cells

Other health issues

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 Implant - How Do They Help?

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 inner ear that converts sound waves into neural impulses which are perceived by the brain. 

A child who cannot hear will also never be able to speak. 
Inability to hear and speak puts a person at disadvantage in society. 
Simple tasks like talking on the phone which we take for granted become impossible. 
Conventional methods of learning like attending a classroom lecture become impossible. 
Brain development and intelligence is closely linked to development of speech and language. 
Inability of parents to communicate with child leads to emotional distancing. 
Integrating a hearing disabled person in to society becomes a frustrating experience for all involved. 
Cost of integration per capita in much higher when compared to cost of Cochlear Implant. 
Children with Cochlear Implants are fully integrated in society with normal hearing & speech. 
Children with Cochlear Implants can attend regular schools & colleges 
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: 

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. 
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. 
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. 
Society - For children with hearing loss, cochlear implants can help them adjust a lot better to regular schools instead of requiring special institutions. 
Brain development - It can help infants with cochlear damage develop their speech recognition and speaking skills much faster. 
Cochlear implants 

Only device of its kind that can restore a special sense.
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 
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. 
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. 
Are being used for indications other than hearing loss also like Tinnitus. 
Surgery is a day care 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.

Cochlear Implant - The Many Benefits Of It

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:
a) The processor 
b) 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 hearing in people with severe hearing loss or deafness is used in the Cochlear Implant Surgery. The cochlear implant comprises of 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:
i. The area around the site of the implant is shaved or cleaned
ii. The patient's vital signs are monitored through cables, patches and monitors attached to him or her
iii. General anaesthesia is administered through IV or through a face mask
iv. After the device is implanted, the patient is taken to the recovery room for the anaesthesia effect to lessen.

BAHA Implant and Cochlear Implant Surgery

Hearing is one of the five senses that you or anyone else relies on for communication and a whole host of other things. Among the five senses, touch, smell, taste, hearing and sight, it is often hearing, which is the most easily affected. You don't have to be a senior citizen to experience hearing loss as it is quite common among younger people as well. This problem is also getting widespread with each passing day.

Before coping with hearing loss, the first job is to detect it
If you have a hunch that you or any of your loved ones is suffering from hearing loss, it is important that you get it diagnosed. Some of the common symptoms of hearing loss will be:

 Hearing difficulties while talking to someone over the phone
 Straining to hear conversations with family members or friends in household situations 
 People usually need to repeat what they talk to you with a louder voice
 You often hear complaints that you keep the tv too loud.
 In crowded situations, such as family gatherings or a restaurant, you have problems listening to people.

Although this condition tends to affect senior citizens, an increasing trend shows younger people i. E. People mostly in their 40 and 50s and even younger than that suffer from this condition.

How to deal with hearing loss?
Some of the options to deal with hearing loss are mentioned below.

 Once diagnosed with hearing problems, change your ways of communication: if you or your loved ones have been diagnosed with hearing problems, it is important that both adjust your ways to deal with the problem. Rather than getting angry at the other for not being able to communicate effectively, develop and strategize ways to make communication less problematic and erratic.
 Cochlear implants: this is a newer technology, which has gained popularity in the past decade or so. These are directly implanted into the inner ear and are designed to bypass the damaged areas of the ear and directly stimulate the auditory nerve. These have become very popular, although, are not a replacement of natural hearing. It is only prescribed for people who have severe hearing loss or are deaf.
 Hearing aids: although selecting a hearing aid is difficult as the patient needs to be comfortable, once selected it is one of the best solutions for the hearing impaired. The functionality of these devices can be extended with the hearing assistive technology or hat devices that can focus the audio waves depending on the situations and give a more tailored approach for every individual's needs.

Dealing With Hearing Loss

Hearing loss is a common sensory problem that generally develops with increasing age or due to prolonged or persistent exposure to loud noises. It is one of the most typical problems that occurs throughout the world. If you are suffering from partial hearing loss, you may find ways of keeping in touch with your family and friends. If you are not suffering from such the following may help you keep your hearing intact for years to come.

Types of hearing loss
There are two main types of hearing loss: 
1. Conductive hearing loss where the problem lies in the middle ear, eardrum or ossicles. A conductive hearing loss affects the passage of sound between the eardrum and the inner ear. Sound passes down the ear canal to the ear drum and through the middle ear, where the sound is transmitted across the middle ear by the three bones called the ossicles to the inner ear.

Causes of conductive hearing loss:
1. Malformation of outer ear, ear canal, or middle ear structures
2. Fluid in the middle ear from colds
3. Ear infection (otitis media - an infection of the middle ear in which an accumulation of fluid may interfere with the movement of the eardrum and ossicles
4. Allergies
5. Poor eustachian tube function
6. Perforated eardrum
7. Benign tumors
8. Impacted earwax
9. Infection in the ear canal
10. Foreign body in the ear
11. Otosclerosis

2. Sensorineural hearing loss where there is damage in the inner ear, cochlea or hearing nerve. Sensorineural hearing loss (snhl) occurs when there is damage to the inner ear (cochlea), or to the nerve pathways from the inner ear to the brain. Most of the time, snhl cannot be medically or surgically corrected. This is the most common type of permanent hearing loss.

Causes of sensorineural hearing loss:
1. Exposure to loud noise
2. Head trauma
3. Virus or disease
4. Autoimmune inner ear disease
5. Hearing loss that runs in the family
6. Aging (presbycusis)
7. Malformation of the inner ear
8. Meniere's disease
9. Otosclerosis 
10. Tumors

Coping with hearing loss
Antibiotics and eardrops are often prescribed to treat hearing loss and its symptoms. In many cases, people suffering from severe hearing loss use hearing aids. Hearing aids are tiny instruments that people use in their ears to make sounds louder. People who suffer from hearing loss cope with their problems through increased concentration and focus. The usual way involves reading the moving lips of the person while they talk. Prevention is better than cure and is the best solution to avoid long term hearing loss. Avoiding continuous loud noises, to the possible extent helps prevent hearing loss to a great extent.
