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

While most noise is just in the background for us, loud noises, either in small spurts or prolonged exposure, can cause hearing loss. This has been happening more frequently as the levels of noise in an industrialized society go further up.

Noise induced hearing loss explained
Loud noises may damage the sensitive structure of your ear, which process the sound waves into information. They eventually become nonfunctional, resulting in a loss of hearing in that range. If exposure to loud noises continues, then this might extend to the entire range of hearing and may cause total hearing loss.

What may cause noise induced hearing loss?
Some of the scenarios which may cause noise induced hearing loss are as follows:
1. Listening to music on high volume: If you constantly listen to music or watch movies at your home on very loud levels, then it may result in noise induced hearing loss. In fact, listening to music or watching movies with headphones in your ears is one of the leading causes for hearing loss. Headphones have deceptively loud levels and may result in damaged hearing overtime.

2. Noise of household tools: Household tools such as drills, mixers, grinders, mowers, and saws can expose you to loud levels of noise. Even a quick exposure for a few seconds could temporarily damage your hearing. 

3. Occupational problems: Occupations such as construction, factory work and military that require the use of power tools on a constant basis can also cause hearing loss. The sound from the resulting friction might damage your hearing very quickly. Explosions and impacts are also causes of hearing loss in the military and law enforcement departments.

Prevention and treatment
Treatment: It is difficult to treat hearing loss as in most cases; it may be permanent, except sudden shocks, when your hearing might come back to normal. The only treatments for hearing loss are hearing aids or cochlear implants which can restore hearing partially.

Prevention: Prevention is the best method to avoid hearing loss and in most cases, you should wear ear protection such as mufflers or sound level reduction devices to protect your hearing. Also, practice listening to music, watching TV or movies at lower levels, especially if you are on the headphones. 

Induced Hearing Loss - Facts You Should Be Careful about It!

SSHL is not like any other normal hear-loss trouble. Rather it is quite a severe condition. Sudden deafness can occur at any time due to several reasons. This trouble does not affect both the ears rather only one specific ear is usually affected, and thus this is one of the prominent signs that can help the doctors to understand that SSHL has occurred. 


What are the leading causes of this hearing loss?

    Head injury: If you have faced any severe kind of head injury ever, then it might bring SSHL. This is why you are suggested to get necessary treatment on time so that this kind of hearing loss can be avoided.
    Loud-noise exposure: If your ears are exposed to louder noises or sounds in a consistent manner, then there is a greater possibility of the occurrence of this hearing loss. Thus, you should stay away from unwanted noises. 
    Ageing: With the increase in age, hearing power slowly decreases. However, if you take proper precautions from the very beginning, then SSHL can be definitely avoided. 
    Blood-circulation troubles: Interrupted blood-circulation creates different physical troubles out of which hearing loos is one of the most prominent one. And if timely treatment is not provided, then it might get converted into SSHL. 
    Ototoxic medication: This kind of medication should not be continued for long without doctor's prescription otherwise SSHL might occur. 
    Lyme disease: This is a kind of disease, which occurs due to tick bites and this is pretty infectious in nature. Apart from that, this disease is now considered as one of the main sources of SSHL. 

How to evaluate this hearing loss? 

    History analysis: The history of the patient needs to be known first otherwise SSHL cannot be perfectly treated. If the history shows that the patient already has an existing trouble of ear loss for which SSHL has been proven, then in accordance with the same the treatment can be prescribed. 
    Laboratory and imaging: Laboratory analysis is one of the main methods for evaluating SSHL and necessary images of the ears boost the potentiality and importance of this kind of analysis to a great extent. 
    Quick evaluation: This kind of medical evaluation is mainly made on the basis of the symptoms. The doctors often follow the signs thoroughly in order to determine as to whether the patients have SSHL or not. This evaluation is highly supported by different medical tests that are prescribed by the doctor.

Sudden Sensorineural Hearing Loss: Causes and Evaluation

Usher syndrome is a genetic disorder that is characterized by complications in vision and hearing; the most common of them being partial/complete loss of hearing and retinitis pigmentosa. Retinitis pigmentosa is characterized by progressive deterioration of the retina, resulting in deprivation of peripheral vision and subsequent night blindness.

The symptoms and its rate of progression usually vary among people. Usher syndrome is classified into three types:

Type 1: In this type, children are born with balance issues and hearing loss problems. The symptoms of night blindness and loss of peripheral vision associated with  Retinitis Pigmentosa  only appear in the early stages of adolescence.
Type 2: In type 2, children are born with moderate to mild hearing loss problems. Retinitis Pigmentosa develops soon after the child reaches adolescence.
Type 3: In type 3 Usher Syndrome, children are usually born with normal hearing skills, however, loss of hearing and Retinitis pigmentosa occur soon after puberty.
Causes
Hearing loss in Usher syndrome occurs when the nerve cells that are present in the cochlear (inner ear s spiral cavity) are affected by genetic mutation. A similar problem occurs in the cells of the retina leading to loss of vision. These cells allow conversion of light into electrical signals for the brain to interpret them. Both the parents need to pass the mutated gene to the child for it to be affected. If the child has only one gene, then he/she rarely develops the symptoms.

Treatment
This disorder does not have any prescribed course of treatments. The vision loss that occurs in this disorder can be slowed down by nutritional therapy. This therapy involves providing the body with essential amounts of vitamin A which can help in reducing vision loss.

Usher Syndrome - Things You Must Know!

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?

Here are 6 signs to watch out for that could indicate 'You need to get your Ears tested':

1. Your TV is blaring: Do you often find people around you shouting above the TV sound complaining that it's too loud? When you find it hard to hear the TV at the average volume and find yourself turning up the sound, this could signify a hearing loss. Doctors are seeing a growing number of patients visiting them after prolonged exposure to loud music and sounds.

2. You find it hard to hear phone conversations: Do you find yourself asking the person on the other end of the phone line to 'repeat' themselves, or find yourself pressing the phone instrument right into your ear? If you are trying so hard to hear, you might find yourself missing out on bits of the conversation as focussing to clearly hear the conversation is exhausting work. Getting a hearing test might be a good option if this sounds like you.

3. You have trouble hearing in noisy environments: When you are out dining with friends or family at a busy restaurant or accompanying a friend shopping in a busy street, all that background noise makes it difficult to hear what the people are saying. People with hearing loss often have problems masking out background noise.

4. Family members telling 'you're going deaf'?: Trust the views of the people closest to you, they never lie about your health. Family members often are the first to sense signs of hearing loss as they find themselves repeating things to you or calling out louder to get your 'attention'.

5. You find yourself staying away from social occasions, family gatherings or avoid being the first to start conversations

6. You find yourself leaning closer to people to follow the conversation or staring at their lips trying to lip-read what's being said.
