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?

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.

All About Hearing Loss

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

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

Did you know your earphones are making you deaf? Here's how.

Fact: Roughly 1.1 billion people worldwide within the age group of 12-35 have been found to be at an increased risk of developing hearing problems.

Listening to loud music on handheld devices using earphones has become a common trend among youngsters these days. You might find it very relaxing to plug in your earphones and escape into your own world of music, but you need to know that this can cause serious damage to your ears. The worst part: you won't realise your ears are being damaged until it's too late.

So, exactly how is loud music damaging your ears?

Continuous exposure to loud music from earphones or other sources results in a medical condition known as Noise-Induced Hearing Loss (NIHL), which can be associated with irreversible damage to the ears resulting in deafness.

When you hear loud music for a considerable amount of time every day it affects your hair cells (nerve cells responsible for sending sound signals to the brain) negatively, so that their ability to respond to sound decreases. If this keeps on happening for many months, eventually the hair cells are damaged beyond repair. These cells cannot be regenerated, making you permanently deaf.

How loud is too loud?

If your ears are exposed to sounds at 95, 100, 105, 110 and 115 dB (decibel, the unit used for measuring sound) for 4 hours, 2 hours, 1 hour, 30 minutes and 15 minutes each day respectively, your ears are at risk of getting severely damaged. Also, playing music at 120 dB or above can damage your ears instantly. You can have a realistic idea about the relation between decibels and sounds you commonly hear by referring to this list:

30 dB: soft whisper
75 dB: busy traffic
90 dB: noise of a motorcycle at 25 feet
100 dB: noise of a farm tractor
140 dB: jet plane taking off
Moreover, if you experience the following symptoms regularly, there's a high chance that you need to get your ears treated soon:

A ringing sound in your ears when you are at a quiet place, which vanishes after a few minutes
You need to raise the volume of TV or music to the fullest to hear it properly
You have difficulty in hearing people talking at a distance of just 3 feet
Tips For Safer Listening

Use earplugs: The louder the noise and the longer you're exposed to it, the greater the chance of damaging your hearing. Protect your ears with ear protectors   earplugs or earmuffs   and get away from the noise as quickly or as often as you can. 
Turn down the music: Don't listen to your personal music player at very high volumes and never to drown out background noise. If the music is uncomfortable for you to listen to, or you can t hear external sounds when you ve got your headphones on, then it's too loud. It's also too loud if the person next to you can hear the music from your headphones.
Use the 60:60 rule: To enjoy music from your MP3 player safely, listen to your music at 60% of the maximum volume for no more than 60 minutes a day. 
Wear headphones: When listening to your personal music player, choose noise-cancelling headphones, or go retro with older muff-type headphones. Ear-bud style headphones and in-the-ear headphones are less effective at drowning out background noise. 
Turn down the dial: Turn down the volume on your TV, radio or hi-fi a notch. Even a small reduction in volume can make a big difference to the risk of damage to your hearing. 
Use earplugs when you re listening to live music: They can reduce average sound levels by between 15 and 35 decibels. They re widely available at many live music venues and shouldn t spoil your enjoyment of the music.
Don't put up with work noise: If you re experiencing noise at work, talk to your human resources (HR) department or your manager and ask for advice on reducing the noise and getting hearing protection.
Wear ear protectors: Wear ear protectors (earplugs or earmuffs) if you are using noisy equipment such as power drills, saws, sanders or lawn mowers.
Be careful in the car: Listening to music in a confined space increases the risk of hearing damage. Don t listen to music too loud for too long.
Have a hearing detox: Give your ears time to recover after they ve been exposed to loud noise. According to Action on Hearing Loss, you need at least 16 hours of rest for your ears to recover after spending around two hours in 100dB sound, for example in a club. Reducing this recovery time increases the risk of permanent deafness.

Your Headphones Can Turn You Deaf!! 

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?

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.
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.
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.
This is inserted into the cochlea of your inner ear. The surgery requires a few hours to be undertaken successfully.
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.
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:

You might be able to hear speech almost normally.
You will be able to understand speech better, and will not have to depend on lip reading.
It will be much easier and simpler for you to listen to the television and talk over the phone.
You will be able to listen to music better.
You may also be able to pick up various sounds around you that include soft, medium, and loud sounds.
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.
