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

What Causes Meniere s Disease?
Meniere's Disease is a disorder that basically affects the sense of balance and hearing of the patient. This condition takes place in the inner ear and it may cause problems like vertigo, where patients experience a spinning sensation and a ringing sound as well. This is a chronic disorder, which requires a number of lifestyle changes so that it can be managed and treated without becoming a debilitating problem.

Read on to know more about the symptoms and causes of the condition.

Symptoms: The various signs and symptoms of this disease include a feeling of fullness in the ear, which has been affected by the condition. Also, most patients have a spinning sensation and a ringing sound in the affected ear. Nausea and vomiting may also be caused by this condition, along with sweating and loss of balance. It is also normal to feel uncoordinated when you are suffering from this condition.

Secondary Symptoms: This condition may also cause many other complications, which are known as secondary symptoms. These include anxiety, depression and stress. This usually happens due to the problems in the ear and even the problem of vertigo. This may cause problems for people who climb heights or ladders for their work or even for other recreational causes. The constant sense of dizziness and spinning may cause a person to become anxious and undertake stress when it comes to carrying out various kinds of functions in day to day living.

Causes:  There are various causes of this condition, even though many medical reports suggest that the exact cause has not really been understood so far. As any doctor will tell you, the in the inner ear there is a labyrinth which contains fluids. When there is a problem with the composition and level of these fluids, the patient may develop Meniere s Disease. This condition specifically affects the inner part of the ear. This part is made up of passages and a cavity as well as soft membrane like structures with hair like sensors. These sensors respond to the fluid s movement within the ear. When this fluid does not have the appropriate levels, it can lead to many complications like Meniere s Disease, which affect the nerve impulse that these sensors catch and transmit to the brain.
Stages: This disease progresses over a set of three stages. In the very first stage, the patient will experience much dizziness and nausea, before that progresses to the second stage. In this stage, the patient will have moderate to severe vertigo. This is also known as the middle stage. Finally, this may culminate into the third or late stage, which leads to more frequent episodes of vertigo. The hearing of the patient and the ringing sound in the ears will also get worse in this stage.

Meniere s Disease -  What are the Reasons Behind It 

The sense of hearing is a complex one. The ears are divided into three parts: the outer ear, the middle ear and the inner ear. While the outer ear sends the sound to the middle of the ear, the middle ear sends the same to the inner ear through the conductor. The inner ear in turn sends the auditory signal to the brain where the signal is processed and gives rise to a sense of hearing. 

Problems in hearings can arise if there is a problem in any of these parts. However, more often than not it is the middle or inner ear that is affected. However, there may also be situations when there are problems in both the middle and the inner ear. In that case, it is known as a mixed hearing loss. 

What is Mixed Hearing? 

Loss If there is damage to the middle ear, it may precipitate a conductive hearing loss. Now, in addition to that, if there is a sensorineural problem, then it gives rise to mixed hearing. So, in the case of a mixed hearing loss, all the parts of the ear and even the brain may be involved. There may be damage to the outer ear, middle ear, inner ear, as well as the auditory nerve. 

Causes of Hearing Loss 

Since mixed hearing loss may result from damage to any part of the ear, it is necessary that the causes be grouped into different categories. 

  Sensorineural Hearing Loss 

Sensorineural loss may result from drugs, different illnesses, head trauma, malformation of the inner ear etc. Genetic predisposition may also precipitate such problems. 

  Conductive Hearing Loss 

Such type of hearing loss may result from excessive deposition of earwax, ear infections, perforation in eardrums, malformation of the middle or outer ear, as well as problems with the fluid in the middle ear. 

Symptoms of Hearing Loss 

Reduced hearing in either or both ears is considered to be delineating symptoms of mixed hearing loss. 

Treatment 

Since mixed hearing loss can result from sensorineural failure as well as damage to outer or middle ear, treatment needs to be divided into different groups too.   To treat Conductive Hearing Loss, doctors can use surgical or medical options. 

  For sensorineural hearing loss, doctors usually prescribe hearing aids. This indicates that treatment for mixed hearing loss may include treatment for conductive hearing loss as well as that for sensorineural hearing loss. So, it is usually a combination of both medical and surgical options. Physicians may prescribe both medicines and hearing aids or resort to surgical interventions and also prescribe hearing aids. Sometimes, physicians use special hearing aids or implants to treat mixed hearing loss. 

Conclusion 

In case a person is sensing reduced hearing in one or both ears, he/she needs to seek medical advice. It may be a symptom of mixed hearing loss. Getting in touch with an experienced physician is the first step towards that.

Mixed Hearing Loss - How To Treat 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

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. 

Cochlear Implants - 6 Benefits You Must Know!

What causes hearing loss? + How to ensure you can help it as you age

The partial or total inability to hear is known as hearing impairment or hearing loss. It can be present at birth, or develop later in life.

There are a number of factors, which may cause hearing loss

1. Age - Age is the biggest factor when it comes to the loss of hearing, and you may lose the ability to hear as you age. This condition is known as presbycusis. It becomes difficult to understand high-frequency sounds like that of a child or a woman when you get old.

2. Noise - When you are exposed to loud noises for a prolonged period of time, it damages your ears. This leads to loss of hearing. 5% of the total population of the world is affected by noise (the degree of suffering varies). It may be a result of continuous exposure to loud music or a sudden exposure to a loud noise like an explosion.

3. Hereditary disorders - Hearing disorder may be inherited by the dominant or recessive genes of parents in the child. 70-80% of these cases inherit from the recessive genes, whereas 20-25% inherit hearing loss from the dominant genes.

4. Trauma - Serious injuries of the head/ears may cause loss of hearing, which may be either temporary or permanent. When damage is caused to the brain, the brain fails to process the message conveyed by the ears. So even if the ears are totally functional, a person may face the problem in hearing.

5. Perinatal problems - The ototoxic effects on the fetus due to excess intake of alcohol during pregnancy lead to hearing the loss in about 64% of the infants born to alcoholic mothers.

Also, premature birth can be associated with hearing loss due to high risk of being exposed to noise in neonatal units.

Knowing about the causes of hearing loss can lead you a step closer to preventing this disorder as you age.

Here are some useful tips that can help prevent hearing loss:

1. Be more aware - You should be diligent and aware of the situations, which may risk your hearing ability and should try to avoid such situations as much as possible. Limit your exposure to sources of hazardous noises like firearms, firecrackers, concerts and clubs.

2. Take precautionary measures - If your occupation calls for working at an environment of loud noises, use earplugs or earmuffs to block out the excessive noise. Also, make sure that you work in a place where employers take all the necessary measures of noise control under the federal or state regulations.

3. Monitor your use of gadgets - Monitor and control the use of hearing devices, and try to reduce the use of headphones/ earphones as much as possible.
