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

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

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!

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.
