Ear serves as a means of hearing and balance. In order for these two functions are running, the ear should be kept. Unfortunately, many people who overdo wrong in maintaining the cleanliness of the ear. For example, the ear.
The ear consists of the outer, middle and deep. The third part of this collaboration capture sound waves and make it sound real. Initially, the sound waves received by the outer ear. The outer ear consists of the leaves and the ear canal. "Auricle accommodate voice, which is then channeled into the ear canal," said dr. Darnila Rani, Sp.THT of RSCM.
Of the ear canal, sound and then enter the middle ear through the ear drum. Behind the eardrum, there is a loss of bone that resembles a chain. These bones are interconnected in the joints and serves to deliver sound waves to vibrate the eardrum, and to the inner ear.
In the inner ear are receiving device called the cochlea. Inside the cochlea are nerve endings, fluids, and organs were floating. Sound waves are delivered drum and ear bones will vibrate the fluid in the cochlea, thus making organs floating moving and touching the ends of the auditory nerve. Process that was using mechanical energy is then converted into electricity, and delivered to the brain so that we hear the sound.
While as a balancing tool, the process is more complex. The process occurs in the inner ear. Ear in cooperation with other organs such as the eyes, joints, brain and others. If there are two organs are not functioning, then we would be lost balance.
DANGER ferret
Ear shape is designed to anticipate the entry of dirt. Angled ear canal which makes dirt, such as dust or insects, it is difficult to penetrate the deeper part. Task banish dirt also do hair gland located in the front after the ear canal. Here also produced sap called ear wax. We know him as tai ear or sap. Tai ear is what will catch dirt and clean themselves.
People often mistakenly think tai ear as dirt. In fact, its function is very important to clean the dirt coming. In alamaiah, dry dirt will enter and exit itself. "Tai ears should not be discarded, unless the clot and block the ear canal and thus block the entry of sound waves to the inner ear," said Darnila. Moreover, there are many cases of people suffering from this sap clotting.
In normal levels, tai ears just cover the surface of the wall of the ear. If cleared, the sap will be produced again. Thus, the ears should not be cleaned by scraping. Just clean the outside of course, that leaves the ear canal and estuary. "Part deeper than that, life did not need to be cleaned," said Darnila.
One that people often do is scrape the ears. Not many people know that it will lead to ear scraping gum and encouraged ear to the deeper part is not the place. If the sap is cleared, then the sap will be produced again. If pengorekan done continuously, driven sap will accumulate and clog, so the hearing was declined because the sound waves can not be channeled properly.
Scrape the ear can also lead because our ears the clash of angular shape. This clash will result in swelling or bleeding. Pengorekan are too loud or inside also can lead to trauma, plus the walls of our ears bleed easily.
There's more, scraping the ear can also cause collapse. You may have experienced coughing when nosing ear. Well, this is due to nerve reflex pagus contained in the walls of the ear. Pagus nerve extends into the throat, chest to the abdomen. Cough is a reflex light. Reflexes are heavy and can lead to dangerous collapse.

HOME NOT SYMMETRIC
Scrape the ear can also cause infection. "Severe infections and are in sensitive areas can cause decreased hearing quality, even made a face so lopsided (asymmetric)," said Darnila.
One contained in the ear nerve is the facial nerve. This nerve is located behind the ear canal. Its function is to move facial muscles and as part of that support hearing. "Although this nerve is protected bone, but if infection or other disorders had about it, then it could lead into a wry face, the eyes can not be closed, and the other, called the facial nerve paralysis."
Infections due to pry too hard can be shaped like a festering boil. Infections can occur in the ear canal, hair glands, even down to the middle ear behind the eardrum. In addition to scraping, middle ear infection called congek can also be caused by an infection in the respiratory tract, which comes from the back of the nose and then spread to the fallopian tubes that connect eskafius cavity behind the nose to the middle ear. "If the production of pus more, the drum can rupture or leak. As a further consequence, the hearing will be disturbed, "said Darnila.
In the ear there are a lot of nerves. That is why the ear is very sensitive. When we are sick tonsils, toothache or sore throat, ear ache as well, because our ears through which the nerves of taste. This will divert nerve pain in other areas up to the ears.
AVOID LOUD MUSIC
Many things could be the cause of the decline in the quality of hearing. In light level disturbance, people will only be able to hear sound with a capacity of 25-40 decibels alone, moderate 40-60 decibels, and if more than 60 decibels means are in early stages of weight.
The causes varied, ranging abnormalities in the outer ear to the inside. Abnormalities in the outer ear can be caused by blockage of the lymph ear, foreign bodies, abscess, or tumor. Disturbances in the middle ear as drum rupture, bleeding in a collision in the accident, breakdown of ossicular chain or discharge due to allergies.
While in the inner ear, disruption of "unconscious" or the death of hair cells that convert mechanical vibrations into electricity and deliver it to the brain. "Fainting" or hair cell death caused by noise trauma, for example, heard too long and often sounds very harsh, spreading infection of the middle ear or due to drug toxicity. Through blood circulation, toxins from drugs get to the inner ear.
Diseases such as high blood pressure and diabetes can also reduce hearing. Because the disease can be caused damage to blood vessels. "As a result, the inner ear as terminals do not get enough food," said Darnila. Some foods can also cause hearing loss if it causes constriction of blood vessels. Examples of salt, fat and cigarettes. The fall of hearing due to high blood pressure, diabetes, and drug toxicity can strike of both ears. While other causes only attacking ear disorder. Keep in mind, a disturbance in one ear does not spread to the other ear.
Most disturbance in the outer ear and the middle ear can be overcome. Meanwhile, if the inner ear is rather difficult. "If the hair cells in the inner ear only" unconscious ", for example as a result of listening to disco music for two hours, then the hearing will come back after some time avoid this loud music. However, if too often listen to music or sounds very hard, it could have broken the hair cells and ultimately the quality of damaged hearing. Generally it can not be repaired, "said Darnila.
