Otospongiosis is the primary disease of the bones and auditory capsules bone maze. This process produces a more tender bones and reduced. Hearing loss caused by abnormal growths that impede the bones in the middle ear stapes, especially to move properly. Abnormal bone growth that is often the case in front of the fenestra ovale, which separates the middle ear by ear.
The stapes is the smallest bone in the body vibrate freely following the transmission of sound to the ear. When the bone is to be fixed on the surrounding bone, sound vibrations will be inhibited to ears in so that the function of hearing impaired. Otospongiosis is one of the common causes of conductive deafness in adults. The disorder caused due to autosomal dominant disorder that occurs in women as well as men.
This disorder is a disease of the maze of bones, where it formed an area otospongiosis especially in front and near the foot of stapes became fixed. Otospongiosis are relatively common in almost 10% of the population. However, only a small percentage of which is then manifested clinically as a hearing loss. Patients need to be carefully assessed, either through examination or examination with audiologic otologic.
Causes of otospongiosis is still not known clearly. Public opinion suggests that it is derived otospongiosis autosomal dominant. There is also scientific evidence that reveals the presence of measles virus infection that affects otospongiosis. The latest hypothesis states that require specific combinations of otospongiosis genes with exposure to measles virus-so that can be seen in its influence in the hearing.
Some argue that an infection in the bone is a chronic measles predisposing patients to exposed otospongiosis. The material of the virus can be found in osteoblasts on the lesion sklerotik. Some studies have shown that generally occur at the races otospongiosis. About half of them occurred in the oriental population. And very rarely on the negro and the american indians. The population of multiras which included increased incidence risk Kaukasian of otospongiosis.
Otospongiosis is usually described as a disease that is inherited autosomal dominant with incomplete penetration. The degree of penetration is associated with the distribution of lesions lesions on bone capsule otospongiosis maze. Hearing loss and tinnitus is a symptom. Decreased hearing takes place in progressif by number incidence vary, without any cause trauma or infection. Tinnitus is a variation of the tersering and usually runs become more severe due to the degree of hearing loss level.
Research shows that the condition that occurs within the family, or it can be passed down from parents to their children. However, the true cause otospongiosis is not fully understood. People with a family history of the condition that on occasions increasing develop disorders than their counterparts who do not have a relationship with the condition.
Generally, when you have one of your parents with the condition there is a 25 percent chance that you are likely to develop the condition by themselves. If you have two parents who have the condition, the risk You will double and a half. Many studies have shown that women who are middle-aged and white are on the level of risk so far. There are also studies that have connected otospongiosis with all the hormonal changes that women through while they were pregnant. Although the exact cause of the condition is not diagnosed as of yet, there is plenty of evidence that shows the risk increased among those with viral infections.
Before treatment begins, there are some tests that should be done to evaluate the area and extent of the damage sustained. Ear specialist will ask you certain questions relating to the condition and the symptoms that you survive. It is your duty to let the specialist know about symptoms in detail. If the condition does not improve with the use or operation of a CT scan performed to evaluate if there are other reasons that cause an inert condition to remain stagnant in nature or deteriorate further. The symptoms and treatment options for these otospongiosis, there is sure to be well informed about the condition.
