Auditic fiber sheath crop: symptoms, causes and treatment

Acoustic neurinoma with the sponsorship of the nerve nerve -nole -like is a benign crop coming from the auditory nerve, that is, the eighth nerve of the nerves of the skull, the tumor is in the corner between the cerebellum and the bridge and it is part of the brain stem in the back of the skull. The big as it occurs during the diagnosis. The presence of this crop has been reported to the elderly between the fourth and sixth decade and is more frequent in women. This crop forms about 10% of total primary crops in the brain. In most cases, the tumors are random, but some form part of a syndrome known as the second nerve fibroid, types of the auditory session sheath tumor contain the most prominent species of the following: 1 Monotherapy vocal crops grow in only one side of the body in 95% of patients, as it can develop from non -genetic intermittent mutations and developed, and these one -ilatoral vocal vocal vocal tuments can occur but it occurs regularly in people between the ages of 30 – 60 years. 2. Double genetic audience neurological crops occur only on both sides of the body in people suffering from genetic disorder, type 2, which is a mutation in chromosome 22 which affects the gene responsible for the production of Xuan cells. Often, these patients have other crops similar to oral tumors in the body, and treatments for these tumors differ from mono -side tumor treatment. Symptoms of the hearing nerve icing include the most important symptoms as follows: 1. Symptoms of primary audience Neuromuscase tumor may not cause clear symptoms in the beginning, but symptoms tend to develop gradually and often include the following: hearing loss that usually affects only one ear. Hearing sounds that come from within the body. Feel that you are moving or turning. 2.. Symptoms of highly heard -niced sheaths can sometimes cause hearing -like sheath crop: persistent headaches. A temporary or double vague vision. Numbness, pain or weakness on one side of the face. Problems with the coordination of the limbs or on one side of the body. Soft sound or problems with swallowing. Causes and factors of the risk of hearing transmitter sheath -crop in the following are an explanation of the most prominent causes and factors of the risk of developing hearing fiber sheaths: 1. The causes of the development of hearing fiber sheaths can be linked to the cause of the hearing -sensitive junk with a problem in the gene on chromosome number 22, where these genes have a protein Cells cover that cover the cells that cover nerves. Experts do not know the causes of this problem in the gene in most cases of hearing nerve crop, as there is no cause. This defective gene is also inherited in type 2 fibroid crop, which is a rare deviation that usually involves the growth of crops in hearing nerves and balance on both sides of the head. 2.. The risk of developing the audience nerve sheath crop is the only risk factor for the incidence of hearing nerve sheath sheath, is the infection of one of the parents with a rare genetic disorder from the second type of fibroid crop, but the second type of fibroid is only about 5% of cases of hearing center. The characteristic feature of Type 2 nerve crop is the development of non -cancerous crops in hearing nerves and balance on both sides of the head, as well as on other nerves. The complications of the audience nerve sheath, if left untreated, can cause the tumor to grow significantly to cause pressure on the brain stem, as the tumor can prevent the flow of the cerebrospinal fluid between the brain and the spinal cord, which can cause the accumulation of the fluid in the brain. Since the skull is a closed structure, excess fluid in the brain can push the brain, causing movement incidence, lack of coordination, headaches and confusion. The diagnosis of the hearing nervous sheath crop contains the most prominent diagnostic methods of the following: 1. Hearing test in this test performed by a hearing specialist who hears voices directed at one ear, where a hearing specialist offers a set of sounds with different sounds and asks you to refer to each time you hear the sound. Each tone is repeated at low levels to know when you barely hear, and a hearing specialist can also provide different words to determine your ability to hear. 2. Imaging is usually used by MRI with a contrast paint to diagnose hearing nerve crop, as this photography test can reveal up to 1-2 millimeters of small crops. If magnetic resonance imaging is not available or for some reason you cannot perform an MRI test, computerized tomography can be used, but CT scan may not be revealed over very small crops. The treatment of the hearing -nuwic sheath crop the crop treatment may vary depending on the size and growth of hearing fiber sheaths, your overall health and the severity of the symptoms, and the most prominent methods of treatments include the following: 1. Observation if you have a small tumor that does not grow slowly, and a little signs or symptoms or monitor, you can do. not for more powerful treatment. Your doctor may recommend that you usually perform regular photography and audience controls every 6-12 months to determine if the crop is growing and how fast it is. If the tests show that the crop is growing or if the crop causes advanced symptoms or other problems, you may need to undergo treatment. 2. Surgery may require surgery to remove the hearing -centered fiber sheath, especially if the crop continues to grow and become much larger and cause symptoms, your surgeon can use one of the many techniques to remove the crop, depending on the size of the crop, hearing condition and other factors. The purpose of surgery is to remove the crop and maintain the facial nerve to prevent the paralysis of the face; The removal of the entire crop may not be possible in some cases. For example, if the tumor is very close to important parts of the brain or facial nerve. 2. Radiotherapy includes the following: Radiological surgery may recommend your doctor for a type of radiotherapy known as radiological surgery with corruption, often used when the tumor is small, ie a diameter of less than 2.5 centimeters, or if you are the elderly, or you cannot resist health reasons. Divided radiotherapy provides a small dose of radiation for the crop over multiple sessions as it is performed to reduce the growth of the crop without damaging the surrounding brain tissue. Proton -Radiation Therapy. This type of radiotherapy uses high -energy packages of positively charged particles called protons, where protons are linked to the affected area with targeted doses to treat crops and reduce exposure to radiation to the surrounding area. Prevention of hearing nerves cannot prevent the disease.
