At present, tinnitus and hearing loss are the main clinical manifestations. A large number of patients with the final diagnosis of sudden deafness.
Sudden sensorineural hearing loss is defined as sudden onset of sensorineural hearing loss in a few minutes, a few hours, or within 3 days, with an unexplained hearing loss of at least 2 of the associated frequencies of hearing loss of 20
More than dB". The above definition is the definition of the "guidelines for diagnosis and treatment of sudden deafness" in China in 2006. It is based on the examination results of audiometry (image results, not text results, please listen and watch to try to save the patients in the doctor visit). In our country the diagnosis standard of this disease is even more stringent than the United States (the United States in 2012 is at least 3 connected frequency hearing more than 30dB in - GB than American Standard strictly rare).
This disease is how to produce, popular understanding is the ear nerve problems. Why is there a problem, for many reasons. The most common are the following. 1 nutrient vessel occlusion (anterior inferior cerebellar artery). The cause of obstruction can be simply understood to be similar to the cause of "stroke", which is more common in older patients; 2. It can be simply understood that a cold is a viral infection of the nose, the disease is an infection of the ear virus; 3 do not know what reason (there are too many clinical diseases).
Patients with tinnitus and hearing loss in our clinic generally do at least two tests: Electrical audiometry and acoustic impedance, which can be understood as binaural hearing and binaural pressure. According to the results of the test can be rough to determine whether there is no deafness, sensorineural hearing loss. If the sensorineural hearing loss is consistent with the above definition can be diagnosed as sudden deafness. According to the 2012 guidelines of the American Academy of Otolaryngology Head and neck surgery, another very necessary examination is the magnetic resonance of the inner ear. The purpose of this examination is simply to exclude the compression of the nerve or tumor caused by auditory nerve dysfunction caused by hearing loss. To simply say that the need for re diagnosis of sudden deafness need to do magnetic resonance exclusion tumor.
On the American "guide" support is a kind of medicine, adrenal cortical hormone, is popular in the sense of hormone (not on hormone discoloration, a lot of clinical disease is the hormone cure, short-term application of small dose of side effects is not so big imagination). Why? No matter what the cause of neurological dysfunction is the result of the final nerve inflammation, swelling, and hormones just inhibit the inflammatory response. China's 06 year guidelines support the use of hormones, antiviral drugs, vasodilators, anticoagulants, neurotrophic drugs, etc.. Why? Because the Chinese people still prefer to start from the cause of disease, the treatment of the disease.
The treatment of this disease by 1-2 treatment medicine in our hospital is a common hormone and vasodilator + neurotrophic drugs (by antiviral or hyperbaric oxygen plus), 14 days in each course. If the first course of treatment can get 90 points, then the course of treatment can only get 10 points, so do not want to have a course of second, the patient's own will is also very important. In the end what will be the effect? A simple understanding of 1/3 patients recovered, 1/3 patients improved (with sequelae), 1/3 patients are completely bad. Elderly patients with vertigo, patients with other underlying diseases are easy to fall after 1/3.
The above is a common understanding of the disease, for reference only.
