Idiopathic axillary, also known as idiopathic sudden sensorineural hearing loss, refers to a sudden onset of sensorineural hearing loss of unknown cause, referred to as sudden paralysis. Usually in a few minutes or hours, a small number of hearing loss within 3 days, accompanied by tinnitus and dizziness. Mostly unilateral onset, binaural axillary is rare. The treatment effect is directly related to the time of the visit and should be treated as soon as possible.
The etiology and pathogenesis are still unclear.
There are many reasons for sudden hearing loss, but most scholars believe that it is mainly due to inner ear blood circulation disorder, viral infection, viral and vascular comprehensive factors, labyrinth rupture, vascular dysfunction, trauma, poisoning, tumor and other reasons.
The sudden onset of the cause cannot be found, called idiopathic axillary, and its possible causes are mainly the following:
1 virus infection
One of the main causes of doctrine. According to clinical observations, many patients have pre-existing symptoms before the onset of the disease. A number of infected viruses have been detected by serum tests on patients, such as influenza B, mumps virus, and cytomegalovirus.
2 inner ear blood supply disorder
It is an important factor in the onset of this disease. The inner ear vein and the inner auditory artery and the branch are terminal blood vessels. Therefore, the inner ear blood supply disorder is likely to impair the hearing function. Vasospasm of the inner ear, blood flow disorders, formation of microthrombus, hemodynamic changes, increased blood viscosity, etc. are the causes of abruptness.
3 autoimmune dysfunction
The pathological mechanism of sudden deafness can be manifested as abnormal body fluid and cellular immunity. The inner ear immune response belongs to the protective mechanism of the body, but it is too strong to cause membrane labyrinth damage.
1 hearing loss
Suddenly, most occur in minutes or hours, and a few quickly fall to the lowest level in 3 days. Most of them have moderate and severe sensorineural hearing loss, and a few can be extremely severe or even full. The incidence is mostly in the early hours of the morning or shortly after getting up, often without warning, but there may be incentives, such as overwork, cold, cold, emotional or drinking.
Tinnitus occurs before and after deafness, accounting for 70%, mostly low-pitched or high-pitched tinnitus. Some patients may over-emphasize tinnitus and ignore hearing loss.
Some patients are accompanied by varying degrees of dizziness, varying degrees. A small number of patients will be misdiagnosed as Meniere’s disease, but the disease usually relieves after a few days, and there is no recurrent vertigo.
4 ear blockage
Usually the ear blockage appears before the deafness, and some patients may feel numbness or heavy feeling in the ear.
Due to the particularity of the disease, we strive to use the drug as soon as possible to intervene. According to the cause of the drug, such as drugs to improve blood supply to the inner ear, nutritional neuropharmaceuticals, antiviral drugs and hyperbaric oxygen therapy to promote metabolism.
