Progress in the prognostic factors associated with the sudden sensorineural hearing loss

突发性聋是指72h内突然发生的,不明原因的感音神经性听力损失,至少在2个相邻频率听力下降20dB以上-（[1]）。发病率为5/10万-160/10万,又被视为耳内科的急症。目前其病因和发病机制尚不清楚,国内外学者对其的基础和临床研究,

Sudden sensorineural hearing loss is a frequent emergency in otology,and there are various patho genesises currently, such as disturbance of inner ear circulation, viral infection and autoimmune response are gener ally accepted. However,the varied therapeutic treatments are mostly disoriented that we can＇t evaluate the clinical effects.
