突发性耳聋是指突然发生的,可在数分钟、数小时或3d以内,原因不明的感音神经性听力损失,至少在相连的2个频率听力下降20dB以上,多为单侧,偶有双侧同时或先后发生,伴耳鸣、耳堵塞感,伴眩晕、恶心、呕吐,除第Ⅷ颅神经外,无其他颅神经症状,近年来发病呈上升趋势。由于发病原因不明确,故治疗方面缺乏一定的针对性,尚无统一的治疗方案。对该病的早期诊治,可获得较好的治疗效果。近年来,许多学者对该病的病因、发病机制、治疗途径进行了深入系统的研究,笔者在此做一综述。

As the cause of the disease is not clear, so the lack of treatment targeted, there is no uniform treatment. The early diagnosis and treatment of the disease, get better treatment. In recent years, many scholars have made an in-depth and systematic study on the etiology, pathogenesis and treatment of the disease.
