Sudden onset sensorineural hearing loss is a medical emergency that continues to be poorly understood despite being recognized in the literature since 1944 (De Kleyn, 1944). A commonly used criterion to qualify for this diagnosis is a sensorineural hearing loss over three contiguous pure-tone frequencies of 30 dB or more that develops within 72 hours. The vast majority of cases are unilateral and the estimated annual incidence is 20 per 100 000 persons (Nosrati-Zarenoe et al, 2007). A cause for the hearing loss is only identified in up to 10% of cases but 50% of patients will improve spontaneously (Penido et al, 2009).
突发性感音神经性听力损失是一种医疗急症，尽管自1944年（德克莱恩，1944年）在文献中被认识以来，人们对其了解仍然甚少。用于符合该诊断的常用标准是在72小时内出现三个连续纯音频率听力损失30dB或更多的感音神经性听力损失。绝大多数病例为单侧性，估计年发病率为每10万人中有20例（诺斯拉蒂 - 扎雷诺埃等人，2007年）。仅在高达10%的病例中确定了听力损失的原因，但50%的患者会自发改善（佩尼多等人，2009年）。
