After a brief statistic survey of general aspects the variety of clinical findings in sudden hearing loss is demonstrated by numerous observations. These illustrate the questionable role of supposed causes, the different modes of onset and course of sudden hearing loss, the audiometric findings and concomitant symptoms. The situation of both ears prior to the acute loss seems to be of great importance and offers a frame for classification, which is of clinical relevance. These features and others are discussed with regard to common theories on the etiology of sudden hearing loss. The difficulties in assessing therapeutic effects are pointed out considering the high rate of spontaneous recovery.
在对一般情况进行简要统计调查后，大量观察结果表明了突发性听力损失临床发现的多样性。这些观察结果说明了假定病因的可疑作用、突发性听力损失的不同起病方式和病程、听力测定结果及伴随症状。急性听力损失前双耳的状况似乎非常重要，并为具有临床相关性的分类提供了一个框架。针对突发性听力损失病因的常见理论对这些特征及其他特征进行了讨论。考虑到高自发恢复率，指出了评估治疗效果的困难。
