We performed a 10-year comparative study on 95 cases (98 ears) of mumps deafness and 97 cases (97 ears) of profound sudden deafness and found the following results. The age of onset of deafness was less than 9 years in the majority of patients with mumps deafness, while it was frequently 30-50 years in those patients with sudden deafness. Among these latter patients, no cases occurred under 9 years of age. The incidence of tinnitus and vestibular symptoms was more frequent in the patients with sudden deafness, but no significant difference was noted in cases over 10 years of age. When determining prognosis, no cases of hearing improvement were encountered in mumps deafness, while about 70% of sudden deafness showed improvement.
我们对95例（98耳）流行性腮腺炎致聋患者和97例（97耳）极重度突发性聋患者进行了一项为期10年的对比研究，结果如下。流行性腮腺炎致聋患者多数耳聋起病年龄小于9岁，而突发性聋患者耳聋起病年龄多在30 - 50岁。在这些突发性聋患者中，9岁以下无病例发生。突发性聋患者耳鸣和前庭症状的发生率更高，但10岁以上患者无显著差异。在判断预后时，流行性腮腺炎致聋患者未出现听力改善的病例，而约70%的突发性聋患者听力有改善。
