Bell氏麻痹(BP)在临床上常见,年发病率为13～23/10万人口;但双侧麻痹的罕见,综观各家报道,不过占全部BP患者的1%左右。本文报告4例双侧BP患者,男1女3,年龄4～18岁。例1的右侧面肌麻痹较左侧严重;例2正好相反。但2例均于起病时就发现双侧面肌力弱,且总的恢复时间两侧相同。例3先发生右侧面肌麻痹,且其持续时间较长;左侧麻痹系后出现但却先于右侧恢复。例4起初有左侧面肌麻痹,在出现右侧麻痹时左侧麻痹已消失。4例中3例在BP起病前有病毒性或拟诊病毒性疾病,均无糖尿病或传染性单核细胞增多症的实验室或临床证据。全部患者均接受强的松治疗,病情都 Bell’s paralysis (BP) is clinically common, with an annual incidence of 13 to 23 per 100 000 population. However, bilateral paralysis is rare and comprehensive, accounting for about 1% of all BP patients. This article reports 4 cases of bilateral BP patients, 1 male and 3 female, aged 4 to 18 years. Right facial muscle paralysis in Example 1 is worse than the left; Example 2 is the opposite. However, both of the two cases were found to be weak in bilateral facial muscles at the time of onset, and the total recovery time was the same on both sides. Example 3 first paralysis of the right facial muscle occurs, and its duration is longer; left paralysis, but appeared before but recovered in the right side. Example 4 Paralysis of the left facial muscle initially, left paralysis disappeared in the right paralysis. Three of the four patients had either a viral or suspected viral disease before onset of BP, with no laboratory or clinical evidence of diabetes or infectious mononucleosis. All patients received prednisone treatment, the condition is
