特发性面神经麻痹(Bell’s Palsy, BP)的特点为:(1)一侧面肌完全性或部分性麻痹;(2)无其他神经系统疾病的症征;(3)无耳或后颅窝疾病的症征.BP在临床实践中很常见,每年发病率为12～23/10万.反之,双侧BP则罕见.文献中Adour和Swanson在308例BP中仅发现1例.Hauser在121例BP中发现2例,Leibowitz在582例BP中发现5例为双侧BP.本文报告4例双侧Bell’s面肌麻痹患者,男1例,女3例,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有双侧面肌无力,且总的恢复时间两侧相同.例3先发生右侧面肌麻痹,且其持续时间较短期出
Bell’s Palsy (BP) is characterized by: (1) a complete or partial paralysis of the lateral facial muscles; (2) no signs of other neurological disorders; (3) auricle or posterior fossa diseases BP is very common in clinical practice, the annual incidence of 12 to 23/100 000. On the contrary, bilateral BP is rare in the literature Adour and Swanson in 308 cases of BP found only in 1. Hauser in 121 cases BP found in 2 cases, Leibowitz in 582 cases BP found in 5 cases of bilateral BP.This report reports 4 cases of bilateral Bell’s facial paralysis patients, 1 males and 3 females, aged 4 to 18 years old Lateral paralysis more severe than the left, the opposite of case 2, but both were found in the onset of bilateral facial weakness, and the total recovery time on both sides of the same .Figure 3 first right facial muscle paralysis, And its duration is shorter period out
