贝尔麻痹的发病诱因调查

Bell’s palsy: the inducing factors survey

目的调查贝尔麻痹发病的诱因,对防治该病提供理论基础。方法2005年2～5月对在我科就诊的262例贝尔麻痹患者采用问卷形式进行了一项可能性诱因的回顾性调查。结果262例患者发病时平均年龄39±17岁。患者男女比率和左右侧患病比率都为48%比52%。48名患者否认发病前存在问卷所列诱因,其余214例存在问卷表中诱因,占患者总数的81.7%。其中发病前有明确受凉史139例,占53.5%;过度疲劳者59例,占22.5%;上感49例,占18.7%;前次发病史(复发)31例,占11.8%;心理压力30例,占11.5%;有明确家族史20例,占7.6%;妊娠4例,占1.5%;患侧牙龈感染4例占1.5%。结论贝尔麻痹可能是一组面瘫疾病,大部分患者存在可能性诱因,进一步的研究有可能对贝尔氏麻痹的命名、诊断及治疗产生细分作用。对受凉、疲劳等可能性诱因的预防和处理有可能减少贝尔麻痹的发生。

OBJECTIVE To investigate the inducing factors of Bell＇ s palsy. METHODS From February to May 2005, 262 outpatients of Bell＇ s palsy were surveyed for9inducingfactors. RESULTS The mean age of onset was 39 ± 17 years old. The ratio of male to female and of left to right were 48：52. Fortyeight patients denied all inducing factors, while 214 patients （81.7 %） had at least one factor. Cold was found in 53.5 % of the patients, fatigue in 22.5 %, viral infection in 18.7 %, recurrence in 11.8 %, psychological stress in 11.5 %, family history in 7.6 %, puerperal period in 1.5 %, and molar infection of the affected side in 1.5 %. CONCLUSION Bell＇ s palsy is likely to be a set of disease. Most of patients with Bell＇ s palsy had inducing factors. Avoid these factors may reduce the incidence of Bell＇ s palsy. Further investigate will fractionize Bell＇ s palsy to several diseases including true idiopathic peripheral facial paralysis and some definite diseases.
