为探讨不同的治疗方法与Ｂｅｌ面瘫预后关系，报告Ｂｅｌ面瘫１６４例，按治疗方法不同及面神经电图（ＥＮｏＧ）检查结果分为三组。Ａ组，ＥＮｏＧ患侧损失９０％以下；Ｂ１组，损失９０％以上，未行手术减压治疗；Ｂ２组，损失９０％以上，行手术减压治疗。所有病例皆观察１～３年以上，按稍加改进的Ｐｏｒｔｍａｎｎ评分法判定其面肌功能最后得分。结果Ａ组７７例，除３例为良好外，其他皆为满意，平均得分１９．２２±１．１８；Ｂ１组４１例，平均得分１４．４±３．４９；Ｂ２组４６例平均得分１５．４±２．０８。经统计处理Ｂ１组与Ｂ２组差异无显著性（Ｐ＞０．０５），Ａ组结果明显优于Ｂ１组及Ｂ２组（Ｐ＜０．０１）。Ｂｅｌ面瘫的预后主要与病损程度有关，ＥＮｏＧ损失９０％以下时预后良好，损失９０％以上时，减压手术及激素治疗，从统计学角度看，都不能提高疗效
In order to explore the relationship between the different treatment methods and the prognosis of Bel facial paralysis, 164 cases of Bel paralysis were reported, which were divided into three groups according to the different treatment methods and facial nerve electrogram (ENoG). A group, ENoG ipsilateral loss of less than 90%; B1 group, the loss of 90% or more, no surgical decompression; B2 group, loss of more than 90%, surgical decompression. All cases were observed for 1 to 3 years, according to a marginally improved Portmann score to determine the facial muscle function of the final score. Results A group of 77 cases, except 3 cases were good, the others were satisfied with an average score of 19.22 ± 1.18; B1 group of 41 cases, the average score of 14.4 ± 3.49; B2 group 46 patients with an average score of 15 .4 ± 2.08. The difference between group B1 and group B2 was not statistically significant (P> 0.05). The result of group A was obviously better than that of group B1 and group B2 (P <0.01). The prognosis of Bel facial paralysis is mainly related to the degree of lesion, ENoG loss of less than 90% of the prognosis is good, more than 90% loss of decompression surgery and hormone therapy, from a statistical point of view, can not improve the efficacy
