摘　　要：目的:运用面神经运动传导检查比较面神经颊支和颞支运动传导功能恢复的异同。方法:2001-09/2003-07来源于成都中医药大学附属医院、四川大学华西医院、绵阳市中医院、四川省人民医院等4个临床研究中心的贝尔麻痹患者480例,经过4周治疗,愿意接受并完成面神经颊支和颞支运动传导检查的患者分别有205、246例。其中,采用西药常规治疗的有69、83例,采用西药常规治疗加针灸治疗的有66、80例,采用针灸治疗的有70、83例。分别进行治疗前后以及患健侧面神经颊支和面神经颞支运动传导检查比较。结果:①患侧治疗后面神经颊支动作电位潜伏期明显缩短[(2.95±0.68),(3.08±0.69)ms,P<0.05],治疗后动作电位波幅未见明显改善(P>0.05)。②治疗后面神经颞支动作电位波幅明显增高[(518.85±496.57),(391.47±468.69)μV,P<0.01],潜伏期无明显改善(P>0.05)。结论:贝尔麻痹患者患侧治疗后面经神经颊支动作电位潜伏期改善明显,动作电位波幅未见明显改善;治疗后面神经颞支动作电位波幅改善明显,而潜伏期无明显改善。面神经运动传导动作电位波幅是反映神经轴索变性的客观指标,贝尔麻痹治疗后面神经颊支轴索恢复不如颞支好,与临床表现一致。AIM： To compare the motor conduction functional recovery of buccal and temporal branches detected with motor conduction of facial nerve branches. METHODS： 480 patients with Bell＇s palsy from Affiliated Hospital of Chengdu University of Traditional Chinese Medicine,West China Hospital of Siehuan University, Traditional Chinese Medicine Hospital of Mianyang, Sichuan Provincial People＇s Hospital were selected. After 4 weeks treatment, 205 and 246 patients were willing to accept motor conduction of facial nerve branches test including 69 and 83 cases treated with western medicine, and 66 and 80 cases treated with western medicine and acupuncture and moxibustion and 70 and 83 cases treated with acupuncture and moxibustion. The motor conduction of facial nerve and temporal nerve before and after treatment were detected and compared. RESULTS：①The latency of buccal branch of facial nerve in affected side was shortened after treatment [（2.95±0.68）, （3.08±0.69） ms, P 〈 0.05], but the amplitude was not improved after treatment （P 〉 0.05）. ② The amplitude of temporal branch of facial nerve in affected side was greatly improved after treatment [（518.85±496.57）, （391.47±468.69） μV, P 〈 0.01], but the latency was not significantly improved （P 〉 0.05）. CONCLUSION： The latency in action potentials of buccal branch of facial nerve in affected side of patients with Bell＇s palsy is greatly improved, but the amplitude is not after treatment; the amplitude of temporal branch of facial nerve in affected side is greatly improved after treatment, but the latency is not. The amplitude in action potentials of motor conduction of facial nerve is objective index for the axonal degeneration of facial nerve. The recovery of temporal branch of facial nerve is better than that of the buccal branch in terms of treating Bell＇s palsy, which is similar to clinical manifestation.
