摘要
目的分析贝尔麻痹(Bell′s麻痹)患者早期面神经运动传导检测指标,探讨其在贝尔麻痹早期诊断中的作用。方法对22例贝尔麻痹患者在起病1周内进行双侧面神经运动传导对比检测,比较患、健侧面神经运动传导动作电位潜伏期、波幅,分析其与早期诊断的关系。结果 22例患者双侧面神经各支均引出运动传导动作电位,患侧面神经各支动作电位波幅较健侧明显下降,差异有统计学意义(P<0.05);患侧面神经各支动作电位潜伏期与健侧相比,差异无统计学意义(P>0.05)。结论面神经颞支和颊支的运动传导波幅检测可作为面神经损伤的早期诊断指标之一。颧支受累较颞支和颊支相对少,它是否能作为损伤程度及预后判定的指标尚需进一步观察。
Objective To analyze the indicators of motor conduction of facial nerve branches in patients with Bell＇s paralysis, and discuss the function of motor conduction in the early diagnosis. Methods The motor conduction of healthy and affected sides in 22 patients with Bell＇s paralysis were detected and compared one week within onset. Compare the latent period and wave amplitude of the two sides as well as its relation with early diagnosis in both sides. Results The wave amplitude was detected in all patients, and the amplitude of facial nerve in affected side declined. There was a significant difference in wave amplitude between the affected side and unaffected side （ P 〈 0. 05 ）. The latency of facial nerve in both sides showed no statistical difference （ P 〉 0. 05 ）. Conclusion The wave amplitude in action potentials of temporal and buccal branches of facial nerve is one of the objective indexes for the early diagnosis of Bell＇s paralysis. Further observation is needed to determine whether it can be an index for injury level and prognosis.
