摘　　要：目的探讨面神经电图和瞬目反射对面神经炎的诊断和预后评估的价值。方法对68例面神经炎患者在发病1周内进行面神经电图和瞬目反射的检测,并进行随访6个月。结果瞬目反射测定患者R1、R2和R2'缺失8例,R1缺失、R2和R2'潜伏期延长18例,R1、R2和R2'潜伏期延长42例;面神经电图测定缺失6例潜伏期延长及波幅降低39例,瞬目反射检出率明显高于面神经电图(P<0.01)。复查时,26例重度损害患者中6例可检出各波形,好转率为23.1%;27例中度损害患者21例痊愈,3例好转;15例轻度损害患者经过1～3个月均痊愈。结论瞬目反射可以作为面神经炎早期诊断的客观指标,对判断面神经炎预后评估有重要作用。Objective To evaluate facial nerve electrogram and blink reflex in patients with facial paralysis.Methods Facial nerve electrogram and blink reflex were measured in 68 patients with facial paralysis and 6 months after the onset.Results Missing R1,R2 and R2＇ waves were absent in 8 cases;missing R1,the latencies of R2 and R2＇ were prolonged in 18 cases;the latencies of R1,R2 and R2＇ were prolonged in 42 cases.Blink reflex was higher than that of the facial nerve electrogram（P0.01）.When reviewed,6 cases of 26 cases of severe damaged patients could be detected with various waveforms,the improvement rate was 23.1%;21 cases of 27 moderate damaged patients recovered,3 cases improved;after 1～3 months 15 cases of mild damaged patients recovered.Conclusion Blink reflex could be used as an objective index for the early diagnosis of facial paralysis,and it has an important role in evaluating the degrees of facial nerve and prognosis.
