摘　　要：目的:探讨瞬目反射(BR)、面神经电图(ENoG)检测对面神经炎患儿的诊断价值。方法:20例面神经炎患儿在发病后7-30d分别行BR、ENoG检查。结果:患侧R1、R2及R2’波缺如2例,R1波缺如、R2及R2’波正常3例,R1、R2及R2’波潜伏期延长15例,阳性率100%。患侧面神经运动(M波)潜伏期缺如2例,M波延长、波幅低18例;近端损害8例,远端损害10例,远近端均受累2例。结论:BR检测是诊断儿童面神经炎的早期敏感指标,采用BR、ENoG综合检测可全面、客观地评价面神经损害的程度及部位。Objective：The diagnostic significance of blink reflex （BR） and facial electroneurogam （ENoG） in diagnosing Bell palsy in children has been investigated. Methods：Twenty children with Bell paralysis have been examined by using BR and EnoG at days 7-30 after the onset. Results：The ipsilateral R1 ,R2 ,and R2＇ waves were absent in 2 cases. Three cases only showed no R1 waves,and the resting 15 cases showed delayed latencies of R1 ,R2 and R2＇ waves. M waves of the facial nerve were absent in 2 cases. And the resting 18 patients displayed delayed M waves with low amplitude. The ratio of R1 latency to M latency indicated 8 cases with paroximal injury, 10 with distal injury and 2 with extensive injury. Conclusion：BR can be used as a sensitive parameter for early diagnosis of Bell paralysis in children. BR and ENoG can evaluate the extent and location of injury of the facial nerve.
