应用神经电图对９６例周围性面神经炎患者进行检测，并对其中４７例患者进行随访发现：患者额肌、上唇方肌神经电图检查时其波幅、传导速度患侧较健侧低；在临床恢复过程中波幅，传导速度有恢复趋势；病情预后差者波幅、传导速度比预后好者下降更明显。面肌神经电图检查对估计周围性面神经炎预后有帮助。 Ninety-four patients with peripheral facial neuritis were examined by electrogram. Forty-seven of them were followed-up and found that the amplitude and conduction velocity of the frontal muscle and the upper lip muscle were lower in the electromyogram than those in the healthy side. During the course of clinical recovery, the amplitude and conduction velocity had a recovery tendency. The amplitude and conduction velocity of poor prognosis were more obvious than those with good prognosis. Facial neuromuscular examination is helpful in estimating the prognosis of peripheral facial neuritis.
