In this study we correlated results of ultrasonographic muscle thickness and contractility with facial electromyography (EMG) in patients with unilateral peripheral acute or chronic facial palsy.
Two hundred twenty measurements of 4 facial muscles (frontalis, orbicularis oculi, zygomaticus, and orbicularis oris) were performed in 44 patients.
Facial muscle thickness at rest and during muscle contraction correlated best with EMG insertional activity, and facial muscle contractility correlated with EMG voluntary activity. The correlation was much higher at >14 days after onset of facial palsy. The orbicularis oris, followed by the frontalis muscle, showed the best correlation between ultrasound and EMG.
Quantitative ultrasound of facial muscles helps confirm the results of facial EMG and is of particular additional value in the first 14 days after onset when the reliability of EMG is low.
在本研究中，我们将单侧周围性急性或慢性面瘫患者的超声肌肉厚度和收缩性结果与面部肌电图（EMG）进行了关联。
对44例患者的4块面部肌肉（额肌、眼轮匝肌、颧肌和口轮匝肌）进行了220次测量。
静息和肌肉收缩时的面部肌肉厚度与肌电图插入活动相关性最佳，面部肌肉收缩性与肌电图自主活动相关。面瘫发病14天以上时相关性更高。口轮匝肌，其次是额肌，在超声和肌电图之间显示出最佳相关性。
面部肌肉的定量超声有助于确认面部肌电图的结果，并且在发病后的前14天，当肌电图可靠性较低时具有特别的附加价值。
