超长神经血管蒂肌瓣跨面游离移植整复晚期面瘫畸形

CROSSFACIAL FREE MUSCLE GRAFT WITH ULTRALONG NEUROVASCULAR PEDICLE FOR TREATMENT OF LATE FACIAL PARALYSIS

应用超长神经血管蒂肌瓣,争面游离移植Ⅰ期整复晚期面瘫畸形。自1992年,作者等手术整复晚期面瘫7例,术后随访3月～1年,3个月内肉眼可见肌肉活动,6个月面神经末梢潜伏期明显缩短,波幅增大。6～12个月能主动有力收缩口角。该方法既优于传统的晚期面瘫整复方法即筋膜悬吊术及肌瓣转位术,也异于近10多年来O'Brein,Harii等的Ⅱ期面瘫整复术。

We used crossfacial free muscle grafts with ultralong neurovascular pedicle for ong stage facial reanimation. Since 1992, seven cases have been reported to use this method. Followup examination was made between 3 to 12 months postoperatively. The result was satisfactory. Muscle activities were observed within 3 months. The latent periods of the peripheral facial nerves were shortened and the amplitudes increased in six months. Active and powerful contractions of the angle of the mouths could be observed in 6 to 12 months. The method is better than the traditional facioplasty which is used for treatment of late facial paralysis (fascia suspension and muscular flap transposition) and is different from two stage facioplasty first raised by O'Brein and Harii.
