对长期面瘫肌肉已经萎缩的患者,应用游离肌肉移植(肌纤维发生变性和再生)或吻合神经血管的肌肉移植(大多数肌纤维得以成活)恢复面部的正常运动功能,效果尚不确定。作者比较了将游离肌肉和持续灌注的肌瓣移位于猴面部后,肌肉所发生的结构与功能变化.取32只成年猴,自下肢切取游离肌肉(free grafts)或自同侧颞肌切取去除神经支配的肌瓣(temporalisflap),以其取代面肌。用保留的面神经颊支重新使移植肌肉或肌瓣恢复神经支配,移植后90天,检查对照肌肉,移植肌肉和肌瓣的大体形态,收缩性能和肌纤维变化。结果表明,与肌瓣相比,游离肌肉移植更能适应
For long-term facial paralysis in patients with muscle atrophy, the application of free muscle grafts (degeneration and regeneration of muscle fibers) or muscle grafts matching neurovascular graft (most muscle fibers survive) restore facial normal motor function, the effect is uncertain. The authors compared the structural and functional changes that occur in the muscle following the mobilization of free muscle and continuous perfusion muscle flaps on the monkey's face.All 32 adult monkeys were either free grafts or autologous Remove the inneris muscle flap (temporalisflap), to replace the facial muscles. Grafts of the transplanted muscle or muscle flap were reinnervated with the remaining facial nerve buccal branches, and the general morphology, contractility and muscle fiber changes of the control muscle, transplanted muscle and muscle flaps were examined 90 days after transplantation. The results show that, compared with the muscle flap, free muscle transplantation more adaptable
