Long term facial paralysis is a serious affliction and upsetting for the patient. Dynamic facial reanimation has become the treatment of choice. Various techniques that use different donor muscles have been developed since the first functional muscle transplant for facial paralysis more than 30 years ago. The concept of using a single muscle was refined into the use of dividable muscle slips such as serratus muscle or separate muscular subunits to avoid the resulting mass movements. Because the results are still not satisfactory, efforts were put into also dividing the donor nerve transplant into corresponding subunits to create a continuous line of individual action. Twenty human cadaveric sural nerves were successfully dissected into three completely separate subunits, transecting the interfascicular bridges. This anatomical study gives the potential to allow an independent triple innervation of three separate serratus anterior muscle slips, so decreasing further the mass movement after facial reanimation.
长期面瘫是一种严重的疾病，会让患者苦恼不已。动态面部重建已成为首选治疗方法。自30多年前首次进行面瘫功能性肌肉移植以来，已经开发出了各种使用不同供体肌肉的技术。使用单一肌肉的概念已细化为使用可分割的肌束，如锯肌或单独的肌肉亚单位，以避免产生的大量运动。由于结果仍不尽人意，人们还致力于将供体神经移植也分割成相应的亚单位，以形成连续的个体动作线。20条人体尸体腓肠神经成功地被解剖成三个完全独立的亚单位，切断了束间桥。这项解剖学研究有可能实现对三个单独的前锯肌肌束进行独立的三重神经支配，从而进一步减少面部重建后的大量运动。
