Facial paralysis is either congenital or acquired, and of varying severity, which leads to an asymmetrical or absent facial expression. It is an important disability both from the aesthetic and functional points of view. Between 2003 and 2008, at the Department of Maxillofacial Surgery, University of Parma, Italy, 21 patients with facial paralysis had their faces reanimated with a gracilis transplant reinnervated by the masseter motor nerve. All free-muscle transplants survived the transfer, and no flap was lost. Facial symmetry at rest and while smiling was excellent or good in most cases, and we found an appreciable improvement in both speech and oral competence. We consider that the masseter motor nerve is a powerful and reliable donor nerve, which allows us to obtain movement of the commissure and upper lip similar to those of the normal site for degree and direction. There may be a role for the masseter motor nerve in innervation of patients with facial paralysis.
面瘫可分为先天性和后天性，严重程度各异，会导致面部表情不对称或缺失。从美学和功能角度来看，它都是一种重要的残疾。2003年至2008年间，在意大利帕尔马大学颌面外科，21例面瘫患者通过咬肌运动神经再支配的股薄肌移植使面部恢复了活动功能。所有游离肌肉移植在转移后均存活，无皮瓣丢失。在大多数情况下，静息和微笑时的面部对称性极佳或良好，并且我们发现言语和口腔功能都有明显改善。我们认为咬肌运动神经是一种强大且可靠的供体神经，它能使我们获得类似于正常部位的口角和上唇在程度和方向上的运动。咬肌运动神经在面瘫患者的神经支配中可能发挥作用。
