外周面神经压碎性损伤已成功地在人体和豚鼠实验中得到恢复。临床上，面神经横断性损伤立即作直接的端一端吻合术可获得最好的运动功能，尤其在神经远端分支。但是，面神经损伤患者中只有小部分可行直接吻合术．绝大多数面神经损伤需其他修复方式。该研究以切断家兔面神经颊支 Peripheral facial nerve crush injury has been successfully restored in human and guinea pig experiments. Clinically, facial nerve transection injury immediately provides the best end-to-end anastomosis for optimal motor function, especially in the distal branch of the nerve. However, only a small percentage of patients with facial nerve injury are eligible for direct anastomosis. The vast majority of facial nerve injury need other repair methods. The study cut off the buccal branch of the rabbit facial nerve
