Abstract：
The purpose of this study was to evaluate the facial nerve recovery of patients with traumatic facial nerve transections after tension-free end-to-end nerve epineural anastomosis during the acute phase. A total of 11 patients with traumatic facial nerve transections during the acute phase were surgically treated in the authors\' department from November 2016 to August 2022. The case data and imaging data were collected from the patients, and the House-Brackman evaluation system of the facial nerve was applied to assess the recovery of facial nerve function, and the higher the grade, the worse the facial nerve function. Of the patients, 90.9% recovered to H-B grade II or below, and there were differences in the degree of recovery of the facial nerve function among the branches, and the ones that recovered to H-B grade II or below after surgery were 100% of the zygomatic branch, of which 80% were H-B grade I, 100% of the buccal branch, of which 44.4% were H-B grade I, 88.9% of the marginal mandibular branch, and 66.7% of the temporal branch. The study showed that the recovery rate of young patients was better than that of middle-aged and old people, and the best recovery of each branch of the facial nerve was the zygomatic branch, followed by the buccal branch, the marginal mandibular branch, and the worse was the temporal branch.
摘要：
目的评价急性期无张力端对端神经硬膜外吻合术后创伤性面神经横断患者的面神经恢复情况。从2016年11月至2022年8月，作者部门共手术治疗了11例急性期创伤性面神经横断患者。收集患者的病例资料和影像学资料,并应用House-Brackman面神经评价系统评估面神经功能的恢复情况,分数越高,面神经功能越差.在患者中，90.9%恢复至H-B等级II或以下，各支面神经功能恢复程度存在差异，手术后恢复到H-BII级或以下的是100%的骨分支，其中80%为I级H-B,100%的颊支，其中44.4%为I级H-B，下颌边缘支的88.9%，和66.7%的时间分支。研究表明,年轻患者的康复率优于中老年人,面神经的每个分支的最佳恢复是zy支，其次是口腔分支，下颌边缘分支，更糟糕的是颞叶分支。
