应用面神经次要分支修复重要分支的效果观察

Clinical application of unimportant branches of facial nerve to repair important ones

目的:探讨应用面神经次要分支修复重要分支的可行性及临床效果。方法:应用面神经颈支修复下颌缘支,上颊支修复颧支缺损。测量缺损的神经长度后,切断颈支和上颊支远端,旋转至需要修复的下颌缘支及颧支远断端。手术在双人双目手术显微镜下进行,用9-0无损伤缝合线吻合2～4针。应用颈支修复下颌缘支缺损5例,应用上颊支修复颧支缺损7例。结果:颈支修复下颌缘支5例,术后3个月恢复2例,术后6个月恢复3例。上颊支修复颧支7例,术后3～4个月功能完全恢复。结论:应用面神经颈支修复下颌缘支缺损及应用上颊支修复颧支缺损在临床上是完全可行的,并可取得较好的修复效果。

PURPOSE： To study the feasibility and clinical effect of repairing important branches of facial nerve （zygoroatie and marginal mandibular branches） with unimportant ones （upper buccal and cervical branches）. METHODS：The defect of zygomatic and marginal mandibular branches was repaired with upper buccal and cervical branches, respectively. After the length of facial nerve defect was measured, the distal part of the upper buccal and cervical branches with peripheral tissue was used to repair the defect. Under operating microscope, nerve anastomosis was performed with 9-0 suture. 5 cases suffering from defect of marginal mandibular branches were repaired with cervical branches, and 7 cases with defect of zygomatic branches were repaired with upper buccal branches. RESULTS： In 5 cases suffering from defect of marginal mandibular branches, 2 eases recovered in 3 months, and 3 cases recovered in 6 months; In 7 eases suffering from defect of zygomatie branches, all recovered in 3-4 months. CONCLUSION： Repair of defect of zygomatic and marginal mandibular branches with upper buecal and cervical branches is feasible and the result is acceptable.
