摘　　要：本文报道对１６只家兔面神经横断伤后，分别行外膜和束膜缝合的两种修复方法处理。于术后４周和８周通过功能恢复及组织学观察表明，两种方法结果无差异，都不能解决神经错向生长现象。通过脸裂恢复情况、神经电图测定及组织切片等检测有髓轴突通过率较客观地反映面神经横断伤后修复情况，且以上３种检测结果有一定平行关系，提示面神经横断伤应进行缝合处理。This paper reports the comparativestudy results of perineu ral and epineural techniques infacial nerve(FN )transection injuries of 16 rabbits. Wefound little difference in recovery of FN function andhistology between epineural and perineura l repairs.Both epineural and perineural sutures on FN have notyet solved the problem of misdirection growth of nervefibers. It is possible to cause the synkinesis movementby using epineural or perineural sutures in human FN.The epineural repair method should be used at the siteof FN trunk which is prescnt as a structure of mixedfasciolae giving out branches, The recovery degree of-eye-openings,ENoG and anastomotic pass-rate of re-generating myeiinated axons could reflect the reco-vervdegree of FN transection objectively.The three parame-ters show a parallel relationship.We suggest that ei-ther epineural suture or perineural suture should becarried out after FN transection injury.
