方法：我科2010-09/2013-10收治下睑纵形裂伤合并下泪小管断裂患者37例37眼行泪小管断端吻合及下睑裂伤缝合术，术中综合运用直视法、探针插入指引法及猪尾巴弯探针法寻找到泪小管鼻侧断端，置入硅胶管作为泪道支撑物，并采用“Z”形皮瓣修复下睑纵形裂伤，随访3mo～2a。

结果：患者37例均能顺利寻找到泪小管鼻侧断端； 泪道通畅31例(83.8%)，好转5例(13.5%)，无效1例(2.7%)，总有效率97.3%； 眼睑修复良好，瘢痕细小，眼睑外观、功能基本正常。

结论：术中综合运用直视法、探针插入指引法及猪尾巴弯探针法均能顺利找到鼻侧断端； 选用硅胶管作为泪道支撑物效果良好； “Z”形皮瓣修复下睑纵形裂伤对眼睑形态、功能的恢复效果满意。

METHODS: From September, 2010 to October, 2013, a total of 37 patients(37 eyes)with lower eyelid longitudinal laceration combined with lower lacrimal canaliculi disruption were operated for anastomosis of lacrimal canaliculi disruption and suture of lower eyelid longitudinal. Different methods to search for the nasal cut ends of lacerated lacrimal canaliculi, such as “under a microscope directly”, “guided by probing needle” and “pigtail curved probe”. Then, to repair lower eyelid longitudinal laceration with Z-plasty transposition flaps. Follow up was 3mo～2a after operation.

RESULTS: All nasal cut ends could be found successfully on 37 patients; Lacrimal duct unobstructed in 31 patients(83.8%), improved in 5 patients(13.5%), invalid in 1 patient(2.7%),the overall successful rate was 97.3%; the eyelids repair was satisfactory, small scars, the appearance and function was normal.

CONCLUSION: The nasal cut ends can be found successfully by “directly under a microscope”, “guided by probing needle” and “pigtail curved probe”; the effect of silicone drainage tube used as lacrimal canaliculi bracket is satisfactory; most patients gained excellent recovery for both appearance and function after Z-plasty.
