摘要
目的探讨泪小管断裂修复术中，逆行插管注水法寻找鼻侧断端的可行性以及丝裂霉素C（MMC）预防吻合口纤维化的临床疗效。方法对46例（46眼）外伤性泪小管断裂，在鼻内窥镜下从鼻泪管下端开口逆行插管注水，寻找鼻侧断端，并于术中及术后应用MMC。结果46眼均顺利找到鼻侧断端，成功吻合。随访6-36月：泪溢症状消失，冲洗泪道通畅35眼；泪溢症状减轻，冲冼泪道通畅7眼。有效率为91．30％；泪溢症状无改善，冲洗泪道不通4眼，无效占8．70％。结论对外伤性泪小管断裂，尤其是上、下泪小管同时断裂或泪总管断裂，采用逆行插管注水是寻找鼻侧断端的可靠方法。MMC可抑制吻合口的纤维化，提高疗效。
Objective To study the practicability of retro-irrigation for searching canalicular nasal breakage and clinical results of MMC preventing the junction＇s fibrosis. Methods In 46 cases of traumatic lacrimal canalicular laceration, retrograde irrigating from the nasolacrimal canal＇ s opening was used to search the nasal breakage under nasal endoscope and MMC was used during operation. Results 46 cases of nasal breakage were found and connected successfully. Follow-up ranged from 3 to 36 months, symptom of epiphora disappeared, the lacrimal passage was passable in 35 cases, relieved in 7 cases （911 30%）,remained the same in 4 cases （8.70%）. Conclusion Retrograde irrigation is an effective method for searching the masal breakage, application of MMC in repair of broken canaliculus can prevent the junction＇s fibrosis and have good clinical results.
