方法：对67例67眼内眦角或眼睑裂伤致下泪小管断裂即时吻合术中，无论伤前有无溢泪环形置管的可行性，置管保留时间，并发症及拔管后冲洗6mo以上情况追踪研究。

结果：患者67例67眼全部成功置管，有62例吻合成功，3例拔管后泪道狭窄，2例拔管后冲洗不通，经泪道YAG激光处理后再通。

结论：外伤致泪小管断裂即时吻合术中环形泪道置管法，无论伤前有无溢泪，均能成功置管，且因置管保留在鼻腔内，可较长时间保留，不影响日常生活、工作，保证了在无牵拉的情况下泪小管断端的修复，减少了并发症，疗效良好。

METHODS: In 67 cases(67 eyes)of inner canthal angle or eyelid laceration of canaliculus anastomosis, the catheterization feasibility, complications, the retention time of catheter as well as extubation more than half a year's presented were studied.

RESULTS: In the 67 cases, there were 62 cases underwent successful anastomosis, lachrymal in 3 cases was narrow after extubation, 2 cases were impassability rinsing, lachrymal was unobstructed after YAG laser treatment.

CONCLUSION: Injury canaliculus ring immediately before intubation in the law, whether it has epiphora or not, can successfully catheter, and because the catheter retained in the nasal cavity, which can be maintained for a longer time, and does not affect the daily life, work, ensure no pull in repair under the condition of the broken end of the canaliculus, less complications, efficacy.
