经泪囊切开逆行探通泪小管断裂吻合术

目的 评价泪小管断裂时经泪囊切开，逆行探查泪小管鼻侧断端吻合手术的疗效。方法 外伤性下泪小管断裂93例(93眼)，上下泪小管均断裂11例(11眼)，先采用注气或注液法、直视法、试探法、探通法等均不奏效时，即改为泪囊切开法，经泪囊切开逆行探查寻找泪小管鼻侧断端，进而行泪小管吻合术。结果 104例均经3月至5年以上的随访，自觉不流泪，冲洗泪道通畅者96例(92．30％)；自觉轻微流泪，冲洗泪道通而不畅者6例(5．77％)；流泪，冲洗泪道不通者2例(1．93％)。结论 泪囊切开法找到泪小管断端准确率高。

Retrograde intubation via lacrimal sac to seek the lacerted ends and anastomosis in lacrimal canaliculi laceration

Objective To evalute the effect of retrograde intubation via lacrimal sac to seek the lacerted ends and anastomosis in lacrimal canaliculi division.Methods 104 inpatients (104 eyes) with the canalicular laceration were treated by retrograde intubation through an icision over lacrimal sac after failed by routine methods, the nasal end is found and anastomosis is opened.The cases were followed-up and statistically analysed postoperativeely.Results All the 104 cases were followed up from 3 months to 5 year.96 cases(92.30%)obtained anatomical success.Conclusion Retrograde intubation via lacrimal sac can easily found the lacerted ends,and then effectively achieve anastomosis.
