方法：回顾性分析33例33眼慢性泪囊炎合并上泪道狭窄的患者资料，所有患者在进行外路泪囊鼻腔吻合术同时于上泪道留置硅胶泪道引流管，泪管留置时间为6mo。患者于术后1wk； 1，3，6，9mo复查，观察术眼泪道通畅、溢泪、溢脓等情况。

结果：术后1wk～6mo复查，冲洗泪道通畅率100%，均无溢泪 ； 术后6mo取出泪道置管，取管后3mo复查，32例(97%)冲洗泪道通畅，无溢泪； 1例(3%)冲洗阻力大，溢泪症状减轻。2例(6%)泪小点轻度撕裂，无其他并发症。

结论：泪道置管联合外路泪囊鼻腔吻合术能够有效治疗慢性泪囊炎合并上泪道狭窄。

METHODS: Thirty-three patients(33 eyes)with chronic dacryocystitis and upper lacrimal duct stenosis who underwent canalicular intubation combined ext-DCR were retrospective analyzed. The silicon tube was indwelt for 6mo. All cases were re-examined 1wk; 1, 3, 6, 9mo post-operation, flow of tears, pus excretion and lacrimal duct clearance were observed.

RESULTS: Clear lacrimal duct ratio was 100% in all cases during 1wk～6mo post-operation; Silicon tube was removed 6mo post-operation, 3mo after tube removal, rechecking reported 32 cases with clear lacrimal duct(97%)and 1 case with resistant duct(3%). Two cases(6%)with minor lacerations, no other complications were observed.

CONCLUSION: Canalicular intubation combined ext-DCR is an effective treatment for chronic dacryocystitis and upper lacrimal duct stenosis.
