方法：我院2007-03/2012-06对18例18眼传统外路泪囊鼻腔吻合术或鼻内镜下泪囊鼻腔造孔术后仍有溢泪或伴溢脓的患者行鼻内窥镜下泪囊鼻腔造孔术，术中针对不同再堵塞因素分别给予扩大骨孔，分离粘连部位，清除机化凝血泪囊鼻腔块、瘢痕、肉芽等病变组织，留置泪道插管，术后应用鼻用激素并定期行鼻内镜检查。

结果：随访6mo～1a，15例治愈，2例有效，1例无效，治愈率83.3%，总有效率94.4%。

结论：鼻内窥镜下泪囊鼻腔造孔术治疗复发性泪囊炎，手术损伤小，操作简便，成功率高，值得临床推广。

METHODS: Totally 18 cases(18 eyes)of recurrent dacryocystitis were operated with dacryocystorhinostomy by nasal endoscopy from March 2007 to June 2012. During the dacryocystorhinostomy, the hole in the bone was expanded, and adhesion sites were separated. Blood clot, scar, granulation, and other lesions were cleared up. Nasal steroids were used after operation.

RESULTS: The patients were followed up for 6-12 months after operation. Fifteen cases(83.3%)were cured, 2 cases(11.1%)were improved, 1 case were failed. The total effective was 94.4%.

CONCLUSION: Dacryocystorhinostomy appears to be an effective and safe filtering procedure in recurrent dacryocystitis with the advantage of having fewer complications. It is worthy of clinical application.
