目的：比较鼻腔泪囊吻合术(EDCR)及鼻内镜下鼻腔泪囊造孔术(IEDCR)联合泪道置管的疗效，探讨治疗泪囊炎的最佳手术方法。

方法：随机将门诊确诊的慢性泪囊炎患者37例37眼分为两组，分别采用上述两种手术方法治疗，术后随访6～12mo观察手术疗效。

结果：IEDCR组17眼，有效16眼，好转1眼，总有效率为94%； EDCR组20眼，有效18例，好转2眼，总有效率为90%。EDCR组与IEDCR组之间有效率无显著性差异(P>0.05)。IEDCR组术后反应轻，面部无瘢痕，恢复较快。EDCR组术后反应重，面部留有瘢痕，恢复较慢。

结论：EDCR和IEDCR均是治疗慢性泪囊炎的可靠方法，但IEDCR微创术后反应及疗效好，值得推广应用。

AIM: To investigate the effects on patients with chronic dacryocystitis treated with two methods: external dacryocystorhinostomy(EDCR)and intranasal endoscopic dacryocystorhinostomy(IEDCR)combined with intubation of lacrimal ducts, and to explore the best operation method.

METHODS: Totally 37 cases(37 eyes)were randomly divided into two groups, using EDCR and IEDCR respectively, postoperative follow-up lasted 6～12mo.

RESULTS: The success rate of IEDCR group and EDCR group were 94%(17 eyes)and 90%(20 eyes)respectively. There was no significant difference between EDCR group and IEDCR group(P>0.05). There were Slighter postoperative reaction, no postoperative scar, faster postoperative recovery in IEDCR group than those in EDCR group.

CONCLUSION: EDCR and IEDCR were effective methods. Especially IEDCR is minimal invasive technique and worthy of promotion and application.
