方法：回顾性分析51例53眼慢性泪囊炎患者鼻腔内窥镜下手术治疗效果，其中经鼻内镜下行鼻泪管逆行插管31例32眼，采用鼻腔泪囊造孔术治疗20例21眼，随访6mo。

结果：鼻内镜下鼻泪管逆行插管术：治愈15眼，好转12眼，无效5眼，治愈率47%，有效率84%； 鼻内镜下鼻腔泪囊造孔术：治愈14眼，好转5眼，无效2眼，治愈率67%，有效率90%； 两组治愈率、有效率比较差异无统计学意义。

结论：鼻内镜下改良鼻泪管逆行插管和鼻腔泪囊造孔术均有微创、愈合快、疗效好等优点，其疗效相近，鼻内镜下逆行插管术更简便易行、价格低、容易推广。

METHODS: A retrospective analysis of 51 cases( 53 eyes)of chronicdacryocystitis patients with nasal endoscopic operation. Intubation group had 31 cases 32 eyes, the dacryocystorhinostomy group had 20 cases 21 eyes, the follow-up was half a year.

RESULTS:Endoscopic nasolacrimal tube retrograde intubation: 15 eyes were cured, 12 improved, invalid 5, the cure rate was 47%, with an efficiency of 84%; endoscopic dacryocystorhinostomy: cured 14, improved 5, invalid 2, the cure rate was 67%, with an efficiency of 90%; there was no obvious difference.

CONCLUSION:Endoscopic modified nasolacrimal duct retrograde intubation and endoscopic dacryocystorhinostomy are minimally invasive, rapid healing, good effect, its efficacy is similar, endoscopic retrograde intubation is simple, low price, easy popularization.
