目的:总结逆行植入泪道扩张引流管治疗鼻泪管阻塞和慢性泪囊炎的并发症及解决方法。方法:对临床诊断为鼻泪管阻塞和慢性泪囊炎的110例113眼患者,逆行植入泪道扩张引流管治疗,观察术后至拔管4mo内出现的并发症。结果:拔管困难26眼（23.0%）,鼻腔残端隐藏5眼（4.4%）,引流管脱落3眼（2.7%）,泪道支撑管刺破泪阜1眼（占B型管5.9%）,泪小管狭窄7眼（6.2%）,鼻泪道冲洗返流5眼（4.4%）。结论:泪道扩张引流管植入是治疗鼻泪管阻塞或慢性泪囊炎的一种有效、安全的治疗方法,只要医生细心、认真、温和地操作,会避免很多并发症的发生,提高治愈率。

AIM:To summarize the complications and solutions of retrograde lacrimal dilated drainage tube implantation for the treatment of nasolacrimal duct obstruction and chronic dacryocystitis.METHODS:Totally 110 cases (113 eyes) diagnosed with nasolacrimal duct obstruction or chronic dacryocystitis were treated with retrograde lacrimal dilated drainage tube implantation. Complications from postoperation to removing the drainage tubes 4 months were observed.RESULTS:There were 26 eyes（23.0%）with difficulty in removing tubes, 5 eyes（4.4%）with drainage tube invisible in nasal cavity, 3 eyes（2.7%）with drainage tube exfoliated, 1 eye（5.9% of B tube）with lacrimal caruncle punctured, 7 eyes （6.2%）with lacrimal canaliculus stenosis, 5 eyes （4.4%）with lacrimal passage reflux.CONCLUSION:The retrograde lacrimal dilated drainage tube implantation is effective and safe for the treatment of nasolacrimal duct obstruction and chronic dacryocystitis. Only the physician operates seriously, carefully and softly, it will reduce many complications and improve the cure rate. 
