目的:探讨人工鼻泪管支架植入术的手术技巧，评价其疗效。 方法：自2009/2011年选择42例42眼鼻泪管阻塞患者，在局部麻醉下，经鼻腔逆行植入永久性人工鼻泪管，术中使用带侧孔探针代替原包装中的直孔探针，通过调节探针侧孔的位置，使引导丝下端自下鼻道自行脱出，术后随访6mo，观察其临床疗效。 结果：患者42例42眼成功植入人工鼻泪管，手术植入成功率100%。术后6mo进行随访，有效率100%。 结论：改良永久性人工鼻泪管植入术治疗慢性泪囊炎与鼻泪道阻塞操作简单安全，疗效确切，有推广价值。

AIM:To explore the surgical skills of artificial nasolacrimal duct stent implantation, and to evaluate its effect. METHODS:From 2009 to 2011, 42 cases (42 eyes) with nasolacrimal duct obstruction were chosen to have the operation of permanent artificial nasolacrimal duct stent placement, which was through nasal cavity under local anesthesia. In the operation, original straight hole probe was replaced with side hole probe, to make the guide wire out automatically through adjusting the position of side hole. The clinical effect to each case was followed up for six months. RESULTS:The artificial nasolacrimal duct stent was successfully placed for 42 cases, the efficiency was one hundred percent based on six months follow-up after implanting surgery. CONCLUSION:The operation of artificial nasolacrimal duct stent implantation used for the treatment of chronic dacryocystitis and nasolacrimal duct obstruction is simple and safe, and its curative effect is sure, so this kind of operation is worth being popularized widely.
