人工鼻泪管植入治疗鼻泪管阻塞

Artificial nasolacrimal duct for nasolacrimal duct obstruction

目的探讨人工鼻泪管植入术的手术技巧,评价其疗效。方法对32例(32只眼)鼻泪管阻塞行人工鼻泪管植入术,经逆行扩张鼻泪道后植入特制的人工鼻泪管,均于术前行泪道造影检查。结果32只眼30只眼成功植入了人工鼻泪管,手术植入成功率为93.8%。术后6月随访有效率为100%。结论人工鼻泪管植入术治疗鼻泪管阻塞操作简单,安全性好,有效率高。

Objective To observe the intraoperative techniques of interventional procedure using an artificial nasolacrimal duct and evaluate the effectiveness. Methods 32 cases （32 eyes） of nasolacrimal duct obstruction underwent artificial nasolacrimal duct. The nasolacrimal duct was dilated and the stent was retrogradely placed. Dacryocystography was performed before the operation. Results Artificial nasolacrimal duct placement was technically successful in 30 eyes and the technical success rate was 93.8% （30/32）. The response rate was 100% （30/30） six months after operation. Conclusion Interventional artificial nasolacrimal duct placement is a safe, simple and effective method for the treatment of nasolacrimal duct obstruction.
