To introduce modifications to Song's technique in the treatment of nasolacrimal occlusion by means of a polyuretane stent.
Thirty five polyuretane stents were placed under fluoroscopic guidance in 32 patients diagnosed with total and partial nasolacrimal occlusion.
Technical success rate was 90%. Sixteen right and nineteen left nasolacrimal systems were probed. The introduction of a guidewire through the lower punctum, the use of a Ritleng guide, a Crawford hook and ocular protectors are modifications of Song's procedure that may help in successfully performing this technique in a fast and easy way.
介绍对宋氏技术的改良，用于通过聚氨酯支架治疗鼻泪管阻塞。
在32例诊断为完全性和部分性鼻泪管阻塞的患者中，在荧光镜引导下放置了35个聚氨酯支架。
技术成功率为90%。探查了16个右侧和19个左侧鼻泪系统。经下泪点引入导丝、使用Ritleng导管、Crawford钩和眼部保护器是对宋氏手术的改良，可能有助于快速简便地成功实施该技术。
