To describe the placement of a nasolacrimal polyurethane stent with a new introducer set and hook.
The authors designed a soft polyurethane stent, an introducer that does not require balloon dilation, and a hook that can remove a ball-tipped guide wire from the inferior nasal meatus under fluoroscopic guidance. The stent was placed in 51 lacrimal systems in 44 outpatients who had complete obstruction of the lacrimal sac or nasolacrimal duct.
Stent placement was technically successful and well tolerated in 50 of 51 nasolacrimal systems. The procedure lasted an average of 16 minutes (range, 10-33 minutes). After stent placement, 47 of 50 eyes showed complete resolution of epiphora, and the other three showed partial resolution. During follow-up, no stents migrated, and one stent became blocked. The stent was reopened by means of forceful irrigation of saline solution through the superior punctum.
Placing a polyurethane nasolacrimal stent by use of the new introducer and hook simplifies the technique, shortens operating time, reduces cost, and makes the procedure well tolerated by patients.
描述使用一种新型导入器套件和钩子放置鼻泪管聚氨酯支架的方法。
作者设计了一种柔软的聚氨酯支架、一种无需球囊扩张的导入器以及一种可在荧光镜引导下从下鼻道取出球头导丝的钩子。该支架被放置在44例门诊患者的51个泪道系统中，这些患者存在泪囊或鼻泪管完全阻塞的情况。
在51个鼻泪管系统中的50个中，支架放置在技术上成功且耐受性良好。手术平均持续16分钟（范围为10 - 33分钟）。支架放置后，50只眼中的47只溢泪症状完全缓解，另外三只部分缓解。在随访期间，没有支架移位，且有一个支架堵塞。通过从上泪点强力冲洗生理盐水使该支架重新通畅。
使用新型导入器和钩子放置聚氨酯鼻泪管支架简化了技术，缩短了手术时间，降低了成本，并使该手术患者耐受性良好。
