To evaluate the clinical utility of plastic stents in treatment of complete obstruction of the nasolacrimal duct.
Nineteen plastic stents were successfully placed under fluoroscopic guidance in 16 consecutive patients with epiphora due to complete obstruction of the nasolacrimal duct. After balloon dilation of the obstructed area, the stents were placed in the lacrimal system with the head portion lying in the dilated lacrimal sac and the body in the nasolacrimal duct and projecting into the inferior meatus of the nasal cavity.
Complete resolution of epiphora was accomplished in 15 (79%) of 19 eyes and partial resolution in the remaining four (21%) eyes.
These preliminary results with use of plastic nasolacrimal stents are encouraging.
评估塑料支架在治疗鼻泪管完全阻塞中的临床应用价值。
在透视引导下，为16例因鼻泪管完全阻塞而溢泪的连续患者成功置入19个塑料支架。在对阻塞区域进行球囊扩张后，将支架置入泪道系统，头部位于扩张的泪囊中，主体位于鼻泪管并伸入鼻腔下鼻道。
19眼中有15眼（79%）溢泪完全缓解，其余4眼（21%）部分缓解。
使用塑料鼻泪管支架的这些初步结果令人鼓舞。
