AIM:To study the effects of endoscopic-assisted rhinodacryocystostomy.METHODS:Rhinodacryocystostomy with the aid of endoscope was operated in 36 cases 42 eyes.If concurrently suffering from nasal diseases,patients were also treated with endoscopic-assisted nasal surgery.The patency conditions of lacrimal passages were observed after the operations.RESULTS:Through post-surgery irrigation for six months,lacrimal passages showed patency in 38 eyes(90%),poor patency in 36 cases 42 eyes and obstruction in 2 eyes (5%), and were still blocked in 2 eyes(5%).CONCLUSION:The curative effect of endoscopic-assisted rhinodacryocystostomy is accurate and minimally invasive, facially scar-free.
