AIM:To evaluate the clinic value and the curative effects of silicone reverse-intubation in treating chronic dacryocystitis and nasolacrimal duct obstruction. METHODS:Totally 67 cases were studied retrospectively about postoperative curative effect from 3 months to 12 months, including 35 cases on silicone reverse-intubation and 32 cases on dacryocystorhinostomy. RESULTS：The cure rate of the group of the silicone reverse-intubation was 94%, of the dacryocystorhinostomy was 94%. The difference of two groups was not significant(P>0.05)，while the operative time of silicone reverse-intubation was significantly less than that of dacryocystorhinostomy(P<0.001). And there were no severe complications in silicone reverse-intubation group. CONCLUSION：The silicone reverse-intubation is a simple, convenient, economical and effective surgery which is suitable to popularize for treating chronic dacryocystitis and nasolacrimal duct obstruction.
