BACKGROUND/OBJECTIVES: Recurrent stenosis and closure of neostium is considered a major factor for surgical failure in endoscopic dacryocystorhinostomy (Endo DCR). The main objective of this study is to evaluate the role of mitomycin c and silicone stent in maintaining the patency of the neostium. MATERIALS AND METHODS: Endo DCR were done in 180 patients. Group A included 40 patients where only mucosal flap was created, group B included 40 patients where silicon tube stents were used. Group C 40 included those in whom mitomycin c was applied to the neo ostium. Group D 40 included those in whom stenting along with mitomycin c was used. All the surgeries were done under general anaesthesia. RESULTS: In our study, 90% success in syringing patency was seen in group A, 85% success in syringing patency was seen in group B at 6 months of follow-up. 95% success was seen in group C. 100% success rate was seen in patients with mitomycin c application and stenting. Significant difference in success rate was seen group D. CONCLUSION: Significant difference in EDCR success rates were seen with the use of mitomycin c along with stenting in our study.
