Neo-ostium cicatrization and closure is considered a major factor for surgical failure in endoscopic dacryocystorhinostomy (EnDCR). Wide neo-ostium, mucosal flaps, sac marsupialization with primary healing and silicone tube stent improves surgical outcomes of EnDCR.

Materials and methods

EnDCR were done in 238 patients. Group A included 172 patients where no stents were used and group B included 66 patients where silicon tube stents were used. All the surgeries were done under general anesthesia.


In our study, 89.53% success in syringing patency was seen in group A, 89.39% success in syringing patency was seen in group B at 6 months of follow-up. No significant difference in success rate were seen in the two study groups.


No significant difference in EnDCR success rates were seen with the use of stents in our study. So stenting probing and dilatation are not advocated routinely in all cases and a wide neo-ostium with mucosal flaps and primary healing is the secret to success.
