ABSTRACT: This study was done in 92 patients presenting to the department of ENT, Shanthiram Medical College, Nandyal, Andhra Pradesh with nasolacrimal duct obstruction. Our technique consists of mucosal flap elevation, complete exposure of sac with chisel and a large marsupialization of sac. We have achieved 85% success rate using this technique with follow up period of 6 months to 4 years. This technique is simple, cost effective and easy to learn and teach. In our study majority of failures were cases having a small and atrophic sac. We recommend preoperative dacryocystography to identify cases with healthy sac which can help increase success rate of this technique.
