The increasing use of endoscopic techniques for performance of functional intranasal and sinus surgery has allowed unrivalled visualization of nasal cavity and has awakened interest in transnasal approach to the nasolacrimal apparatus. The nasolacrimal apparatus being intimately related to lateral nasal wall may readily be approached using an endoscopic technique that minimizes functional interference with physiological action of the lacrimal pump. The study include 40 patients with 47 eyes affected were diagnosed as primary nasolacrimal sac or duct obstruction or chronic dacryocystitis. One patient with bilateral chronic dacryocystitis was randomized for bilateral external dacryocystorhinostomy. All 44 cases (100%0[21 cases (100%) in group I and 23 cases (100%) in group II] were patent on lacrimal syringing at the end of the 1^st dat and 1^st week. 19 cases (90.47%) in group I and 21 cases (91.3%) in group II were patent to lacrimal sac syringing at the end of 3^rd week, 3^rd month and 6^th month. Among the 2 failure cases in group I one patient undergone revision endoscopic DCR with stenting and was successful. Both the failed cases of primary endoscopic DCR underwent revision endoscopic DCR with stenting and were successful.
