Epiphora due to nasolacrimal duct obstruction accounts for ∼3% of all general ophthalmology visits. Endoscopic dacryocystorhinostomy (DCR) has become accepted as a suitable treatment for patients with obstructions of the lacrimal system at the level of the sac or below it. Modification of endoscopic DCR is realized by using the overlapping flaps between the lacrimal sac and nasal mucosa with the creation of a wide bony ostium by drilling out the bony borders of the lacrimal sac.
