Increased lacrimation (epiphora) is a troublesome symptom for both patients and doctors; Even though various causes produce epiphora dacryocystitis is the commonest pathological cause for epiphora. Chronic dacryocystitis is treated with dacryocystorhinostomy. The surgical procedure of diversion of lacrimal flow within nasal cavity through an artificial fistula made at the level of lacrimal sac is called dacryocystorhinostomy. The surgery has been performed for the post 100 years. In this study 50 patients were evaluated and found to have nasolacrimal duct obstruction. All of them underwent Endonasal Endoscopic dacryocystorhinostomy. Of the 50 patients who underwent the study the following conclusions are achieved. a) Disease is common in middle age. More common in 30 – 40 years age group. b) Females are affected more than males. 4: 1 ratio c) Commonest presenting symptom is Epiphora. d) Commonest sign of disease is regurgitation of purulent material on compression of sac. e) Correction of high septal deviation improve the results of the surgery. f) Treating the concurrent nasal disease appropriately prior to the lacrimal surgery improves the outcome. g) Bilateral diseases could be managed simultaneously without much problem. h) Common difficulties encountered were narrow nasal cavity, thick frontal process of maxilla and bleeding during elevation of flap. Common postoperative problems were granulation and synechiae at the neoostium. j) Nearly 95% patient had complete relief of symptoms. k) Interestingly revision DCR had 100% complete relief of symptoms. This may be due to small sample size. The success rate achieved by endonasal dacryocystorhinostomy was as high as that of external dacryocystorhinostomy without the disadvantages of external DCR.
