Nasal Endoscopic Dacryocystorhinostomy The Nizamabad experience.

Chronic dacryocystitis results very often from obstruction to the nasolacrimal duct. It manifests as epiphora or watering of the eyes. The lacrimal sac gets expanded and also the wall of the sac gets thickened as a result of collection of mucopus due to obstruction of the nasolacrimal duct. Treatment of chronic dacryocystitis is by a surgical approach which consists of making an opening between the lacrimal sac and the nasal cavity above the obstruction. This operation is called dacryocystorhinostomy which can be done by external approach or nasal endoscopic approach. The intranasal or nasal endoscopic approach is the more functional route of surgery because it preserves the lacrimal apparatus as near normal as possible. Hence this surgery is being advocated as the first line of treatment for epiphora of chronic dacryocystitis. Experience of nasal endoscopic dacryocystorhinostomy done at Government Medical College, Government General Hospital, Nizamabad, Telangana is being reported with comparison of results published in literature.
