Study of Endonasal Endoscopic Dacryo-cystorhinostomy with Special Reference to Mitomycin-C.

The aim of this study was to evaluate long-term results in patients with nasolacrimal duct obstruction treated with intranasal endoscopic dacryo-cystorhinostomy (DCR) with intraoperative topical application of mitomycin-C. The procedure was carried out in 34 subjects (41eyes). Patients with post-saccal stenosis were divided into two groups, 21 patients were treated with intranasal endoscopic dacryo-cystorhinostomy with intraoperative application of Mitomycin-C (MMC) and the other 20 cases underwent procedure only without Mitomycin-C.
