Safety and efficacy of adjunctive intranasal mitomycin C and triamcinolone in endonasal endoscopic dacryocystorhinostomy

One of the common causes of failure in dacryocystorhinostomy for nasolacrimal duct obstruction (NLDO) is mucosal scarring and fibrosis around the ostium. Steroid and mitomycin C (MMC) can potentially reduce scarring by their action on the inflammatory and proliferative phase of wound healing, respectively. The purpose of this study is to evaluate the safety and efficacy of combined usage of adjunctive MMC and intranasal triamcinolone (TA) in...
