Abstract
OBJECTIVE
Many studies have evaluated the effectiveness of topical intraoperative mitomycin (MCC) usage in a wide range of Otolaryngologic procedures with variable conclusions on effectiveness. This systematic review aims to provide a qualitative estimation of mitomycin C's treatment effectiveness in maintaining or preventing stenosis after surgical interventions.
DESIGN AND MAIN OUTCOME MEASURES
Following the PRISMA guideline, a comprehensive systematic search of MEDLINE, EMBASE, and CINAHL databases was performed including hand-searching and cross-reference checking. The search was limited to humans, sample size greater than two, and study designs including a comparative arm.
RESULTS
571 unique abstracts and 109 full articles were reviewed. 77 studies were included in the final analysis. The available evidence ranged from case series to randomized control studies. Meta-analysis was deemed inappropriate due to heterogeneity of study design. 38 studies assessed the effective of MCC in dacryocystorhinostomy, which is reported in a separate meta-analysis. All other studies were categorized into otolaryngologic site and pathology including: choanal atresia (n=5), endoscopic sinus surgery (n=12), airway procedures (n=9), esophageal procedures (n=8), and other (n=2).
CONCLUSIONS
The published literature on the effectiveness of MMC was mixed, but suggested topical MMC improved surgical outcomes in many Otolaryngologic procedures compared to controls. This was the first review to assemble literature on MMC usage for different surgical procedures. Comprehensive interpretation of the data was limited due to heterogeneity in primary outcome, procedure type, and study quality. High quality prospective and randomized controlled studies are required to further confirm the positive effect of MMC use on surgical outcomes.
