Purpose: To determine whether application of the anti-proliferation agent, mitomycin C (MMC), to the osteotomy site during dacryocystorhinostomy (DCR) surgery increases surgical success rates. Method: We conducted a comprehensive meta-analysis of randomised controlled clinical studies relating to the adjunctive use of MMC in primary and revision, as well as external (EX-DCR) and endonasal DCR (EN-DCR). Results: 15 studies met our inclusion criteria with a total of 850 DCR procedures. The mean concentration of MMC used was 0.3 mg/ml (range 0.02-0.75 mg/ml) and mean duration of application 18 min (range 2-30 min). MMC significantly reduced the failure rate of primary EX-DCR (risk ratio, RR, 0.51; 95% confidence interval, CI, 0.31-0.86) and revision EN-DCR (RR 0.43; 95% CI 0.21-0.89). The adjunctive use of MMC in primary EN-DCR, however, did not confer a significant reduction in failure rate compared with control (RR 0.94; 95% CI 0.44-2.04). We found a deficiency of evidence regarding the potential benefit of MMC in revision EX-DCR. Only two cases of adverse effects relating to the use of MMC were reported among the studies, both of which related to delayed wound healing. Conclusions: Application of MMC to the osteotomy site is a safe and effective way of increasing surgical success rate in primary EX-DCR and revision EN-DCR, but does not provide any significant benefit in primary EN-DCR. Further studies are required to evaluate the potential effect of MMC in revision EX-DCR.
