Abstract
To assess the efficacy of topical silicone gel in the management of scars, we conducted this meta-analysis. The systematic search was performed on PubMed, Web of Science and Embase, and six randomised controlled trials with a total of 375 patients were involved. The outcome data of Vancouver Scar Scale were extracted from the studies and their effect sizes were calculated using Review Manager 5.3. As a result, topical silicone gel significantly reduced pigmentation, height, and pliability scores postoperatively compared with placebos or no treatment (Pigmentation: standard mean difference [SMD] = -0.55 [-0.83 to -0.26], P = .0002; Height: SMD = -0.73 [-1.02 to -0.44], P < .00001; Pliability: SMD = -0.49 [-0.95 to -0.03], P = .04). Topical silicone gel and silicone gel sheet were comparably effective (P > .05). The performance of topical silicone gel and other non-silicone topical treatment was also similar (P > .05). In summary, topical silicone gel was effective in post-operative scar prevention.
