Tissue Sealants for Facial Rhytidectomy: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Abstract

Background: The aging face can be surgically treated with a face-lift (rhytidectomy); however, bleeding and hematoma are complications that surgeons seek to prevent. Objective: To compare the drainage volume and rate of hematoma in studies of rhytidectomy among those having tissue sealants and those without. Methods: This systematic review and meta-analysis was prospectively registered in PROSPERO (CRD42022325404). We included randomized controlled trials (RCTs) that the enrolled participants undergoing rhytidectomy and used tissue sealants as the intervention. We calculated the mean and standard deviation for the drainage volume; risk ratios (RRs) were used for hematoma incidents. Results: Seven RCTs were included. The drainage volume was significantly lower in the tissue sealant group than in the control group (mean difference [MD]: -11.01, confidence interval [95% CI]: -18.39 to -3.63, p < 0.00001). As for hematomas, the incidence was also lower in the tissue sealant group (RR: 0.29, 95% CI: 0.08-0.99, p = 0.05). Conclusion: This study suggests that tissue sealants can be effective in reducing drainage volume and hematoma in face-lift; however, autologous and homologous tissue sealants can be further compared in future RCTs.
