Clinical Applications of Tranexamic Acid in Plastic and Reconstructive Surgery.

[BACKGROUND] Tranexamic acid (TXA) has gained increasing recognition as a valuable pharmacologic agent within plastic surgery. This study reviews the scientific evidence regarding the use of TXA in the full range of plastic and reconstructive surgery to provide clinical recommendations for safe and effective use in various plastic surgical procedures.

[METHODS] A systematic review and meta-analysis were conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. An established appraisal process was used to rate the quality of articles (Grading of Recommendations Assessment, Development, and Evaluation methodology).

[RESULTS] Forty-five studies describing the use of TXA in plastic surgery were included. There is moderate-certainty evidence to support the use of intravenous administration of TXA in craniofacial surgery procedures to reduce blood loss and transfusion requirements. There is high-certainty evidence to support the use of TXA in cosmetic surgery and intravenous administration in rhinoplasty procedures to reduce blood loss. Further high-level studies are needed to determine TXA's effects on hematoma rates in face-lift surgery and breast-related procedures. There is moderate-certainty evidence to support the use of TXA in burn care. Further studies are required to provide quantitative conclusions on the effects of TXA administration in microsurgery.

[CONCLUSIONS] This is the largest study to date on the use of TXA in plastic surgery and the first to provide clinical recommendations. The literature highlights TXA's promising role in the fields of craniofacial surgery, cosmetic surgery, and burn care. Standardized, objective measurements are required to provide quantitative conclusions regarding TXA's effects on ecchymoses and edema in cosmetic surgery procedures.
