Tranexamic Acid in Rhinoplasty: Perioperative Bleeding, Edema and Ecchymosis

Tranexamic Acid in Rhinoplasty: Perioperative Bleeding, Edema and Ecchymosis

This study will be a prospective randomized study to evaluate the effect of tranexamic acid (TXA) use on intraoperative and postoperative outcomes among patients undergoing rhinoplasty by two Facial Plastic surgeons at Vanderbilt. Outcomes will include intra- and post-operative bleeding and postoperative bruising and swelling.

TXA is an antifibrinolytic agent that acts to decrease bleeding by stabilizing the fibrin matrix involved in the clotting cascade. The use of TXA, oral or intravenous, has been extensively used and described in the literature to prevent exsanguination in trauma and in various surgical procedures, as well as for heavy menstrual bleeding. It has been used in the perioperative period during various nasal and sinus surgery, and current research in rhinoplasty suggests that its use may decrease intraoperative bleeding and postoperative eye swelling and bruising.

Currently, IV TXA is used at this institution in some cases by some surgeons in the perioperative period in rhinoplasty surgery, though its used is not standardized and has not been studied. This study will randomize patients undergoing rhinoplasty, with consent, to receive TXA or placebo in the perioperative period. The investigators anticipate collecting 60-100 patients. Outcomes will include intraoperative bleeding, postoperative swelling and bruising (both subjective and based on blinded reviewer analysis of postoperative photographs).

TXA has been used in the perioperative period during various nasal and sinus surgery, and current research in rhinoplasty suggests that its use may decrease intraoperative bleeding and postoperative eye swelling and bruising. In these studies, TXA has been given in intravenous and/or oral form in 1-3 doses in the perioperative period, and there have been no serious adverse effects reported. IV TXA is also FDA approved for use at time of tooth extraction to decrease bleeding, and PO TXA is approved use during the menstrual cycle to decrease heavy menstrual bleeding. There are countless studies in the literature supporting use of both IV and PO TXA in trauma, orthopedic and spine surgery and neurosurgery, and it is widely used in clinical practice in these disciplines. It's use in rhinoplasty is growing, yet has not been studied in larger groups.
