Subcutaneous tranexamic acid in upper eyelid blepharoplasty: a prospective randomized pilot study.

Objective: Postoperative ecchymoses or hematomas can prolong healing from surgery, and a search for locally administered agents that decrease bleeding is warranted. The objective of this study is to evaluate whether preoperative subcutaneous injection of tranexamic acid (TXA) reduces intra- and postoperative bleeding or ecchymoses in skin-only upper eyelid blepharoplasty surgery.

Design: This is a prospective randomized, double-blind, controlled study.

Participants: We included 34 consecutive patients who were referred to an upper eyelid blepharoplasty surgery in our institution.

Methods: The patients were equally randomized to a preoperative local injection of lidocaine mixed with either TXA or normal saline. All patients stopped antiaggregates 1 week before surgery. All surgeries were performed by a single surgeon who was unaware of group assignment. Total surgical time, cumulative time of cautery use, blood loss, the surgeon's assessment of bleeding extent, pain level reported by the patient, periocular ecchymoses during the first postoperative week, and time for patient's return to normal daily activity were recorded.

Results: There was a trend toward smaller ecchymoses in the TXA group compared with the placebo group on the seventh day (p = 0.072). There were no group differences in total surgery time, cumulative cautery time, net blood weight in surgical pads, patient-reported pain level, surgeon's assessment of hemostasis, or periocular ecchymosis size on the first postoperative day.

Conclusions: Subcutaneous TXA was associated with similar intra- and postoperative hemorrhage in upper eyelid blepharoplasty compared with placebo. The effect of TXA in patients who did not stop antiaggregate use before surgery warrants further study.
