Effects of Aspirin on Postoperative Bruising and Bleeding Complications in Upper Eyelid Surgery

Purpose: We evaluated the effects of aspirin versus placebo in patients undergoing upper eyelid blepharoplasty and/or levator advancement or plication blepharoptosis repair in this randomized, prospective study. Methods: Patients who presented between October 2017 and April 2019 requiring blepharoptosis repair and/or upper eyelid blepharoplasty who were taking 81 mg aspirin were randomized to receive 1 week of aspirin tablets or 1 week of placebo tablets prior to surgery. Postoperative complications, such as bleeding, hematoma, or hemorrhage, were noted as well as perioperative thromboembolic complications. Photos were obtained at the patient's first postoperative visit and later judged on bruising severity. The 2 groups were subsequently compared. Results: A total of 48 patients and 89 eyelids were evaluated in this study. Fifty-two eyelids were included in the aspirin group and 37 eyelids were included in the placebo group. There was no statistically significant difference in bruising rating between groups. There was no statistically significant difference in the number of patients who experienced mild postoperative bleeding. No patients experienced vision loss. No patients experienced a thromboembolic event. There were no patients who experienced hemorrhage, hematoma, or retrobulbar hemorrhage. Conclusions: Continuation of aspirin does not appear to effect outcomes with respect to postoperative bruising in patients undergoing upper eyelid blepharoplasty or blepharoptosis repair. The study was not powered to determine statistical significance with regard to bleeding complications and would require a significantly higher sample size. We suggest changing the current guidelines to recommend routine continuation of low dose 81 mg aspirin before upper eyelid surgery.
