Intraoperative bleeding during functional endoscopic sinus surgery (FESS) poses a challenge to both surgeon and anesthetist.

The primary aim of this study was to evaluate the effectiveness of local, intravenous and combined use of tranexamic acid (TA) in improving the surgical field quality during FESS.

We conducted a randomized controlled double-blinded prospective trial on 120 patients scheduled for elective FESS.

After induction of general anesthesia, patients were randomly and evenly assigned to one of four groups; IV TA, local TA, both IV and local TA, and placebo.

Surgical field was assessed using five-point Boezaart scale.

Total fentanyl and esmolol consumption, operative time, recovery time, and postoperative complications were recorded.
