The Effect of Peroperative Steroid Therapy on the Surgical Field during Endoscopic Sinus Surgery

Background: Bloodless surgical field during functional endoscopic sinus surgery is very important not only to make the surgery more easy but also to decrease the incidence of complication.The aim of the present study was to determine is the short term preoperative corticosteroid oral therapy have effect on the operative field in functional endoscopic sinus surgery or not.Methods: Functional endoscopic sinus surgery was performed in 24 patients with extensive polypoid rhinosinusitis. Patients were divided into two groups steroid group Group 1 (received 45mg of prednisone daily for 6 consecutive days before operation) and control group Group 2. Total blood loss and visualization of the surgical procedure were compared in the 2 groups.Results: The visual conditions of the surgical field improved significantly, however the total blood loss was only slightly less in the steroid group.Conclusions: Short term preoperative steroid therapy before functional endoscopic sinus surgery in patients with severe polyposis significantly improved the operative field and shortened the time of surgery.
