. Patients with nasal polyposis are predisposed to diffuse intraoperative bleeding, that could highly impair surgical field visualization. The absence of a universal technique of improving surgical field visualization became a reason for searching the specific hemostatic methods. Objective : to evaluate the efficiency of sphenopalatine artery and/or its branches coagulation as a method of hemostasis in endoscopic surgery for nasal polyposis and to describe the surgical anatomy of sphenopalatine artery. Materials and methods . Endoscopic coagulation of sphenopalatine artery and/or its branches was performed among 30 patients with nasal polyposis. Surgical field visualization was graded by Boezaart and Wormald scales before and after coagulation. Results and discussion . Intraoperative attempts to achieve the hemostasis using warm (490С) saline irrigation and then application of xylometazoline (0.1%-10ml) and lidocaine (10%-4ml) were ineffective among 28 patients with initial grade 8 and among 2 patients with grade 9 according to Wormald scale. Sphenopalatine artery and/or its branches coagulation was effectively performed in these patients, obtaining the hemostasis in 100% of cases (р < 0,001). The initial surgical field grade improved to grade 5 by Wormald scale in 9 patients (30%), to grade 6 in 17 patients (56,7%) and to grade 7 in 4 patients (13,3%). Only one artery (trunk of sphenopalatine artery) was observed in 18 patients (60%), crossing the sphenopalatine foramen, and 2 arteries (posterior septal artery and posterior lateral nasal artery) – in 12 patients (40%). Endoscopic examination revealed no signs of mucosal atrophy in postoperative period. Conclusion : The appropriate choice of hemostatic technique depends on grades of surgical field visualization. If there is a grade 8–9 by Wormald scale, endoscopic coagulation of sphenopalatine artery and/or its branches is an effective and safe method to improve surgical field visualization.
