Intraoperative variations of the sphenopalatine artery between epistaxis and non-epistaxis cases: a comparative endoscopic analysis

Abstract Background Severe epistaxis is one of the most common emergencies in rhinology practices. The commonly used endoscopic cauterization sphenopalatine artery (SPA), alone or with anterior ethmoidal (AEA), has a high success rate for controlling severe epistaxis. current study was conducted to evaluate intra-operative variations SPA between and non-epistaxis cases. Forty consecutive patients who underwent exploration were included study. They distributed into two groups depending upon indication exploration; group (group A, n =25 patients, =26 sides) B, =15 sides). Criteria main compared regarding four parameters; arterial diameter, adherence mucosa lower part basal lamella, nerve bundle, crista ethmoidalis erosion. Results A significant difference found diameter groups; mean 4.2±0.64 mm 3.2±0.35 respectively ( p = 0.043). Moreover, highly tendency observed lamella bundle group; ≤0.01). Conclusion These data clearly signify importance intraoperative identification criteria during surgical management may help altering decision solely concomitant SPA/AEA cauterization.
