Abstract

Abstract Endoscopic sphenopalatine artery ligation has become the standard surgical therapy for posterior epistaxis refractory to nasal packing. A thorough understanding of the arterial blood supply to the nasal cavity is necessary for optimal surgical results. The crista ethmoidalis is the key landmark for identification of the sphenopalatine foramen. The sphenopalatine artery branches may be controlled with hemoclips, bipolar cautery, or both. Recent cost-benefit and cost-utility analyses have suggested endoscopic sphenopalatine artery ligation may be considered earlier in the epistaxis treatment algorithm.
