Posterior Ethmoidal Artery: Surgical Anatomy and Variations
View through CrossRef
The posterior ethmoidal artery is a collateral of the ophthalmic artery and participates in the vascularization of the nasal cavities. It is an important landmark in endonasal surgery with complex orbital contents relationships. We recognize many anatomical and functional varieties. This chapter proposes to present a classic descriptive anatomical study but also a modern radiological and endoscopic study of the posterior ethmoidal artery. It also proposes to present a description of some pathologies associated with this artery, particulary posterior epistaxis and other vascular disorders. The surgical procedur to access to posterior ethmoidal artery,external or endoscopic approach of the posterior ethmoidal artery will be described.
