Endoscopic and Open Anterior/Posterior Ethmoid Artery Ligation
Abstract
Abstract This chapter explains how to reliably perform an endoscopic endonasal ligation of the anterior ethmoidal artery (AEA) and posterior ethmoidal artery (PEA). These are major vessels supplying the ethmoid sinus, septum, and anterior skull base. Control of these vessels is a key step in performing extended sinus and skull base procedures.
