The ethmoid arteries, comprising the anterior and posterior branches, are integral vascular structures that hold immense significance in the realm of sinus and skull base surgery. Originating from the third segment of the ophthalmic artery, these arteries traverse through the medial orbit before passing through the respective ethmoidal canals and entering the ethmoid air cells. Understanding the anatomical significance and clinical implications of the anterior and posterior ethmoid arteries is paramount in ensuring safe and effective management of sinus pathologies and associated complications. Accurate preoperative assessment, appropriate surgical techniques, and a thorough knowledge of these vascular structures are essential for optimizing patient outcomes and minimizing the risk of adverse events during surgical interventions.
