A Simple Clinical Application for Locating the Anterior Ethmoidal Artery Using the Anterior Ethmoidal Foramen and the Anterior Nasal Spine.

ABSTRACT:

Purpose

The anatomy and variations of the anterior ethmoidal artery (AEA) are clinically relevant. The anterior ethmoidal foramen (AEF) can be used to locate the initial site of the AEA, and the anterior nasal spine (ANS) is a constant bony marker in the anterior nasal atrium. However, there is no relevant research on AEF and ANS targeting the AEA. Hence, this study aimed to accurately locate the AEA through AEF and ANS using computed tomography.

Methods

A total of 120 (240 sides) sinus computed tomography scans were retrospectively selected and studied. The AEA was classified into grades I, Ⅱ, and Ⅲ group based on the relationship between the AEA and the skull base. The distance between AEF and ANS and the angle between AEF-ANS and the axial plane were measured.
