OBJECTIVE: The aim of this study was to identify recognizable landmarks on coronal CT (CCT) scans for the localization of the anterior and posterior ethmoid arteries, which are important anatomic structures and surgical landmarks within the ethmoid sinuses.
MATERIALS AND METHODS: Four series of plastinated cadaver specimens and 80 CCT examinations were evaluated to identify the anatomical landmarks that define the course of the anterior and posterior ethmoid arteries within the ethmoid sinuses.
RESULTS: The following anatomic landmarks: the indentations into the medial orbital wall, the relationship between the superior oblique and medial rectus orbital muscles, and the lateral ethmoid fovea wall thinning proved to be useful CCT landmarks for the localization of the anterior and posterior ethmoid arteries.
CONCLUSION: The results of this study suggest that familiarity with the above-mentioned landmarks on routine CCT images facilitates the localization of the anterior and posterior ethmoid arteries as they enter the ethmoid sinus.
