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.
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.
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.
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.
本研究的目的是在冠状位CT（CCT）扫描上识别可识别的标志，用于定位筛前动脉和筛后动脉，它们是筛窦内重要的解剖结构和手术标志。
评估了四组塑化尸体标本和80例CCT检查，以识别确定筛前动脉和筛后动脉在筛窦内走行的解剖标志。
以下解剖标志：眶内侧壁的压痕、上斜肌与眶内侧直肌的关系以及筛骨外侧隐窝壁变薄，被证明是用于定位筛前动脉和筛后动脉的有用的CCT标志。
本研究结果表明，熟悉常规CCT图像上的上述标志有助于在筛前动脉和筛后动脉进入筛窦时对其进行定位。
