In order to study the relation of ethmoid labyrinth to the adjacent structures, continuous axial CT scan of the ethmoid labyrinth was performed on 9 normal subjects. Meanwhile, coronal and axial CT scans of ethmoid labyrinth were obtained in 20 normal subjects. On an average, 22 scan sections were done on each subject. The relation of ethmoid labyrinth to adjacent structures was observed and the remarkable intersubject variations in this anatomic area were noted. The relation of posterior ethmoid cells or sphenoid sinus to the optic canal, and the relation of internal carotid artery to the sphenoid sinus were clearly demonstrated on axial scans. The detailed anatomic structure of the ostiomeatal complex and the anatomic relation of ethmoid labyrinth to orbit and anterior skull base were revealed by coronal CT scans. CT scan of the paranasal sinuses was of great importance in clinical practice for the purpose of etiological analysis of sinusitis, design of endoscopic sinus surgery and prevention of complication.
为研究筛迷路与相邻结构的关系，对9名正常受试者进行了筛迷路的连续轴位CT扫描。同时，对20名正常受试者进行了筛迷路的冠状位和轴位CT扫描。平均每名受试者进行了22个扫描层面。观察了筛迷路与相邻结构的关系，并注意到该解剖区域存在明显的个体间差异。轴位扫描清晰显示了后筛窦或蝶窦与视神经管的关系，以及颈内动脉与蝶窦的关系。冠状位CT扫描揭示了窦口鼻道复合体的详细解剖结构以及筛迷路与眼眶和前颅底的解剖关系。鼻窦CT扫描在鼻窦炎病因分析、鼻内镜鼻窦手术设计及并发症预防等临床实践中具有重要意义。
