The advance of endoscopic endonasal surgery allows limited surgical resection in chronic rhinosinusitis. An accurate topographic evaluation of diseases and individual morphologic variation are necessary for this functional surgery. The preoperative radiological investigations require a precise knowledge of ethmoid and osteo-meatal unit anatomy. Thin sections by high resolution CT were performed in coronal plane. The anatomical land marks and the ethmoidal bony roots, which allow a study of the osteo-meatal unit and ethmoid air cells system, are showed. Like endoscopic view, coronal slices better display the different grooves for paranasal sinus draining and their relations with the ethmoid.
鼻内镜鼻内手术的进展使得慢性鼻窦炎的手术切除范围得以受限。对于这种功能性手术而言，准确的疾病局部解剖评估和个体形态变异是必要的。术前影像学检查需要精确了解筛窦和骨-鼻窦复合体的解剖结构。采用高分辨率CT在冠状面进行薄层扫描。展示了有助于研究骨-鼻窦复合体和筛窦气房系统的解剖标志和筛窦骨根部。与内镜视野一样，冠状面切片能更好地显示鼻窦引流的不同沟道及其与筛窦的关系。
