摘　　要：目的 :通过对眶尖部CT影像表现和断层解剖标本的观测 ,探讨眶尖部诸结构出现的CT扫描层面和临床意义。方法 :用 3 3侧干燥成人颅骨行轴位横断CT扫描 ,结合 10例颅脑断层标本进行解剖学观测。结果 :眶上裂和眶下裂分别出现于CM基线上、下 15mm和 10mm范围内 ,视神经管影多见于CM基线上方 7～ 12mmCT扫描层面。结论 :颞骨岩锥上部层面是观察眶上裂和视神经管的最佳层面 ,对眶尖部病变的临床诊断和治疗具有重要意义。Objective:To determine the appearance level of the orbital apex in CT images and its clinical significance.Methods:The anatomy study of the orbital apex was perfomed on the transverse axial scanning images of 33 dry half skulls and the section of 10 cadavers heads.Results:The superior and inferior orbital fissure could be observed at the range of +15 mm and 10 mm with the CM baseline.The optic canal was at the range of +7 to +12 mm with the CM baseline.Conclusions:The section of the dorsum sella and the superior part of the petrous part of temporal bone was the best sechion for observing the superior orbital fissure and optic canal.This data was very important for the clinical diagnosis and treament of the diseases in orbital apex.
