【摘要】 目的：进一步了解中国人鼻区Ｘ线解剖细节。方法：对２３个头颅标本的鼻区照片及鼻区ＣＴ扫描，观察分析不同投照体位所得影像中各相邻的结构关系，并与２０例正常人鼻区影像进行比较。结果：（１）鼻区４５°半轴位投影，梨状孔缘线与解剖学上的梨状孔缘线有一定差异；（２）鼻骨侧位投影不可见骨性鼻中隔前缘。结论：听眶线与台面成４５°半轴位投影能更大限度暴露鼻区结构，鼻区骨折检查首选半轴位和侧位片；要区分鼻骨与上颌骨额突及周围的细致结构，ＣＴ检查是个好方法。更多还原

【Abstract】 Objective:To further find out the radiological anatomical details of the Chinese nasal region.The nasal region of 23 skull samples was examined by radiography and CT scan.The imaging relationship of neighbouring structures obtained from various positions and views was observed,analysed and compared with those of 20 normal patients.Results:(1)The outline of the pyriform aperture was difference between at 45°semi-axial nasal view and in anatomy;(2)The anterior fringe of the nasal spetum was invisible on the laterial view of the nasal bone.Conclusion:The structure of the nasal region can be maximally revealed on semi-axial nasal view with its OM line at 45° with table.Semi-axial and lateral views are of choice in examing fracture of the nasal region.CT is a good method for distinguishing the nasal bone from the frontal process of the maxilla and other meticulous structures.更多还原
