面部外伤以鼻骨骨折最为常见 ,对于鼻骨骨折一般X线检查也易做出诊断 ,但传统平片检查影像相互重叠 ,密度分辨率差 ,显示鼻骨情况尚可 ,但对上颌骨额突、泪骨、筛骨及诸骨缝影像显示不理想 ,容易造成部分漏诊。因此 ,我们采用冠状位HRCT扫描技术 ,对 75例鼻部外伤的患者进行检 Nasal fracture is the most common facial trauma, and it is also easy to diagnose nasal fracture by X-ray examination. However, the traditional plain film images overlap each other and the density resolution is poor, which shows that the nasal bone is acceptable. However, , Ethmoid bone and allograft images show unsatisfactory, easy to cause some missed diagnosis. Therefore, we used coronal HRCT scanning technique to examine 75 patients with nasal trauma
