摘　　要：目的探讨16层螺旋CT及其后处理功能在鼻及牙槽外伤骨折诊断中的应用价值。方法对46例鼻面部外伤病例采用16层螺旋CT扫描并进行多方位(MPR)、曲面(CPR)和三维(3D)重建,评价有无骨折和对骨折分型。结果25例鼻外伤中,确诊鼻骨骨折23例,排除骨折2例。21例牙外伤中,牙缺失伴有上、下牙槽骨折的15例,排除牙槽骨折6例。结论16层螺旋CT及其后处理功能在鼻及牙槽骨折诊断中具有实用价值,且可为法医学鉴定提供科学依据。Purpose To explore the application value of the nasal bone and dental alveoli. fractures in trauma with 16-slices CT and image post-processing. Methods 46 cases of nosal and dental trauma were examined by thin-section scanning with 16 MSCT and diagnosed with MPR, CPR, SSD and MIP. The final images were analysed and classified respectivetly. Results In 25 cases of nose trauma, 23 cases were confirmed nasal fracture and 2 cases were excluded. In 21 cases of dental trauma with loss of teeth, 15 cases were confirmed dental alveoli fracture and 6 cases were excluded. Conclusion MSCT and image post-processing can be helpful for confirmation or exclusion of the nasal bone and dental alveoli fractures .
