摘　　要：目的:探讨鼻骨骨折的MSCT表现及诊断误区。方法:回顾性分析251例鼻骨骨折患者,均行MSCT扫描及图像后处理,包括MPR、MIP及VR。结果:251例骨折中,单纯性骨折84例,60例无明显错位,24例明显错位;粉碎性骨折123例;复合型骨折44例。轴位上正常结构误诊为骨折11例,鼻骨孔6例,缝间骨2例,鼻骨变异(勾形鼻)1例,鼻骨内面压迹2例。结论:MSCT及其后处理能明确地显示鼻骨骨折情况。Objective：To detect the applicable applicable vale of multislice CT and postprocessing techniques in diagnosis of na-sal fracture .Methods ：264 patients with nasal trauma performed multislice CT scanning ,all data were postprocessed with MPR （multiplanar reformation） ,MIP （maximum intensity） ,VR （volume rendering） .Results：251cases were nasal fracture ,including simple fracture without significant dislocation in 60 cases ,simple fracture with significant dislocation in 24 cases ,and comminu-ted fracture in 123 cases .On axis position ,11 cases of normal structure were misdiagnosed as fracture ,including 6 cases of nasal aperture ,2 cases of sutural bone ,one case of nasal mutation （hook-shaped nose） ,and 2 cases of the inner pressure trace of na-sal .Conclusion：Multislice CT and postprocessing techniques can show the nasal bone fracture clearly .
