目的探讨MSCT斜位多平面重建诊断鼻骨骨折的价值。材料和方法应用16排螺旋CT,对18例鼻外伤患者行横断面扫描和多平面重建,并分析结果。结果18例中,3例X线侧位片显示阴性,CT图像显示骨折线。单纯鼻骨骨折12例、合并鼻中隔骨折3例、合并上颌骨骨折3例、鼻骨线形骨折13例、粉碎性骨折5例。显示鼻骨骨折线全面、可靠,对碎骨片的数目、来源、移位或塌陷的情况显示清晰。结论斜位多平面重建诊断鼻骨骨折优于X线片和常规CT轴位像。
Objective To investigate the value of MSCT oblique multiplanar reconstruction in the diagnosis of nasal fracture. Materials and Methods Using 16-slice spiral CT, 18 cases of nasal trauma patients underwent cross-sectional scanning and multiplanar reconstruction, and analyzed the results. Results 18 cases, 3 cases of X-ray showed negative, CT images show the fracture line. Simple nasal bone fracture in 12 cases, nasal septum fracture in 3 cases, combined maxillary fracture in 3 cases, nasal bone linear fracture in 13 cases, comminuted fracture in 5 cases. The nasal bone fracture line was shown to be complete and reliable, showing clearly the number, origin, displacement or collapse of the fragments. Conclusion The diagnosis of nasal bone fracture by multiplanar reconstruction is superior to X-ray film and conventional CT imaging.
