【摘要】 目的　探讨三维CT成像技术在面中部骨折中的应用价值 ,尤其是对颌面部复合、多发骨折的术前诊断和手术计划制定的意义。方法　对 47例面中部骨折进行螺旋CT扫描和三维成像。结果　 47例患者中 38例经手术治疗 ,9例为保守治疗 ,所有手术病例都证实了术前三维CT的诊断。结论　三维CT成像可使颌面部复杂性骨折的移位情况近似模型般再现 ,有益于选择最合适的手术方案更多还原

【Abstract】 Objective To study the value of 3D reconstructive technique in midfacial fractures,especially its significance in preoperative diagnosis and operation planning of complicated,multiple fractures in midface.Methods To preoperatively scan and reconstruct 47 fracture patients with spiral CT.Results 38 cases received operation which confirmed the preoperative diagnosis of 3D CT.The conservationed treatment was applied to other 9 patients.Conclusion The 3D reconstruction can reveal the complicted fractures in midface as approximate model, and benefit the selection of the most suitable plan before operation.更多还原
