摘　　要：目的探讨螺旋CT在颌面部外伤中的诊断价值。方法选择29例重症颌面部外伤病例，将螺旋CT扫描容积数据传输至CT工作站行多重面重建（MPR）和三维重建（3D）。结果轴位图像提供外伤的基本信息，MPR从任意平面全面观察骨折及其周围情况，3D可观察骨折的空间立体关系。结论螺旋CTMPR及3D弥补了轴位图像的不足，可以全面立体地显示病变，对于术前制定手术计划及术后评价手术效果具有重要作用。Objective To investigadte the application of helical CT in the diagnosis of maxilla-facial trauma. Methods 29 cases of serious maxilla-facial trauma were selected. Allreformatting（MPR）and 3-dimensional reconstruction（3D）. Results Bone fracture was well demonstrated stereoscopically and could be viewed from any desired plane by MPR and 3D.Conclusion MPR and 3D of maxilla-facial fracture serve as a primary guide in surgical planning to improve the understanding of anatomic relation with complex fracture and a important value following-up survey.
