三维CT影像技术在颅面部骨折中的应用

3D-CT Application in the Craniofacial Fracture

目的 :探讨三维CT成像技术在颅面部骨折中的临床应用价值 ;方法 :对 12例颅面部骨折患者行三维CT检查 ;结果 :除 1例上颌窦内壁和蝶骨翼突骨折 ,三维CT未显示 ,二维CT显示 ,术中证实 ,3例眼眶内侧壁三维CT显示大小不同的缺损 ,如同空腔 ,造成假阳性外 ,余均清晰显示了骨折的部位、范围、骨块移位方向和距离 ;结论 :三维CT图像清晰 ,立体直观 ,为手术入路的设计 ,接骨板的选择提供了可靠的信息 ,可正确指导手术 。

Objective:To evaluate the value of 3d-CT application in the craniofacial fracture.Methods:12 cases of the craniofacial fracture were scanned by 3D-CT.Results:Medial wall of the maxilla and pterygoid process of the sphenoid bone of one case,being identified by 2D-CT,being proved by operation,was not identified by 3D-CT;Normal medial walls of 3 cases were wrongly presented defect by 3D-CT;All locations,ranges,directions,distances of the fracture,are clearly presented by 3D-CT in the others.Conclusion:3D-CT has some direct meaning for the reduction of the craniofacial fractures.
