摘　　要：目的 :探讨电子束CT(EBCT)三维重建在髁突骨折中的应用价值。　方法 :髁突外伤患者 11例 ,均给予临床检查、摄X线片、EBCT平扫及三维重建检查 ,评估髁突骨折的类型及骨折移位程度、选择适合的治疗方案。　结果 :EBCT具有扫描速度快、图像清晰的特点 ,其三维影像可以任意旋转和切割 ,从不同角度观察病变情况 ,正确地显示髁突骨折及其类型。　结论 :EBCT平扫及三维重建能客观地提供髁突骨折的所有特征 ,将两种以上重建方法结合 ,可以更清晰地显示和反映骨折线走向、碎骨片的移位 ,提高了髁突骨折的诊断和显示率 ,降低了误诊率 。Objectives:Clinical use of electron beam CT(EBCT) with three-dimensional(3D) reconstruction was studied in condylar fractures. Methods:Eleven cases of condylar traumas were referred to physical examination, radioautogram, EBCT and 3D reconstruction.Displacement degree and classification were evaluated and proper therapy selected. Results:EBCT have the characteristic of ultrafast speed scan and clear image, 3D images can be circumgyrated or incised arbitrarily that can show pathological changes in all direction and classification of condylar traumas. Conclusions:EBCT,3D could reveal all characterization of condylar fractures.More than two reconstruction method togather could show direction of fracture line and displacement bone piece well, improving diagnostic rate and reducing erroneous rate.EBCT can offer a lot of correct information for treatment plan.
