摘　　要：目的探讨MSCT的三维重建对下颌骨骨折的临床手术应用价值。方法对13例下颌骨骨折进行了MSCT检查,在此基础上进行MPR、SSD、CPR重建,观察它们显示下颌骨结构和骨折的情况。结果 SSD能清楚地显示整体下颌骨的结构、颞颌关节;MPR能多方位显示其解剖及周围的关系;CPR能将下颌骨展平,可显示弯曲部位或不规则走行的骨折。结论 MSCT三维重建技术能够将下颌骨横断图像转化为可以任意旋转的立体图像,能够详细了解其解剖结构的空间关系,清楚地显示骨折的情况;对临床诊治或手术有重要的指导意义。Objective To explore the reconstruction of mandibular MSCT fractures of the clinical application value. Methods 13 patients with mandibular fractures were MSCT inspection,based on MPR,SSD 590 series,CP R reconstruction,observe them display mandibular structure and fracture. Results can be clearly shows that the whole SSD 590 series of mandibular structure,the temporomandibular joint,To show the MPR multidimensional relations; and the surrounding CPR can be flattened,can show mandibular bending parts or irregular go done fractures. Conclusion MSCT three-dimensional reconstruction technique can be transformed into cross-sectional images can be mandibular arbitrary rotation of stereo image,detailed understanding of the anatomical structure of spatial relations ,clearly shows that the fracture of the situation,For clinical diagnosis and surgery has important guiding significance.
