Abstract: Objective To evaluate the application of Multi-slice Spiral CT(MSCT) in the Maxillofacial Trauma. Materials and Methods 20 case with maxillofacial trauma were scanned by MSCT, all images were performed with Shaded surface display(SSD), Volume rendering(VR) and Multi-plane reconstruction(MPR). Results SSD and VR can display the obvious craniofacial fractures clearly and stereoscopically. MPR can display the craniofacial fractures wholly and accurately, especially the tiny fracture in the deep. Conclusions MSCT with reconstruction can display the cranio-facial fractures wholly, accurately and stereoscopically,and plays an important role in both diagnosis and clinical managements.
