Abstract


Objective The aim of this study is to explore the diagnosis and clinical application value of computer-assisted three-dimensional reconstruction technique in injuries of maxillofacial and orthognathic surgeryMethods70patients of maxillofacial trauma patients and6patients of orthognathic osteotomies were included in this study。Firstly, we will made the trauma epidemiological statistical analysis of maxillofacial trauma patients; and all trauma patients were performed by X-ray films、2D spiral CT scan and3D reconstruction imaging, finally, comparing with the results of analysis, and summarize the clinical application of3D reconstruction technique in maxillofacial trauma。6patients of orthognathic osteotomies image data obtained by spiral CT scan made3D reconstruction, followed by its measurement, analysis and surgical simulation, and finally determine the surgical results.Results70cases of maxillofacial trauma patients, the accuracy rate of X-ray,2D CT and3D CT were88.1%,97.6%and97.6%,X-ray was significant lower than97.6%of3D CT (P<0.05). there were212fractures by Computer-assisted three-dimensional reconstruction technique of image of70case, Compared with the2D CT examination method, computer-assisted three-dimensional reconstruction technique stereoscopical and clearly shows the maxillofacial fracture site, type, displacement of fracture fragments and maxillofacial three-dimensional morphological changes; The technique can be used to raise the level of clinical diagnosis and treatment of maxillofacial deformity, and promote the communication and cooperation between patients and doctors.Conclusion The technique make up for less than ordinary X-ray and2D CT axial images-display of lesions in the full three-dimension, which has an important clinical value in preoperative diagnosis, surgical planning and post-operative effect evaluation in maxillofacial trauma and orthognathic surgery, and could be used as a conventional imaging methods, Also was the data base of oral computer-aided surgical.
