Abstract：Objective To discuss the application value of multi-slice spiral CT scan 3D reconstruction in the diagnosis and treatment of maxillofacial fractures.Methods 35 cases of maxillofacial fractures were used spiral CT two-dimensional reconstruction and 3D reconstruction, which could well display the zygomatic fracture and nasal bone fractures and mandibular fracture, fracture displacement and fracture in line.Spiral CT 3D image processing results were superior to spiral CT two-dimensional image processing results, the two image processing results and the results after the operation were compared and analyzed, the advantages and disadvantages of two kinds of image processing results were compared.Results 35 jaw fracture patients were used spiral CT two-dimensional reconstruction and three-dimensional reconstruction processing, which could show the fracture of the bone , nasal bone fracture, upper and lower jaw fractures.Spiral CT scan 3D imagining dealing result on fracture displacement and fracture line was significantly better than that of spiral CT scan 3D imagining dealing;Spiral CT 2D axial images could show all the sphenoid ethmoid maxillary fracture, while the spiral CT three-dimensional images could only show part of the fracture, effect was worse than that of two-dimensional images.Conclusion For maxillofacial fractures, the use of spiral CT two-dimensional image is the most basic diagnostic method.Using spiral CT 3D reconstruction,we can completely and accurately display space anatomical relationship of the bone and bone block displacement in the maxillofacial fractures, which has important value in guiding the design and improving the surgical treatment effect.
