[The value of three-dimensional helical CT imaging in the diagnosis of maxillofacial fractures].
To assess the diagnostic value of three-dimensional (3D) helical CT imaging in the cases of maxillofacial fractures. 25 trauma patients were examined with thin-slice CT scan and 3D reconstruction. Three-dimensional images reconstructed from helical CT clearly and stereoscopically demonstrated the location, shape and extension of maxillofacial fractures. 3D helical CT imaging can provide valuable information in demonstrating space relationships of maxillofacial fractures.
