Abstract

PURPOSE
The purpose of this study is to compare the diagnostic accuracy and usefelness of three dimensional CT, plain radiography and two-dimensional axial CT in cases of maxillofacial fracture.
MATERIALS AND METHODS
Plain radiography, two dimensional axial CT, and three dimensional helical CT images of eighty-two maxillofacial fractures in 45 patients were retrospectively analyzed according to detectability of fracture and displacement. The diagnostic accuracy of each modality was analysed using the Ridit method.
RESULTS
Two- and three-dimensional CT were superior to plain radiography in evaluating fracture and displacement (p=0.001, 0.039), though the type of CT used did not cause significantly variation in the accuracy with which fracture and diferrent were diagnosed.
CONCLUSION
Three dimensional helical CT is useful not only in the detection of fracture but in the evaluation of displaced maxillofacial fractures, especially if these are multiple and the complex.
