Abstract

The purpose of this study is to compare the diagnostic accuracy and usefulness of three-dimensional CT, two-dimensional CT in case of blow-out fracture. Two-dimensional CT, three-dimensional CT images of twenty-four blow-out fracture and soft tissue incarceration. Two dimensional CT was superior to three-dimensional CT in evaluating orbital bone fracture and soft tissue incarceration. But, three-dimensional CT was more useful to identify of orbital bone fracture than two-dimensional CT in associated facial bone fracture. Coexamination with two-dimensional axial & three-dimensonal CT was useful not only in the detection of fracture but in the evaluation of soft tissue incarcerated blow-out fracture.
