The purpose of this study was to clarify the spatial relationship in presurgical
examination and to aid surgical planning and postoperative evaluation of patients with
facial bone injury.
For this study, three-dimensional images of facial bone fracture were reconstructed by
computed image analysis system and three-dimensional reconstructive program
integrated in computed tomography.
The obtained results were as follows:
1. Serial conventional computed tomograms were value in accurately depicting the
facial bone injuries and three-dimensional reconstructive images demonstrated an overall
look.
2. The degree of deterioration of spatial resolution was proportional to the thickness of
the slice.
3. Facial bone fractures were the most distinctly demonstrated on inferoanterior views
of three-dimensional reconstructive images.
4. Although three-dimensional reconstructive images made diagnosis of fracture lines,
it was difficult to identify maxillary fractures.
5. The diagnosis of zygomatic fractures could be made equally well with computed
image analysis system and three-dimensional reconstructive program integrated in
computed tomography.
6. The diagnosis of mandibular fractures could be made equally well with computed
image analysis system and three-dimensional reconstructive program integrated in
computed tomography.
