Abstract
Several bones contribute to the bony skeleton of the face including the mandible, which forms the only freely mobile joint of the skull. The frontal bone, maxilla, zygomata and mandible contribute most to the shape of the face. The orbits, nose and para nasal sinuses form bony cavities contained by the facial skeleton.
There has been a rising incidence of maxillofacial injuries during the past decade as a result of an increasing number of assaults and motor vehicle accidents. The maxillofacial region
is one of the most complex areas of the human body.
Computed tomography is the imaging method of choice for an accurate diagnosis and for depicting the complex anatomic structures of the maxillo-facial region. Fracture lines, bony
fragments, and associated skeletal deformities are clearly identified by CT scan.
Compared to the 3D CT of 1990s, the latest CT has made significant improvement thus resulting in higher accuracy of diagnosis. Multidetector CT represents a breakthrough in CT
technology. It has transformed CT from a transaxial crosssectional
technique into a true 3D imaging modality that allows for arbitrary cut planes as well as excellent 3D displays of the data volume.
Previously, streak artifacts from surgical hardware made CT imaging almost impossible. With MDCT and improved reconstruction algorithms, imaging in the vicinity of hardware is much less of a problem.
