[Traumatic changes of the base of skull and facial bones in computerized tomography]

During emergency CT examination, impression fractures of the skull, fractures of the base or of facial bones may be diagnosed in addition to possible traumatic intracranial manifestations. If the fractures extend to the base of the skull or to the facial bones, a possible involvement of foraminae, orbitae or nasal sinuses may be recognized. The extent of dislocation of loose bone fragments may be visualized without special conventional X-rays.
