title: [The value of CT in the diagnosis of traumatic fronto-basal CSF fistulae (author's transl)].
abstract: In 20 patients with fronto-basal CSF fistulae, radiograms, tomograms and CTs in the axial and coronal projection were taken before operation. The evaluation showed that small fractures of the cribriform lamina could be demonstrated most clearly by CT with narrow coronal sections. Although the resolution properties of CT is still inferior to that of tomography for small osseous fissures, good CT results could be achieved by the better demonstration of accompanying mucosal swelling and/or small effusions. Fractures of the walls of the frontal sinuses, on the other hand, where shown better by tomography and those of the frontal calotte by normal radiograms.
