RESUMEN
Fractures of the mandibular condylar process are common and account for up to 40% of all mandibular fractures. Penetration of the condylar head into the middle cranial fossa is, however, rare. We have found reports of only 43 cases since 1834. The diagnosis of intracranial condylar dislocation is difficult, there are usually no particular symptoms or neurological signs. As a result, detailed radiological studies are necessary. In the absence of clear radiographic images of the condylar structures, computed tomography (CT) is essential to locate the fragments and to investigate and monitor intracranial lesions. This paper describes the diagnostic and surgical procedures used in two cases of condylar dislocation and discusses them with reference to previous cases. The use of a titanium screw, which was positioned intracranially in the first case, has not, to our knowledge, been described previously.

Computed tomography (CT) of parotid gland was performed on 40 patients, immediately following sialography. The results of the combined CT-sialography were compared with those of sialography alone and are presented here. We have come to the conclusion that the main indication for this method, in the study of the parotid gland, is the mass-pathology, particularly situated in deep-lobe and in the pharyngo-maxillary space.
