[X-ray tomography in fractures of the temporal bone and injuries of the ossicula (author's transl)].

Since a high percentage of cross-fractures of the temporal bone cannot be verified in standard projections, tomography is indicated under clinical aspects. With this technique even small fractures concerning the meatus acusticus internus, the labyrinth, and the proximal part of the canalis facialis can be diagnosed. Experimental data concerning longitudinal fractures with facial palsy show the course of the fracture but not the exact point of the lesion. Additional information will be given to verify luxations or displacement of the ossicula.
