[High resolution computer tomography of the middle and inner ear].

High-resolution CT enables exact visualisation of the bony structures of the petrous bone; at the same time, all relevant nerval, vascular and muscular elements of the middle and inner ear are visualised. A wider range of findings can be attained in this region of wide differences in density than via conventional pluridirectional tomography. The normal anatomy of the petrous bone is demonstrated via CT series of slices in axial and coronal projection.
