[The acoustic internal meatus--tomographic and autopsy findings]

The authors compared the autopsy and tomographic findings of meatus acusticus int. In addition to the dimensions of meatus acusticus int. the authors also evaluated its shape and measured the distance between fossa jugularis and lower wall of fundus. The mean values of six parameters observed and measured on the cadavers and the tomograms differed in the following way: three parameters up to 0.5 mm and three by 0.8 mm, 1.1 mm and 1.2 mm, respectively. In eight patients the tomograms were evaluated as pathological; these were described in detail and put into relation to CT, CT-cisternomeatographic or the operation finding.
