Abstract

Observation of the porus acustics internus was possible only in cadaver and the dried temporal bone. We successfully observed this area in a living body by means of the surfacereconstructionthree dimensional images. The diameter of the porus measured by this method was similar to that obtained by the conventional method. Surface reconstruction-three dimensional images are dynamic and stereoscopic, and it allows us very useful and accurate observation for the surface of the temporal bone.
