      ASPECTS OF THE TEMPORAL BONE IN FETUSES (Abastract): The temporal bone, which has the most complex aspect on the exterior and interior surfaces, consists of parts with different embryological origins. Their form is outlined at the end of the embryonic period, and is gradually changing during the fetal period and even after birth. In order to evaluate these changes, we included in our study fetal skulls with different ages. We photographed the skulls from different angles then the study was completed with a CT-exam of the same skulls and a 3D reconstruction of the CT images. After analyzing and magnifying the photos and the computed-tomography images and reconstructions, we observed the limits between the different parts of the temporal bone, from the beginning of the fetal period until the end of the same period; we also observed the obvious changes suffered by the internal and external aspects of the temporal bone, during this period and the big differences between a fetal and an adult skull regarding the temporal bone. At the end of the fetal period, the temporal bone hasn’t reached its final aspect; between its parts there are still articular interlines or sutural lines, observed also between the two components derived from the periotic capsule, the petrous part and the mastoid.
