Temporal squama comminuted fracture: 3D reconstruction of the exocranial surface of the right temporal bone of sample S1 with a volume-rendering technique. Comminuted fracture of the mastoid with extension in the petrous bone and important depression. In the center of the image is highlighted the aspect of bone depression (black arrows) that keeps the ball contour impaction at the junction with the mastoid and temporal scales; the main fracture lines are marked by dashed white lines. The sample position is indicated by marginal marks with white letters: S indicates superior; I, inferior; A, anterior; and P, posterior; black letter marks: ZP, zygomatic process of the temporal bone; P, parietal portion; S, scaly portion of the temporal bone. EAM, the external acoustic meatus, is indicated by the white arrow.
