Figure 3

3D reconstruction and multiplanar reconstructions of computed tomographic images of an ovine skull. The 3 D model (a) shows the drill hole (red arrowhead) for targeting the emergence of the right facial nerve, which is located slightly to the left of the middle between the sutura parietooccipitalis (SPO) and the nuchal crest. A red asterix is placed in the middle of the burr holes for the fiducial marker post. The multiplanar reconstructions in the transverse (b), dorsal (c) and sagittal (d) plane demonstrate the burr hole in the different orientations. SPO: Sutura parietooccipitalis; SO: Squama occipitalis.
