CT reconstructions one week after surgery (0.6 mm thick, non-overlapping sections, 60 mA, 120 kV) acquired using a SOMATOM Definition CT scanner (Siemens AG Medical Solutions, Erlangen, Germany) and visualized using OsiriX v.5.7.1 64-bit (Bernex, Switzerland). The left reconstruction illustrates a sagittal view of the position and depth of the drill holes in relation to the cranial cavity. Note that the calvaria thickness decreases toward the anterior part. On the right, the three sub-studies, 1A/1B, 2A/2B, and 3A/3B, are illustrated in relation to the cranial sutures.
