Fig. 1. Computed tomography: 3D skull reconstruction, frontal view. A titanium mesh is visualized in the projection of the frontal bone defect. The image shows frontal lobe fragments forming the superior orbital wall after osteosynthesis

Fig. 3. An axial CT image. The arrow points to the edge of the plate that deforms the cranial contour. The image shows the difference in geometry between the cranial vault and the implant
Fig. 4. An axial CT cisternography image
Fig. 5. 3D reconstruction of the skull: CAD planning. The implant is larger than the defect size, which is necessary for more accurate restoration of the frontal bone shape at the planning stage
