Figure 1.

Radiological documentation showing the effect of surgical treatment of mandibular head fractures (examinations were acquired 12 months after osteosynthesis). A pantomogram radiograph is shown in the center as an overview study and CT coronal sections through the mandibular heads are shown on the sides. In the CT scan, the union and position of the headless compression screws can be accurately assessed (volumetric study makes it possible to obtain any cross-section). This patient had an additional fracture in the rim of the mandibular body on the left side. It was treated with lag-screws. Please note the small depression in the articular surface of the left mandibular head (CT image on the right side of this figure). It appears to be the result of a tiny shift between the fixated bone fragments. This shift, however, changes the height of the mandibular ramus.
