Elongation of the mandibular coronoid processes were easily detected bilaterally in both 3D images (Figure 1A and B) and axial scan (Figure 1C). Vertical measurement between the second line and the top of the coronoid process revealed the length of the elongated coronoid (Figure 1A and B).

According to 3D view (Figure 2A and B) elongation of the mandibular coronoid processes were observed bilaterally. On the axial scan, the distance between the coronoid process and the inner face of the frontal part of the zygomatic bone was 17.4 mm on the right and 14.8 mm on the left side (Figure 2 C).

The lengths of the coronoids were 8.3 mm on the right and 6.1 mm on the left side (Figure 3 A and B). On the axial scan, the distance between the coronoid process and the inner face of the frontal part of the zygomatic bone was 11.7 mm on the right and 13.2 mm on the left side (Figure 3 C).
