Figure 1

Lateral three-dimensional volume rendering computed tomography images (a–d) and macroscopic images of hemimandibulectomy specimens from patients with ORN (a’–d’). Black arrowheads indicate posterior directions. Black box indicates area of intraoral exposed bone. (a) Patient 1. (a’) Black circle indicates macroscopic bone destruction of the medial side of cortical bone near the inferior margin of the mandible. (b) Patient 2. (b’) Black circle indicates bone destruction of the medial side of cortical bone near the mandibular angle. (c) Patient 3. (c’) Black circle indicates bone destruction of the medial side of cortical bone of mandibular ramus. (d) Patient 4. (d’) Black circle indicates apparent bone destruction of the medial and lateral side of cortical bone of mandibular ramus.
