Abstract: | Diffuse sclerosing osteomyelitis (DSO) of the mandible is a poorly understood chronic disease. It is assumed to be a form of chronic osteomyelitis. Other forms of chronic osteomyelitis are chronic suppurative osteomyelitis (CSO) and osteoradionecrosis (ORN). This study aimed to investigate radiographic characteristics of DSO and compare these findings with the radiographic characteristics of CSO and ORN in order to radiographically distinguish these three diseases.In this retrospective study, 33 patients were clinically diagnosed with DSO (13), CSO (6), or ORN (14). The panoramic radiographs, computed tomography images, and magnetic resonance images of these patients were evaluated. Osseous and soft tissue changes were analysed.Patients with DSO showed extensive cortical and medullary sclerosis combined with subperiosteal bone formation, condylar process deformation, and hypertrophy and oedema of the masseter muscle. DSO patients showed no pathological fractures or sequestra, which were observed in patients with CSO and ORN.The radiographic characteristics that differentiate DSO from CSO and ORN include subperiosteal bone formation, condylar process deformation, masticatory muscle changes, and the absence of sequestra and pathological fractures. |
