Summary:Complicated and severe ONJ cases are collected in the stage III of clinically based 2009 AAOMS staging system; possible signs are mandible fracture, skin fistula, sinus or nasal tract. Computed Tomography (CT) scan is able to show real bone lesion involvement, beside the only clinically detectable signs. The researchers reviewed CT scan of ONJ patients, classified as stage II and III according to the clinical AAOMS staging system, and we classified them according to Italian SIPMO-SICMF clinical-radiological staging system, looking for the main radiological aspects of advanced cases. CT scans of maxilla and mandible were performed by a spiral multidetector scanner. They reviewed 35 staging time CT scans. There were 4 advanced cases: M/F 2/2; disease was breast cancer, prostate cancer, renal cancer, osteoporosis in Rheumatoid Arthritis. All 4 cases were stage III in both staging systems. CT aspects: 2 patients showed mandible fracture, 3 cutaneous fistulae, 2 maxillary sinus involvement, 1 extension to nasal bone, 2 presence of a sequestrum or bone fragments, 3 soft tissue involvement.
