A case of intractable chronic osteomyelitis of the mandible accompanied with pathologic fracture and tardive dyskinesia

A case of severe chronic osteomyelitis of the mandible accompanied with fracture of the mandibular angle and tardive dyskinesia in a 78-year-old male is reported. As treatment with intravenous antibiotics or decortication was not effective, intra-arterial infusion of the antibiotics was performed. This therapy was very effective without complication. In our case, as the patient had had tardive dyskinesia in the past, it was considered that the severe chronic osteomyelitis was closely related to chronic tendoperiotitis caused by muscular overuse.
