X-ray features and diagnostics of purulent-necrotic lesions of the jaws

Abstract

X-ray data of 750 patients with odontogenic and non-odontogenic osteomyelitis of the jaws aged 18 to 65 years were studied. The results of orthopantomography, panoramic zonography of facial bones, telerentgenography of the skull, intraoral radiography, computed tomography of the maxillofacial region are analyzed. The radiological characteristics of odontogenic acute, subacute, chronic and primary chronic osteomyelitis, hematogenic and posttraumatic osteomyelitis, radiation, bisphosphonate and phosphorus necrosis of the jaws are presented, taking into account differential diagnosis. The radiological semiotics of osteomyelitis of the jaws is diverse, since the features of the manifestation of osteomyelitis depend on the etiology, stage of the course and form of the bone inflammatory process. Orthopantomography is a method of primary diagnosis of osteomyelitis of the jaws. The use of computed tomography contributes to the accurate identification of the structure of the affected area, the magnitude of the destruction of anatomical details of the jaws and the boundaries of the spread of the purulent-necrotic process.
