Osteomyelitis of the Jaws: Evolution and Clinical Relevance of Classification Systems

Abstract

Osteomyelitis (OML) of the jaws is an inflammatory condition of bone that predominantly    arises from odontogenic infections and is influenced by the unique anatomical and vascular characteristics of the maxillofacial skeleton. Unlike osteomyelitis of long bones, jaw osteomyelitis demonstrates varied clinical behaviour, ranging from acute suppurative infections to chronic, non-suppurative sclerosing forms. Over time, several classification systems have been proposed based on clinical course, presence of suppuration, radiographic extent, aetiology, and pathogenesis. These classifications play a crucial role in diagnosis, treatment planning, and prognostic assessment. This narrative review aims to comprehensively summarize and critically analyse the various classification systems of osteomyelitis of the jaws, highlighting their clinical relevance and limitations. Understanding these classifications allows clinicians to tailor management strategies and improve patient outcomes.
