The problem of treatment of pyoinflammatory diseases (PID) of the face and neck is relevant for both dentists of polyclinics and maxillofacial surgeons in hospitals. About 50% of those in maxillofacial hospitals, and about 20% of those who seek help from a dentist and a surgeon of polyclinics, are patients with inflammatory diseases of the maxillofacial region (MFO), among them - 60-80% of patients with abscesses and phlegmons, the frequency of which has increased by 1.5–2.0 times over the past decade. There has been a steady growth of atypical and severely flowing progressive phlegmon, spreading simultaneously in several cellular spaces, with the development of such formidable complications as sepsis, contact mediastinitis, and thrombosis of the cavernous sinus of the dura mater. Low-symptom “erased” forms of phlegmon are found among 13.4–22% of patients, are characterized by a long course and are difficult to diagnose, which contributes to late hospitalization and untimely treatment started. Microbial etiology of HVZ CLO is due to the localization of the primary process (connection with the oral cavity, teeth).
