Complications of COVID-19 in the maxillo-facial region: Clinical case and review of the literature

COVID-19 is currently causing a pandemic around the world. With the increase in the number of patients, there was a slight increase in the incidence of various complications. In particular, infectious and inflammatory diseases of the face and jaw are observed in patients with COVID-19 in the early infectious stages of the disease, as well as in the late stages. In the previous literature, as a sign or complication of COVID-19 were mentioned cases of changes in the oral cavity - ulcers, rashes, and inflammation of salivary glands. The conditions presented in this article are a serious complication of COVID-19, radically different from the usual course of osteomyelitis, in which the patient has a course with a predominance of long-term, chronic-progressive, atrophic processes. Treatment was somewhat ineffective due to local chronic inflammation (pansinusitis), metabolic, microcirculatory, immune, and coagulation disorders in patients.
