Aseptic osteonecrosis of the maxilla after severe COVID-19 infection and its treatment.

ABSTRACT

The course of the new SARS-CoV-2 (COVID-19) is unpredictable and is still being investigated. Although the majority of complications are expected to affect the respiratory system, there have been reports in literature concerning the adverse effects of the infection on bone and joint tissue. Several complications have been observed in the maxillofacial area in people who suffered from the infection, including osteonecrosis and osteomyelitis of the jaw. These complications have been subject to various hypotheses. They may result either from the disease pathogenetic mechanism or from a response to the therapeutic modalities used to treat the underlying disease, and overuse of particular medications - glucocorticoids, antirheumatics, interleukin-6 inhibitors, and antibiotics. This article presents a case of osteonecrosis of the maxilla after severe COVID-19 infection.
