Mucormycosis of the bones of the facial skull, nasal cavity and paranasal sinuses in patients with COVID-19.

ABSTRACT

Currently, the relevance of the issues of diagnosis and treatment of invasive fungal diseases has increased significantly due to the pandemic of a new coronavirus infection COVID-19 and the massive use of corticosteroids for the treatment. The key success factors in the outcome of invasive fungal diseases are early diagnosis and treatment, including the applying of an adequate systemic antifungal therapy and surgical treatment. Extensive areas of mycotic lesions of the facial bones and paranasal sinuses are life-threatening conditions due to anatomical proximity to brain structures and a high risk of dissemination of I invasive fungal diseases with a fatal outcome. The objective of this work was to study the risk factors, possible pathogenesis, diagnosis and treatment strategy of invasive fungal diseases of the orofacial region in convalescents of COVID-19. We present case-series data on six patients in the clinics of maxillofacial surgery and otorhinolaryngology of the Pavlov First Saint Petersburg State Medical University over the period of 2021-2022. Predisposing factors, clinical and radiological symptoms, features of diagnosis, therapy and surgical strategy were analyzed. The presented observations confirm the relevance and danger of complications after a COVID-19 in the form of the development of invasive fungal diseases with damage to the maxillofacial region caused by mucormycetes and Aspergillus spp., as well as importance of early diagnosis and treatment.Copyright © 2021, Interregional Association for Clinical Microbiology and Antimicrobial Chemotherapy.
