This article presents the results of a morphological examination of facial mucosa complications after COVID-19. Infection of patients with COVID-19 with mucormycosis in the oral cavity is manifested in the form of discoloration of the mucous membrane in the area of the palate, swelling, ulcers, necrotic foci on the palate, hard palate and jaw bones, and the dark surface of the bone surface (Brandao et al ., 2020). It should be borne in mind that the recent emergence and development of mucormycosis with COVID-19 is not considered to be fully interrelated, but sufficient causes and conditions for the occurrence of this process during the pandemic, as well as the presence of somatic comorbidities, chronic microbial foci in patients.
