To analyze the dynamics of symptoms in patients with COVID-19 associated sino-orbital mucormycosis. We describe a series of 13 patients with COVID-19 associated sino-orbital mucormycosis aged 43 to 80 years diagnosed from August to October 2021. All of the patients had a severe disease and required noninvasive ventilation or intubation and administration of dexamethasone. 12 out of 13 patients (92.3%) suffered from diabetes mellitus. Symptoms of fungal infections of the nose and paranasal sinuses appeared in the interval from 7 to 25 days of hospital stay, most often in the second week (from 8 to 12 days). According to clinical and CT features the patients were divided into three groups, combining similar phenotypes of the disease. Group 1 - 1 patient with sinonasal mucormycosis, destruction of the alveolar ridge and the hard palate. Group 2 - 12 patients with sino-orbital mucormycosis. We noted, that in cases of bilateral sinus lesions orbital complications were unilateral in all patients, on the side of more severe lesion. Group 2 was divided into 2 subgroups: subgroup 2a included 2 patients with the superior orbital fissure syndrome: ptosis, proptosis, ophthalmoplegia, periorbital pain, pain or hypoesthesia of half face; subgroup 2b included 10 patients with the orbital apex syndrome, who, in addition to the above symptoms, had loss of vision and conjunctival chemosis. Group 3 - rhino-sino-cerebral mucormycosis. 2 patients from subgroup 2b were transferred to this group due to the intracranial spread of the process and focal neurological symptoms. Clinical forms of mucormycosis reflect successive stages of invasive spread of fungi.
