Covid-associated osteonecrosis of the midface

Abstract

The purpose of our study the features of clinical manifestations and treatment of Covid-associated osteonecrosis of the midface (rhinocerebral form of mucormycosis). An analysis of the clinical features and results of surgical treatment of 35 patients with Covid-associated osteonecrosis of the midface was carried out. Difficulties in diagnosing of Covid-associated osteonecrosis led to late hospitalization and extensive surgical treatment with the huge defects formation. Due to the nonspecificity of clinical symptoms and the difficulties of early diagnosis and differential diagnosis of invasive rhinocerebral forms of mucormycosis, the aggressive clinical course with the formation of extensive defects in the midface, long and complex rehabilitation of patients with Covid-associated osteonecrosis of the midface, the vigilance of general practitioners is necessary and specialists: dental surgeons, maxillofacial surgeons, ophthalmologists, otolaryngologists, neurologists, regarding the possibility of developing invasive aggressive forms of mycoses in immunocompromised patients who have suffered a new coronavirus infection COVID-19.
