A hospital-based observational study on clinical and radiographic findings in COVID-19 associated rhinomaxillary mucormycosis

Mucormycosis is a rare, rapidly spreading, fulminant, opportunistic infection that is caused by a group of filamentous molds. During the second wave of COVID-19 India reported most of the cases of mucormycosis which is termed as COVID-19-associated mucormycosis (CAM). Aim: The purpose of this study is to describe and understand the clinical and radiographic findings related to COVID-19 associated rhinomaxillary mucormycosis. Methods: In this observational study 76 individuals with proven rhinomaxillary mucormycosis were included. The demographic profile, predisposing factors, anatomic structures involved, oral manifestations, radiographic findings management, and 90-day mortality were recorded and analyzed. Results: Among 76 individuals with COVID-19-associated rhinomaxillary mucormycosis diabetes mellitus was present in 93.42% of cases. Almost all patients received corticosteroids during COVID-19 treatment. The maxilla was most commonly involved in around 98.6% of cases. Interestingly 1 case involving the mandible was noted and the maxillary sinus was the most commonly involved. Mortality occurred in 1.31% (n=1) of cases. Conclusion: Diabetes was the most common predisposing factor. Administration of corticosteroids was evident. A considerable number of patients developed diabetes during the treatment of COVID-19. Early signs and oral manifestations of rhinomaxillary mucormycosis play a pivotal role in the early diagnosis and prompt treatment to reduce mortality and morbidity in COVID-19 associatedrhinomaxillary mucormycosis patients.
