Surge of Mucormycosis in the Jaws Among COVID-19 Patients: A Case Series Highlighting the Role of Diabetes and Immunosuppression

Abstract

Mucormycosis is a life-threatening fungal infection caused by Mucorales species, frequently occurring in immunocompromised patients. This case series investigates the alarming rise in maxillary mucormycosis among post-COVID-19 patients in India and explores its correlation with uncontrolled diabetes and immunosuppressive conditions. This case series analyzed 52 patients, primarily with maxillary infections, to identify the association between COVID-19 and mucormycosis. Diagnostic methods included CT, MRI, and fungal cultures. Despite a low culture positivity rate, these combined methods were critical in assessing the infection and managing treatment. The study highlighted challenges in distinguishing infected tissues from healthy ones during surgical procedures. The study found that mucormycosis in COVID-19 patients led to severe complications, including sepsis and meningitis, often resulting in fatalities. Effective treatment strategies involved surgical debridement, antifungal therapy, and strict diabetes control. Early diagnosis and management were critical in reducing the risks of fatal outcomes. This study underscores a significant correlation between post-COVID-19 mucormycosis and pre-existing comorbidities, particularly diabetes mellitus. Early intervention combining radiological imaging, surgical debridement, and antifungal therapy is critical to improving clinical outcomes. The findings warrant further prospective studies to establish targeted prevention and treatment protocols.
