Post-COVID fungal infections of maxillofacial region: a systematic review.

With the advent of coronavirus disease (COVID-19) pandemic, a wide range of life-threatening maxillofacial fungal coinfections have also been observed in patients. We conducted this systematic review to collate and evaluate the data to enable clinicians to understand the disease pattern and types of mycosis and provide meticulous management of these infections in COVID-19 patients. The review was carried out in accordance with Preferred Reporting Items for Systematic Review and Meta-analysis guidelines. A systematic electronic literature search was conducted on major databases using keywords in combination with Boolean Operators. Manuscripts discussing cases of maxillofacial fungal infections in COVID-19 patients were included. A total of 11 studies were systematically reviewed to assess the fungal coinfections in COVID-19 patients. Twenty-one cases of mucormycosis, 58 of candidiasis, and 1 each of aspergillosis and mixed infection were observed in the region of head and neck. Significant increase in invasive fungal infection is evident in patients suffering from COVID-19 which could be due to immunosuppression and other pre-existing comorbidities. Early diagnosis and intervention like systemic antifungals or surgical debridement is mandatory to reduce morbidity and mortality.
