Diagnosis and Management of Candida and Other Fungal Infections of the Head and Neck

Abstract

Fungi are common inhabitants of the oral and nasal mucosa, and therefore the differentiation between colonization and pathogenicity in the setting of upper respiratory tract infection symptoms can be difficult. Fungal head and neck infections occur in both immunocompetent and immunocompromised persons, and patients with neutropenia, diabetes mellitus, corticosteroid use, and HIV infection are particularly susceptible to serious and potentially life-threatening infections. Invasive fungal head and neck infections generally require extensive surgical debridement and prolonged systemic antifungal therapy, and frequently carry a poor prognosis when the underlying immunosuppression cannot be corrected. In contrast, noninvasive fungal head and neck infections often respond to short courses of systemic or topical antifungal therapy, or require limited surgical debridement alone.
