Fungus Balls of the Paranasal Sinuses

Abstract

Fungal balls are extramucosal collections of fungal elements, usually localized to a single sinus cavity, commonly the maxillary sinus. They are usually of the noninvasive variety, and commonly seen in immunocompetent hosts. Occasionally a waning of the immunity can cause them to turn invasive. Much controversy exists regarding its management – medical as well as surgical. Endonasal evacuation of the involved sinus is usually all that is required to manage this condition.
