Pediatric Allergic Fungal Sinusitis: A Clinical Review.

Abstract

Allergic fungal sinusitis (AFS) is the most common type of fungal sinus infection. AFS is a robust allergic reaction to inhaled soil fungi that causes sinus inflammation, and the fungal debris then accumulates in the sinus cavities. This accumulation can cause nasal polyps, facial pain and pressure, bone remodeling of the face, and even bone erosion, which can cause damage to the eyes and brain. AFS can also cause thick, sticky nasal mucus and postnasal drip, and it can affect the sense of smell. Most patients with AFS are adolescents who also have chronic symptoms of allergic rhinitis and asthma. Endoscopic sinus surgery to remove the disease and open the sinus cavities is the main treatment approach. Adjuvant immunotherapy is helpful in reducing the inflammatory response and preventing future recurrence of this allergy-mediated condition. [Pediatr Ann. 2021;50(7):e297-e303.].
