Pediatric Allergic Fungal Rhinosinusitis: Does Age Make a Difference?

Background Allergic fungal rhinosinusitis (AFRS) is a hypersensitive response to fungi within the sinus cavity. Children represent a challenging group of patients with sinonasal disorders, as their sinus anatomy is not fully developed. This study aimed to determine the various clinical manifestations and management outcomes in children with AFRS. Methods A retrospective chart review of children who underwent sinus surgery for AFRS at a tertiary healthcare center between 2005 and 2021 was performed. Demographics, clinical manifestations, radiological and laboratory results, treatment regimens, complications, and recurrence rates were collected. Subanalysis was performed based on age at first surgery: group A (<13 years) and group B (≥13 years). Results Overall, 35 children underwent sinus surgery for AFRS during the study period. The mean patient age at the time of surgery was 14 years. Bilaterality was present in 15/35 (42.9%) patients and anosmia in 12/35 (34.3%). Polyps on examination were present in 31/35 (88.6%) patients and proptosis in 8/35 (22.9%). Sub-analysis revealed that group A showed less bilateral disease (11.4%) than group B (31.4%) and a lower Lund-Mackay score (median=11.50 and 17, respectively, p=0.002). Conclusion Age at surgery did not have an impact on the outcome. A high index of suspicion should be exercised when dealing with children with sinonasal symptoms that do not respond to routine treatment and should be investigated for chronic sinusitis.
