Allergic fungal sinusitis, often missed, involves fungal hypersensitivity in nasal polyps. Diagnosis requires specific tests, and treatment includes surgery and topical steroids to prevent recurrence.
Area of Science:
- Otolaryngology
- Allergy Immunology
Background:
- Allergic fungal sinusitis (AFS) is an emerging condition within paranasal sinus mycoses.
- Diagnosis of AFS can be challenging despite its prevalence.
Purpose of the Study:
- To identify the diagnostic criteria and clinical features of allergic fungal sinusitis.
- To report on the management and outcomes of patients with AFS.
Main Methods:
- Retrospective analysis of 28 allergic nasal polyposis cases over two years.
- Diagnosis based on Type I hypersensitivity, eosinophilic mucus, direct microscopy of hyphae, and fungal culture.
- Histopathology excluded tissue fungal invasion.
Main Results:
- 11 of 28 patients (39%) were diagnosed with AFS.
- Aspergillus flavus was the most common fungus isolated (9/11 patients).
- Associated conditions included asthma (5/11) and proptosis (4/11), with nasal obstruction in all.
Conclusions:
- AFS is a significant subgroup of allergic nasal polyposis.
- Multifaceted diagnostic approach is crucial for identifying AFS.
- Surgical debridement combined with topical steroids is effective for managing AFS and preventing recurrence.
