Incidence of Allergic Fungal Sinusitis among patients with nasal polyps and role of Lund-Mackay scoring in its diagnosis.

Abstract Objective: The objectives of the study were to determine the frequency of AFS among patients with nasal polyps and to compare the Lund-Mackay scores of patients with and without AFS.

Methods 114 patients with sinonasal polyposis undergoing surgery were included. Patients were categorized as case of AFS when histopathology showed allergic mucin with fungal hyphae and culture was positive for fungal growth. Lund-Mackay scoring based on CT PNS of each patient was done and mean scores of AFS and non AFS patients were compared.

Results Mean age of 114 participants was 37.3 ± 15.3 years. 61 (53.5 %) of them were males. 27 (23.7 %) patients met the AFS criteria. 16.7 % of our patients were asthmatic and a significant relationship was found between asthma and AFS (P = 0.03). The mean Lund-Mackay score was 13.2 for non AFS and 18.8 for AFS patients (P =  < 0.01). Recurrence was seen in 11 (9.6 %) cases.

Conclusion The frequency of AFS in patients with nasal polyps was 23.7 % and the patients with AFS showed significantly higher mean Lund-Mackay score compared to non AFS patients.
