Abstract

Background: Otomycosis is a fungal infection of the external ear with bothersome symptoms. The aim of this study was to evaluate the prevalence of fungal agents, predisposing factors and characteristics of patients.

 

Methods: Between May 2008 and April 2010, 171 patients with clinical suspicion of otomycosis were enrolled and the samples from their external ear were examined for any mycological infection.

 

Results: Otomycosis was confirmed after mycological diagnosis in 69% of clinically suspected patients. The highest incidence of otomycosis was in autumn and in patients aged 21-40 years old. Working in dry dusty environment was a major predisposing factor. Pruritus was the most common symptom. Aspergillus flavus was the most common fungus in otomycosis followed by A. niger, Candida albicans, A. fumigatus, A. nidulans and C. parapsilosis.

 

Conclusion: Clinical suspicion of otomycosis is important to prevent unnecessary use of antibiotics. Etiology of fungal pathogens in dry dusty regions is not similar to hot humid areas and this needs to be considered in future susceptibility tests and treatment of patients with otomycosis.
