Abstract :

Otomycosis is a fungal infection, which leads to a damage of the external auditory canal. The objective was to study the epidemiological and clinical aspects of otomycosis at Sourô SANOU University Hospital in Bobo–Dioulasso. A prospective study was performed in the Department of Oto Rhino Laryngology and the Department of Parasitology–Mycology. Using sterile swabs under otoscopic examination allowed collecting samples. Germ tube Test, Chromogenic Medium and Latex Reagents for Rapid identification Testwere performed identifying yeast fungi. Filamentous fungi were identified on macroscopic and microscopic criteria. Out of 216 patients with infectious otitis, 159 showed a positive culture in 73.6% (159/216). The prevalence of otomycosis was 59.3%. A female predominance was observed in 53.5% with a sex ratio of 0.9. The age group from 0 to 20 years old was mostly involved in 49,7% of cases followed by the age group from 21–40 years old (22%). The most commonly isolated species were Candida albicans (20.9%), Aspergillus niger (20.3%), Aspergillus fumigatus (19%), Aspergillus flavus (16%), and Candida non–albicans (7.9%). Management of otomycosis should include clinical as well as mycological diagnosis and information for changing behavior patterns leading to infection.
