The investigation of the fungal etiologies of otomycoses is a rare occurrence in Senegal. The present study aspires to ascertain the profile of these mycoses within the confines of Ziguinchor. Conducted from 3 February 2021 to 31 August 2022, this retrospective descriptive study encompassed a total of 82 patients presenting with clinically suspected otomycosis within the otolaryngology (ENT) department of the Ziguinchor Peace Hospital (ZPH). In this study, two samples were collected from the external auditory canal (EAC) of each patient using sterile swabs. These samples were first observed by direct microscopy and then cultured at 30 °C on Sabouraud chloramphenicol with or without cycloheximide. The identification of the isolates was based on their macroscopic, microscopic, and physiological characteristics. The mycological examination was positive in 70 patients, with a prevalence of 85.37%. The most prevalent fungal isolates were <i>Aspergillus section Nigri</i> (30%), <i>Aspergillus section Flavi</i> (20%), and <i>Candida albicans/Candida dubliniensis</i> (10%). Of the clinical signs examined, auricular pruritus (<i>p</i> = 1.7033 × 10<sup>−6</sup>) was the only one to demonstrate a positive correlation with the onset of otomycosis. These results indicate that fungal agents play a significant role in the pathogenesis of otitis externa, underscoring the importance of mycological diagnosis in ensuring optimal patient management.
