Abstract: Introduction: Otomycosis is a sub-acute or chronic superficial fungal infection of the external auditory canal. It is found throughout the world but is more prevalent in warm, humid, dusty environment. The commonly found causative fungi include Aspergillus and Candida species. The aim of this study was to determine the prevalence of fungal agents, gender wise distribution and predisposing factors involved in otomycosis Material and Methods: A total of 100 cases of symptomatic patients suspected to be of otomycosis were studied, during the period of May 2011 to December 2011. Ear discharge specimens were collected on two sterile cotton swabs. Direct examination of the specimen was carried out by Gram stain and 10% KOH mount. All specimens were inoculated on Sabouraud Dextrose Agar. Identifications of fungi were done as per standard protocol. Results: Out of 100, fungal isolates were found in 86 (86%) specimens. Most common fungal isolate was Aspergillus niger (45%) followed by A. flavus (22%), Candida albicans (21%) and A. fumigatus (12%). Ear ache (55%) has been found as the most common presenting symptom. It is found to be more prevalent in males (65%). Improper self cleaning (64%) has been found as major predisposing factor of otomycosis. Conclusion: In present study A. niger (45%) is the major etiological agent causing Otomycosis.
