Abstract

Introduction: Otomycosis is fungal infection of external and middle ear. These are prevalent in warm and humid climate which may even lead to Hearing loss and perforation of ear drum. This study was done to assess the etiological agent(s) and their antifungal sensitivity.

Aims and Objectives: 1. To identify the causative organisms of Otomycosis. 2. Study of antifungal susceptibility pattern.

Methodology: 50 patients were studied in a period of one year. 1. Examination of Potassium hydroxide mount (10%) of the sample. 2. Culture on Sabouraud’s Dextrose Agar and Sabouraud’s Dextrose Chloramphenicol Agar. 3. Examination of Lactophenol Cotton Blue mount and appropriate biochemical test.

Result: In one year duration study was conducted on 50 suspected samples of otomycosis patient. 46 samples showed positive result, Aspergillus fumigatus (n = 17,34%) was commonest followed by Candida albicans (n = 11,22%), Aspergillus niger (n = 10, 20%), and Penicillum species (n = 6, 12%). Candida species was found sensitive to Itraconazole, Nystatin and resistant to Amphotericin- B, Fluconazole. Females (64%) were affected more than Males (36%) and disease was commonly reported in middle age group. 

Discussion: In this study on 50 patients of otomycosis, 46 were positive and Aspergillus fumigatus was commonest isolate followed by Candida species and Aspergillus niger.

Conclusion: 1. Aspergillus fumigatus affecting otomycosis followed by Candida species and Aspergillus niger. 2. Antifungal sensitivity was performed.
