Abstract | INTRODUCTION:
Otomycosis, an infection of the ear canal by fungi, is prevalent in hot and humid weather. Nevertheless, there is not sufficient evidence for the effectiveness of different topical antifungal treatments. Tolnaftate, is a topical antifungal agent described to be effective in the treatment of otomycosis. Currently there are not sufficient studies that prove its efficacy. OBJECTIVES: MATERIAL AND METHODS: A controlled, randomized and open clinical trial included patients diagnosed with fungal external otitis who were treated with topical antifungals, randomized into two treatment groups: (1) clotrimazole cream; (2) tolnaftate solution. They were microscopically evaluated at one and two weeks of treatment to determine resolution of disease. Recurrence and complications were recorded. Demographic and clinical variables were collected and analyzed. Follow-up and final outcomes (absence of infection) were compared between groups. RESULTS: Forty eight patients were included, 28 in the clotrimazole group and 20 in the tolnaftate group. Spring was the weather most commonly associated with otomycosis, while otic manipulation was the risk factor more common in both groups. Predominant symptoms were itching and otic fullness. Aspergillus niger organism was isolated most frequently. Treatment with clotrimazole resulted in 75% resolution vs 45% resolution with treatment with tolnaftate at one week of treatment (p=0.007). The Tolnaftate treatment group demonstrated higher recurrence rates and treatment failures, 20% and 15% respectively. CONCLUSIONS:
