[Presumption diagnosis: otomycosis. A 451 patients study].

Otomycosis is a common disease. We try to analyze the causative factors for otomycosis in our environment. Our study includes 451 patients with a presumed diagnosis of otomycosis. The patients were included by ear, nose and throat specialist and general doctors; the diagnosis was confirmed in 24.43% and 16.16% respectively. The most common fungal pathogen found was Aspergillus spp. and Candida sp. The high frecuency of Aspergillus Niger may be because of the diferent ways of gathering samples. The abundance of Candida parapsilosis in the samples that came from general doctors may be because the inadequate treatment with topic antibiotics contributes fungal proliferation. We conclude that the causative factors for otomycosis could be avoided or treated. Treatment with antifungal agents is not enought to ensure complete cure, an furthermore the treatment should be aimed to restore the physiology of the external auditory cannal.
