[Otomycosis: a microbiological study of 147 cases of otitis externa].

An accurate and systematic myco- and bacteriological appraisal of each case, should comport the lowering of wrong diagnosis and also therapeutic failures in those patients. The target of the AA. is to verify the frequency and the identification as well, of bacteria and/or fungi, unique or in association, responsible for the otitis. And the objective is to start with the most appropriate treatment in spite of the laboratory answer and also to schedule a laboratory protocol to follow in suspected cases of otomycosis.
