Résumé
Human amniotic tissue previously treated with sodium hypochlorite and ethyl alcohol and stored in pure glycerol was employed to repair total and partial tympanic membrane perforations in 43 patients who underwent tympanoplasty or tympano-mastoidectomy. Follow-up varied from nine to 54 months. Closure of the perforation was obtained in 35 patients (81.4 per cent). Success rate was higher in tympanoplasty (84.8 per cent) than in tympanomastoidectomies (70 per cent). Functional improvement in hearing level was obtained in 65.7 per cent of the cases. In 25.7 per cent the hearing levels were unchanged and in 8.57 per cent they became worse. It was concluded that human amniotic tissue is an adequade material for tympanic membrane repair.

Em vista da escassez de publicacoes sobre otomicoses no Brasil, foi projetada uma pesquisa para conhecer a incidencia, caracteristicas clinicas, fatores predisponentes e agentes etiologicos da micose. Durante um ano, 22 casos suspeitos foram estudados, 20 dos quais corresponderam a otomicoses. As especies mais frequentemente isoladas foram Aspergillus niger (35 por cento) e Candida albicans (20 por cento). O genero Aspergillus representou 75 por cento dos isolamentos. Os sinais clinicos mais comuns foram prurido e hiperemia (70 por cento), otalgia (65 por cento), hipoacusia (50 por cento). Falta de cerumen (70 por cento), otite cronica (30 por cento), antibioticoterapia previa e eczema (25 por cento) foram os fatores predisponentes mais relevantes.
