@entity364 of the ear are mostly described as mycoses of the auditory canal. The aim of our investigations was to find out how fungi colonize the ear in immunocompetent @entity1 . In the years from 1993 to 2000, 128 @entity1 suspected of having @entity22815 were examined. Of these 115 @entity1 suffered from @entity102 media with persisting tympanum perforation and @entity2972 . A further 13 @entity1 had clinical signs of @entity2346 externa only. In 54 out of 139 samples, fungi were found in the auditory canal, in five on the tympanic membrane, and in five in the middle ear. Two-thirds were isolated as moulds and one-third as @entity375 . Dominating species were @entity11150 and @entity7409 . Samples of 15 @entity1 suspected of having @entity2267 or @entity3540 were examined histologically. Fungal hyphae were observed in the @entity2172 and/or between horny lamellae of @entity3540 in 4 @entity1 . In the middle ear of immunocompetent @entity1 @entity1127 was detected with increased production of mucus, which probably promotes the colonization with pathogenic fungi as in the middle ear just like in the auditory canal.
