Especially after prolonged antibiotic ototopic therapy otomycosis is not ra
re. An inoculation of fungi into the tympanic cavity however may have serio
us sequelae. Therefore an eradication of fungi from the external auditory c
anal is imperative before surgery. In addition to thorough cleaning of the
outer ear canal antimycotic preparations are recommended in treating otomyc
osis. However, all of the commercially available ear drops contain ototoxic
agents. In the case of defects of the tympanic membrane a damage of the in
ner ear may result. Alternatively, we suggest an aqueous solution of Micona
zol 0,5%.
