After the canal has been partially debrided (middle), granular inflammatory changes in the underlying epithelium are revealed by the appearance of spontaneous bleeding. The purulent de
bris has now been removed (right), and the tympanic membrane over the short process of the malleus and the malleus handle shows a granular myringitis. This was produced by the invasion of the superficial layer of the tympanic membrane by Aspergillus niger.
Treatment includes careful microdebridement and the application of specific antimycotic topical agents. In the case of a mixed bacterial and fungal infection, alternating treatment with topical antibiotics and topical antimycotic agents may be required. |
