Succinct key points
  1. External auditory canal mycosis and tympanic membrane atrophy thinning can be observed in some patients after Intratympanic dexamethasone which has rarely been reported before. Herein, we summarized the characteristics of the particular complications we observed in our research center.
  2. In our study we have found two steroid-related side effects, including tympanic membrane atrophy thinning and external auditory canal mycosis.
  3. The steroid can make the tympanic membrane epithelial layer atrophy .
  4. Steroid can lead to immunesuppression, and the higher the concentration, the greater the chance of an opportunistic infection ,then the external auditory canal mycosis may occur.
  5. Clinicians can increase their understanding of these complications. Under the premise of ensuring the treatment effect, reducing the concentration of dexamethasone as far as possible can reduce the occurrence of fungal external auditory meatus.
