4.4 Conclusions
In this study, we further elaborated on the complications of ITD, mainly including tympanic membrane atrophy thinning and external auditory canal mycosis. By summarizing the characteristics of the above complications, 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. Mycosis of the external auditory canal is not a stubborn disease and can be cured by active treatment. Given the number of cases in our study is still relatively insufficient, the multi-center and large-sample data are needed to support the conclusion of the study.
