Wang D, et al. - Authors evaluated the outcomes of intratympanic injection of dexamethasone after failure of intravenous prednisolone in simultaneous bilateral sudden sensorineural hearing loss (SSNHL). They retrospectively evaluated the cases of simultaneous bilateral SSNHL treated in their hospital from March 2007 to March 2018. For simultaneous bilateral SSNHL, intratympanic injection of dexamethasone after failure of intravenous prednisolone therapy was a better choice vs traditional intravenous prednisolone therapy. The effective rate was significantly different between the two groups.
