Differences in hearing recovery following intratympanic alone or intravenous dexamethasone with rescue intratympanic steroids for sudden sensorineural hearing loss: A randomised trial.

IT dexamethasone was safer than IV dexamethasone, and there was no evidence of a difference in hearing outcomes between IT dexamethasone and sequential IV plus IT treatments. It is necessary to make individualised treatment decisions according to the patient's condition.
