High-Dose Glucocorticoids for Sudden Hearing LossThis trial compared courses of high-dose intravenous prednisolone or high-dose oral dexamethasone versus standard-dose oral prednisone in adults with idiopathic sudden sensorineural hearing loss. At 30 days, systemic high-dose glucocorticoid therapy was not superior to a lower-dose regimen with respect to change in hearing threshold, and it was associated with a higher risk of side effects.
