Abstract
OBJECTIVE: The aim of this study was to assess the efficacy of a single high dose intratympanic (IT) dexamethasone (DEX) as salvage therapy for idiopathic sudden sensorineural hearing loss (ISSNHL) after unsuccessful treatment with oral corticosteroid (CS).
MATERIALS AND METHODS: This was a prospective open-label study of 59 patients treated with IT DEX after systemic CS therapy has failed. All patients received high dose (24 mg/mL) IT DEX in a single injection through myringotomy.
RESULTS: Of the 59 patients, 40.7% showed improvement in their mean pure tone average (PTA) with IT DEX (p=0.005). The difference in the mean PTA after oral CS treatment only from baseline was not statistically significant (p=0.074). The time from onset of hearing loss to the start of therapy was significantly associated with the outcome (p=0.03).
CONCLUSION: We determined that high dose IT DEX as salvage therapy was beneficial when the primary treatment with oral CS had failed. An early start of the treatment significantly influenced the improvement of hearing.
