Objective:
To investigate the efficacy of intratympanic dexamethasone injections (IDI) for 15 patients with intractable Meniere's disease (MD).

Result:
The 15 patients were followed up for 18 months (average). Complete relief of vertigo was maintained in 10 cases, improved in 2 case, injection wos repeated 3 patients with recurrent vertigo resulted in control of vertigo. Tinnitus disappeared in 5 cases, reduced in 5 cases, unchanged in 5 cases. Hearing was improved in 10 cases, unchanged in 5 cases.
