Abstract:
ObjectivesOur objective was to study the efficacy and safety of intratymapanic dexamethasone (ITD) for treating in Méniere's disease in southern China.MethodsA total of 124 patients with Méniere's disease were randomly divided into 2 groups: ITD group (n = 62) and intratympanic lidocaine (ITL) group (n = 62). The ITD group was further randomly divided into 2 groups based on dexamethasone dosage: ITD1 (2 mg/ml) (n = 31) and ITD2 (5 mg/ml) group (n = 31). Symptom alleviation and complications were recorded after every treatment.ResultsVertigo was improved in 65% of patients who received ITD compared with 55% of patients who received ITL patients (P < .05). Three patients in the ITD2 group had from otomycosis, and 2 of these patients had a perforation; no tympanic membrane perforation was observed in the ITL and ITD1 group.ConclusionsCompared with lidocaine, dexamethasone is more effective in alleviating vertigo, and a lower concentration of dexamethasone can reduce the occurrence of complications.
