Control of vertigo in Ménière's disease by intratympanic dexamethasone.

OBJECTIVE

The main objective was to assess the efficacy of intratympanic dexamethasone injection in controlling vertigo in unilateral Ménière's disease refractory to medical treatment.

MATERIALS AND

METHODS

A retrospective study included 25 patients with disabling unilateral Ménière's disease, defined according to the American Academy of Otorhinolaryngology-Head and Neck Surgery (AAO-HNS) criteria. Patients received intratympanic dexamethasone during the monitoring period. Control of vertigo was classified according to AAO-HNS vertigo control index, at 6 months, 1 year, and 2 years after treatment initiation. Complications and progression of hearing were also assessed.

RESULTS

Satisfactory control (class A or B) was obtained in 92% of patients (n=23/25) at 6 months, 68% (n=17/25) at 1 year, and 70% (n=16/23) at 2 years. There was no worsening of hearing in those patients who were well-controlled by this therapeutic strategy. No local or systemic complications were observed during follow-up.

CONCLUSION

Dexamethasone is part of the management strategy for patients with Ménière's disease refractory to conventional treatment, implemented before destructive treatment. It achieves control of vertigo in 70% of patients at 2 years.
