The results of transtympanic administration of 4 mg dexamethasone in 37 patients with moderate and severe Meniere's disease are presented. The endolymphatic hydrops was detected in all inner ear structures with predominant accumulation in vestibule and semicircular canals by MRI-visualization before therapy. After 1 month of 4 mg dexamethasone transtympanic therapy the hydrops degree decreased. Daily transtympanic administration of 4 mg dexamethasone for a month leads to reduction of vertigo attacks duration and expression in 92% of cases (follow-up period 24 months) and can be considered when conservative therapy is ineffective before destructive surgical interventions.
