Intratympanic gentamicin therapy for control of vertigo in unilateral Meniere's disease: a prospective, double-blind, randomized, placebo-controlled trial

Conclusions. Intratympanic application of gentamicin is a relatively safe and efficient treatment for the reduction of complaints of vertigo attacks associated with Meniere's disease. The treatment also reduces the severity of the perceived aural fullness. Objective. To investigate the effectiveness of intratympanic gentamicin treatment in patients with unilateral Meniere's disease. Subjects and methods. In a prospective, double-blind, randomized, placebo-controlled clinical trial subjects scored vertigo complaints, aural fullness and tinnitus, before, during and up to 1 year after treatment. Hearing loss was monitored with pure tone audiometry. Results. Gentamicin treatment resulted in a significant reduction of the score for vertigo complaints and the score for perceived aural fullness. A small increase in hearing loss (average 8 dB) was measured in the gentamicin group.
