Meniere’s disease is traditionally diagnosed using clinical indicators according to the criteria of the American Academy of Otolaryngology – Head and Neck Surgery of 1995 and the new criteria of the Barany Society 2016 [4, 5]. However, these anamnestic-based diagnostic criteria are intrinsically imprecise and cause diagnostic false positive and negative results. This has traditionally made objective assessment of treatment modalities almost impossible [6]. MRI hydrops imaging is able to identify patients with definite hydrops with a sensitivity and specificity of more than 90% and may be helpful in the reassessment of the efficacy of treatments with a traditionally poor evidence base, for example, sac surgery.

Fig. 5. Endolymphatic hydrops on the left side visualized on a contrast-enhanced 3D-FLAIR image: Long white arrow points to confluent signal-void area in the left vestibulum (hydrops grade 1). Shorter white arrow points to hydropic scala media in the left cochlea (hydrops grade 1). Right ear is normal. Very short white arrowheads show normal anatomy of the sacculus and utriculus on the right side.
