Vestibular neurectomy effective for Meniere disease

For patients with Meniere disease (MD), vestibular neurectomy is effective, resolving vertigo episodes and resulting in hydrops regression, according to a study published online July 30 in Acta Neurologica Belgica.

Cochlea

The cochlea is the auditory portion of the inner ear. It is a spiral-shaped cavity in the bony labyrinth, making 2.5 turns around its axis, the modiolus. A core component of the cochlea is the Organ of Corti, the sensory organ of hearing, which is distributed along the partition separating fluid chambers in the coiled tapered tube of the cochlea.

The name is from the Latin for snail shell, which is from the Greek κοχλίας kokhlias ("snail, screw"), from κόχλος kokhlos ("spiral shell") in reference to its coiled shape; the cochlea is coiled in most mammals, monotremes being the exceptions.
