Abnormal morphology of the vestibule of the inner ear

What it means

A morphological abnormality of the vestibule, the central part of the osseous labyrinth that is situated medial to the tympanic cavity, behind the cochlea, and in front of the semicircular canals.

The vestibular system consists of five distinct components, three semicircular canals that are sensitive to angular acceleration and two otolith organs that are sensitive to linear acceleration.
