Equilibrium is the required state of a body by opposing and equal forces, it is the maintenance of the body position appropriate to each circumstance, both in static and dynamic condition. The posterior labyrinths regulate these forces to a great extent, and normality is based on the equality of their tones. They are made up of the semicircular ducts and the membranous vestibule (constituted by the utricle and the saccule). Semicircular ducts can be examined through rotational or bicalorical vestibular tests, otolithic organs (utricle and saccule) because of their anatomical location are limited in the study of their functions, however, there is a neurophysiological test (evoked vestibular myogenic potential) capable of exploring the function of the saccule and inferior vestibular nerve, which takes advantage of the ability of the saccule to be stimulated with high sound intensity at different frequencies.

Keywords : Myogenic vestibular evoked potentials; sacculus.
