Abstract
Labyrinth of the inner ear consists of two parts: semicircular canals and vestibulum. Vestibular disorders predominantly associated with vertigo – the feeling of moving of the surrounding objects and oscillopsia. However, vertigo is a result of the damage of ampullar receptors in semicircular canals and their connections with vestibular nuclei in brainstem. At the same time the dysfunction of otoliths system is much more mysterious and unpredictable. Elaboration of new methods of objective assessment of vestibular system provides a wonderful opportunity of the analysis of different components of the peripheral vestibular system including saccular and utricular parts. As a result of such analysis, it was demonstrated that otolithic dysfunction is a common consequence of the most frequent vestibular disorders like Meniere’s disease, benign paroxysmal positional vertigo and vestibular neuritis. It is not clear yet what is the clinical presentation of otolithic dysfunction and how otolithic dysfunction influence the prognosis of common vestibular disorders. It is unknown whether isolated otolithic dysfunction exists, for example in patients with unspecific disequilibrium or dizziness.
