Summary

Positional vertigo is a very common symptom seen in ENT clinics, as well as in A&E and general and family practice. The most common cause of this condition is Benign Paroxysmal Positional Vertigo, caused by the displacement of otoliths (calcium carbonate crystals, Fig. 1) from the utricle into the semicircular canals, with the posterior semicircular canal most commonly affected.
