The treatment of benign paroxysmal positional vertigo is designed according to the theory of crestal calculus and canal calculus. The purpose is to make the stones adhering to the crestal apex or the small dense particles floating freely in the lymph of the lumen of the long arm of the semicircular canal to be dislodged from the parietal cap or to enter the ellipsoidal bursa through the common foot or the horizontal semicircular canal foot by sequential changes of head position, so that the crestal apex of the semicircular canal and the lymph of the lumen of the long arm of the semicircular canal canal can be restored to normal movement. The normal motion of the lymph in the lumen of the semicircular canal is restored, the causative factors are eliminated, and the symptoms are relieved. Many patients can recover by repositioning. However, this treatment must be done by professionals and not by laymen, otherwise, serious consequences may occur. Commonly used methods include the Epley’s otolith repositioning technique, the modified Semont technique and the Barbecue tumbling method.
