New dimensions of benign paroxysmal positional vertigo.


Twenty-nine patients who demonstrated the classic nystagmus of benign paroxysmal positional vertigo in the provocative, ear-down position had a high incidence of concurrent symptoms. These included vertigo provoked by arising, bending over, head rotation, linear acceleration, and vertical oscillation. Some have not been reported previously in relation to this syndrome. Elimination of both concurrent and classic symptoms via singular neurectomy in nine patients indicates a common pathophysiologic mechanism, probably involving cuplolithiasis in the posterior semicircular canal. These concurrent symptoms should be considered part of the syndrome.
