| Research Abstract |
We have studied the natural course of positional vertigo in patients with the apogeotropic variant of horizontal canal type of benign paroxysmal positional vertigo(AH-BPPV) and showed the natural course of AH-BPPV is not refractory. In patients with benign paroxysmal positional vertigo, when the axis of eye rotation during abnormal nystagmus is perpendicular to the plane of semicircular canal, the prognosis is good, and when the axis is not perpendicular to the plane of semicircular canal, the prognosis is not good.
