Superior canal BPPV, although rare, has downbeating vertical nystagmus. By contrast, horizontal BPPV has only horizontal nystagmus, which is either geotropic (fast component toward the ground) or apogeotropic (fast component away from the ground), depending on the variant. The nystagmus that occurs during posterior canal BPPV has characteristic upbeating and torsional components causing the superior pole of the eye to rotate toward the affected side in the head-hanging position. Short-lived nystagmus with associated vertigo results from gravity-induced movement of these particles. The current understanding of BPPV is that it occurs when otoconia become dislodged from the macula of the utricle and migrate down into the most gravity-dependent long arm of the posterior semicircular canal. 3 Following either, the condition is highly recurrent. The 2 fundamental maneuver variations are based on the techniques of Semont et al 2 and Epley. 1 Though it typically resolves over several months without any treatment, a clinician-guided maneuver can expedite the process.
