Surgical management for benign paroxysmal positional vertigo of the superior semicircular canal.

Benign paroxysmal positional vertigo of the superior semicircular canal is a rare form of BPPV. It accounts for 1% to 3% of cases. The characteristic nystagmus is positional, down-beating, with a torsional component elicited by the Dix-Hallpike maneuver. Symptoms of superior semicircular canal BPPV often resolve spontaneously; however, it can be refractory to repositioning maneuvers. Surgical management is described for posterior semicircular canal BPPV. To date, however, there is only one reported case of surgical management for superior semicircular canal BPPV. Here we show video documentation of positional, down-beating nystagmus and describe a case of superior semicircular canal BPPV requiring canal occlusion with successful resolution of symptoms.
