Abstract
-
Benign paroxysmal positional vertigo (BPPV) is a commonly presenting problem at the emergency department. Three types have been recognized based on the pathogenesis of BPPV. The first is posterior-canal canalolithiasis, the second is horizontal-canal canalolithiasis, and the last is horizontal-canal cupulolithiasis. With the first two types of BPPV, an otolith-repositioning manuever can be performed quickly at the bedside with rapid results, often providing much satisfaction to both patient and physician. However, in the case of horizontal-canal cupulolithiasis, no established repositioning maneuver existed until recently. In 2000, Jo et al. developed a new repositioning maneuver and reported excellent results. We report a case of BPPV horizontal-canal cupulolithiasis that immediately responded to the maneuver of Jo et al. and strongly recommend use of this repositioning maneuver at the emergency department.
