Benign paroxysmal positional vertigo is a common disorder in Neurotology. This vestibular syndrome is characterized by transient attacks of vertigo, caused by change in head position, and associated with paroxysmal characteristic nystagmus. The symptoms result from movement of the free floating otoconia particles in the endolymph or their attachment to the cupulae of the semicircular canal. The diagnosis is essentially clinical and should be confirmed by performing diagnostic maneuvers. Treatment is based on the identification of the affected semicircular canal and performance of liberatory maneuvers or repositioning of free floating particles of otoliths. The effectiveness varies from 70 to 100%.
良性阵发性位置性眩晕是神经耳科学中的一种常见病症。这种前庭综合征的特征是由头部位置变化引起的短暂性眩晕发作，并伴有阵发性特征性眼球震颤。症状是由内淋巴中自由漂浮的耳石颗粒移动或它们附着于半规管壶腹所致。诊断主要基于临床，应通过进行诊断性手法来确诊。治疗基于确定受影响的半规管，并实施解脱手法或重新定位耳石的自由漂浮颗粒。有效率在70%至100%之间。
