Benign paroxysmal positional vertigo (BPPV) is the most common cause of peripheral vestibular vertigo. It is caused by free-floating otoconia moving freely in one of the semicircular canals (canalolithiasis) or by otoliths adhered to the cupula (cupulolithiasis). The posterior canal is the most common canal affected, followed by the lateral canal. Diagnosis of the side affected is critical for successful treatment; therefore, suppressing visual fixation is essential to examination of these patients' eye movement. On the basis of our experience, we have adopted the Zuma maneuver and the modified Zuma maneuver for both apogeotropic and geotropic variants of lateral canal BPPV. Knowledge of the anatomy and pathophysiologic mechanisms of the semicircular canals is essential for correct management of these patients. Hence, using a single maneuver and its modification may facilitate daily neurotological practice.
良性阵发性位置性眩晕（BPPV）是周围性前庭性眩晕最常见的病因。它是由自由漂浮的耳石在半规管之一中自由移动（管结石症）或由附着于壶腹嵴的耳石（壶腹嵴顶结石症）引起的。后半规管是最常受累的半规管，其次是外半规管。确定患侧对于成功治疗至关重要；因此，抑制视觉固定对于检查这些患者的眼球运动至关重要。根据我们的经验，我们已将祖马手法和改良祖马手法应用于外半规管BPPV的背地性和向地性变体。了解半规管的解剖结构和病理生理机制对于正确管理这些患者至关重要。因此，使用单一手法及其改良方法可能会促进日常神经耳科学实践。
