Benign Paroxysmal Positional Vertigo (BPPV) is the most common vestibular disorder, resulting from detached otoliths that migrate to one of the semicircular canals - canalolithiasis - or one of the cupulas - cupulolithiasis. The present study is related to lateral canal BPPVs, which may be either geotropic or apogeotropic. The geotropic variant of lateral semicircular canal benign paroxysmal positional vertigo (LC-BPPV) is attributed to free floating particles in the posterior arm of the lateral semicircular canal. To verify the possibility of employing the Zuma repositioning maneuver, with a brief modification, as an alternative treatment for geotropic LC-BPPV. Seven patients with geotropic LC-BPPV were enrolled and treated with the Zuma modified maneuver. Patients were reevaluated 1 hour after a single maneuver, to confirm the resolution of vertigo and positional nystagmus. All seven patients achieved immediate resolution of vertigo and positional nystagmus as measured 1 hour after the application of the maneuver. The Zuma modified maneuver was effective for geotropic LC-BPPV after a single application. The use of the Zuma maneuver for both apogeotropic and geotropic LC-BPPV may simplify the treatment of these patients.
良性阵发性位置性眩晕（BPPV）是最常见的前庭疾病，由脱落的耳石移位至半规管之一（管结石症）或壶腹嵴之一（壶腹结石症）引起。本研究与水平半规管BPPV相关，其可能为向地性或背地性。水平半规管良性阵发性位置性眩晕（LC-BPPV）的向地性变体归因于水平半规管后半规管内的自由漂浮颗粒。 为验证采用经简短修改的祖马复位手法作为向地性LC-BPPV替代治疗方法的可能性。 纳入7例向地性LC-BPPV患者，采用改良的祖马手法进行治疗。单次手法治疗1小时后对患者进行重新评估，以确认眩晕和位置性眼震是否消失。 所有7例患者在手法治疗1小时后测量时均立即出现眩晕和位置性眼震消失。 改良的祖马手法单次应用后对向地性LC-BPPV有效。将祖马手法用于背地性和向地性LC-BPPV可能会简化这些患者的治疗。
