Horizontal semicircular canal site pathology of benign paroxysmal positional vertigo demonstrating three types of nystagmi on positional test were studied. We have attempted to design a protocol for its diagnosis and treatment.
320 patients of HSC-BPPV were subjected to two types of positional tests. Of these, patients with bilateral steady apogeotropic nysatgmus were treated with VAV modification of Semont's maneuver. Patients with unsteady or changing apo/geotropic signs were converted into steady geotropic ones by repetitive positional tests; followed by barbecue maneuver with forced prolong positioning.
Overall 88% of patients had a total recovery. 92% of patients with geotropic nystagmus showed no symptoms after second maneuveral sitting. 85% of patients with apogeotropic nystagmus recovered fully after third maneuveral sitting.
Correct identification of subtypes of HSC-BPPV is based on provoked nystagmus by positional tests. After locating the site and side on the basis of nystagmic pattern, physician can apply the appropriate PRM.

研究良性阵发性位置性眩晕（BPPV）的水平半规管管结石症（HSC-BPPV）在变位试验中呈现三种类型眼震的病理特征。我们尝试设计了一种针对其诊断和治疗的方案。
对 320 例 HSC-BPPV 患者进行了两种类型的变位试验。其中，双侧水平向持续向地性眼震的患者采用 Semont 手法的 VAV 改良版进行治疗。对于无规律或变化的向地/离地性眼震的患者，通过重复变位试验将其转变为稳定的向地性眼震，然后进行强制延长体位的烧烤手法。
总体而言，88%的患者完全康复。第二个体位操作后，92%的具有向地性眼震的患者无症状。第三个体位操作后，85%的具有离地性眼震的患者完全恢复。
根据变位试验诱发的眼震正确识别 HSC-BPPV 的亚型。基于眼震模式确定位置和侧别后，医生可以应用适当的 PRM。
