使用视频头脉冲测试 (vHIT) 和热量测试评估良性阵发性位置性眩晕 (BPPV) 的半规管功能。我们回顾性分析了 39 名特发性 BPPV 患者，他们接受了 vHIT 和热量测试。 21 名患者患有后部 BPPV (p-BPPV)，18 名患者患有水平 BPPV (h-BPPV)。在 vHIT 中分析前庭眼反射 (VOR) 增益和矫正性眼跳 (CS)，并在热量测试中计算耳管麻痹 (CP)。 p-BPPV 中后半规管受影响侧的平均 VOR 增益为 0.75±0.28，明显小于对侧 (0.93±0.24，p = .00738)。另一方面，受影响侧和对侧之间 h-BPPV 水平管的 VOR 增益没有显着差异 (p = .769)。在 p-BPPV (p = .111) 或 h-BPPV (p = .0599) 中，受影响的根管和对侧根管之间的 CS 存在率没有显着差异。 h-BPPV 患者的平均 CP 值 (43.5±31.3%) 显着高于 p-BPPV 患者 (22.2±22.9%；p = .0184)。 p-BPPV 中受影响管中 vHIT 的 VOR 增益显着小于对侧管中的 VOR 增益，但 h-BPPV 中则不然。与 p-BPPV 相比，h-BPPV 中受影响管的热量反应明显更大程度地降低。这些结果表明，BPPV 对半规管功能的影响不同，具体取决于所涉及的半规管。 p-BPPV 中受影响管中 vHIT 的 VOR 增益显着小于对侧管中的 VOR 增益，但 h-BPPV 中则不然。与 p-BPPV 相比，h-BPPV 中受影响管的热量反应明显更大程度地降低。这些结果表明，BPPV 对半规管功能的影响不同，具体取决于所涉及的半规管。
To assess semicircular canal function in benign paroxysmal positional vertigo (BPPV) using the video head impulse test (vHIT) and caloric test. We retrospectively reviewed 39 patients with idiopathic BPPV who underwent both vHIT and the caloric test. Twenty‐one patients had posterior BPPV (p‐BPPV) and eighteen had horizontal BPPV (h‐BPPV). Vestibulo‐ocular reflex (VOR) gain and corrective saccades (CS) were analyzed in vHIT and canal paresis (CP) was calculated in the caloric test. The mean VOR gain of the posterior canal in p‐BPPV was 0.75 ± 0.28 on the affected side, which was significantly smaller than that on the contralateral side (0.93 ± 0.24, p = .00738). On the other hand, there were no significant differences in the VOR gain of the horizontal canal in h‐BPPV between the affected and the contralateral sides (p = .769). The rates of the presence of CS were not significantly different between the affected canal and the contralateral canal either in p‐BPPV (p = .111) or h‐BPPV (p = .0599). The mean CP value in h‐BPPV patients (43.5 ± 31.3%) was significantly higher than that in p‐BPPV patients (22.2 ± 22.9%; p = .0184). The VOR gain of vHIT in the affected canal was significantly smaller than that in the contralateral canal in p‐BPPV, but not in h‐BPPV. The caloric responses of the affected canal are reduced to a significantly larger extent in h‐BPPV compared to p‐BPPV. These results suggest that BPPV affects the semicircular canal function differently depending on which semicircular canal is involved. The VOR gain of vHIT in the affected canal was significantly smaller than that in the contralateral canal in p‐BPPV, but not in h‐BPPV.
