【摘要】：目的分析良性阵发性位置性眩晕(BPPV)患者变位实验中眼震的参数特征,探讨其临床意义和产生机制。方法回顾性分析398例BPPV患者,应用视频眼震电图记录变位实验诱发的眼震,分析比较后半规管BPPV(PC-BPPV)和水平半规管BPPV(HC-BPPV)变位实验各头位眼震方向、潜伏期和持续时间等参数特点。结果 BPPV患者398例,其中PC-BPPV 290例,占73.1%(290/398),271例诱发出向地、旋转、向上型眼震,平均潜伏期(26.36±18.70)s,眼震持续时间平均(10.88±8.89)s;HC-BPPV 103例,占25.8%(103/398),76例诱发出水平向地性眼震,平均潜伏期(0.67±0.68)s,眼震持续时间平均(25.34±20.12)s,24例HC-BPPV水平离地性眼震患者平均潜伏期(3.59±2.01)s,平均持续时间(52.30±40.21)s。与PC-BPPV相比,水平向地性HC-BBPV在潜伏期、眼震持续时间差异具有统计学意义(t=21.13和8.89,P=0.007和0.002);水平离地性HC-BPPV在潜伏期差异无统计学意义(t=0.08,P=0.945),而在持续时间差异具有统计学意义(t=6.10,P=0.003)。结论在变位实验中,PC-BPPV眼震潜伏期长于向地性HC-BPPV,不一定长于水平性HC-BPPV,但持续时间短于所有类型HC-BPPV。
[Abstract]:Objective to investigate the clinical significance and mechanism of nystagmus in patients with benign paroxysmal positional vertigo (BPPV). Methods A total of 398 patients with BPPV were analyzed retrospectively. The nystagmus induced by transposition experiment was recorded by video nystagmography, and the characteristics of nystagmus, latency and duration were compared between posterior semicircular canal BPPV-PC-BPPV) and horizontal semicircular canal BPPV-HC-BPPV-HC-BPPV. Results among 398 patients with BPPV, 290 were PC-BPPV, accounting for 73.1% 290 / 398,271 cases of nystagmus were induced to face, rotate and upward nystagmus, the average latency was 26.36 卤18.70 s, and the mean duration of nystagmus was 10.88 卤8.89 sHC-BPPV in 103 cases, accounting for 25.883% 39876 cases of horizontal nystagmus. The mean latency was 0.67 卤0.68 Ms, the mean duration of nystagmus was 25.34 卤20.12 Ms, the mean latency of HC-BPPV was 3.59 卤2.01g / s, the mean duration was 52.30 卤40.21s. Compared with PC-BPPV, horizontal HC-BBPV had significant difference in latency and duration of nystagmus, but there was no significant difference in incubation period between horizontal off-ground HC-BPPV and PC-BPPV, but there was significant difference in the duration of HC-BPPV between two groups, but there was a significant difference in the duration of HC-BPPV between horizontal HC-BPPV and PC-BPPV, but there was no significant difference in latency between horizontal HC-BPPV and PC-BPPV, but there was a significant difference in the duration of nystagmus between horizontal HC-BPPV and horizontal off-ground HC-BPPV. Conclusion the latency of PC-BPPV is longer than that of ground-oriented HC-BPPVs, not necessarily longer than that of horizontal HC-BPPVs, but the duration of PC-BPPV is shorter than that of all types of HC-BPPVs.
