摘要
目的探讨水平半规管良性阵发性位置性眩晕（benign paroxysmal positional vertigo,BPPV）的临床特点。方法回顾性分析56例水平半规管BPPV患者的临床表现及眼震电图特征,通过体位试验确诊BPPV后,水平向地性眼震者以Barbecue翻滚法复位治疗,水平背地性眼震者经左右侧头训练后再同法复位,并限制体位。结果 56例患者中,平卧侧头试验见水平向地性眼震者41例,潜伏期为2.5±1.3s,其中5例患者无明显潜伏期,眼震持续时间22.9±16.4s,2例持续时间≥60s;诱发出水平背地性眼震者15例,潜伏期为3.7±3.1s,眼震持续时间67.2±17.7s,其中2例持续时间≤60s。41例水平向地性眼震者中39例1次复位成功,首次复位治疗成功率为95.12%（39/41）,其中2例眼震持续时间〉60s的患者均一次复位成功;有2例复位不成功。15例水平背地性眼震患者中,2例在首次左右侧头训练时即见眼震转化为水平向地,3例在2~4次随访时转化为水平向地;眼震转化后再行平卧侧头试验表现为,转向起初眼震为水平背地较弱侧时,其水平向地性眼震更明显,且眼震速度明显增快、潜伏期明显缩短。结论在水平半规管BPPV患者的复位治疗过程中,翻滚复位法结合左右侧头训练及体位限制有助于复位成功。
Objective To explore the clinical features of horizontal semicircular canal benign paroxysmal positional vertigo.Methods The clinical manifestations of 56 patients with horizontal semicircular canal benign paroxysmal positional vertigo from July 2012 to December 2013 were retrospectively analyzed.Results Among 56 patients,41patients showed geotropic nystagmus in head rolling test with a mean latency period of 2.5±1.3sand a mean duration period of 22.9±16.4s.15 patients showed geotropic nystagmus in head rolling test with a mean latency period of 3.7±3.1sand a mean duration period of 67.2±17.7s.We applied Barbecue maneuver to the patients with geotropic nystagmus after the head shaking maneuver was administered to the patients with apogeotropic nystagmus.Conclusion The incidence rate of horizontal semicircular canal benign paroxysmal positional vertigo was higher than that expected.The Barbecue maneuver was applied to patients with geotropic nystagmus.In addition to the patients with apogeotropic nystagmus,the head shaking maneuver should be performed firstly and then followed by Barbecue maneuver.
