摘要
目的探讨良性阵发性位置性眩晕的临床特征。方法回顾性分析2009年8月至2011年7月诊治的326例良性阵发性位置性眩晕患者的临床特征，并对不同类型的良性阵发性位置性眩晕作比较。结果良性阵发性位置性眩晕女性多见，50—60岁为发病高峰段，潜伏期为（1．52±1．22）s，无明显潜伏期患者43例（13．2％），眩晕发作持续时间中位数为10s，持续时间〈60s患者312例（95．7％），持续时间60～180s患者13例（4．0％）；后半规管良性阵发性位置性眩晕与水平半规管良性阵发性位置性眩晕相比，潜伏期较长，分别为（1．74±1．21）s、（0．96±1．06）s（t=5．546，P〈0．01），而在性别构成、病程、眩晕持续时间上均无明显差异；后半规管壶腹嵴顶耳石症患者年龄较后半规管耳石症患者更年轻，持续时间更长；与水平半规管耳石症相比，水平半规管壶腹嵴顶耳石症患者潜伏期、持续时间均较长，年龄更大。结论良性阵发性位置性眩晕以后半规管受累常见，与水平半规管相比，后半规管良性阵发性位置性眩晕潜伏期更长；水平半规管壶腹嵴顶耳石症与水平半规管耳石症相比年龄更大，潜伏期、持续时间更长。
Objective To explore the clinical features and repositioning maneuver effects of benign paroxysmal positional vertigo （BPPV）. Method The clinical features of 326 patients with BPPV from August 2009 to July 2011 were analyzed retrospectively. Different types of BPPV were compared. Results BPPV was more common in female and the peak period of onset was between the ages of 50 and 60. The average latency of vertigo attack was （ 1.52 ± 1.22） s and 43 patients （ 13.2% ） had no obvious latency. The median duration of vertigo attack was 10 s, with less than 60 s in 312 patients （95.7%） and between 60-180 s in 13 patients （4. 0% ）. The latency of vertigo attack of posterior semicircular canal-BPPV （ （1.74±1.21 ） s） was longer than that of horizontal semicircular canal-BPPV （ （0. 96 ± 1.06） s, t = 5. 546 ,P 〈 0.01 ）. But there were no differences in the gender, the course of disease and the duration of vertigo attack. The patients with posterior semicircular canal-cupulolithiasis were younger than those with posterior semicircular canal-canalithiasis. The duration of vertigo attack of posterior semicircular canal- cupulolithiasis was longer than that of posterior semicircular canal-canalithiasis. The latency and the duration of vertigo attack of horizontal semicircular canal-cupulolithiasis were longer than that of horizontal semicircular canal-canalithiasis and the age was older. Conclusions The posterior semicircular canal is more involved in BPPV. The latency of vertigo attack of posterior semicircular canal-BPPV is longer than that of horizontal semicircular canal-BPPV. The latency and the duration of vertigo attack of horizontal semicircular canal-cupulolithiasis are longer than that of horizontal semicircular canal-canalithiasis and the age is older.
