摘要
目的探讨良性阵发性变位性眩晕(BPPV)的临床特点和病因。方法收集521例BPPV患者临床资料,研究其占门诊眩晕和头晕患者的比例、患者的临床特点以及合并偏头痛的情况。结果521例患者占门诊眩晕患者的35.7%,占门诊头晕患者的12.1%。其中男性158例(30.3%),女性363例(69.7%),年龄20～93岁,平均(57.5±12.8)岁。右侧半规管受累323例(62.0%),左侧半规管受累187例(35.9%),双侧半规管受累11例(2.1%)。垂直半规管眼震潜伏期(3.22±2.37)s,持续时间(8.31±7.98)s;水平半规管眼震潜伏期(2.33±1.50)s,持续时间(14.77±11.40)s;垂直与水平半规管BPPV的眼震潜伏期和持续时间比较,差异均有统计学意义(P=0.001,P=0.000)。15例(2.9%)患者在发病前有头部外伤史,39例(7.5%)患者伴有偏头痛病史。结论BPPV在人群中有较高的发病率,应避免漏诊或误诊。
Objective To analyze the clinical features and causes of benign paroxysmal positional vertigo （BPPV）. Methods The clinical data of 521 patients with BPPV were collected. The percentage of patients with BPPV in all the outpatients with dizziness and vertigo, the clinical characteristics of BPPV, and the prevalence of comorbidity with migraine were analyzed. Results BPPV accounted for 35.7% of patients with vertigo and 12. 1% of patients with dizziness. Among the 521 patients with BPPV, 158 （30.3%） were male and 363 （69.7%） were female, with an average age of （57.5 ± 12.8） years old （20 to 93 years old）. Right semicircular canals were involved in 323 cases （62.0%） , and left semicircular canals in 187 cases （35.9%）. The latency period of nystagmus of vertical canals was （3.22±2.37） s, and time of persistence was （8.31 ±7.98） s. The latency period of nystagmus of horizontal canals was （2.33±1.50） s, and the time of persistence was （14.77 ± 11.40） s. There were significant differences in the latency period of nystagmus and time of persistence between the vertical and horizontal canals （P =0. 001 and P =0. 000）. Fifteen patients （2.9%） had a history of head trauma and 39 （7.5%） were complicated with migraine. Conclusion BPPV is prevalent in patients with dizziness and vertigo, and misdiagnosis and missed diagnosis should be avoided.
