良性阵发性位置性眩晕临床特征分析

Clinical analysis of benign paroxysmal positional vertigo

目的观察良性阵发性位置性眩晕(BPPV)患者的临床特征和疗效。方法回顾性分析1000例符合标准的BPPV患者病例资料并行数据分析。结果 (1)男女发病年龄无显著性差异,发病率有显著性差异;(2)单个半规管受累993例,两个半规管受累7例,管石型818例,嵴帽型175例;(3)后半规管587例,外半规管402例,上半规管4例,右侧发病率明显高于左侧;(4)管石型和嵴帽型平均治疗次数差异有统计学意义;(5)BPPV管石型与嵴帽型复位治疗,1次治愈率分别为62.5%与42.3%;(6)外半规管管石型BPPV患侧、健侧眼震慢相角速度及差值与复位治疗次数无相关性。结论 BPPV具有中老年高发、女性多、单个半规管受累多、后半规管最多、外半规管次之、上半规管最少、右耳易受累、管石型多、嵴帽型平均治疗次数多等特点。

OBJECTIVE To observe the clinical characteristics and curative effect inpatients with benign paroxysmal positional vertigo（BPPV）. METHODS The data of 1000 BPPV patients were retrospectively analyzed.RESULTS 1. There was no sisgnificant difference in age between men and women; There was significant difference in incidence between men and women; 2. The single semicircular canal was involved in 993 cases, 2 semicircular canals were involved in 7 cases, canalolithiasis in 818 cases,cupulolithiasis in 175 cases; 3. The posterior semicircular canalwas involved in 587 cases, horizontal semicircular canal in 402 cases, anterior semicircular canal in four cases.The incidence of the right side was significantly higher than that of the left side; 4. The average treatment times of canalolithiasis and cupulolithiasiswere statistically different;5. BPPV canalolithiasis and cupulolithiasisonetimerepositi on cure rate is 62.5% and 42.3% respectively; 6. There was no correlation between nystagmus velocity,affected sideand reposition times in horizontal BPPV. CONCLUSION BPPV has the following characteristicscs. First of all,popularin the middle-aged, elderly population and more common in women, single semicircular canal involve predominantly. Second, most of BPPV involve posterior semicircular canal, horizontal semicircular canal lesion take the second place and anterior semicircular canal lesion was least. Most of BPPV occur in the right side andiscanalolithias type. Thirdly, the average treatment times of BPPV of cupulolithiasis type is more than that of canalolithiasistype.
