This study showed that a population with benign paroxysmal positional vertigo related to mild head trauma (BPPVAT) was younger and more frequently presented with bilateral canalithiasis than another population with idiopathic etiology (IBPPV). In both groups, females presented a higher risk of BPPV.
To compare the clinical features of a population with BPPVAT and another with IBBPV.
We carried out statistical analysis of a population of 51 subjects with BPPVAT and another of 325 subjects with IBPPV, comparing age, gender, recurrence of symptoms, associated chronic dizziness (CD), and clinical presentation. Kolmogorov Smirnov test, Student's t test, Mann-Whitney test, 95% binomial confidence interval for proportions, chi-squared, and Fisher's test were used as statistical tools. A significance level of p < 0.05 was considered in all cases.
The population affected with BPPVAT was younger and bilateral canalithiasis was also more frequent. No differences were found in gender distribution, semicircular canals involved in the symptoms, recurrence after repositioning maneuvers, or associated CD.
本研究表明，与轻度头部外伤相关的良性阵发性位置性眩晕患者群体（BPPVAT）比特发性病因的另一群体（IBPPV）更年轻，双侧耳石症更为常见。在两组中，女性患BPPV的风险更高。
比较BPPVAT群体和IBBPV群体的临床特征。
我们对51例BPPVAT患者群体和325例IBPPV患者群体进行了统计分析，比较了年龄、性别、症状复发、相关慢性头晕（CD）和临床表现。使用柯尔莫哥洛夫-斯米尔诺夫检验、学生t检验、曼-惠特尼检验、比例的95%二项式置信区间、卡方检验和费舍尔检验作为统计工具。所有情况下均将显著性水平设为p < 0.05。
BPPVAT患者群体更年轻，双侧耳石症也更常见。在性别分布、症状涉及的半规管、复位操作后的复发或相关CD方面未发现差异。
