Benign paroxysmal positional vertigo (BPPV) is the most common vestibular disorder. However, BPPV in children has been studied less extensively than in the adult population. This is because the observation of benign paroxysmal positional nystagmus (BPPN) in children is technically very difficult and BPPV is rare in children. In this study, we present the only two cases of BPPV in children in which we successfully recorded and analyzed the BPPN.
One case was an 11-year-old boy and the other was a 3-year-old girl. We analyzed their BPPN three-dimensionally.
Apogeotropic positional nystagmus was observed in the first case. We analyzed it to verify the presence of cupulolithiasis in the horizontal semicircular canal (HSCC). Geotropic positional nystagmus was observed in the second case, and the analyzed data indicated the presence of canalolithiasis in HSCC. Over the last decade, we have examined 3341 patients complaining of vertigo or dizziness. Among them, there were 63 children with the same complaint, so that the proportion of cases of BPPV in children was only 3% (2/63).
Among patients complaining of vertigo or dizziness, children with BPPV are rare (3%). However, we have recorded their BPPN to confirm that BPPV does occur in children and that their characteristics of positional nystagmus are generally identical to those in adults. We emphasize that this is the first report of a child as young as 3 years old being diagnosed with BPPV.
良性阵发性位置性眩晕（BPPV）是最常见的前庭疾病。然而，与成人相比，儿童BPPV的研究较少。这是因为在儿童中观察良性阵发性位置性眼震（BPPN）在技术上非常困难，且BPPV在儿童中较为罕见。在本研究中，我们报告了仅有的两例儿童BPPV病例，我们成功记录并分析了其BPPN。
一例为11岁男孩，另一例为3岁女孩。我们对他们的BPPN进行了三维分析。
第一例观察到背地性位置性眼震。我们对其进行分析以证实水平半规管（HSCC）存在壶腹嵴顶耳石症。第二例观察到向地性位置性眼震，分析数据表明HSCC存在管结石症。在过去十年中，我们检查了3341例主诉眩晕或头晕的患者。其中，有63例儿童有相同主诉，因此儿童BPPV病例的比例仅为3%（2/63）。
在主诉眩晕或头晕的患者中，儿童BPPV很少见（3%）。然而，我们记录了他们的BPPN，以证实BPPV确实发生在儿童中，并且他们的位置性眼震特征通常与成人相同。我们强调，这是首例3岁幼儿被诊断为BPPV的报告。
