Abstract
ObjectiveThe clinical features and incidence of benign paroxysmal positional vertigo (BPPV) are not well known in pediatric populations. The aim of this study was to describe the clinical characteristics of pediatric BPPV and to estimate the frequency of pediatric BPPV in the general population. MethodsWe retrospectively reviewed the medical records of 20 children (6–14 years old) diagnosed with BPPV between 2007 and 2017. The age/sex distribution of BPPV for all ages at our hospital and in the Korean Health Insurance Review and Assessment Service-National Patient Sample (HIRA-NPS) database were compared. The annual incidence and proportion of children with BPPV were calculated. ResultsBPPV occurred 1.86 times more frequently in girls than in boys. Nine children (45%) had associated comorbidities, such as inner ear disorders and recent head trauma. The posterior and lateral semicircular canals were most commonly involved (n = 9 for each), and recurrence was observed in two patients (10%). Children younger than 15 years accounted for approximately 1% of all BPPV cases. The annual incidence of BPPV was 171.5/100,000 for all ages and 9.5/100,000 in the pediatric population. ConclusionsOur findings suggest that pediatric BPPV is a relatively uncommon cause of vertigo in children and that the rates of related illness and recurrence are high.
