Prevalence of Horizontal Canal Variant in 3,975 Patients With Benign Paroxysmal Positional Vertigo: A Cross-sectional Study.

ABSTRACT:

Background and objectives

Current understanding based on older studies is that pc-BPPV is far more common than hc-BPPV. Such studies are limited by small sample sizes, and often the supine roll test for hc-BPPV is not performed. To better estimate the prevalence of hc-BPPV, we studied a large cross-section of patients with VOG-diagnosed BPPV.

Of 3,975 patients with VOG-confirmed and specialist-diagnosed BPPV (median a
