ABSTRACT

INTRODUCTION: Horizontal canal benign paroxysmal positional vertigo (HCBPPV) is one form of benign paroxysmal positional vertigo. HC-BPPV is characterized by intermittent recurrent episodes of vertigo following a change in head position relative to gravity. HC-BPPV prevalence ranges from 5%-33% of all dizziness cases seen in otolaryngology, neurology and family physician clinics. Various factors, such as ear and head injury, can cause HC-BPPV. Cardiovascular disease and iatrogenic reasons are also implicated. Despite the prevalence of the disease, there are various forms of diagnostic procedures, some of which are unfamiliar to the therapist and some are controversial. This review aims to present the full range of methods of diagnosis of HC-BPPV, presenting their advantages and disadvantages.
