Vestibulo-Ocular Reflex Abnormalities in Posterior Semicircular Canal Benign Paroxysmal Positional Vertigo: A Pilot Study
Introduction: Benign paroxysmal positional vertigo (BPPV), involving the semicircular canals, is one of the most common diseases of the inner ear. The video head impulse test (vHIT) is a new test that examines the function of the canals. This study aimed to investigate the vestibulo-ocular reflex (VOR) gain, gain asymmetry and saccades after stimulating all six canals in patients definitively d...
متن کاملInner-ear function test in cases of posterior canal-type benign paroxysmal positional vertigo.
Otolaryngologists typically perform diagnoses and offer medical treatment for vestibular dysfunction. This vestibular dysfunction manifests as benign paroxysmal positional vertigo (BPPV), Ménière's disease, vestibular neuronitis, and so on. The etiology of BPPV is still not clear, so in this article we discuss inner-ear function, etiology, and factors related to BPPV. We examined by pure-tone a...
متن کاملDynamics of canal response to head-shaking test in benign paroxysmal positional vertigo.
CONCLUSIONS Time constant and maximum slow phase velocity (SPV) of head-shaking nystagmus (HSN) demonstrated a differential canal response to head shaking in 24% of patients with posterior canal benign paroxysmal positional vertigo (BPPV). We suggest that vestibular lithiasis has a limited contribution to the mechanism that generates HSN. OBJECTIVE To determine the canal response to head shak...
متن کاملBenign paroxysmal positional vertigo.
Benign paroxysmal positional vertigo (BPPV) is the most common cause of recurrent vertigo and has a lifetime prevalence of 2.4% in the general population. Benign paroxysmal positional vertigo is caused when calcium carbonate material originating from the macula of the utricle falls into one of the semicircular canals. Due to their density relative to the endolymph, they move in response to grav...
متن کامل[Efficacy of Epley maneuver in treatment of benign paroxysmal positional vertigo of the posterior semicircular canal].
BACKGROUND/AIM Benign paroxysmal positional vertigo is one of the most frequent peripheral vestibular system disorders. The aim of this study was to examine the efficacy of the Epley maneuver in treating benign paroxysmal positional vertigo of the posterior semicircular canal (p-BPPV) and to discover possible causes of failure. METHODS This prospective study included 75 patients. In all the c...
