## Abstract Involvement of the superior semicircular canal (SSC) in benign paroxysmal positional vertigo (BPPV) is rare. SSC BPPV is distinguished from the more common posterior semicircular canal (PSC) variant by the pattern of nystagmus triggered by the DixβHallpike position: downβbeating torsion

## Abstract Vertical nystagmus occurs in patients with central vestibular system pathology. Lesions of the pons, medulla, and cerebellum lead to vertical nystagmus. Given this association, vertical nystagmus is considered pathognomonic in nature. We present a case of benign paroxysmal positional ve
Objectives/Hypothesis: Horizontal semicircular canal (HSC) benign paroxysmal positional vertigo (BPPV) has been reported to have a poorer prognosis than posterior semicircular canal BPPV. Incorrect determination of the affected ear appears to be one of the causes of poorer outcome. The aim of this s
