OBJECTIVE We investigated the neuro-otological findings, including nystagmus, and the clinical course of patients with the horizontal canal variant of benign paroxysmal positional vertigo (HC-BPPV), who showed spontaneous inversion of nystagmus without a positional change. Furthermore, we speculated on the possible mechanism of spontaneous inversion of nystagmus without a positional change. P...

During the treatment process for benign paroxysmal positional vertigo (BPPV) using canalith repositioning procedure, otolith can inadvertently enter semicircular canal instead of utricle. Canal conversion refers to situation where enters a different canal, while reentry occurs when returns same canal. The occurrence complicate accurate diagnosis and BPPV, potentially leading misdiagnosis unsucc...

Benign paroxysmal positional vertigo (BPPV) is the most common cause of and nystagmus. Direction-changing nystagmus (DCPN), which refers to change in direction with different head positions, a well-known characteristic horizontal semicircular canal BPPV. The supine roll test commonly used diagnose However, persistent geotropic DCPN observed during this cannot be explained by conventional mechan...

BACKGROUND The Dix-Hallpike manoeuvre is performed for diagnosis and the Epley manoeuvre used for treatment of posterior canal benign paroxysmal positional vertigo (BPPV). However, musculoskeletal conditions may restrict utility of these manoeuvres. OBJECTIVE The Semont and liberatory manoeuvres are described in this article. These manoeuvres are simple and highly effective for the diagnosis ...

Down-beating positional nystagmus is typically associated with central nervous system disease. Anterior canal benign paroxysmal positional vertigo (AC-BPPV) can mimic down-beating positional nystagmus of central origin, particularly when it is bilateral. Factors that increase the probability of bilateral AC-BPPV include a history of bilateral multicanal BPPV, transient down-beating and torsiona...

UNLABELLED Benign Paroxysmal Positional Vertigo (BPPV) can cause falls, especially in the elderly. AIM to study whether or not elderly patients with BPPV have a reduction on their falls after the particle repositioning maneuver (PRM). MATERIALS AND METHODS retrospective study including elderly with BPPV who had fall(s) during the last year. All patients were submitted to the PRM according t...

PURPOSE The aim of this study was to describe the clinical features and video-oculographic findings in patients with anterior semicircular canal benign paroxysmal positional vertigo (BPPV). MATERIALS AND METHODS STUDY DESIGN This is a prospective case series. SETTING The study was set at an outpatient clinic in a general hospital. PATIENTS Fourteen individuals with symptoms of BPPV and...

Benign paroxysmal positional vertigo of the horizontal semicircular canal (HC-BPPV) is a well-defined syndrome characterized by direction-changing horizontal positional nystagmus. We report the clinical features of 5 patients who illustrate the possible variables of the syndrome. In most cases, nystagmus is geotropic and more intense when the pathological ear is lowermost; less often the syndro...

Objectives Brandt-Daroff exercises (BDEs) are commonly used as an at-home treatment for posterior canalithiasis, but their efficacy in the of benign paroxysmal positional vertigo (BPPV) horizontal canal (HC-BPPV) has not been previously studied. Using biomechanical model simulation, we investigated modifications that may optimize BDE use HC-BPPV treatment. Materials and methods The BPPV Viewer,...

UNLABELLED Benign paroxysmal positional vertigo (BPPV) of lateral semicircular canal (LSC) is one of the rarer forms of BPPV as compared to posterior semicircular canal BPPV. Various particle repositioning manoeuvres have been described in the literature as a mode of treating this condition. PURPOSE Evaluation and discussion of the procedure of the Gufoni's manoeuvre and its advantages in the...
