OBJECTIVES: To evaluate the value of cervical vestibular evoked myogenic potential (cVEMP) as a prognostic factor for benign paroxysmal positional vertigo (BPPV). METHODS: We reviewed 65 patients with BPPV who underwent cVEMP. Patients were divided into two groups according to resistance to the repositioning maneuver. Univariable and multivariable analyses were performed with age, gender, affected semicircular canal, affected side and cVEMP parameters to find the associated factors for resistance to the repositioning maneuver...

A 60-year-old man presented with a 10-month history of of stereotypical spells characterized by vertigo, tinnitus, blurred vision, left hemibody numbness, and occasional syncope, precipitated by turning his head leftwards. Cerebral angiography and CT angiography of the head and neck with provocative maneuvers did not demonstrate vertebral artery narrowing. However, there was narrowing of the left internal jugular vein due to extrinsic compression from the sternocleidomastoid with leftward head rotation in the setting of hypoplasia of the right internal jugular vein...

OBJECTIVE: Although there has been a wide consensus on the mechanism of nystagmus and clinical presentation of benign paroxysmal positional vertigo (BPPV), the neuroepithelial pathophysiology of BPPV still remains unclear. In this study, we aimed to clarify the pathophysiology of BPPV by evaluating the cervical vestibular-evoked myogenic potential (cVEMP) findings of patients. MATERIALS AND METHODS: Thirty-six BPPV patients and 20 healthy volunteers were included...

OBJECTIVE: Endolymphatic sac decompression (ESD) for the treatment of Ménière's disease (MD) has had limited success and variable results in the literature. We have devised a novel technique that involves blocking the endolymphatic duct with surgical clips. In a separate effort to study the endolymphatic sac (ELS), we have sectioned the lateral part of the main body of the ELS as biopsies from a subset of patients. We aimed to evaluate the effect of the lateral part sectioning of the ELS on short-term surgical outcomes...

OBJECTIVE: To investigate the effectiveness of unilateral posterior semicircular canal (PSCC)-plugging surgery for patients with intractable bilateral PSCC-type benign paroxysmal positional vertigo (P-BPPV). METHODS: From July 2011 to December 2015, we diagnosed 136 patients with P-BPPV. Of these, 3 patients had bilateral P-BPPV, and in 2 of the 3, the condition had been refractory to conservative treatment for more than 1 year. We planned a staged PSCC-plugging surgery for these 2 patients; initially one side was treated, and the contralateral side was treated 6 months later...

The apogeotropic variant of horizontal semicircular canal benign paroxysmal positional vertigo (HC-BPPV) is attributed to canalithiasis of the anterior arm or cupulolithiasis. Despite some therapeutic maneuvers, I propose a new treatment strategy for apogeotropic HC-BPPV that is designed to detach both the otoconial debris from the anterior arm of the semicircular canal and the debris that is attached to the utricular side of the cupula using inertia and gravity and based on simulations with a 3D biomechanical model...

OBJECTIVE: Vestibular dysfunction is a well-recognized complication of type 2 diabetes (DM) that may contribute to increased fall risk. The prevalence of benign paroxysmal positional vertigo (BPPV) is higher in people with DM. The impact of DM on the otolith organs of the vestibular system in people with BPPV is unknown. The purpose of this study was to analyze otolith function using vestibular-evoked myogenic potential (VEMP) tests in people with DM and concurrent BPPV (BPPV + DM), and to examine the relationships between VEMP variables and diabetes-related variables...

CONCLUSION: The Li maneuver is a safe, effective, and simple repositioning method for the treatment of BPPV. It is simple to master and exerts an exact effect. As a rapid repositioning method, the Li maneuver can result in reduced treatment times and increased treatment efficacy, and is, therefore, especially suitable for patients with limited cervical spine movement. OBJECTIVE: To compare the short-term efficacies of the Li and Epley maneuvers in treating posterior canal benign paroxysmal positional vertigo (PC-BPPV)...

CONCLUSION: Elevated Motion Sickness Susceptibility (MSS) in Meniere?s disease (MD) is likely to be a consequence of the onset of MD and not migraine per se. OBJECTIVES: Pathologies of the vestibular system influence MSS. Bilateral vestibular deficits lower MSS, vestibular neuritis or benign paroxysmal positional vertigo have little overall effect, whereas vestibular migraine elevates MSS. However, less is known about MSS in MD, a condition in which many patients experience vestibular loss and migraine symptoms...

BACKGROUND: Positional compression of the vertebral artery (VA) owing to cervical spondylosis is an uncommon cause of stroke. We report two cases of cervical spondylosis causing wake-up stroke, which is extremely rare. CASE DESCRIPTION: The first patient was a 78-year-old woman with vertigo and vomiting lasting from waking up. Magnetic resonance imaging (MRI) and angiography documented right cerebellar infarction, and stenosis of the right cervical VA. Dynamic angiography revealed that the right VA was occluded when her neck was extended or rotated to the right...

The Le Fort I osteotomy is widely used to correct dentofacial deformities. Benign paroxysmal positional vertigo (BPPV) is a common vestibular end organ disorder characterized by short, often recurrent episodes of vertigo. Head trauma is one of the known causes of BPPV. During pterygoid osteotomy, the surgical trauma induced by percussion with the surgical mallet and osteotomes can displace otoliths into the semicircular canal, resulting in BPPV. The aim of this study was to evaluate the potential risk of occurrence of BPPV in individuals undergoing Le Fort I osteotomy...

Vertigo and dizziness are with an annual incidence of more than 10% and a lifetime prevalence of more than 30% among the most frequent symptoms. The keys to the diagnosis are the patient history and the bedside examination: a) for the patient history the time course, type and triggers of symptoms and accompanying symptoms, b) for the clinical examination of the vestibular system the head-impulse test (HIT), the examination for a spontaneous nystagmus, a displacement of subjective visual vertical, a positional nystagmus and the Romberg test, and c) for the differentiation between an acute peripheral and central vestibular lesion the skew deviation, central fixation nystagmus, gaze-evoked nystagmus, saccadic smooth pursuit and a normal HIT...
