The objective of the present review of the literature is the analysis of the currently available data concerning etiology and pathogenesis of benign paroxysmal positional vertigo (BPPV). The special emphasis is placed on the modern hypotheses of BPPV formation that collectively account for not more than 15% of all known cases of this condition. The best explored are the following causes of benign paroxysmal positional vertigo: vestibular neuronitis, head injuries, and disorders in the middle ear. During the recent years, much attention has been given to the role of disturbances of calcium metabolism and osteoporosis in etiology of benign paroxysmal positional vertigo...

BACKGROUND: Although benign paroxysmal positional vertigo and endolymphatic hydrops are considered to be distinct diagnoses, a minority of vertiginous patients exhibit features of both conditions. This coincidence has been reported previously in the literature, and is reviewed here in terms of possible aetiology. RESULTS AND CONCLUSION: A new hypothesis to account for both conditions is offered, implicating free-floating degenerating debris from the otolithic apparatus...

BACKGROUND AND PURPOSE: Deciphering the cause for a persistent, direction-changing geotropic nystagmus can be difficult. Migraine and light cupula are two possible causes, though can be confused with benign paroxysmal positional vertigo (BPPV) affecting the horizontal semicircular canal. In migraine, the persistent geotropic nystagmus tends to be slow; in light cupula, the nystagmus has been illustrated to beat in the direction opposite that of prone positioning. CASE DESCRIPTION: Here we describe a patient with initial occurrence then recurrence of a high velocity (≥30 deg/sec), persistent direction-changing geotropic nystagmus and vertigo with an intensity variable based on head position, which was difficult to manage...

Benign paroxysmal positional vertigo (BPPV) remains the most frequent cause of vertigo. The TRV chair is a mechanical device suited for optimization of managing complex cases of BPPV. Although the use of repositioning devices in the management of BPPV is increasing, no applicable guide for the TRV management of the different BPPV subtypes exists. This article presents the techniques for addressing canalolithiasis and cupulolithiasis in the TRV chair for each affected semicircular canal. In a tertiary referral centre like our unit the TRV chair is an asset in the management of BPPV...

The benign paroxysmal positional vertigo (BPPV) is a vestibular disorder cause of vertigo. The BPPV may be corrected mechanically by repositioning maneuvers but even after successful maneuvers, some patients report residual dizziness for a certain period afterward. Early recognition and treatment might decrease the incidence of residual dizziness in patients with BPPV, especially in those patients with psychiatric comorbidities and in the elderly, lowering the risk of falling. Many pathogenetic hypotheses for residual dizziness are under debate...

INTRODUCTION: Benign paroxysmal positional vertigo (BPPV) is managed with particle repositioning maneuvers (PRM), following which patients are advised of activity restrictions to prevent recurrence. This can include wearing a cervical collar. OBJECTIVE: Does the use of BPPV postprocedure restriction with a cervical collar impact on the number of PRMs required to resolve a patient's symptoms? METHOD: Combination of retrospective and prospective review of 624 patients treated in a tertiary UK hospital...

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...

INTRODUCTION AND OBJECTIVES: The set of symptoms relating to disorders of the balance system are common in the general population. However, there are few studies quantifying the frequency of onset of the various vestibular disorders that present in specialist otoneurology units in the Spanish population. The aim of this study is to establish the epidemiology of vestibular disorders, their form of presentation, and the expected care burden in a specialist otoneurology clinic. MATERIAL AND METHODS: A retrospective, descriptive, observational study of patients referred to the otoneurology unit of a third level hospital between 1/1/2015 and 31/12/2015...

The aim of this review was to analyze the existing literature concerning the relationship between Hashimoto's thyroiditis (HT) and vestibular dysfunction. METHODS: We used electronic databases (PubMed, EMBASE, Cochrane Library) to search and collect all published articles about association between HT and vestibular disorders. RESULTS: Several observational and retrospective studies have postulated a relationship of thyroid autoimmunity and vestibular disorders. In most cases, an appropriate control group was lacking and the impact of thyroid functional status could not precisely be established...

Vertigo and dizziness are among the most common chief complaints in the emergency department. Etiologies can be categorized into three subgroups: neurootological (vestibular), medical (especially cardiovascular, metabolic), and psychiatric disorders. The diagnostic approach in the emergency department is based on a systematic analysis of case history (type, time course of symptoms, modulating factors, associated symptoms), clinical examination of the vestibular, ocular motor, and cerebellar systems (head impulse test, nystagmus, skew deviation, positioning maneuver, test of gait and stance), as well as a basal monitoring (vital signs, 12-lead ECG, blood tests)...

BACKGROUND: Horizontal semicircular canal BPPV (HSC-BPPV) can occur in 10-30% of BPPV cases. Lower success rates are reported for HSC-BPPV. The apogeotropic form of HSC-BPPV is more difficult to treat, as 5-40% of cases are described to be refractory to repositioning maneuvers. PURPOSE: To describe the assessment and treatment of a patient presenting with HSC-BPPV and to demonstrate the potential use of Forced-Prolonged Positioning (FPP) as a home exercise program (HEP) for persistent HSC-BPPV in an elderly patient...

OBJECTIVES/HYPOTHESIS: Although it is generally considered that benign paroxysmal positional vertigo (BPPV) is associated with changes in female sex hormone levels, no direct data have been reported until now. The purpose of this article was to provide direct data showing the distinct relationship between female sex hormone fluctuations and BPPV in postmenopausal female patients. STUDY DESIGN: Prospective analysis in humans and basic research in animals. METHODS: Blood samples were analyzed to determine the levels of estradiol, progesterone, follicle-stimulating hormone, and luteinizing hormone in 50- to 80-year-old postmenopausal female patients newly diagnosed with idiopathic BPPV based on history compatible with BPPV and positive provocative maneuvers...

Balance is achieved and maintained by a balance system called a labyrinth that is composed of three semicircular canals and the otolith organs that sense linear gravity and acceleration. Within each semicircular canal, there is a gelatinous structure called the cupula, which is deformed under the influence of the surrounding endolymph. One of the balance disorders is benign paroxysmal positional vertigo, and one of the pathological conditions that have been identified as possible causes of this syndrome is canalithiasis-disturbance of the endolymph flow and cupular displacement caused by the free-moving otoconia particles within the lumen of the canal...
