OBJECTIVES/HYPOTHESIS: Benign paroxysmal positional vertigo (BPPV) is the most common vestibular disorder with an incidence between 10.7 and 17.3 per 100,000 persons per year. The mechanism for BPPV has been postulated to involve displaced otoconia resulting in canalithiasis. Although particulate matter has been observed in the endolymph of affected patients undergoing posterior canal occlusion surgery, an otoconial origin for the disease is still questioned. STUDY DESIGN: In this study, particulate matter was extracted from the posterior semicircular canal of two patients and examined with scanning electron microscopy...

CONCLUSION: A 30 s observation of geotropic positional nystagmus is sufficient to distinguish persistent geotropic positional nystagmus (PGPN) from transient geotropic positional nystagmus (TGPN) in patients with horizontal canal type of benign paroxysmal positional vertigo (H-BPPV) in ENT office. OBJECTIVE: As a canalith repositioning procedure effectively treats H-BPPV with TGPN, but not PGPN, the differentiation between patients with PGPN and with TGPN is essential...

OBJECTIVE: There are no epidemiological studies quantifying the prevalence of second causes of dizziness in Ménière's disease (MD). Therefore, we aimed to quantify which dizziness-inducing causes are prevalent alongside MD. Moreover, we analyzed which second cause of dizziness was more common in a specific age group and if age was a risk factor. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary referral center. METHODS: Data were retrospectively obtained from all MD patients who visited our clinic between January 2000 and December 2013...

This chapter gives an overview of the epidemiology of dizziness, vertigo, and imbalance, and of specific vestibular disorders. In the last decade, population-based epidemiologic studies have complemented previous publications from specialized settings and provided evidence for the high burden of dizziness and vertigo in the community. Dizziness (including vertigo) affects about 15% to over 20% of adults yearly in large population-based studies. Vestibular vertigo accounts for about a quarter of dizziness complaints and has a 12-month prevalence of 5% and an annual incidence of 1...

The objective of the present study is to analyze the quantitative vestibulo-ocular responses in a group of patients with benign paroxysmal positional vertigo (BPPV) canalolithiasis and compare these data with the data of the tridimensional biomechanical model. This study was conducted on 70 patients that presented idiopathic posterior semicircular canal canalolithiasis. The diagnosis was obtained by Dix-Hallpike maneuvers recorded by videonystagmograph. The present study demonstrates that there is a significant correlation between the intensity of the nystagmus and its latency in cases of BPPV-idiopathic posterior semicircular canal canalolithiasis type...

CONCLUSION: Benign paroxysmal positional vertigo (BPPV) is strongly related to sleep. This study proposes a micro-otoconia accumulation theory in which the pathological debris is an aggregate of micro-otoconia over a long time period, and which begins to slide by its own weight during sleep. OBJECTIVES: To examine the onset time of idiopathic BPPV and to investigate its etiology. METHOD: Patients (n = 351) were classified as posterior canalolithiasis (PC), horizontal canalolithiasis (HC), and horizontal heavy cupula (HHC) according to nystagmus findings...

CONCLUSION: The results showed a gradual detachment of otoconia in the utricle after a single event of head vibration, possibly explaining the frequent recurrence of BPPV attacks and persistent dizziness after trauma. OBJECTIVES: This study developed a murine model of traumatic BPPV and observed the changes in otoconia detachment over time. METHODS: Six-week-old CBA mice were used in this study. Otoconia detachment was induced by vibrating the head for 2 min...

INTRODUCTION: Benign paroxysmal positional vertigo (BPPV) secondary to canalolithiasis of the posterior semicircular canal is perhaps the most frequent cause of vertigo and dizziness. One of its properties is a high response rate to canalith repositioning maneuvers. However, delays in the diagnosis and treatment of this entity can range from days to years, depending on the setting. Here, we present an abbreviated variation of the Dix-Hallpike maneuver, which can be used to diagnose this disease...

OBJECTIVE: Several previous studies have demonstrated that comorbidities, secondary causes, physical inactivity, and osteoporosis may cause recurrence of benign paroxysmal positional vertigo (BPPV). However, there has also been some controversy over the clinical course(s) and cause(s) of recurrent BPPV (rBPPV). We identified clinical features and associated factors, including decreased bone mineral density, in the recurrence of BPPV. METHODS: In total, 198 patients with idiopathic BPPV, diagnosed at the otolaryngology clinics of Seoul National University Boramae Medical Center, were enrolled...

Benign paroxysmal positional vertigo (BPPV) is an unfamiliar and rare complication occurring following osteotome sinus floor elevation (OSFE) and simultaneous implant placement. Etiology of this disorder is commonly displacement of otoliths by vibratory forces transmitted by osteotomes and mallet along with the hyperextension of the head during the operation, causing them to float around in the endolymph. This report presents a case of protracted BPPV following OSFE and simultaneous implant placement. A 43-year-old female suffered intense vertigo and nausea immediately after implant placement using an OSFE procedure...
