Background/aim: Benign paroxysmal positional vertigo is one of the most frequent peripheral vestibular system disorders. The aim of this study was to examine the efficacy of the Epley maneuver in treating benign paroxysmal positional vertigo of the posterior semicircular canal (p-BPPV) and to discover possible causes of failure.

Methods: This prospective study included 75 patients.

Extracts from the Cochrane Library: modifications of the Epley (canalith repositioning) maneuver for posterior canal benign paroxysmal positional vertigo.

The "Cochrane Corner" is a quarterly section in the Journal that highlights systematic reviews relevant to otolaryngology-head and neck surgery, with invited commentary to aid clinical decision making. This installment features a Cochrane review "Modifications of the Epley (Canalith Repositioning) Manoeuvre for Posterior Canal Benign Paroxysmal Positional Vertigo (BPPV)" that finds no evidence of benefit for mastoid oscillation applied during the Epley maneuver nor any clinically important benefit for post-Epley postural restrictions in comparison with the Epley maneuver alone.

Clinical features of recurrent or persistent benign paroxysmal positional vertigo.

Objectives: To identify clinical features and causes of recurrent or persistent benign paroxysmal positional vertigo (BPPV) and to analyze the effectiveness of frequently repeated canalith repositioning procedures (CRPs).

Setting: Academic university hospital.

Canal switch after canalith repositioning procedure for benign paroxysmal positional vertigo.

Canal switch is a complication following canalith repositioning procedure (CRP) for posterior canal benign paroxysmal positional vertigo (BPPV). Instead of being returned to the utricle, the loose otoconia migrate into the superior or horizontal semicircular canal. Patients remain symptomatic, and treatment can be ineffective unless the switch is recognized and additional repositioning maneuvers directed toward the appropriate semicircular canal are performed.

The Role of Postural Restrictions after BPPV Treatment: Real Effect on Successful Treatment and BPPV's Recurrence Rates.

Background. Canalith repositioning techniques are adequately established in the literature, as the treatment of choice for benign paroxysmal positional vertigo. However, the role of the posttreatment instructions is still not clearly defined.

Modifications of the Epley (canalith repositioning) manoeuvre for posterior canal benign paroxysmal positional vertigo (BPPV).

Background: Benign paroxsymal positional vertigo (BPPV) is a syndrome characterised by short-lived episodes of vertigo associated with rapid changes in head position. It is a common cause of vertigo presenting to primary care and specialist otolaryngology (ENT) clinics. BPPV of the posterior canal is a specific type of BPPV for which the Epley (canalith repositioning) manoeuvre is a verified treatment.

Treatment of the horizontal semicircular canal canalithiasis: pros and cons of the repositioning maneuvers in a clinical study and critical review of the literature.

Objective: Several repositioning maneuvers have been proposed for the treatment of benign paroxysmal positional vertigo (BPPV) due to canalithiasis of the horizontal semicircular canal (HSC). However, comparisons between these canalith repositioning procedures as well as a generally accepted algorithm for the management of HSC canalithiasis are currently lacking. The aim of this study was to compare the efficacy of 3 different treatment proposals and review the relevant literature.

Malignant paroxysmal positional vertigo.

Objective: An insidious percentage of paroxysmal positional vertigo appears to be intractable with canalith repositioning maneuver and also is not self-limiting. This type of positional vertigo is sustained by the action of intracranial tumors that mimics the clinical aspects of benign paroxysmal positional vertigo.Aim of this study is to clarify the features of these forms of positional vertigo, which we indicate as malignant paroxysmal positional vertigo.

Are postural restrictions necessary for management of posterior canal benign paroxysmal positional vertigo?

Objectives: An important component of management of benign paroxysmal positional vertigo (BPPV) has been the application of postural restrictions after use of a canalith repositioning maneuver (CRM) to prevent the return of otolithic debris into the posterior semicircular canal (PSC). This study was designed to explore the effectiveness of postural restrictions in patients with BPPV caused by otolithic debris in the PSC.

Methods: Seventy-four adult patients with unilateral PSC BPPV were enrolled into this study.

Diagnosis of Single- or Multiple-Canal Benign Paroxysmal Positional Vertigo according to the Type of Nystagmus.

Benign paroxysmal positional vertigo (BPPV) is a common peripheral vestibular disorder encountered in primary care and specialist otolaryngology and neurology clinics. It is associated with a characteristic paroxysmal positional nystagmus, which can be elicited with specific diagnostic positional maneuvers, such as the Dix-Hallpike test and the supine roll test. Current clinical research focused on diagnosing and treating various types of BPPV, according to the semicircular canal involved and according to the implicated pathogenetic mechanism.

Bilateral multicanal benign paroxysmal positional vertigo coexisting with a vestibular schwannoma: case report.

We describe a rarely encountered case of coexisting bilateral multicanal benign paroxysmal positional vertigo (BPPV) and vestibular schwannoma in a 56-year-old woman. The patient had presented with a 10-year history of dizziness and imbalance, and her vestibular findings were perplexing. We decided on a working diagnosis of BPPV and began treatment.

Acute vestibulopathy.

The presentation of acute vertigo may represent both a common benign disorder or a life threatening but rare one. Familiarity with the common peripheral vestibular disorders will allow the clinician to rapidly "rule-in" a benign disorder and recognize when further testing is required. Key features of vertigo required to make an accurate diagnosis are duration, chronicity, associated symptoms, and triggers.

Objective: To explore the clinical value of dynamic posturography in the evaluation and rehabilitation of vestibular function of patients with benign paroxysmal positional vertigo (BPPV).

Methods: A total of 48 patients with BPPV of posterior semicircular canal in vertigo clinic of our hospital from May 2007 to December 2008 were retrospectively analyzed in this study. All patients underwent the inspection of caloric test, static posturography, and dynamic posturography.

Management of benign paroxysmal positional vertigo with the canalith repositioning maneuver in the emergency department setting.

Vertigo is a common clinical manifestation in the emergency department (ED). It is important for physicians to determine if the peripheral cause of vertigo is benign paroxysmal positional vertigo (BPPV), a disorder accounting for 20% of all vertigo cases. However, the Dix-Hallpike test--the standard for BPPV diagnosis--is not common in the ED setting.
