OBJECTIVE To determine the recurrence rate of benign positional paroxysmal vertigo (BPPV) and the factors associated to such recurrences. STUDY DESIGN Prospective study. METHOD Sixty-nine consecutive patients treated for first episode of BPPV. STUDY PERIOD 63 months. Mean follow-up: 47 months. RESULTS The recurrence rate was 27%. Fifty percent of recurrences occurred in the first 6 mont...

OBJECTIVES To determine the characteristics and diagnostic value of pseudo-spontaneous and head-shaking nystagmus (HSN) in benign paroxysmal positional vertigo involving the horizontal semicircular canal (HC-BPPV). STUDY DESIGN Retrospective case series review. METHODS After excluding 19 patients with canal paresis, abnormal head impulse test, recent history of peripheral or central vestibu...

The morbidity of benign paroxysmal positional vertigo (BPPV) was investigated from the functional standpoint by analyzing nystagmus elicited by the caloric test. As a result of an investigation of the three (horizontal, vertical and torsional) components of the nystagmus elicited by the caloric stimulus (cold water), the vertical nystagmus differed in direction between the left and the right ea...

BACKGROUND Presently, the unambiguous diagnosis of benign paroxysmal positioning vertigo (BPPV) requires the detection of positioning or positional nystagmus provoked by Dix-Hallpike (for vertical semicircular canals) or supine roll (for horizontal semicircular canals) manoeuvres, which indicates canalo- or cupolithiasis of affected semicircular canals. There are patients, however, in whom--des...

BACKGROUND Lateralization of horizontal semicircular canal benign paroxysmal positional vertigo (HSC-BPPV) is very important for successful repositioning. The directions of lying-down nystagmus (LDN) and head-bending nystagmus (HBN) have been used as ancillary findings to identify the affected sites. This retrospective study was performed to evaluate the lateralizing values of LDN and HBN using...

OBJECTIVE To investigate the vestibular evoked myogenic potentials (VEMPs) resulting in benign paroxysmal positional vertigo (BPPV) patients and to verify its clinical applications in BPPV. STUDY DESIGN A prospective study. SETTING Tertiary referral dizziness center. PATIENTS Forty-one patients with diagnosis of BPPV and 92 healthy volunteers who underwent VEMP testing. INTERVENTION Pat...

OBJECTIVE BPPV localized in the horizontal semicircular canal is an infrequent entity. Nowadays there are controversies about the different treatments available. The objective of this study is to present our results. MATERIAL AND METHODS A multicenter and retrospective study was performed in 31 patients diagnosed of BPPV-HSC between January 1996 and May 2004. RESULTS cupulolithiasis was dia...

Involvement of the superior semicircular canal (SSC) in benign paroxysmal positional vertigo (BPPV) is rare. SSC BPPV is distinguished from the more common posterior semicircular canal (PSC) variant by the pattern of nystagmus triggered by the Dix-Hallpike position: down-beating torsional nystagmus in SSC BPPV versus up-beating torsional nystagmus in PSC BPPV. SSC BPPV may be readily treated at...

Background: Benign paroxysmal positional vertigo (BPPV) is a common vestibular disorder. BPPV may be due to surgery, but it is a rare complication of non-craniofacial surgery. Diagnosis and treatment of BPPV remain challenging in postoperative patients. We present a case of BPPV secondary to spinal surgery and the diagnostic and treatment outcomes. The possible underlying etiologic and pathophy...

Objectives: This study was performed to determine characteristics and the prognostic values in idiopathic sudden sensorineural hearing loss (SSNHL) with comorbid ipsilateral canal paresis (CP) and/or benign paroxysmal positional vertigo (BPPV). Methods: Of 338 patients a diagnosis of SSNHL, 29 (8.6%) CP 24 (7.1%) BPPV were recruited compared 23 SSNHL but without or BPPV. The evaluated for their...
