Repeated vs single physical maneuver in benign paroxysmal positional vertigo

OBJECTIVES: To evaluate the effectiveness and possible side effects of a single session of repeated particle repositioning maneuver (PRM) to treat posterior canal benign paroxysmal positional vertigo (BPPV) and the usefulness of post-treatment restrictions. MATERIALS AND METHODS: A total of 125 consecutive patients with idiopathic BPPV participated in the study. Fifty patients received a single session of repeated PRM only (group I). Results were compared with those of 50 patients with BPPV who received a single PRM (group IIb), and 25 patients who received a single PRM followed by the use of a neck collar and keeping the head upright for 48 h (group IIa). RESULTS: Forty-six patients (92%) of group I, 40 patients (80%) of group IIb, and 21 patients (84%) of group IIa were completely free of signs and symptoms when re-examined 1 week after treatment. Transient nausea and disequilibrium following treatment were reported equally in all subgroups and well tolerated. Nearly all patients of group IIa considered the post-treatment restrictions very inconvenient. CONCLUSIONS: A single session of repeated physical procedure seems to be clinically superior to one single maneuver and well tolerated. Additional post-treatment measurements are inconvenient and should be abandoned.     

Canal conversion after repositioning procedures: comparison of Semont and Epley maneuver

Although the efficacy of Semont (SM) and Epley maneuvers (EM) for treatment of posterior canal benign paroxysmal positional vertigo (BPPV) is well established, data comparing SM and EM regarding maneuver-induced canal switch are lacking. We prospectively investigated 102 posterior canal BPPV patients after application of the Semont or the Epley maneuver and looked for the appearance of ipsilateral horizontal canal BPPV symptoms. Although treatment success was similar for SM and EM (67 and 76 %, respectively), there was a significant difference in posterior-to-horizontal canal switch rates. In particular, 4 of 51 patients (7.8 %) of the EM group converted to the geotropic type of horizontal canal BPPV, whereas none of the 51 SM patients exhibited a canal switch. All four patients were cleared with a single barbecue maneuver. Our data suggest a small but significant difference in canal switch rate between EM and SM, which could be partly explained by the higher number of maneuver steps during which the head is in the dependent position throughout the EM.

Benign Paroxysmal Positional Vertigo

Benign paroxysmal positional vertigo (BPPV) is characterized by brief recurrent episodes of vertigo triggered by changes in head position. BPPV is the most common etiology of recurrent vertigo and is caused by abnormal stimulation of the cupula by free-floating otoliths (canalolithiasis) or otoliths that have adhered to the cupula (cupulolithiasis) within any of the three semicircular canals. Typical symptoms and signs of BPPV are evoked when the head is positioned so that the plane of the affected semicircular canal is spatially vertical and thus aligned with gravity. Paroxysm of vertigo and nystagmus develops after a brief latency during the Dix-Hallpike maneuver in posterior-canal BPPV, and during the supine roll test in horizontal-canal BPPV. Positioning the head in the opposite direction usually reverses the direction of the nystagmus. The duration, frequency, and symptom intensity of BPPV vary depending on the involved canals and the location of otolithic debris. Spontaneous recovery may be expected even with conservative treatments. However, canalithrepositioning maneuvers usually provide an immediate resolution of symptoms by clearing the canaliths from the semicircular canal into the vestibule.

Clinical implication of cervical vestibular evoked myogenic potentials in benign paroxysmal positional vertigo

Objectives

To evaluate the value of cervical vestibular evoked myogenic potential (cVEMP) as a prognostic factor for benign paroxysmal positional vertigo (BPPV).

Benign paroxysmal positional vertigo

Benign paroxysmal positional vertigo (BPPV) is the most common and most treatable cause of vertigo. In most cases, a simple maneuver that takes less than a few minutes to do resolves the problem. BPPV is caused by misplaced calcium carbonate crystals (otoconia) in the semicircular canal of the inner ear that have broken free from the utricle. When these crystals break free, they either remain loose in one of three different semicircular canals or attach to the hair cells within a canal. Several different types of treatment maneuvers have been described. The maneuver to use varies according to the semicircular canal involved and whether the crystals are loose or attached to the hair cells.     

Benign paroxysmal positional vertigo predominantly affects the right labyrinth

Benign paroxysmal positional vertigo (BPPV) occurs when there are freely moving particles in a semicircular canal and the head is turned in the plane of the affected canal. The aim of the present study was to clarify whether BPPV manifests equally in both labyrinths or whether there is a preponderance for one side. We conducted a PubMed literature search of BPPV case series which specified the affected side and a retrospective chart review of 80 consecutive patients with BPPV of the posterior canal who had presented at our dizziness clinic.Eighteen studies with a total of 3426 patients were identified. In our own series the right side was affected in 54 of 80 patients (right/left ratio 2.08). Altogether, in 3506 patients the right labyrinth was involved 1.41 times more often than the left (95% CI 1.37 to 1.45). We think that the reason for the predominant involvement of the right ear in BPPV is the habit-of most patients-of sleeping on the right side.
