Paroxysmal Positional Vertigo

A rare case of a 38-year-old female patient who developed benign paroxysmal positional vertigo (BPPV) three weeks after head trauma is presented. The disease manifested bilaterally, which is not uncommon posttraumatically, but in this case, it manifested itself as canalithiasis of the posterior canal on both sides and cupulolithiasis of the right lateral canal, which to our knowledge is a unique and, until now, unpublished case. The aim of this review is to point out the fact that, in such a complex multicanal and bilateral clinical presentation of BPPV, it is not sufficient to perform only positioning but also additional laboratory tests. With a good knowledge of the etiopathogenesis, pathophysiology and clinical forms of BPPV, we can, in most cases, make an accurate and precise diagnosis of the disease and carry out appropriate treatment.

Paroxysmal Positional Vertigo

BACKGROUND: Patients with posterior- and lateral-(canal)-benign paroxysmal positional vertigo (BPPV)-canalolithiasis sleep in the affected-ear-down head position. Posterior-BPPV-canalolithiasis typically affects the right than left ear; sleeping in the right-ear-down head position may be causal. OBJECTIVE: To investigate the relationship between habitual head position during sleep and the onset of BPPV variants. METHODS: Among 1,170 cases of BPPV variants with unknown etiology, the affected ears, habitual head positions during sleep based on interviews, and relationships among them were investigated. RESULTS: Posterior-BPPV-canalolithiasis and lateral-BPPV-canalolithiasis-geotropic affected the right ear significantly more often. Significantly more patients with posterior-BPPV-canalolithiasis and lateral-BPPV-canalolithiasis-apogeotropic habitually slept in the right-ear-down head position. Patients with posterior- and lateral-BPPV-canalolithiasis and light cupula were more likely to sleep habitually in the affected-ear-down position than in the healthy-ear-down head position; no relationship was observed in patients with posterior- and lateral-BPPV-cupulolithiasis. In patients with posterior-BPPV-canalolithiasis and lateral-BPPV-canalolithiasis-geotropic, the proportion of right-affected ears in those sleeping habitually in the right-ear-down head position was significantly greater than that for the left-affected ear. CONCLUSIONS: A habitual affected-ear-down head position during sleep may contribute to BPPV-canalolithiasis and light cupula onset, but not BPPV-cupulolithiasis onset. However, habitual sleeping in the right-ear-down head position cannot explain the predominance of right-affected ears.

Paroxysmal Positional Vertigo

Here, we report a patient with persistent positional upbeat nystagmus in a straight supine position with no evident abnormal central nervous system findings. A 43-year-old woman with rotatory positional vertigo and nausea visited our clinic 7 days after the onset. Initially, we observed persistent upbeat nystagmus in straight supine position with a latency of 2 s during the supine head roll test. However, an upbeat nystagmus disappeared on turning from straight to the left ear-down supine position, and while turning from the left to right ear-down position, an induced slight torsional nystagmus towards the right for >22 s was observed. In the Dix–Hallpike test, the left head-hanging position provoked torsional nystagmus towards the right for 50 s. In prone seated position, downbeat nystagmus with torsional component towards the left was observed for 45 s. Neurological examination and brain computed tomography revealed no abnormal findings. We speculated that persistent positional upbeat nystagmus in this patient was the result of canalolithiasis of benign paroxysmal positional vertigo of bilateral posterior semicircular canals.

Paroxysmal Positional Vertigo

AbstractObjective:The aim of this study was to investigate the frequency of posterior semicircular canal benign paroxysmal positional vertigo in each ear, and to assess the association between the ear affected by benign paroxysmal positional vertigo and the head-lying side during sleep onset. Based on a previous study which used objective methods to prove the preference of the elderly for the right head-lying side during sleep, we hypothesised that a predominance of the same head-lying side in benign paroxysmal positional vertigo patients may affect the pathophysiology of otoconia displacement.Study design:We conducted a prospective study of out-patients with posterior semicircular canal benign paroxysmal positional vertigo, confirmed by a positive Dix–Hallpike test.Methods:One hundred and forty-two patients with posterior semicircular canal benign paroxysmal positional vertigo were interviewed about their past medical history, focusing on factors predisposing to benign paroxysmal positional vertigo. All patients included in the study were able to define a predominant, favourite head-lying side, right or left, during sleep onset.Results:The Dix–Hallpike test was found to be positive on the right side in 82 patients and positive on the left side in 54; six patients were found to be positive bilaterally. During sleep onset, 97 patients habitually laid their head on the right side and the remaining 45 laid their head on the left. The association between the affected ear and the head-lying side during sleep onset was statistically significant (p < 0.001).Conclusions:Our study found a predominance of right-sided benign paroxysmal positional vertigo, a subjective preference amongst patients for a right head-lying position during sleep onset, and an association between the ear affected by benign paroxysmal positional vertigo and the preferred head-lying side during sleep onset. The clinical and therapeutical implications of this observation are discussed.

Paroxysmal Positional Vertigo

Objective: To assess the association between the habitual head position during bedrest and the affected ear in benign paroxysmal positional vertigo (BPPV).Study design: Prospective trial of patients with active BPPV of the posterior semicircular canal, confirmed on physical examination.Methods: Seventy-five patients were asked to explain the head position and lying side they were accustomed to before falling asleep in bed.Results: Fifty patients (67 per cent) habitually adopted a lateral head position during bedrest. The ear affected by BPPV was found to be consistent with the head-lying side during bedrest in 43 cases (86 per cent) (29 cases for the right ear and 14 cases for the left ear).Conclusion: Habitual lateral head-positioning during bedrest can be a major factor leading to the development of BPPV in the ipsilateral ear.
