Paroxysmal Positional Vertigo

ABSTRACT This article reviews the causes of positional vertigo and positional nystagmus of peripheral origin. Benign paroxysmal positional vertigo is described in all its variants, its diagnosis and therapy are highlighted. In addition, nonparoxysmal positional vertigo and nystagmus due to light/heavy cupula of lateral and posterior semicircular canal is focused on. The differential diagnosis between positional vertigo due to otolithic and nonotolithic causes is discussed. How to cite this article Asprella Libonati G.

Paroxysmal Positional Vertigo

This case study describes transient downbeat nystagmus with vertigo due to a bilateral Bow Hunters Syndrome that was initially treated for 7 months as a peripheral benign paroxysmal positional vertigo. Normal static angiography and imaging studies (magnetic resonance, computed tomography) contributed to the mis-diagnosis. However, not until positional testing with the patient in upright (non-gravity dependent) was a transient downbeat nystagmus revealed with vertigo. The patient was referred for neurosurgical consult. Unfortunately, surgery was delayed due to suicidal ideation and hospitalization. Eventually, vertigo symptoms resolved following a C4-5 anterior cervical dissection and fusion. This case highlights the critical inclusion of non-gravity dependent position testing as an augment to the positional testing component of the clinical examination as well as the extreme duress that prolonged positional vertigo can cause.

Paroxysmal Positional Vertigo

Purpose The purposes of this article are (a) to describe the different test procedures for benign paroxysmal positional vertigo (BPPV) and (b) to provide guidance for the treatment of the various forms of BPPV and to discuss the efficacy of the different interventions. Conclusions While BPPV primarily occurs in the posterior semicircular canal, it is also seen in the anterior and horizontal semicircular canals. There are distinctive patterns of nystagmus that help identify the affected semicircular canal and to differentiate between cupulolithiasis and canalithiasis forms of BPPV. There is reasonable evidence to support the different treatments for both posterior and horizontal semicircular canal BPPV. Anterior semicircular canal BPPV is rare, and as a consequence, there is little evidence to support the various treatment techniques. Finally, while BPPV is generally easy to identify, there are central causes of positional nystagmus with and without vertigo, which can complicate the diagnosis of BPPV. The signs and symptoms of BPPV are contrasted with those of the central causes of positional nystagmus.

Paroxysmal Positional Vertigo

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. Cases of multiple-canal BPPV have been specifically investigated because until recently these were resistant to treatment with standard canalith repositioning procedures. Probably, the most significant factor in diagnosis of the type of BPPV is observation of the provoked nystagmus, during the diagnostic positional maneuvers. We describe in detail the various types of nystagmus, according to the canals involved, which are the keypoint to accurate diagnosis.

Objective: Describe the diagnosis, treatment, and outcome of a group of 20 patients with lateral semicircular canal benign paroxysmal positional vertigo (LSC-BPPV). Study Design and Setting: Retrospective review of 20 patients with LSC-BPPV (10 with geotropic and 10 with apogeotropic nystagmus) presenting to a tertiary balance center. Diagnosis was confirmed with infrared nystagmography in Dix-Hallpike positioning tests and supine positional tests. Patients were treated with one or more particle repositioning maneuvers. Results: Addition of supine positional nystagmus tests to Dix-Hallpike positioning testing improves sensitivity in the diagnosis of LSC-BPPV. Treatment outcomes in the apogeotropic LSC-BPPV group were poorer than the geotropic LSC-BPPV group. Significance: Adding supine positional testing to routine vestibular diagnostic testing will increase the identification of LSC-BPPV. Apogeotropic LSC-BPPV is more challenging to treat.
