Disabling positional vertigo.

P J Jannetta, M B Møller, A R Møller

    The New England Journal of Medicine
    |June 28, 1984
    PubMed
    Summary

    A newly identified vestibular disorder causes disabling positional vertigo unresponsive to standard treatments. Microvascular decompression of the eighth nerve provided significant relief, suggesting vascular compression as the cause.

    Area of Science:

    • Neurology
    • Otolaryngology
    • Neurosurgery

    Background:

    • Vestibular disorders encompass various syndromes like Meniere's disease, benign paroxysmal positional vertigo, and vestibular neuronitis.
    • A subset of patients presents with constant positional vertigo and severe nausea, unresponsive to conventional therapies.
    • These symptoms significantly impair daily functioning and are not explained by established vestibular diagnoses.

    Purpose of the Study:

    • To identify the underlying cause of a specific group of patients with disabling positional vertigo.
    • To investigate the potential role of neurovascular compression in these refractory vestibular symptoms.
    • To evaluate the efficacy of microvascular decompression in treating this condition.

    Main Methods:

    • Clinical assessment of patients with unexplained, persistent positional vertigo and nausea.
    • Identification of clinical-pathological signs suggesting intracranial vascular compression of the vestibular nerve.
    • Surgical intervention using microvascular decompression of the eighth cranial nerve in affected patients.

    Main Results:

    • Eight out of nine patients experienced complete symptom resolution following microvascular decompression.
    • One patient showed significant improvement in symptoms after the surgical procedure.
    • The findings strongly indicate a link between eighth nerve compression and the disabling vertigo syndrome.

    Conclusions:

    • A distinct syndrome of disabling positional vertigo, likely caused by eighth nerve vascular compression, has been identified.
    • Microvascular decompression is a highly effective treatment for this specific vestibular disorder.
    • The proposed name for this condition is 'disabling positional vertigo'.
