Vestibular evoked myogenic potential (VEMP) testing revealed saccular dysfunction in 54% of Meniere

Area of Science:

  • Neuroscience
  • Otolaryngology
  • Vestibular System Research

Background:

  • Meniere's disease is a disorder of the inner ear.
  • Saccular dysfunction is a potential component of Meniere's disease.

Purpose of the Study:

  • To evaluate saccular function in unilateral Meniere's disease using vestibular evoked myogenic potentials (VEMPs).
  • To correlate VEMP results with audiometric and caloric test findings.
  • To assess the impact of saccular dysfunction on postural stability.

Main Methods:

  • Retrospective analysis of 59 patients with unilateral Meniere's disease.
  • Recording of cervical VEMPs elicited by high-level clicks.
  • Audiometric and bithermal caloric testing.
  • Postural performance analysis using Equitest for a subset of patients.

Main Results:

  • Saccular response was absent in 54% of patients on the affected side.
  • Absence of saccular response correlated with low-frequency hearing loss, not canal paresis.
  • Patients with saccular dysfunction exhibited poorer postural performance.

Conclusions:

  • Saccular dysfunction is prevalent in Meniere's disease.
  • VEMP testing is valuable for identifying patients with saccular impairment.
  • Assessing dynamic postural performance on a movable platform is recommended for patients with saccular lesions to guide vestibular rehabilitation.
