    A patient with a hyperactive vestibular response experienced symptom relief through endolymphatic sac shunting and later cryosurgery. Vestibular labyrinth activity correlated with symptom presence, showing hyperactivity when symptomatic and normal or hypoactive when asymptomatic.

    Area of Science:

    • Neurology
    • Otolaryngology
    • Vestibular System

    Background:

    • Vestibular disorders can significantly impact quality of life.
    • Accurate diagnosis and effective treatment of vestibular hyperactivity are crucial.
    • Electronystagmography (ENG) is a key diagnostic tool for assessing vestibular function.

    Observation:

    • A patient presented with documented hyperactive vestibular response via ENG.
    • Initial treatment involved a shunt from the saccus endolymphaticus to the subarachnoid space, providing temporary relief.
    • Recurrent symptoms were managed with cryosurgery to the hyperactive labyrinth, offering longer-term relief.

    Findings:

    • Vestibular labyrinth activity, as measured by ENG, was hyperactive during symptomatic periods.
    • Conversely, vestibular labyrinth activity normalized or became hypoactive when the patient was asymptomatic.

  • Treatment interventions demonstrated efficacy in managing vestibular hyperactivity.

    • Implications:

    • This case highlights the potential of surgical interventions for refractory vestibular hyperactivity.
    • The correlation between ENG findings and symptomatic status underscores the diagnostic value of the test.
    • Understanding the dynamic nature of vestibular activity is important for patient management and treatment strategies.
