Cochlear and vestibular dysfunction resulting from physical exertion or environmental pressure changes.

A Katsarkas, J D Baxter

    The Journal of Otolaryngology
    |February 1, 1976
    PubMed
    Summary

    Inner ear damage from exertion or pressure changes can occur via explosive or implosive mechanisms. Diagnosis involves history, audiogram, and ENG, with treatment remaining controversial.

    Area of Science:

    • Otolaryngology
    • Neurology
    • Auditory Medicine

    Background:

    • Recent literature describes inner ear damage resulting from physical exertion or environmental pressure fluctuations.
    • Two primary injury mechanisms are proposed: explosive (increased cerebrospinal fluid pressure) and implosive (increased middle ear pressure).

    Observation:

    • Sudden hearing loss and/or dizziness are the principal symptoms.
    • Diagnosis relies on a comprehensive patient history, audiogram results, and electronystagmography (ENG).

    Findings:

    • The underlying mechanisms involve pressure transmission to the inner ear's perilymph space.
    • A perilymph fistula is a potential complication, necessitating careful evaluation.

    Implications:

    • Treatment strategies for this condition are currently debated and not standardized.
    • Individualized patient assessment is crucial due to symptom variability.
    • Exploratory tympanotomy may be indicated in suspected cases to rule out fistula formation.
