Pathophysiology of reversible sudden deafness--epidemiological study.

K Ohsaki, H Aoyama

    Acta Medica Okayama
    |April 1, 1983
    PubMed
    Summary

    This study compared tranexamic acid and antisludging agents for sudden deafness, finding both therapies equally effective. Pathophysiology involves vascular permeability, edema, and red blood cell issues due to hypoxia.

    Area of Science:

    • Otolaryngology
    • Vascular Medicine
    • Pharmacology

    Background:

    • The exact causes and mechanisms of reversible sudden deafness are not fully understood.
    • Understanding the pathophysiology is crucial for developing effective treatments.

    Purpose of the Study:

    • To compare the efficacy of two distinct therapeutic approaches for sudden deafness.
    • To gain insights into the underlying pathophysiology of reversible sudden deafness.

    Main Methods:

    • A comparative study involving 49 cases (57 ears) treated with tranexamic acid.
    • Comparison with 65 cases (69 ears) treated with antisludging agents.
    • Statistical analysis using the chi-square contingency test.

    Main Results:

    • Both tranexamic acid and antisludging agents demonstrated similar therapeutic effects.
    • No significant difference in outcomes was observed between the two treatment groups.
    • The differing chemical actions of the therapeutics did not lead to varied results.

    Conclusions:

    • Vascular wall permeability, edema, and extravascular red blood cell oozing due to hypoxia/anoxia are key factors in sudden deafness pathophysiology.
    • These factors contribute to inner ear tissue damage.
    • Further research into these mechanisms may guide future treatment strategies.
