Brainstem evoked response audiometry in confirmed eighth nerve tumors

A F Josey, C G Jackson, M E Glasscock

    American Journal of Otolaryngology
    |August 1, 1980
    PubMed
    Summary

    Brainstem evoked response audiometry effectively predicts eighth nerve disease. In 52 tumor cases, this audiology test correctly identified lesions in 51 patients, proving its value in diagnostic testing.

    Area of Science:

    • Neurology
    • Audiology
    • Neurosurgery

    Background:

    • Eighth nerve diseases, including tumors, can cause significant auditory and neurological deficits.
    • Accurate diagnosis and localization of these lesions are crucial for effective treatment planning.

    Purpose of the Study:

    • To evaluate the efficacy of brainstem evoked response audiometry (BERA) in diagnosing eighth nerve and cerebellopontine angle tumors.
    • To assess the correlation between BERA findings and surgically confirmed diagnoses.

    Main Methods:

    • Retrospective analysis of audiology findings in 52 patients with surgically confirmed eighth nerve or cerebellopontine angle tumors.
    • Detailed review of brainstem evoked response audiometry results for each case.

    Main Results:

    • Brainstem evoked response audiometry results were consistent with an eighth nerve lesion in 51 out of 52 cases (98% accuracy).
    • The study demonstrated a high concordance between BERA findings and the presence of surgically confirmed tumors.

    Conclusions:

    • Brainstem evoked response audiometry is a highly effective and reliable tool for predicting eighth nerve disease.
    • The study strongly recommends the use of BERA in diagnostic protocols for suspected eighth nerve and cerebellopontine angle lesions.
