Stapedectomy and fatal meningitis. A human temporal bone study.

J T Benitez

    ORL; Journal for Oto-Rhino-Laryngology and Its Related Specialties
    |January 1, 1977
    PubMed
    Summary

    A stapes surgery complication led to acute otitis media, labyrinthitis, and meningitis. Purulent exudate spread via the oval window and vestibular nerve pathways, resulting in patient death.

    Area of Science:

    • Otolaryngology
    • Neuropathology
    • Infectious Disease

    Background:

    • Stapes surgery is a common procedure for hearing restoration.
    • Complications, though rare, can include inner ear and central nervous system infections.

    Observation:

    • A patient developed acute suppurative otitis media, labyrinthitis, and meningitis post-stapes surgery.
    • Temporal bone histopathology revealed purulent exudate invasion through a displaced footplate at the oval window.

    Findings:

    • The primary route of infection to the meninges was identified as extension along vestibular nerve branches.
    • Infection spread from the middle ear to the internal auditory meatus and subsequently to the subarachnoid space.

    Implications:

    • This case highlights the critical risk of central nervous system infection following middle ear surgery.
    • Understanding infection pathways is crucial for preventing severe outcomes in otologic procedures.
