Stapedectomy and fatal meningitis. A human temporal bone study
Abstract:
Temporal bone histopathology is reported on a case of acute suppurative otitis media, acute suppurative labyrinthitis, and meningitis with death of the patient 20 days after stapes surgery. Purulent exudate invaded the vestibule by the oval window through a displaced footplate. The main pathway of infection to the menings was extension along the branches of the vesticular nerve to the internal auditory meatus and to the subarachnoid space.
Insights
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.
