Large perilymph fistulas can cause recurrent meningitis. Surgical obliteration of the vestibule, not just fistula closure, is recommended for effective prevention.
Area of Science:
- Otolaryngology
- Neurology
- Pediatrics
Background:
- Perilymph fistulas (PLFs) can present with otologic or neurologic symptoms.
- Large PLFs are often associated with significant neurologic manifestations.
Observation:
- A case of a 3-year-old girl with recurrent bacterial meningitis was investigated.
- The patient exhibited a large perilymph fistula with a right undeveloped cochlea and labyrinth.
- Multiple defects were noted in the medial wall of her middle ear.
Findings:
- Recurrent meningitis in this case was linked to a large congenital perilymph fistula.
- Simple fistula closure was deemed insufficient for preventing recurrent meningitis.
- Surgical obliteration of a deeper structure, specifically the vestibule, was identified as the preferred method.
Implications:
- This case highlights the critical link between large PLFs and recurrent meningitis.
- Effective management of large congenital PLFs requires more than simple fistula repair.
- Vestibular obliteration is proposed as the surgical method of choice for preventing recurrent meningitis in such cases.
Abstract:
Perilymph fistulas may manifest themselves either by otologic symptoms, as in cases of small fistulas, or primarily through neurologic symptoms, as with large fistulas. A case history is presented of a 3-year-old girl with recurrent bouts of meningitis who was found to have a large perilymph fistula. She had a right undeveloped cochlea and labyrinth, as well as multiple defects of the medial wall of her middle ear. The only way of preventing the recurrent bouts of bacterial meningitis in cases of large perilymph fistulas is surgical repair. Our conclusion is that, considering the problems involved in cases of large congenital perilymph fistulas, a simple closure of the fistula is not sufficient and the method of choice is obliteration of a deeper structure--such as the vestibule itself.
