Vocal cord paralysis in postpoliomyelitis syndrome
The Laryngoscope
|August 1, 1987
Summary
Postpoliomyelitis syndrome can cause new symptoms like vocal cord paralysis years after polio recovery. This neuromuscular deterioration, while not life-threatening, requires supportive care for polio survivors.
Area of Science:
- Neurology
- Virology
- Immunology
Background:
- Postpoliomyelitis syndrome (PPS) presents with new neuromuscular symptoms years after acute poliomyelitis.
- Poliomyelitis survivors are at risk for developing late-onset neurological deficits.
Observation:
- Bilateral vocal cord paralysis is identified as a novel manifestation of PPS.
- This case report details various clinical features associated with PPS.
Findings:
- The exact etiology of PPS remains unknown, with theories including nerve attrition or immune-mediated destruction.
- Pathological findings reveal scattered muscle fiber atrophy and evidence of chronic denervation and reinnervation.
Implications:
- While not life-threatening, PPS can lead to progressive disability in polio survivors.
- Supportive care for facial, laryngeal, and pharyngeal weakness is essential for managing PPS patients.
