Summary
Phrenic nerve grafts may improve airway in bilateral vocal cord paralysis patients without causing diaphragm paralysis. However, vocal cord abduction has not been observed, and reinnervation mechanisms remain unclear.
Area of Science:
- Laryngology
- Neurosurgery
- Respiratory Medicine
Background:
- Bilateral vocal cord paralysis presents significant airway challenges.
- Current treatments may have limitations or side effects.
