vocal cord paralysis
Loss of vocal cord movement due to recurrent laryngeal nerve injury during thyroid surgery.
Full Definition
A significant complication of thyroid and parathyroid surgery resulting from injury to the recurrent laryngeal nerve, leading to immobility of the affected vocal cord. This condition can manifest as hoarseness, breathy voice quality, aspiration risk, and reduced vocal projection. The paralysis may be temporary due to nerve neuropraxia or permanent due to nerve transection. Bilateral vocal cord paralysis is a surgical emergency requiring immediate airway management, while unilateral paralysis may improve over time or require voice therapy or surgical intervention for voice rehabilitation.
Usage
Usage note: Distinguish severity: unilateral vs. bilateral, temporary vs. permanent.
