What causes vocal fold paralysis?
Vocal fold paralysis is caused by head and neck injuries, tumors, disease, surgery, or stroke. The vagus nerve has branches that run from the brainstem to the larynx (voicebox) and controls the movement of the vocal folds. Damage to the vagus nerve is the specific cause of vocal fold paralysis.
