摘要：

In ten patients with bilateral vocal cord paralysis, we demonstrated variable extrathoracic airway obstruction. The ratio of forced expiratory flow at 50 percent vital capacity to forced inspiratory flow at the same lung volume (V(E50)/V(I50)) was 1.65±0.77 (mean±1 SD). There was marked variability of inspiratory flow obstruction with a mean V(I50) of 1.63±0.75 liters/sec and a range from 0.9 liters/sec to 3.2 liters/sec. Nine of the ten patients required tracheostomy for symptoms of dyspnea. Follow-up flow volume loops were obtained to document the effects of surgical intervention and tracheostomy.
