Definition:

Bilateral vocal fold (cord) immobility (BVFI) is a broad term that refers to all forms of reduced or absent movement of the vocal folds. Bilateral vocal fold (cord) paralysis (BVFP) refers to the neurologic causes of BVFI and specifically refers to the reduced or absent function of the vagus nerve or its distal branch, the recurrent laryngeal nerve (RLN). Vocal fold immobility may also result from mechanical derangement of the laryngeal structures, such as the cricoarytenoid (CA) joint.
