Bilateral Vocal Cord Paralysis  (Adductor Muscle Paralysis - Weak Breathy Voice) This video shows the function of a larynx from a 51 year old white female with a bilateral true vocal cord paralysis.  The patient was a non-smoker and has Lupus Erythematosus.  Her voice is weak but has a good airway.  Three years ago she had a transient left true vocal cord paralyses which lasted for three weeks.  Notice that her true vocal cords stay apart but the apices of the arytenoid cartilages make contact.  There is even a contact ulcer forming on the apex of the left artyenoid cartilage.  The paralysis resolved 2 weeks later.
