Left vocal cord paralysis  (Abductor Muscle - Raspy Voice) This video shows the function of a larynx from a 35 year old white female with a left true vocal cord paralysis.  The paralysis occurred after the removal of a mediastinal mass involving the aortic arch.  Note that the cord is lateral (away from the midline of the larynx) and bowed.  The voice is hoarse but only mildly weakness is present since the patient has partially compensated.
