The human vocal cord is responsible for the production of sound, and it even protects the airway by preventing food, drink and saliva from entering your windpipe, which could cause you to choke.
The paralysis of your vocal cord occurs when the nerve impulses to your larynx, or voice box gets interrupted. Therefore, this then results in the paralysis of the muscle of the vocal cords. The paralysis of your vocal cords can affect your ability to speak and also your ability to breathe. Vocal cord paralysis can cause nerve damage during surgery and in certain cancers. The paralysis can also be caused by a viral infection or certain neurological disorder.
