Vocal cord paralysis happens once the nerve impulses to your vocal organ (larynx) ar disrupted. This ends up in paralysis of the vocal fold muscles.
Vocal cord paralysis will have an effect on your ability to talk and even breathe. That's as a result of your vocal cords, typically known as vocal folds, do quite simply produce sound.
They also defend your airway by preventing food, drink and even your spit from entering your windpipe (trachea) and inflicting you to choke.
