Laryngeal Paralysis

If one vocal cord is paralyzed, it will often cause a breathy voice. This can happen for no obvious reason, from surgeries in the neck such as thyroid or spine or from tumors in the neck, chest, or brain. It can be treated with several different procedures, some of which are more temporary than others. Both vocal cords can also become paralyzed, which, in some cases, can make it difficult to breathe.
