Vocal cord paralysis occurs when the nerve impulses going towards the voice box are disrupted, leading to paralysis. Paralysis of the vocal cord can create problems and difficulties while breathing and speaking. Issues like nerve damage during surgery, viral infections and certain cancers can cause vocal cord paralysis. Damages to the brain can also paralyze the vocal cord. Apart from helping in speech formation, vocal cords prevent the entry of food, drinks and saliva into the windpipe or trachea. Therefore, in critical cases, it can also lead to choking and death.
