Vocal cord paralysis is paralysis of the muscles that control vocal cord movement. Vocal cord paralysis can be caused by brain disease, such as brain tumors, stroke, demyelinating disease or laryngeal nerve injury. If recurrent laryngeal nerve on one side is paralyzed, you will have hoarseness, cannot speak, or the air leaks when you speak. If recurrent laryngeal nerves on both sizes are paralyzed, you may have varying degrees of difficulty breathing. If only one side is affected and you have no obvious problems with speaking or breathing, you do not need treatment. If one side is affected but the speaking or breathing function cannot recover after a long time, body fat, collagen or other approved filler substance can be injected under vocal cord mucus membrane. If both sides are affected and you have difficulty breathing, tracheotomy should be done first, followed by surgical correction.
