When nerve impulses to your voice box (larynx) are interrupted, vocal cord paralysis occurs. As a result, the vocal cord muscles become paralyzed. The capacity to talk and even breathe can be affected by vocal cord paralysis. This is because your vocal cords, also called vocal folds, are responsible for more than simply sound production. Food, water, and even saliva are prevented from entering your windpipe and choking you. Nerve injury caused by surgery, viral infections, and some malignancies are also possible causes. Surgery and, in certain cases, voice therapy is used to cure vocal cord paralysis. The vocal cords are two flexible bands of muscle tissue located at the windpipe’s aperture (trachea). The bands are coming together and vibrating to make music as you speak. Your vocal cords are relaxed and open the rest of the time, allowing you to breathe. Only one vocal cord is damaged in most cases of vocal cord paralysis. Both of your vocal cords becoming paralyzed is an uncommon but serious ailment. This might result in voice issues as well as breathing and swallowing difficulties. Nerve impulses to your voice box (larynx) are disturbed in vocal cord paralysis, resulting in muscular paralysis. The reason for vocal cord paralysis is usually unknown to doctors. Some possible causes are as follows:
During surgery, the vocal chord was damaged. The nerves that serve your voice box may be damaged during surgery on or near your neck or upper chest. Surgery on the thyroid and parathyroid glands, as well as the esophagus, neck, and chest, all carry the risk of complications.
Injuries to the neck and chest The nerves that serve your vocal cords, as well as the voice box itself, might be injured by trauma to your neck or chest.
Stroke. A stroke disrupts cerebral blood flow, which can harm the part of the brain that sends information to the voice box.
Tumors. Vocal cord paralysis can occur when tumors grow in or near the muscles, cartilage, or nerves that regulate the function of your voice box.
