Laryngeal paralysis refers to paralysis of the muscles of the larynx that normally contract and expand during breathing. Postoperative laryngeal paralysis may be associated with thyroid surgery. Laryngitis, which may occur as a result of excessive smoking, can lead to permanent voice changes.
The voice box, or larynx, houses two elastic vocal cords atop the windpipe. The cords close when people swallow, protecting the airway. They open when people breathe. And they come together and vibrate when people speak or sing. Paralysis or weakness of a vocal cord can occur when the nerve that supplies it is damaged. This nerve, the recurrent laryngeal nerve, is famously circuitous, looping down into the chest before heading back up to the voice box.
