Causes Injury to the laryngeal nerves is uncommon.When it does occur, it can be from:A complication of neck or chest surgery (especially thyroid, lung, heart surgery, or cervical spine surgery) A breathing tube in the windpipe (endotracheal tube) A viral infection that affects the nerves Tumors in the neck or upper chest, such as thyroid or lung cancer ThyroidThyroid cancer is a cancer that starts in the thyroid gland.

In some cases, no treatment may be needed and the nerve may recover on its own. Voice therapy is useful in some cases.If surgery is needed, the goal is to change the position of the paralyzed vocal cord to improve the voice. This can be done with:Arytenoid adduction (stitches to move the vocal cord toward the middle of the airway) Injections of collagen, Gelfoam, or another substance Thyroplasty If both the left and right nerves are damaged, a hole may need to be cut into the windpipe (tracheotomy) right away to allow breathing. This is followed by another surgery at a later date. Outlook (Prognosis) The outlook depends on the cause of the injury. In some cases, the nerve rapidly returns to normal. However, sometimes the damage is permanent.
