Laryngeal nerve damage is injury to one or both of the nerves that are attached to the voice box.
Injury to the laryngeal nerves is uncommon.
However, it may occur as a complication of neck or chest surgery (especially thyroid, lung, or heart surgery) or as a result of a breathing tube in the windpipe (endotracheal tube).
Laryngeal nerve damage may also occur from tumors in the neck or upper chest, such as thyroid or lung cancer.
