The two laryngeal nerves attach to the larynx, commonly called the voice box. They help move the vocal cords, which allows a person to talk, and they also help prevent food or liquid from getting into the trachea, or windpipe. Laryngeal nerve damage can result from a few different medical conditions and has varying symptoms.
Causes
Laryngeal nerve damage can be caused by a complication from surgery, particularly surgery involving the heart, thyroid or lungs. It also can result from a breathing tube in the windpipe, or tumors or other growths.
Throat Symptoms
Laryngeal nerve damage symptoms include difficulty speaking or swallowing, and hoarseness.
Respiratory Symptoms
Additional symptoms include difficulty breathing and shortness of breath.
Dangerous Symptoms
Dangerous symptoms include inhalation of food or liquid into the lungs, which can cause aspiration pneumonia.
Treatment
In some cases, the nerve recovers on its own, but sometimes the damage is permanent. Surgery may be needed, and some people need voice therapy.
