A protruding laryngeal node may not be a normal clinical manifestation, but there are the following cases: the first is thyroid disease, some patients have adenoma, goiter, thyroid abscess, etc., which can manifest as a localized bulge of the thyroid gland. This is a congenital disease that occurs clinically above and below the hyoid body, but also below the laryngeal node, which is not very common. The third type is that some patients have enlarged lymph nodes in front of the larynx, which can be caused by inflammatory infections in the throat or by advanced metastasis of hypopharyngeal or laryngeal cancer. The fourth type is that some patients have pre-cervical subcutaneous lipomas, sebaceous cysts and other related diseases, which also have this manifestation.
