The paired laryngeal cartilages are the arytenoid, cuneiform and lesser horn cartilages. Among them, the cuneiform cartilage and the small horn cartilage are very small in size and of little clinical significance. 1. Arytenoid cartilage: located above the cricoid cartilage plate, three-pronged cone. The bottom and the upper edge of the cricoid cartilage form the cricoarytenoid joint. At the bottom of the cartilage, there are two protrusions, the forward protrusion is called the vocal cord protrusion, attached to the vocal ligament; the lateral protrusion is called the muscle protrusion, attached to the laryngeal muscle. 2. Cuneiform cartilage: It is located under the mucosa of the arytenoid folds on both sides and leads to the formation of a bulge in the mucosa, which is called a cuneiform nodule. The cartilage is also located lateral to the lesser horn cartilage on both sides. These two cartilages can be absent in some populations. 3. Lesser navicular cartilage: On top of the arytenoid cartilage, the main function is to stretch the folds. For people with laryngeal discomfort, they should go to the relevant departments of regular hospitals as soon as possible to improve the relevant examinations, and be treated by professional physicians after a clear diagnosis, so as not to delay the condition and lead to adverse results.
