The cricoid cartilage is a hyaline cartilage ring which fully encircles the trachea and composes the inferior-most boundary of the laryngeal skeleton. The term “cricoid,” (Greek, krikos meaning “ring-shaped”) refers to the signet-ring resemblance of the cricoid cartilage. It has a narrow arch anteriorly, which widens into a broad lamina posterior to the airway. The cricoid cartilage serves to maintain airway patency, forms part of the larynx, and provides an attachment point for key muscles, ligaments, and cartilage, which function in the opening and closing the vocal cords for sound production.[1] Clinically, the cricoid cartilage is an important anatomical landmark for procedures such as cricothyroidotomy, used to establish a viable airway in an emergency setting.
