Pyriform Sinus Definition

Back 23

A subsite of the hypopharynx. It is a cone shaped structured covering the posterior 3rd of the larynx. The wide end is at the level of the hyoid and the narrow apex is near the middle of the cricoid. There is no barrier to tumor spread here. The apex level on CT scan is the cricoarytenoid joint.
