Each segment of the larynx drains to a different sentinel node. The glottis or true vocal cords are not rich in lymphatics and drain to pretracheal or paralaryngeal lymph nodes. The supraglottis is richer in lymphatics and vascularization, with drainage favoring midjugular and jugulodigastric nodes. Subglottic cancers drain to deeper cervical nodes, the jugulo-omohyoid, and even the scalene nodes.
