Subglottis

What is Subglottis?

Subglottis meaning The lowest part of the larynx; the area from just below the vocal cords down to the top of the trachea. The principal lymph node drainage for the larynx is to the internal jugular and anterior cervical nodes. Anterior cervical nodes are the prelaryngeal, pretracheal, paratracheal, and lateral tracheal (recurrent laryngeal) nodes. Bilateral involvement is common, and spread to submandibular and submental nodes may sometimes occur.
