The ventricle of the larynx (also the laryngeal sinus or laryngeal ventricle) is a fusiform fossa, situated between the ventricular and vocal folds on either side, and extending nearly their entire length.

The fossa is bounded, above, by the free crescentic edge of the ventricular fold; below, by the straight margin of the vocal fold; laterally, by the mucous membrane covering the corresponding Thyreoarytænoideus.

The anterior part of the ventricle leads up by a narrow opening into a cecal pouch of mucous membrane of variable size called the appendix.
