laryngeal sinus
laryngeal ventricle

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

Laryngeal saccules or laryngeal ventricles are soft tissue masses located between the vocal folds and the lateral wall of the larynx in canines.

It may also be acquired, seen in glassblowers due to continual forced expiration producing increased pressures in the larynx which leads to dilatation of the laryngeal ventricle.

The appendix of the laryngeal ventricle (laryngeal saccule, laryngeal pouch or Hilton's pouch) is a diverticulum (membranous sac) which extends vertically from the ventricle of the larynx.
