The laryngeal saccules are soft tissue masses that are extensions of the laryngeal ventricles in the larynx. Their function is not well understood, but they may lubricate the vocal cords, and increase the resonance of vocalisation. They may be involved in airway disease and airway obstruction. They may be surgically removed using a laryngeal sacculectomy.
The function of the laryngeal saccules is not well understood. They may help to lubricate the vocal cords, with the contraction of surrounding muscles increasing mucus secretion. In other animals (such as primates), they may increase the resonance of vocalisation.
