Epiglottic vallecula

The epiglottic vallecula is a small depression located at the base of the tongue, in the oropharynx region of the throat. It is an important anatomical structure that plays a crucial role in swallowing and protecting the airway during the process.

Anatomy

The epiglottic vallecula is situated between the base of the tongue and the epiglottis, which is a leaf-shaped cartilage that covers the entrance to the larynx during swallowing. It is a shallow groove that runs longitudinally and is lined with mucous membrane.

Function

The primary function of the epiglottic vallecula is to collect and direct food and liquid towards the esophagus during swallowing. When we swallow, the epiglottis closes off the entrance to the larynx, preventing food and liquid from entering the airway. The vallecula acts as a reservoir, allowing the food to be temporarily stored before being pushed down into the esophagus.

Clinical Significance

The epiglottic vallecula can be affected by certain medical conditions. One such condition is vallecular cyst, which is a benign growth that can develop in the vallecula. Vallecular cysts are usually asymptomatic but can cause difficulty in swallowing or breathing if they grow large enough. Treatment options for vallecular cysts include observation, aspiration, or surgical removal.
