What is pyriformfossa?

Answer 1

The pyriform fossa, also known as the piriform recess, is a small, pear-shaped space located in the larynx, specifically on either side of the entrance to the esophagus. It is formed by the folds of tissue known as the aryepiglottic folds and is situated above the vocal cords. This structure plays a role in swallowing by helping to direct food and liquids into the esophagus while preventing aspiration into the airway. The pyriform fossa is also clinically significant, as it can be a site for the accumulation of foreign bodies or lesions.
