Anatomical terminology

The pyriform sinus (also piriform recess, piriform sinus, piriform fossa, or smuggler's fossa) is a small recess on either side of the laryngeal inlet. It is bounded medially by the aryepiglottic fold, and laterally by the thyroid cartilage and thyrohyoid membrane.[1] The fossae are involved in speech.
