The aryepiglottic fold is a fold of mucosa forming the lateral border of the laryngeal inlet. It stretches from the apex of the arytenoid cartilage to the epiglottis. The corniculate cartilage and cuneiform cartilages lie under the surface of the free edge posteriorly stiffen and helping shape the upper rim of the epiglottic funnel known as the laryngeal inlet. The fold contains the thin sheets of muscles: the aryepiglotticus and the thyroepiglotticus. The aryepiglottic fold forms the lateral border of the larynx separating it from the piriform fossa of the hypopharynx.
