The aryepiglottic folds are triangular folds of mucous membrane of the larynx. They enclose ligamentous and muscular fibres. They extend from the lateral borders of the epiglottis to the arytenoid cartilages, hence the name 'aryepiglottic'. They contain the aryepiglottic muscles and form the upper borders of the quadrangular membrane.

The aryepiglottic folds are folds of mucous membrane that extend from the side of the epiglottis to the arytenoid cartilages in the larynx. They form the upper borders of the quadrangular membrane. Understanding the anatomy of this region helps in comprehending its functions and the potential issues that can arise.

The aryepiglottic folds mark the lateral borders of the laryngeal inlet 2 and are therefore a critical structure for anesthesiologists when performing direct laryngoscopy 3.

The aryepiglottic fold is a fold of mucous membrane forming the lateral border of the laryngeal inlet, which contains ligamentous and muscular fibers. The ligamentous fibers are the free superior edge of the quadrangular membrane known as the aryepiglottic ligament , which comprises the central component of the aryepiglottic fold and connects ...

The aryepiglottic folds are the soft tissues that extend from the epiglottis anterosuperiorly to the arytenoid cartilage posteroinferiorly and normally are convex downward. From: Pediatric Imaging, 2009
