aryepiglottic

Aryepiglottic refers to the structures surrounding the upper part of the larynx that connect the epiglottis to the arytenoid cartilages. The aryepiglottic folds are paired mucosal folds extending from the apex of each arytenoid cartilage to the lateral edge of the epiglottis. They form the upper boundary of the laryngeal inlet and are continuous with the epiglottis and the arytenoid region, merging with the margins of the quadrangular membrane.

Within each fold lies the musculus aryepiglotticus, a short intrinsic laryngeal muscle. The folds also carry the mucosa and associated connective tissue that contribute to the architectural integrity of the laryngeal inlet. Together with the epiglottis and neighboring membranes, the aryepiglottic folds participate in shaping and narrowing the inlet during swallowing.

Functionally, the aryepiglottic folds help protect the airway by assisting in the closure and inward movement of the laryngeal inlet during swallowing, and they contribute to the coordination of epiglottic movement. Clinically, they are visible landmarks in laryngoscopy and imaging. Pathologies such as thickening or lesions involving the aryepiglottic folds can occur in laryngeal disease, including tumors, and may affect airway protection and swallowing.
