hyoepiglottic

Hyoepiglottic refers to a ligamentous connection between the epiglottis and the hyoid bone, most commonly described as the hyoepiglottic ligament (ligamentum hyoepiglotticum). It is part of the laryngeal skeleton and helps support the epiglottis in its position relative to the airway and digestive tract.

Anatomy and relationships: The hyoepiglottic ligament extends from the epiglottis to the hyoid bone, forming the hyoepiglottic fold with surrounding mucosa. It lies alongside other laryngeal ligaments, such as the thyroepiglottic ligament, which connect the epiglottis to the thyroid cartilage, together stabilizing the epiglottis during movement of the larynx.

Function: The ligament anchors the epiglottis to the hyoid region, allowing controlled movement of the epiglottis during swallowing. By helping to position and stabilize the epiglottis, it aids in closing the laryngeal inlet to prevent aspiration as the airway is protected during the transit of food and liquid.

Clinical significance: The hyoepiglottic connection is a normal anatomical feature that supports swallowing and airway protection. While not typically a focal point of clinical procedures, understanding its role can be relevant in assessments of laryngeal mechanics, swallowing disorders, or during imaging and surgical planning involving the epiglottis and hyoid region.

Etymology and terminology: The name reflects its paired association with the hyoid bone and the epiglottis, and it is commonly referred to in anatomical texts as the hyoepiglottic ligament or hyoepiglottic fold.
