Cross Section of the Larynx Showing the Hyoepiglottic Ligament, Lateral View

Description

Cut through in lateral cross section, the male larynx is opened to the pre-epiglottic region where the hyoepiglottic ligament runs from the anterior surface of the epiglottic cartilage to the body of the hyoid bone. Superiorly, the epiglottis rises behind the tongue base, while inferiorly the thyroid cartilage and cricoid cartilage form the anterior and lateral walls of the airway as it continues into the proximal trachea. The ligament sits anterior to the laryngeal inlet and deep to the infrahyoid strap muscle plane, acting as a fibrous tether that limits posterior displacement of the epiglottis during swallowing. Clear relationships. No guesswork. Lateral appreciation of the hyoepiglottic ligament matters when teaching the mechanics of epiglottic inversion and the way the pre-epiglottic space is defined for surgery and staging. Tumor spread in supraglottic laryngeal carcinoma often tracks through the pre-epiglottic fat and along ligamentous attachments, and this tether helps explain why lesions of the epiglottis can present with altered airway protection and dysphagia rather than early voice change. Surgeons rely on these planes during endoscopic supraglottic laryngectomy and when navigating around the superior laryngeal neurovascular bundle in adjacent tissue. Use this illustration in head and neck anatomy courses to anchor the soft tissue attachments that are hard to infer from isolated cartilage diagrams, and in ENT or speech-language pathology teaching materials that link ligament anatomy to aspiration risk and swallow rehabilitation targets. It also fits radiology or pathology texts that correlate supraglottic compartments on CT or MRI with routes of spread in epiglottic and vallecular disease.
