A Superior View of the Thyroepiglottic Ligament of a Male

Description

Viewed from above into the laryngeal inlet, the epiglottis lies anteriorly as a leaf shaped cartilage, with its base tethered inferiorly toward the thyroid cartilage by the thyroepiglottic ligament. Posterior to the epiglottis, the arytenoid cartilages sit on the superior margin of the cricoid, flanking the interarytenoid region and anchoring the posterior ends of the vocal folds. The true vocal cords extend anteromedially from the vocal processes of the arytenoids toward the anterior commissure at the inner surface of the thyroid cartilage, with adjacent laryngeal musculature framing the glottic opening. Orientation is intuitive. A superior perspective is the one most clinicians mentally reconstruct during flexible fiberoptic laryngoscopy, when the epiglottis can obscure the anterior commissure and subtle changes in the supraglottic soft tissues alter the airway aperture. Tension and position of the arytenoids and vocal folds in this view matter for differentiating functional dysphonia from structural problems such as vocal fold paralysis, arytenoid dislocation after intubation, or edema of the epiglottic base in acute supraglottitis. The thyroepiglottic ligament is also a useful landmark when teaching how the epiglottis couples to the thyroid cartilage during swallowing and phonation. Use this artwork in gross anatomy and head and neck modules to bridge cartilaginous framework with phonatory biomechanics, and in otolaryngology teaching materials that pair endoscopic photos with a labeled anatomic map of the laryngeal inlet. It also supports figures for anesthesia and airway management texts covering intubation related injury patterns around the arytenoids and anterior commissure.
