Epiglottis, Superior View

Description

Superiorly oriented laryngeal anatomy is centered on the epiglottis, a leaf-shaped elastic cartilage that sits posterior to the tongue base and anterior to the laryngeal inlet. The median glossoepiglottic fold and paired lateral glossoepiglottic folds tether its lingual surface, creating the valleculae between the tongue and epiglottis. Laterally, the aryepiglottic folds outline the margins of the laryngeal aditus, while the superior aspect of the thyroid cartilage contributes to the surrounding framework. Orientation is clear: tongue and vallecula lie anterior, the laryngeal vestibule and airway lie posterior and inferior. This superior perspective matters because it matches what clinicians see during direct or video laryngoscopy, where the epiglottis can be the dominant landmark and also a frequent obstacle. A long, floppy epiglottis or lingual tonsil hypertrophy can obscure the glottic opening, and inflammation (epiglottitis) produces rapid supraglottic swelling that threatens airway patency. Understanding how the vallecula relates to the epiglottis also guides blade placement, since the Macintosh blade typically seats in the vallecula to indirectly elevate the epiglottis and expose the laryngeal inlet.
