Supraglottis

Supraglottis extends from tongue base to the valleculae to laryngeal ventricle
Vestibule is the airspace within supraglottic larynx

Epiglottis is a leaf-shaped cartilage that functions as a lid to endolarynx
a. petiole = stem of epiglottis
b. thyroepiglottic ligament = connects petiole to thyroid cartilage inferiorly
c. hyoepiglottic ligament = connects epiglottis to hyoid bone anteriorly, covered by a mucosal fold between the valleculae (glossoepiglottic fold)
d. the free margin  = superior portion of epiglottis


3. False vocal cords,  ventricular folds,  inferior continuation of aryepiglottic folds,  mucosal
surface of ventricular ligaments; forming superior border of laryngeal ventricle

4. Arytenoid cartilages

5. Aryepiglottic folds is the mucosal reflections between cephalad portion (= arytenoid processes) of
arytenoid cartilage + inferolateral margin of epiglottis soft-tissue folds forming border between lateral pyriform sinuses and the central laryngeal lumen

6. Laryngeal ventricle= fusiform fossa bounded by crescentic edge of false cords superiorly +
straight margin of true cords inferiorly, generally not visible on axial scans

7. Preepiglottic space low-density tissue between anterior margin of epiglottis + thyroid
cartilage

8. Paralaryngeal space is a low-density tissue between true + false cords and thyroid cartilage
continuous with preepiglottic space anteriorly + aryepiglottic folds superiorly
