A small bursa at the petiole (narrow inferior stalk) of the epiglottis where it attaches to the thyroid cartilage notch via the thyroepiglottic ligament, reducing friction during laryngeal elevation in swallowing.
The epiglottic petiole attachment is the surgical target in endoscopic supraglottic resections where the epiglottis is divided at its stalk. Epiglottitis most severely affects the epiglottic petiole region where oedema produces the characteristic thumbprint sign on lateral neck X-ray. Petiole fracture occurs in direct laryngeal trauma.
Acute bacterial oedema at the epiglottic petiole producing the thumbprint sign on lateral neck X-ray and life-threatening airway obstruction requiring emergency airway management.
