Kehldeckel

Kehldeckel, in medical terms the epiglottis, is a leaf-shaped flap of elastic cartilage covered by mucous membrane that forms part of the larynx. It is located behind the root of the tongue and above the laryngeal inlet, where it can move to cover the glottis. The epiglottis is attached to the inner surface of the thyroid cartilage by the thyroepiglottic ligament and connected to the hyoid bone by the hyoepiglottic ligament, allowing it to move with swallowing.

Anatomically, the epiglottis consists of elastic cartilage, which makes it flexible rather than rigid. Its anterior surface is convex, facing the base of the tongue, while its posterior side faces the laryngeal inlet. The mucous membrane that covers it is continuous with the surrounding pharyngeal and laryngeal mucosa.

Functionally, the epiglottis plays a crucial role in swallowing and airway protection. When swallowing begins, the larynx rises and the epiglottis folds posteriorly to cover the opening of the larynx (the glottis), guiding food and liquid into the esophagus and helping to prevent aspiration. During quiet breathing, the epiglottis remains more upright, allowing air to pass into the larynx and lungs.

Clinical notes include epiglottitis, an acute inflammation of the epiglottis that can threaten the airway and requires urgent medical attention. Vaccination and antibiotics have reduced incidence in children, though adults may present with different symptoms and risks. The term Kehldeckel derives from German, literally meaning throat lid.
