flexibility of its structure, which is composed ofelastic cartilage, and its muscular and ligamentous connections to the aryepiglottic folds and the true and false vocal cords that close the airway.2However, when it fails to retroflex it may become obstructive rather than protective. Abnormal ...
The epiglottis sits at the entrance of the larynx. It isshaped like a leaf of purslaneand has a free upper part that rests behind the tongue, and a lower stalk (Latin: petiolus). The stalk originates from the back surface of the thyroid cartilage, connected by a thyroepiglottic ligamen...
epiglottic cartilageepiglottic closureepiglottisObjectives: We conducted a histologic examination and measured the tension on the epiglottis to determine how dehiscence of the epiglottis can be prevented after epiglottic closure surgery. Methods: We classified configurations of the epiglottis into flat, ...
Obstruction of the laryngeal inlet by the epiglottis leads to a condition known as floppy epiglottis (FE), in whichthe epiglottis is sucked into the laryngeal inlet during inspiration. Although FE in infants is caused by a congenital abnormality in the laryngeal cartilage,2the mechanism of FE in...
The function of the epiglottis in adult is unclear. However, during early infancy the epiglottic cartilage appears to play an important role in separating the upper respiratory tract from the upper digestive tract. This separation is acc... CT Sasaki,PA Levine,JT Laitman,... - 《Archives of...

The system employs a convolutional neural network, the YOLOv4 model, for epiglottis cartilage localization, a color quantization method to transform pixels into regions, and a region puzzle algorithm to calculate the range of a patient’s epiglottis airway. This information is then utilized to ...
