The epiglottic valleculae are paired spaces between the root of the tongue and anterior surface of the epiglottis. Each vallecula is bordered medially by the median glossoepiglottic fold and laterally by the lateral glossoepiglottic fold. The valleculae can collect saliva to prevent initiation of the swallowing reflex.
The epiglottis and vallecula are important anatomical landmarks in intubation. [13] Abnormal positioning of the epiglottis is a rare cause of obstructive sleep apnoea.
Laryngeal cysts are cysts involving the larynx or more frequently supraglottic locations, such as epiglottis and vallecula. [1] Usually they do not extend to the thyroid cartilage. [2] They may be present congenitally [3] or may develop eventually due to degenerative cause. [4] They often interfere with phonation.
In front, they are bounded by the epiglottis. Behind, they are bounded by the apices of the arytenoid cartilages , the corniculate cartilages , and the interarytenoid notch. [ 2 ] Within the posterior part of each aryepiglottic fold exists a cuneiform cartilage which forms a whitish prominence, the cuneiform tubercle.
The flap of cartilage called the epiglottis stops food from entering the larynx. In humans, the pharynx is part of the digestive system and the conducting zone of the respiratory system . (The conducting zone—which also includes the nostrils of the nose , the larynx , trachea , bronchi , and bronchioles —filters, warms and moistens air and ...
It is clinically important in performing direct laryngoscopy with a Macintosh laryngoscope blade; the blade tip is placed in the vallecula and moved anteriorly, which causes the hyoepiglottic ligament to pull the epiglottis anteriorly as well and thus expose the glottis. [citation needed]
straight mirror for indirect laryngoscopy (seeing the larynx); structure seen are the base of tongue, vallecula, glossoepiglottic fold, epiglottis, pharyngo-epiglottic folds, aryepiglottic folds, epiglottis, interarytenoid region, pyriform sinus, inlet of larynx, supraglottic region, ventricular bands, vocal cord, subglottis and few rings of ...
The anterior or lingual surface of the epiglottis is curved forward, and covered on its upper, free part by mucous membrane which is reflected on to the sides and root of the tongue, forming a median and two lateral glossoepiglottic folds; the lateral folds are partly attached to the wall of the pharynx.
