His disease was more widespread with most of his airway affected from the base of the epiglottis to the entrance of the right main bronchus.
The opening for air through the larynx is known as the glottis, and the epiglottis , below and behind the tongue, plays a necessary part in closing off the glottis during swallowing.
The instrument is introduced orally and advanced to the epiglottis , where it is rotated 90 degrees to pass the vocal cords and enter the trachea.
The epiglottis and tumours arising from it are composed of fibroelastic cartilage.
The characteristic barking cough of croup is uncommon in epiglottitis and, in cases of croup, the epiglottis is not as inflamed and edematous.
In some cases, such as when the swollen epiglottis blocks the windpipe, a tracheostomy may be performed.
It is particularly important to understand the relationship of the following structures: the epiglottis , arytenoid cartilage, aryepiglottic folds, and cricoid cartilage.
Some afferent fibres from the epiglottis , palate and pharynx also reach the brainstem via the vagus nerve.
An alternative technique, as used in adults, is to insert the tip of the blade into the vallecula at the base of the epiglottis (further than shown in the diagram), which lifts the epiglottis to reveal the vocal cords beneath.
The epiglottis is moved over the laryngeal inlet.
