Computed tomography (CT) with contrast demonstrated a hyperdense mass that extended from the right aryepiglottic fold
to the right vocal fold (figure 2).
He was fiberoptically intubated and underwent suspension microlaryngoscopy, which demonstrated a well- circumscribed, encapsulated lesion located in the vallecula and encompassing the right aryepiglottic fold
These margins involved the medial piriform sinus mucosa, the aryepiglottic fold
and corniculate cartilage, and the interarytenoid mucosa.
Laser division of the aryepiglottic folds
for severe laryngomalacia.
The aryepiglottic folds
are thin walls of tissue that extend from the posterior upper larynx to the epiglottis, and these form the medial borders of the pyriform sinuses, which may be elucidated on a swallow study (not shown here).
In the pharyngeal phase, the larynx prevents material from entering the trachea by closing the true vocal cords, false vocal folds and aryepiglottic folds
5) Clinical manifestations include hoarseness, odynophagia, sore throat and dyspnea, while the lesions include inflammatory lesions of the lips, tongue, oral and pharyngeal mucosa, epiglottis, aryepiglottic folds
, vestibular and vocal folds.
2) Lesions are found in the interarytenoid areas and on the aryepiglottic folds
These structures include the aryepiglottic folds
and the loose connective tissues in the pre-epiglottic and para-epiglottic spaces; hence, the alternate term acute supraglottitis.
