Direct thermal trauma is limited to the upper airway and results in obstruction from edema,hemorrhage,and ulceration of the mucosa.In only a few hours,mild pharyngeal edema can rapidly progress to complete upper airway obstruction with asphyxia.The worsening of upper airway edema is most prominent in supraglottic structures.Serial nasopharyngoscopic evaluations demonstrate obliteration of the aryepiglottic folds,arytenoid eminences,and interarytenoid areas by edematous tissue that prolapses and occludes the airway.
