In suspected acute epiglottitis, which diagnostic test is indicated to assess airway risk?

• A. Chest X-Ray
• B. Complete Blood Count
• C. Nasal Bacterial Culture
• D. Soft Tissue Neck X-Ray

Answer: (D)

Assessing airway risk in suspected acute epiglottitis is best done with a lateral soft tissue neck radiograph, because it directly visualizes swelling around the upper airway without invasive instrumentation. The key finding is the epiglottis appearing enlarged—the classic “thumbprint sign”—which indicates significant edema and a higher risk of airway obstruction. This imaging helps you stratify urgency and plan for airway management while avoiding procedures that could provoke airway collapse. Other tests don’t directly measure airway risk: chest X-ray looks at lungs and mediastinum, not the swollen epiglottis; a complete blood count shows infection markers but not airway patency; a nasal bacterial culture doesn’t inform how open the airway is.
