Which sign is most consistent with tracheobronchial rupture/laceration?

• A. Severe respiratory distress
• B. Stridor, hoarseness (if able to talk)
• C. Subcutaneous crackling sensations to touch
• D. Decreased or unequal breath sounds

Answer: (C)

Air leaking from a torn trachea or main bronchus into the soft tissues around the neck and chest causes subcutaneous emphysema, which you can feel as a crackling sensation under the skin when you palpate. This palpable crepitus is a classic, highly specific sign of tracheobronchial rupture after trauma because it directly reflects air escaping into tissues rather than remaining in the airway. Other signs like severe respiratory distress, stridor/hoarseness, or unequal breath sounds can occur with a range of chest injuries and aren’t as specific to this injury. So the presence of subcutaneous crackling sensations to touch best aligns with a tracheobronchial rupture.
