What are early signs of airway compromise in facial trauma that require urgent intervention?

• A. Stridor, hoarseness, increasing work of breathing, decreasing oxygen saturation, facial swelling, subcutaneous emphysema.
• B. Cough without respiratory distress
• C. Normal breath sounds with stable oxygen saturation
• D. Minimal facial swelling with no airway signs

Answer: (A)

Recognizing when the airway is becoming compromised in facial trauma hinges on noticing signs that the airway is narrowing or malpositioned and the patient is starting to struggle to breathe. Stridor is a high-pitched sound coming from turbulent airflow, typically signaling narrowing at the larynx or upper trachea. Hoarseness points to injury or edema of the vocal cords, which can herald evolving airway swelling. An increasing work of breathing shows the patient is actively tiring to maintain ventilation. A drop in oxygen saturation confirms that gas exchange is being impaired. Facial swelling and subcutaneous emphysema reflect local trauma and air tracking into tissues, both of which raise the risk of obstruction progressing.

When these signs appear, they indicate an urgent need to secure the airway and be prepared for a potentially difficult intubation or transition to a definitive airway. Quick action helps prevent complete obstruction and hypoxia. In contrast, coughing without distress, normal breath sounds with stable oxygen saturation, or minimal facial swelling with no airway signs do not signal an immediate airway threat.
