Retropharyngeal Subcutaneous Emphysema Leading to Airway Compromise: A Case Report.

Upper airway compromise is a potentially life-threatening condition requiring a high index of suspicion and proper and timely treatment planning. The present case describes a 40-year-old man presenting with upper airway obstruction secondary to inconspicuous retropharyngeal subcutaneous emphysema after uncomplicated video-assisted thoracic surgery (VATS).

Recognizing warning signs, management of subcutaneous air with decompressive techniques, and vigilant airway observation and maintenance are crucial to avoiding emergent airway obstruction and poor outcomes. .
