학습 자료 둘러보기 →Sudden, severe subcutaneous emphysema around the neck and chest is a critical emergency after total laryngectomy. It indicates air is escaping from the airway into soft tissues, often due to pharyngeal suture line disruption or tracheal injury.
This air dissects along fascial planes and can rapidly cause airway compression, pneumomediastinum, or tension pneumothorax. Immediate recognition and reporting to the surgical team is vital.
Do not confuse this with expected findings. A small amount of localized air or blood-tinged mucus is common. The key differentiator is sudden onset and severe, spreading distribution.
