Facial burns in a burn patient strongly suggest the possibility of an inhalation injury because the face is exposed to smoke, heat, and toxic gases during a fire. Presence of facial burns often correlates with exposure to hot air and smoke that can damage the upper airway and lungs, leading to respiratory complications. Early identification is critical for airway management and preventing respiratory failure. Other features like singed nasal hair, soot in the mouth or sputum, and hoarseness further support this diagnosis. Facial burns should prompt high suspicion and readiness for airway intervention.
