List three red-flag symptoms in TMD that require urgent evaluation.

• A. Severe facial swelling with fever, inability to open mouth with mandibular movement, trauma history with malocclusion.
• B. Mild facial swelling with fever.
• C. Trauma history with malocclusion.
• D. Ear fullness.

Answer: (D)

The key idea is recognizing red flags in TMD that signal urgent problems such as infection, fracture, or dislocation that need prompt evaluation. Severe facial swelling with fever points to an infectious or inflammatory process in the facial spaces near the jaw, which can progress rapidly and threaten the airway or spread if not treated quickly. Inability to open the mouth with mandibular movement, i.e., marked trismus, suggests acute TMJ pathology such as a dislocation, condylar fracture, septic arthritis, or an adjacent space infection—situations that require immediate assessment. A trauma history with malocclusion indicates possible acute condylar fracture or TMJ dislocation or significant dental trauma altering the bite, all of which are urgent concerns. Together, these three signs form a triad that flags urgent evaluation.

The other options don’t present that same urgent triad. Ear fullness is a common, nonspecific symptom that can be seen with benign TMJ or ENT issues and doesn’t by itself indicate an emergent process. Mild facial swelling with fever is less alarming than severe swelling with fever, and trauma history with malocclusion alone may raise concern but isn’t as strong an indicator of an acute, high-risk condition as the combination described above.
