Which is not true of Ludwig’s angina?
**Core Concept**
Ludwig's angina is a severe, life-threatening infection of the submandibular space, characterized by rapid progression and potential airway compromise. It is typically caused by polymicrobial flora, including anaerobic bacteria, and often presents with severe swelling, pain, and difficulty swallowing.
**Why the Correct Answer is Right**
The correct answer is related to the pathophysiology of Ludwig's angina. Ludwig's angina is a space-occupying lesion that can cause rapid swelling and airway compromise, but it is not typically associated with trismus (lockjaw) or decreased jaw mobility. The infection usually causes significant pain and swelling, but it does not usually involve the temporomandibular joint or the muscles of mastication, which are responsible for jaw movement.
**Why Each Wrong Option is Incorrect**
**Option A:** Ludwig's angina is often associated with severe pain and swelling, but it can also present with difficulty swallowing (dysphagia) and airway compromise, making this option incorrect.
**Option B:** Ludwig's angina is a polymicrobial infection, often involving anaerobic bacteria, which can cause severe tissue damage and swelling, making this option incorrect.
**Option C:** Ludwig's angina is a space-occupying lesion that can cause rapid swelling and airway compromise, making this option incorrect.
**Clinical Pearl / High-Yield Fact**
Ludwig's angina is a medical emergency that requires prompt recognition and treatment, often involving airway management, broad-spectrum antibiotics, and surgical drainage of the infected space.
**Correct Answer: C. Ludwig's angina is not typically associated with trismus (lockjaw) or decreased jaw mobility.**
