A child has a unilateral condylar fracture. On opening, in which direction is the condylar fragment displaced?
Show answer and explanation
Correct answer: A. Medial
- A. CORRECT. The lateral pterygoid pulls the fractured condylar fragment anteromedially, so it displaces medially, and the mandible deviates toward the affected side on opening.
- B. INCORRECT. Lateral displacement is not the typical pattern of pull by the lateral pterygoid.
