Evaluation
- Exam
- Flattening of malar eminence
- Eye findings
- Eye may appear to tilt (pulling of lateral canthus)
- Subconjunctival hemorrhage
- Trismus (masseter spasm or impingement of temporalis muscle or coronoid process)
- Palpate posterior surface of arch for tenderness/loss of space compared to other side
