Chin Trauma and Condylar Fracture

While major jaw fractures are usually present in conjunction with other severe injuries, a less significant blow, such as an impact to the chin from a bicycle or trampoline fall, can result in a fracture of the mandibular condyles and/or posterior teeth.

Symptoms and Findings

  • Preauricular swelling
  • Pain
  • Limited ability to open mouth
  • Deviation on mouth opening
  • Palpable movement of condylar heads
  • Altered occlusion
  • Posterior tooth fracture (not always visualized)


  • Refer to oral surgeon emergently
  • Fractured posterior teeth should prompt concern for condyle fracture and cervical spine injury
