Background

  • Must distinguish Zygomatic Arch Fracture from Zygomaticomaxillary (Tripod) Fracture
  • Definition = fracture through:
    • Inferior orbital rim
    • Lateral orbital wall
    • Zygomatic arch

Clinical Features

  • Facial trauma (blunt, medially-directed force)
  • Normally depression of tripod (cheekbone) complex
  • Lower eyelid/cheek pain, swelling, and ecchymosis
  • Diplopia with upward gaze (due to extraocular muscle contusion/entrapment, orbital hematoma)
  • Trismus

Differential Diagnosis

Maxillofacial Trauma

Evaluation

  • CT face
  • Rule-out associated ocular injuries or other trauma

Management

  • Usually requires admission and surgical repair

Disposition

  • Loss of vision or displacement: admit for IV antibiotics and surgery
