Treatment of Right Zygomaticomaxillary Complex Fracture

Initial Assessment and Imaging

  • CT maxillofacial without contrast is the essential diagnostic modality for evaluating ZMC fractures, providing high-resolution imaging of osseous structures, multiplanar reconstructions, and 3-D reformations critical for surgical planning, as recommended by the American College of Radiology 1, 2
  • This imaging is superior to plain radiography, which misses approximately 12% of maxillofacial fractures, according to the American College of Radiology 3

Key Diagnostic Features on CT

  • Zygomaticosphenoid suture status is a critical indicator of asymmetry and orbital volume changes, as noted by the American College of Radiology 1
  • Degree of displacement and comminution are important factors to evaluate, as recommended by the American College of Radiology 1
  • Infraorbital nerve involvement is a key consideration, according to the American College of Radiology 1

Associated Injuries to Evaluate

  • Cervical spine injury occurs in 6-19% of significant maxillofacial trauma cases, as reported by the American College of Radiology 3
  • Intracranial injury is present in 9% of patients with orbital wall fractures, according to the American College of Radiology 4
  • Blunt cerebrovascular injury (BCVI) screening is not typically required for isolated ZMC fractures, as noted by the American College of Radiology 3
