Anatomical Landmarks in Facial Surgery and Trauma

Significance of Anatomical Triangles in Facial Trauma

  • Midface trauma assessment often presents with severe edema, periorbital ecchymosis, enophthalmos, facial asymmetry, and malocclusion, according to the American College of Radiology 1
  • Zygoma fractures are the second most common isolated facial fracture, as reported by the American College of Radiology 2
  • Zygoma fractures are the second most common isolated facial fracture, and understanding facial anatomy is crucial when evaluating midface injuries, according to the American College of Radiology 3

Clinical Implications

  • The American College of Radiology recommends CT maxillofacial as the preferred initial imaging modality for suspected midface injuries, as it provides high-resolution delineation of osseous and soft-tissue structures 1
