McGrigor-Campbell lines

McGrigor-Campbell lines are imaginary lines traced across the face on an occipitomental (Waters) view skull radiograph to assess for fractures:

  • first line is traced from one zygomaticofrontal suture to another, across the superior edge of the orbits
  • second line traces the zygomatic arch, crosses the zygomatic bone, and traces across the inferior orbital margins to the contralateral zygomatic arch
  • third line connects the condyle and coronoid process of the mandible and the maxillary antra on both sides
  • fourth line crosses the mandibular ramus and the occlusal plane of the teeth

The face is inspected for any asymmetry along these lines and Dolan's lines.
