The fracture extends diagonally from the pterygoid plates through the maxilla to the inferior orbital rim and up the medial wall of the orbit to the nose. To prevent reherniation an implant is used to. When surgery is performed the herniated displaced orbital tissues are freed and repositioned into the orbit.

The medial and inferior orbital walls are commonly involved in blowout fractures and occur due to high pressures secondary to globe compression.
