Zygomaticomaxillary Complex (ZMC)
In the past the ZMC was frequently referred to as a tripod but functionally it is more correct to consider it as having four legs, like a four-legged stool. This analogy helps to understand the likely sites of fracture and displacement when the ZMC is struck by a direct blow.
Below are the anatomical structures corresponding to the four legs of the stool?
Lateral orbital rim
Inferior orbital rim
Zygomaticomaxillary buttress – the thickened area of bone forming the lateral wall of the maxillary sinus
Zygomatic arch
