Anatomy The zygoma is the most anterolateral projection of the midface. It plays a key role structurally as it absorbs and dissipates forces away from the cranial base. The zygoma also comprises a significant portion of the inferior and lateral orbital walls; thus, fracture of the zygoma warrant investigation into fractures of the orbit. The zygoma has four articulations, referred to as the ZMC complex: 1. Zygomaticotemporal (ZT) suture - The temporal process of the zygoma articulates with the zygomatic process of the temporal bone to form the anterolaterally projected zygomatic arch (ZA) 2. Zygomaticomaxillary (ZM) suture and the infraorbital rim (IOR) 3. Zygomaticofrontal (ZF) suture 4. Zygomaticosphenoidal (ZS) suture NOTE: Fractures of the ZMC complex may be mistakenly referred to as "tripod fractured," though the correct terminology is, in fact, "tetrapod fracture," given the four articulations of the zygoma as stated above.
