ABSTRACT

The zygoma is comprised of two main components: the body, which creates the cheek prominence, and the arch, which articulates with the zygomatic process o f the temporal bone. Three-dimensionally, the zygoma has a lateral (malar) surface and a medial (orbital) surface. From the standpoint of the orbit, the zygoma comprises the lateral orbital wall. The masseter muscle and fascia attach to the inferior border of the arch. During a fracture, this muscle produces a downward force on the zygoma. The temporal fascia attaches to the superior border of the arch.
