The zygomatic arch is a bony structure on the side of the skull that forms the cheekbone. It is made up of two bones: the zygomatic bone and the temporal bone. This arch provides support for the face and serves as an attachment point for muscles involved in chewing. In addition to its structural role, the zygomatic arch helps protect the orbital cavity, which houses the eyes. It also contributes to the overall shape of the face, influencing facial aesthetics and symmetry. Injuries to the zygomatic arch can affect both appearance and function.
