zygomatic arch
Pronunciation: zy-go-MAT-ik
Bony prominence of the cheek formed by the temporal and zygomatic bones, commonly fractured in facial trauma.
Full Definition
A curved bony structure that forms the prominence of the cheek, created by the articulation of the zygomatic bone and the temporal bone. The zygomatic arch provides structural support for facial muscles and helps define facial width and contour. It is frequently involved in facial trauma and may require surgical reduction and fixation when fractured, particularly in cases affecting facial symmetry or temporomandibular joint function.
