Frontal Process of Zygomatic Bone

Description

The frontal process is the thick, superior projection found on the upper aspect of the zygomatic bone. The frontal process:

—consists of the orbital tubercle and the anteroinferior portion of the temporal fossa;

—provides attachment sites for the lateral palpebral ligament and temporal fascia;

—contributes to the formation of the lateral wall of the orbit;

—articulates superiorly with the zygomatic process of frontal bone, forming the frontozygomatic suture;

—articulates posteromedially with the zygomatic margin of the greater wing of sphenoid bone, forming the sphenozygomatic suture.
