What it is
The cheekbone: a four-sided body forming the prominence of the cheek, with a frontal process up the lateral orbital rim and a temporal process joining the temporal bone to complete the zygomatic arch.
Function
Shapes the cheek, forms the lateral wall and floor of the orbit and anchors the masseter.
Size
≈ 5 cm wide, 4 cm tall
Clinical note
A "tripod" fracture separates it at its three sutures after a blow to the cheek.
