Bone
Zygomatic bone
Cheek prominence and outer orbital support
High-yield
The zygomatic complex supports both cheek contour and the orbit. The arch lies lateral to the coronoid process and the temporalis tendon.
Overview
The zygomatic bone forms the prominence of the cheek and part of the orbital rim, lateral wall and floor. Its temporal process joins the temporal bone’s zygomatic process to complete the zygomatic arch.
Reference facts
- Bone type
- Irregular facial bone
- Key landmarks
- Frontal and temporal processes, orbital surface, and zygomaticofacial foramen
- Articulations
- Frontal bone, maxilla, temporal bone and greater wing of the sphenoid
Clinical correlation
A displaced zygomatic injury can flatten the cheek. An inwardly displaced arch may obstruct coronoid movement and restrict mouth opening; the effect depends on the fracture pattern and displacement.
