The zygoma, or cheekbone, is a paired bone located on the lateral side of the face. Its primary function is to provide structural support to the midface. It helps to form the prominence of the cheek, the lateral wall and floor of the orbit (eye socket), and part of the temporal fossa (a depression on the side of the skull).
The zygoma also plays a role in:
- Protecting the eye: It contributes to the bony framework surrounding the eye, offering some protection from injury.
- Anchoring facial muscles: Several muscles involved in chewing, facial expressions, and moving the jaw are attached to the zygoma.
- Providing attachment for ligaments: Ligaments connect the zygoma to other bones in the skull, helping to stabilize the facial structure.
Due to its prominent position, the zygoma is susceptible to fractures, often resulting from facial trauma.
