What does zygoma mean?
A zygoma is the zygomatic bone, the cheekbone that forms the visible prominence of the cheek and contributes to the structure of the face. Anatomists may also use the term for the zygomatic arch, the bridge-like bony structure connecting the cheekbone region with the temporal bone of the skull. The word is most often encountered in medical and anatomical contexts, including descriptions of facial fractures, reconstructive surgery, and skull anatomy. Because “cheekbone” is its everyday equivalent, zygoma can feel especially useful when precision matters, such as distinguishing a particular bone or arch from the cheek as a whole. Its etymology reflects the Greek word zygon, meaning “yoke,” an image connected with the way the bone helps support and link parts of the skull.
nounThe zygoma, or zygomatic bone, is the bone forming the prominence of the cheek. In extended anatomical use, it may also refer to the zygomatic arch, the bridge-like structure formed by the zygomatic bone and the temporal bone.
- The zygomatic bone forming the prominence of the cheek.
- The zygomatic arch, formed by the zygomatic bone and the temporal bone.
"The fracture involved the zygoma and required careful monitoring to protect the structures of the cheek."
"Her zygoma was prominent beneath the skin."
"The radiograph showed a fracture of the zygomatic arch."
The plural zygomas is standard in general English; zygomata is also used in anatomical contexts.
"The scan showed fractures affecting both zygomas."
The zygoma gives the cheek its prominence, and its name comes from the Greek word for “yoke”—an apt metaphor for a bone that helps link the cheek to the skull.

Etymology of zygoma
The English word entered medical usage in the early 17th century from New Latin zygoma. This Latinized form comes from Greek zygōma, meaning “yoke,” which in turn derives from zygon, “yoke.” The root is shared with related terms such as zygomatic, zygote, zygous, and zygodactyl.

How zygoma is actually used
This is primarily formal anatomical terminology, especially in medicine, dentistry, and descriptive anatomy. “Zygoma” alone is often used when the zygomatic bone is clearly intended.
Easily confused with zygoma
A zygoma is the anatomical bone itself, while zygomatic is the adjective describing that bone and the muscles or regions associated with it.
