Definition Of zygoma

noun

the bony arch of the cheek formed by connection of the zygomatic and temporal bones.

Using the endoscope through the small lateral incision, the surgeon dissects the entire cheek from the orbital run over to the nose, down to the top of the mouth out to the side over the zygoma so the whole cheek can be freed and moved up.
