Thanks for your question, and I'm sorry to hear about your injury. The zygomatic arch connects your cheek bone with the bone that contains your hearing apparatus. The muscles of chewing run underneath it. It's an important structure for facial width and symmetry. Zygomatic arch fractures are commonly sustained following a car crash, an assault, or a fall. I'm assuming you had a CT scan of your facial bones. If the bone is not displaced, meaning it is merely cracked but sitting where it should be, it should heal fine without any intervention. You'd need to eat soft foods for the next six weeks while the healing process goes on- your chewing muscles can pull the arch out of place. We reserve repair for situations where the chewing muscles are affected or you'd have a major deformity. Surgery can vary in intensity from merely popping the bone back into place to using titanium plates and screws to move and hold the bones in place while they heal. If there isn't any deformity, you probably will be fine. If you have any subtle asymmetry after the healing finishes, this can be camouflaged with fillers or an implant. Good luck!
