Zygoma Arch Fracture Reconstruction, 3rd Try or Not? Would Leaving It As is Cause Future Problems? (photo)

I had 2 operations to repair zygoma arch fracture among other fractures. 1st, the docs pushed the fracture from the cut made in the mouth which did not stick. 2nd, they made a small cut in the cheek to pull the fracture out, which again did not stick. They now say they'd rather leave it as is as the next operation may cause major problems for facial nerves--the only way to repair is to fix a metal plate with screws, which would require a very large cut in the head almost down to front of the ear.
