Fractured Zygomatic Arch Needs Repairing, Again. Are There Any Permanent Solutions? (photo)

I fractured my left zygomatic arch, 5mm indent. I had it fixed w/ surgery 30 days later (!!!) without plates, but he warned it may not stick. Anyway 2 months later it's now collapsed (not as badly) and I have major pressure headaches, pain when I eat, and ear pain. I can't even sleep well unless I take something. Aesthetically I would like it fixed too, I feel self conscious and "flat" on one side and I hate being looked at, which is a big deal for an aspiring actress! It can be fixed right?
