Malar implant (medpor) infected, now what? (Photo)

About one year ago I had Malar surgery because I have always had flat cheeks. I had 2 medpor implants size small and one got infected and I had to do a surgery to take it out. Now I want to put another implant to be symmetrical but I don't want another infection to happen. What could I tell my surgeon to do to avoid it? Maybe screw the implant? Because in the past he did not screw. Anything I could ask him? Secondly, I think that small size was too small for me and I would like medium.
