Chin implant asymmetrical swelling. is it because one side was injured during the first procedure?

I had a revision chin implant procedure done on Wednesday. The original implant was malpositioned, the right wing was protruding through my gum line. During revision my PS replaced the implant and fixated with screws. So now my right side is a bit more swollen and numb that the left. I am concerned that its is due that the new implant could shifted again, although unlikely given that it was fixated with multiple screws. Or is it because my right side was more injured during the first procedure?
