Can I have my Medpor cheek implants removed by a different surgeon? Will it be easy to remove?

I had medpor cheek implants placed an over a year ago. They are the smallest size available so they aren’t large. However my face looks very big and I want them removed. Would it be easy for another surgeon to removed the implants, and will there be sagging? And if sagging is a possibility is there anything that can be done to lift the area during removal ? These are medpor implants with screws will removal be complicated? I hope not
