I had a deep plane face and neck lift with chin implant last august. I look fine with a straight face but when I smile my chin is rounder now and I lost my pointed chin, my face looks fatter due to the rounded look. Am I good candidate to have it removed or has it been too long? Also is there a possibility of having the implant made smaller to keep the protrusion and remove the rounded part? Also, would removal bring back my jowls?
