5.4' tall,38 yr old women. did the BA surgery but the implant never drop down on left side . my surgeon suggested to re-do only the left side by cutting the lower pole ( keep the existing implant) and bring down the implant, 1:) Will it have high chance that the current implant gets contaminated? 2:) may i ask if the scar will move up after the implant drown down? 3:) implant is smooth round one, will the revision surgery cause even higher risk for malposition in future?
