Timing of chin implant removal after revision
If you have definitely decided to remove your chin implant after the revision you had 2 months ago, this could be done at any time. There really is no advantage to waiting any longer to have it removed.
There is no reason to wait. If you do not like it get it removed. Scar will be same, either way. Early removal is preferable.
Chin implant can be removed any time using same incision. You should discuss this issue with your surgeon and follow his instructions. Good luck.
