What is the best treatment for dog ear incision after mole removal? (photos)

I would agree with your plastic surgeon that extending the scar to remove the dog ears after your mole removal would be the best method of repair.  

Thank you for your question.  If you have not seen any further improvements in the appearance of your scar to this point I would recommend excising the dog ears and placing the scar within the laugh line of your cheek.  This will lead to a good cosmetic result and will correct the contour irregularities.  Three months will also be enough time for the incision to heal sufficiently that any redness should be easily concealed by makeup.  

Thanks for the question. At 6 months, I don't think that significant additional flattening of the scar ends will occur, especially on young skin. I agree that these dog ears should be excised and the scar slightly lengthened for a more natural contour. Combing surgery with laser resurfacing intraoperatively can give a superior cosmetic result.
