It all depends on the position of the nipple/areolar complex position. If there is significant loose skin, then the vertical incision is necessary to give you the ideal result. The length of the vertical scar is not long, only 4-5 cm from the bottom of the areola to the crease. This scar heals very well. If there is a lot of excess skin, then the anchor incision is necessary.
You may notice an improved body contour immediately (for instance, if you have your saddlebags suctioned), but your results will be disguised initially by swelling. Swelling should improve dramatically after six weeks and continue to go down over the next six months. If you think you’ll need more lipo to get the result you want, wait at least six months for the swelling to subside, then evaluate the situation with your surgeon. Just keep in mind that you’ll continue healing and seeing better results for up to a year.
