Under the operation of a professional liposuction doctor, the incision of the liposuction part of the back is usually selected in a hidden place, and the suction tube used in liposuction surgery can be flexibly selected according to the different liposuction parts. The thinner straw generally needs no suture, and the thicker straw needs a small incision, but only one needle is needed. The incision design is hidden, and the postoperative incision scar is extremely inconspicuous. Therefore, we must be careful when choosing doctors and hospitals.
