This surgery is also a type of regional subcutaneous fascia lift. Its two main goals are as follows: preventing and improving the skin conditions after mandible reduction, such as lower cheek and jawline drooping or laxity, and simultaneously performing upper neck lift to ensure that the reconstructed face is almost perfect as oval or “V” shape. During the procedure, Dr. Chuang will make a 3–4-cm “S”-shaped incision from the front to the back of the earlobes first; he will then detach the skin and superficial fascia along the jawline from the incision forward to the mouth corners, excise partial preauricular fascia, lift it backward to the back of the ears, and tightly fix the fascia on the periosteum with lift sutures. After checking the tension of skin flap, some extra and loose skin should be removed and wound is closed. If patients have severe or obvious skin laxity, Dr. Chuang can also perform lower face MACS lift or utilize Endotine Ribbon implants to obtain a much better tightening result than ordinary lifting threads. Because the surgical range is limited in the subcutaneous layer that keeps an obvious distance away from the subperiosteal spaces for mandible reduction, these two procedures would not interfere with each other. Therefore, this procedure can be performed with mandible reduction at the same time or nay be combined with lower face or chin liposuction to enhance the result of face slimming. The result of this surgery will last for 3–5 years.
