The Long-term Results of Purse-string Facelifts（2）
The Procedures
Purse-string sutures are firmly anchored at either the zygomatic arch (S-lift and QuickLift) or at the temporalis fascia (MACS lift). The S-lift and the MACS lift use an O-shaped and a U-shaped purse-string. The MACS lift in some cases uses a third suspension purse-string to elevate the malar fat pad.
The QuickLift features a central, oval-shaped purse-string surrounded by an extremely large encircling purse-string. When purse-string suspension sutures are tightened, the SMAS is compressed, forming multiple gyri which then fibrose and give longevity to the procedure. In addition, as the purse-string is tightened, there is a pulley-type effect that strengthens the suspension with each additional throw of the suture and significantly reduces the chances of SMAS tear-through.
