The increased demand for facial rejuvenation treatments has led to many innovations in plastic surgery techniques. Mechanisms of facial aging include loss of skin elasticity, fat atrophy and gravity. Treatments for facial aging include, at a minimum, lifting of sagging soft tissues, autologous fat grafting or prosthetic placement to fill in atrophied and depressed areas, and gravity-fighting face lifts. The trend in plastic and cosmetic surgery is towards minimally invasive, low-risk, quick recovery and easy to perform, which is why sublative cosmetic surgery has gained increasing attention and popularity among doctors and patients in recent years. Embedded wire cosmetic surgery refers to a series of cosmetic surgery techniques by embedding wires in different layers of body surface tissues to achieve aesthetic effects such as lifting and tightening of sagging tissues, filling of depressed tissues, improvement of skin texture, and contour shaping of the body surface. 1, soft tissue lifting The human body in the aging process, the body surface soft tissue will appear volume shrinkage, sagging and other manifestations, the formation of the appearance of aging characteristics. The lifting effect of buried wire cosmetology is mainly realized through the suspension line with serration. By combining the serration of the lower end of the suspension line with the soft tissue, lifting it upward to a satisfactory position and fixing it at the upper end, the lifting effect can be realized. 2, soft combination filler The filler effect of submerged line beauty is mainly realized by smooth line and spiral line, and its principle can have two aspects: one is the physical filler effect of the line itself, and the other is the absorbable line buried, in the process of degradation, it can stimulate the tissue of collagen fibers, elastic fibers, and other connective tissues proliferation, so as to play a filler effect on the small depression. 3, contour shaping In the body surface soft tissue sagging, redundancy caused by unclear contours of the parts, through the suspension line and filler line buried together, can achieve contour shaping effect. 4.Lipolysis In clinical practice, it has been observed that burying absorbable wires in the fat layer can promote the phenomenon of localized fat tissue dissolution and absorption. Utilizing this effect, the filler wire can be buried in the fat accumulation area, which can play the role of lipolysis. 5, skin texture improvement In clinical observation, in the dermis and subcutaneous layer buried filler line, with the passage of time, can gradually appear tightening, brightening effect, which may be related to the degradation process of the wire to stimulate the organization of the collagen fibers, elastic fibers and other connective tissue proliferation and other roles.
