Lifting Techniques

Abstract Embedding thread lift rhytidectomy, also known as “thread lifting” in China, with the natures of simple operation, less trauma and quick recovery, is progressively used in clinical practice as a new technology of face lifting. Herewith, a brief introduction of the previous advances of thread lifting techniques and materials in the facial beauty industry, combined with the discussion on various types of sutures, common complications, and the site of actions were provided. The main limitations of present thread lifting material include: (1) the use of non-absorbable sutures is liable to cause allergies and a series of complications; (2) the absorbable sutures are easily degradation, and people need to reshape in a relatively short period. Therefore, the high biocompatible spider silk was proposed as a novel material of thread lifting suture and related devices, the advantages and preliminary achievements on spider silk were also addressed.

AbstractThe problem of finding generators of the subalgebra of invariants under the action of a group of automorphisms of a finite-dimensional Lie algebra on its universal enveloping algebra is reduced to finding homogeneous generators of the same group acting on the symmetric tensor algebra of the Lie algebra. This process is applied to prove a constructive Hilbert–Nagata Theorem (including degree bounds) for the algebra of invariants in a Lie nilpotent relatively free associative algebra endowed with an action induced by a representation of a reductive group.

Probably because the thrust of the pathology of the aging face has been attributed to the effects of gravity (skin and muscle loosening and falling), treatment of such is generally directed toward lifting procedures. Indeed, results from such procedures are generally beneficial, but in many cases the patient appears unnaturally skeletonized. A brow-lift may eliminate some wrinkles and frown lines, but does anyone (naturally youthful) really have eyebrows a centimeter above the orbital rim? Our goal has been, and continues to be, to strive for excellence, and in the case of the aging face, this would be an improved and more youthful appearance. This paper will discuss the main pathology of the appearance of aging, which is the general dissipation of facial fat over time. It will also provide discussion as to thoughtful correction of the problem not only with lifting techniques but also with consideration to filling procedures. The judicial use of fat-grafting and various synthetic implants serve as the principal tools for volume correction. It is acknowledged that the skin undergoes photo-damage, which also contributes to the appearance of aging, but this is treated by treating the skin in a multitude of ways.
