  • ageing signals prevention Other important contribution of the Aesthetical/Correction surgeries is the ageing signals prevention. Some individuals tend to acquire more ageing signals than the others and it comprise the enhancing of the face signals such as facial foldings and flaccid skin, in many situations such signals appear before the due time. Therefore, as in the above discussed processes, the degeneration process (natural or not) influence the emotional balance; the self respect of an individual is crucial for the maintenance of the metabolic process, particularly the immunological system at acceptable levels.
  • the physical degradation sensation has a strong effect in the regulation functions of the body metabolism; In many cases one can notice increasing of infectious diseases or others caused by the continous lower of the self respect of an individual when he strongly believes in a quick body degradation and so permits a desease raising.

  • Another aspect related to the referred approaches comprises periodical inspection and the risk of body rejection; furthermore the aesthetic effect is quite dependent of the material quality, i.e., the prosthesis instrument can be misadjusted the local body part and the effect will be not satisfactory.
  • Another embodiment comprise surgical threads for flaccid tissue lifting; such approach is known as surgical thread lifting. The surgical thread is applied under the skin through the fat tissue performing a cohesive lifting effect.
  • One advantageous feature of the above mentioned approach is that it is less invasive than the above mentioned invasive alternatives, reducing the not desired effects previously discussed; the surgical threads - inserted under the sking in the fat tissue - permit a better positioning during the correction surgery providing an enhanced aesthetic effect; the tensile strengh and the lenght of the thread can be defined by the surgeon.
  • Threads of the art have a fragile tensile strengh when they are submitted to mecanical tension, therefore the resulting effect is not satisfactory and another correction procedure will be necessary.
  • Another limiting aspect of the art comprise the fragility of the hooks. Threads of the art have hooks which is inclined in relation to the thread axis and it comprises a fragile point of the structure. The hooks of such known threads commonly collapses in a progressive effect, therefore a loss of tissue lifting feature is verified.

  • the patent document EP1075843 refers to a surgical thread for flaccid tissue lifting in which hooks placed alongside the thread body are sequencially oriented and in an opposed direction in relation to the thread traction sense. A first hook arrangement is placed in a direction while the second arrangement is placed in the opposed direction for avoid displacement of the thread under the skin. Also, is provided a method for manufacturing a thread which is able to be inserted in a single thread direction.
