Traditional facial thread lifting has nearly inevitable side effects e.g. facial edema, facial bruising, prolonged recovery, skin puckering, and visible and/or palpable threads, as well as less common complications e.g. damage of facial vital structures. Applying the extrafacial loose areolar (XFLA) thread lifting technique by using loose areolar connective tissue, the fourth layer of the scalp, as insertion medium for the threads to be anchored to the layer above (epicranial aponeurosis or galea aponeurotica) and the layer below (pericranium), could help minimize most of the previously mentioned side effects. In this manuscript, technique steps will be detailed to prove its novelty.展开更多

The buttress thread （ based on API standard） is used and foreign experience in connector design is referred to. With this kind of connector, the lifting pipe wiU only bear the axial force, free of moment. The strength of the connector is analyzed in detail, including the connecting strength of the buttress thread, the dynamic load of the pipe system, pressures inside and outside of the pipe, the lateral stress of the pipe wall and so on. Especially, a geometric model is built for 3-D contact stress analysis. The distribution graph of contact stress is presented. It is indicated that the strength of the spherical connector meets the demand.展开更多
