Mastopexy is generally regarded as having only a temporary effect. To prevent recurrent ptosis, mesh has been inserted successfully and safely, without oncological drawbacks, for almost three decades. Recently, preshaped three-dimensional knitted polyester mesh in different sizes was introduced to reinforce the breast during mastopexy. Until now, however, the physical and mechanical characteristics of mesh inserted in the female breast were unknown.
Polyester mesh removed from breasts in which it had been implanted was subjected to mechanical tests (two implants) and histological examination (five pieces of implant).
Mesh induces only a thin layer of collagenous tissue together acting as a composite material. The collagen increases the in-plane stiffness of the mesh and enhances the overall strength. The composite is so strong that rupture or failure is extremely unlikely. The mesh composite shows high pliability, is therefore very supple and not palpable under the skin.
Three-dimensional knitted polyester mesh appears to possess the proper mechanical characteristics to reinforce a ptotic breast during mastopexy.
乳房固定术通常被认为只有暂时的效果。为防止复发性乳房下垂，近三十年来，已成功且安全地植入网片，且不存在肿瘤学方面的弊端。最近，引入了不同尺寸的预成型三维针织聚酯网片，用于在乳房固定术中加固乳房。然而，迄今为止，植入女性乳房的网片的物理和机械特性尚不清楚。
对从已植入网片的乳房中取出的聚酯网片进行力学测试（两个植入物）和组织学检查（五片植入物）。
网片仅诱导形成一层薄薄的胶原组织，共同作为一种复合材料起作用。胶原蛋白增加了网片的面内刚度并增强了整体强度。这种复合材料非常坚固，极不可能破裂或失效。网片复合材料具有很高的柔韧性，因此非常柔软，在皮下不可触及。
三维针织聚酯网片似乎具有适当的机械特性，可在乳房固定术中加固下垂的乳房。
