Following radical tumor resections or severe trauma, particularly in the head and neck region, cartilage or bone grafts serve as frame work in defect reconstruction. As an alternative, porous plastic material was used for preformed free flaps in an experimental study with 28 New Zealand rabbits. Due to ingrowth of fibrous tissue and capillaries, it was possible to obtain prefabricated flaps consisting of vascularized porous plastic, a thin layer of fatty gliding tissue and full thickness skin graft. The blood supply of all three layers of the transplant was confirmed by microangiography, Tc 99 m labeled red blood cells and histological examination.
在根治性肿瘤切除或严重创伤后，特别是在头颈部区域，软骨或骨移植可作为缺损重建的框架。作为一种替代方法，在一项对28只新西兰兔进行的实验研究中，多孔塑料材料被用于预制游离皮瓣。由于纤维组织和毛细血管的长入，有可能获得由血管化多孔塑料、一层薄的脂肪滑动组织和全厚皮片组成的预制皮瓣。通过微血管造影、Tc 99 m标记红细胞和组织学检查证实了移植物所有三层的血液供应。
