| pubmed-article:7924609 | pubmed:abstractText | The aim of prefabricated free transplants is to create a composite graft including a vascular pedicle with artery and vein, a muscle and its nerve, cellular tissue, bony tissue, cartilage, periosteum, and skin with its sensory nerve. This composite transplant is entirely constructed and modelled around the chosen vascular pedicle beforehand. Once the various materials of the future graft are removed and put in contact with the vascular pedicle, the subsequent neovascularisation should nourish the different elements. The vasculonervous pedicle, with the graft, are transplanted five weeks after preconstruction, revascularized and reinnervated. With these free prefabricated transplants, graft tissue which does not exist in the organism can be created. Cosmetic sequellae can be avoided since the vascular pedicle is chosen beforehand. Ear-nose-throat and plastic surgeons have used local structural preconstruction for many years, especially for ear reconstruction. The work presented here has the original feature of revascularized free transplant. From 1988, we have performed two complete reconstructions of the nose using a free forearm transplant modelled into a nasal pyramid. The classical techniques could not be used. In the first case a radius strut was used to form the nasal crest. In the second a chondrocostal cartilage was used. Transplantation was performed five weeks after preconstruction. In both cases, transplant viability was excellent but the cosmetic and functional results were less than satisfactory and required reoperation. | lld:pubmed |
