Oncologic management in the mandibular area leaves important osseous defects, that require reconstructive procedures with vascularized osseous tissues. Mandibular reconstructions with free vascularized fibular flaps have well-defined indications and some advantages over various other types of vascularized osseous grafts, because the fibular graft permits the reconstruction of large mandibular defects. This study demonstrates the usefulness of three-dimensional (3D) tomography as a tool to determine the size of the defect, and with angiotomography, to define the anatomic pattern of the vascular pedicle. Five patients with varying mandibular tumors and osseous defects were evaluated with 3D tomography in the pre- and postoperative periods. Two patients were immediately reconstructed with vascularized fibular flaps. 3D preoperative tomography showed the dimensions of the tumor, the dimensions of the mandibular resection, and the graft vascular pattern. Three patients were secondarily reconstructed, two of them with partial mandibular defects, and one patient with total mandibular reconstruction. In the preoperative period, 3D tomography was used to determine the dimensions of the mandibular defect, as well as the area of the osteotomies. The technology permits an exact knowledge of the dimension of mandibular defects, allowing better planning of reconstructive procedures.  相似文献

Although free vascularized iliac bone graft has been successfully used for the reconstruction of large bone defect with microvascular surgery, there is a serious problem of how to repair in one-stage, those cases having a large bone defect with a very wide skin defect. A free combined anterolateral flap and vascularized iliac bone graft with double vascular pedicles seems to be a most suitable method for cases having both large bone and skin defects. Two case reports are presented in which this flap was used. Based on the authors' cases, the advantages of this flap are its thinness and the extreme wideness of the skin territory. The anatomy of the pedicle vessels is large and long, and the donor scar can be made in an unexposed area. This flap can be considered for use in one-stage reconstructions of both large bone and skin defects in the oral and leg regions.  相似文献

It has been very difficult to accomplish simultaneous reconstruction of a massive defect of the long bone associated with a large skin defect. Yoshimura et al reported a new procedure using a vascularized free fibular transplant with a monitoring flap. This procedure was used in four cases that had resulted in massive bone and skin defects after wide resection of benign and malignant bone tumors occurring in the long bones. Our results using the composite vascularized fibular graft were gratifying.  相似文献

Salvage of the upper extremity following tumor resection may require reconstruction of massive bone defects. This more commonly results from malignant bone tumors, but defects requiring reconstruction also may occur following resection of locally aggressive benign tumors. Examples include osteosarcoma, chondrosarcoma, Ewing sarcoma, giant cell tumor, and certain soft tissue sarcomas invading bone. Obtaining satisfactory results using conventional bone grafting techniques is at best challenging when defects of substantial size are encountered. Free vascularized bone grafting procedures provide the appealing option of transferring living bone based on a vascular pedicle.  相似文献

Our experience with microvascular transfer of fibular grafts and composite osteocutaneous iliac flaps has shown that massive autogenous bone grafting with an intact vascular pedicle decreases the time to bony union and the duration of immobilization required for functional reconstruction of an extremity. The technique has proven reliable (87 per cent success rate) in the reconstruction of bone defects of greater than 6 to 8 cm following tumor resection or defects existing in a fibrotic, avascular bed. More importantly, these techniques have been applied for limb salvage in patients with tumors or with severely traumatized extremities that were not candidates for more traditional methods of bone grafting. In many cases, amputation would have been the only alternative.  相似文献

Twenty-nine patients are reported who underwent free tissue transfer reconstruction of contaminated tibia defects with both soft tissue defects and osteomyelitis. Infection was controlled through the use of a two-stage composite tissue reconstruction. In the first stage, the wounds were closed with the free muscle or skin flap. Bone defects were bridged with vascularized bone grafts within 6 to 12 weeks after soft tissue closure. Twenty patients underwent reconstruction using iliac crest, whereas nine patients were treated with fibular transfer. The follow-up period for 28 patients ranged from 10 months to 6 years until bone union was completed. The bone united smoothly in 22 patients, but union of the other six grafts was delayed and required additional cancellous bone grafting.  相似文献

In recent years pedicled and microvascular free muscle flaps, myocutaneous flaps, and vascularized bone grafts have become well accepted reconstructive techniques in the management of complex defects. The deep circumflex iliac artery-based internal oblique muscle pedicle flap, internal oblique free muscle pedicle flap, internal oblique free muscle flap, and the internal oblique-iliac crest microvascular free flap are the latest additions to the reconstructive surgeons' armamentarium. This report describes the surgical anatomy of the internal oblique muscle and the deep circumflex iliac artery from a practical viewpoint with particular emphasis on the vascular basis of the above mentioned flaps.  相似文献
