“…Because all the branches converge on the subscapular trunk, transposition on this vessel for pedicled flaps is possible, and free tissue transfer requires only one set of anastomoses for the entire complex. Vascular anomalies have been described that necessitate transfer of several components independently [45,46]. Preoperative angiography can provide elucidation of each patient's individual vascular pattern [47].Chimeric flaps based on the lateral circumflex femoral system also offer great versatility, but for chest wall reconstruction, these flaps always require microvascular transfer [48].…”
Chest wall reconstructions can be complex and challenging procedures and may require a multidisciplinary approach. The most common indications for chest wall reconstruction are the repair of defects due to tumor ablation, infection, radiation necrosis, congenital deformities, and trauma. Flap reconstruction by plastic surgery is often required when skin is removed as part of the chest wall resection or when radiation therapy is given pre- or post-operatively. Tissue flaps may be needed to provide vascularized tissue over alloplastic materials used to stabilize the chest wall, to cover vital structures of the chest cavity, to fill dead space, and to improve cosmesis.

“…If local flaps are not feasible, free tissue transfer often is the treatment of choice because of superior functional and esthetic results. For coverage of defects of the hand, especially the lateral arm flap, the parascapular flap, the anterior lateral thigh flap as well as temporalis and serratus fascial flaps are excellent options [1,6,11,13]. In our practice, the use of the pedicled radial forearm flap is therefore generally limited to Figure 4 Soft tissue defect in a 43-year-old patient exposing a reconstructed extensor tendon in the partially amputated ring finger after loss of the second and fifth digit.…”
Because of the thin skin envelope of the hand, especially at the dorsum, flaps are frequently required for defect reconstruction in the hand. The pedicled radial forearm flap is a time proven procedure that offers reliable coverage in this area without the need of advanced microsurgical expertise. Despite several alternatives and an increasing acceptance of free tissue transfers, the pedicled radial forearm flap can still be the procedure of choice under special circumstances. Variations of the original technique address the two main disadvantages, the conspicuous donor site and the sacrifice of the radial artery. Indications, anatomy, surgical technique, and limitations of this classic workhorse flap are presented.
“…T reatment of extensive soft tissue defects after trauma or cancer therapy is accomplished with flap reconstruction or autologous free-fat grafting [1][2][3][4][5][6]. Both techniques have drawbacks such as donor site morbidity and the unpredictable behavior of fat grafts.…”
Porous PEGT/PBT implants with different physico-chemical characteristics were evaluated to identify its potential as biodegradable and biofunctional soft tissue filler. Implants (50 Â 10 Â 5mm3 ) were implanted subcutaneously in mini-pigs and tissue response, tissue volume generated and its consistency were assessed quantitatively with a 52 weeks follow-up. The absence of wound edema, skin irritation, and chronic inflammation demonstrated biocompatibility of all implants evaluated. The hydrophobic implants induced the mildest foreign body response, generated highest amount of connective tissue and demonstrated a decrease in copolymer MW of 34-37% compared to 90% decrease of the hydrophilic implants. The rate and extent of copolymer fragmentation seems to be the determining factor of success of soft tissue augmentation using porous PEGT/PBT copolymer implants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
