OBJECTIVE To evaluate the effect of bone marrow-derived mesenchymal stem cells (BM-MSCs) transplantation on tissue expansion. BACKGROUND Tissue expansion provides a better solution to large defect reconstruction with perfectly matched skin and without deformity at the donor site. How to promote tissue expansion and reduce complications has been a focus in(More)
BACKGROUND It is still highly challenging to restore the esthetic neck contour for postburn deformities. In many patients with burns, the back skin remains intact, which is a useful donor site for extensive contracture release. As the main technique, the refinement of the pre-expanded superficial cervical artery (SCA) flaps may improve its application in(More)
BACKGROUND Resurfacing of facial massive soft tissue defect is a formidable challenge because of the unique character of the region and the limitation of well-matched donor site. In this report, we introduce a technique for using the prefabricated cervicothoracic skin flap for facial resurfacing, in an attempt to meet the principle of flap selection in face(More)
Flap prefabrication is started with transposition of a vascular pedicle into a donor area that lacks an axial blood supply. Adipose-derived stem cells (ASCs) have been proven beneficial for promoting neovascularization and tissue regeneration in several animal models. Here we investigated the feasibility of applying ASCs as a novel strategy to promote flap(More)
BACKGROUND Supraclavicular flaps had been widely used as pedicled flaps to reconstruct face and neck defects. However, the size of this traditional flap was limited even after expansion. In this study, we present a flap pedicled by the thoracic branch of supraclavicular artery (TBSA). The flap is located at the subclavicular region, and has the advantage of(More)
BACKGROUND For large defects or deformities of the face and neck, the anterior chest area appears to be an excellent donor site that provides well-matched skin colour and texture. Many flap techniques based on the anterior chest area have been reported; however, there are few reports that focus on a treatment strategy for these different flap techniques. (More)
Different XML formats are widely used for data exchange and processing, being often necessary to mutually convert between them. Standard XML transformation languages, like XSLT or XQuery, are unsatisfactory for this purpose since they require writing a separate transformation for each direction. Existing bidirectional transformation languages mean to cover(More)
Putback-based bidirectional programming allows the programmer to write only one putback transformation, from which the unique corresponding forward transformation is derived for free. The logic of a putback transformation is more sophisticated than that of a forward transformation and does not always give rise to well-behaved bidirectional programs; this(More)
OBJECTIVE To introduce a new prefabricated flap with matched colour, texture, thin enough thickness, large enough dimension and reliability for reconstruction of massive defect of face and neck. METHODS The patients with massive scar of face and neck were selected for treatment with prefabricated flap. Flap prefabrication involved two stages. The(More)
BACKGROUND The face is one of the most important regions of the human body and contains complicated and delicate features that define the identity of a person. Treatment for extensive facial deformities requires resurfacing of the extensive skin defects and restoring the missing features. To date, it remains a major challenge to the reconstructive surgeons.(More)
