it is difficult to reconstruct an alar defect with cartilage involvement. here in the authors report a case of traumatic alar loss during childhood in which an alar reconstruction was carried out with a composite auricular graft put over the pedicle buccal flap which was rotated and passed through the intraoral side. the lining skin and auricular cartilage for the flap was obtained from the aur...

conclusions: using these factors, nephrologists may predict the occurrence of graft loss or death. if the probability of graft loss was higher, physicians can decrease the immunosuppressive medications dosage to decrease the incidence of graft loss. patients and methods: fine-gray model was used for 266 cases with post-transplant malignancy in iran. these patients were followed-up from the diag...

BACKGROUND: Dental disease, trauma and maxillofacial surgeries can cause alveolar bone defects. Among different kinds of treatment, autogenous bone grafts is accepted as a golden standard. On the other hand, because of limitation of treatment with autogenous bone grafts, osteogenic cells derived from stem cells are suggested. OBJECTIVES: The aim of this study was to compare the mean density of ...

background: autologous skin graft is frequently used in the field of plastic, and reconstructive surgery. the engraftment is dependent upon revascularization and angiogenesis, which can be regulated by different factors. in addition to its hematopoietic effects, erythropoietin is shown to positively affect the wound healing process. objectives: we studied effects of human erythropoietin on reva...

BACKGROUND Full-thickness skin graft (FTSG) is a very versatile tool regularly used in small sizes. With the established knowledge of the graft take through the margins as well as wound bed, we extended the use of the FTSG for reconstruction of large-sized defects with satisfactory results.  METHODS We presented our experience in wound reconstruction using FTSG in 28 patients. We select...

Cellulose was modified by polystyrene (PS) and polyacrylonitrile (PAN) via free radical and living radical polymerization, and then cellulose was used as the matrix in the preparation of polymer/clay nanocomposite, through a solution intercalation method. For this purpose, first, the graft polymerization of styrene (St) onto cellulose fibers was performed by using suspension polymerization and ...
