The effectiveness of stem cell therapies has been hampered by cell death and limited control over fate. These problems can be partially circumvented by using macroporous biomaterials that improve the survival of transplanted stem cells and provide molecular cues to direct cell phenotype. Stem cell behaviour can also be controlled in vitro by manipulating(More)
Repair of skeletal defects with vascularized bone grafts has many advantages over non-vascularized free grafts, but the availability of these grafts is extremely limited. This study was designed to determine whether new vascularized bone could be engineered by transplantation of osteoblasts around existing vascular pedicles using biodegradable, synthetic(More)
BACKGROUND A blow-out fracture is one of the most common facial injuries in midface trauma. Orbital wall reconstruction is extremely important because it can cause various functional and aesthetic sequelae. Although many materials are available, there are no uniformly accepted guidelines regarding material selection for orbital wall reconstruction. (More)
BACKGROUND Partial or complete necrosis of a skin flap is a common problem. Polydeoxyribonucleotide (PDRN) can be extracted from trout sperm and used as a tissue repair agent. The aim of this study was to investigate whether PDRN could improve the survival of random pattern skin flaps in rats. METHODS Twenty-two male Sprague-Dawley rats were randomly(More)
BACKGROUND Conservative techniques designed to block or delay the aging process have been utilized in various ways for many years. However, their effects can be relatively minimal and short-term in most cases compared to surgery. The objective of this study was to evaluate the efficacy and safety of gold thread implantation for the treatment of periorbital(More)
BACKGROUND Orbital roof fractures are frequently associated with a high energy impact to the craniofacial region, and displaced orbital roof fractures can cause ophthalmic and neurologic complications and occasionally require open surgical intervention. The purpose of this article was to investigate the clinical features and treatment outcomes of orbital(More)
concepts of the diagnosis and treatment of necrotizing fasciitis. breast: a rare primary case with conservation of the nipple and literature review. which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. Recently, robotic surgical operations have been performed in many(More)
BACKGROUND Hypertrophic scarring is a pathological condition that occurs after trauma or surgery. Angiogenesis occurs more often with hypertrophic scarring than with normotrophic scarring. The regulation of angiogenesis is one of the key factors in hypertrophic scar management. Vascular endothelial growth factor (VEGF) is an essential factor in the(More)
BACKGROUND Capsular contracture is the most troublesome complication in breast implant surgery. Although capsule formation can be seen as a normal reaction to a foreign body, it can induce pain, hardness, deformity, and other pathologic problems. Surgical intervention is required in severe cases, but even surgery cannot guarantee a successful outcome(More)
