Although extensive research regarding the treatment of calvarial defects has been done in adult models, little is known about the response in the maturing skeleton. The role of coralline hydroxyapatite and expanded polytetrafluoroethylene membrane in augmenting bone growth and repair of calvarial defects in a neonatal model is explored. Utilizing a(More)
Cartilage is often used as structural support tissue for cosmetic repair in plastic and reconstructive surgery. We describe the efficacy of a new approach for the generation of cartilage in predetermined shapes using specially configured biodegradable synthetic polymer devices as delivery vehicles for transplanted cells. Synthetic biodegradable polymer(More)
The authors tested the feasibility of using tissue-engineered cartilage, grown in the shape of cylinders, for replacing large circumferential defects of the cervical trachea in rats. Chondrocytes obtained from the shoulder of newborn calves were seeded onto a synthetic nonwoven mesh, 100 microns thick, of polyglycolic acid fibers 15 microns in diameter, cut(More)
Injection of polytetrafluoroethylene (Teflon) or collagen has been used in the endoscopic treatment of vesicoureteral reflux. Although the principle of an endoscopic treatment is valid, there are concerns regarding the long-term safety and effectiveness of these substances. The goal of several investigators has been to find alternate implant materials that(More)
We tested the efficacy of a new approach for the tissue-engineered growth of cartilage developed in our laboratory in repairing surgically created bone defects in the craniums of rats. Large cranial defects were created bilaterally in the frontoparietotemporal bones of athymic nude rats (n = 10). There was gross evidence of new cartilage in 8 of 10(More)
Injection of polytetrafluoroethylene (Teflon) or collagen has been used in the endoscopic treatment of vesicoureteral reflux. Although the principle of an endoscopic treatment is valid, there are concerns regarding the long-term safety and effectiveness of these substances. In search of a different injectable material we conducted experiments using(More)
Current treatment modalities for soft tissue augmentation which use autologous grafting and commercially available fillers present a number of challenges and limitations, such as donor site morbidity and volume loss over time. Adipose tissue engineering technology may provide an attractive alternative. This study investigated the feasibility of a degradable(More)
PURPOSE Capsular contracture is the most troublesome complication after aesthetic breast surgery. Capsule formation can be seen as a normal foreign body reaction caused by implant insertion into the body. Pathological capsular contracture can lead to severe symptoms including pain, tenderness, and breast distortion. Hypertrophic scar hypothesis, one of the(More)
Diced cartilage grafting has re-emerged as a popular method in aesthetic rhinoplasty since the introduction of Erol's Turkish delight technique. However, an extensive literature review indicates that diced cartilage grafts with Surgicel(®) wrapping are usually absorbed and often fail to correct associated clinical problems. Recent studies show that(More)
