LEARNING OBJECTIVES After reading this article, the participant should be able to: 1. Understand the challenges in restoring volume and structural integrity in rhinoplasty. 2. Identify the appropriate uses of various autografts in aesthetic and reconstructive rhinoplasty (septal cartilage, auricular cartilage, costal cartilage, calvarial and nasal bone, and olecranon process of the ulna). 3. Id...

OBJECTIVE Platelet-rich plasma (PRP) has the capacity to improve the bone-healing process. The aim of this pilot study was to investigate the occurrence of bone healing and the time taken to achieve this in patients submitted to medial opening wedge high tibial osteotomy (MOWHTO), comparing platelet-rich plasma with bone marrow aspirate to autologous iliac graft. DESIGN Twenty-five patients w...

Organ restoration via cell therapy and tissue transplantation is limited by impaired graft survival. We tested the hypothesis that ascorbic acid (AA) reduces cell death in myocardial grafts both in vitro and in vivo and introduced a new model of autologous graft vascularization for later transplantation. Luciferase (Fluc)- and green fluorescent protein (GFP)-expressing H9C2 cardiomyoblasts were...

Prosthetic grafts are required for coronary artery bypass grafting (CABG) when the availability of suitable autologous conduits is limited. The ideal cardiovascular bypass graft requires a broad range of characteristics including strength, viscoelasticity, biocompatibility, blood compatibility and biostability. Many alternative conduits have been developed and used in the past, but most of them...

Introduction: The lenticular process of the incus succumbs to necrosis in chronic otitis media. Few researchers have addressed the issue of autograft incus preservation in the soft tissue of the tragus or mastoid cavity. Nonetheless, preservation of the incus in this method during the second stage of ossiculoplasty is a subject that is still up for debate. This study was carried out to demonstr...

OBJECTIVE To evaluate the clinical efficacy and safety of HYAFF 11-based autologous dermal and epidermal grafts in the management of diabetic foot ulcers. RESEARCH DESIGN AND METHODS A total of 79 patients with diabetic dorsal (n = 37) or plantar (n = 42) ulcers were randomized to either the control group with nonadherent paraffin gauze (n = 36) or the treatment group with autologous tissue-e...

Ionescu, M. I., Pakrashi, B. C., lary, D. A. S., Bartek, L. T., and Wooler, G. H. (1974). Thorax, 29, 56-67. Replacement of heart valves with frame-mounted tissue grafts. Between April 1969 and March 1973, 213 patients had heart valve replacement with frame-mounted autologous or homologous fascia lata or with heterologous pericardial grafts. There were 111 single aortic, 95 single mitral, and s...

PURPOSE Various graft materials, such as synthetic and biological products, are used routinely in maxillofacial surgery. These materials are usually derived from porcine, bovine, and human tissues; some religious beliefs forbid the dietary use of substances from certain animal sources. The aim of this study was to evaluate the effect of religious belief on selecting different graft types used i...

Emerging nanotechnologies have enabled the use of magnetic forces to guide the movement of magnetically-labeled cells, drugs, and other therapeutic agents. Endothelial cells labeled with superparamagnetic iron oxide nanoparticles (SPION) have previously been captured on the surface of magnetizable 2205 duplex stainless steel stents in a porcine coronary implantation model. Recently, we have coa...
