Although bone grafting has a well-recognised role in orthopaedic surgery for the treatment of nonunion, bridging diaphyseal defects and filling metaphyseal defects, it is associated with postoperative pain and morbidity. When extensive grafting is required, as in spinal arthrodesis and the management of large bony defects, inadequate amounts of autologous bone may not be available. Allograft bo...
introduction: the use of cartilage as a grafting material has been advocated in cases where there is a high risk of graft failure, such as subtotal perforations, adhesive processes, and residual defects after primary tympanoplasties. the purpose of this study was to compare the graft acceptance rates and auditory outcomes of cartilage tympanoplasty operations using a palisade technique with tho...
PURPOSE To evaluate the influence of bone marrow aspirate added to xenograft or alloplast graft matrix scaffold to produce bone. MATERIALS A maximum of 4 cc bone marrow was aspirated from the anterior iliac crest of 5 patients to saturate the matrix scaffold prior to bone graft. Seven graft sites evaluated included sinus lift augmentation, particulate onlay graft of the maxilla via a tunnelin...
Multiple methods and materials are available for bone defect reconstruction. Bone graft substitute is one of the materials used for reconstruction of bone defect and have been widely used recently. This report describes some cases about complications related to GeneX® which is introduced as mixture of calcium sulfate and β-tricalcium phosphate at manufacturer's official web site. It informed of...
Autologous bone grafting remains the gold standard for bone grafting in clinical practice. Although it has withstood the test of time, it remains associated with multiple comorbidities. The search for an alternative bone graft substitute harnessing bone's osteoconductive, osteoinductive, and osteogenic properties remains a challenge. This article examines the various bone grafting materials cur...
Abstract Background Various grafting materials and different techniques have been used for myringoplasty. The aim of the study was to compare result tympanoplasty in patients with safe-type chronic suppurative otitis media using periosteum versus tragal cartilage perichondrium grafts through pre- postoperative clinical audiological evaluation. Results There statistically significant difference ...
Objective- Comprehensive functional, histomorphometrical and immunohistochemical assessment of sciatic nerve regeneration through an inside-out vein graft in rat. Design- Experimental in vivo study. Animals- Fifty- four healthy male White Albino rats. Procedures- The rats were divided into three experimental groups (n=18), randomly: Sham-operation (NC), Transected control (TC) and Inside-out ve...
Background & Aims : The aim of the present study was to compare graft survival and patient survival between diabetic and non-diabetic patients in the Imam Khomeini Hospital Transplant Center, during the years 2001 to 2011. Materials & Methods : This study was a retrospective cohort study. We used Kaplan-Meier test to calculate the patient and graft survival and t-test to compare continuou...
Corresponding Author: Gianpiero Gravante, MD; e-mail: [email protected] Dear Editor, materials and techniques used for nasal reconstructions have always been a matter of discussion and still no clear guidelines are present. In the beginning, autologous cartilage grafts were extensively used for its low resorption and complication rates1-2. Recently, authors have preferred synthetic material...
