OBJECTIVE The epidural fluid collection (EFC) as a complication of cranioplasty is not well-described in the literature. This study aimed to identify the predictive factors for the development of EFC as a complication of cranioplasty, and its outcomes. METHODS From January 2004 to December 2012, 117 cranioplasty were performed in our institution. One-hundred-and-six of these patients were cla...

The aim of this study was to evaluate the osteocalcin immunoexpression during the bone repair treated with subcutaneous adipose tissue in rats and rabbits. Fourteen rats and 14 rabbits were used in the study. A critical-sized calvarial defect was created in each animal. The animals were divided into 4 experimental groups: RC (rat control), RbC (rabbit control), RAT (rat adipose tissue), RbAT (r...

introduction : efforts are being made to improve the efficacy of biomaterials used as bone substitutes for bone regeneration in the oral and maxillofacial region. graft materials have been recently produced in iran; however, studies are required to confirm their efficacy. this study aimed to compare the histomorphometric results of using mineralized allografts produced by the hamanandsaz baft k...

The membranous bones of the mammalian skull vault arise from discrete condensations of neural crest- and mesodermally-derived cells. Recently, a number of homeodomain transcription factors have been identified as critical regulators of this process. Here, we show that the homeoprotein engrailed 1 (EN1) is expressed during embryonic and perinatal craniofacial bone development, where it localizes...
