OBJECTIVE To compare the biomechanical properties of the superficial (human acellular dermis); (AlloDerm; LefeCell Corp, Branchburg, NJ) and deep layers of cadaveric dermis and expanded polytetrafluoroethylene (ePTFE); (Gore-Tex; W. L. Gore & Associates, Flagstaff, Ariz). METHODS Sixteen samples of superficial dermis (AlloDerm), 12 samples of deep dermis, and 12 samples of ePTFE were axial lo...

Several studies have reported on certain aspects of the characteristics of different sites within a keloid lesion, but detailed studies on the keloid dermis at different depths within a keloid lesion are scarce. The aim of this study was to investigate the histology of the keloid dermis at different depths. This study included 19 keloid tissue samples that were collected from 19 patients and 19...

Skin of 14-day icjic and + / + embryos was separated into dermal and epidermal layers using trypsin, and recombined in the combinations + /+ epidermis with + /+ dermis, +/ + epidermis with icfic dermis, icjic epidermis with + /+ dermis, and icjic epidermis with ic/ic dermis. The recombined tissues were implanted in adult histocompatible testes and allowed to grow for 2 weeks. The type of hair t...

background: this study aimed to assess dermis fat graft (dfg) as a choice to correct the tissue deficit in the free border of the upper lip in cleft lip repair surgery. materials and methods: thirty?five individuals who referred to alzahra hospital at 2013–2014,with lip deformity following the primary repair surgery of cleft lip underwent surgery by dfg technique. outcomes were assessed 4 month...

Limitations of synthetic biomaterials for abdominal wall repair have led investigators to seek naturally derived matrices, such as human acellular dermis, because of their excellent biocompatibility and their ability to naturally interface with host tissues with minimal tissue response. In this study, we investigated two different biomaterials derived from human dermis (FlexHD acellular dermis ...
