A procedure for duplication of cranial bone flaps used in cranioplasty is described. This procedure overcomes the difficulties inherent in direct duplication of irregular-shaped bone flaps through primary replication of the flap in wax. The wax pattern is used to fabricate the definitive prosthesis.

In this paper, a recent operating technique that consists of using perforator instead of axial flaps in reconstructive surgery is investigated from the hemodynamic point of view. By means of a mathematical modeling resting on the fluid dynamical aspects of the technique, we describe the hemodynamic enhancements with respects to the classical surgical method. Finally, we report some clinical dat...

Perforator flaps represent the latest in the evolution of soft tissue flaps. They allow the transfer of the patient’s own skin and fat in a reliable manner with minimal donor-site morbidity. The powerful perforator flap concept allows transfer of tissue from numerous, well-described donor sites to almost any distant site with suitable recipient vessels. The inferior gluteal artery perforator (I...

BACKGROUND One of the main challenges in skin flap surgery is tissue ischemia and following necrosis. The present study compares the effects of fibroblast growth factors 1 and 2 on increasing cutaneous vasculature, improving ischemia, and preventing distal necrosis in ischemic skin flaps in rat model. METHODS Thirty rats were allocated into 3 groups (n=10) and 2×8 cm dorsal rando...

BACKGROUND Necrosis of skin flaps is considered as an important complication in reconstructive surgery. We conducted an experimental study to investigate the efficacy of low-molecular weight heparin, clopidogrel and their combination to improve the flap survival. METHODS Forty male, adult Sprague-Dawlay rats were divided randomly into 4 groups. Standard rectangular, distally based dorsal ran...

BACKGROUND After wide local excision of cutaneous melanoma, large defects not amenable to simple primary closure are often covered with skin grafts. We report our experience using the rhomboid and keystone flaps to immediately close large axial and extremity wounds after potentially curative surgery for non-head and neck melanomas. METHODS Between January 2011 and September 2016, demographic,...

As a result, the purpose of this study was identification the components of evaluation of employee performance smart pattern. Methodology: This study in terms of purpose was applied and in terms of implementation method was qualitative. The research population was specialist ma...

This study was conducted to investigate the possibility of improving the success rate of patient treatment and promoting wound healing by utilizing xenogenic (porcine) acellular dermal matrix (XADM) to cover large areas of severely damaged wounds. Patients with severely damaged large-area wounds (56 cases) were enrolled in the study from May 2002 to May 2012. All patients admitted to hospital r...
