A versatile local skin flap for the closure of facial defects is presented. A tangent is drawn to the edge of a circular defect parallel to the relaxed skin tension lines for a distance of 1.5 diameter (d); a second line of length d is drawn at 50 degrees to 60 degrees to the first to create a triangular flap. The final flap design when drawn resembles an(More)
The osteoinductive properties of demineralized bone have stimulated its use in facial skeletal augmentation and reconstruction. Demineralized bone has been shown to induce phenotypic conversion of mesenchymal cells into osteoblasts, with bone formation within 29 days (osteoinduction). In this clinical study, 75 demineralized bone implants were followed up(More)
