It is concluded that dominator can hold competing vantage by suppressing its opponent, and besides, whether competing technology can gain superiority in diffusion process depends on the success rates of technology diffusion when the two kinds of technology match each other in strength.展开更多

Methods We modified the dissection of the subpectoral space by extending it over the sternum edge 1cm medially and beyond the breast crease 2cm inferiorly, yet keeping strictly the upper border of the space on the third rib and the lateral border on the anterior axillary line. Results All 50 patients were satisfied with their augmented breasts which nearly resembled the virginal ones. Conclusion Our modified dissection enabled the mammary implant to stay in the position where it originally was and not be pushed upward and laterally by the pectoral muscle contraction as usually seen by the traditional technique.展开更多
