In this paper, the subject of surface-area gain in tissue expansion is approached from three sides. With the help of a mathematical approach, the theoretical increase in surface area was calculated in relation to the specifications of the expanders. In an in vitro model, these mathematical data were confirmed to be reliable. To determine the real surface-area gain that takes place in vivo, measurements on pigs were performed. It appears that only about 35 percent of the mathematically expected increase in surface area takes place. Moreover, a clear difference was observed between the surface-area gain for the different shapes of tissue expanders.
在本文中，从三个方面探讨了组织扩张中表面积增加的问题。借助数学方法，根据扩张器的规格计算了表面积的理论增加量。在体外模型中，证实这些数学数据是可靠的。为了确定体内实际发生的表面积增加量，对猪进行了测量。结果表明，实际发生的表面积增加量仅约为数学预期增加量的35%。此外，观察到不同形状的组织扩张器在表面积增加方面存在明显差异。
