摘要
目的探求可靠实用的测量扩张皮肤面积的方法。方法先将三维表面上的扩张皮肤通过表面取模后,分剪成二维平面。通过扫描仪直接输入后,利用计算机处理累计其像素点,从而客观测量出扩张皮肤面积。同法测量扩张基底面积和缺损面积后,能确定扩张后额外皮肤面积是否能满足修复需要。结果经初步论证,其最大误差小于3%。结论这一技术可望在临床和动物实验研究中提供扩张皮肤面积测量的可靠指标。
Objective To seek a reliable and practical method to measure the expanded skin area. Methods In our technique,the three-dimensional surface overlaid with the expanded skin was converted to a flat one through a special surface molding.This irregular plane area was scanned digitally to the com- puter and measured by means of counting its total pixels.With the areas of the underlying base and the de- fect measured in the same way,we could determine whether the extra tissue after expansion was sufficient for clinical repair at any stage of expansion.Results The deviation of this protocol was less than 3 percent at most in our preliminary reliability demonstration.Conclusion This protocol can be used to estimate the expanded skin area in the clinical and experimental applications.
