Microsurgical reconstructions of the face using free flaps from the body and the extremities often lead to imperfect aesthetic results. In order to find the optimal free-flap donor site with respect to its colour we compared the colour of the face and of typical free-flap donor sites. In a study of 19 healthy, untanned subjects with skin type II-III (Fitzpatrick 1988), we measured the colour of four facial areas and of ten common free-flap donor sites and compared them statistically. Measurements were carried out with a Minolta CR-300 chromameter and the CIELAB colour system. We found that the face itself can be divided into two statistically significant different colour regions. The forehead-, cheek- and mandible areas have a distinctly different colour than the nose. The donor sites showing the best colour match with the forehead-, cheek- and mandible area were pectoralis, lateral upper arm, radialis, fibula, and latissimus. The nose area is clearly darker and less colourful. For this reason the colour match of all the free-flap donor sites in our investigation is poorer. Here the best suited donor site area is still the dorsalis pedis area.
使用来自身体和四肢的游离皮瓣对面部进行显微外科重建，往往会导致不理想的美学效果。为了找到在颜色方面最佳的游离皮瓣供区，我们比较了面部与典型游离皮瓣供区的颜色。在一项针对19名皮肤类型为II - III型（Fitzpatrick，1988）的健康、未晒黑受试者的研究中，我们测量了四个面部区域和十个常见游离皮瓣供区的颜色，并进行了统计学比较。使用美能达CR - 300色差仪和CIELAB颜色系统进行测量。我们发现面部本身可分为两个在统计学上有显著差异的颜色区域。额头、脸颊和下颌区域的颜色与鼻子明显不同。与额头、脸颊和下颌区域颜色匹配最佳的供区是胸大肌、上臂外侧、桡侧、腓骨和背阔肌。鼻子区域明显更暗且颜色更单一。因此，在我们的研究中，所有游离皮瓣供区的颜色匹配都较差。这里最合适的供区仍然是足背区域。
