The incidence of keloid and hypertrophic change and of scar stretching in the presternal region were studied in a fair-skinned population following open heart surgery through a median sternotomy incision. No patient in this study developed keloid change although scar hypertrophy and stretching were frequent. These changes were unrelated to the material used in subcuticular suture of the skin in a comparison of catgut, prolene and polyglycolic acid. Hitherto, unrecognised differences of scar maturation between different areas of the presternal skin were noted to be statistically significant. Scar hypertrophy is most likely in that part of the scar overlying the body of the sternum and particularly in the female. Scar stretching occurs most frequently in the lower third of the scar overlying the xiphisternum and extending onto the abdomen.
在一个白种人群中，通过正中胸骨切开术切口进行心脏直视手术后，研究了胸骨前区瘢痕疙瘩、肥厚性改变及瘢痕拉伸的发生率。尽管瘢痕肥大和拉伸很常见，但本研究中没有患者出现瘢痕疙瘩改变。在比较肠线、普理灵和聚乙醇酸用于皮下皮肤缝合的材料时，这些改变与所用材料无关。此前，注意到胸骨前皮肤不同区域之间瘢痕成熟存在未被认识到的差异，具有统计学意义。瘢痕肥大最可能出现在覆盖胸骨体的瘢痕部位，尤其是女性。瘢痕拉伸最常发生在覆盖剑突并延伸至腹部的瘢痕下三分之一处。
