对330例体表创口与愈后瘢痕长度的对比观察

探讨体表创口与愈后瘢痕相互关系。在 330例不同年龄的伤者的不同部位的钝、锐器伤口 ,用精确的测量方法 ,在伤后 3d内、伤后 1个月、伤后 3个月进行测量 ,并计算创口愈合成为瘢痕的收缩率。在伤后 3个月面部瘢痕的收缩率为 15 4% ,躯干、四肢瘢痕收缩率为 13 6 % ,头皮瘢痕收缩率为 10 1%。不同致伤物形成的创口 ,在伤后 3个月时 ,不规则钝器创的瘢痕收缩率为 16 1% ,锐器创的瘢痕收缩率为 11 2 %。结果表明 ,创口在伤后 3个月时 ,面部瘢痕收缩率最大 ,头皮瘢痕收缩率最小。不规则钝器创的瘢痕收缩率值比锐器创的瘢痕收缩率值大。

Comparison of the lengths of wound and the lengths of the scar in 330 mechanical injury cases

The present paper reports the comparison of the lengths of the constriction rate of the mechanical wounds located on the different parts of the bodies in 330 cases.The constriction rate was obtained by comparing the length of the fresh wound with the scar measured 3 days,1 month and 3 months after injury.The results were as follows:the constriction rates of the wounds on the face,trunk and limb,as well as on the scalp were 15 4%,13 6%,and 10 1% respectively,while those of the wounds caused by the irregular object and the sharp object were 16 1% and 11 2% respectively.The former were larger than the later.The results demonstrated that the constriction rates of wound on the face were the largest,while those of wounds on the scalp were the smallest.
