Z成形术在面部直线瘢痕美容修复中的应用

Application of Z plasty in the aesthetic repair of facial linear scar

【目的】探讨Z成形术在面部直线型瘢痕修复中应用的可行性和合理性。【方法】选择2009年7月-2011年7月我院整形科接受Z成形术修复的50例面部瘢痕患者作为治疗组,另选取2007年7月-2009年7月我院整形科接受单纯面部瘢痕切除缝合的47例患者作为对照组。采用OSAS瘢痕评价量表,由两位观察者对瘢痕的颜色、平整度、弹性、宽度进行评判打分,术前和术后、治疗组和对照组进行对比。【结果】术前治疗组和对照组的比较无明显统计学差异(P>0.05)。对照组术后瘢痕的颜色、平整度、弹性和宽度均有很大改善,与术前相比具有显著统计学差异(P<0.05)。治疗组术前、术后相比无论从瘢痕的颜色、平整度还是弹性和宽度均有明显的改善,两者相比具有显著统计学差异(P<0.05)。治疗组术后和对照组术后相比,瘢痕颜色更淡、瘢痕更平整、弹性更好、宽度明显缩窄,两者相比具有显著统计学差异(P<0.05)。【结论】Z成形术应用于面部直线型瘢痕的修复可以明显改善瘢痕的术后效果,是一种操作简便,值得临床推广的手术方法。

[ Objective ] To explore the feasibility and rationality of using Z plasty to repair facial linear scar. [ Methods ] Fifty cases of facial linear scar, had been underwent with scar resection and Z plasty from 2009/7 to 2011/7, were selected as the treated group. Forty-seven facial scar cases, had been underwent simple scar resection were selected as the control group. The scar colour, smoothness, elasticity and width were assessed by two observers with OSAS. The data were analyzed and compared. [ Results] There was no statistical difference between the treated group and the control group before operation（P〉 0.05）. There was statistically significant difference between the pre- and post-operation of the control group（P〈O.05）. There was also statistically significant difference between the pre- and post-operation of the treated group（P 〈 0.05）. The post-operation scar of the treated group had lighter colour, more smoother surface, better elasticity and narrower width as compared with the control group. The statistical difference was significant between the two post-operation groups（P 〈 0.05）. [ Conclusion ] Z plasty could obviously improve the operative effect of the facial linear scar. Z plasty is a simple method and worthy of promoting clinically.
