目的 探索皮肤伤口减张器在增生性瘢痕和瘢痕疙瘩切除术后,减少切口瘢痕形成和抑制瘢痕增生的作用。方法 选取10例增生性瘢痕和瘢痕疙瘩患者,行病理性瘢痕切除术,采用自身对照的方法,将瘢痕术后切口分为减张组和对照组。减张组瘢痕术后切口局部使用皮肤减张器,对照组瘢痕术后切口不使用减张器。定期随访3个月,比较两组瘢痕宽度、温哥华瘢痕量表评分,并进行统计分析。结果 与对照组相比,术后1、3个月减张组术后瘢痕宽度较对照组窄,温哥华瘢痕量表评分低,差异显著(P<0.05)。结论 皮肤伤口减张器对抑制手术后皮肤切口张力导致的瘢痕形成具有明确作用,能在一定程度上缩小瘢痕宽度、抑制瘢痕增生,从而提高增生性瘢痕和瘢痕疙瘩的手术治疗效果。

Objective To explore the effect of the skin tension reduction device on reducing scar formation after excisional surgery of hypertrophic scars and keloids. Methods Total 10 patients with hypertrophic scars and keloids were enrolled in this study. All of them received excisional surgery. Total 10 patients were involved as a self control study with part of wound treated with tendon reduction device, the other part with no treatment as control. All patients were observed for scar formation at surgical wound sites for 3 months post-surgery. Scar width and Vancouver scar scale were used as the parameter to quantify the differences between two groups. Results Compared with control group, the postoperative scar in tension reduction group was narrower in scar width and lower in the Vancouver scar scale scores with statistical significance （P〈0.05）. Conclusion Application of the skin reduction device can efficiently inhibit wound tension induced scar formation at post-surgery sites with significant reduction of scar width and hyperplasia after excisional surgery of hypertrophic scars/keloids.
