The objective of preventing surgical scar formation is to improve the quality of life for patients. Many medical products have been used in preventing hypertrophic scarring but an optimal treatment method has not been established yet. At the present, there are several studies demonstrating the potential of herbs in scar prevention. The purpose of this study was to evaluate the efficacy of combined herbal extracts gel (CHG) in the prevention of surgical scar formation.
All the patients who underwent bilaterally symmetric surgical procedures were selected using inclusion and exclusion criteria and were then treated with both the CHG (CHG group) and placebo gel. Each gel was applied on separate scars twice daily for 12 weeks. The scars were photographed and evaluated using Patient and Observer Scar Assessment Scale (PSAS and OSAS, respectively).
The CHG-treated scars showed lower median PSAS scores than the placebo group in color, stiffness, thickness, irregularity, and overall scores, with statistically significant difference at 12 weeks. For OSAS, the scars in the CHG group showed lower median scores than the placebo group in pigmentation, thickness, and overall scores at 12 weeks. The median OSAS scores in vascularity, relief, and pliability differed from placebo group and were statistically significant at 8 weeks. No side effects were observed in either group.
The CHG might be effective in the prevention of surgical scarring.
预防手术瘢痕形成的目的是提高患者的生活质量。许多医学产品已被用于预防增生性瘢痕形成,但尚未建立最佳的治疗方法。目前,有几项研究表明草药在预防瘢痕方面具有潜力。本研究旨在评估联合草药提取物凝胶(CHG)在预防手术瘢痕形成中的疗效。
所有符合纳入和排除标准的接受双侧对称手术的患者,均采用 CHG(CHG 组)和安慰剂凝胶进行治疗。两种凝胶均在 12 周内每天两次涂于单独的瘢痕上。对瘢痕进行拍照,并分别使用患者和观察者瘢痕评估量表(PSAS 和 OSAS)进行评估。
CHG 治疗的瘢痕在颜色、硬度、厚度、不规则性和总体评分方面的 PSAS 评分中位数均低于安慰剂组,在 12 周时具有统计学意义。对于 OSAS,CHG 组的瘢痕在色素沉着、厚度和总体评分方面的中位数评分均低于安慰剂组,在 12 周时具有统计学意义。血管生成、缓解和柔韧性的 OSAS 评分中位数与安慰剂组不同,在 8 周时具有统计学意义。两组均未观察到不良反应。
CHG 可能对预防手术瘢痕形成有效。
