双波长非剥脱点阵激光“水增强法”治疗面部凹陷性瘢痕的疗效观察

Curative effect of double wavelength non -stripping lattice array laser "water enhancement method" in the treatment of facial sunken scar

目的观察双波长非剥脱点阵激光“水增强法”治疗面部凹陷性瘢痕的疗效.方法选择2017年6月至2018年2月嘉兴市中医医院收治的面部凹陷性瘢痕患者50例为研究对象,采用随机数字表法分成观察组和对照组,每组25例,观察组采用注射利多卡因联合双波长非剥脱性点阵激光进行治疗,对照组采用双波长非剥脱性点阵激光进行治疗,比较两组患者的临床治疗效果;结果观察组治愈率为60. 00%(15/25),对照组治愈率为36. 00%(9/25),观察组治愈率显著高于对照组,两组差异有统计学意义(χ^2=32. 524,P<0.05).结论对面部座疮后凹陷性瘢痕患者,运用水辅助1540 nm点阵激光治疗,能够得到显著的治疗效果,并且安全性较好,不良反应少,是目前最适合亚洲連疮凹陷性瘢痕患者的治疗方案。

Objective To evaluate the efficacy of dual - wavelength non - stripping dot array laser " water enhancement" in the treatment of facial sunken scar. Methods From June 2017 to February 2018 , fifty patients with facial sunken scar were randomly divided into observation group and control group according to the digital table, with 25 cases in each group. The observation group was treated by lidocaine injection combined with dual - wavelength non -stripping lattice laser,while the control group was treated with double - wavelength non - stripping dot array laser. The clinical therapeutic effects of the two groups were compared and analyzed. Results The cure rate of the observation group was 60. 00%( 15/25), which was significantly higher than that of the control group [ 36. 00%(9/25 )], and the difference between the two groups was statistically significant ( χ^2=32. 524,P <0. 05 ). Conclusion Water assisted 1540 nm lattice laser therapy for facial sunken scar after acne has obviously better effect, safety and less adverse reactions. And it is the most suitable treatment for patients with facial sunken scar after acne in Asia.
