超脉冲CO2激光联合点阵铒激光治疗面部瘢痕的临床研究

Clinical study of the treatment of facial scar with ultrapulse CO2 laser and Erbium fractional laser

目的 观察超脉冲CO2激光联合点阵铒激光治疗面部瘢痕的效果.方法 对70例面部瘢痕患者,采用超脉冲CO2激光和点阵铒激光联合治疗3次;治疗间隔为2～3个月.首先使用超脉冲CO2激光磨削,功率1～2 W,输出时间0.02 s,延迟时间1.12 s.然后使用点阵铒激光治疗,波长为2940 nm,能量500～800 mJ,光斑直径2～7 mm.结果 治疗结束后随访3～6个月,显效者51例,有效者19例.主要并发症为短暂红斑、水肿、色素沉着.结论 超脉冲CO2激光与点阵铒激光联合治疗面部瘢痕,具有疗效好、损伤小、术后恢复快、并发症少等优点.

Objective To ohserve the effect of uhrapulse CO2 laser combined with Erbium fractional laser on the treatment facial scars. Methods Total 70 cases with facial scars were treated with ultrapulse CO2 laser combined with Erbium fractional laser for 3 times with 2 - 3 months interval. Firstly, Sear resurfacing was performed utilizing uhrapulse CO, laser with the power 1 - 2 W, the output time 0.02 s, the delay time 1.12 s, and then the 2940 nm Erbium fractional lase was used at settings of 500 - 800 mJ of the energy, 2 - 7 mm of the light spot. Results Patients were followed up for 3 months after the last treatment, 64 eases were graded as excellent clearance, 6 eases were good clearance. Common complications in this study were transient erythema, edema and hyperpigmentation. Conclusion Combination of ultrapulse CO2 laser and Erbium fraetional laser is a novel therapy for facial scar, which is considered to be beneficial because of the advantages such as well curative effect, minimal invasion and short recover＇ and few complications.
