UNASSIGNED:本研究的目的是比较点阵CO2激光和1,550nmEr:glass激光治疗白纹患者的疗效和安全性。
UNASSIGNED：招募了腹部有纹至少12个月的女性成年人。在获得知情同意后，患者每2个月接受三次治疗.左腹部病变用10,600nmCO2点阵激光治疗，右侧用1,550nmEr：玻璃点阵激光治疗。在每次访问之前和最终治疗后3个月拍摄照片。使用四分位数分级量表进行评估的标准非常好（76-100％），良好（51-75%），公平（26-50%），差（1-25%），没有改善（0%）。由两名皮肤科医生使用前后照片独立评估两种激光的安全性和有效性。此外,还记录了调查患者疼痛和满意度的自我报告.
未经批准：完全，招募了27例，25例患者完成治疗和随访。84％的患者在右腹部取得了良好的效果（改善51-100％），而左边为48%(p<0.05)。在左腹部评估的患者中，有20％的患者出现色素沉着过多，在右腹部仅占8％。在治疗期间,右腹部疼痛的平均评分为5.41±2.13，高于左侧（4.19±2.12）（p<0.001）。两侧均未发现永久性色素沉着。考虑到整个治疗，患者更喜欢右侧使用的方式(80vs.68%,p<0.05)。
UNASSIGNED：与CO2分数激光相比，1,550nmEr：玻璃点阵激光治疗在治疗白纹方面提供了显着更好的临床效果和更少的副作用。
UNASSIGNED：样本量和随访时间有限。
UNASSIGNED: The objective of this
study was to compare the efficacy and safety of fractional CO2 laser and 1,550 nm Er: glass laser in the treatment for the patients with striae albae.
UNASSIGNED: The female adults with striae albae in the abdomen for at least 12 months were recruited. After informed consent obtained, the patient received three treatments at 2-month intervals. The lesions on the left abdomen were treated with 10,600 nm CO2 fractional laser and right side treated with 1,550 nm Er: glass fractional laser. The pictures were taken before each visit and 3 months after the final treatment. The criteria for the evaluations using a quartile grading scale were excellent (76-100%), good (51-75%), fair (26-50%), poor (1-25%), and no improvement (0%). The safety and efficacy of the two lasers were independently evaluated using before and after photographs by two dermatologists. In addition, the self-reports to investigate the pain and satisfaction from patients were also recorded.
UNASSIGNED: Totally, 27 cases were recruited, and 25 patients completed the treatments and follow-up. The excellent and good results (improvement of 51-100%) were achieved on the right abdomen in 84% of the patients, while 48% on the left site (p < 0.05). Hyper-pigmentation was seen in 20% of the patients assessed on the left abdomen and only in 8% on the right abdomen. During the treatments, average score of the pain on the right abdomen was 5.41 ± 2.13, which was higher than that on the left (4.19 ± 2.12) (p < 0.001). No permanent hyper-pigmentation was found on the both sides. Considering the whole treatments, the patients favored the modality used on the right side (80 vs. 68%, p < 0.05).
UNASSIGNED: Compared with CO2 fractional laser, 1,550 nm Er: glass fractional laser therapy provides the significantly better clinical outcomes and fewer side effects in the treatment of striae albae.
UNASSIGNED: The sample size and follow-up time were limited.
