Stretch marks, or striae distensae, are dermal scars and result in considerable aesthetic concern. The responsible factors for their development are poorly understood. Development of striae distensae is a rare complication after breast augmentation. Successfully treating striae distensae has always been challenging. Lasers and light devices have recently become a good therapeutic option. The fractional laser has shown encouraging results with less risk of pigmentation in the treatment of recent stretch marks.
Forty-seven patients underwent breast augmentation over a period of 2 months; of these, 10 patients developed new striae distensae. They were submitted to nonablative fractionated 1550-nm erbium glass laser treatment. Response was assessed from photographs obtained before and 4 weeks after the end of treatment. Two plastic surgeons analyzed improvements clinically and photographically, and a patient satisfaction score was recorded as well.
There was a significant relationship between age and development of striae, (p = 0.003), but there was no significant relationship between striae distensae and nulliparity (p = 0.147), volume of the silicone implant (p = 0.892), or use of oral contraceptive (p = 1.00). The scores achieved by both the evaluators and the patients were high, with 50 percent of them between 9 and 10 (maximum scores), and with a high index of satisfaction with the treatment.
Age is statistically significant in the development of striae distensae after breast augmentation. This report demonstrates excellent patient and plastic surgeon satisfaction after treatment. The use of fractional photothermolysis is a good treatment modality for striae rubrae.
妊娠纹，或伸展纹，是皮肤疤痕，会引起相当大的美观问题。其发展的相关因素尚未完全清楚。乳房增大后发生伸展纹是一种罕见的并发症。成功治疗伸展纹一直具有挑战性。最近，激光和光设备已成为一种很好的治疗选择。在治疗近期伸展纹时，分数激光显示出令人鼓舞的结果，并且色素沉着的风险较低。
在 2 个月的时间内，有 47 名患者接受了乳房增大手术；其中 10 名患者出现了新的伸展纹。他们接受了非消融性分数 1550nm 铒玻璃激光治疗。在治疗结束前和 4 周后拍摄照片评估反应。两名整形外科医生从临床和照片上分析了改善情况，并记录了患者满意度评分。
年龄与伸展纹的发展之间存在显著关系（p=0.003），但伸展纹与未婚（p=0.147）、硅胶植入物的体积（p=0.892）或口服避孕药的使用（p=1.00）之间无显著关系。评估者和患者的评分都很高，其中 50%的评分在 9 到 10 之间（最高评分），并且对治疗的满意度很高。
年龄在乳房增大后伸展纹的发展中具有统计学意义。本报告表明，分数光热解治疗后患者和整形外科医生的满意度都很高。分数光热解的使用是治疗红色伸展纹的一种很好的治疗方法。
