Striae distensae (SD) are a type of dermal scarring that is quite common and difficult to treat. Two forms are known: striae rubrae (SR) and striae albae (SA).
We compared the long-term clinical effectiveness of a 1550-nm non-ablative fractional laser (NAFL) in treating SR and SA.
We included 16 female patients (8 with SR and 8 with SA) who had developed abdominal SD during pregnancy. All underwent five moderately high-energy sessions of 1550-nm NAFL treatment at 4-week intervals. The strial widths and lengths were measured before, and 1 month and 1 year after treatment.
The mean strial width decreased from 6.94 mm before treatment to 3.25 mm at the first follow-up visit (p = 3.95 × 10) and to 3.13 mm at the second follow-up visit (p = 2.44 × 10). Similarly, the mean strial length decreased from 6.06 to 2.88 cm at the first follow-up visit (p = 1.7 × 10) and to 2.75 cm at the second follow-up visit (p = 9.52 × 10).
NAFL treatment was effective long term in both SR and SA patients.
膨胀纹（SD）是一种常见且难以治疗的皮肤瘢痕。已知有两种类型：红色膨胀纹（SR）和白色膨胀纹（SA）。
我们比较了1550纳米非剥脱性分次激光（NAFL）治疗SR和SA的长期临床疗效。
我们纳入了16名在孕期出现腹部SD的女性患者（8例SR患者和8例SA患者）。所有患者均接受了5次中等能量的1550纳米NAFL治疗，间隔4周。在治疗前、治疗后1个月和1年测量膨胀纹的宽度和长度。
平均膨胀纹宽度从治疗前的6.94毫米降至首次随访时的3.25毫米（p = 3.95×10），第二次随访时降至3.13毫米（p = 2.44×10）。同样，平均膨胀纹长度从6.06厘米降至首次随访时的2.88厘米（p = 1.7×10），第二次随访时降至2.75厘米（p = 9.52×10）。
NAFL治疗对SR和SA患者长期有效。
