Approaches to improve keloid scars include intralesional corticosteroid injections and fractional lasers exclusively. The combinative use of ablative fractional laser therapy and occluded topical corticosteroid as a drug delivery method enhances therapeutic outcome of two efficient scar therapy modules into one simple synergistic module.
To compare the therapeutic effect of combining two modalities of scar treatment, the first is fractional ablative laser treatment and the other is occluded topical corticosteroid to the standard use of intralesional steroid injection.
Keloids from thirty suffering patients were split faced into two identical parts; one part received an intralesional corticosteroid injection while the other part was treated first with fractional ablative 2940 nm Er: YAG laser followed by occluded topical application of steroid cream. Four treatment sessions were performed with 4-week interval between sessions. Every session was assessed photographically and using the Vancouver Scar Scale (VSS).
The mean keloid VSS before treatment was 6.9 ± 1.9. After treatment, the mean keloid VSS of the injection side became 2.63 ± 2.09, and mean keloid VSS of the laser-treated side became 2.07 ± 2.02. Each of the treated halves showed a statistically significant improvement in their VSS. However, no statistically significant differences were observed for either of the treated halves over the other one.
Although intralesional steroids injection is the standard procedure for treatment of keloid scars, the use of ablative fractional laser-assisted delivery of topical steroid can offer a safer and a better aesthetic treatment option.
改善瘢痕疙瘩的方法仅包括病灶内注射皮质类固醇和分次激光治疗。将剥脱性分次激光治疗与封闭性外用皮质类固醇作为一种药物递送方法相结合,可将两种有效的瘢痕治疗模式的治疗效果提升为一个简单的协同模式。
比较两种瘢痕治疗方式(第一种是分次剥脱性激光治疗,另一种是封闭性外用皮质类固醇)与病灶内注射类固醇的标准治疗方法的治疗效果。
将30例瘢痕疙瘩患者的瘢痕分为两个相同的部分;一部分接受病灶内皮质类固醇注射,另一部分先接受2940nm铒:钇铝石榴石剥脱性激光治疗,然后外用类固醇乳膏封闭治疗。共进行4次治疗,每次治疗间隔4周。每次治疗后通过拍照和使用温哥华瘢痕量表(VSS)进行评估。
治疗前瘢痕疙瘩的平均VSS为6.9±1.9。治疗后,注射侧瘢痕疙瘩的平均VSS变为2.63±2.09,激光治疗侧瘢痕疙瘩的平均VSS变为2.07±2.02。每侧治疗后的VSS均有统计学意义的改善。然而,两侧治疗后的VSS在统计学上没有显著差异。
虽然病灶内注射类固醇是治疗瘢痕疙瘩的标准方法,但使用剥脱性分次激光辅助递送外用类固醇可提供更安全、美观的治疗选择。
