Several modalities have been advocated to treat traumatic scars, including surgical techniques and laser resurfacing. Recently, a plasma skin regeneration (PSR) system was investigated. Twenty Asian patients with traumatic scars were treated with PSR system. Three treatments were performed at monthly intervals with PSR, using energy settings of 2 to 3J. Nine of 20 patients showed more than 50% improvement. The average pain score on a 10 point scale VAS score was 5.8 +/- 1.3SD and all patients tolerated the treatments. The average re-epithelization time was 7.3 +/- 2.8SD days. Temporary and local hyperpigmentation was observed in four patients and this hyperpigmentation disappeared within three months. Hypopigmentation and worsening of scarring were not observed. Plasma treatment is clinically effective and is associated with minimal complications when used to treat traumatic scars Asian patients. However, deep traumatic scars are resistant to plasma treatment. More recently, fractional non-ablative and ablative laser have been used to treat traumatic and acne scars. There is a possibility of achieving better improvement of deep scars. Further studies are warranted to evaluate these treatments.
