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. |
