Background
Post-burn hypertrophic scar and keloid are challenging problems. Intense pulsed light (IPL) vascular filter (550–1200nm) has a similar effect to the pulsed dye laser 585nm in management of the same cutaneous applications.
Methods
This prospective comparative study was conducted on 34 patients with post-burn hypertrophic scars and keloid. The lesions were irradiated, using an IPL filter 550–1100 nm, 20 ms pulse duration, and fluence of 34 J/cm2. Sessions done every 2 weeks over a period of 6 months. The follow-up was scheduled for 1 month and 6 months. Evaluation methods were both subjective by the Vancouver scar scale (VSS) and objective by the skin imaging analysis system.
Results
Patients received 12 sessions. Erythema was the first sign to show improvement after the second session while itching was the first symptom which showed improvement followed by pain and finally improvement in the range of movement. The improvement of the VSS was higher in the hypertrophic scars than the keloid group (P˂ 0.001).
Conclusions
IPl proved its efficacy in the treatment of post-burn hypertrophic scars and keloid. However, the improvement in the pliability and erythema in hypertrophic scar was higher than in keloids.
