| Popis: | The appearance and symptoms of scars can cause significant distress to patients.To assess and compare efficacy of the 1,500-nm nonablative fractional laser (NAFL) and 10,600-nm ablative fractional laser (AFL) in reducing symptoms and improving the appearance of traumatic or surgical scars.Single-center prospective, randomized, blinded, split-scar study was conducted on 100 patients with a scar obtained through trauma or surgery. Three treatments of NAFL or AFL were administered to each half of the scar at 4-week intervals. Scars were self-rated by the patient using the Patient and Observer Scar Assessment Scale and a satisfaction score and objectively evaluated by blinded dermatologists using the Manchester Scar Scale and visual analog scale.Blinded observers found no statistically significant difference in scar appearance. Patient rating showed improvement of scar appearance (p.0001). Pain was worse after treatment with AFL (p = .0492). Overall, there was no statistically significant evidence of one laser being superior or inferior to the other for patient and blinded observer scores (p = .3173 and p = .2513, respectively).Scar treatment with AFL or NAFL is associated with high patient satisfaction. Objective evaluation of scars did not identify improvement in scar appearance. |
