Patients and methods This is a prospective study of 25 patients (skin types IIHV, aged 6-37 years) tyith stable:. nonhypertrophic scars who underwent at least three sessions with a fractional CO, laser at 1-month interval.. Side effects as well as improvements in texture, atrophy, and overall satisfaction with appearancewere graded on a quartite scale bythe patients^andjnvestigators after each treatment and 4weeks after the final treatment Before-after scoreswere compared using the Student f-test,with significance assigned to Pvalues less than 0.05. Results All patients showed clinical improvement. There was no significant difference between the assessment of the investigator and the two blinded dermatologists.;In.terms pf, patient . satisfaction, 32%of patientswere not satisfied to slightly satisfied, whereas 68%were satisfied ' and 20%were very satisfied to extremely satisfied. Side effectswere minimal and transient. Conclusion Fractional CO2 laser treatment represents a safe, well-tolerated, effective, and promising treatment modality for nonhypertrophic traumatic and postinflammatory scars, with minimal downtime and fewer side effects.
