Objective To evaluate efficacy and safety of fractional CO2 laser treatment versus fractional CO2 with subcision in the management of atrophic postacne scars. Background Atrophic postacne scarring has always been a challenge to treat. Fractional CO2 resurfacing in combination with subcision is effective and well tolerated. Patients and methods This prospective study includes 50 patients with atrophic acne scars from Outpatient Clinic of Dermatology, Andrology and STDs Department. An informed consent was obtained. Patients from both sex at least 18 years with any types and any grade of atrophic postacne scars, and not receiving any treatment in the past 6 months for their scars were included. All patients were subjected to history taking, general examination, and qualitative grading of acne. Patients were divided into two groups: group A included 25 patients who were subjected to fractional CO2 laser, and group B included 25 patients who were subjected to subcision and fractional laser on the second day of subcision. Results Excellent satisfaction was 100% with grade 1 scar, and good satisfaction was more common with grade 2 scar (60%) in group A. There were highly statistically significant differences found between grade of scar and patient satisfaction in group A (P = 0.001). Excellent satisfaction was 90.91% with grade 1 scar, and good satisfaction was more common with grade 1 scar (57.14%) in group B. There were statistically significant differences found between grade of scar and patient satisfaction in group B (P = 0.028). Conclusion The combination of fractional carbon dioxide laser and subcision is safe and effective modality for the treatment of atrophic acne scars. Moreover, there were improvements in patient satisfaction, without considerable complication.
