Split body comparative clinical and radiological study of fractional CO2 laser versus carboxytherapy in treatment of striae distensae

Striae Distensae (SD) are quite common complaint in dermatology practice. They are linear lesions of variable length and width according to the site and the causative condition. Several treatment modalities have been tried. To achieve satisfactory results, a combination therapy is often needed. To evaluate the efficacy and safety of fractional CO2 laser versus carboxytherapy in the treatment of Striae Distensae clinically and radiologically. Thirty Egyptian patients with striae distensae, received a split body therapy: the left side was treated by fractional CO2 laser and the right side was treated by carboxytherapy in the same session. Six sessions were done with 4 weeks apart. Clinical evaluation by measurement of the width of widest striae on both sides, global aesthetic improvement scale (GAIS), and Likert satisfaction scale. Radiological evaluation by measurement of cutaneous thickness of widest striae on both sides by ultrasonography. There was a highly statistically significant decrease in the median width of the widest striae distensae on both sides after the last session (P
