Fractional CO2 laser therapy for cesarean scar under the guidance of multiple evaluation methods: A retrospective study

Abstract Aims To introduce the treatment experience of fractional CO 2 laser for cesarean scar under the guidance of multiple evaluation methods. Methods Cesarean scar patients receiving fractional CO 2 laser therapy between January 2016 and January 2020 were retrospectively analyzed in this study. The demographic characteristics and treatment protocols, the Vancouver Scar Scale (VSS), the University of North Carolina “4P” Scar Scale (UNC4P), and the Antera3D score of all the enrolled patients were recorded. Results Altogether, 79 cesarean scar patients were involved in this study, with the average age of 28.1 years, the average scar age and length of 26.5 (range, 24‐30) months and 8.5 (range, 7‐11) cm, respectively. Significant improvements were observed in VSS ( t = 16.75, P < .05), UNC4P ( t = 15.63, P < .05), and Antera3D score (color: t = 13.19, P < .05; texture: t = 13.12, P < .05; melanin: t = 3.89, P < .05; hemoglobin: t = 2.28, P < .05). No long‐term complication was reported during the follow‐up visits. Conclusions Fractional CO 2 laser therapy is an effective treatment for cesarean scar. The multiple evaluation methods, including the combined application of VSS, UNC4P, and Antera3D score, can be potentially used for guiding treatment protocols and evaluating efficacy. Meanwhile, rhGM‐CSF hydrogel provides another choice for laser wound management.
