Abstract:

Objective　To explore the experience of laser treatment for finger contracture scars in children. Methods　A

retrospective before-after self-control study was conducted. Thirty patients with finger contracture scars from December 2021

to December 2022 were admitted. Among them, 17 cases of scars with red appearance and obvious congestion were treated with

pulsed dye laser (PDL, 585 nm) combined with ultra pulse carbon dioxide lattice laser, while 13 cases of skin scars were treated

with ultra pulse carbon dioxide lattice laser alone. Each patient was treated three times, with a 2-month interval between each

treatment. Before and after treatment, the Vancouver Scar Scale (VSS) was used to score the scar condition, and the changes in

the range of motion of the affected joint before and after treatment, as well as the occurrence of adverse reactions, were recorded.

The efficacy was evaluated 8 weeks after the end of treatment. Results　After treatment, the VSS score of all cases decreased

significantly compared to before treatment (P<0.05), the range of motion of the affected joint was significantly higher than before

the first treatment (P<0.05). The efficacy evaluation results showed that there were 19 cases of significant improvement, 8 cases

of effective treatment, and 3 cases of ineffective treatment, with a significant improvement rate of 63.3% and an effective rate of

90.0%. No adverse reactions such as blisters, infections, or hypertrophic scar formation were observed in the treatment area after

treatment. Conclusion　Laser treatment of finger contracture scar in children has obvious effect and less related complications,

which is worthy of clinical promotion.
