Abstract:

Objective To evaluate the clinical effect of optimized intense pulsed light（OPT）combined with CO2 lattice laser on early facial and cervical scars intervention. Methods 96 patients with early facial and neck scars in our hospital from October 2020 to February 2022 were randomly divided into four groups with 24 cases in each group. The patients in the four groups were treated with silicon gel，CO2 lattice laser +silicon gel，OPT+ silicon gel，and OPT+CO2 lattice laser+ silicon gel respectively two weeks after operation. Except for the silicon gel，all patients were treated three times at one ⁃month intervals. Before treatment and one month after the third treatment，patients′ facial and neck scars were compared and analyzed by patient assessment scale（PSAS）， observer assessment scale（OSAS）and new Vancouver Scar Assessment Scale（VSS）；Record patient satisfaction and adverse reactions. Results The satisfaction rates of each group after treatment were 58.33%，83.33%，79.17%， and 95.83% ，respectively. The results of VSS，OSAS and PSAS after treatment showed statistical differences （P < 0.05），and the VSS score showed statistical significance in color，blood vessel and softness compared with before treatment（P < 0.05）. There were two cases of blisters and exudation during treatment without obvious abnor⁃ malities after timely intervention. Conclusion Optimized intense pulsed light（OPT）combined with low ⁃ energy CO2 lattice laser has satisfactory curative effect and fewer adverse reactions in the early intervention of facial and neck scars，warranting further research.
