Clinical Observation On Early Intervention Of Facial And Neck Scar With Optimal Pulse Technology Combined With The Low-energy CO₂ Lattice Laser

Objective:To evaluate the clinical effect of early scar intervention on the fa ce and neck by combining optimal pulse technology（OPT）with the low-energ y CO₂lattice laser.Methods:96 patients with early facial and neck scar who visited our hospital from October 2020 to February 2022 were randomly selected and divided into four groups A,B,C,and D,with 24 patients in each group.The patients in the four groups were given silicone gel application（group A）,CO₂lattice laser+silicone gel application（group B）,OPT+silicone gel application（group C）,and OPT+CO₂lattice laser+silicone gel application（group D）two weeks after surgery.All treatments except silicone gel were given 3 times with 1 monthly interval each time.Before treatment and 1 month after the third treatment,the patients were compared and analyzed with the new Vancouver Scar Scale（VSS）,Patient Scar Assessment Scale（PSAS）and Observer Scar Assessment Scale（OSAS）,respectively,and their satisfaction and adverse reactions were recorded.Results:1.After scar treatment,the four groups of patients were compared between VSS,OSAS,and PSAS,and the differences were statistically significant.Among them,groups B and D had significantly lower VSS,OSAS,and PSAS scores,group C had significantly lower VSS and OSAS scores than group A;Compared with groups B and C,group D had significantly lower VSS,OSAS and PSAS scores.2.Among the indexes of VSS,there were statistically significant differences among the four groups of patients after treatment in terms of color,vascularity,and softness.Among them,groups B,C,and D had significantly lower scores compared with group A.Group C had lower scores in color and vascular distribution and higher scores in softness than group B.Group D had significantly lower scores in softness compared with group C and in color and vascular distribution compared with group B.3.The satisfaction rates of each group after treatment were 58.33%,83.33%,79.17%,and95.83%.There were two cases of blistering and exudation in the treatment,and there was no significant abnormality after the timely intervention.Conclusion:The combination of the optimal pulse technology and low-energy CO₂lattice laser improved significantly in terms of color,vascularity,and softness of facial and neck scar,and the combined treatment could significantly shorten the immature phase of the scar and accelerate the scar stabilization,which may provide a reference value for clinical scar treatment.
