| ObjectiveThis study comprehensively evaluates the effectiveness of 3D facemask treatment for facial burn scars in terms of several indicators.To investigate the differences in the facemask treatment of scars by different TTH and to confirm the positive effect of 3D facemask treatment of scars in early stages.MethodsTo collect a total of 26 patients visited the burn rehabilitation department outpatient clinic for facial burns scars and were treated with 3D face masks from January 2017 to August 2022 at the First Affiliated Hospital of Anhui Medical University,the days required for all patients to heal from the acute phase of the wounds were collected and divided into the early healing group(TTH within 14-21days)and late healing group(TTH > 21 days)according to different TTH of the burn wounds.Basic patients information was collected including TBSA and percentage of the area of each burn depth(calculated according to this country’s nine-point method),nature of burn,the season of burn,TTH,and surgical history.The scars were assessed before the beginning of treatment and at multiple time points during treatment.VSS was used to assess the pigmentation,vascularity,pliability,and height of the scars.In addition,information was collected on patients’ satisfaction,treatment complications,facemasks wearing time,rates of excellence,and treatment costs.To compare the variations in scarred characteristics from pre-treatment to 9 months after treatment in the early healing group and the late healing group,and to compare the variability of scar characteristics between the two groups at the pre-treatment and the last post-treatment assessment.To compare the difference in scarred characteristics at multiple assessment points after treatment between the two groups.To compare the scar characteristics of the early healing group and the late healing group at the same time point after the burns and between the two-time points in each of these groups.Furthermore,intergroup differences in facemasks worn at each time point were analyzed for both groups and excellent rates were calculated for each group.ResultIn both groups,there were significant improvements in the total VSS scores(P<0.01)and each VSS subscore(P<0.01).These scar characteristics improved over time as the treatment progressed.Compared with the late healing group,the early healing group had more obvious effects on improving scar pigmentation(P<0.05)and vascularity(P<0.05)at similar assessment time points after burns.At the last assessment,there was a significant difference in total VSS scores between groups(P=0.009).There were significant differences in the scores of scar pigmentation,vascularity,pliability,and height(all P<0.01)in the early healing group at three groups different time points(pre-treatment versus 3 months,6 months,and 9 months after treatment).For the late healing group,there were significant differences in pigmentation and vascularity scores(all P< 0.01)at three groups different time points(pre-treatment versus 3 months,6 months,and 9 months after treatment).There were significant differences in pliability scores(all P<0.01)between the two time points(pre-treatment versus 6 months and 9 months after treatment)and significant differences in height scores(P<0.01)at the last time point(pre-treatment versus 9months after treatment).During the treatment period,the mean gradient value(SE)of the total VSS scores was 1.550(0.373)for the early healing group and 1.283(0.224)for the late healing group,respectively,indicating that patients in the early healing group had better overall outcomes over the same treatment time period.No complications were reported in this study.The excellent rate of patients in the early healing group was 66.67%,compared with 18.18% in the late healing group.Conclusion3D transparent face masks have excellent efficacy for the rehabilitation of facial scars caused by burns.It is important to minimize the TTH required for burn wounds that are clinically significant,and burn wounds with the TTH between 14-21 days can achieve better results and outcomes in the same course of treatment than wounds with TTH > 21 days.And it should be noted that this approach should be initiated in the early stages of scars development for prevention and treatment. |
