Abstract：Objective To evaluate the effect of improved modified buried vertical mattress sutures(MBVMS)technique in the healing and scar formation of chin trauma.Methods A total of 90 patients with chin trauma in Emergency Department of Plastic Surgery,Beijing Anzhen Hospital,Capital Medical University from February 2017 to June 2023 were selected.According to the random number table method,they were divided into the observation group(n=45)and the control group(n=45).After cleaning the wounds,the patients in the observation group were closed with improved MBVMS,and the patients in the control group were closed with conventional cosmetic suture.The patients in the two groups were all treated with silicone gel scab-removing ointment for about 3 months after removing the stitches.The wound healing of patients in the two groups was observed after 7 d of suture removal.The Vancouver Scar Scale(VSS),Visual Analogue Scale(VAS),Observer Scar Assessment Scale(OSAS),and Patient Scar Assessment Scale(PSAS)were used to evaluate the scar formation of patients in the two groups at 3 and 6 months after operation.Results Stitches were removed 7 d after operation.In the observation group,44 cases(97.8％)had grade A wound healing and 1 case(2.2％)had grade B wound healing.The wounds of the control group were all grade A healing.There was no statistically significant difference in the proportion of grade A healing between the observation group and the control group[97.8％(44/45)vs 100.0％(45/45)](P＞0.05).At 3 and 6 months after operation,the VSS,VAS,OSAS and PSAS scores of the observation group were lower than those of the control group(all P＜0.05).Conclusion The application of improved MBVMS technology in patients with chin trauma can not only ensure the safe wound healing,but also effectively improve the character of scar after wound healing,reduce postoperative scar hyperplasia,and achieve good cosmetic results.
