Abstract：Objective To evaluate the application value of ultra-tension-relieving suture in incision repair after excision of benign skin tumors.Methods Clinical data of 54 patients who underwent excision of benign skin tumors and completed follow-up in the outpatient department of Beijing Anzhen Hospital,Capital Medical University from September 2023 to December 2024 were retrospectively analyzed.According to the suture method after skin tumor resection,patients were divided into control group(25 cases)receiving traditional tension-relieving suture and observation group(29 cases)receiving ultra-tension-relieving suture.Incision healing at 2 weeks after operation,incidence of complications,and scar appearance and texture at 6 months after operation were compared between the two groups.The Vancouver Scar Scale(VSS),Patient Scar Assessment Scale(PSAS)and Observer Scar Assessment Scale(OSAS)were used for scoring.Results There was no significant difference in delayed healing rate between the two groups(P=0.463).The incidence of infection and hematoma in the observation group was lower than that in the control group,and the pigmentation rate was similar to that in the control group,but the differences were not statistically significant(all P＞0.05).In each subscore of VSS,the scores of pigmentation,vascularity,pliability and total score in the observation group were significantly lower than those in the control group[1.0(1.0,1.0)vs 2.0(1.0,2.0),1.0(0.0,1.0)vs 1.0(1.0,2.0),1.0(1.0,1.0)vs 2.0(1.0,2.0),and(3.3±1.4)vs(5.4±2.5)](all P＜0.05).The scores of color,pliability,patient satisfaction,pain,itching and overall impression in PSAS of the observation group were significantly lower than those of the control group,and the scores of vascularity,pigmentation,pliability,surface roughness,area and overall impression in OSAS of the observation group were significantly lower than those of the control group(all P＜0.05).Conclusion Ultra-tension-relieving suture can effectively disperse incision tension,reduce scar formation and improve postoperative aesthetic effect.
