Abstract:
Objective:To compare the clinical effects of the two design schemes of heart-shaped incision and "Mercedes-Benz incision" (three-leaf method) in umbilicoplasty.Methods:A retrospective analysis was performed for the clinical data of patients who underwent umbilicoplasty during abdominoplasty admitted to the Body Contouring & Fat Grafting Center, Plastic Surgery Hospital, Chinese Academy of Medical Sciences, from November 2019 to September 2022. During the umbilicalplasty operation, different patients were treated with either a heart-shaped incision or a "Mercedes-Benz incision" three-flap method. The umbilical cord for infection, hematoma and other complications were observed after surgery; a 5-point Likert scale was used to evaluate the aesthetic effect of the new umbilicus 6 months after surgery(3-15 points, the higher the score, the better the aesthetic effect); the Vancouver scar scale (VSS) was used to score the scar condition 6 months after surgery (0-18 points, the higher the score, the better the scar condition). Postoperatively, patients were surveyed on umbilical shape satisfaction, which was divided into three levels: dissatisfied, relatively satisfied, and very satisfied. Normally distributed measurement data were expressed as Mean±SD, and independent samples t-test was used for comparison between two groups. P<0.05 was considered as a statistically significant difference. Results:A total of 35 patients were enrolled, all of whom were female. Among them, 19 cases underwent heart-shaped incision, and 16 cases underwent umbilicoplasty using "Mercedes-Benz incision". The ages of the two groups were (32.3±2.7) years old and (33.7±2.3) years old respectively. At the 6-month follow-up after surgery, the total aesthetic effect score of the umbilical cord in the heart-shaped incision group was higher than that in the "Mercedes-Benz incision" group [(13.3±0.7) points vs. (12.7±0.5) points, P<0.05]. The VSS score of the heart-shaped incision group was lower than that of the "Mercedes-Benz incision" group [(2.6±0.8) points vs. (3.4±0.9) points, P<0.05]. The results of the satisfaction survey after umbilicoplasty showed that in the heart-shaped incision group, 3 cases were relatively satisfied and 16 cases were very satisfied; in the "Mercedes-Benz incision" group, 2 cases were relatively satisfied and 14 cases were very satisfied. Conclusion:Compared with the classic "Mercedes-Benz incision", the heart-shaped incision design can obtain a better-shaped, more natural new umbilicus and a more invisible scar after umbilicoplasty.
