To analyze the aesthetic effect of plastic surgery in repairing facial soft tissue injury. Methods From January 2022 to March 2023, 60 patients with facial soft tissue injury who underwent plastic surgery in Beijing Badachu Second Medical Cosmetology Hospital were selected. According to the time of repair, they were divided into control group (receiving treatment first) and observation group (receiving treatment later), with 30 patients in each group. The control group was given routine repair, and the observation group was given plastic surgery. The surgical indexes, incision healing degree, scar recovery and aesthetic satisfaction were compared between the two groups. Results The operation time of the observation group was shorter than that of the control group, and the intraoperative blood loss was less than that of the control group (P <0.05). The grade A healing rate of incision in the observation group was 63.33%, which was higher than 33.33% in the control group (P <0.05). The proportion of grade I scar in the observation group was 56.67%, which was higher than 36.67% in the control group (P <0.05). The aesthetic satisfaction of the observation group was 93.33%, which was higher than 70.00% of the control group (P <0.05). Conclusion Patients with facial soft tissue injury undergoing plastic surgery can effectively improve the wound healing effect, and the repair effect is good. Meanwhile, the operation time and intraoperative blood loss are less than those of the control group, which is worthy of clinical application.
