Objective: To investigate the clinical efficacy of plastic and cosmetic suture techniques in patients with specific types of facial trauma, while adhering to the primary principle of emergency care. Methods: A total of 60 patients with facial trauma admitted to the emergency department of our hospital between December 2024 and May 2026 were selected and randomly divided into two groups using a random number table. After completing vital sign assessment, hemostasis, and deep tissue exploration, all patients underwent either conventional debridement and suturing in the control group or plastic and cosmetic suture techniques in the observation group. Baseline characteristics of the wounds in both groups—including location, depth, degree of contamination, and time from injury to presentation—were matched. The outcomes were compared between the two groups using the Vancouver Scar Scale (VSS), the Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS), the Patient-Observer Scar Assessment Scale (POSAS), and the SCAR-Q. Results: At 3 months postoperatively, the total VSS score and all component scores in the observation group were significantly lower than those in the control group (P<0.05); the SAS and SDS scores in the observation group were also significantly lower than those in the control group (P<0.05); the POSAS scores for both patients and observers in the observation group were significantly lower than those in the control group (P<0.05); however, the SCAR-Q score in the observation group was significantly higher than that in the control group (P<0.05). Conclusion: Under strict adherence to patient selection criteria and ensured medical safety in emergency settings, plastic and cosmetic suture techniques can effectively reduce postoperative scar formation in patients with specific facial wounds, improve patients" psychological well-being, and enhance their subjective perception of scars as well as their psychosocial adaptive capacity.
