Clinical application of absorbable collagen thread and cosmetic suture technique in emergency treatment of children's facial trauma.

Aim: To explore the effect of absorbable collagen thread and cosmetic suture technique on scar inhibition after emergency facial trauma in children, and to explore the application value of absorbable collagen thread in emergency facial trauma.

Methods: Children who received emergency treatment of facial trauma in plastic surgery department from January 2021 to January 2022 were analysed retrospectively, and were divided into absorbable collagen thread group and non-absorbable nylon thread group. The general data, scar appearance and local symptoms of the two groups were analysed, and the scar appearance was scored by scar beauty rating scale and non-inferiority test was analysed statistically.

Results: A total of 632 children with facial trauma were included in this study, including 458 patients with absorbable collagen thread and 174 patients with non-absorbable nylon thread. The SCAR score of the absorbable collagen thread group (3.03 ± 1.57) was similar to that of the non-absorbable nylon thread group (2.98 ± 2.39) (95% confidence interval), and the final scar outcome score was not statistically different (P > 0.05). All families of the patients were satisfied with the results of the procedure, 95% very satisfied.

Conclusion: The use of absorbable collagen thread and cosmetic suture technique to treat the wounds of children with facial emergency trauma, resulted in good wound healing, little scar expansion, low incidence of erythema and pigment abnormality, no obvious surgical trace, and no scar hypertrophy or atrophy. The overall impression was good, the pain of stitch removal was avoided for children's patients, and the satisfaction of family members was high. Cosmetic suture technique with absorbable sutures is worthy of clinical application.
