Traumatic injuries of different parts and degrees are common in life and work, and many small wounds are not taken seriously by people and are mostly treated by themselves. With the continuous improvement of people’s living standard, more patients with skin abrasions, burns and cuts choose to go to hospitals for formal treatment, which shortens the healing time, improves the treatment effect and reduces the occurrence of infection. At the same time, with the continuous development of clinical medicine, general surgical suture technology has not been able to meet the needs of some patients with trauma on the exposed parts of the head, face, arms, etc. Due to the wide scar left after the trauma healing, many patients need secondary surgery to remove the scar, which not only increases the time and cost of expenditure, causing negative impact on the heart, but also because the best treatment time is missed, the effect is mostly inferior to emergency plastic treatment. Plastic surgery has conducted more theoretical and technical exploration in the treatment of body surface trauma, and emergency plastic surgery provides a new option for more and more demanding trauma patients. The application of plastic surgery’s tension-free suturing techniques and fine manipulation techniques at the first sign of trauma significantly reduces scar production, maximizes the original shape of the skin, reduces the negative psychological impact of trauma, and meets the higher requirements of patients.
