Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Each year, millions of burn, trauma, or surgical patients worldwide suffer from scarring that severely affects their quality of life and social functioning. In order to prevent and treat diseases related to abnormal scar hyperplasia, clinicians and researchers have adopted various methods, such as scar grinding, surgical resection, drug injection in scar tissue, cryotherapy, laser and so on. However, these methods can not effectively inhibit the abnormal proliferation of scars and improve the adverse effects of existing scars on patients. To date, there is no accepted gold standard for the effective treatment and improvement of abnormal scar tissue.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Through a large number of literature review and preliminary experiments, we summarized and found the following problems: a. The latest research on prevention of scar formation by botulinum toxin type A is only aimed at surgical wounds from the wound type, and there is no research on the scar prevention effect of trauma wounds. b. From the point of view of the study site, there is no study on the effect of scar prevention only on the head, neck, chest and other parts of the body. c. For the research results of botulinum toxin type A in the prevention of scarring, the current research focuses on the effectiveness of botulinum toxin type A at a certain concentration, and does not compare the effects of botulinum toxin type A at various concentrations.Therefore, in order to explore the "optimal concentration" of botulinum toxin type A to prevent scar formation; To explore the effect of botulinum toxin A on scar prevention of traumatic wounds and surgical incisions. To explore the effect of botulinum toxin A on scar prevention in other parts of the body in addition to effective prevention of head, neck and chest scar, We intend to focus on the effectiveness and "optimal concentration" of botulinum toxin type A to prevent scarring, to determine the effect of this means on scar prevention, to provide new ideas for botul

Injection 1 U / 0.1ml BTXA

Botulinum toxin type A (BTXA) was injected into both sides of the knife edge immediately after operation, the injection volume was 1U/0.1ml per point, the interval between the injection points on the same side of the knife edge was 1cm, and the distance of each injection point from the knife edge was 0.5cm. It was injected only once immediately after operation.
