Abstract: Hypertrophic scar is the most common scar in the clinic. Due to its high incidence, high rate of recurrence, and difficulty of complete removal, it has always been a major problem in the department of burn and plastic surgery. In recent years, some scholars have found that botulinum toxin type A(BTX-A) can inhibit scar hyperplasia by reducing the tension around the wound, inhibiting the proliferation of fibroblasts, promoting their apoptosis, promoting the degradation of collagen fibers, reducing wound angiogenesis, reducing inflammation around the wound and other mechanisms. BTX-A has fewer adverse reactions and high safety. Additionally, its effect combined with triamcinolone acetonide and laser in treating scars is significant. Therefore, it has been widely used in the treatment of hypertrophic scars. In this paper, the research progress of BTX-A in the prevention and treatment of hypertrophic scar was reviewed in order to provide new ideas for the treatment of hypertrophic scar.
