General Hospital of Hubei Military Region: 1. Surgical treatment of scar: scar is controlled by surgery, and it should be used when the scar is in a stable state (generally scar has been formed for more than half a year) and its shape is wide, thick or indecent. Surgical methods include scar excision, re-sewing, Z-shaped or W-shaped scar repair, dermabrasion and so on. If the scar is too big, you can consider removing it by stages or placing a tissue expander for a period of time before removing the scar.

2. Laser treatment of scars: it has four characteristics: strong monochromaticity, strong directionality, high energy density and good coherence. It is a new medical technology different from other medical technologies. There are many kinds of lasers used in the medical field, but there are not many lasers that can be used to treat scars at present. It mainly uses unique techniques such as cauterization, vaporization, cutting, curing and defocusing to directly change the output power of laser or adjust the focused laser beam to treat different scars with different characteristics.
