Most small wound depressions in children are able to grow flat, but larger wounds, which tend to be more of a scar tissue repair, do not fully return to their original condition. If a child has an uneven skin edge or a small amount of subcutaneous tissue loss after trauma, the wound will appear to be mildly depressed after debridement and suturing. Generally after healing, with the repair of scar tissue, the depression will gradually rise to normal. If the child has a large area of defect after trauma, there is a large area of depression after serious injury and suturing, it will be difficult to return to normal during the development process, and there may be a permanent depression, which affects the aesthetics, but generally has little effect on the function. If the child is keloid, the wound can form a large scar after healing, obviously raised in the skin will also affect the beauty, can also go to the cosmetic department for further treatment.
