When a baby is burned, parents are most concerned about scarring in the future. However, deeper wounds or infections of the wounds during the treatment process will inevitably leave scarring. After the trauma heals, if the skin is red, swollen, higher than the skin surface and itchy, these are all post-burn proliferative scars, and if the baby’s limb dysfunction has not yet appeared, the following methods can be used first: first use topical products to control the pain and itch, and at the same time, can inhibit scar proliferation and promote scar maturation. For example, silicone diaphragms can be applied externally or silicone gel can be applied externally, and medications such as Conrad and cumene cream can also be used externally. Compression can also be applied with an elastic sleeve or elastic bandage. This type of scar takes a long time to mature, ranging from 2-3 years for short ones to more than 10 years for long ones. As long as the scar does not cause dysfunction, it is perfectly acceptable to wait until the scar is stable before undergoing plastic surgery. The criteria for a stable scar are: no pain, flattening, whitening, and softening. When the child is more than 10 years old, preferably at the age of 16 or 7, plastic surgery can be performed according to the situation at that time. If the scar is still above the skin surface and the area is large, dilator flap repair surgery can be performed. If the area is smaller, excision and suturing or local flap transfer surgery can be performed. If the scar is flat, non-surgical treatment such as laser can be used directly to fade the scar, but not to eliminate it completely. If the proliferation of any stage of the scar causes dysfunction of the baby’s limbs or five senses, the baby must be seen by the hospital’s plastic surgery department as soon as possible to solve the functional problems early.
