When parents see that their child has congenital malformations, they are particularly anxious to do it early, but they are worried about the physical condition of the child and the effect of anesthesia on the child, and they get different answers when they ask around. Indeed, different congenital malformations, depending on the degree of deformity, the development and urgency of the disease, the physical condition of the child, the level of professional anesthesia care for children and other differences, the timing of plastic surgery does vary. Moreover, the requirements for plastic surgeons are high because the organs and tissues of pediatric patients are delicate and require precise and meticulous surgical techniques. According to our research and observation, if the physical condition of the child allows, the condition requires, should do plastic surgery repair as early as possible, the reasons are: 1, early scar is small: research has proved that in the fetal period to do surgery, the fetal incision is not long scar. Generally speaking, the younger the age, the smaller the scar, the reason may be related to the gradual perfection of immunity in children, the greater the immunity, the stronger the reaction, scar formation is obvious. 2, the younger the child the less sensitive to pain: the neurological system of the child gradually develops after birth, the early sensory nerves are still in the primary stage of development, not sensitive to pain, and surgical wounds do not feel pain. When we performed a cleft lip on a newborn 7 days old, the child slept with a purr that night. In addition, in general, anesthesia has no effect on children’s brain and nerve development, especially the short anesthesia within 2 hours, almost no adverse effects. 3, early plastic surgery on children’s psychological development, family harmony: children within 3 years of age, the things in the hospital such as surgery and other basic will not leave a bad memory. As children grow up, they begin to have self-awareness, know that they exist and other children are not the same deformity, will produce a lack of confidence and other inferiority complex, may change the behavior of children, such as reluctance to participate in group activities, withdrawn, this abnormal psychology once formed, even if the deformity is later corrected, to correct the abnormal psychology is also more difficult. In addition, the parents of the child every day to see the child with deformities, the mood is more or less depressed, and even affect breastfeeding. Therefore, early plastic surgery so that the deformity is corrected, the child’s psychological health development is very important, but also to harmonize the family. 4, skin regeneration ability, good stretching: pediatric skin regeneration ability is strong, easy to stretch, help to pull the skin directly suture or reduce the trauma. For example, if the tumor on the body surface is removed at one time or in stages at an early stage, the surgical effect is significantly better than waiting for the child to grow up and then doing it again. 5. Strong compensatory ability: The ability of children to obtain motor function and compensatory function is obviously stronger than that of adults. When the surgical conditions are available, functional reconstruction should be performed as early as possible. Even if the anatomical reconstruction cannot be fully achieved, the compensatory function can be expected to be obtained. 6.It is not easy to form joint stiffness: while stiffness and limitation of motion may occur in adults with joints fixed for more than one month, children are less likely to develop joint stiffness and contracture. Children’s fixed joints can still be well rebuilt after the joint is unfixed. 7.Good correction effect: All tissues and organs of children are in infantile development stage and have the characteristic of easy change. At the right time, direct modification by surgery or correction by instruments can achieve good results. Therefore, only the physical condition of the child allows, the deformity affects the development and can be corrected, medical institutions have the appropriate medical anesthesia care and other children’s professional level, early plastic surgery to correct deformities is a wise choice.
