Plastic surgery can be divided into five categories: 1. Burn plastic surgery can treat and reconstruct the appearance or dysfunction caused by scars and deformities after burns. 2. Treatment and reconstruction of congenital facial deformities such as facial trauma, facial fracture and cleft lip and palate in craniomaxillofacial surgery. 3. Hand surgery hand trauma, congenital malformation, limb reattachment, micro-flap transplantation, etc. 4.

Rhinoplasty: the maximum breast enhancement can only be 4 mm: the maximum increase on each side is 330CC. Double eyelid incision: the maximum incision can only be 10 mm. Some people think that if the plastic surgery is not done well once, it can be modified until it is satisfactory. This idea is too naive.
