The preliminary design of micro-plastic rhinoplasty is very important, and the following principles should be followed: symmetry, balance, proportion coordination, golden triangle and golden section law, beautiful lines or curves, harmony and beauty. In addition, we should also pay attention to the surgical principles such as concealed incision, aseptic operation, gentle operation and less trauma. In addition, we should also take care of the subject's aesthetic psychology and psychological endurance.

In addition, for people with swept forehead, low eyebrow arch, low middle face and backward chin, micro-plastic rhinoplasty alone is often not enough to make their faces beautiful. Therefore, we can perform eyebrow augmentation, chin augmentation or other plastic surgery at the same time or successively according to the patient's condition, which will make the face more symmetrical and harmonious.
