There are many methods of rhinoplasty, such as injection rhinoplasty, augmentation rhinoplasty with expander and augmentation rhinoplasty with silicone prosthesis. At present, the most widely used method is augmentation rhinoplasty with expander. From the medical point of view, swelling material is an ideal substitute for biological tissue at present, which has the best compatibility with human body and is non-toxic and non-allergic. Before rhinoplasty, we should make a personalized rhinoplasty plan according to the facial features and personal temperament of the beauty seeker, and carve the prosthetic material during the operation, so that the prosthetic material can match the nasal dorsal bone accurately and firmly, and achieve better results.
