At present, the commonly used materials of nose pad are silicone rubber, expander and autologous cartilage. The following is a detailed introduction: rhinoplasty: rhinoplasty was used for vascular reconstruction of human organ transplantation before, and later for plastic surgery. The materials used for rhinoplasty have the best compatibility with human body, and are non-toxic, non-carcinogenic and non-allergic, and do not need to be replaced for life. The texture and feel of the swelling material are very close to normal nasal tissue. After rhinoplasty, it is beautiful and natural, and it is not easy to detect. It has a special microporous structure, in which tissue cells and blood vessels can grow to form tissue connection, which is as perfect as autologous tissue. The expanded rhinoplasty material does not move or deform, and it is integrated with the nasal tissue, and it is even more impossible to wear out the skin. It does not have the "transparency" of silicone, and it is light in weight and does not feel like falling.

Rhinoplasty is suitable for 1. Subjectively, rhinoplasty is a beauty seeker who asks for the beauty of the nose. 2, the nose is low. 3. The nose visual effect caused by bad eyes, cheekbones and forehead is poor. 4, rhinoplasty loser.

Dilators and silicone materials can be carried for life, and silicone rhinoplasty is also a commonly used rhinoplasty method at present. Autologous cartilage is the most ideal material for rhinoplasty at present, including ear cartilage, nasal septum and costal cartilage. Ear cartilage and nasal septum cartilage can only be used for nasal tip plastic surgery because of limited bone sources. Ear cartilage raises the tip of the nose and increases the curvature of the tip of the nose. Nasal septal cartilage is used to lift and lengthen nasal columella at the tip of nose; Costal cartilage can improve the bridge of nose and tip of nose at the same time because of its rich bone source.

Autologous cartilage rhinoplasty is more suitable for patients with mild saddle nose or low nose. Of course, after implantation, it has no stimulation to tissues, can maintain the original volume and cell morphology for a long time, and is easy to cut into the required size and shape. Therefore, after rhinoplasty, the appearance is natural and realistic.
