Face collapse, don't think too much. Simple rhinoplasty won't. Facial stiffness is mostly caused by overdose. Too many times of rhinoplasty may lead to serious problems in nose shape.

Rhinoplasty materials can be roughly divided into biological materials and non-biological materials. Biological materials: autogenous cartilage (costal cartilage, nasal septum cartilage, ear cartilage) allogenic bone; Abiotic materials: prosthesis (silica gel and expansion).

The biggest feature of biomaterials is that they will eventually merge with their own tissues and become a part of their own tissues; If you are worried that taking your own cartilage will leave scars and other problems, you can choose allogenic bone; Allograft bone will be put into use after multiple screening and processes, and there is no problem in safety.

I think you should choose bulking. The main advantage of expansion is that the expanded material is opaque; Easy molding and good histocompatibility; Microporous structure allows tissues to grow in, so it is not easy to slide and has good stability. In contrast, there must be shortcomings, such as hard hand feeling and no absorption after operation; Compared with silicone prosthesis, it is difficult to take out; The probability of postoperative prosthesis infection is high; The risk of prosthesis leakage is easy to occur in the later stage; It does not form a capsule, adheres to the surrounding tissues, easily exposes the prosthesis, and has an unnatural appearance.

Silica gel, with strong plasticity, widely available materials, is relatively close to the people. The performance is relatively stable, without absorption, and it can be stored in the organization for a long time. It has enough hardness to support the tissue structure and is easy to take out. Non-toxic, harmless, high and low temperature resistant, corrosion resistant, non-carcinogenic, non-teratogenic and good histocompatibility. Because silica gel prosthesis is composed of silica gel molecules, it will stimulate tissue cells to a certain extent, so it is not suitable for people with thin skin at the back of nose, which will lead to thinning of subcutaneous tissue, dilation of subcutaneous capillaries, necessary skin will be red and shiny, and the tip of nose will become sharp, which will easily lead to prosthesis. At present, some doctors still use the L-shaped prosthesis, but this is the least recommended choice, mainly because the L-shaped prosthesis will have an impact on the skin at the tip of the nose. After a long time, the skin will become thinner and thinner, and eventually it will protrude out of the skin, resulting in the need for long-term removal or repair. Most doctors choose willow prosthesis for rhinoplasty.

I briefly told you about the choice of materials. If you want to have surgery, you must choose a regular plastic surgery hospital, be responsible for your own safety, and then find a doctor with rich clinical experience, so as to better ensure the postoperative effect.
