Hello, it depends on how you choose to do rhinoplasty. If it is injection rhinoplasty, the potential harm will be great. With the blood circulation, the injected substance may be free, which is dangerous! The safest thing now is prosthetic rhinoplasty. If you put the whole silicone prosthesis in, it won't do any harm, but if you don't like it in the future, you can take it out without any harm.
