. 1. In recent years, rhinoplasty has been widely used. From the medical point of view, reinforcement material is the most ideal substitute for biological tissue at present, which is mainly used for vascular reconstruction in human organ transplantation. Expansive materials 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. 2. The operation depends on the doctor. The doctor is good at this operation, and the effect is good. There is also a prosthesis, and the selected prosthesis will have a good effect. At present, silica gel is commonly used, and the most expensive one is leather patch. Personally, I prefer silica gel, but it is more convenient to take it out. The swelling is not easy to transfer, and micropores can grow into blood vessels and nerves. Look at your financial conditions. The swelling is more expensive. Rhinoplasty generally takes 1-2 hours, and some complicated operations may take longer. Rhinoplasty can be performed under local anesthesia or general anesthesia, mainly depending on the scope of operation and respecting personal wishes. If the doctor chooses general anesthesia, you will fall asleep during the whole operation and feel nothing. If you choose local anesthesia, you will stay awake during the operation, but your nose and surrounding tissues will feel numb and insensitive, but occasionally you will feel a little uncomfortable. You just need to relax. 2. During the operation, the fascia on the back of the nasal bone is stripped, and then the nasal bone and cartilage are carved according to the medical aesthetics, the requirements of the operator and the skills of the doctor, or the carved nasal bracket is directly implanted to achieve the desired effect. Finally, sew the skin back to its original position.
