The nose is the only three-dimensional organ of the human face, and it is a key factor in shaping the temperament. Having a straight nose can greatly enhance the beauty of one’s face, and is therefore the wish of many beauty seekers. Nowadays, there are two main methods of rhinoplasty, prosthesis placement and injection rhinoplasty, so what are the advantages and disadvantages of the two methods, and how to choose? In this article, we are going to explain the advantages and disadvantages of the two methods, and how to choose? Injection rhinoplasty] Injection rhinoplasty is an emerging way of rhinoplasty in recent years, and its mechanism, as the name suggests, is to inject different materials into the back of the nose through a syringe at a specific level to achieve the effect of rhinoplasty. However, it should be noted that China’s cosmetic medical market is not yet standardized enough, and is filled with a wide variety of injectables that are exaggerated by various businesses, many of which are even harmful. Many candidates who come to Nine Hospitals for treatment are requested to take out the injections after the failure of rhinoplasty, and once injected, the injections can’t be taken out cleanly, so going to regular hospitals for injections is the first thing for candidates. At present, through clinical testing, the only injectable rhinoplasty injection that is authorized to be carried out in the Nine Hospitals is Ruilan (hyaluronic acid), and there are several other materials that are in the stage of clinical testing, and it is estimated that they will be adopted soon. Injectable rhinoplasty is suitable for those who have a certain foundation of the nose and need to add to it, as well as those who are not yet able to undergo surgery and would like to observe the results after rhinoplasty. It should be noted that hyaluronic acid can be maintained for ten months after injection. After ten months, the injected hyaluronic acid will degrade on its own, and the nose will return to the way it was before injection. Compared with injection rhinoplasty, the advantages of rhinoplasty with prosthesis are as follows: firstly, it does not require high requirements for patients’ basic conditions, and patients with very low and flat nose bridge can also undergo it; secondly, it maintains a long period of time, and as long as no rejection reaction occurs, the prosthesis can be placed in the body for a lifetime; thirdly, rhinoplasty with prosthesis can be carried out at the same time with cartilage transplantation and tip reshaping and other comprehensive rhinoplasty, so as to make the improvement of nose shape more obvious. Thirdly, rhinoplasty can often be performed in conjunction with comprehensive rhinoplasty such as cartilage grafting and tip reshaping, making the nose shape more obvious. The disadvantage of rhinoplasty with implants is that there is a certain period of recovery after surgical treatment, usually 1 to 2 weeks for obvious swelling and 1 to 2 months for natural recovery. Moreover, due to the different physique of individuals, a very small proportion of patients will have rejection reaction after placing the prosthesis and need to remove the prosthesis.
