Autologous fat injection rhinoplasty has certain advantages. Because autologous fat belongs to our own tissue, it generally does not produce dissimilarity, and can avoid the concerns related to prosthesis, and the survived fat is permanent, compared with hyaluronic acid, it is more cost-effective. However, there are two sides to everything, after autologous fat injection for rhinoplasty, the following abnormal phenomena may occur: 1, widening of the bridge of the nose: it is more common, and it is related to the improper injection site; 2, the height of the bridge of the nose is insufficient in the long term: because the fat is partially absorbed, the candidate may need to take several supplemental injections, and for the candidate with a lower dorsum of the nose, the effect of rhinoplasty with a prosthetic body is better; 3, the effect of the plastic surgery is poor: due to the morphology of the fat characteristics, it may be far less effective than the shaping effect of hyaluronic acid, prosthesis and autologous cartilage. Therefore, when choosing autologous fat rhinoplasty, candidates need to choose professional and experienced doctors, and if the aesthetic level is higher, the result will be better. After an interview, candidates need to choose the most suitable surgical plan with their personal circumstances, which can guarantee the safety of the surgery as well as obtaining good surgical results.
