(2) Generally, rhinoplasty with hyaluronic acid can last for about 6- 12 months, and the duration is not very long. It is suggested that the second injection should be made within 4-8 months after the first injection of hyaluronic acid for rhinoplasty, otherwise it will return to its original appearance after absorption. Because hyaluronic acid is a component of human tissues, its absorption will be slower; Hyaluronic acid rhinoplasty can be injected twice and improved continuously. It can be seen that the disadvantages of injecting hyaluronic acid into rhinoplasty have also become potential advantages.
(3) Hyaluronic acid injection may have a certain effect on simple nasal root elevation, which can be absorbed after rhinoplasty, but for complex nasal contour modification, it is definitely not possible without autologous cartilage or prosthesis shaping.
