Rhinoplasty is a method of inserting fillers into the nose to improve its shape. Currently there are implants (silicone implants) and injectables (hyaluronic acid injections). Injectable rhinoplasty is a relatively new method of rhinoplasty. Although the development of rhinoplasty technology has reached a certain height, since hyaluronic acid injection has been used for rhinoplasty, rhinoplasty with hyaluronic acid has been challenged by the advantages of fast, painless, realistic shape and so on. The indications for hyaluronic acid rhinoplasty: low nose: low nasal bridge, lack of three-dimensional sense of the whole face. Saddle nose: The bridge of the nose and cartilage are mostly sunken, and the tip of the nose is upward, shaped like a saddle. Straight nose: the bridge of the nose is still high, but the shape is straight and lacks the cone feeling. Low-pitched nose: The tip of the nose is low and the highest point of the nose is located at the back of the nose. Low root nose: The root of the nose is low and the nose is short and out of proportion. Wavy nose: The dorsal axis of the nose is not complete and smooth. Horizontal nostrils: The nostrils are “eight” shaped and the nose is wide and flat. Humped nose: There is a hump on the back of the nose.
