At present, rhinoplasty is simply to implant a prosthesis at the back of the nose to improve the height of the bridge of the nose. However, nasal synthesis is different. It not only improves the plastic height and shape of nose, but also improves the curve of individual face. It is suitable for people who have two or more problems in the height of the bridge of the nose, the shape of the tip of the nose, the width of the alar and the shape of the nostril, and can completely solve the nasal defects after anatomical adjustment.
