Abstract：Objective To evaluate the effect of hyaluronic acid injection rhinoplasty on nasal contour and overall aesthetic ap-pearance. Methods 3D scan data before and after hyaluronic acid injection were collected in 14 patients who underwent augmentation rhinoplasty. 3D reconstruction software was used to measure nasal length, nasal height, nasal tip height, nasal frontal angle and nasolabial angle preoperative and postoperative. The sex, age and injection dose were recorded. The standard photographs were taken and the compli-cations were recorded. Results The injection dose for each of the14 patients was (0.7 ± 0.2) ml. Nasal length, nasal height and the nasal tip height were increased after rhinoplasty, and the nasal frontal angle was smaller (P<0.05). The nasal width and nasolabial angle had no significant difference preoperative and postoperative (P>0.05). Patients had no adverse reactions. Conclusion Injection rhinoplasty can significantly improve the flatness of the nasal root. 3D technology is stereoscopic, and offers the additional advantages of convenience and accuracy, as well as being intuitive. It is an effective tool toquantitatively assessthe changes of the nose shape.
