P115 : Facial profile alteration following filler rhinoplasty: analysis by overlay of before-and-after 3D images

Background: The nose is the most prominent feature of the face being located in the center. Nose augmentation, either through surgery or filler injection is a popular procedure in East Asian countries but the assessment of its outcome remains highly subjective. 3D imaging has been developed to enable more precise evaluation of the changes of the nose after rhinoplasty. Objectives: In this study, we have used a 3D imaging system (Morpheus 3D scanner) to identify the anthropometric changes of the face following filler rhinoplasty. Methods: A total of 40 patients who underwent filler rhinoplasty (20 patients with a cannula and 20 patients with needle) were included in the study. 3D images were obtained before, immediately after, 1 day after and 2 weeks after the procedure and superimposed using the common facial landmarks. Results: The volume increase of the nose at 2 weeks was 3.12 ml per 1ml of filler injected. The change in sellion depth was 3.65 mm per ml of filler material. There were also significant changes in the nasofrontal, nasofacial, nasolabial and the nasomental angles following filler rhinoplasty. Differences in the measurements between the cannula and the needle group were also identified. Conclusion: Based on the results of our study, we suggest the 3D imaging system to be a reliable and promising tool for quantifying the changes in soft tissue dimension of the face.
