Early Changes in Facial Profile Following Structured Filler Rhinoplasty: An Anthropometric Analysis Using a 3-Dimensional Imaging System.

[BACKGROUND] Quantitative measurements are important for objective evaluation of postprocedural outcomes. Three-dimensional (3D) imaging is known as an objective, accurate, and reliable system for quantifying the soft tissue dimensions of the face.

[OBJECTIVE] To compare the preprocedural and acute postprocedural nasofrontal, nasofacial, nasolabial, and nasomental angles, early changes in the height and length of the nose, and nasal volume using a 3D surface imaging with a light-emitting diode.

[METHODS] The 3D imaging analysis of 40 Korean women who underwent structured nonsurgical rhinoplasty was conducted. The 3D assessment was performed before, immediately after, 1 day, and 2 weeks after filler rhinoplasty with a Morpheus 3D scanner (Morpheus Co., Seoul, Korea).

[RESULTS] There were significant early changes in facial profile following nonsurgical rhinoplasty with a hyaluronic acid filler. An average increase of 6.03° in the nasofrontal angle, an increase of 3.79° in the nasolabial angle, increase of 0.88° in the nasomental angle, and a reduction of 0.83° in the nasofacial angle was observed at 2 weeks of follow-up. Increment in nasal volume and nose height was also found after 2 weeks. Side effects, such as hematoma, nodules, and skin necrosis, were not observed.

[CONCLUSION] The 3D surface imaging quantitatively demonstrated the early changes in facial profile after structured filler rhinoplasty. The study results describe significant acute spatial changes in nose shape following treatment.
