Abstract
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. 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. 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). 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. 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.
