Summary
Three-dimensional imaging assessed Contour threadlift results, showing midface soft tissue returned to baseline within 3 months. This advanced imaging offers superior accuracy for quantifying facial changes compared to traditional photography.
Area of Science:
- Medical Imaging
- Plastic Surgery
- Aesthetic Medicine
Background:
- Conventional 2D photography has limitations in visualizing 3D facial structures.
- Accurate measurement of esthetic outcomes is crucial in facial rejuvenation procedures.
Purpose of the Study:
- To evaluate the efficacy of Contour threadlift for midfacial rejuvenation using 3D imaging.
- To quantify soft tissue movement and changes in facial contour post-procedure.
Main Methods:
- Prospective study utilizing 3D imaging for pre- and post-operative facial visualization.
- Measurement of three-axis vector movement of facial soft tissue in millimeters.
- Inclusion of a control group to ensure image stability.
Main Results:
- A trend of midface soft tissue flattening was observed over 3 months, averaging 2.3 mm.
- Facial flattening returned to baseline levels by 90 days post-procedure.
- Control subjects showed minimal change (<0.2 mm) in the nasolabial region.
Conclusions:
- 3D imaging measurements indicated a return to baseline values for Contour threadlift patients after 3 months.
- 3D imaging provides enhanced accuracy for quantifying surgical contour changes compared to 2D methods.
- The application of 3D imaging is potentially valuable across various clinical settings.
