Multi-layered thread lifting using varied thread thicknesses in deeper and shallower subcutaneous fat layers enhances initial lifting and sustainability. This technique improved patient satisfaction and maintained high aesthetic results for at least six months.
Area of Science:
- Aesthetic Medicine
- Dermatology
- Plastic Surgery
Background:
- Thread lifting efficacy varies with thread insertion depth.
- Optimizing thread placement is crucial for maximizing lifting effects and longevity.
Purpose of the Study:
- To evaluate a multi-layered thread lifting technique using varied thread thicknesses.
- To maximize aesthetic lifting effects and patient satisfaction.
Main Methods:
- Thread lifting performed on 43 patients with thicker threads in deeper subcutaneous fat and thinner threads in shallower layers.
- Ultrasonography used to measure thread depth post-procedure.
- Patient satisfaction and Global Aesthetic Improvement Scale (GAIS) evaluated.
Main Results:
- Significant increase in patient satisfaction immediately post-procedure.
- High GAIS scores were sustained for 6 months, indicating lasting aesthetic improvement.
- Multi-layered insertion proved more effective than single-layer insertion.
Conclusions:
- A multi-layered thread lifting approach with varied thread thicknesses is effective for enhancing aesthetic outcomes.
- This technique leads to high patient satisfaction and sustained results.
- Optimizing thread placement in multiple subcutaneous layers improves thread lifting efficacy.
