Asymmetrical thread lifting effectively corrected facial rotation in 89% of patients, improving symmetry and satisfaction. Further research is needed to validate these promising results for facial asymmetry treatment.
Area of Science:
- Aesthetic Medicine
- Dermatology
- Plastic Surgery
Background:
- Facial asymmetry, especially rotational, significantly affects facial harmony and perceived attractiveness.
- Conventional rejuvenation methods often use symmetrical approaches, potentially overlooking rotational patterns.
- This study explores asymmetrical thread lifting for correcting facial rotation.
Purpose of the Study:
- To assess the effectiveness of unilateral thread placement in the nasolabial fold for correcting facial rotational asymmetry.
- To establish a standardized method for treating clockwise facial rotation patterns.
Main Methods:
- Forty-five patients with facial rotation underwent asymmetrical insertion of JETEMA threads using a reverse technique.
- Threads were placed unilaterally in the nasolabial fold area.
- Facial rotation was assessed using standardized photography and a 4-point Facial Rotation Grading Scale (FRGS) pre-treatment and at 6-month follow-up.
Main Results:
- 89% of patients showed improvement in facial symmetry at 6 months, per the FRGS.
- Severe rotation cases improved to mild, and most moderate cases improved to mild.
- Average patient satisfaction was 8.3/10, though results require cautious interpretation due to assessment limitations.
Conclusions:
- Standardized unilateral thread lifting with a reverse technique shows potential as a minimally invasive option for facial rotational asymmetry.
- Further studies are necessary, utilizing validated assessment tools and objective measurements, due to methodological limitations like a non-validated scale and short follow-up.
