Abstract:
Objective: This is a 24-month prospective follow up study that aims to determine the efficacy of mid-face lifting and lower jawline contouring in Asian patients with poly lactic-co-glycolic acid (PLGA) sutures. Method: Ten healthy volunteers received three pairs of 8-cones bidirectional cones sutures in the mid-face. One out of ten volunteers lost to follow-up at 12 months, the other patients followed up to 24 months. An "improvement" refers to at least a "onegrade change" in the facial laxity rating scale (FLRS) was the primary outcome measure. Other assessment parameters include the severity of the nasolabial fold, NLF (WSRS). Secondary outcome measures are the self-satisfaction rating scale (SSRS) and global aesthetic improvement scale (GAIS) graded by participant, completed at each interval follow-up. Data collected were analysed by a statistician and computer software program using paired t-test, and their T-test effect size using Cohen's d measure. Results: There was an "improvement" in mid-face almost immediately and linear progressive trend up to at least 12 months following intervention without deterioration at 24 months. Such "improvement" was clinically significant (p<0.05), and the differences were large (Cohen's d >0.8) between before and after treatment at each follow-up interval over the follow-up period. Contour improvement for the lower face followed a similar trend, except a delay in the observable differences at three months (Cohen's d =0.29, 0.8 at 6 weeks and 3 months). The difference in the improved level of satisfaction was clinically significant (p<0.05) from 6 weeks up to 24 months, which peaked between 12 and 18 months based on both GAIS and SSRS ratings. Conclusion: Mid-facing lifting in Asian patients with mild-to-moderate laxity is safe and effective with PLGA bidirectional cones sutures, with concurrent improvement in the lower face contour and an elevated patients' satisfaction over the 24-month follow-up period.
