Area of Science:

  • Aesthetic Medicine
  • Dermatology
  • Plastic Surgery

Background:

  • Midface aging characterized by nasolabial fold deepening and reduced malar highlight.
  • Sagging of midface soft tissues is a primary concern in facial aging.
  • Minimally invasive procedures are sought for effective facial rejuvenation.

Purpose of the Study:

  • To evaluate the efficacy and safety of 18-G polydioxanone (PDO) cog threads for midface lifting.
  • To assess patient satisfaction and objective outcomes of the PDO thread lift procedure.
  • To compare PDO thread lifting with conventional surgical methods for midface rejuvenation.

Main Methods:

  • 64 female patients (33-60 years) underwent midface thread lift using 18-G PDO cog threads.
  • Threads were inserted via stab incision, targeting deep medial fat pad and superficial muscular aponeurotic system.
  • Anchoring to the periosteum of the lateral orbit suspended soft tissues superiorly.
  • Outcomes assessed via subjective patient satisfaction and objective physician ratings.

Main Results:

  • No major complications reported; procedure averaged 15 minutes under local anesthesia.
  • Highest patient satisfaction (4.7/5.0) and objective scores (4.5/5.0) at 1 month post-procedure.
  • Satisfaction and objective scores showed a trend of decrease by 1 year (2.8/5.0 and 3.1/5.0, respectively).

Conclusions:

  • PDO cog threads provide a simpler, quicker, and less invasive alternative to traditional surgical midface lifts.
  • The procedure achieves satisfactory aesthetic results for a duration of at least 6 months.
  • This minimally invasive technique effectively addresses midface soft tissue sagging.
