Polydioxanone (PDO) Thread Lift for Face: A Novel Anatomical Approach.

Area of Science:

• Plastic Surgery
• Aesthetic Medicine
• Regenerative Medicine

Background:

• Barbed thread facelifts are popular but lack standardized optimal placement strategies.
• Current cannula-driven methods often lack firm anchors and underutilize thread barbs, impacting clinical effectiveness.

Purpose of the Study:

• To propose and evaluate a novel technique for facial rejuvenation using molded polydioxanone (PDO) threads.
• To enhance midface and lower face lifting by utilizing specific anatomical structures and ensuring full barb engagement.

Main Methods:

• A bi-directional threading technique using molded PDO threads.
• Midface lift: PDO threads attach to zygomatico-cutaneous ligaments (ZCL) and anchor to the superficial layer of the deep temporal fascia (SDTF).
• Lower face lift: Threads engage the buccal fat complex and hitch at the sideburn region, utilizing the platysma auricular ligament for jowling improvement.

Main Results:

• The novel PDO thread technique was performed on 83 patients with minimal complications.
• Effective mid and lower face elevation was achieved with favorable, natural-looking aesthetic outcomes.
• High patient satisfaction was reported, attributed to the engagement of ZCL and buccal fat, solid anchoring, and full barb utilization.

Conclusions:

• The proposed PDO thread facelift technique offers an effective method for facial rejuvenation, particularly for mid and lower face lifting.
• This technique leverages established plastic surgery principles for enhanced aesthetic results and patient satisfaction.
• It provides a valuable, less invasive option for patients seeking facial rejuvenation without traditional surgical facelifts.
