(a) What is PDO? PDO suture lift also known as (polypropylenesuture) is an absorbable serrated thread manufactured by Johnson & Johnson. It takes about 4-6 months to absorb. The serrations on its surface are in a 360° rotating wrap design. Its material is the same as PDS suture. the introduction of PDO suture provides the possibility of buried facial lift. (2) Why is PDO a milestone in the field of facial rejuvenation? Lifting and anti-aging is the eternal theme. The original serrated wire lift is made of silicone rubber or polyester fiber which is not absorbable. Patients were concerned about the potential for foreign bodies to remain in the face. The subfacial lift with toxic toxins has a jaw tightening and lifting effect, which is slightly more effective. And facial wrinkle removal cannot be widely promoted due to the large trauma. (C) The principle of PDO face lift? The upward lifting effect can be achieved after the chamfered teeth on the PDO serrated suture are implanted in the subcutaneous SMAS fascia layer. Through the fixation of the upper end, nasolabial fold lifting, marionette lifting, apple muscle lifting, upper lid and eyebrow lifting, frontal temporal lifting, etc. can be realized. Its lifting effect is far greater than that of Botox and hyaluronic acid to achieve minimally invasive age reversal. (D) Is PDO lift safe? PDO lift is very safe, from the material point of view, it can be absorbed by its own body, no hidden danger of foreign body existence, from the surgical technique, patients only need a few pinhole-sized incisions, you can bury the sutures and lift, no hidden danger of facial scarring. The only possibility of intraoperative PDO threads pulling the facial nerve and causing temporary facial nerve injury symptoms, which can generally be fully recovered within 24 hours. (E) What is the effect of PDO lifting? PDO lift is suitable for men or women over 40 years old, and its lifting effect is sure. The surgeon will design the position and direction of the buried wires according to the patient’s facial sagging area and degree. The maintenance effect is about 1.5 to 3 years. In case of re-sagging, the procedure can still be repeated several times.
