Abstract

Abstract : Background: Deepening of the nasolabial fold with reduced malar highlight caused by sagging of the midface is one of the most important characteristics of facial aging. This report describes the use of 18-G polydioxanone (PDO) cog threads to improve midface soft tissue sagging and achieve satisfactory results through a minimally invasive procedure. Methods: In total, 64 patients (all women; age, 33–60 years) underwent a midface thread lift from January 2017 to January 2018. After a stab incision was made through an 18-G needle over the lateral orbital rim, three 18-G precannulated PDO cog threads were inserted, targeting the deep medial fat pad and inner layer of the superficial muscular aponeurotic system. The threads were anchored to the periosteum of the lateral orbit, suspending the soft tissue to a more superior direction. Surgical results were evaluated subjectively (patient satisfaction ratings) and objectively (blinded physician ratings based on changes in the vertical position of the malar highlight). Results: No major complications (postoperative hematoma, infection, or temporary sensory/motor decreases) were observed. The mean procedural time was 15 minutes, and all patients underwent local anesthesia. Patient satisfaction was the highest at 1 month postoperatively (mean, 4.7/5.0), decreasing at 1 year postoperatively (2.8/5.0). The scores on the objective assessment followed the same trend (4.5/5.0 at 1 month; 3.1/5.0 at 1 year). Conclusion: Using PDO cog threads for midface lifting is simpler, quicker, and less invasive than using conventional surgical methods, and this method simultaneously achieves satisfactory results for at least 6 months.
