Advanced facial rejuvenation: synergistic effects of lower blepharoplasty and ultrasound guided mid-face lift using polydioxanone (PDO) threads
Park, Jun Ho; Jeong, Ji Won; Park, Ji-Ung. (2024) |
To compare the results in patients undergoing lower blepharoplasty combined with a mid-facelift using PDO threads versus those undergoing lower blepharoplasty alone. |
This retrospective study compared the outcomes in patients undergoing lower blepharoplasty combined with mid-facial lifting using PDO threads versus those who underwent lower blepharoplasty alone from March 2019 to December 2022.
Retrospective study. |
The combined procedure demonstrated superior aesthetic outcomes and greater patient satisfaction compared with lower blepharoplasty alone. Improvements were more significant in wrinkle reduction, midface volume, and interzygomatic distance in the combined procedure group. Although the combined procedure had a longer mean operating time, scar assessment scores were similar between the two groups, with no reported complications. |

Experimental investigation of biostimulatory effects after polydioxanone thread insertion in a pig model
Su, Diya; Wang, Shiwei; He, Tong; Wang, Jieqing. (2024) |
To determine collagenation and inflammation changes occurring in adipose tissue over time after different thread type implantation. |
The authors inserted three types of sutures (PDO, PGLA, and nylon) into the subcutaneous fat of 12-month-old Bama miniature pigs. Next, they evaluated collagen production and inflammatory response by hematoxylin and eosin and Masson's trichrome staining 1, 4, 12, 24, and 48 weeks after the procedure.
Observational study. |
PDO suture remained intact for up to 24 weeks with mild inflammation and collagen production. The integrity of the PGLA suture lasted up to 12 weeks and showed a strong inflammatory response. The nylon suture remained intact for 48 weeks, resulting in less inflammation and collagen production. |

Safety and efficacy of restoring facial symmetry using polydioxanone thread face lift technique in patients with facial palsy
Bhatnagar, Anuj; Rai, Roma; Kumar, Sanjay; Mitra, Barnali; Chopra, Ajay; Singh, Gautam Kumar; Mitra, Debdeep; Patil, Chetan; Sandhu, Sunmeet. (2022) |
To test and evaluate the efficacy of restoring facial symmetry using the PDO thread lift technique in patients with facial paralysis. |
Fifty patients with one-sided drooping after facial paralysis underwent treatment with thread lift and botulinum toxin injections to control contralateral hypertrophy and ipsilateral synkinesis. All visits were analyzed using the Facial Scoring System or Sunnybrook Facial Scoring System and serial photographs.
Observational and analytical study. |
After the threading procedure, all 50 patients showed improved facial symmetry. There was a significant improvement in the initial scores compared to those obtained one year later, with a p-value lower than 0.05. |

Experiences of barbed polydioxanone (PDO) cog thread for facial rejuvenation and our technique to prevent thread migration
Unal, Mehmet; Islamoglu, Gizem Kaya; Ürün Unal, Gülbahar; Köylü, Nihal. (2021) |
To evaluate and share the experiences on the efficacy and safety of PDO thread lift for facial rejuvenation and to present a technique to prevent thread migration. |
The study evaluated 38 patients who underwent PDO cog treatment for facial rejuvenation. The authors used a sharp 23 G/90 mm needle to insert a bidirectional barbed PDO thread into the subcutaneous tissue. They evaluated the procedural results using GAIS and patient satisfaction.
Descriptive and analytical study. |
The study included 38 patients with a mean age of 39.6 ± 7.5 years. The GAIS score showed satisfactory outcomes (78.9%, very much improved; 18.4%, much improved; 2.6%, improved). All patients were satisfied with the clinical outcomes of the procedure (76.3%, excellent; 21.0%, very good; 2.6%, good). No patient reported "fair" or "poor" outcomes. |

Facial thread lifting complications in china: analysis and treatment
Li, YL; Li, ZH; Chen, XY; Xing, WS; Hu, JT. (2021) |
To describe the main complications in a group of 190 postoperative facial lifting patients treated after having undergone thread lift in other hospitals. |
From April 2014 to January 2020, the authors treated 190 patients with postoperative facial lifting complications after having undergone thread lift in other hospitals. The sample included 189 females and one male; the patients' ages ranged from 28 to 62 years, with a mean age of 37.4.
Descriptive cross-sectional study. |
The patients treated presented the following complications: skin dimpling (77 cases, 40.5%); contour irregularity (32 cases, 16.8%); visible threads (31 cases, 16.3%); thread extrusion (10 cases, 5.3%); infection (17 cases, 8.9%); swelling (9 cases, 4.7%); incomplete facial paralysis (five cases, 2.6%); hyperpigmentation (four cases, 2.1%); hematoma (four cases, 2.1%); allergy (one case, 0.05%). Follow-up was scheduled for 1 to 24 weeks after treatment. |

Mini-midface lift using polydioxanone cog threads
Myung Y, Jung C. (2020) |
To describe the use of 18-G PDO threads to improve soft tissue laxity of the midface and achieve satisfactory outcomes through a minimally invasive procedure. |
Sixty-four patients (all women, aged 33 to 60 years) underwent a midface thread lift from January 2017 to January 2018. The authors made a penetrating incision using an 18-G needle over the lateral orbital rim to insert three 18-G precannulated PDO threads into the deep medial fat pad and the inner layer of the superficial muscular aponeurotic system. The threads were anchored in the periosteum of the lateral orbit, suspending the soft tissue in a more superior direction. The surgical results assessment was subjective (patient satisfaction ratings) and objective (blinded physician evaluations based on changes in the vertical position of the malar prominence). Descriptive study. |
No major complications (postoperative hematoma, infection, or temporary sensory/motor impairment) were observed. The mean procedure time was 15 minutes, and all patients underwent local anesthesia. Patient satisfaction was highest at 1 month postoperatively (mean, 4.7/5.0), decreasing at 1 year postoperatively (2.8/5.0). Objective assessment scores followed the same trend (4.5/5.0 at 1 month; 3.1/5.0 at 1 year). |

Effectiveness, longevity, and complications of facelift by barbed suture insertion
Bertossi, Dario; Botti, Giovanni; Gualdi, Alessandro; Fundarò, Piero; Nocini, Riccardo; Pirayesh, Ali; van der Lei, Berend. (2019) |
To determine the efficacy, longevity, complications, and postoperative sequelae associated with facial liftings using barbed PDO threads. |
The study retrospectively evaluated 160 consecutive patients who underwent facial liftings with barbed threads. For malar augmentation and correction of nasolabial folds, two or three PDO threads (23 gauge) were inserted per side; for mandibular line treatment, two to four PDO threads (21 gauge) were inserted per side.
Observational study. |
Patients showed improvement in facial tissue ptosis after suture placement and for 1 month postoperatively. This aesthetic result decreased visibly within 6 months and disappeared within 1 year. The overall rate of complications in the immediate postoperative period was 34% (55 of 160 patients). Eighteen patients (11.2%) had superficial displacement of barbed sutures, 15 (9.4%) had transient erythema, 10 (6.2%) had infection, 10 (6.2%) had skin dimpling, and 2 (1.2%) had temporary facial stiffness. |
