Retrospective real-world study of Definisse threads for jaw line reshaping in Indian patients (REDEFINE JAW study)

Background

Thread lifting is a minimally invasive aesthetic procedure that lifts and realigns sagging tissue. Definisse double-needle threads are the latest fourth generation absorbable, monofilament, suspension barbed threads of synthetic origin with convergent bidirectional barbs. Definisse thread produces dual action; mechanical action gives a lifting effect and over a period, it promotes histological revitalizing action.

Objectives

To evaluate the real-world efficacy and safety of Definisse double-needle threads for lower facial lifting for jaw line reshaping in Indian patients.

Methods

This is an observational, retrospective study involving patients who underwent treatment for lower-face reshaping using Definisse double-needle 12 cm threads.

Results

Fifty patients with a mean age of 47.44 years were included in the study with an average follow-up of 5.14 months. All the patients have undergone Jawline Reshaping (JR) procedure, while 70% of patients also underwent Malar Reshaping (MR) technique simultaneously. Mean of Physician and Subject Global Aesthetic Improvement Scale (PGAIS and SGAIS) showed improvement immediately after the procedure (mean scores 2.82 and 2.7, respectively) and showed further improvement at the follow-up (3.72 and 3.58, respectively). Moreover, most of the patients immediately after the procedure rated the improvement in PGAIS and SGAIS as “much improved” compared to pre-procedure appearance (78% and 66%, respectively), while, at follow-up, 76% and 66% of the patients, respectively, rated “improved very much” compared to pre-procedure appearance.

Conclusion

Current study has demonstrated the effectiveness of the latest Definisse threads in Indian patients in performing tissue repositioning to provide a noticeable lifting effect. Procedure was also well tolerated and none of the patients developed serious complications.
