Gluteal Soft-Tissue Repositioning Using Polydioxane Threads

Abstract

Background: Buttock reshaping has recently gained popularity. Gluteal soft-tissue repositioning can be performed using polydioxane threads, followed by anthropometric measurements.

Objective: To evaluate the effectiveness of polydioxane threads for noninvasive gluteal soft-tissue repositioning.

Materials and methods: From February 2018 to August 2019, 27 women (mean age, 38.9 years; range, 26-65 years) underwent thread lifting. Multiple polydioxane threads (total, 24-30 threads for each buttock side) were used for gluteal soft-tissue repositioning. The treatment outcomes were based on comparisons of the preoperative and postoperative findings.

Results: The mean ratio of the upper and lower vertical proportions of the buttocks changed from 63:37 preoperatively to 55:45 postoperatively. The mean projection angle of the upper portion decreased from 60.1° preoperatively to 54.3° postoperatively. Twenty-four patients (86%) were satisfied with the results up to 8 months postoperatively. One patient developed persistent pain (>1 month), and 4 patients showed skin dimpling, which resolved within 2 weeks after minimal massages. No hematomas, foreign body sensation, or thread protrusions were noted.

Conclusion: Polydioxane threads could be an alternative, minimally invasive tool for buttock lifting. Our novel technique of repositioning the buttock soft tissue improved lifting and augmentation and provided a better buttock shape.
