Volumizing Thread (Sihler Volume Thread) Technique for Infraorbital Hollowness and Midcheek Groove

Infraorbital hollowness significantly impacts facial aesthetics, contributing to a tired and aged appearance. Traditional treatments, such as fillers and botulinum toxin, can lead to unnatural results. Volumizing threads offer a minimally invasive alternative for enhancing infraorbital and midcheek areas.

This study aims to evaluate the efficacy and safety of using absorbable polydioxanone (PDO) volumizing threads in treating infraorbital hollowness and midcheek grooves.

Three patients with infraorbital hollowness underwent treatment with PDO threads (Volume Thread, Sihler Inc., Seoul, Korea). Threads were inserted using a cross-technique under the orbicularis oculi muscle to enhance volume and firmness. Outcomes were assessed based on patient satisfaction, clinical improvement, and adverse effects over a 6-month follow-up period.

All patients showed significant improvement in infraorbital volume and skin firmness, with a natural appearance maintained. Minor adverse effects, such as bruising, resolved within a week. No major complications were reported.

PDO volumizing threads are a safe and effective option for infraorbital hollowness and midcheek groove correction, providing natural results with minimal complications.
