Improving mandibular contour: A pilot study for indication of PPLA traction thread use.

Area of Science:

• Aesthetic Medicine
• Dermatology
• Plastic Surgery

Background:

• Increasing demand for non-surgical mandibular contouring.
• Limited research on poly-L-Lactic acid (PLLA) traction threads for this application.
• Exploration of novel thread-based rejuvenation techniques.

Purpose of the Study:

• To evaluate the efficacy of PLLA traction threads in enhancing mandibular contour.
• To identify patient characteristics influencing treatment outcomes and longevity.
• To document procedural complications and patient satisfaction.

Main Methods:

• Prospective study involving 20 female patients with varying skin laxity.
• Bilateral application of PLLA traction threads in a single session.
• Statistical analysis (Fisher's t-test) to correlate factors with result longevity.

Main Results:

• Treatment longevity is associated with younger age, absence of severe skin laxity, and aesthetic satisfaction.
• Common side effects include temporary edema, swelling, and contour irregularities (80%).
• Paresthesia occurred in 10% of patients, resolving within 2-4 weeks.

Conclusions:

• PLLA traction threads are effective for selected patients with mild-to-moderate jawline and neck laxity.
• Ideal candidates are under 51 years old, demonstrating good aesthetic outcomes.
• Further research is warranted to validate these findings.
