Coiled Polydioxanone Threads (JAMBER) for Nasal Augmentation: Efficacy, Longevity, and Safety

Area of Science:

• Aesthetic Medicine
• Plastic Surgery
• Regenerative Medicine

Background:

• Polydioxanone threads, specifically JAMBER (JB) threads, are explored as a safe alternative for facial volume augmentation.
• This study focuses on evaluating JB threads for nasal augmentation, assessing efficacy, safety, and longevity over 12 months.

Purpose of the Study:

• To evaluate the efficacy, safety, and longevity of JAMBER (JB) threads for nasal augmentation.
• To track changes in nasal height and volume following JB thread insertion over a 12-month period.

Main Methods:

• Retrospective analysis of 23 patients undergoing nasal augmentation with JB threads.
• Utilized ultrasound and 3D scanner imaging at multiple intervals (1-12 months) to assess changes.
• Average of 2.85 JB threads in the nasal dorsum and 1.75 in the columella were used.

Main Results:

• JB thread diameter decreased from 1.113 mm to 0.857 mm, indicating gradual absorption.
• Soft-tissue thickness increased (1.213 mm to 1.403 mm), suggesting collagenesis.
• Nasal volume and height showed significant increases, stabilizing by 12 months (volume: 0.552 mL, height: 1.005 mm).
• No complications like infection or extrusion were reported.

Conclusions:

• JAMBER (JB) threads are effective for long-lasting nasal augmentation.
• They present a safer, minimally invasive alternative to fillers and implants, avoiding vascular risks.
• Precise technique and patient selection are crucial for optimal outcomes.
