A protocol for facial volume restoration with poly-L-lactic acid

Area of Science:

• Biomaterials science
• Dermatology
• Plastic surgery

Background:

• Poly-L-lactic acid (PLLA) is an injectable biodegradable synthetic polymer for subcutaneous volume restoration.
• Its mechanism involves a foreign body tissue response, promoting fibroblast production and neocollagenesis.
• Despite widespread use, there's limited published guidance on PLLA injection techniques.

Purpose of the Study:

• To present a detailed protocol for the correct injection technique of PLLA.
• To address the scarcity of information regarding PLLA administration.
• To guide practitioners in achieving successful volumetric correction and minimizing unintended outcomes.

Main Methods:

• A protocol for PLLA injection into the submalar and buccal regions is described.
• The technique focuses on appropriate placement for effective volume restoration.
• Emphasis is placed on critical aspects of injection to prevent adverse effects.

Main Results:

• The presented protocol facilitates successful PLLA administration.
• Correct technique is crucial for achieving desired volumetric correction.
• Proper PLLA placement minimizes the risk of long-lasting, unintended aesthetic results.

Conclusions:

• Mastering PLLA injection technique is essential for practitioners.
• This protocol provides a reliable method for submalar and buccal volume restoration.
• Adherence to proper technique ensures patient safety and optimal aesthetic outcomes with PLLA.
