Navigating the Labial Artery: A Safer Approach to Submucosal Lip Filler Techniques

Area of Science:

• Aesthetic Medicine
• Dermatology
• Plastic Surgery

Background:

• Hyaluronic acid (HA) fillers are popular for lip augmentation.
• Vascular complications remain a significant risk in lip augmentation procedures.
• Existing techniques may pose risks due to proximity to labial arteries.

Purpose of the Study:

• To evaluate a novel vertical injection technique for submucosal HA filler placement in lip augmentation.
• To enhance safety and achieve natural-looking aesthetic outcomes.
• To minimize the risk of vascular complications, specifically labial artery injury.

Main Methods:

• Ultrasound-guided vertical injections of HA fillers into submucosal intralabial compartments.
• Predefined entry points were utilized to target specific anatomical areas.
• Ten patients underwent lip augmentation using the novel technique.

Main Results:

• High patient satisfaction reported with significant improvements in lip volume and contour.
• Submucosal placement resulted in subtle, natural outcomes with reduced irregularities.
• No major vascular complications observed; minor side effects like swelling and redness resolved within 48 hours.

Conclusions:

• The novel vertical injection technique offers a potentially safer and effective method for lip augmentation with HA fillers.
• Ultrasound guidance is crucial for precise filler placement and risk mitigation.
• Further research with larger sample sizes and longer follow-up periods is warranted.
