Summary
A novel 9-point injection technique (9-PIT) safely enhances lips with hyaluronic acid (HA) filler, achieving aesthetically pleasing results and lip corner elevation without adverse events.
Area of Science:
- Aesthetic medicine
- Dermatology
- Plastic surgery
Background:
- Lip enhancement with fillers is increasingly popular.
- Need for safe injection techniques to avoid complications like arterial injury.
Purpose of the Study:
- Establish a safe injection technique for aesthetically pleasing lips.
- Achieve lip corner elevation using filler.
Main Methods:
- Sonography identified labial arteries.
- A 9-point injection technique (9-PIT) was developed.
- Hyaluronic acid filler administered to 50 patients, monitored for 3 months.
Main Results:
- Vascular pathways elucidated; no adverse events reported.
- Lip corners lifted by 1.02 mm, angle decreased 8.80%.
- Upper lip S-shape enhanced, length increased 6.5%.
Conclusions:
- 9-PIT provides safe and consistent lip volumization and corner elevation.
- Hyaluronic acid filler effectively achieved lip corner lift.
- Technique elucidates vascular anatomy for safer injections.
