Objectives: Injectable fillers are usually considered to be used to fill wrinkles, folds or localize areas of volume loss. However, we can achieve lifting effects while using the in lateral aspects of the line of ligaments.
For this reason, we wonder if using filler injections in lateral area we can reposition facial structures with minimal quantity of filler. We want generate a new protocol based on the line of ligaments to improved results to minimized volumizing treatment.
Introduction: Age-related changes are observed in all tissues. Rejuvenate procedures should aim patient´s safety, deeply understanding of anatomic layers, and obtain long lasting results.
The imaginary vertical line that connects 4 major facial ligaments: temporal ligament of adhesion, lateral orbital thickening, zygomatic cutaneous ligament, and mandibular ligament. This line separates the face into a medial and lateral side.
We propose to infiltrate fillers into the lateral part for lifting effects, and into the medial part for volumizing effects.
Materials / method: We treated 8 patients. The aim was to treat laxity and sagginess in the lateral part and volume loss in medial midface. We infiltrated a high cohesive hyaluronic acid into subcutaneous and supraperiosteum level. The product was placed in 0.1-0.5ml boluses or 0.5ml fan technique.
We lift these major 4 ligaments with injections in these points:
- Temporal cavity: we injected in supraperiosteum with gunshot technique, 0.5 ml
- Zygomatic arch: we injected 3 boluses in supraperiosteum
- Pre-parotid area: we injected 0.5 ml
- Mandibular angle: we injected 0.3-0.5ml in supraperiosteum
Results: Four patients were injected following our ligament line model. In these patients, we can observe improvement in nasolabial and nasogenian folds, relocation of jowls and cheek projection. As we can show in images, the injection of hyaluronic acid in medial part to volumize were not necessary.
On the other hand, four patients were treated in lateral and medial areas. We can observe that when we firstly injected in lateral areas, we need less hyaluronic acid to volumize in medial areas. Only, it was necessary inject 0.3-0.5 ml of product in medial areas, minimizing “puffy” faces outcomes.
Conclusion: Our ligament line proposed model is based in anatomic points. This model shows that lateral injections result in the stretching and flattening effect of the midface soft tissues and fat compartments get smoothed by the applying stretch on the facial layers.
The main result of this study is to make real emphasize in the importance of facial anatomic boundaries, where soft tissue fillers can be placed not only safely without distorting anatomy or creating puffy faces, but also using less amounts of filler when the first target are lateral injection points.
