The premaxillary space: a location for filler injection?
BACKGROUND
A four-layer fat structure is found in the anterior cheek region. The deepest of these fat layers is the premaxillary fat.


OBJECTIVE
To determine whether the premaxillary fat is located in a closed compartment and whether injection of substances affects the appearance of the face.


METHODS
Filler or arterial mass (0.5-0.8 mL) after Thiel were injected, and gross dissections, horizontal and sagittal sections, and three-dimensional reconstructions with computed tomography were performed.


RESULTS
The premaxillary fat is located in a semiopen space, the premaxillary space, with mainly bony and muscular borders. The injected substances spread in lateral and superficial located tissues.


CONCLUSIONS
Injection of substances into this space leads to discrete improvements in the appearance of the nasolabial groove.
