Bridging the Gap Rather Than Filling the Entire Valley-Anatomic Insights When Treating the Medial Infraorbital Region.

The results of this retrospectively investigated case series revealed that the conducted injection technique for treating the tear trough for medial infraorbital hollowing with a cannula provided statistically significant clinical improvement with a limited adverse events profile. The technique utilized an injection approach which was perpendicularly oriented to the longitudinal axis of the tear trough thereby "bridging the gap instead of filling the entire valley."
