title: "Walk the Rim, Feel the Bone" Technique in Superior Sulcus Filling.
abstract: Superior sulcus filler injection is a nonsurgical method to rejuvenate the upper face. Blindness and stroke are devastating complications of facial filler injection. This study describes an injection technique that minimizes the risk of blindness and includes a case study demonstrating the cosmetic benefits of this procedure. To avoid retrograde injection of filler embolus into the ophthalmic artery, we advocate a "'walk the rim, feel the bone" approach. Small boluses of hyaluronic acid filler are given in preperiosteal plane, avoiding the superior orbital foramen.
