Abstract
BACKGROUND: Despite the high demand of filler in the infraorbital area, there remains debate on injection practices, precise anatomical placement, and hyaluronic acid (HA) filler behavior. OBJECTIVES: We aimed to contribute to the clinical and anatomic understanding of infraorbital HA injection through a prospective patient injection study in combination with a cadaveric analysis. METHODS: Patients were injected with Volbella XC (JUVÉDERM, Allergan Aesthetics, an AbbVie Company, Irvine, CA) into the tear trough region by a single experienced aesthetic plastic surgeon. Over a 90-day period, precise undereye volumetric measurements using 3-dimensional photogrammetry (VECTRA-M3, Canfield Scientific, Inc., Fairfield, NJ) and patient-reported outcomes (PROs; FACE-Q) were collected and analyzed relative to 2 pretreatment severity scales. Juvéderm Vycross (Allergan Aesthetics, an AbbVie Company, Irvine, CA) and Restylane NASHA (Galderma, Lausanne, Switzerland) products were injected into the infraorbital and malar region in 6 cephalus specimens and evaluated with regards to the anatomic injection location with and without common clinical physical manipulations. RESULTS: Eleven patients participated with a 100% retention rate. Infraorbital HA volume maintenance was 70% to 81% at 30 days and 50% to 70% at 90 days. Significant improvement was noted in the eyes, overall facial appearance, and cheekbones (P < .05) with FACE-Q outcomes, irrespective of pretreatment severity. In the cadaver examination, we observed differences in the anatomic locations occupied by Juvéderm and Restylane products as well as in behavior after physical manipulation between gel types. CONCLUSIONS: Volbella XC effectively augments undereye volume to diminish infraorbital hollowing as measured over a 90-day period with significantly improved PROs. Enhanced knowledge of the behavior of Volbella XC and other HA fillers in this sensitive anatomic region will lead to improved patient outcomes.
