Quantitative evaluation of volume augmentation in the tear trough with a hyaluronic Acid-based filler: a three-dimensional analysis

Plast Reconstr Surg. 2010 May;125(5):1515-1522. doi: 10.1097/PRS.0b013e3181d70317.

Abstract

Background: Despite the prevalent use of hyaluronic acid-based filling materials for facial soft-tissue augmentation and favorable reports of durability in the infraorbital region, no quantitative data exist on the long-term durability of these products following injection. This study represents the first attempt to use three-dimensional imaging to quantify augmentation achieved and duration of effect with one hyaluronic acid product in the tear trough.

Methods: The authors conducted a prospective, blinded case series in a clinical setting. One non-animal stabilized hyaluronic acid material was used to augment 20 tear troughs to address cosmetic deficiency in this region. Patients were followed long term with three-dimensional imaging. Posttreatment and pretreatment images were compared, volume change was calculated at each time point, and percentage change between immediate and long-term posttreatment was evaluated. All measurements and calculations were performed independent of the injector.

Results: Residual effect from the hyaluronic acid product was demonstrable on three-dimensional imaging in 100 percent of tear troughs augmented in this study at the final follow-up visit. Average follow-up was 14.4 months (range, 8.5 to 22.75 months). Average initial augmentation measured by three-dimensional imaging was 0.21 cc per site. Average maintenance of effect for patients at the final follow-up visit was 85 percent.

Conclusions: The long-term durability of a small gel particle-based hyaluronic acid in the tear trough is substantiated for the first time in an objective, quantitative fashion using three-dimensional imaging for evaluation of volumetric facial rejuvenation. Three-dimensional photographic imaging offers clinicians a precise and expeditious method for quantitatively evaluating volumetric changes in the face, and represents a significant advance in technology for studying the effects of facial aging.
