Treatment of tear trough deformity with hyaluronic acid gel filler

Abstract

Volume loss and muscular hyperactivity are two major components of the aging process that contribute to the formation of the folds and wrinkles. Tear trough deformity is one of the most difficult depressions to correct surgically. Since January 2007, 150 patients have had their tears troughs treated with hyaluronic acid gel filler. Restylane® was used to treat all patients and it was injected in the preperiosteal tissues just inferior to the orbital rim. The mean volume per side needed to achieve correction was on the right side 0.63 ml (SD ∈= ∈0.37) and on the left side 0.6 ml (SD ∈= ∈0.3). Most common complications were some degree of bruising, erythema, local swelling, and pain at injection site. The effect of treatment has been lasting up to 18 months. All patients are very satisfied with their results.
