Abstract

Background: Hyaluronic acid (HA) fillers are FDA approved for improving the appearance of the nasolabial folds. Previous reports on the use of HA for this treatment have focused on injections directly into the location of the desired correction. To our knowledge, a study has not been done evaluating the efficacy of injecting a low volume of HA into the adjacent area of volume loss to correct both volume loss and adjacent lines. Objective: The objective of this study was to compare the effectiveness and safety of three HA injection protocols including deep dermal cheek injection, mid- to deep dermal local nasolabial fold injection, and both injections for the correction of nasolabial folds. Methods: This was a split-face, randomized study evaluating the use of three injection techniques - (i) deep bolus injection into the mid- to lateral cheek, (ii) local mid- to deep dermal injection into the nasolabial fold, and (iii) both deep injection into the mid- to lateral cheek and local mid- to deep dermal injection into the nasolabial fold - for the treatment of moderate to severe nasolabial folds. Wrinkle severity and Global Aesthetic Improvement Scales were measured before and 4-6 weeks after treatment as assessed by a blinded investigator. Results: Patient and physician observations showed improvement both globally and in wrinkle severity score with each technique used with no statistical difference between techniques. Patients showed a slight preference for injection to both the mid- to lateral cheek and nasolabial fold, which was associated with the greatest amount of filler product administered. No serious adverse events were reported. Conclusion: Injection of a dermal filler, at low volumes, into either the nasolabial fold or mid- to lateral cheek results in similar improvement to the correction of the nasolabial folds.
