Background: Hyaluronic acid–based dermal fillers are the most applied medical devices for midface augmentation.

Objectives: This postmarket investigation evaluated the long-term performance and safety of and patient satisfaction with Princess VOLUME PLUS Lidocaine (PVPL; now Saypha VOLUME PLUS Lidocaine) for the correction of midface volume deficit (MVD).

Methods: This was an open-label, prospective, interventional, multicenter, noncomparative, postapproval study of 91 patients with moderate or severe MVD (grade 2 or 3 on the 5-point Midface Volume Deficit Severity Scale, or MVDSS). At Day 0 (Visit 1), patients were treated with PVPL; they returned for follow-up assessments at weeks 2, 4, 12, 24, 36, and 52 and had long-term follow-up until 36 months. A touch-up treatment could be done at week 2. The performance was assessed with the MVDSS, Global Aesthetic Improvement Scale (GAIS), and a subject satisfaction scale. Adverse events were collected to assess safety throughout the study.

Results: Four weeks after treatment, 100% of injected patients improved by ≥1 grade on the MVDSS compared to baseline, with improvements still visible in 77% of patients 52 weeks after treatment. Based on the GAIS and post hoc survival analysis, the treatment effect was maintained for a median of 386 days, and in severe cases the effect lasted longer, which seemed to be independent of the volume injected at baseline. No serious side effects were reported. Results were substantiated by high patient satisfaction.

Conclusions: Princess VOLUME PLUS Lidocaine was perceived as safe and effective by patients and investigators, with long-term aesthetic improvement in moderate and severe cases.
