Efficacy and tolerability of admixing 0.3% lidocaine with Dermicol-P35 27G for the treatment of nasolabial folds.

Abstract

BACKGROUND:

Dermicol-P35 27G, an advanced collagen dermal filler, is effective for nasolabial fold (NLF) correction.

OBJECTIVES:

To compare the efficacy and tolerance of Dermicol-P35 27G premixed with lidocaine with that of Dermicol-P35 27G injected after topical anesthesia for NLF correction.

MATERIALS AND METHODS:

In a split-face protocol, 10 patients were injected with Dermicol-P35 27G/topical anest:esia or Dermicol-P35 27G/0.3% lidocaine. Patients were monitored for adverse events and for pain using the Thermometer Pain Scale (TPS) and a visual analog scale (VAS). Efficacy was measured using the Modified Fitzpatrick Wrinkle Scale and the Global Aesthetic Improvement Scale.

RESULTS:

Patients experienced significantly less pain with Dermicol-P35 27G/0.3% lidocaine than with Dermicol-P35 27G/topical anesthesia (mean clinician-assessed TPS scores +/- standard deviation: 2.0 +/- 0.8 and 5.2 +/- 2.1, respectively, p<.001). Patients reported less discomfort with Dermicol-P35 27G/0.3% lidocaine than with Dermicol-P35 27G/topical anesthesia (mean VAS scores: 2.0 +/- 1.0 and 6.3 +/- 2.0, respectively, p<.001; TPS scores: 2.3 +/- 0.6 and 5.4 +/- 1.2, respectively, p<.001). Both treatments yielded similar efficacy scores and were well tolerated. Adverse events were mild.

CONCLUSION:

Dermicol-P35 27G/0.3% lidocaine resulted in less pain than Dermicol-P35 27G/topical anesthesia, with no observed reduction in efficacy.
