Randomized Controlled Trial
Controlled, randomized study of pain levels in subjects treated with calcium hydroxylapatite premixed with lidocaine for correction of nasolabial folds.
Calcium hydroxylapatite (CaHA) has been administered after nerve block injection of anesthetic agents. ⋯ Investigators concluded that CaHA premixed with lidocaine results in significant pain reduction during dermal filler injection while maintaining the aesthetic improvement of CaHA without lidocaine and demonstrating comparable local transient adverse events for treatment and control. BioForm Medical (San Mateo, CA) provided the soft tissue filler, lidocaine, and other necessary supplies used in this study. All authors are members of the Bioform Medical Education Faculty.
