Abstract

Background: Small-particle calcium hydroxylapatite (Radiesse, Merz, Frankfurt, Germany) is safe and effective for facial wrinkle reduction, and has medium-term persistence for this indication. There is patient demand for similar fillers that may be longer lasting. Objective: We sought to assess the safety and persistence of effect in vivo associated with use of large-particle calcium hydroxylapatite (Coaptite, Merz) for facial augmentation and wrinkle reduction. Methods: This was a case series of 3 patients injected with large-particle calcium hydroxylapatite. Results: Large-particle calcium hydroxylapatite appears to be effective and well tolerated for correction of facial depressions, including upper mid-cheek atrophy, nasolabial creases, and HIV-associated lipoatrophy. Adverse events included erythema and edema, and transient visibility of the injection sites. Treated patients, all of whom had received small-particle calcium hydroxylapatite correction before, noted improved persistence at 6 and 15 months with the large-particle injections as compared with prior small-particle injections. Limitations: This is a small case series, and there was no direct control to compare the persistence of small-particle versus large-particle correction. Conclusions: For facial wrinkle correction, large-particle calcium hydroxylapatite has a safety profile comparable with that of small-particle calcium hydroxylapatite. The large-particle variant may have longer persistence that may be useful in selected clinical circumstances.
