Differentiating Nonpermanent Injectable Fillers: Prevention and Treatment of Filler Complications

Abstract

Though the incidence of complications and adverse events with dermatological fillers is inherently low, practitioners should be well versed in both prevention of filler complications and the treatment algorithms for addressing "granulomas," nodules, infection, and vascular compromise. Appropriate preventative measures, coupled with timely and effective treatment, are critically important for patient safety and satisfaction. In addition to the preventive measures and treatment algorithms outlined here, the authors emphasize that the broad classification and treatment of nodules as "granulomas" is likely to lead to ineffective treatment, or worse, unnecessary exposure to incorrect treatment. In practice, nodules are classified and treated based on clinical manifestation (eg, late vs early or noninflammatory vs inflammatory) rather than on histology. Indeed, classification of a nodule as a granuloma requires a histological examination, rarely available (or necessary) in clinical practice to guide treatment. Thus, the apparent inflammatory nature of the nodule and the time of onset should drive treatment approach. The treatment algorithms presented here are based on these clinically meaningful parameters.
