[Management of complications after aesthetic hyaluronic acid injections].

The use of hyaluronic acid fillers for treatment of rhytides (wrinkles) is widespread in aesthetic dermatology and is considered a safe procedure; however, complications can occur especially if the injections are carried out by an inexperienced person and/or with a lack of anatomical knowledge. The two cases presented here exemplify this problem. In conclusion, both cases demonstrate complications after uncritical injection of hyaluronic acid fillers into "risk" or "expert" regions. While the patients in these two cases recovered completely, the injection of filler substances can also lead to the risk of potentially permanent side effects, such as granuloma, necrosis with scar tissue formation and even blindness. The frequency and severity of complications often show a direct correlation with the qualification or expertise of the person treating and hence injection treatments should be performed solely by physicians.
