Abstract Buttock augmentation is a commonly performed aesthetic surgery. Several methods have been described, but only the use of implants or autologous fat is consensually deemed safe and effective. Synthetic fillers in gluteal augmentation have been described despite potential severe long-term complications, both medical and aesthetic. The aim of this study is to report a series of 2 consecutive cases who underwent buttock and hip augmentation with large volumes of permanent copolyamide filler requiring surgical removal due to significant complications. Based on these cases and a review of recent literature, a management algorithm is proposed. The authors conducted a retrospective chart review of 2 consecutive cases of failed copolyamide filler augmentations in the gluteal and inguinal regions. The authors conducted a literature overview using PubMed (National Institutes of Health, Bethesda, MD) and Google Scholar (Google, Mountain View, CA) to include all articles concerning the removal of large quantities of permanent copolyamide fillers. Based on the physical properties of copolyamide, resection of the filler was performed by percutaneous aspiration with liposuction cannulas, with varying infiltration protocols. Both cases showed successful removal of major parts of the filler; however, residual material tended toward migration, requiring a secondary intervention. Hydrated low-pressure aspiration can manage nonintegrated gluteal copolyamide filler but will achieve only partial resection. Literature shows that radical excision is possible, however, with major drawbacks in function and aesthetics. Moreover, in acute inflammation and infection, an open approach should be preferred.
