BACKGROUND: Polyacrylamide hydrogel (PAHG) is widely used in biomedical research and industry and has been used as a soft tissue filler in some countries for more than a decade. OBJECTIVE: The author evaluated the results of malar area augmentation with PAHG. METHODS: Results from 1306 patients who were treated with PAHG for soft tissue augmentation of the malar area from 2000 to 2006 were retrospectively assessed. Follow-up ranged from 3 months to 6 years. RESULTS: Patients were initially satisfied in 95% of cases (1241 patients). In 5% of cases (65 patients), patients were not satisfied with the result because the injected volume was insufficient. Adverse events occurred in 8.4% of cases (111 patients) with lumps, gel displacement, and pain being the most frequent complications. CONCLUSIONS: In our experience, PAHG has proven to be a safe material for achieving facial soft tissue augmentation with minimal side effects. A follow-up study is necessary to evaluate longer-term results and possible side effects of augmentation with PAHG.
