Objective To analyze the causes and explore suitable treatments for the complica-tions induced by polyacrylamide hydrogel (PAHG) injection for augmentation rhinoplasty. Methods The causes of the complications of 52 cases who accepted PAHG injection for augmentation rhinoplas-ty were analyzed and summarized. All the patients were treated by surgical operations to remove the injected PAHG. Results The complications included infection, granuloma, skin ulceration, bad shape, pain and serious psychological stress. Each case had 1 to 4 complications. Satisfactory results were obtained after suitable treatments. Some cases had silicone or expanded polytetrafluoroethylene implant augmentation rhinoplasty at the same time or secondary to the PAHG removal. A few cases had sequelae and long time psychological stress or tend pain of nose. Conclusions The complications induced by PAHG injection for augmentation rhinoplasty are various, and may relate to the inherent character of PAHG and the anatomic features of the nasal soft tissue. Surgery can remove the PAHG as completely as possible, which is a better method to treat the complications of PAHG injection for augmentation rhinoplasty.
