OBJECTIVETo analysis various complications of 30 patients of breast augmentation by injected polyacrylamide hydrogel and discuss the treatment through periareolar incision.

METHODSAll patients were classified according to the different complications. Open suction technique and partial mastectomies via periareolar incisions were performed in all patients, Only one patient had immediately breast reconstruction with prosthesis, five patients received secondarily breast prostheses implantation via a axillary incision.

RESULTAll the symptoms were relieved after remove of polyacrylamide hydrogel.

CONCLUSIONSPolyacrylamide hydrogel should be prohibited for injected breast augmentation at present. A double-blinded randomized clinical study, controlled animal experiments and a large sample questionnaire survey for complications are necessary. The periareolar approach is valuable technique and can remove polyacrylamide hydrogel as completely as possible.
