Objective To explore the indication of implant prosthesis immediately after removing polyacrylamide hydrogel for augmentation mammaplasty. Methods MRI and pathologic examinations were made in 226 patients with the postoperative complications of augmentation mammaplasty by injecting polyacrylamide hydrogel and with the specific conditions in operation to analyze the possibility of implant prosthesis while removing polyacrylamide hydrogel. Based on MRI examination, physical examination and specific conditions in operation, we chosen 61 cases who requested for implant prosthesis while removing polyacrylamide hydrogel. Results The patients who did the operation for simply removing polyacrylamide hydrogel recovered well and symptoms such as pain, sclerosis, mass and others disappeared almostly; the patients who did implanting at the same time were satisfied with the breast shape and had no side-effect occured. Conclusion With MRI examination, physical examination and specific conditions in operation, it can achive good effects to do implanting immediately after removing polyacrylamide hydrogel for those suitable and willing to implant prosthesis.
