title: Reconstruction of the breast using polyurethane-coated prostheses.
abstract: We have inserted 302 Natural-Y polyurethane-coated implants in 92 patients. Follow-up time for the cases studied ranges from 6 months to 41/2 years after reconstruction. None of our patients was observed to develop capsular contracture, and the foreign-body reaction to the polyurethane was of no clinical significance when the implants were placed in a total muscle pocket. Four cases of ruptured prostheses were observed. Overall, the excellent aesthetic results of the polyurethane-coated prostheses were encouraging, resulting in soft, natural-feeling, and aesthetically pleasing breasts.
