Over the past 5 years the use of polyurethane-covered prostheses in aesthetic and reconstructive breast surgery has increased dramatically as plastic surgeons have become aware of at least three distinct advantages: (1) low incidence of capsular contracture, which occurs with their primary (2) provision of a predictably successful method of treatment of capsular contracture resulting from the use of smooth-surface silicone implants9-13; position^.^.^^ Although the incidence of major complications occurring with the use of polyurethane-covered prostheses is low, surgeons using them must be aware of certain variations of diagnosis and treatment. Other than rash and surface wrinkling, the complications that occur with polyurethane-covered implants are similar to those seen with standard silicone prostheses. However, there are some unique complication features that require experience to recognize and treat appropriately. The following complications are discussed: (1) infection, (2) rash, (3) recurrent capsular contracture, (4) hematoma, (5) seroma, (6) implant malposition, (7) implant rupture, (8) implant wrinkling, and (9) palpation of implant edge.
INFECTIONThe perception held by some surgeons that the rate of infection is greater with the use of polyurethane-covered implants than with the smooth-surface variety is unfounded. Brand14 has confirmed this fact in an animal model, and clinical reports of infection rates with smooth-surface and polyurethanecovered implants in both aesthetic and reconstructive breast surgery fail to show an increased risk with the polyurethane-covered implant.3-7~9.10~15-19 However, when infection does occur following the placement of a polyureDownloaded by: National University of Singapore.
