Synovial metaplasia was seen in the capsular tissue from both types of implant, but more so from capsules surrounding polyurethane implants more than 5 years old. The density and orientation of the collagen fibers and the foreign body reaction were very similar for the two types of implant.
This article reports the experience acquired through the use of ultrasonography applied to the study of the mammary gland affected by augmentation or reduction mammaplasty. Thirty-eight patients who had undergone either augmentation or reduction mammaplasty were submitted to ultrasonographic examination. Such a technique, besides being easy to perform, noninvasive, specific, and well accepted by the patients, showed to be remarkably interesting. It offered a wide display of the mammary parenchyma, showing its possible alterations, and supplying useful information on any possible postoperative implant ruptures, cicatricial reactions, seromas, and any other possible alterations that occurred.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
