Long-term follow-up of a sponge breast implant and review of the literature.

Abstract

A case of a woman who underwent removal of a breast implant consistent with a polyvinyl sponge contained within a polyethylene bag is described. The use of the polyvinyl alcohol sponge as a breast implant virtually ceased in the mid 1960s with the introduction of silicone gel breast prostheses. However, it is still possible that the plastic surgeon may encounter a patient with one of these sponge implants in place. Thus, it is important for the plastic surgeon to be aware of their existence, natural history, and potential late complications. In addition, since the removal of silicone from general use for augmentation mammaplasty, there have been intense efforts to identify new filler materials for use in breast implants. Polyvinyl alcohol has been considered a possible material. There is a paucity of information in the recent literature pertaining to the characteristics and use of polyvinyl alcohol sponge implants. Therefore, this report describes a patient treated 38 years following placement of this type of implant and reviews the literature.
