Augmentation mammaplasty--a further review of 20 years using the polyurethane-covered prosthesis.

Augmentation mammaplasty continues to attract much attention. So far, it seems to be an operation with an indefinite endpoint regarding the longevity of results. It is also a procedure that has wide monetary implications and would often seem to be inappropriately used. With the advent of the latest polyurethane-covered prostheses, marketed under various trade names such as Meme, Replicon, and Optimam, a more predictable result can be obtained, at least for the first 6 years. Much controversy still exists, and in view of this, the authors have revised their long-term results and comments on important current aspects.
