title: Weight Measurement and Volumetric Displacement of Breast Implants and Tissue Expanders: Why Port and Shell Volumes Matter in Breast Reconstruction, Augmentation, and Revision.
abstract: There are significant differences in weight and volumetric characteristics between silicone and saline breast implants of which most plastic surgeons are unaware. Phase I of this study was a weight measurement focused on recording differences in the weight of saline volumes instilled versus recorded weights of saline implants and expanders. Phase II compared displaced volume differences of tissue expanders with instilled volumes. As a result of this study, surgeons should now be able to precisely calculate the volume created for breast pocket development, allowing for accurate matching of expander and final breast implant.
