Abstract
Implants with fillable reservoirs have been developed that are suitable for rhinoplasty, breast reconstruction, ear reconstruction, and replacement, reconstruction or repair of other soft tissues. The implants can be filled with graft material prior to implantation. The implants are preferably made from resorbable polymers, can be tailored to provide different geometries, mechanical properties and resorption rates in order to provide more consistent surgical outcomes. The implants preferably have an interconnected network of unit cells with microporous outer layers and optionally some or all of the unit cells having at least one macropore in their outer layers. The implants can be loaded by injection with microfat, collagen, DCF, cells, bioactive agents, and other augmentation materials, prior to implantation.
