Customized silicone implants of the breast and chest.

Custom-fabricated silicone implants were used in 17 patients to reconstruct thoracic deformities associated with pectus excavatum, hypoplasia of the thorax, and radical mastectomy. The implants have been in place an average of 2 1/2 years. Custom implants have been permanently removed in only two of these patients. These implants can provide accurate, complex contour restoration without creating donor defects. However, problems of extrusion, capsule formation, slippage, and infection requiring implant removal are characteristic of nonautogenous materials. Because these are foreign bodies, well-vascularized soft-tissue coverage is especially essential to retain these implants.
