The successful use of silicone breast implants is complicated by their interference with mammography. We have evaluated clinically available implant filling materials and found that a new Bio-Oncotic gel approximates the radiolucency of normal breast tissue. Silicone implants completely obscure areas of the breast in mammography. Recently proposed as a filler material, peanut oil is significantly more radiolucent than normal tissue. Physiologic saline solution compares favorably as a tissue-density-simulating substance. However, saline's lack of lubricating properties results in leakage, making it less than optimal. Bio-Oncotic gel is biologically compatible. We conclude that this gel is the most appropriate filler for breast prostheses. Clinical studies are indicated.
硅胶乳房植入物的成功使用因干扰乳房X光检查而变得复杂。我们评估了临床上可用的植入物填充材料，发现一种新型生物胶体凝胶的射线透过性接近正常乳腺组织。硅胶植入物在乳房X光检查中会完全遮挡乳房区域。最近被提议作为填充材料的花生油，其射线透过性明显高于正常组织。生理盐溶液作为一种组织密度模拟物质表现良好。然而，生理盐水缺乏润滑特性会导致渗漏，使其并非最佳选择。生物胶体凝胶具有生物相容性。我们得出结论，这种凝胶是乳房假体最合适的填充材料。有必要进行临床研究。
