Implantation of three different polymeric composite materials in the rat middle ear showed that the nylon prosthesis was encapsulated more rapidly than the two poly(methyl methacrylate) based implants. Several PMMA based implants were only partially covered at the 6 mnth stage by a tenuous capsule made up of collagen and a mixed inflammatory cell infiltrate. The nylon material was covered at the 3 mnth stage with a thin capsule and healthy fibroblasts.
在大鼠中耳植入三种不同的聚合物复合材料显示,尼龙假体比两种基于聚甲基丙烯酸甲酯的植入物更快地被包裹。几种基于聚甲基丙烯酸甲酯的植入物在6个月阶段仅部分被由胶原蛋白和混合炎性细胞浸润组成的薄弱包膜覆盖。尼龙材料在3个月阶段被一层薄包膜和健康的成纤维细胞覆盖。
