一种新的多孔高密度聚乙烯生物材料 Pclyc-el~(Tm)最近已用于人的听骨链重建术。这种物质通过热溶加工制成。临床认为这种材料具有更好的组织耐受性,但尚无临床或动物实验的组织学材料证实之。实本验将 Polycel~(Tm)植入沙鼠中耳腔1～5个日后,进行组织切片,分别用光学显微镜及透射电镜进行观察,以研究其组织耐受性及其转归情况,结果发现,Polycel~(Tm)听骨膺复物外面被复有中耳粘膜。粘膜组织及骨组织可长入周边部的微孔内,故其固位较好,但仍见有异物巨细胞、空泡 A new porous high-density polyethylene biomaterial, Pclyc-el ~ (Tm), has recently been used for human ossicular chain reconstruction. This material is made by hot-melt processing. This material is clinically considered to have better tissue tolerance but is not yet confirmed by histological or experimental animal histology. In order to study the histocompatibility and prognosis of Polycel ~ (Tm) implanted into the middle ear cavity of gerbils 1 ~ 5 days later, the sections were stained by optical microscope and transmission electron microscopy. Results Found, Polycel ~ (Tm) Ossuary complex prosthesis outside the middle ear mucosa. Mucosal tissue and bone tissue can grow into the periphery of the micropores, so its retention is better, but still see foreign body giant cells, vacuoles
