Alloplastic materials have been employer as replacement of the ossicular chain, in the reconstruction of the posterior wall of the outer ear and even in filling up the mastoid process. But owing to the restrictive laws in some countries relative to the transplantations of homologous ossicles and first of all for fear of viral transmissions through the procedures a new light is shed in this field of the ear surgery. In the paper the AA, make a critical revision of replacement alloplastic prosthesis considering the lately introduced materials. The majority of the prosthesis, specially those in plastic, give not, either in short or long term, worthy results. Autologous tissues are, as always have been, the first choice in the reconstructive management of the anatomy of the middle ear. Alloplastic materials being the second chance, by virtue of its recognized intolerance at long terms.
人工材料已被用于替代听骨链、重建外耳道后壁，甚至填充乳突。但由于一些国家对同种听骨移植的限制法律，首先是担心通过手术传播病毒，耳外科领域有了新的曙光。在本文中，作者对近期引入的材料制成的人工替代假体进行了批判性修订。大多数假体，特别是那些塑料材质的，无论短期还是长期，都没有给出值得肯定的结果。自体组织一如既往地是中耳解剖结构重建治疗的首选。人工材料由于其长期公认的不耐受性，只能作为第二选择。
