慢性化脓性中耳炎作听骨链重建术的方法众多 ,效果取决于多种因素。长期以来 ,人们致力于研究和制备人工听骨 ,作为听骨链赝复物的材料。其中 ,自体皮质骨赝复物存在被吸收降解的问题困扰着临床的应用。 1 995年以来 ,我们应用自体皮质骨加引导组织再生胶原膜 ,制成部分听骨赝 Chronic suppurative otitis media for the repair of ossicular chain in many ways, the effect depends on many factors. For a long time, people are devoted to studying and preparing artificial ossicles, which are used as materials for prostheses. Among them, autologous cortical bone prosthesis exists to absorb the degradation problems plagued the clinical application. Since 1995, we have applied autologous cortical bone to guide tissue regeneration of collagen membranes to form part of the otoskeleton
