选择鼓膜成形材料,在于使移植物更适合受植耳,同时移植物必须有较好的稳定性,移植后容易上皮化、不易发生坏死。人类胎盘Ⅳ型网状胶原是一新型材料,首先这些胶原分子的抗原性是种间的,所以在人类中应用无免疫反应;其次此型胶原是基底膜的主要胶原,有助于上皮再生,特别适用于鼓膜成形;此外此型胶原较稳定,不需用醛类处理。但使用前必须进行消毒处理。本文用14只狗进行实验,先
Select the tympanic membrane forming materials, is to make the graft more suitable for the ear, while the graft must have good stability, easy to epithelialized after transplantation, less prone to necrosis. Human placenta type Ⅳ reticular collagen is a new type of material, first of all the antigenicity of these collagen molecules is interspecific, so the application of immune response in humans; followed by this type of collagen is the main collagen membrane, contribute to epithelial regeneration, Particularly suitable for tympanic membrane forming; In addition, this type of collagen is more stable, without aldehyde treatment. But before use must be disinfected. In this paper, 14 dogs experiment, first
