The original concept of tympanoplasty included besides the closure of the middle ear, the removal of pathological middle ear components leaving intact the functional and healthy components. The special conditions that prevail in the middle ear (aeration, absence of intrinsic trauma) allow the reconstruction of the middle ear mechanics to a great extent. Animal experiments and clinical experience reveal good transplantation properties of denatured and preserved ear ossicles. They are partly replaced by the body's own true tissue, and preserve the original form over a period of years. Denatured dear drums with malleus, incus, and parts of the stapes give astounding acoustic results. The posterior bony canal wall in old radical cavities can be replaced by the posterior wall of the human temporal bone which has been preserved in Cialit.
鼓室成形术的最初概念除了包括封闭中耳外，还包括去除病理性中耳成分，同时保留功能正常和健康的成分。中耳存在的特殊条件（通气、无内在创伤）使得中耳力学在很大程度上得以重建。动物实验和临床经验表明，变性和保存的听小骨具有良好的移植特性。它们部分被机体自身的真正组织所替代，并在数年时间内保持原来的形态。带有锤骨、砧骨和部分镫骨的变性耳鼓能产生惊人的声学效果。陈旧性根治性中耳腔的后骨管壁可用保存在西阿利特中的人类颞骨后壁来替代。
