On the basis of data reported in the literature, the authors have attempted to define the relationship between the functional results of cochlear implants and possible traumatic damage caused by the insertion of electrodes and their support into the cochlear bony walls. These findings show that traumatic conditions result in functional damage only when they involve the body of Corti's ganglion cells or the central part of their axon, whereas functional results are not influenced by traumatic damage to the peripheral part of the axon. Traumatic damage sustained by other non-nervous structures and the inevitable fibrosis and subsequent bone metaplasia processes which occur when a foreign body penetrates a living organism also appear to be unimportant.
基于文献报道的数据，作者试图明确人工耳蜗的功能结果与电极及其支撑物插入耳蜗骨壁可能造成的创伤性损伤之间的关系。这些研究结果表明，只有当创伤情况涉及柯蒂氏神经节细胞体或其轴突的中央部分时，才会导致功能损害，而轴突外周部分的创伤性损伤不会影响功能结果。其他非神经结构遭受的创伤性损伤以及异物侵入生物体时不可避免的纤维化和随后的骨化生过程似乎也不重要。
